The Artistic License 2.0

Copyright (c) 2000-2006, The Perl Foundation.

Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.

Preamble

This license establishes the terms under which a given free software
Package may be copied, modified, distributed, and/or redistributed.
The intent is that the Copyright Holder maintains some artistic
control over the development of that Package while still keeping the
Package available as open source and free software.

You are always permitted to make arrangements wholly outside of this
license directly with the Copyright Holder of a given Package.  If the
terms of this license do not permit the full use that you propose to
make of the Package, you should contact the Copyright Holder and seek
a different licensing arrangement.

Definitions

    "Copyright Holder" means the individual(s) or organization(s)
    named in the copyright notice for the entire Package.

    "Contributor" means any party that has contributed code or other
    material to the Package, in accordance with the Copyright Holder's
    procedures.

    "You" and "your" means any person who would like to copy,
    distribute, or modify the Package.

    "Package" means the collection of files distributed by the
    Copyright Holder, and derivatives of that collection and/or of
    those files. A given Package may consist of either the Standard
    Version, or a Modified Version.

    "Distribute" means providing a copy of the Package or making it
    accessible to anyone else, or in the case of a company or
    organization, to others outside of your company or organization.

    "Distributor Fee" means any fee that you charge for Distributing
    this Package or providing support for this Package to another
    party.  It does not mean licensing fees.

    "Standard Version" refers to the Package if it has not been
    modified, or has been modified only in ways explicitly requested
    by the Copyright Holder.

    "Modified Version" means the Package, if it has been changed, and
    such changes were not explicitly requested by the Copyright
    Holder.

    "Original License" means this Artistic License as Distributed with
    the Standard Version of the Package, in its current version or as
    it may be modified by The Perl Foundation in the future.

    "Source" form means the source code, documentation source, and
    configuration files for the Package.

    "Compiled" form means the compiled bytecode, object code, binary,
    or any other form resulting from mechanical transformation or
    translation of the Source form.


Permission for Use and Modification Without Distribution

(1)  You are permitted to use the Standard Version and create and use
Modified Versions for any purpose without restriction, provided that
you do not Distribute the Modified Version.


Permissions for Redistribution of the Standard Version

(2)  You may Distribute verbatim copies of the Source form of the
Standard Version of this Package in any medium without restriction,
either gratis or for a Distributor Fee, provided that you duplicate
all of the original copyright notices and associated disclaimers.  At
your discretion, such verbatim copies may or may not include a
Compiled form of the Package.

(3)  You may apply any bug fixes, portability changes, and other
modifications made available from the Copyright Holder.  The resulting
Package will still be considered the Standard Version, and as such
will be subject to the Original License.


Distribution of Modified Versions of the Package as Source

(4)  You may Distribute your Modified Version as Source (either gratis
or for a Distributor Fee, and with or without a Compiled form of the
Modified Version) provided that you clearly document how it differs
from the Standard Version, including, but not limited to, documenting
any non-standard features, executables, or modules, and provided that
you do at least ONE of the following:

    (a)  make the Modified Version available to the Copyright Holder
    of the Standard Version, under the Original License, so that the
    Copyright Holder may include your modifications in the Standard
    Version.

    (b)  ensure that installation of your Modified Version does not
    prevent the user installing or running the Standard Version. In
    addition, the Modified Version must bear a name that is different
    from the name of the Standard Version.

    (c)  allow anyone who receives a copy of the Modified Version to
    make the Source form of the Modified Version available to others
    under

        (i)  the Original License or

        (ii)  a license that permits the licensee to freely copy,
        modify and redistribute the Modified Version using the same
        licensing terms that apply to the copy that the licensee
        received, and requires that the Source form of the Modified
        Version, and of any works derived from it, be made freely
        available in that license fees are prohibited but Distributor
        Fees are allowed.


Distribution of Compiled Forms of the Standard Version
or Modified Versions without the Source

(5)  You may Distribute Compiled forms of the Standard Version without
the Source, provided that you include complete instructions on how to
get the Source of the Standard Version.  Such instructions must be
valid at the time of your distribution.  If these instructions, at any
time while you are carrying out such distribution, become invalid, you
must provide new instructions on demand or cease further distribution.
If you provide valid instructions or cease distribution within thirty
days after you become aware that the instructions are invalid, then
you do not forfeit any of your rights under this license.

(6)  You may Distribute a Modified Version in Compiled form without
the Source, provided that you comply with Section 4 with respect to
the Source of the Modified Version.


Aggregating or Linking the Package

(7)  You may aggregate the Package (either the Standard Version or
Modified Version) with other packages and Distribute the resulting
aggregation provided that you do not charge a licensing fee for the
Package.  Distributor Fees are permitted, and licensing fees for other
components in the aggregation are permitted. The terms of this license
apply to the use and Distribution of the Standard or Modified Versions
as included in the aggregation.

(8) You are permitted to link Modified and Standard Versions with
other works, to embed the Package in a larger work of your own, or to
build stand-alone binary or bytecode versions of applications that
include the Package, and Distribute the result without restriction,
provided the result does not expose a direct interface to the Package.


Items That are Not Considered Part of a Modified Version

(9) Works (including, but not limited to, modules and scripts) that
merely extend or make use of the Package, do not, by themselves, cause
the Package to be a Modified Version.  In addition, such works are not
considered parts of the Package itself, and are not subject to the
terms of this license.


General Provisions

(10)  Any use, modification, and distribution of the Standard or
Modified Versions is governed by this Artistic License. By using,
modifying or distributing the Package, you accept this license. Do not
use, modify, or distribute the Package, if you do not accept this
license.

(11)  If your Modified Version has been derived from a Modified
Version made by someone other than you, you are nevertheless required
to ensure that your Modified Version complies with the requirements of
this license.

(12)  This license does not grant you the right to use any trademark,
service mark, tradename, or logo of the Copyright Holder.

(13)  This license includes the non-exclusive, worldwide,
free-of-charge patent license to make, have made, use, offer to sell,
sell, import and otherwise transfer the Package with respect to any
patent claims licensable by the Copyright Holder that are necessarily
infringed by the Package. If you institute patent litigation
(including a cross-claim or counterclaim) against any party alleging
that the Package constitutes direct or contributory patent
infringement, then this Artistic License to you shall terminate on the
date that such litigation is filed.

(14)  Disclaimer of Warranty:
THE PACKAGE IS PROVIDED BY THE COPYRIGHT HOLDER AND CONTRIBUTORS "AS
IS' AND WITHOUT ANY EXPRESS OR IMPLIED WARRANTIES. THE IMPLIED
WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR
NON-INFRINGEMENT ARE DISCLAIMED TO THE EXTENT PERMITTED BY YOUR LOCAL
LAW. UNLESS REQUIRED BY LAW, NO COPYRIGHT HOLDER OR CONTRIBUTOR WILL
BE LIABLE FOR ANY DIRECT, INDIRECT, INCIDENTAL, OR CONSEQUENTIAL
DAMAGES ARISING IN ANY WAY OUT OF THE USE OF THE PACKAGE, EVEN IF
ADVISED OF THE POSSIBILITY OF SUCH DAMAGE.

# npm - a JavaScript package manager

### Requirements

You should be running a currently supported version of [Node.js](https://nodejs.org/en/download/) to run **`npm`**.  For a list of which versions of Node.js are currently supported, please see the [Node.js releases](https://nodejs.org/en/about/previous-releases) page.

### Installation

**`npm`** comes bundled with [**`node`**](https://nodejs.org/), & most third-party distributions, by default. Officially supported downloads/distributions can be found at: [nodejs.org/en/download](https://nodejs.org/en/download)

#### Direct Download

You can download & install **`npm`** directly from [**npmjs**.com](https://npmjs.com/) using our custom `install.sh` script:

```bash
curl -qL https://www.npmjs.com/install.sh | sh
```

#### Node Version Managers

If you're looking to manage multiple versions of **`Node.js`** &/or **`npm`**, consider using a [node version manager](https://github.com/search?q=node+version+manager+archived%3Afalse&type=repositories&ref=advsearch)

### Usage

```bash
npm <command>
```

### Links & Resources

* [**Documentation**](https://docs.npmjs.com/) - Official docs & how-tos for all things **npm**
    * Note: you can also search docs locally with `npm help-search <query>`
* [**Bug Tracker**](https://github.com/npm/cli/issues) - Search or submit bugs against the CLI
* [**Roadmap**](https://github.com/orgs/github/projects/4247/views/1?filterQuery=npm) - Track & follow along with our public roadmap
* [**Community Feedback and Discussions**](https://github.com/orgs/community/discussions/categories/npm) - Contribute ideas & discussion around the npm registry, website & CLI
* [**RFCs**](https://github.com/npm/rfcs) - Contribute ideas & specifications for the API/design of the npm CLI
* [**Service Status**](https://status.npmjs.org/) - Monitor the current status & see incident reports for the website & registry
* [**Project Status**](https://npm.github.io/statusboard/) - See the health of all our maintained OSS projects in one view

* [**Support**](https://www.npmjs.com/support) - Experiencing problems with the **npm** [website](https://npmjs.com) or [registry](https://registry.npmjs.org)? File a ticket [here](https://www.npmjs.com/support)

### Acknowledgments

* `npm` is configured to use the **npm Public Registry** at [https://registry.npmjs.org](https://registry.npmjs.org) by default; Usage of this registry is subject to **Terms of Use** available at [https://npmjs.com/policies/terms](https://npmjs.com/policies/terms)
* You can configure `npm` to use any other compatible registry you prefer. You can read more about configuring third-party registries [here](https://docs.npmjs.com/cli/v7/using-npm/registry)

### FAQ on Branding

#### Is it "npm" or "NPM" or "Npm"?

**`npm`** should never be capitalized unless it is being displayed in a location that is customarily all-capitals (ex. titles on `man` pages).

#### Is "npm" an acronym for "Node Package Manager"?

Contrary to popular belief, **`npm`** **is not** in fact an acronym for "Node Package Manager"; It is a recursive bacronymic abbreviation for **"npm is not an acronym"** (if the project was named "ninaa", then it would be an acronym). The precursor to **`npm`** was actually a bash utility named **"pm"**, which was the shortform name of **"pkgmakeinst"** - a bash function that installed various things on various platforms. If **`npm`** were to ever have been considered an acronym, it would be as "node pm" or, potentially "new pm".

// Each command has a completion function that takes an options object and a cb
// The callback gets called with an error and an array of possible completions.
// The options object is built up based on the environment variables set by
// zsh or bash when calling a function for completion, based on the cursor
// position and the command line thus far.  These are:
// COMP_CWORD: the index of the "word" in the command line being completed
// COMP_LINE: the full command line thusfar as a string
// COMP_POINT: the cursor index at the point of triggering completion
//
// We parse the command line with nopt, like npm does, and then create an
// options object containing:
// words: array of words in the command line
// w: the index of the word being completed (ie, COMP_CWORD)
// word: the word being completed
// line: the COMP_LINE
// lineLength
// point: the COMP_POINT, usually equal to line length, but not always, eg if
// the user has pressed the left-arrow to complete an earlier word
// partialLine: the line up to the point
// partialWord: the word being completed (which might be ''), up to the point
// conf: a nopt parse of the command line
//
// When the implementation completion method returns its list of strings,
// and arrays of strings, we filter that by any that start with the
// partialWord, since only those can possibly be valid matches.
//
// Matches are wrapped with ' to escape them, if necessary, and then printed
// one per line for the shell completion method to consume in IFS=$'\n' mode
// as an array.

## DATA STRUCTURES

A `node_modules` tree is a logical graph of dependencies overlaid on a
physical tree of folders.

A `Node` represents a package folder on disk, either at the root of the
package, or within a `node_modules` folder.  The physical structure of the
folder tree is represented by the `node.parent` reference to the containing
folder, and `node.children` map of nodes within its `node_modules`
folder, where the key in the map is the name of the folder in
`node_modules`, and the value is the child node.

A node without a parent is a top of tree.

A `Link` represents a symbolic link to a package on disk.  This can be a
symbolic link to a package folder within the current tree, or elsewhere on
disk.  The `link.target` is a reference to the actual node.  Links differ
from Nodes in that dependencies are resolved from the _target_ location,
rather than from the link location.

An `Edge` represents a dependency relationship.  Each node has an `edgesIn`
set, and an `edgesOut` map.  Each edge has a `type` which specifies what
kind of dependency it represents: `'prod'` for regular dependencies,
`'peer'` for peerDependencies, `'dev'` for devDependencies, and
`'optional'` for optionalDependencies.  `edge.from` is a reference to the
node that has the dependency, and `edge.to` is a reference to the node that
requires the dependency.

As nodes are moved around in the tree, the graph edges are automatically
updated to point at the new module resolution targets.  In other words,
`edge.from`, `edge.name`, and `edge.spec` are immutable; `edge.to` is
updated automatically when a node's parent changes.

### class Node

All arborist trees are `Node` objects.  A `Node` refers
to a package folder, which may have children in `node_modules`.

* `node.name` The name of this node's folder in `node_modules`.
* `node.parent` Physical parent node in the tree.  The package in whose
  `node_modules` folder this package lives.  Null if node is top of tree.

    Setting `node.parent` will automatically update `node.location` and all
    graph edges affected by the move.

* `node.meta` A `Shrinkwrap` object which looks up `resolved` and
  `integrity` values for all modules in this tree.  Only relevant on `root`
  nodes.

* `node.children` Map of packages located in the node's `node_modules`
  folder.
* `node.package` The contents of this node's `package.json` file.
* `node.path` File path to this package.  If the node is a link, then this
  is the path to the link, not to the link target.  If the node is _not_ a
  link, then this matches `node.realpath`.
* `node.realpath` The full real filepath on disk where this node lives.
* `node.location` A slash-normalized relative path from the root node to
  this node's path.
* `node.isLink` Whether this represents a symlink.  Always `false` for Node
  objects, always `true` for Link objects.
* `node.isRoot` True if this node is a root node.  (Ie, if `node.root ===
  node`.)
* `node.root` The root node where we are working.  If not assigned to some
  other value, resolves to the node itself.  (Ie, the root node's `root`
  property refers to itself.)
* `node.isTop` True if this node is the top of its tree (ie, has no
  `parent`, false otherwise).
* `node.top` The top node in this node's tree.  This will be equal to
  `node.root` for simple trees, but link targets will frequently be outside
  of (or nested somewhere within) a `node_modules` hierarchy, and so will
  have a different `top`.
* `node.dev`, `node.optional`, `node.devOptional`, `node.peer`, Indicators
  as to whether this node is a dev, optional, and/or peer dependency.
  These flags are relevant when pruning dependencies out of the tree or
  deciding what to reify.  See **Package Dependency Flags** below for
  explanations.
* `node.edgesOut` Edges in the dependency graph indicating nodes that this
  node depends on, which resolve its dependencies.
* `node.edgesIn` Edges in the dependency graph indicating nodes that depend
  on this node.

* `extraneous` True if this package is not required by any other for any
  reason.  False for top of tree.

* `node.resolve(name)`  Identify the node that will be returned when code
  in this package runs `require(name)`

* `node.errors` Array of errors encountered while parsing package.json or
  version specifiers.

### class Link

Link objects represent a symbolic link within the `node_modules` folder.
They have most of the same properties and methods as `Node` objects, with a
few differences.

* `link.target` A Node object representing the package that the link
  references.  If this is a Node already present within the tree, then it
  will be the same object.  If it's outside of the tree, then it will be
  treated as the top of its own tree.
* `link.isLink` Always true.
* `link.children` This is always an empty map, since links don't have their
  own children directly.

### class Edge

Edge objects represent a dependency relationship a package node to the
point in the tree where the dependency will be loaded.  As nodes are moved
within the tree, Edges automatically update to point to the appropriate
location.

* `new Edge({ from, type, name, spec })`  Creates a new edge with the
  specified fields.  After instantiation, none of the fields can be
  changed directly.
* `edge.from` The node that has the dependency.
* `edge.type` The type of dependency.  One of `'prod'`, `'dev'`, `'peer'`,
  or `'optional'`.
* `edge.name` The name of the dependency.  Ie, the key in the
  relevant `package.json` dependencies object.
* `edge.spec` The specifier that is required.  This can be a version,
  range, tag name, git url, or tarball URL.  Any specifier allowed by npm
  is supported.
* `edge.to` Automatically set to the node in the tree that matches the
  `name` field.
* `edge.valid` True if `edge.to` satisfies the specifier.
* `edge.error` A string indicating the type of error if there is a problem,
  or `null` if it's valid.  Values, in order of precedence:
    * `DETACHED` Indicates that the edge has been detached from its
      `edge.from` node, typically because a new edge was created when a
      dependency specifier was modified.
    * `MISSING` Indicates that the dependency is unmet.  Note that this is
      _not_ set for unmet dependencies of the `optional` type.
    * `PEER LOCAL` Indicates that a `peerDependency` is found in the
      node's local `node_modules` folder, and the node is not the top of
      the tree.  This violates the `peerDependency` contract, because it
      means that the dependency is not a peer.
    * `INVALID` Indicates that the dependency does not satisfy `edge.spec`.
* `edge.reload()` Re-resolve to find the appropriate value for `edge.to`.
  Called automatically from the `Node` class when the tree is mutated.

### Package Dependency Flags

The dependency type of a node can be determined efficiently by looking at
the `dev`, `optional`, and `devOptional` flags on the node object.  These
are updated by arborist when necessary whenever the tree is modified in
such a way that the dependency graph can change, and are relevant when
pruning nodes from the tree.

```

* If none of these flags are set, then the node is required by the
  dependency and/or peerDependency hierarchy.  It should not be pruned.
* If _both_ `node.dev` and `node.optional` are set, then the node is an
  optional dependency of one of the packages in the devDependency
  hierarchy.  It should be pruned if _either_ dev or optional deps are
  being removed.
* If `node.dev` is set, but `node.optional` is not, then the node is
  required in the devDependency hierarchy.  It should be pruned if dev
  dependencies are being removed.
* If `node.optional` is set, but `node.dev` is not, then the node is
  required in the optionalDependency hierarchy.  It should be pruned if
  optional dependencies are being removed.
* If `node.devOptional` is set, then the node is a (non-optional)
  dependency within the devDependency hierarchy, _and_ a dependency
  within the `optionalDependency` hierarchy.  It should be pruned if
  _both_ dev and optional dependencies are being removed.
* If `node.peer` is set, then all the same semantics apply as above, except
  that the dep is brought in by a peer dep at some point, rather than a
  normal non-peer dependency.

Note: `devOptional` is only set in the shrinkwrap/package-lock file if
_neither_ `dev` nor `optional` are set, as it would be redundant.

  Additionally:

  * --loglevel=warn|--quiet will supppress the printing of package trees
  * --logfile <file|bool> will output logs to a file
  * --timing will show timing information
  * Instead of 'npm install <pkg>', use 'arborist reify --add=<pkg>'.
    The '--add=<pkg>' option can be specified multiple times.
  * Instead of 'npm rm <pkg>', use 'arborist reify --rm=<pkg>'.
    The '--rm=<pkg>' option can be specified multiple times.
  * Instead of 'npm update', use 'arborist reify --update-all'.
  * 'npm audit fix' is 'arborist audit --fix'

   * with an Arborist refactor or rewrite. Embedded logic in Nodes and Links,
   * and the incremental state of building trees and reifying contains too many
   * assumptions to do a linked mode properly.
   *
   * Instead, this approach takes a tree built from build-ideal-tree, and
   * returns a new tree-like structure without the embedded logic of Node and
   * Link classes.
   *
   * Since the RFC requires leaving the package-lock in place, this approach
   * temporarily replaces the tree state for a couple of steps of reifying.

// Internal methods used by buildIdealTree.
// Answer the question: "can I put this dep here?"
//
// IMPORTANT: *nothing* in this class should *ever* modify or mutate the tree
// at all.  The contract here is strictly limited to read operations.  We call
// this in the process of walking through the ideal tree checking many
// different potential placement targets for a given node.  If a change is made
// to the tree along the way, that can cause serious problems!
//
// In order to enforce this restriction, in debug mode, canPlaceDep() will
// snapshot the tree at the start of the process, and then at the end, will
// verify that it still matches the snapshot, and throw an error if any changes
// occurred.
//
// The algorithm is roughly like this:
// - check the node itself:
//   - if there is no version present, and no conflicting edges from target,
//     OK, provided all peers can be placed at or above the target.
//   - if the current version matches, KEEP
//   - if there is an older version present, which can be replaced, then
//     - if satisfying and preferDedupe? KEEP
//     - else: REPLACE
//   - if there is a newer version present, and preferDedupe, REPLACE
//   - if the version present satisfies the edge, KEEP
//   - else: CONFLICT
// - if the node is not in conflict, check each of its peers:
//   - if the peer can be placed in the target, continue
//   - else if the peer can be placed in a parent, and there is no other
//     conflicting version shadowing it, continue
//   - else CONFLICT
// - If the peers are not in conflict, return the original node's value
//
// An exception to this logic is that if the target is the deepest location
// that a node can be placed, and the conflicting node can be placed deeper,
// then we will return REPLACE rather than CONFLICT, and Arborist will queue
// the replaced node for resolution elsewhere.

# `@npmcli/config`

Configuration management for the npm cli.

This module is the spiritual descendant of
[`npmconf`](http://npm.im/npmconf), and the code that once lived in npm's
`lib/config/` folder.

It does the management of configuration files that npm uses, but
importantly, does _not_ define all the configuration defaults or types, as
those parts make more sense to live within the npm CLI itself.

The only exceptions:

- The `prefix` config value has some special semantics, setting the local
  prefix if specified on the CLI options and not in global mode, or the
  global prefix otherwise.
- The `project` config file is loaded based on the local prefix (which can
  only be set by the CLI config options, and otherwise defaults to a walk
  up the folder tree to the first parent containing a `node_modules`
  folder, `package.json` file, or `package-lock.json` file.)
- The `userconfig` value, as set by the environment and CLI (defaulting to
  `~/.npmrc`, is used to load user configs.
- The `globalconfig` value, as set by the environment, CLI, and
  `userconfig` file (defaulting to `$PREFIX/etc/npmrc`) is used to load
  global configs.
- A `builtin` config, read from a `npmrc` file in the root of the npm
  project itself, overrides all defaults.

The resulting hierarchy of configs:

- CLI switches.  eg `--some-key=some-value` on the command line.  These are
  parsed by [`nopt`](http://npm.im/nopt), which is not a great choice, but
  it's the one that npm has used forever, and changing it will be
  difficult.
- Environment variables.  eg `npm_config_some_key=some_value` in the
  environment.  There is no way at this time to modify this prefix.
- INI-formatted project configs.  eg `some-key = some-value` in the
  `localPrefix` folder (ie, the `cwd`, or its nearest parent that contains
  either a `node_modules` folder or `package.json` file.)
- INI-formatted userconfig file.  eg `some-key = some-value` in `~/.npmrc`.
  The `userconfig` config value can be overridden by the `cli`, `env`, or
  `project` configs to change this value.
- INI-formatted globalconfig file.  eg `some-key = some-value` in
  the `globalPrefix` folder, which is inferred by looking at the location
  of the node executable, or the `prefix` setting in the `cli`, `env`,
  `project`, or `userconfig`.  The `globalconfig` value at any of those
  levels can override this.
- INI-formatted builtin config file.  eg `some-key = some-value` in
  `/usr/local/lib/node_modules/npm/npmrc`.  This is not configurable, and
  is determined by looking in the `npmPath` folder.
- Default values (passed in by npm when it loads this module).

## USAGE

```js
const Config = require('@npmcli/config')
const { shorthands, definitions, flatten } = require('@npmcli/config/lib/definitions')

const conf = new Config({
  // path to the npm module being run
  npmPath: resolve(__dirname, '..'),
  definitions,
  shorthands,
  flatten,
  // optional, defaults to process.argv
  // argv: [] <- if you are using this package in your own cli
  //             and dont want to have colliding argv
  argv: process.argv,
  // optional, defaults to process.env
  env: process.env,
  // optional, defaults to process.execPath
  execPath: process.execPath,
  // optional, defaults to process.platform
  platform: process.platform,
  // optional, defaults to process.cwd()
  cwd: process.cwd(),
})

// emits log events on the process object
// see `proc-log` for more info
process.on('log', (level, ...args) => {
  console.log(level, ...args)
})

// returns a promise that fails if config loading fails, and
// resolves when the config object is ready for action
conf.load().then(() => {
  conf.validate()
  console.log('loaded ok! some-key = ' + conf.get('some-key'))
}).catch(er => {
  console.error('error loading configs!', er)
})
```

## API

The `Config` class is the sole export.

```js
const Config = require('@npmcli/config')
```

### static `Config.typeDefs`

The type definitions passed to `nopt` for CLI option parsing and known
configuration validation.

### constructor `new Config(options)`

Options:

- `types` Types of all known config values.  Note that some are effectively
  given semantic value in the config loading process itself.
- `shorthands` An object mapping a shorthand value to an array of CLI
  arguments that replace it.
- `defaults` Default values for each of the known configuration keys.
  These should be defined for all configs given a type, and must be valid.
- `npmPath` The path to the `npm` module, for loading the `builtin` config
  file.
- `cwd` Optional, defaults to `process.cwd()`, used for inferring the
  `localPrefix` and loading the `project` config.
- `platform` Optional, defaults to `process.platform`.  Used when inferring
  the `globalPrefix` from the `execPath`, since this is done diferently on
  Windows.
- `execPath` Optional, defaults to `process.execPath`.  Used to infer the
  `globalPrefix`.
- `env` Optional, defaults to `process.env`.  Source of the environment
  variables for configuration.
- `argv` Optional, defaults to `process.argv`.  Source of the CLI options
  used for configuration.

Returns a `config` object, which is not yet loaded.

Fields:

- `config.globalPrefix` The prefix for `global` operations.  Set by the
  `prefix` config value, or defaults based on the location of the
  `execPath` option.
- `config.localPrefix` The prefix for `local` operations.  Set by the
  `prefix` config value on the CLI only, or defaults to either the `cwd` or
  its nearest ancestor containing a `node_modules` folder or `package.json`
  file.
- `config.sources` A read-only `Map` of the file (or a comment, if no file
  found, or relevant) to the config level loaded from that source.
- `config.data` A `Map` of config level to `ConfigData` objects.  These
  objects should not be modified directly under any circumstances.
  - `source` The source where this data was loaded from.
  - `raw` The raw data used to generate this config data, as it was parsed
    initially from the environment, config file, or CLI options.
  - `data` The data object reflecting the inheritance of configs up to this
    point in the chain.
  - `loadError` Any errors encountered that prevented the loading of this
    config data.
- `config.list` A list sorted in priority of all the config data objects in
  the prototype chain.  `config.list[0]` is the `cli` level,
  `config.list[1]` is the `env` level, and so on.
- `cwd` The `cwd` param
- `env` The `env` param
- `argv` The `argv` param
- `execPath` The `execPath` param
- `platform` The `platform` param
- `defaults` The `defaults` param
- `shorthands` The `shorthands` param
- `types` The `types` param
- `npmPath` The `npmPath` param
- `globalPrefix` The effective `globalPrefix`
- `localPrefix` The effective `localPrefix`
- `prefix` If `config.get('global')` is true, then `globalPrefix`,
  otherwise `localPrefix`
- `home` The user's home directory, found by looking at `env.HOME` or
  calling `os.homedir()`.
- `loaded` A boolean indicating whether or not configs are loaded
- `valid` A getter that returns `true` if all the config objects are valid.
  Any data objects that have been modified with `config.set(...)` will be
  re-evaluated when `config.valid` is read.

### `config.load()`

Load configuration from the various sources of information.

Returns a `Promise` that resolves when configuration is loaded, and fails
if a fatal error is encountered.

### `config.find(key)`

Find the effective place in the configuration levels a given key is set.
Returns one of: `cli`, `env`, `project`, `user`, `global`, `builtin`, or
`default`.

Returns `null` if the key is not set.

### `config.get(key, where = 'cli')`

Load the given key from the config stack.

### `config.set(key, value, where = 'cli')`

Set the key to the specified value, at the specified level in the config
stack.

### `config.delete(key, where = 'cli')`

Delete the configuration key from the specified level in the config stack.

### `config.validate(where)`

Verify that all known configuration options are set to valid values, and
log a warning if they are invalid.

Invalid auth options will cause this method to throw an error with a `code`
property of `ERR_INVALID_AUTH`, and a `problems` property listing the specific
concerns with the current configuration.

If `where` is not set, then all config objects are validated.

Returns `true` if all configs are valid.

Note that it's usually enough (and more efficient) to just check
`config.valid`, since each data object is marked for re-evaluation on every
`config.set()` operation.

### `config.repair(problems)`

Accept an optional array of problems (as thrown by `config.validate()`) and
perform the necessary steps to resolve them. If no problems are provided,
this method will call `config.validate()` internally to retrieve them.

Note that you must `await config.save('user')` in order to persist the changes.

### `config.isDefault(key)`

Returns `true` if the value is coming directly from the
default definitions, if the current value for the key config is
coming from any other source, returns `false`.

This method can be used for avoiding or tweaking default values, e.g:

>  Given a global default definition of foo='foo' it's possible to read that
>  value such as:
>
>  ```js
>     const save = config.get('foo')
>  ```
>
>  Now in a different place of your app it's possible to avoid using the `foo`
>  default value, by checking to see if the current config value is currently
>  one that was defined by the default definitions:
>
>  ```js
>     const save = config.isDefault('foo') ? 'bar' : config.get('foo')
>  ```

### `config.save(where)`

Save the config file specified by the `where` param.  Must be one of
`project`, `user`, `global`, `builtin`.
// class that describes a config key we know about
// this keeps us from defining a config key and not
// providing a default, description, etc.

// that they affect the `saveType` flat option.  Then the config.flat
// object has a `get saveType () { ... }` that looks at the "real"
// config settings from files etc and returns the appropriate value.
//
// Getters will also (maybe?) give us a hook to audit flat option
// usage, so we can document and group these more appropriately.
//
// This will be a problem with cases where we currently do:
// const opts = { ...npm.flatOptions, foo: 'bar' }, but we can maybe
// instead do `npm.config.set('foo', 'bar')` prior to passing the
// config object down where it needs to go.
//
// This way, when we go hunting for "where does saveType come from anyway!?"
// while fixing some Arborist bug, we won't have to hunt through too
// many places.

// XXX: We should really deprecate all these `--save-blah` switches
// in favor of a single `--save-type` option.  The unfortunate shortcut
// we took for `--save-peer --save-optional` being `--save-type=peerOptional`
// makes this tricky, and likely a breaking change.

// Define all config keys we know about.  They are indexed by their own key for
// ease of lookup later.  This duplication is an optimization so that we don't
// have to do an extra function call just to "reuse" the key in both places.

// - Use of the assert module has been replaced with core's error system.
// - All code related to the glob dependency has been removed.
// - Bring your own custom fs module is not currently supported.
// - Some basic code cleanup.
// changes here:
// - remove all callback related code
// - drop sync support
// - change assertions back to non-internal methods (see options.js)
// - throws ENOTDIR when rmdir gets an ENOENT for a path that exists in Windows

# @npmcli/installed-package-contents

Get the list of files installed in a package in node_modules, including
bundled dependencies.

This is useful if you want to remove a package node from the tree _without_
removing its child nodes, for example to extract a new version of the
dependency into place safely.

It's sort of the reflection of [npm-packlist](http://npm.im/npm-packlist),
but for listing out the _installed_ files rather than the files that _will_
be installed.  This is of course a much simpler operation, because we don't
have to handle ignore files or package.json `files` lists.

## USAGE

```js
// programmatic usage
const pkgContents = require('@npmcli/installed-package-contents')

pkgContents({ path: 'node_modules/foo', depth: 1 }).then(files => {
  // files is an array of items that need to be passed to
  // rimraf or moved out of the way to make the folder empty
  // if foo bundled dependencies, those will be included.
  // It will not traverse into child directories, because we set
  // depth:1 in the options.
  // If the folder doesn't exist, this returns an empty array.
})

pkgContents({ path: 'node_modules/foo', depth: Infinity }).then(files => {
  // setting depth:Infinity tells it to keep walking forever
  // until it hits something that isn't a directory, so we'll
  // just get the list of all files, but not their containing
  // directories.
})
```

As a CLI:

```bash
$ installed-package-contents node_modules/bundle-some -d1
node_modules/.bin/some
node_modules/bundle-some/package.json
node_modules/bundle-some/node_modules/@scope/baz
node_modules/bundle-some/node_modules/.bin/foo
node_modules/bundle-some/node_modules/foo
```

CLI options:

```
Usage:
  installed-package-contents <path> [-d<n> --depth=<n>]

Lists the files installed for a package specified by <path>.

Options:
  -d<n> --depth=<n>   Provide a numeric value ("Infinity" is allowed)
                      to specify how deep in the file tree to traverse.
                      Default=1
  -h --help           Show this usage information
```

## OPTIONS

* `depth` Number, default `1`.  How deep to traverse through folders to get
    contents.  Typically you'd want to set this to either `1` (to get the
    surface files and folders) or `Infinity` (to get all files), but any
    other positive number is supported as well.  If set to `0` or a
    negative number, returns the path provided and (if it is a package) its
    set of linked bins.
* `path` Required.  Path to the package in `node_modules` where traversal
    should begin.

## RETURN VALUE

A Promise that resolves to an array of fully-resolved files and folders
matching the criteria.  This includes all bundled dependencies in
`node_modules`, and any linked executables in `node_modules/.bin` that the
package caused to be installed.

An empty or missing package folder will return an empty array.  Empty
directories _within_ package contents are listed, even if the `depth`
argument would cause them to be traversed into.

## CAVEAT

If using this module to generate a list of files that should be recursively
removed to clear away the package, note that this will leave empty
directories behind in certain cases:

- If all child packages are bundled dependencies, then the
    `node_modules` folder will remain.
- If all child packages within a given scope were bundled dependencies,
    then the `node_modules/@scope` folder will remain.
- If all linked bin scripts were removed, then an empty `node_modules/.bin`
    folder will remain.

In the interest of speed and algorithmic complexity, this module does _not_
do a subsequent readdir to see if it would remove all directory entries,
though it would be easier to look at if it returned `node_modules` or
`.bin` in that case rather than the contents.  However, if the intent is to
pass these arguments to `rimraf`, it hardly makes sense to do _two_
`readdir` calls just so that we can have the luxury of having to make a
third.

Since the primary use case is to delete a package's contents so that they
can be re-filled with a new version of that package, this caveat does not
pose a problem.  Empty directories are already ignored by both npm and git.

      "Source" form shall mean the preferred form for making modifications,
      including but not limited to software source code, documentation
      source, and configuration files.

      "Object" form shall mean any form resulting from mechanical
      transformation or translation of a Source form, including but
      not limited to compiled object code, generated documentation,
      and conversions to other media types.

      "Work" shall mean the work of authorship, whether in Source or
      Object form, made available under the License, as indicated by a
      copyright notice that is included in or attached to the work
      (an example is provided in the Appendix below).

      "Derivative Works" shall mean any work, whether in Source or Object
      form, that is based on (or derived from) the Work and for which the
      editorial revisions, annotations, elaborations, or other modifications
      represent, as a whole, an original work of authorship. For the purposes
      of this License, Derivative Works shall not include works that remain
      separable from, or merely link (or bind by name) to the interfaces of,
      the Work and Derivative Works thereof.

      "Contribution" shall mean any work of authorship, including
      the original version of the Work and any modifications or additions
      to that Work or Derivative Works thereof, that is intentionally
      submitted to Licensor for inclusion in the Work by the copyright owner
      or by an individual or Legal Entity authorized to submit on behalf of
      the copyright owner. For the purposes of this definition, "submitted"
      means any form of electronic, verbal, or written communication sent

      Licensor for the purpose of discussing and improving the Work, but
      excluding communication that is conspicuously marked or otherwise
      designated in writing by the copyright owner as "Not a Contribution."

      "Contributor" shall mean Licensor and any individual or Legal Entity
      on behalf of whom a Contribution has been received by Licensor and
      subsequently incorporated within the Work.

   2. Grant of Copyright License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      copyright license to reproduce, prepare Derivative Works of,
      publicly display, publicly perform, sublicense, and distribute the
      Work and such Derivative Works in Source or Object form.

   3. Grant of Patent License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      (except as stated in this section) patent license to make, have made,
      use, offer to sell, sell, import, and otherwise transfer the Work,
      where such license applies only to those patent claims licensable
      by such Contributor that are necessarily infringed by their
      Contribution(s) alone or by combination of their Contribution(s)
      with the Work to which such Contribution(s) was submitted. If You
      institute patent litigation against any entity (including a
      cross-claim or counterclaim in a lawsuit) alleging that the Work
      or a Contribution incorporated within the Work constitutes direct
      or contributory patent infringement, then any patent licenses
      granted to You under this License for that Work shall terminate
      as of the date such litigation is filed.

   4. Redistribution. You may reproduce and distribute copies of the
      Work or Derivative Works thereof in any medium, with or without
      modifications, and in Source or Object form, provided that You
      meet the following conditions:

      (a) You must give any other recipients of the Work or
          Derivative Works a copy of this License; and

      (b) You must cause any modified files to carry prominent notices
          stating that You changed the files; and

      (c) You must retain, in the Source form of any Derivative Works
          that You distribute, all copyright, patent, trademark, and
          attribution notices from the Source form of the Work,
          excluding those notices that do not pertain to any part of
          the Derivative Works; and

      (d) If the Work includes a "NOTICE" text file as part of its
          distribution, then any Derivative Works that You distribute must
          include a readable copy of the attribution notices contained
          within such NOTICE file, excluding those notices that do not
          pertain to any part of the Derivative Works, in at least one
          of the following places: within a NOTICE text file distributed
          as part of the Derivative Works; within the Source form or
          documentation, if provided along with the Derivative Works; or,
          within a display generated by the Derivative Works, if and
          wherever such third-party notices normally appear. The contents
          of the NOTICE file are for informational purposes only and
          do not modify the License. You may add Your own attribution
          notices within Derivative Works that You distribute, alongside
          or as an addendum to the NOTICE text from the Work, provided
          that such additional attribution notices cannot be construed
          as modifying the License.

      You may add Your own copyright statement to Your modifications and
      may provide additional or different license terms and conditions
      for use, reproduction, or distribution of Your modifications, or
      for any such Derivative Works as a whole, provided Your use,
      reproduction, and distribution of the Work otherwise complies with
      the conditions stated in this License.

   5. Submission of Contributions. Unless You explicitly state otherwise,
      any Contribution intentionally submitted for inclusion in the Work
      by You to the Licensor shall be under the terms and conditions of
      this License, without any additional terms or conditions.
      Notwithstanding the above, nothing herein shall supersede or modify
      the terms of any separate license agreement you may have executed
      with Licensor regarding such Contributions.

   6. Trademarks. This License does not grant permission to use the trade
      names, trademarks, service marks, or product names of the Licensor,
      except as required for reasonable and customary use in describing the
      origin of the Work and reproducing the content of the NOTICE file.

   7. Disclaimer of Warranty. Unless required by applicable law or
      agreed to in writing, Licensor provides the Work (and each
      Contributor provides its Contributions) on an "AS IS" BASIS,
      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
      implied, including, without limitation, any warranties or conditions
      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
      PARTICULAR PURPOSE. You are solely responsible for determining the
      appropriateness of using or redistributing the Work and assume any
      risks associated with Your exercise of permissions under this License.

   8. Limitation of Liability. In no event and under no legal theory,
      whether in tort (including negligence), contract, or otherwise,
      unless required by applicable law (such as deliberate and grossly
      negligent acts) or agreed to in writing, shall any Contributor be
      liable to You for damages, including any direct, indirect, special,
      incidental, or consequential damages of any character arising as a
      result of this License or out of the use or inability to use the
      Work (including but not limited to damages for loss of goodwill,
      work stoppage, computer failure or malfunction, or any and all
      other commercial damages or losses), even if such Contributor
      has been advised of the possibility of such damages.

   9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
      of your accepting any such warranty or additional liability.

      "Object" form shall mean any form resulting from mechanical
      transformation or translation of a Source form, including but
      not limited to compiled object code, generated documentation,
      and conversions to other media types.

      "Work" shall mean the work of authorship, whether in Source or
      Object form, made available under the License, as indicated by a
      copyright notice that is included in or attached to the work
      (an example is provided in the Appendix below).

      "Derivative Works" shall mean any work, whether in Source or Object
      form, that is based on (or derived from) the Work and for which the
      editorial revisions, annotations, elaborations, or other modifications
      represent, as a whole, an original work of authorship. For the purposes
      of this License, Derivative Works shall not include works that remain
      separable from, or merely link (or bind by name) to the interfaces of,
      the Work and Derivative Works thereof.

      "Contribution" shall mean any work of authorship, including
      the original version of the Work and any modifications or additions
      to that Work or Derivative Works thereof, that is intentionally
      submitted to Licensor for inclusion in the Work by the copyright owner
      or by an individual or Legal Entity authorized to submit on behalf of
      the copyright owner. For the purposes of this definition, "submitted"
      means any form of electronic, verbal, or written communication sent

      designated in writing by the copyright owner as "Not a Contribution."

      "Contributor" shall mean Licensor and any individual or Legal Entity
      on behalf of whom a Contribution has been received by Licensor and
      subsequently incorporated within the Work.

   2. Grant of Copyright License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      copyright license to reproduce, prepare Derivative Works of,
      publicly display, publicly perform, sublicense, and distribute the
      Work and such Derivative Works in Source or Object form.

   3. Grant of Patent License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      (except as stated in this section) patent license to make, have made,
      use, offer to sell, sell, import, and otherwise transfer the Work,
      where such license applies only to those patent claims licensable
      by such Contributor that are necessarily infringed by their
      Contribution(s) alone or by combination of their Contribution(s)
      with the Work to which such Contribution(s) was submitted. If You
      institute patent litigation against any entity (including a
      cross-claim or counterclaim in a lawsuit) alleging that the Work
      or a Contribution incorporated within the Work constitutes direct
      or contributory patent infringement, then any patent licenses
      granted to You under this License for that Work shall terminate
      as of the date such litigation is filed.

   4. Redistribution. You may reproduce and distribute copies of the
      Work or Derivative Works thereof in any medium, with or without
      modifications, and in Source or Object form, provided that You
      meet the following conditions:

      (a) You must give any other recipients of the Work or
          Derivative Works a copy of this License; and

      (b) You must cause any modified files to carry prominent notices
          stating that You changed the files; and

      (c) You must retain, in the Source form of any Derivative Works
          that You distribute, all copyright, patent, trademark, and
          attribution notices from the Source form of the Work,
          excluding those notices that do not pertain to any part of
          the Derivative Works; and

      (d) If the Work includes a "NOTICE" text file as part of its
          distribution, then any Derivative Works that You distribute must
          include a readable copy of the attribution notices contained
          within such NOTICE file, excluding those notices that do not
          pertain to any part of the Derivative Works, in at least one
          of the following places: within a NOTICE text file distributed
          as part of the Derivative Works; within the Source form or
          documentation, if provided along with the Derivative Works; or,
          within a display generated by the Derivative Works, if and
          wherever such third-party notices normally appear. The contents
          of the NOTICE file are for informational purposes only and
          do not modify the License. You may add Your own attribution
          notices within Derivative Works that You distribute, alongside
          or as an addendum to the NOTICE text from the Work, provided
          that such additional attribution notices cannot be construed
          as modifying the License.

      You may add Your own copyright statement to Your modifications and
      may provide additional or different license terms and conditions
      for use, reproduction, or distribution of Your modifications, or
      for any such Derivative Works as a whole, provided Your use,
      reproduction, and distribution of the Work otherwise complies with
      the conditions stated in this License.

   5. Submission of Contributions. Unless You explicitly state otherwise,
      any Contribution intentionally submitted for inclusion in the Work
      by You to the Licensor shall be under the terms and conditions of
      this License, without any additional terms or conditions.
      Notwithstanding the above, nothing herein shall supersede or modify
      the terms of any separate license agreement you may have executed
      with Licensor regarding such Contributions.

   6. Trademarks. This License does not grant permission to use the trade
      names, trademarks, service marks, or product names of the Licensor,
      except as required for reasonable and customary use in describing the
      origin of the Work and reproducing the content of the NOTICE file.

   7. Disclaimer of Warranty. Unless required by applicable law or
      agreed to in writing, Licensor provides the Work (and each
      Contributor provides its Contributions) on an "AS IS" BASIS,
      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
      implied, including, without limitation, any warranties or conditions
      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
      PARTICULAR PURPOSE. You are solely responsible for determining the
      appropriateness of using or redistributing the Work and assume any
      risks associated with Your exercise of permissions under this License.

   8. Limitation of Liability. In no event and under no legal theory,
      whether in tort (including negligence), contract, or otherwise,
      unless required by applicable law (such as deliberate and grossly
      negligent acts) or agreed to in writing, shall any Contributor be
      liable to You for damages, including any direct, indirect, special,
      incidental, or consequential damages of any character arising as a
      result of this License or out of the use or inability to use the
      Work (including but not limited to damages for loss of goodwill,
      work stoppage, computer failure or malfunction, or any and all
      other commercial damages or losses), even if such Contributor
      has been advised of the possibility of such damages.

   9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
      of your accepting any such warranty or additional liability.

   END OF TERMS AND CONDITIONS

   APPENDIX: How to apply the Apache License to your work.

      "Object" form shall mean any form resulting from mechanical
      transformation or translation of a Source form, including but
      not limited to compiled object code, generated documentation,
      and conversions to other media types.

      "Work" shall mean the work of authorship, whether in Source or
      Object form, made available under the License, as indicated by a
      copyright notice that is included in or attached to the work
      (an example is provided in the Appendix below).

      "Derivative Works" shall mean any work, whether in Source or Object
      form, that is based on (or derived from) the Work and for which the
      editorial revisions, annotations, elaborations, or other modifications
      represent, as a whole, an original work of authorship. For the purposes
      of this License, Derivative Works shall not include works that remain
      separable from, or merely link (or bind by name) to the interfaces of,
      the Work and Derivative Works thereof.

      "Contribution" shall mean any work of authorship, including
      the original version of the Work and any modifications or additions
      to that Work or Derivative Works thereof, that is intentionally

      designated in writing by the copyright owner as "Not a Contribution."

      "Contributor" shall mean Licensor and any individual or Legal Entity
      on behalf of whom a Contribution has been received by Licensor and
      subsequently incorporated within the Work.

   2. Grant of Copyright License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      copyright license to reproduce, prepare Derivative Works of,
      publicly display, publicly perform, sublicense, and distribute the
      Work and such Derivative Works in Source or Object form.

   3. Grant of Patent License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      (except as stated in this section) patent license to make, have made,
      use, offer to sell, sell, import, and otherwise transfer the Work,
      where such license applies only to those patent claims licensable
      by such Contributor that are necessarily infringed by their
      Contribution(s) alone or by combination of their Contribution(s)
      with the Work to which such Contribution(s) was submitted. If You
      institute patent litigation against any entity (including a
      cross-claim or counterclaim in a lawsuit) alleging that the Work
      or a Contribution incorporated within the Work constitutes direct
      or contributory patent infringement, then any patent licenses
      granted to You under this License for that Work shall terminate
      as of the date such litigation is filed.

   4. Redistribution. You may reproduce and distribute copies of the
      Work or Derivative Works thereof in any medium, with or without
      modifications, and in Source or Object form, provided that You
      meet the following conditions:

      (a) You must give any other recipients of the Work or
          Derivative Works a copy of this License; and

      (b) You must cause any modified files to carry prominent notices
          stating that You changed the files; and

      (c) You must retain, in the Source form of any Derivative Works
          that You distribute, all copyright, patent, trademark, and
          attribution notices from the Source form of the Work,
          excluding those notices that do not pertain to any part of
          the Derivative Works; and

      (d) If the Work includes a "NOTICE" text file as part of its
          distribution, then any Derivative Works that You distribute must
          include a readable copy of the attribution notices contained
          within such NOTICE file, excluding those notices that do not
          pertain to any part of the Derivative Works, in at least one
          of the following places: within a NOTICE text file distributed
          as part of the Derivative Works; within the Source form or
          documentation, if provided along with the Derivative Works; or,
          within a display generated by the Derivative Works, if and
          wherever such third-party notices normally appear. The contents
          of the NOTICE file are for informational purposes only and
          do not modify the License. You may add Your own attribution
          notices within Derivative Works that You distribute, alongside
          or as an addendum to the NOTICE text from the Work, provided
          that such additional attribution notices cannot be construed
          as modifying the License.

      You may add Your own copyright statement to Your modifications and
      may provide additional or different license terms and conditions
      for use, reproduction, or distribution of Your modifications, or
      for any such Derivative Works as a whole, provided Your use,
      reproduction, and distribution of the Work otherwise complies with
      the conditions stated in this License.

   5. Submission of Contributions. Unless You explicitly state otherwise,
      any Contribution intentionally submitted for inclusion in the Work
      by You to the Licensor shall be under the terms and conditions of
      this License, without any additional terms or conditions.
      Notwithstanding the above, nothing herein shall supersede or modify
      the terms of any separate license agreement you may have executed
      with Licensor regarding such Contributions.

   6. Trademarks. This License does not grant permission to use the trade
      names, trademarks, service marks, or product names of the Licensor,
      except as required for reasonable and customary use in describing the
      origin of the Work and reproducing the content of the NOTICE file.

   7. Disclaimer of Warranty. Unless required by applicable law or
      agreed to in writing, Licensor provides the Work (and each
      Contributor provides its Contributions) on an "AS IS" BASIS,
      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or

      "You" (or "Your") shall mean an individual or Legal Entity
      exercising permissions granted by this License.

      "Source" form shall mean the preferred form for making modifications,
      including but not limited to software source code, documentation
      source, and configuration files.

      "Object" form shall mean any form resulting from mechanical
      transformation or translation of a Source form, including but
      not limited to compiled object code, generated documentation,
      and conversions to other media types.

      "Work" shall mean the work of authorship, whether in Source or
      Object form, made available under the License, as indicated by a
      copyright notice that is included in or attached to the work
      (an example is provided in the Appendix below).

      "Derivative Works" shall mean any work, whether in Source or Object
      form, that is based on (or derived from) the Work and for which the
      editorial revisions, annotations, elaborations, or other modifications
      represent, as a whole, an original work of authorship. For the purposes
      of this License, Derivative Works shall not include works that remain
      separable from, or merely link (or bind by name) to the interfaces of,
      the Work and Derivative Works thereof.

      "Contribution" shall mean any work of authorship, including
      the original version of the Work and any modifications or additions
      to that Work or Derivative Works thereof, that is intentionally
      submitted to Licensor for inclusion in the Work by the copyright owner
      or by an individual or Legal Entity authorized to submit on behalf of
      the copyright owner. For the purposes of this definition, "submitted"
      means any form of electronic, verbal, or written communication sent
      to the Licensor or its representatives, including but not limited to
      communication on electronic mailing lists, source code control systems,
      and issue tracking systems that are managed by, or on behalf of, the
      Licensor for the purpose of discussing and improving the Work, but
      excluding communication that is conspicuously marked or otherwise
      designated in writing by the copyright owner as "Not a Contribution."

      "Contributor" shall mean Licensor and any individual or Legal Entity
      on behalf of whom a Contribution has been received by Licensor and
      subsequently incorporated within the Work.

   2. Grant of Copyright License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      copyright license to reproduce, prepare Derivative Works of,
      publicly display, publicly perform, sublicense, and distribute the
      Work and such Derivative Works in Source or Object form.

   3. Grant of Patent License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      (except as stated in this section) patent license to make, have made,
      use, offer to sell, sell, import, and otherwise transfer the Work,
      where such license applies only to those patent claims licensable
      by such Contributor that are necessarily infringed by their
      Contribution(s) alone or by combination of their Contribution(s)
      with the Work to which such Contribution(s) was submitted. If You
      institute patent litigation against any entity (including a
      cross-claim or counterclaim in a lawsuit) alleging that the Work
      or a Contribution incorporated within the Work constitutes direct
      or contributory patent infringement, then any patent licenses
      granted to You under this License for that Work shall terminate
      as of the date such litigation is filed.

   4. Redistribution. You may reproduce and distribute copies of the
      Work or Derivative Works thereof in any medium, with or without
      modifications, and in Source or Object form, provided that You
      meet the following conditions:

      (a) You must give any other recipients of the Work or
          Derivative Works a copy of this License; and

      (b) You must cause any modified files to carry prominent notices
          stating that You changed the files; and

      (c) You must retain, in the Source form of any Derivative Works
          that You distribute, all copyright, patent, trademark, and
          attribution notices from the Source form of the Work,
          excluding those notices that do not pertain to any part of
          the Derivative Works; and

      (d) If the Work includes a "NOTICE" text file as part of its
          distribution, then any Derivative Works that You distribute must
          include a readable copy of the attribution notices contained
          within such NOTICE file, excluding those notices that do not
          pertain to any part of the Derivative Works, in at least one
          of the following places: within a NOTICE text file distributed
          as part of the Derivative Works; within the Source form or
          documentation, if provided along with the Derivative Works; or,
          within a display generated by the Derivative Works, if and
          wherever such third-party notices normally appear. The contents
          of the NOTICE file are for informational purposes only and
          do not modify the License. You may add Your own attribution
          notices within Derivative Works that You distribute, alongside
          or as an addendum to the NOTICE text from the Work, provided
          that such additional attribution notices cannot be construed
          as modifying the License.

      You may add Your own copyright statement to Your modifications and
      may provide additional or different license terms and conditions
      for use, reproduction, or distribution of Your modifications, or
      for any such Derivative Works as a whole, provided Your use,
      reproduction, and distribution of the Work otherwise complies with
      the conditions stated in this License.

   5. Submission of Contributions. Unless You explicitly state otherwise,
      any Contribution intentionally submitted for inclusion in the Work
      by You to the Licensor shall be under the terms and conditions of
      this License, without any additional terms or conditions.
      Notwithstanding the above, nothing herein shall supersede or modify
      the terms of any separate license agreement you may have executed
      with Licensor regarding such Contributions.

   6. Trademarks. This License does not grant permission to use the trade
      names, trademarks, service marks, or product names of the Licensor,
      except as required for reasonable and customary use in describing the
      origin of the Work and reproducing the content of the NOTICE file.

   7. Disclaimer of Warranty. Unless required by applicable law or
      agreed to in writing, Licensor provides the Work (and each
      Contributor provides its Contributions) on an "AS IS" BASIS,
      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
      implied, including, without limitation, any warranties or conditions
      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
      PARTICULAR PURPOSE. You are solely responsible for determining the
      appropriateness of using or redistributing the Work and assume any
      risks associated with Your exercise of permissions under this License.

   8. Limitation of Liability. In no event and under no legal theory,
      whether in tort (including negligence), contract, or otherwise,
      unless required by applicable law (such as deliberate and grossly
      negligent acts) or agreed to in writing, shall any Contributor be
      liable to You for damages, including any direct, indirect, special,
      incidental, or consequential damages of any character arising as a
      result of this License or out of the use or inability to use the
      Work (including but not limited to damages for loss of goodwill,
      work stoppage, computer failure or malfunction, or any and all
      other commercial damages or losses), even if such Contributor
      has been advised of the possibility of such damages.

   9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
      of your accepting any such warranty or additional liability.

   END OF TERMS AND CONDITIONS

   APPENDIX: How to apply the Apache License to your work.

      To apply the Apache License to your work, attach the following
      boilerplate notice, with the fields enclosed by brackets "[]"
      replaced with your own identifying information. (Don't include
      the brackets!)  The text should be enclosed in the appropriate
      comment syntax for the file format. We also recommend that a
      file or class name and description of purpose be included on the
      same "printed page" as the copyright notice for easier
      identification within third-party archives.

      other entities that control, are controlled by, or are under common
      control with that entity. For the purposes of this definition,

      "You" (or "Your") shall mean an individual or Legal Entity
      exercising permissions granted by this License.

      "Source" form shall mean the preferred form for making modifications,
      including but not limited to software source code, documentation
      source, and configuration files.

      "Object" form shall mean any form resulting from mechanical
      transformation or translation of a Source form, including but
      not limited to compiled object code, generated documentation,
      and conversions to other media types.

      "Work" shall mean the work of authorship, whether in Source or
      Object form, made available under the License, as indicated by a
      copyright notice that is included in or attached to the work
      (an example is provided in the Appendix below).

      "Derivative Works" shall mean any work, whether in Source or Object
      form, that is based on (or derived from) the Work and for which the
      editorial revisions, annotations, elaborations, or other modifications
      represent, as a whole, an original work of authorship. For the purposes
      of this License, Derivative Works shall not include works that remain
      separable from, or merely link (or bind by name) to the interfaces of,
      the Work and Derivative Works thereof.

      "Contribution" shall mean any work of authorship, including
      the original version of the Work and any modifications or additions
      to that Work or Derivative Works thereof, that is intentionally
      submitted to Licensor for inclusion in the Work by the copyright owner
      or by an individual or Legal Entity authorized to submit on behalf of
      the copyright owner. For the purposes of this definition, "submitted"
      means any form of electronic, verbal, or written communication sent
      to the Licensor or its representatives, including but not limited to
      communication on electronic mailing lists, source code control systems,
      and issue tracking systems that are managed by, or on behalf of, the
      Licensor for the purpose of discussing and improving the Work, but
      excluding communication that is conspicuously marked or otherwise
      designated in writing by the copyright owner as "Not a Contribution."

      "Contributor" shall mean Licensor and any individual or Legal Entity
      on behalf of whom a Contribution has been received by Licensor and
      subsequently incorporated within the Work.

   2. Grant of Copyright License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      copyright license to reproduce, prepare Derivative Works of,
      publicly display, publicly perform, sublicense, and distribute the
      Work and such Derivative Works in Source or Object form.

   3. Grant of Patent License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      (except as stated in this section) patent license to make, have made,
      use, offer to sell, sell, import, and otherwise transfer the Work,
      where such license applies only to those patent claims licensable
      by such Contributor that are necessarily infringed by their
      Contribution(s) alone or by combination of their Contribution(s)
      with the Work to which such Contribution(s) was submitted. If You
      institute patent litigation against any entity (including a
      cross-claim or counterclaim in a lawsuit) alleging that the Work
      or a Contribution incorporated within the Work constitutes direct
      or contributory patent infringement, then any patent licenses
      granted to You under this License for that Work shall terminate
      as of the date such litigation is filed.

   4. Redistribution. You may reproduce and distribute copies of the
      Work or Derivative Works thereof in any medium, with or without
      modifications, and in Source or Object form, provided that You
      meet the following conditions:

      (a) You must give any other recipients of the Work or
          Derivative Works a copy of this License; and

      (b) You must cause any modified files to carry prominent notices
          stating that You changed the files; and

      (c) You must retain, in the Source form of any Derivative Works
          that You distribute, all copyright, patent, trademark, and
          attribution notices from the Source form of the Work,
          excluding those notices that do not pertain to any part of
          the Derivative Works; and

      (d) If the Work includes a "NOTICE" text file as part of its
          distribution, then any Derivative Works that You distribute must
          include a readable copy of the attribution notices contained
          within such NOTICE file, excluding those notices that do not
          pertain to any part of the Derivative Works, in at least one
          of the following places: within a NOTICE text file distributed
          as part of the Derivative Works; within the Source form or
          documentation, if provided along with the Derivative Works; or,
          within a display generated by the Derivative Works, if and
          wherever such third-party notices normally appear. The contents
          of the NOTICE file are for informational purposes only and
          do not modify the License. You may add Your own attribution
          notices within Derivative Works that You distribute, alongside
          or as an addendum to the NOTICE text from the Work, provided
          that such additional attribution notices cannot be construed
          as modifying the License.

      You may add Your own copyright statement to Your modifications and
      may provide additional or different license terms and conditions
      for use, reproduction, or distribution of Your modifications, or
      for any such Derivative Works as a whole, provided Your use,
      reproduction, and distribution of the Work otherwise complies with
      the conditions stated in this License.

   5. Submission of Contributions. Unless You explicitly state otherwise,
      any Contribution intentionally submitted for inclusion in the Work
      by You to the Licensor shall be under the terms and conditions of
      this License, without any additional terms or conditions.
      Notwithstanding the above, nothing herein shall supersede or modify
      the terms of any separate license agreement you may have executed
      with Licensor regarding such Contributions.

   6. Trademarks. This License does not grant permission to use the trade
      names, trademarks, service marks, or product names of the Licensor,
      except as required for reasonable and customary use in describing the
      origin of the Work and reproducing the content of the NOTICE file.

   7. Disclaimer of Warranty. Unless required by applicable law or
      agreed to in writing, Licensor provides the Work (and each
      Contributor provides its Contributions) on an "AS IS" BASIS,
      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
      implied, including, without limitation, any warranties or conditions
      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
      PARTICULAR PURPOSE. You are solely responsible for determining the
      appropriateness of using or redistributing the Work and assume any
      risks associated with Your exercise of permissions under this License.

   8. Limitation of Liability. In no event and under no legal theory,
      whether in tort (including negligence), contract, or otherwise,
      unless required by applicable law (such as deliberate and grossly
      negligent acts) or agreed to in writing, shall any Contributor be
      liable to You for damages, including any direct, indirect, special,
      incidental, or consequential damages of any character arising as a
      result of this License or out of the use or inability to use the
      Work (including but not limited to damages for loss of goodwill,
      work stoppage, computer failure or malfunction, or any and all
      other commercial damages or losses), even if such Contributor
      has been advised of the possibility of such damages.

   9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
      of your accepting any such warranty or additional liability.

      "License" shall mean the terms and conditions for use, reproduction,
      and distribution as defined by Sections 1 through 9 of this document.

      "Licensor" shall mean the copyright owner or entity authorized by
      the copyright owner that is granting the License.

      "Legal Entity" shall mean the union of the acting entity and all
      other entities that control, are controlled by, or are under common
      control with that entity. For the purposes of this definition,
      "control" means (i) the power, direct or indirect, to cause the
      direction or management of such entity, whether by contract or
      otherwise, or (ii) ownership of fifty percent (50%) or more of the
      outstanding shares, or (iii) beneficial ownership of such entity.

      "You" (or "Your") shall mean an individual or Legal Entity
      exercising permissions granted by this License.

      "Source" form shall mean the preferred form for making modifications,
      including but not limited to software source code, documentation
      source, and configuration files.

      "Object" form shall mean any form resulting from mechanical
      transformation or translation of a Source form, including but
      not limited to compiled object code, generated documentation,
      and conversions to other media types.

      "Work" shall mean the work of authorship, whether in Source or
      Object form, made available under the License, as indicated by a
      copyright notice that is included in or attached to the work
      (an example is provided in the Appendix below).

      "Derivative Works" shall mean any work, whether in Source or Object
      form, that is based on (or derived from) the Work and for which the
      editorial revisions, annotations, elaborations, or other modifications
      represent, as a whole, an original work of authorship. For the purposes
      of this License, Derivative Works shall not include works that remain
      separable from, or merely link (or bind by name) to the interfaces of,
      the Work and Derivative Works thereof.

      "Contribution" shall mean any work of authorship, including
      the original version of the Work and any modifications or additions
      to that Work or Derivative Works thereof, that is intentionally
      submitted to Licensor for inclusion in the Work by the copyright owner
      or by an individual or Legal Entity authorized to submit on behalf of
      the copyright owner. For the purposes of this definition, "submitted"
      means any form of electronic, verbal, or written communication sent
      to the Licensor or its representatives, including but not limited to
      communication on electronic mailing lists, source code control systems,
      and issue tracking systems that are managed by, or on behalf of, the
      Licensor for the purpose of discussing and improving the Work, but
      excluding communication that is conspicuously marked or otherwise
      designated in writing by the copyright owner as "Not a Contribution."

      "Contributor" shall mean Licensor and any individual or Legal Entity
      on behalf of whom a Contribution has been received by Licensor and
      subsequently incorporated within the Work.

   2. Grant of Copyright License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      copyright license to reproduce, prepare Derivative Works of,
      publicly display, publicly perform, sublicense, and distribute the
      Work and such Derivative Works in Source or Object form.

   3. Grant of Patent License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      (except as stated in this section) patent license to make, have made,
      use, offer to sell, sell, import, and otherwise transfer the Work,
      where such license applies only to those patent claims licensable
      by such Contributor that are necessarily infringed by their
      Contribution(s) alone or by combination of their Contribution(s)
      with the Work to which such Contribution(s) was submitted. If You
      institute patent litigation against any entity (including a
      cross-claim or counterclaim in a lawsuit) alleging that the Work
      or a Contribution incorporated within the Work constitutes direct
      or contributory patent infringement, then any patent licenses
      granted to You under this License for that Work shall terminate
      as of the date such litigation is filed.

   4. Redistribution. You may reproduce and distribute copies of the
      Work or Derivative Works thereof in any medium, with or without
      modifications, and in Source or Object form, provided that You
      meet the following conditions:

      (a) You must give any other recipients of the Work or
          Derivative Works a copy of this License; and

      (b) You must cause any modified files to carry prominent notices
          stating that You changed the files; and

      (c) You must retain, in the Source form of any Derivative Works
          that You distribute, all copyright, patent, trademark, and
          attribution notices from the Source form of the Work,
          excluding those notices that do not pertain to any part of
          the Derivative Works; and

      (d) If the Work includes a "NOTICE" text file as part of its
          distribution, then any Derivative Works that You distribute must
          include a readable copy of the attribution notices contained
          within such NOTICE file, excluding those notices that do not
          pertain to any part of the Derivative Works, in at least one
          of the following places: within a NOTICE text file distributed
          as part of the Derivative Works; within the Source form or
          documentation, if provided along with the Derivative Works; or,
          within a display generated by the Derivative Works, if and
          wherever such third-party notices normally appear. The contents
          of the NOTICE file are for informational purposes only and
          do not modify the License. You may add Your own attribution
          notices within Derivative Works that You distribute, alongside
          or as an addendum to the NOTICE text from the Work, provided
          that such additional attribution notices cannot be construed
          as modifying the License.

      You may add Your own copyright statement to Your modifications and
      may provide additional or different license terms and conditions
      for use, reproduction, or distribution of Your modifications, or
      for any such Derivative Works as a whole, provided Your use,
      reproduction, and distribution of the Work otherwise complies with
      the conditions stated in this License.

   5. Submission of Contributions. Unless You explicitly state otherwise,
      any Contribution intentionally submitted for inclusion in the Work
      by You to the Licensor shall be under the terms and conditions of
      this License, without any additional terms or conditions.
      Notwithstanding the above, nothing herein shall supersede or modify
      the terms of any separate license agreement you may have executed
      with Licensor regarding such Contributions.

   6. Trademarks. This License does not grant permission to use the trade
      names, trademarks, service marks, or product names of the Licensor,
      except as required for reasonable and customary use in describing the
      origin of the Work and reproducing the content of the NOTICE file.

   7. Disclaimer of Warranty. Unless required by applicable law or
      agreed to in writing, Licensor provides the Work (and each
      Contributor provides its Contributions) on an "AS IS" BASIS,
      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
      implied, including, without limitation, any warranties or conditions
      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
      PARTICULAR PURPOSE. You are solely responsible for determining the
      appropriateness of using or redistributing the Work and assume any
      risks associated with Your exercise of permissions under this License.

   8. Limitation of Liability. In no event and under no legal theory,
      whether in tort (including negligence), contract, or otherwise,
      unless required by applicable law (such as deliberate and grossly
      negligent acts) or agreed to in writing, shall any Contributor be
      liable to You for damages, including any direct, indirect, special,
      incidental, or consequential damages of any character arising as a
      result of this License or out of the use or inability to use the
      Work (including but not limited to damages for loss of goodwill,
      work stoppage, computer failure or malfunction, or any and all
      other commercial damages or losses), even if such Contributor
      has been advised of the possibility of such damages.

   9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
      of your accepting any such warranty or additional liability.

   END OF TERMS AND CONDITIONS

   APPENDIX: How to apply the Apache License to your work.

      To apply the Apache License to your work, attach the following
      boilerplate notice, with the fields enclosed by brackets "[]"
      replaced with your own identifying information. (Don't include
      the brackets!)  The text should be enclosed in the appropriate
      comment syntax for the file format. We also recommend that a
      file or class name and description of purpose be included on the

/***
 * A container for signed TUF metadata.
 *
 * Provides methods to convert to and from json, read and write to and
 * from JSON and to create and verify metadata signatures.
 *
 * ``Metadata[T]`` is a generic container type where T can be any one type of
 * [``Root``, ``Timestamp``, ``Snapshot``, ``Targets``]. The purpose of this
 * is to allow static type checking of the signed attribute in code using
 * Metadata::
 *
 * root_md = Metadata[Root].fromJSON("root.json")
 * # root_md type is now Metadata[Root]. This means signed and its
 * # attributes like consistent_snapshot are now statically typed and the
 * # types can be verified by static type checkers and shown by IDEs
 *
 * Using a type constraint is not required but not doing so means T is not a
 * specific type so static typing cannot happen. Note that the type constraint
 * ``[Root]`` is not validated at runtime (as pure annotations are not available
 * then).
 *
 * Apart from ``expires`` all of the arguments to the inner constructors have
 * reasonable default values for new metadata.

# mkdirp

Like `mkdir -p`, but in Node.js!

Now with a modern API and no\* bugs!

<small>\* may contain some bugs</small>

# example

## pow.js

```js
// hybrid module, import or require() both work
import { mkdirp } from 'mkdirp'
// or:
const { mkdirp } = require('mkdirp')

// return value is a Promise resolving to the first directory created
mkdirp('/tmp/foo/bar/baz').then(made =>
  console.log(`made directories, starting with ${made}`)
)
```

Output (where `/tmp/foo` already exists)

```
made directories, starting with /tmp/foo/bar
```

Or, if you don't have time to wait around for promises:

```js
import { mkdirp } from 'mkdirp'

// return value is the first directory created
const made = mkdirp.sync('/tmp/foo/bar/baz')
console.log(`made directories, starting with ${made}`)
```

And now /tmp/foo/bar/baz exists, huzzah!

# methods

```js
import { mkdirp } from 'mkdirp'
```

## `mkdirp(dir: string, opts?: MkdirpOptions) => Promise<string | undefined>`

Create a new directory and any necessary subdirectories at `dir`
with octal permission string `opts.mode`. If `opts` is a string
or number, it will be treated as the `opts.mode`.

If `opts.mode` isn't specified, it defaults to `0o777`.

Promise resolves to first directory `made` that had to be
created, or `undefined` if everything already exists. Promise
rejects if any errors are encountered. Note that, in the case of
promise rejection, some directories _may_ have been created, as
recursive directory creation is not an atomic operation.

You can optionally pass in an alternate `fs` implementation by
passing in `opts.fs`. Your implementation should have
`opts.fs.mkdir(path, opts, cb)` and `opts.fs.stat(path, cb)`.

You can also override just one or the other of `mkdir` and `stat`
by passing in `opts.stat` or `opts.mkdir`, or providing an `fs`
option that only overrides one of these.

## `mkdirp.sync(dir: string, opts: MkdirpOptions) => string|undefined`

Synchronously create a new directory and any necessary
subdirectories at `dir` with octal permission string `opts.mode`.
If `opts` is a string or number, it will be treated as the
`opts.mode`.

If `opts.mode` isn't specified, it defaults to `0o777`.

Returns the first directory that had to be created, or undefined
if everything already exists.

You can optionally pass in an alternate `fs` implementation by
passing in `opts.fs`. Your implementation should have
`opts.fs.mkdirSync(path, mode)` and `opts.fs.statSync(path)`.

You can also override just one or the other of `mkdirSync` and
`statSync` by passing in `opts.statSync` or `opts.mkdirSync`, or
providing an `fs` option that only overrides one of these.

## `mkdirp.manual`, `mkdirp.manualSync`

Use the manual implementation (not the native one). This is the
default when the native implementation is not available or the
stat/mkdir implementation is overridden.

## `mkdirp.native`, `mkdirp.nativeSync`

Use the native implementation (not the manual one). This is the
default when the native implementation is available and
stat/mkdir are not overridden.

# implementation

On Node.js v10.12.0 and above, use the native `fs.mkdir(p,
{recursive:true})` option, unless `fs.mkdir`/`fs.mkdirSync` has
been overridden by an option.

## native implementation

- If the path is a root directory, then pass it to the underlying
  implementation and return the result/error. (In this case,
  it'll either succeed or fail, but we aren't actually creating
  any dirs.)
- Walk up the path statting each directory, to find the first
  path that will be created, `made`.
- Call `fs.mkdir(path, { recursive: true })` (or `fs.mkdirSync`)
- If error, raise it to the caller.
- Return `made`.

## manual implementation

- Call underlying `fs.mkdir` implementation, with `recursive:
false`
- If error:
  - If path is a root directory, raise to the caller and do not
    handle it
  - If ENOENT, mkdirp parent dir, store result as `made`
  - stat(path)
    - If error, raise original `mkdir` error
    - If directory, return `made`
    - Else, raise original `mkdir` error
- else
  - return `undefined` if a root dir, or `made` if set, or `path`

## windows vs unix caveat

On Windows file systems, attempts to create a root directory (ie,
a drive letter or root UNC path) will fail. If the root
directory exists, then it will fail with `EPERM`. If the root
directory does not exist, then it will fail with `ENOENT`.

On posix file systems, attempts to create a root directory (in
recursive mode) will succeed silently, as it is treated like just
another directory that already exists. (In non-recursive mode,
of course, it fails with `EEXIST`.)

In order to preserve this system-specific behavior (and because
it's not as if we can create the parent of a root directory
anyway), attempts to create a root directory are passed directly
to the `fs` implementation, and any errors encountered are not
handled.

## native error caveat

The native implementation (as of at least Node.js v13.4.0) does
not provide appropriate errors in some cases (see
[nodejs/node#31481](https://github.com/nodejs/node/issues/31481)
and
[nodejs/node#28015](https://github.com/nodejs/node/issues/28015)).

In order to work around this issue, the native implementation
will fall back to the manual implementation if an `ENOENT` error
is encountered.

# choosing a recursive mkdir implementation

There are a few to choose from! Use the one that suits your
needs best :D

## use `fs.mkdir(path, {recursive: true}, cb)` if:

- You wish to optimize performance even at the expense of other
  factors.
- You don't need to know the first dir created.
- You are ok with getting `ENOENT` as the error when some other
  problem is the actual cause.
- You can limit your platforms to Node.js v10.12 and above.
- You're ok with using callbacks instead of promises.
- You don't need/want a CLI.
- You don't need to override the `fs` methods in use.

## use this module (mkdirp 1.x or 2.x) if:

- You need to know the first directory that was created.
- You wish to use the native implementation if available, but
  fall back when it's not.
- You prefer promise-returning APIs to callback-taking APIs.
- You want more useful error messages than the native recursive
  mkdir provides (at least as of Node.js v13.4), and are ok with
  re-trying on `ENOENT` to achieve this.
- You need (or at least, are ok with) a CLI.
- You need to override the `fs` methods in use.

## use [`make-dir`](http://npm.im/make-dir) if:

- You do not need to know the first dir created (and wish to save
  a few `stat` calls when using the native implementation for
  this reason).
- You wish to use the native implementation if available, but
  fall back when it's not.
- You prefer promise-returning APIs to callback-taking APIs.
- You are ok with occasionally getting `ENOENT` errors for
  failures that are actually related to something other than a
  missing file system entry.
- You don't need/want a CLI.
- You need to override the `fs` methods in use.

## use mkdirp 0.x if:

- You need to know the first directory that was created.
- You need (or at least, are ok with) a CLI.
- You need to override the `fs` methods in use.
- You're ok with using callbacks instead of promises.
- You are not running on Windows, where the root-level ENOENT
  errors can lead to infinite regress.
- You think vinyl just sounds warmer and richer for some weird
  reason.
- You are supporting truly ancient Node.js versions, before even
  the advent of a `Promise` language primitive. (Please don't.
  You deserve better.)

# cli

This package also ships with a `mkdirp` command.

```
$ mkdirp -h

usage: mkdirp [DIR1,DIR2..] {OPTIONS}

  Create each supplied directory including any necessary parent directories
  that don't yet exist.

  If the directory already exists, do nothing.

OPTIONS are:

  -m<mode>       If a directory needs to be created, set the mode as an octal
  --mode=<mode>  permission string.

  -v --version   Print the mkdirp version number

  -h --help      Print this helpful banner

  -p --print     Print the first directories created for each path provided

  --manual       Use manual implementation, even if native is available
```

# install

With [npm](http://npmjs.org) do:

```
npm install mkdirp
```

to get the library locally, or

```
npm install -g mkdirp
```

to get the command everywhere, or

```
npx mkdirp ...
```

to run the command without installing it globally.

# platform support

This module works on node v8, but only v10 and above are officially
supported, as Node v8 reached its LTS end of life 2020-01-01, which is in
the past, as of this writing.

# which

Like the unix `which` utility.

Finds the first instance of a specified executable in the PATH
environment variable.  Does not cache the results, so `hash -r` is not
needed when the PATH changes.

## USAGE

```javascript
var which = require('which')

// async usage
which('node', function (er, resolvedPath) {
  // er is returned if no "node" is found on the PATH
  // if it is found, then the absolute path to the exec is returned
})

// or promise
which('node').then(resolvedPath => { ... }).catch(er => { ... not found ... })

// sync usage
// throws if not found
var resolved = which.sync('node')

// if nothrow option is used, returns null if not found
resolved = which.sync('node', {nothrow: true})

// Pass options to override the PATH and PATHEXT environment vars.
which('node', { path: someOtherPath }, function (er, resolved) {
  if (er)
    throw er
  console.log('found at %j', resolved)
})
```

## CLI USAGE

Same as the BSD `which(1)` binary.

```
usage: which [-as] program ...
```

## OPTIONS

You may pass an options object as the second argument.

- `path`: Use instead of the `PATH` environment variable.
- `pathExt`: Use instead of the `PATHEXT` environment variable.
- `all`: Return all matches, instead of just the first one.  Note that
  this means the function returns an array of strings instead of a
  single string.
#!/usr/bin/env node
var which = require("../")
if (process.argv.length < 3)
  usage()

function usage () {
  console.error('usage: which [-as] program ...')
  process.exit(1)
}

var all = false
var silent = false

# cssesc [![Build status](https://travis-ci.org/mathiasbynens/cssesc.svg?branch=master)](https://travis-ci.org/mathiasbynens/cssesc) [![Code coverage status](https://img.shields.io/codecov/c/github/mathiasbynens/cssesc.svg)](https://codecov.io/gh/mathiasbynens/cssesc)

A JavaScript library for escaping CSS strings and identifiers while generating the shortest possible ASCII-only output.

This is a JavaScript library for [escaping text for use in CSS strings or identifiers](https://mathiasbynens.be/notes/css-escapes) while generating the shortest possible valid ASCII-only output. [Here’s an online demo.](https://mothereff.in/css-escapes)

[A polyfill for the CSSOM `CSS.escape()` method is available in a separate repository.](https://mths.be/cssescape) (In comparison, _cssesc_ is much more powerful.)

Feel free to fork if you see possible improvements!

## Installation

Via [npm](https://www.npmjs.com/):

```bash
npm install cssesc
```

In a browser:

```html
<script src="cssesc.js"></script>
```

In [Node.js](https://nodejs.org/):

```js
const cssesc = require('cssesc');
```

In Ruby using [the `ruby-cssesc` wrapper gem](https://github.com/borodean/ruby-cssesc):

```bash
gem install ruby-cssesc
```

```ruby
require 'ruby-cssesc'
CSSEsc.escape('I ♥ Ruby', is_identifier: true)
```

In Sass using [`sassy-escape`](https://github.com/borodean/sassy-escape):

```bash
gem install sassy-escape
```

```scss
body {
  content: escape('I ♥ Sass', $is-identifier: true);
}
```

## API

### `cssesc(value, options)`

This function takes a value and returns an escaped version of the value where any characters that are not printable ASCII symbols are escaped using the shortest possible (but valid) [escape sequences for use in CSS strings or identifiers](https://mathiasbynens.be/notes/css-escapes).

```js
cssesc('Ich ♥ Bücher');
// → 'Ich \\2665  B\\FC cher'

cssesc('foo 𝌆 bar');
// → 'foo \\1D306  bar'
```

By default, `cssesc` returns a string that can be used as part of a CSS string. If the target is a CSS identifier rather than a CSS string, use the `isIdentifier: true` setting (see below).

The optional `options` argument accepts an object with the following options:

#### `isIdentifier`

The default value for the `isIdentifier` option is `false`. This means that the input text will be escaped for use in a CSS string literal. If you want to use the result as a CSS identifier instead (in a selector, for example), set this option to `true`.

```js
cssesc('123a2b');
// → '123a2b'

cssesc('123a2b', {
  'isIdentifier': true
});
// → '\\31 23a2b'
```

#### `quotes`

The default value for the `quotes` option is `'single'`. This means that any occurences of `'` in the input text will be escaped as `\'`, so that the output can be used in a CSS string literal wrapped in single quotes.

```js
cssesc('Lorem ipsum "dolor" sit \'amet\' etc.');
// → 'Lorem ipsum "dolor" sit \\\'amet\\\' etc.'
// → "Lorem ipsum \"dolor\" sit \\'amet\\' etc."

cssesc('Lorem ipsum "dolor" sit \'amet\' etc.', {
  'quotes': 'single'
});
// → 'Lorem ipsum "dolor" sit \\\'amet\\\' etc.'
// → "Lorem ipsum \"dolor\" sit \\'amet\\' etc."
```

If you want to use the output as part of a CSS string literal wrapped in double quotes, set the `quotes` option to `'double'`.

```js
cssesc('Lorem ipsum "dolor" sit \'amet\' etc.', {
  'quotes': 'double'
});
// → 'Lorem ipsum \\"dolor\\" sit \'amet\' etc.'
// → "Lorem ipsum \\\"dolor\\\" sit 'amet' etc."
```

#### `wrap`

The `wrap` option takes a boolean value (`true` or `false`), and defaults to `false` (disabled). When enabled, the output will be a valid CSS string literal wrapped in quotes. The type of quotes can be specified through the `quotes` setting.

```js
cssesc('Lorem ipsum "dolor" sit \'amet\' etc.', {
  'quotes': 'single',
  'wrap': true
});
// → '\'Lorem ipsum "dolor" sit \\\'amet\\\' etc.\''
// → "\'Lorem ipsum \"dolor\" sit \\\'amet\\\' etc.\'"

cssesc('Lorem ipsum "dolor" sit \'amet\' etc.', {
  'quotes': 'double',
  'wrap': true
});
// → '"Lorem ipsum \\"dolor\\" sit \'amet\' etc."'
// → "\"Lorem ipsum \\\"dolor\\\" sit \'amet\' etc.\""
```

#### `escapeEverything`

The `escapeEverything` option takes a boolean value (`true` or `false`), and defaults to `false` (disabled). When enabled, all the symbols in the output will be escaped, even printable ASCII symbols.

```js
cssesc('lolwat"foo\'bar', {
  'escapeEverything': true
});
// → '\\6C\\6F\\6C\\77\\61\\74\\"\\66\\6F\\6F\\\'\\62\\61\\72'
// → "\\6C\\6F\\6C\\77\\61\\74\\\"\\66\\6F\\6F\\'\\62\\61\\72"
```

#### Overriding the default options globally

The global default settings can be overridden by modifying the `css.options` object. This saves you from passing in an `options` object for every call to `encode` if you want to use the non-default setting.

```js
// Read the global default setting for `escapeEverything`:
cssesc.options.escapeEverything;
// → `false` by default

// Override the global default setting for `escapeEverything`:
cssesc.options.escapeEverything = true;

// Using the global default setting for `escapeEverything`, which is now `true`:
cssesc('foo © bar ≠ baz 𝌆 qux');
// → '\\66\\6F\\6F\\ \\A9\\ \\62\\61\\72\\ \\2260\\ \\62\\61\\7A\\ \\1D306\\ \\71\\75\\78'
```

### `cssesc.version`

A string representing the semantic version number.

### Using the `cssesc` binary

To use the `cssesc` binary in your shell, simply install cssesc globally using npm:

```bash
npm install -g cssesc
```

After that you will be able to escape text for use in CSS strings or identifiers from the command line:

```bash
$ cssesc 'föo ♥ bår 𝌆 baz'
f\F6o \2665  b\E5r \1D306  baz
```

If the output needs to be a CSS identifier rather than part of a string literal, use the `-i`/`--identifier` option:

```bash
$ cssesc --identifier 'föo ♥ bår 𝌆 baz'
f\F6o\ \2665\ b\E5r\ \1D306\ baz
```

See `cssesc --help` for the full list of options.

## Support

This library supports the Node.js and browser versions mentioned in [`.babelrc`](https://github.com/mathiasbynens/cssesc/blob/master/.babelrc). For a version that supports a wider variety of legacy browsers and environments out-of-the-box, [see v0.1.0](https://github.com/mathiasbynens/cssesc/releases/tag/v0.1.0).

.Sh DESCRIPTION
.Nm
escapes strings for use in CSS string literals or identifiers while generating the shortest possible valid ASCII-only output.
.Sh OPTIONS
.Bl -ohang -offset
.It Sy "-s, --single-quotes"
Escape any occurences of ' in the input string as \\', so that the output can be used in a CSS string literal wrapped in single quotes.
.It Sy "-d, --double-quotes"
Escape any occurences of " in the input string as \\", so that the output can be used in a CSS string literal wrapped in double quotes.
.It Sy "-w, --wrap"
Make sure the output is a valid CSS string literal wrapped in quotes. The type of quotes can be specified using the
.Ar -s | --single-quotes
or
.Ar -d | --double-quotes
settings.
.It Sy "-e, --escape-everything"
Escape all the symbols in the output, even printable ASCII symbols.
.It Sy "-v, --version"
Print cssesc's version.
.It Sy "-h, --help"
Show the help screen.
.El
.Sh EXIT STATUS
The
.Nm cssesc
utility exits with one of the following values:
.Pp
.Bl -tag -width flag -compact
.It Li 0
.Nm
successfully escaped the given text and printed the result.
.It Li 1
.Nm
wasn't instructed to escape anything (for example, the
.Ar --help
flag was set); or, an error occurred.
.El
.Sh EXAMPLES
.Bl -ohang -offset
.It Sy "cssesc 'foo bar baz'"
Print an escaped version of the given text.
.It Sy echo\ 'foo bar baz'\ |\ cssesc
Print an escaped version of the text that gets piped in.

# How to Contribute

## Pull Requests

We also accept [pull requests][pull-request]!

Generally we like to see pull requests that

- Maintain the existing code style
- Are focused on a single change (i.e. avoid large refactoring or style adjustments in untouched code if not the primary goal of the pull request)
- Have [good commit messages](http://tbaggery.com/2008/04/19/a-note-about-git-commit-messages.html)
- Have tests
- Don't decrease the current code coverage (see coverage/lcov-report/index.html)

## Building

```
yarn
yarn test
```

Running `yarn test -- dev` will watch for tests within Node and `karma start` may be used for manual testing in browsers.

If you notice any problems, please report them to the GitHub issue tracker at
[http://github.com/kpdecker/jsdiff/issues](http://github.com/kpdecker/jsdiff/issues).

## Releasing

A full release may be completed by first updating the `"version"` property in package.json, then running the following:

```
yarn clean
yarn grunt release
yarn publish
```

After releasing, remember to:
* commit the `package.json` change and push it to GitHub
* create a new version tag on GitHub
* update `diff.js` on the `gh-pages` branch to the latest built version from the `dist/` folder.

  // We have to include surrounding whitespace in the tokens because the two

  // * If we just discard the whitespace, we can't fully reproduce the original
  //   text from the sequence of tokens and any attempt to render the diff will
  //   get the whitespace wrong.

  //   the optimal diff between two texts being a perverse one that preserves
  //   the spaces between words but deletes and reinserts actual common words.

// Each token is one of the following:
// - A punctuation mark plus the surrounding whitespace
// - A word plus the surrounding whitespace
// - Pure whitespace (but only in the special case where this the entire text
//   is just whitespace)
//
// We have to include surrounding whitespace in the tokens because the two
// alternative approaches produce horribly broken results:
// * If we just discard the whitespace, we can't fully reproduce the original
//   text from the sequence of tokens and any attempt to render the diff will
//   get the whitespace wrong.
// * If we have separate tokens for whitespace, then in a typical text every
//   second token will be a single space character. But this often results in
//   the optimal diff between two texts being a perverse one that preserves
//   the spaces between words but deletes and reinserts actual common words.
//   See https://github.com/kpdecker/jsdiff/issues/160#issuecomment-1866099640
//   for an example.
//
// Keeping the surrounding whitespace of course has implications for .equals
// and .join, not just .tokenize.

// This regex does NOT fully implement the tokenization rules described above.
// Instead, it gives runs of whitespace their own "token". The tokenize method
// then handles stitching whitespace tokens onto adjacent word or punctuation

  //    After cleanup, we want K:'foo ' D:'bar' I:'qux' K:' baz'
  //

  //    but don't actually manage this currently (the pre-cleanup change
  //    objects don't contain enough information to make it possible).
  //

  //    After cleanup, we want K:'foo  ' D:' bar ' K:'baz'

  // indel between keeps and the whitespace has changed. For instance, consider
  // diffing 'foo\tbar\nbaz' vs 'foo baz'. Unless we create an extra change
  // object to represent the insertion of the space character (which isn't even
  // a token), we have no way to avoid losing information about the texts'
  // original whitespace in the result we return. Still, we do our best to
  // output something that will look sensible if we e.g. print it with
  // insertions in green and deletions in red.

  // Between two "keep" change objects (or before the first or after the last
  // change object), we can have either:
  // * A "delete" followed by an "insert"
  // * Just an "insert"
  // * Just a "delete"
  // We handle the three cases separately.

// * If we just discard the whitespace, we can't fully reproduce the original
//   text from the sequence of tokens and any attempt to render the diff will

  // * Just a "delete"

// * If we just discard the whitespace, we can't fully reproduce the original
//   text from the sequence of tokens and any attempt to render the diff will

  // * Just a "delete"

# Release Notes

## 7.0.0

Just a single (breaking) bugfix, undoing a behaviour change introduced accidentally in 6.0.0:

- [#554](https://github.com/kpdecker/jsdiff/pull/554) **`diffWords` treats numbers and underscores as word characters again.** This behaviour was broken in v6.0.0.

## 6.0.0

This is a release containing many, *many* breaking changes. The objective of this release was to carry out a mass fix, in one go, of all the open bugs and design problems that required breaking changes to fix. A substantial, but exhaustive, changelog is below.

[Commits](https://github.com/kpdecker/jsdiff/compare/v5.2.0...v6.0.0)

- [#497](https://github.com/kpdecker/jsdiff/pull/497) **`diffWords` behavior has been radically changed.** Previously, even with `ignoreWhitespace: true`, runs of whitespace were tokens, which led to unhelpful and unintuitive diffing behavior in typical texts. Specifically, even when two texts contained overlapping passages, `diffWords` would sometimes choose to delete all the words from the old text and insert them anew in their new positions in order to avoid having to delete or insert whitespace tokens. Whitespace sequences are no longer tokens as of this release, which affects both the generated diffs and the `count`s.

  Runs of whitespace are still tokens in `diffWordsWithSpace`.

  As part of the changes to `diffWords`, **a new `.postProcess` method has been added on the base `Diff` type**, which can be overridden in custom `Diff` implementations.

  **`diffLines` with `ignoreWhitespace: true` will no longer ignore the insertion or deletion of entire extra lines of whitespace at the end of the text**. Previously, these would not show up as insertions or deletions, as a side effect of a hack in the base diffing algorithm meant to help ignore whitespace in `diffWords`. More generally, **the undocumented special handling in the core algorithm for ignored terminals has been removed entirely.** (This special case behavior used to rewrite the final two change objects in a scenario where the final change object was an addition or deletion and its `value` was treated as equal to the empty string when compared using the diff object's `.equals` method.)

- [#500](https://github.com/kpdecker/jsdiff/pull/500) **`diffChars` now diffs Unicode code points** instead of UTF-16 code units.
- [#508](https://github.com/kpdecker/jsdiff/pull/508) **`parsePatch` now always runs in what was previously "strict" mode; the undocumented `strict` option has been removed.** Previously, by default, `parsePatch` (and other patch functions that use it under the hood to parse patches) would accept a patch where the line counts in the headers were inconsistent with the actual patch content - e.g. where a hunk started with the header `@@ -1,3 +1,6 @@`, indicating that the content below spanned 3 lines in the old file and 6 lines in the new file, but then the actual content below the header consisted of some different number of lines, say 10 lines of context, 5 deletions, and 1 insertion. Actually trying to work with these patches using `applyPatch` or `merge`, however, would produce incorrect results instead of just ignoring the incorrect headers, making this "feature" more of a trap than something actually useful. It's been ripped out, and now we are always "strict" and will reject patches where the line counts in the headers aren't consistent with the actual patch content.
- [#435](https://github.com/kpdecker/jsdiff/pull/435) **Fix `parsePatch` handling of control characters.** `parsePatch` used to interpret various unusual control characters - namely vertical tabs, form feeds, lone carriage returns without a line feed, and EBCDIC NELs - as line breaks when parsing a patch file. This was inconsistent with the behavior of both JsDiff's own `diffLines` method and also the Unix `diff` and `patch` utils, which all simply treat those control characters as ordinary characters. The result of this discrepancy was that some well-formed patches - produced either by `diff` or by JsDiff itself and handled properly by the `patch` util - would be wrongly parsed by `parsePatch`, with the effect that it would disregard the remainder of a hunk after encountering one of these control characters.
- [#439](https://github.com/kpdecker/jsdiff/pull/439) **Prefer diffs that order deletions before insertions.** When faced with a choice between two diffs with an equal total edit distance, the Myers diff algorithm generally prefers one that does deletions before insertions rather than insertions before deletions. For instance, when diffing `abcd` against `acbd`, it will prefer a diff that says to delete the `b` and then insert a new `b` after the `c`, over a diff that says to insert a `c` before the `b` and then delete the existing `c`. JsDiff deviated from the published Myers algorithm in a way that led to it having the opposite preference in many cases, including that example. This is now fixed, meaning diffs output by JsDiff will more accurately reflect what the published Myers diff algorithm would output.
- [#455](https://github.com/kpdecker/jsdiff/pull/455) **The `added` and `removed` properties of change objects are now guaranteed to be set to a boolean value.** (Previously, they would be set to `undefined` or omitted entirely instead of setting them to false.)
- [#464](https://github.com/kpdecker/jsdiff/pull/464) Specifying `{maxEditLength: 0}` now sets a max edit length of 0 instead of no maximum.
- [#460](https://github.com/kpdecker/jsdiff/pull/460) **Added `oneChangePerToken` option.**
- [#467](https://github.com/kpdecker/jsdiff/pull/467) **Consistent ordering of arguments to `comparator(left, right)`.** Values from the old array will now consistently be passed as the first argument (`left`) and values from the new array as the second argument (`right`). Previously this was almost (but not quite) always the other way round.
- [#480](https://github.com/kpdecker/jsdiff/pull/480) **Passing `maxEditLength` to `createPatch` & `createTwoFilesPatch` now works properly** (i.e. returns undefined if the max edit distance is exceeded; previous behavior was to crash with a `TypeError` if the edit distance was exceeded).
- [#486](https://github.com/kpdecker/jsdiff/pull/486) **The `ignoreWhitespace` option of `diffLines` behaves more sensibly now.** `value`s in returned change objects now include leading/trailing whitespace even when `ignoreWhitespace` is used, just like how with `ignoreCase` the `value`s still reflect the case of one of the original texts instead of being all-lowercase. `ignoreWhitespace` is also now compatible with `newlineIsToken`. Finally, **`diffTrimmedLines` is deprecated** (and removed from the docs) in favour of using `diffLines` with `ignoreWhitespace: true`; the two are, and always have been, equivalent.
- [#490](https://github.com/kpdecker/jsdiff/pull/490) **When calling diffing functions in async mode by passing a `callback` option, the diff result will now be passed as the *first* argument to the callback instead of the second.** (Previously, the first argument was never used at all and would always have value `undefined`.)
- [#489](github.com/kpdecker/jsdiff/pull/489) **`this.options` no longer exists on `Diff` objects.** Instead, `options` is now passed as an argument to methods that rely on options, like `equals(left, right, options)`. This fixes a race condition in async mode, where diffing behaviour could be changed mid-execution if a concurrent usage of the same `Diff` instances overwrote its `options`.
- [#518](https://github.com/kpdecker/jsdiff/pull/518) **`linedelimiters` no longer exists** on patch objects; instead, when a patch with Windows-style CRLF line endings is parsed, **the lines in `lines` will end with `\r`**. There is now a **new `autoConvertLineEndings` option, on by default**, which makes it so that when a patch with Windows-style line endings is applied to a source file with Unix style line endings, the patch gets autoconverted to use Unix-style line endings, and when a patch with Unix-style line endings is applied to a source file with Windows-style line endings, it gets autoconverted to use Windows-style line endings.
- [#521](https://github.com/kpdecker/jsdiff/pull/521) **the `callback` option is now supported by `structuredPatch`, `createPatch
- [#529](https://github.com/kpdecker/jsdiff/pull/529) **`parsePatch` can now parse patches where lines starting with `--` or `++` are deleted/inserted**; previously, there were edge cases where the parser would choke on valid patches or give wrong results.
- [#530](https://github.com/kpdecker/jsdiff/pull/530) **Added `ignoreNewlineAtEof` option` to `diffLines`**
- [#533](https://github.com/kpdecker/jsdiff/pull/533) **`applyPatch` uses an entirely new algorithm for fuzzy matching.** Differences between the old and new algorithm are as follows:
  * The `fuzzFactor` now indicates the maximum [*Levenshtein* distance](https://en.wikipedia.org/wiki/Levenshtein_distance) that there can be between the context shown in a hunk and the actual file content at a location where we try to apply the hunk. (Previously, it represented a maximum [*Hamming* distance](https://en.wikipedia.org/wiki/Hamming_distance), meaning that a single insertion or deletion in the source file could stop a hunk from applying even with a high `fuzzFactor`.)
  * A hunk containing a deletion can now only be applied in a context where the line to be deleted actually appears verbatim. (Previously, as long as enough context lines in the hunk matched, `applyPatch` would apply the hunk anyway and delete a completely different line.)
  * The context line immediately before and immediately after an insertion must match exactly between the hunk and the file for a hunk to apply. (Previously this was not required.)
- [#535](https://github.com/kpdecker/jsdiff/pull/535) **A bug in patch generation functions is now fixed** that would sometimes previously cause `\ No newline at end of file` to appear in the wrong place in the generated patch, resulting in the patch being invalid.
- [#535](https://github.com/kpdecker/jsdiff/pull/535) **Passing `newlineIsToken: true` to *patch*-generation functions is no longer allowed.** (Passing it to `diffLines` is still supported - it's only functions like `createPatch` where passing `newlineIsToken` is now an error.) Allowing it to be passed never really made sense, since in cases where the option had any effect on the output at all, the effect tended to be causing a garbled patch to be created that couldn't actually be applied to the source file.
- [#539](https://github.com/kpdecker/jsdiff/pull/539) **`diffWords` now takes an optional `intlSegmenter` option** which should be an `Intl.Segmenter` with word-level granularity. This provides better tokenization of text into words than the default behaviour, even for English but especially for some other languages for which the default behaviour is poor.

## v5.2.0

[Commits](https://github.com/kpdecker/jsdiff/compare/v5.1.0...v5.2.0)

- [#411](https://github.com/kpdecker/jsdiff/pull/411) Big performance improvement. Previously an O(n) array-copying operation inside the innermost loop of jsdiff's base diffing code increased the overall worst-case time complexity of computing a diff from O(n²) to O(n³). This is now fixed, bringing the worst-case time complexity down to what it theoretically should be for a Myers diff implementation.
- [#448](https://github.com/kpdecker/jsdiff/pull/411) Performance improvement. Diagonals whose furthest-reaching D-path would go off the edge of the edit graph are now skipped, rather than being pointlessly considered as called for by the original Myers diff algorithm. This dramatically speeds up computing diffs where the new text just appends or truncates content at the end of the old text.
- [#351](https://github.com/kpdecker/jsdiff/issues/351) Importing from the lib folder - e.g. `require("diff/lib/diff/word.js")` - will work again now. This had been broken for users on the latest version of Node since Node 17.5.0, which changed how Node interprets the `exports` property in jsdiff's `package.json` file.
- [#344](https://github.com/kpdecker/jsdiff/issues/344) `diffLines`, `createTwoFilesPatch`, and other patch-creation methods now take an optional `stripTrailingCr: true` option which causes Windows-style `\r\n` line endings to be replaced with Unix-style `\n` line endings before calculating the diff, just like GNU `diff`'s `--strip-trailing-cr` flag.
- [#451](https://github.com/kpdecker/jsdiff/pull/451) Added `diff.formatPatch`.
- [#450](https://github.com/kpdecker/jsdiff/pull/450) Added `diff.reversePatch`.
- [#478](https://github.com/kpdecker/jsdiff/pull/478) Added `timeout` option.

- The library has been refactored to use some ES6 features. The external APIs should remain the same, but bower projects that directly referenced the repository will now have to point to the [components/jsdiff](https://github.com/components/jsdiff) repository.

      exercising permissions granted by this License.

      "Source" form shall mean the preferred form for making modifications,
      including but not limited to software source code, documentation
      source, and configuration files.

      "Object" form shall mean any form resulting from mechanical
      transformation or translation of a Source form, including but
      not limited to compiled object code, generated documentation,

      "Work" shall mean the work of authorship, whether in Source or
      Object form, made available under the License, as indicated by a
      copyright notice that is included in or attached to the work
      (an example is provided in the Appendix below).

      "Derivative Works" shall mean any work, whether in Source or Object
      form, that is based on (or derived from) the Work and for which the
      editorial revisions, annotations, elaborations, or other modifications
      represent, as a whole, an original work of authorship. For the purposes
      of this License, Derivative Works shall not include works that remain

      the Work and Derivative Works thereof.

      "Contribution" shall mean any work of authorship, including

      or by an individual or Legal Entity authorized to submit on behalf of
      the copyright owner. For the purposes of this definition, "submitted"
      means any form of electronic, verbal, or written communication sent

      designated in writing by the copyright owner as "Not a Contribution."

      "Contributor" shall mean Licensor and any individual or Legal Entity
      on behalf of whom a Contribution has been received by Licensor and

   2. Grant of Copyright License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      copyright license to reproduce, prepare Derivative Works of,
      publicly display, publicly perform, sublicense, and distribute the
      Work and such Derivative Works in Source or Object form.

   3. Grant of Patent License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      (except as stated in this section) patent license to make, have made,
      use, offer to sell, sell, import, and otherwise transfer the Work,
      where such license applies only to those patent claims licensable
      by such Contributor that are necessarily infringed by their
      Contribution(s) alone or by combination of their Contribution(s)
      with the Work to which such Contribution(s) was submitted. If You
      institute patent litigation against any entity (including a
      cross-claim or counterclaim in a lawsuit) alleging that the Work
      or a Contribution incorporated within the Work constitutes direct
      or contributory patent infringement, then any patent licenses
      granted to You under this License for that Work shall terminate
      as of the date such litigation is filed.

   4. Redistribution. You may reproduce and distribute copies of the
      Work or Derivative Works thereof in any medium, with or without
      modifications, and in Source or Object form, provided that You
      meet the following conditions:

      (a) You must give any other recipients of the Work or
          Derivative Works a copy of this License; and

      (b) You must cause any modified files to carry prominent notices
          stating that You changed the files; and

      (c) You must retain, in the Source form of any Derivative Works
          that You distribute, all copyright, patent, trademark, and
          attribution notices from the Source form of the Work,
          excluding those notices that do not pertain to any part of
          the Derivative Works; and

      (d) If the Work includes a "NOTICE" text file as part of its
          distribution, then any Derivative Works that You distribute must
          include a readable copy of the attribution notices contained
          within such NOTICE file, excluding those notices that do not
          pertain to any part of the Derivative Works, in at least one
          of the following places: within a NOTICE text file distributed
          as part of the Derivative Works; within the Source form or
          documentation, if provided along with the Derivative Works; or,
          within a display generated by the Derivative Works, if and
          wherever such third-party notices normally appear. The contents
          of the NOTICE file are for informational purposes only and
          do not modify the License. You may add Your own attribution
          notices within Derivative Works that You distribute, alongside
          or as an addendum to the NOTICE text from the Work, provided
          that such additional attribution notices cannot be construed
          as modifying the License.

      You may add Your own copyright statement to Your modifications and
      may provide additional or different license terms and conditions
      for use, reproduction, or distribution of Your modifications, or
      for any such Derivative Works as a whole, provided Your use,
      reproduction, and distribution of the Work otherwise complies with
      the conditions stated in this License.

   5. Submission of Contributions. Unless You explicitly state otherwise,
      any Contribution intentionally submitted for inclusion in the Work
      by You to the Licensor shall be under the terms and conditions of
      this License, without any additional terms or conditions.
      Notwithstanding the above, nothing herein shall supersede or modify
      the terms of any separate license agreement you may have executed
      with Licensor regarding such Contributions.

   6. Trademarks. This License does not grant permission to use the trade
      names, trademarks, service marks, or product names of the Licensor,
      except as required for reasonable and customary use in describing the
      origin of the Work and reproducing the content of the NOTICE file.

   7. Disclaimer of Warranty. Unless required by applicable law or
      agreed to in writing, Licensor provides the Work (and each
      Contributor provides its Contributions) on an "AS IS" BASIS,
      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
      implied, including, without limitation, any warranties or conditions
      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
      PARTICULAR PURPOSE. You are solely responsible for determining the
      appropriateness of using or redistributing the Work and assume any
      risks associated with Your exercise of permissions under this License.

   8. Limitation of Liability. In no event and under no legal theory,
      whether in tort (including negligence), contract, or otherwise,
      unless required by applicable law (such as deliberate and grossly
      negligent acts) or agreed to in writing, shall any Contributor be
      liable to You for damages, including any direct, indirect, special,
      incidental, or consequential damages of any character arising as a
      result of this License or out of the use or inability to use the
      Work (including but not limited to damages for loss of goodwill,
      work stoppage, computer failure or malfunction, or any and all
      other commercial damages or losses), even if such Contributor
      has been advised of the possibility of such damages.

   9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
      of your accepting any such warranty or additional liability.

# Glob

Match files using the patterns the shell uses.

The most correct and second fastest glob implementation in
JavaScript. (See **Comparison to Other JavaScript Glob
Implementations** at the bottom of this readme.)

![a fun cartoon logo made of glob characters](https://github.com/isaacs/node-glob/raw/main/logo/glob.png)

## Usage

Install with npm

```
npm i glob
```

**Note** the npm package name is _not_ `node-glob` that's a
different thing that was abandoned years ago. Just `glob`.

```js
// load using import
import { glob, globSync, globStream, globStreamSync, Glob } from 'glob'
// or using commonjs, that's fine, too
const {
  glob,
  globSync,
  globStream,
  globStreamSync,
  Glob,
} = require('glob')

// the main glob() and globSync() resolve/return array of filenames

// all js files, but don't look in node_modules
const jsfiles = await glob('**/*.js', { ignore: 'node_modules/**' })

// pass in a signal to cancel the glob walk
const stopAfter100ms = await glob('**/*.css', {
  signal: AbortSignal.timeout(100),
})

// multiple patterns supported as well
const images = await glob(['css/*.{png,jpeg}', 'public/*.{png,jpeg}'])

// but of course you can do that with the glob pattern also
// the sync function is the same, just returns a string[] instead
// of Promise<string[]>
const imagesAlt = globSync('{css,public}/*.{png,jpeg}')

// you can also stream them, this is a Minipass stream
const filesStream = globStream(['**/*.dat', 'logs/**/*.log'])

// construct a Glob object if you wanna do it that way, which
// allows for much faster walks if you have to look in the same
// folder multiple times.
const g = new Glob('**/foo', {})
// glob objects are async iterators, can also do globIterate() or
// g.iterate(), same deal
for await (const file of g) {
  console.log('found a foo file:', file)
}
// pass a glob as the glob options to reuse its settings and caches
const g2 = new Glob('**/bar', g)
// sync iteration works as well
for (const file of g2) {
  console.log('found a bar file:', file)
}

// you can also pass withFileTypes: true to get Path objects
// these are like a Dirent, but with some more added powers
// check out http://npm.im/path-scurry for more info on their API
const g3 = new Glob('**/baz/**', { withFileTypes: true })
g3.stream().on('data', path => {
  console.log(
    'got a path object',
    path.fullpath(),
    path.isDirectory(),
    path.readdirSync().map(e => e.name),
  )
})

// if you use stat:true and withFileTypes, you can sort results
// by things like modified time, filter by permission mode, etc.
// All Stats fields will be available in that case. Slightly
// slower, though.
// For example:
const results = await glob('**', { stat: true, withFileTypes: true })

const timeSortedFiles = results
  .sort((a, b) => a.mtimeMs - b.mtimeMs)
  .map(path => path.fullpath())

const groupReadableFiles = results
  .filter(path => path.mode & 0o040)
  .map(path => path.fullpath())

// custom ignores can be done like this, for example by saying
// you'll ignore all markdown files, and all folders named 'docs'
const customIgnoreResults = await glob('**', {
  ignore: {
    ignored: p => /\.md$/.test(p.name),
    childrenIgnored: p => p.isNamed('docs'),
  },
})

// another fun use case, only return files with the same name as
// their parent folder, plus either `.ts` or `.js`
const folderNamedModules = await glob('**/*.{ts,js}', {
  ignore: {
    ignored: p => {
      const pp = p.parent
      return !(p.isNamed(pp.name + '.ts') || p.isNamed(pp.name + '.js'))
    },
  },
})

// find all files edited in the last hour, to do this, we ignore
// all of them that are more than an hour old
const newFiles = await glob('**', {
  // need stat so we have mtime
  stat: true,
  // only want the files, not the dirs
  nodir: true,
  ignore: {
    ignored: p => {
      return new Date() - p.mtime > 60 * 60 * 1000
    },
    // could add similar childrenIgnored here as well, but
    // directory mtime is inconsistent across platforms, so
    // probably better not to, unless you know the system
    // tracks this reliably.
  },
})
```

**Note** Glob patterns should always use `/` as a path separator,
even on Windows systems, as `\` is used to escape glob
characters. If you wish to use `\` as a path separator _instead
of_ using it as an escape character on Windows platforms, you may
set `windowsPathsNoEscape:true` in the options. In this mode,
special glob characters cannot be escaped, making it impossible
to match a literal `*` `?` and so on in filenames.

## Command Line Interface

```
$ glob -h

Usage:
  glob [options] [<pattern> [<pattern> ...]]

Expand the positional glob expression arguments into any matching file system
paths found.

  -c<command> --cmd=<command>
                         Run the command provided, passing the glob expression
                         matches as arguments.

  -A --all               By default, the glob cli command will not expand any
                         arguments that are an exact match to a file on disk.

                         This prevents double-expanding, in case the shell
                         expands an argument whose filename is a glob
                         expression.

                         For example, if 'app/*.ts' would match 'app/[id].ts',
                         then on Windows powershell or cmd.exe, 'glob app/*.ts'
                         will expand to 'app/[id].ts', as expected. However, in
                         posix shells such as bash or zsh, the shell will first
                         expand 'app/*.ts' to a list of filenames. Then glob
                         will look for a file matching 'app/[id].ts' (ie,
                         'app/i.ts' or 'app/d.ts'), which is unexpected.

                         Setting '--all' prevents this behavior, causing glob to
                         treat ALL patterns as glob expressions to be expanded,
                         even if they are an exact match to a file on disk.

                         When setting this option, be sure to enquote arguments
                         so that the shell will not expand them prior to passing
                         them to the glob command process.

  -a --absolute          Expand to absolute paths
  -d --dot-relative      Prepend './' on relative matches
  -m --mark              Append a / on any directories matched
  -x --posix             Always resolve to posix style paths, using '/' as the
                         directory separator, even on Windows. Drive letter
                         absolute matches on Windows will be expanded to their
                         full resolved UNC maths, eg instead of 'C:\foo\bar', it
                         will expand to '//?/C:/foo/bar'.

  -f --follow            Follow symlinked directories when expanding '**'
  -R --realpath          Call 'fs.realpath' on all of the results. In the case
                         of an entry that cannot be resolved, the entry is
                         omitted. This incurs a slight performance penalty, of
                         course, because of the added system calls.

  -s --stat              Call 'fs.lstat' on all entries, whether required or not
                         to determine if it's a valid match.

  -b --match-base        Perform a basename-only match if the pattern does not
                         contain any slash characters. That is, '*.js' would be
                         treated as equivalent to '**/*.js', matching js files
                         in all directories.

  --dot                  Allow patterns to match files/directories that start
                         with '.', even if the pattern does not start with '.'

  --nobrace              Do not expand {...} patterns
  --nocase               Perform a case-insensitive match. This defaults to
                         'true' on macOS and Windows platforms, and false on all
                         others.

                         Note: 'nocase' should only be explicitly set when it is
                         known that the filesystem's case sensitivity differs
                         from the platform default. If set 'true' on
                         case-insensitive file systems, then the walk may return
                         more or less results than expected.

  --nodir                Do not match directories, only files.

                         Note: to *only* match directories, append a '/' at the
                         end of the pattern.

  --noext                Do not expand extglob patterns, such as '+(a|b)'
  --noglobstar           Do not expand '**' against multiple path portions. Ie,
                         treat it as a normal '*' instead.

  --windows-path-no-escape
                         Use '\' as a path separator *only*, and *never* as an
                         escape character. If set, all '\' characters are
                         replaced with '/' in the pattern.

  -D<n> --max-depth=<n>  Maximum depth to traverse from the current working
                         directory

  -C<cwd> --cwd=<cwd>    Current working directory to execute/match in
  -r<root> --root=<root> A string path resolved against the 'cwd', which is used
                         as the starting point for absolute patterns that start
                         with '/' (but not drive letters or UNC paths on
                         Windows).

                         Note that this *doesn't* necessarily limit the walk to
                         the 'root' directory, and doesn't affect the cwd
                         starting point for non-absolute patterns. A pattern
                         containing '..' will still be able to traverse out of
                         the root directory, if it is not an actual root
                         directory on the filesystem, and any non-absolute
                         patterns will still be matched in the 'cwd'.

                         To start absolute and non-absolute patterns in the same
                         path, you can use '--root=' to set it to the empty
                         string. However, be aware that on Windows systems, a
                         pattern like 'x:/*' or '//host/share/*' will *always*
                         start in the 'x:/' or '//host/share/' directory,
                         regardless of the --root setting.

  --platform=<platform>  Defaults to the value of 'process.platform' if
                         available, or 'linux' if not. Setting --platform=win32
                         on non-Windows systems may cause strange behavior!

  -i<ignore> --ignore=<ignore>
                         Glob patterns to ignore Can be set multiple times
  -v --debug             Output a huge amount of noisy debug information about
                         patterns as they are parsed and used to match files.

  -h --help              Show this usage information
```

## `glob(pattern: string | string[], options?: GlobOptions) => Promise<string[] | Path[]>`

Perform an asynchronous glob search for the pattern(s) specified.
Returns
[Path](https://isaacs.github.io/path-scurry/classes/PathBase)
objects if the `withFileTypes` option is set to `true`. See below
for full options field desciptions.

## `globSync(pattern: string | string[], options?: GlobOptions) => string[] | Path[]`

Synchronous form of `glob()`.

Alias: `glob.sync()`

## `globIterate(pattern: string | string[], options?: GlobOptions) => AsyncGenerator<string>`

Return an async iterator for walking glob pattern matches.

Alias: `glob.iterate()`

## `globIterateSync(pattern: string | string[], options?: GlobOptions) => Generator<string>`

Return a sync iterator for walking glob pattern matches.

Alias: `glob.iterate.sync()`, `glob.sync.iterate()`

## `globStream(pattern: string | string[], options?: GlobOptions) => Minipass<string | Path>`

Return a stream that emits all the strings or `Path` objects and
then emits `end` when completed.

Alias: `glob.stream()`

## `globStreamSync(pattern: string | string[], options?: GlobOptions) => Minipass<string | Path>`

Syncronous form of `globStream()`. Will read all the matches as
fast as you consume them, even all in a single tick if you
consume them immediately, but will still respond to backpressure
if they're not consumed immediately.

Alias: `glob.stream.sync()`, `glob.sync.stream()`

## `hasMagic(pattern: string | string[], options?: GlobOptions) => boolean`

Returns `true` if the provided pattern contains any "magic" glob
characters, given the options provided.

Brace expansion is not considered "magic" unless the
`magicalBraces` option is set, as brace expansion just turns one
string into an array of strings. So a pattern like `'x{a,b}y'`
would return `false`, because `'xay'` and `'xby'` both do not
contain any magic glob characters, and it's treated the same as
if you had called it on `['xay', 'xby']`. When
`magicalBraces:true` is in the options, brace expansion _is_
treated as a pattern having magic.

## `escape(pattern: string, options?: GlobOptions) => string`

Escape all magic characters in a glob pattern, so that it will
only ever match literal strings

If the `windowsPathsNoEscape` option is used, then characters are
escaped by wrapping in `[]`, because a magic character wrapped in
a character class can only be satisfied by that exact character.

Slashes (and backslashes in `windowsPathsNoEscape` mode) cannot
be escaped or unescaped.

## `unescape(pattern: string, options?: GlobOptions) => string`

Un-escape a glob string that may contain some escaped characters.

If the `windowsPathsNoEscape` option is used, then square-brace
escapes are removed, but not backslash escapes. For example, it
will turn the string `'[*]'` into `*`, but it will not turn
`'\\*'` into `'*'`, because `\` is a path separator in
`windowsPathsNoEscape` mode.

When `windowsPathsNoEscape` is not set, then both brace escapes
and backslash escapes are removed.

Slashes (and backslashes in `windowsPathsNoEscape` mode) cannot
be escaped or unescaped.

## Class `Glob`

An object that can perform glob pattern traversals.

### `const g = new Glob(pattern: string | string[], options: GlobOptions)`

Options object is required.

See full options descriptions below.

Note that a previous `Glob` object can be passed as the
`GlobOptions` to another `Glob` instantiation to re-use settings
and caches with a new pattern.

Traversal functions can be called multiple times to run the walk
again.

### `g.stream()`

Stream results asynchronously,

### `g.streamSync()`

Stream results synchronously.

### `g.iterate()`

Default async iteration function. Returns an AsyncGenerator that
iterates over the results.

### `g.iterateSync()`

Default sync iteration function. Returns a Generator that
iterates over the results.

### `g.walk()`

Returns a Promise that resolves to the results array.

### `g.walkSync()`

Returns a results array.

### Properties

All options are stored as properties on the `Glob` object.

- `opts` The options provided to the constructor.
- `patterns` An array of parsed immutable `Pattern` objects.

## Options

Exported as `GlobOptions` TypeScript interface. A `GlobOptions`
object may be provided to any of the exported methods, and must
be provided to the `Glob` constructor.

All options are optional, boolean, and false by default, unless
otherwise noted.

All resolved options are added to the Glob object as properties.

If you are running many `glob` operations, you can pass a Glob
object as the `options` argument to a subsequent operation to
share the previously loaded cache.

- `cwd` String path or `file://` string or URL object. The
  current working directory in which to search. Defaults to
  `process.cwd()`. See also: "Windows, CWDs, Drive Letters, and
  UNC Paths", below.

  This option may be either a string path or a `file://` URL
  object or string.

- `root` A string path resolved against the `cwd` option, which
  is used as the starting point for absolute patterns that start
  with `/`, (but not drive letters or UNC paths on Windows).

  Note that this _doesn't_ necessarily limit the walk to the
  `root` directory, and doesn't affect the cwd starting point for
  non-absolute patterns. A pattern containing `..` will still be
  able to traverse out of the root directory, if it is not an
  actual root directory on the filesystem, and any non-absolute
  patterns will be matched in the `cwd`. For example, the
  pattern `/../*` with `{root:'/some/path'}` will return all
  files in `/some`, not all files in `/some/path`. The pattern
  `*` with `{root:'/some/path'}` will return all the entries in
  the cwd, not the entries in `/some/path`.

  To start absolute and non-absolute patterns in the same
  path, you can use `{root:''}`. However, be aware that on
  Windows systems, a pattern like `x:/*` or `//host/share/*` will
  _always_ start in the `x:/` or `//host/share` directory,
  regardless of the `root` setting.

- `windowsPathsNoEscape` Use `\\` as a path separator _only_, and
  _never_ as an escape character. If set, all `\\` characters are
  replaced with `/` in the pattern.

  Note that this makes it **impossible** to match against paths
  containing literal glob pattern characters, but allows matching
  with patterns constructed using `path.join()` and
  `path.resolve()` on Windows platforms, mimicking the (buggy!)
  behavior of Glob v7 and before on Windows. Please use with
  caution, and be mindful of [the caveat below about Windows
  paths](#windows). (For legacy reasons, this is also set if
  `allowWindowsEscape` is set to the exact value `false`.)

- `dot` Include `.dot` files in normal matches and `globstar`
  matches. Note that an explicit dot in a portion of the pattern
  will always match dot files.

- `magicalBraces` Treat brace expansion like `{a,b}` as a "magic"
  pattern. Has no effect if {@link nobrace} is set.

  Only has effect on the {@link hasMagic} function, no effect on
  glob pattern matching itself.

- `dotRelative` Prepend all relative path strings with `./` (or
  `.\` on Windows).

  Without this option, returned relative paths are "bare", so
  instead of returning `'./foo/bar'`, they are returned as
  `'foo/bar'`.

  Relative patterns starting with `'../'` are not prepended with
  `./`, even if this option is set.

- `mark` Add a `/` character to directory matches. Note that this
  requires additional stat calls.

- `nobrace` Do not expand `{a,b}` and `{1..3}` brace sets.

- `noglobstar` Do not match `**` against multiple filenames. (Ie,
  treat it as a normal `*` instead.)

- `noext` Do not match "extglob" patterns such as `+(a|b)`.

- `nocase` Perform a case-insensitive match. This defaults to
  `true` on macOS and Windows systems, and `false` on all others.

  **Note** `nocase` should only be explicitly set when it is
  known that the filesystem's case sensitivity differs from the
  platform default. If set `true` on case-sensitive file
  systems, or `false` on case-insensitive file systems, then the
  walk may return more or less results than expected.

- `maxDepth` Specify a number to limit the depth of the directory
  traversal to this many levels below the `cwd`.

- `matchBase` Perform a basename-only match if the pattern does
  not contain any slash characters. That is, `*.js` would be
  treated as equivalent to `**/*.js`, matching all js files in
  all directories.

- `nodir` Do not match directories, only files. (Note: to match
  _only_ directories, put a `/` at the end of the pattern.)

  Note: when `follow` and `nodir` are both set, then symbolic
  links to directories are also omitted.

- `stat` Call `lstat()` on all entries, whether required or not
  to determine whether it's a valid match. When used with
  `withFileTypes`, this means that matches will include data such
  as modified time, permissions, and so on. Note that this will
  incur a performance cost due to the added system calls.

- `ignore` string or string[], or an object with `ignore` and
  `ignoreChildren` methods.

  If a string or string[] is provided, then this is treated as a
  glob pattern or array of glob patterns to exclude from matches.
  To ignore all children within a directory, as well as the entry
  itself, append `'/**'` to the ignore pattern.

  **Note** `ignore` patterns are _always_ in `dot:true` mode,
  regardless of any other settings.

  If an object is provided that has `ignored(path)` and/or
  `childrenIgnored(path)` methods, then these methods will be
  called to determine whether any Path is a match or if its
  children should be traversed, respectively.

- `follow` Follow symlinked directories when expanding `**`
  patterns. This can result in a lot of duplicate references in
  the presence of cyclic links, and make performance quite bad.

  By default, a `**` in a pattern will follow 1 symbolic link if
  it is not the first item in the pattern, or none if it is the
  first item in the pattern, following the same behavior as Bash.

  Note: when `follow` and `nodir` are both set, then symbolic
  links to directories are also omitted.

- `realpath` Set to true to call `fs.realpath` on all of the
  results. In the case of an entry that cannot be resolved, the
  entry is omitted. This incurs a slight performance penalty, of
  course, because of the added system calls.

- `absolute` Set to true to always receive absolute paths for
  matched files. Set to `false` to always receive relative paths
  for matched files.

  By default, when this option is not set, absolute paths are
  returned for patterns that are absolute, and otherwise paths
  are returned that are relative to the `cwd` setting.

  This does _not_ make an extra system call to get the realpath,
  it only does string path resolution.

  `absolute` may not be used along with `withFileTypes`.

- `posix` Set to true to use `/` as the path separator in
  returned results. On posix systems, this has no effect. On
  Windows systems, this will return `/` delimited path results,
  and absolute paths will be returned in their full resolved UNC
  path form, eg insted of `'C:\\foo\\bar'`, it will return
  `//?/C:/foo/bar`.

- `platform` Defaults to value of `process.platform` if
  available, or `'linux'` if not. Setting `platform:'win32'` on
  non-Windows systems may cause strange behavior.

- `withFileTypes` Return [PathScurry](http://npm.im/path-scurry)
  `Path` objects instead of strings. These are similar to a
  NodeJS `Dirent` object, but with additional methods and
  properties.

  `withFileTypes` may not be used along with `absolute`.

- `signal` An AbortSignal which will cancel the Glob walk when
  triggered.

- `fs` An override object to pass in custom filesystem methods.
  See [PathScurry docs](http://npm.im/path-scurry) for what can
  be overridden.

- `scurry` A [PathScurry](http://npm.im/path-scurry) object used
  to traverse the file system. If the `nocase` option is set
  explicitly, then any provided `scurry` object must match this
  setting.

- `includeChildMatches` boolean, default `true`. Do not match any
  children of any matches. For example, the pattern `**\/foo`
  would match `a/foo`, but not `a/foo/b/foo` in this mode.

  This is especially useful for cases like "find all
  `node_modules` folders, but not the ones in `node_modules`".

  In order to support this, the `Ignore` implementation must
  support an `add(pattern: string)` method. If using the default
  `Ignore` class, then this is fine, but if this is set to
  `false`, and a custom `Ignore` is provided that does not have
  an `add()` method, then it will throw an error.

  **Caveat** It _only_ ignores matches that would be a descendant
  of a previous match, and only if that descendant is matched
  _after_ the ancestor is encountered. Since the file system walk
  happens in indeterminate order, it's possible that a match will
  already be added before its ancestor, if multiple or braced
  patterns are used.

  For example:

  ```js
  const results = await glob(
    [
      // likely to match first, since it's just a stat
      'a/b/c/d/e/f',

      // this pattern is more complicated! It must to various readdir()
      // calls and test the results against a regular expression, and that
      // is certainly going to take a little bit longer.
      //
      // So, later on, it encounters a match at 'a/b/c/d/e', but it's too
      // late to ignore a/b/c/d/e/f, because it's already been emitted.
      'a/[bdf]/?/[a-z]/*',
    ],
    { includeChildMatches: false },
  )
  ```

  It's best to only set this to `false` if you can be reasonably
  sure that no components of the pattern will potentially match
  one another's file system descendants, or if the occasional
  included child entry will not cause problems.

## Glob Primer

Much more information about glob pattern expansion can be found
by running `man bash` and searching for `Pattern Matching`.

"Globs" are the patterns you type when you do stuff like `ls
*.js` on the command line, or put `build/*` in a `.gitignore`
file.

Before parsing the path part patterns, braced sections are
expanded into a set. Braced sections start with `{` and end with
`}`, with 2 or more comma-delimited sections within. Braced
sections may contain slash characters, so `a{/b/c,bcd}` would
expand into `a/b/c` and `abcd`.

The following characters have special magic meaning when used in
a path portion. With the exception of `**`, none of these match
path separators (ie, `/` on all platforms, and `\` on Windows).

- `*` Matches 0 or more characters in a single path portion.
  When alone in a path portion, it must match at least 1
  character. If `dot:true` is not specified, then `*` will not
  match against a `.` character at the start of a path portion.
- `?` Matches 1 character. If `dot:true` is not specified, then
  `?` will not match against a `.` character at the start of a
  path portion.
- `[...]` Matches a range of characters, similar to a RegExp
  range. If the first character of the range is `!` or `^` then
  it matches any character not in the range. If the first
  character is `]`, then it will be considered the same as `\]`,
  rather than the end of the character class.
- `!(pattern|pattern|pattern)` Matches anything that does not
  match any of the patterns provided. May _not_ contain `/`
  characters. Similar to `*`, if alone in a path portion, then
  the path portion must have at least one character.
- `?(pattern|pattern|pattern)` Matches zero or one occurrence of
  the patterns provided. May _not_ contain `/` characters.
- `+(pattern|pattern|pattern)` Matches one or more occurrences of
  the patterns provided. May _not_ contain `/` characters.
- `*(a|b|c)` Matches zero or more occurrences of the patterns
  provided. May _not_ contain `/` characters.
- `@(pattern|pat*|pat?erN)` Matches exactly one of the patterns
  provided. May _not_ contain `/` characters.
- `**` If a "globstar" is alone in a path portion, then it
  matches zero or more directories and subdirectories searching
  for matches. It does not crawl symlinked directories, unless
  `{follow:true}` is passed in the options object. A pattern
  like `a/b/**` will only match `a/b` if it is a directory.
  Follows 1 symbolic link if not the first item in the pattern,
  or 0 if it is the first item, unless `follow:true` is set, in
  which case it follows all symbolic links.

`[:class:]` patterns are supported by this implementation, but
`[=c=]` and `[.symbol.]` style class patterns are not.

### Dots

If a file or directory path portion has a `.` as the first
character, then it will not match any glob pattern unless that
pattern's corresponding path part also has a `.` as its first
character.

For example, the pattern `a/.*/c` would match the file at
`a/.b/c`. However the pattern `a/*/c` would not, because `*` does
not start with a dot character.

You can make glob treat dots as normal characters by setting
`dot:true` in the options.

### Basename Matching

If you set `matchBase:true` in the options, and the pattern has
no slashes in it, then it will seek for any file anywhere in the
tree with a matching basename. For example, `*.js` would match
`test/simple/basic.js`.

### Empty Sets

If no matching files are found, then an empty array is returned.
This differs from the shell, where the pattern itself is
returned. For example:

```sh
$ echo a*s*d*f
a*s*d*f
```

## Comparisons to other fnmatch/glob implementations

While strict compliance with the existing standards is a
worthwhile goal, some discrepancies exist between node-glob and
other implementations, and are intentional.

The double-star character `**` is supported by default, unless
the `noglobstar` flag is set. This is supported in the manner of
bsdglob and bash 5, where `**` only has special significance if
it is the only thing in a path part. That is, `a/**/b` will match
`a/x/y/b`, but `a/**b` will not.

Note that symlinked directories are not traversed as part of a
`**`, though their contents may match against subsequent portions
of the pattern. This prevents infinite loops and duplicates and
the like. You can force glob to traverse symlinks with `**` by
setting `{follow:true}` in the options.

There is no equivalent of the `nonull` option. A pattern that
does not find any matches simply resolves to nothing. (An empty
array, immediately ended stream, etc.)

If brace expansion is not disabled, then it is performed before
any other interpretation of the glob pattern. Thus, a pattern
like `+(a|{b),c)}`, which would not be valid in bash or zsh, is
expanded **first** into the set of `+(a|b)` and `+(a|c)`, and
those patterns are checked for validity. Since those two are
valid, matching proceeds.

The character class patterns `[:class:]` (posix standard named
classes) style class patterns are supported and unicode-aware,
but `[=c=]` (locale-specific character collation weight), and
`[.symbol.]` (collating symbol), are not.

### Repeated Slashes

Unlike Bash and zsh, repeated `/` are always coalesced into a
single path separator.

### Comments and Negation

Previously, this module let you mark a pattern as a "comment" if
it started with a `#` character, or a "negated" pattern if it
started with a `!` character.

These options were deprecated in version 5, and removed in
version 6.

To specify things that should not match, use the `ignore` option.

## Windows

**Please only use forward-slashes in glob expressions.**

Though windows uses either `/` or `\` as its path separator, only
`/` characters are used by this glob implementation. You must use
forward-slashes **only** in glob expressions. Back-slashes will
always be interpreted as escape characters, not path separators.

Results from absolute patterns such as `/foo/*` are mounted onto
the root setting using `path.join`. On windows, this will by
default result in `/foo/*` matching `C:\foo\bar.txt`.

To automatically coerce all `\` characters to `/` in pattern
strings, **thus making it impossible to escape literal glob
characters**, you may set the `windowsPathsNoEscape` option to
`true`.

### Windows, CWDs, Drive Letters, and UNC Paths

On posix systems, when a pattern starts with `/`, any `cwd`
option is ignored, and the traversal starts at `/`, plus any
non-magic path portions specified in the pattern.

On Windows systems, the behavior is similar, but the concept of
an "absolute path" is somewhat more involved.

#### UNC Paths

A UNC path may be used as the start of a pattern on Windows
platforms. For example, a pattern like: `//?/x:/*` will return
all file entries in the root of the `x:` drive. A pattern like
`//ComputerName/Share/*` will return all files in the associated
share.

UNC path roots are always compared case insensitively.

#### Drive Letters

A pattern starting with a drive letter, like `c:/*`, will search
in that drive, regardless of any `cwd` option provided.

If the pattern starts with `/`, and is not a UNC path, and there
is an explicit `cwd` option set with a drive letter, then the
drive letter in the `cwd` is used as the root of the directory
traversal.

For example, `glob('/tmp', { cwd: 'c:/any/thing' })` will return
`['c:/tmp']` as the result.

If an explicit `cwd` option is not provided, and the pattern
starts with `/`, then the traversal will run on the root of the
drive provided as the `cwd` option. (That is, it is the result of
`path.resolve('/')`.)

## Race Conditions

Glob searching, by its very nature, is susceptible to race
conditions, since it relies on directory walking.

As a result, it is possible that a file that exists when glob
looks for it may have been deleted or modified by the time it
returns the result.

By design, this implementation caches all readdir calls that it
makes, in order to cut down on system overhead. However, this
also makes it even more susceptible to races, especially if the
cache object is reused between glob calls.

Users are thus advised not to use a glob result as a guarantee of
filesystem state in the face of rapid changes. For the vast
majority of operations, this is never a problem.

## Comparison to Other JavaScript Glob Implementations

**tl;dr**

- If you want glob matching that is as faithful as possible to
  Bash pattern expansion semantics, and as fast as possible
  within that constraint, _use this module_.
- If you are reasonably sure that the patterns you will encounter
  are relatively simple, and want the absolutely fastest glob
  matcher out there, _use [fast-glob](http://npm.im/fast-glob)_.
- If you are reasonably sure that the patterns you will encounter
  are relatively simple, and want the convenience of
  automatically respecting `.gitignore` files, _use
  [globby](http://npm.im/globby)_.

There are some other glob matcher libraries on npm, but these
three are (in my opinion, as of 2023) the best.

---

**full explanation**

Every library reflects a set of opinions and priorities in the
trade-offs it makes. Other than this library, I can personally
recommend both [globby](http://npm.im/globby) and
[fast-glob](http://npm.im/fast-glob), though they differ in their
benefits and drawbacks.

Both have very nice APIs and are reasonably fast.

`fast-glob` is, as far as I am aware, the fastest glob
implementation in JavaScript today. However, there are many
cases where the choices that `fast-glob` makes in pursuit of
speed mean that its results differ from the results returned by
Bash and other sh-like shells, which may be surprising.

In my testing, `fast-glob` is around 10-20% faster than this
module when walking over 200k files nested 4 directories
deep[1](#fn-webscale). However, there are some inconsistencies
with Bash matching behavior that this module does not suffer
from:

- `**` only matches files, not directories
- `..` path portions are not handled unless they appear at the
  start of the pattern
- `./!(<pattern>)` will not match any files that _start_ with
  `<pattern>`, even if they do not match `<pattern>`. For
  example, `!(9).txt` will not match `9999.txt`.
- Some brace patterns in the middle of a pattern will result in
  failing to find certain matches.
- Extglob patterns are allowed to contain `/` characters.

Globby exhibits all of the same pattern semantics as fast-glob,
(as it is a wrapper around fast-glob) and is slightly slower than
node-glob (by about 10-20% in the benchmark test set, or in other
words, anywhere from 20-50% slower than fast-glob). However, it
adds some API conveniences that may be worth the costs.

- Support for `.gitignore` and other ignore files.
- Support for negated globs (ie, patterns starting with `!`
  rather than using a separate `ignore` option).

The priority of this module is "correctness" in the sense of
performing a glob pattern expansion as faithfully as possible to
the behavior of Bash and other sh-like shells, with as much speed
as possible.

Note that prior versions of `node-glob` are _not_ on this list.
Former versions of this module are far too slow for any cases
where performance matters at all, and were designed with APIs
that are extremely dated by current JavaScript standards.

returns results and `fast-glob` doesn't, it's even faster, of
course.</small>

     *   // So, later on, it encounters a match at 'a/b/c/d/e', but it's too
     *   // late to ignore a/b/c/d/e/f, because it's already been emitted.

                    This prevents double-expanding, in case the shell expands
                    an argument whose filename is a glob expression.

                    For example, if 'app/*.ts' would match 'app/[id].ts', then
                    on Windows powershell or cmd.exe, 'glob app/*.ts' will
                    expand to 'app/[id].ts', as expected. However, in posix
                    shells such as bash or zsh, the shell will first expand
                    'app/*.ts' to a list of filenames. Then glob will look
                    for a file matching 'app/[id].ts' (ie, 'app/i.ts' or
                    'app/d.ts'), which is unexpected.

                    Setting '--all' prevents this behavior, causing glob
                    to treat ALL patterns as glob expressions to be expanded,
                    even if they are an exact match to a file on disk.

                    When setting this option, be sure to enquote arguments
                    so that the shell will not expand them prior to passing
                    them to the glob command process.

    // == Japanese/ShiftJIS ====================================================
    // All japanese encodings are based on JIS X set of standards:
    // JIS X 0201 - Single-byte encoding of ASCII + ¥ + Kana chars at 0xA1-0xDF.
    // JIS X 0208 - Main set of 6879 characters, placed in 94x94 plane, to be encoded by 2 bytes. 
    //              Has several variations in 1978, 1983, 1990 and 1997.
    // JIS X 0212 - Supplementary plane of 6067 chars in 94x94 plane. 1990. Effectively dead.
    // JIS X 0213 - Extension and modern replacement of 0208 and 0212. Total chars: 11233.
    //              2 planes, first is superset of 0208, second - revised 0212.
    //              Introduced in 2000, revised 2004. Some characters are in Unicode Plane 2 (0x2xxxx)

    // Byte encodings are:
    //  * Shift_JIS: Compatible with 0201, uses not defined chars in top half as lead bytes for double-byte
    //               encoding of 0208. Lead byte ranges: 0x81-0x9F, 0xE0-0xEF; Trail byte ranges: 0x40-0x7E, 0x80-0x9E, 0x9F-0xFC.
    //               Windows CP932 is a superset of Shift_JIS. Some companies added more chars, notably KDDI.
    //  * EUC-JP:    Up to 3 bytes per character. Used mostly on *nixes.
    //               0x00-0x7F       - lower part of 0201
    //               0x8E, 0xA1-0xDF - upper part of 0201
    //               (0xA1-0xFE)x2   - 0208 plane (94x94).
    //               0x8F, (0xA1-0xFE)x2 - 0212 plane (94x94).
    //  * JIS X 208: 7-bit, direct encoding of 0208. Byte ranges: 0x21-0x7E (94 values). Uncommon.
    //               Used as-is in ISO2022 family.
    //  * ISO2022-JP: Stateful encoding, with escape sequences to switch between ASCII, 
    //                0201-1976 Roman, 0208-1978, 0208-1983.
    //  * ISO2022-JP-1: Adds esc seq for 0212-1990.
    //  * ISO2022-JP-2: Adds esc seq for GB2313-1980, KSX1001-1992, ISO8859-1, ISO8859-7.
    //  * ISO2022-JP-3: Adds esc seq for 0201-1976 Kana set, 0213-2000 Planes 1, 2.
    //  * ISO2022-JP-2004: Adds 0213-2004 Plane 1.
    //
    // After JIS X 0213 appeared, Shift_JIS-2004, EUC-JISX0213 and ISO2022-JP-2004 followed, with just changing the planes.

# libnpmaccess

[![npm version](https://img.shields.io/npm/v/libnpmaccess.svg)](https://npm.im/libnpmaccess)
[![license](https://img.shields.io/npm/l/libnpmaccess.svg)](https://npm.im/libnpmaccess)
[![CI - libnpmaccess](https://github.com/npm/cli/actions/workflows/ci-libnpmaccess.yml/badge.svg)](https://github.com/npm/cli/actions/workflows/ci-libnpmaccess.yml)

[`libnpmaccess`](https://github.com/npm/libnpmaccess) is a Node.js
library that provides programmatic access to the guts of the npm CLI's `npm
access` command. This includes managing account mfa settings, listing
packages and permissions, looking at package collaborators, and defining
package permissions for users, orgs, and teams.

## Example

```javascript
const access = require('libnpmaccess')
const opts = { '//registry.npmjs.org/:_authToken: 'npm_token }

// List all packages @zkat has access to on the npm registry.
console.log(Object.keys(await access.getPackages('zkat', opts)))
```

### API

#### `opts` for all `libnpmaccess` commands

`libnpmaccess` uses [`npm-registry-fetch`](https://npm.im/npm-registry-fetch).

All options are passed through directly to that library, so please refer
to [its own `opts`
documentation](https://www.npmjs.com/package/npm-registry-fetch#fetch-options)
for options that can be passed in.

#### `spec` parameter for all `libnpmaccess` commands

`spec` must be an [`npm-package-arg`](https://npm.im/npm-package-arg)-compatible
registry spec.

#### `access.getCollaborators(spec, opts) -> Promise<Object>`

Gets collaborators for a given package

#### `access.getPackages(user|scope|team, opts) -> Promise<Object>`

Gets all packages for a given user, scope, or team.

Teams should be in the format `scope:team` or `@scope:team`

Users and scopes can be in the format `@scope` or `scope`

#### `access.getVisibility(spec, opts) -> Promise<Object>`

Gets the visibility of a given package

#### `access.removePermissions(team, spec, opts) -> Promise<Boolean>`

Removes the access for a given team to a package.

Teams should be in the format `scope:team` or `@scope:team`

#### `access.setAccess(package, access, opts) -> Promise<Boolean>`

Sets access level for package described by `spec`.

The npm registry accepts the following `access` levels:

`public`: package is public
`private`: package is private

The npm registry also only allows scoped packages to have their access
level set.

#### access.setMfa(spec, level, opts) -> Promise<Boolean>`

Sets the publishing mfa requirements for a given package.  Level must be one of the
following

`none`: mfa is not required to publish this package.
`publish`: mfa is required to publish this package, automation tokens
cannot be used to publish.
`automation`: mfa is required to publish this package, automation tokens
may also be used for publishing from continuous integration workflows.

#### access.setPermissions(team, spec, permssions, opts) -> Promise<Boolean>`

Sets permissions levels for a given team to a package.

Teams should be in the format `scope:team` or `@scope:team`

The npm registry accepts the following `permissions`:

`read-only`: Read only permissions
`read-write`: Read and write (aka publish) permissions

### API

#### `> libnpmdif([ a, b ], [opts]) -> Promise<String>`

Fetches the registry tarballs and compare files between a spec `a` and spec `b`. **npm** spec types are usually described in `<pkg-name>@<version>` form but multiple other types are alsos supported, for more info on valid specs take a look at [`npm-package-arg`](https://github.com/npm/npm-package-arg).

**Options**:

- `color <Boolean>`: Should add ANSI colors to string output? Defaults to `false`.
- `tagVersionPrefix <Sring>`: What prefix should be used to define version numbers. Defaults to `v`
- `diffUnified <Number>`: How many lines of code to print before/after each diff. Defaults to `3`.
- `diffFiles <Array<String>>`: If set only prints patches for the files listed in this array (also accepts globs). Defaults to `undefined`.
- `diffIgnoreAllSpace <Boolean>`: Whether or not should ignore changes in whitespace (very useful to avoid indentation changes extra diff lines). Defaults to `false`.
- `diffNameOnly <Boolean>`: Prints only file names and no patch diffs. Defaults to `false`.
- `diffNoPrefix <Boolean>`: If true then skips printing any prefixes in filenames. Defaults to `false`.
- `diffSrcPrefix <String>`: Prefix to be used in the filenames from `a`. Defaults to `a/`.
- `diffDstPrefix <String>`: Prefix to be used in the filenames from `b`. Defaults to `b/`.
- `diffText <Boolean>`: Should treat all files as text and try to print diff for binary files. Defaults to `false`.
- ...`cache`, `registry`, `where` and other common options accepted by [pacote](https://github.com/npm/pacote#options)

Returns a `Promise` that fullfils with a `String` containing the resulting patch diffs.

Throws an error if either `a` or `b` are missing or if trying to diff more than two specs.

[![CI - libnpmexec](https://github.com/npm/cli/actions/workflows/ci-libnpmexec.yml/badge.svg)](https://github.com/npm/cli/actions/workflows/ci-libnpmexec.yml)

The `npm exec` (`npx`) Programmatic API

## Install

`npm install libnpmexec`

## Usage:

```js
const libexec = require('libnpmexec')
await libexec({
  args: ['yosay', 'Bom dia!'],
  cache: '~/.npm/_cacache',
  npxCache: '~/.npm/_npx',
  yes: true,
})
```

## API:

### `libexec(opts)`

- `opts`:
  - `args`: List of pkgs to execute **Array<String>**, defaults to `[]`
  - `call`: An alternative command to run when using `packages` option **String**, defaults to empty string.
  - `cache`: The path location to where the npm cache folder is placed **String**
  - `npxCache`: The path location to where the npx cache folder is placed **String**
  - `chalk`: Chalk instance to use for colors? **Required**
  - `localBin`: Location to the `node_modules/.bin` folder of the local project to start scanning for bin files **String**, defaults to `./node_modules/.bin`. **libexec** will walk up the directory structure looking for `node_modules/.bin` folders in parent folders that might satisfy the current `arg` and will use that bin if found.
  - `locationMsg`: Overrides "at location" message when entering interactive mode **String**
  - `globalBin`: Location to the global space bin folder, same as: `$(npm bin -g)` **String**, defaults to empty string.
  - `packages`: A list of packages to be used (possibly fetch from the registry) **Array<String>**, defaults to `[]`
  - `path`: Location to where to read local project info (`package.json`) **String**, defaults to `.`
  - `runPath`: Location to where to execute the script **String**, defaults to `.`
  - `scriptShell`: Default shell to be used **String**, defaults to `sh` on POSIX systems, `process.env.ComSpec` OR `cmd` on Windows
  - `yes`: Should skip download confirmation prompt when fetching missing packages from the registry? **Boolean**
  - `registry`, `cache`, and more options that are forwarded to [@npmcli/arborist](https://github.com/npm/arborist/) and [pacote](https://github.com/npm/pacote/#options) **Object**

### API

##### <a name="fund.read"></a> `> fund.read([opts]) -> Promise<Object>`

Reads **funding** info from a npm install and returns a promise for a
tree object that only contains packages in which funding info is defined.

Options:

- `countOnly`: Uses the tree-traversal logic from **npm fund** but skips over
any obj definition and just returns an obj containing `{ length }` - useful for
things such as printing a `6 packages are looking for funding` msg.
- `workspaces`: `Array<String>` List of workspaces names to filter for,
the result will only include a subset of the resulting tree that includes
only the nodes that are children of the listed workspaces names.
- `path`, `registry` and more [Arborist](https://github.com/npm/arborist/) options.

##### <a name="fund.readTree"></a> `> fund.readTree(tree, [opts]) -> Promise<Object>`

Reads **funding** info from a given install tree and returns a tree object
that only contains packages in which funding info is defined.

- `tree`: An [`arborist`](https://github.com/npm/arborist) tree to be used, e.g:

```js
const Arborist = require('@npmcli/arborist')
const { readTree } = require('libnpmfund')

const arb = new Arborist({ path: process.cwd() })
const tree = await arb.loadActual()

return readTree(tree, { countOnly: false })
```

Options:

- `countOnly`: Uses the tree-traversal logic from **npm fund** but skips over
any obj definition and just returns an obj containing `{ length }` - useful for
things such as printing a `6 packages are looking for funding` msg.

##### <a name="fund.normalizeFunding"></a> `> fund.normalizeFunding(funding) -> Object`

From a `funding` `<object|string|array>`, retrieves normalized funding objects
containing a `url` property.

e.g:

```js
normalizeFunding('http://example.com')
// => {
  url: 'http://example.com'
}
```

##### <a name="fund.isValidFunding"></a> `> fund.isValidFunding(funding) -> Boolean`

Returns `<true>` if `funding` is a valid funding object, e.g:

```js
isValidFunding({ foo: 'not a valid funding obj' })
// => false

isValidFunding('http://example.com')
// => true
```

[`libnpmorg`](https://github.com/npm/libnpmorg) is a Node.js library for
programmatically accessing the [npm Org membership
API](https://github.com/npm/registry/blob/master/docs/orgs/memberships.md#membership-detail).

## Table of Contents

* [Example](#example)
* [Install](#install)
* [Contributing](#contributing)
* [API](#api)
  * [hook opts](#opts)
  * [`set()`](#set)
  * [`rm()`](#rm)
  * [`ls()`](#ls)
  * [`ls.stream()`](#ls-stream)

## Example

```js
const org = require('libnpmorg')

console.log(await org.ls('myorg', {token: 'deadbeef'}))
=>
Roster {
  zkat: 'developer',
  iarna: 'admin',
  isaacs: 'owner'
}
```

## Install

`$ npm install libnpmorg`

### API

#### <a name="opts"></a> `opts` for `libnpmorg` commands

`libnpmorg` uses [`npm-registry-fetch`](https://npm.im/npm-registry-fetch).
All options are passed through directly to that library, so please refer to [its
own `opts`
documentation](https://www.npmjs.com/package/npm-registry-fetch#fetch-options)
for options that can be passed in.

A couple of options of note for those in a hurry:

* `opts.token` - can be passed in and will be used as the authentication token for the registry. For other ways to pass in auth details, see the n-r-f docs.
* `opts.otp` - certain operations will require an OTP token to be passed in. If a `libnpmorg` command fails with `err.code === EOTP`, please retry the request with `{otp: <2fa token>}`

#### <a name="set"></a> `> org.set(org, user, [role], [opts]) -> Promise`

The returned Promise resolves to a [Membership
Detail](https://github.com/npm/registry/blob/master/docs/orgs/memberships.md#membership-detail)
object.

The `role` is optional and should be one of `admin`, `owner`, or `developer`.
`developer` is the default if no `role` is provided.

`org` and `user` must be scope names for the org name and user name
respectively. They can optionally be prefixed with `@`.

See also: [`PUT
/-/org/:scope/user`](https://github.com/npm/registry/blob/master/docs/orgs/memberships.md#org-membership-replace)

##### Example

```javascript
await org.set('@myorg', '@myuser', 'admin', {token: 'deadbeef'})
=>
MembershipDetail {
  org: {
    name: 'myorg',
    size: 15
  },
  user: 'myuser',
  role: 'admin'
}
```

#### <a name="rm"></a> `> org.rm(org, user, [opts]) -> Promise`

The Promise resolves to `null` on success.

`org` and `user` must be scope names for the org name and user name
respectively. They can optionally be prefixed with `@`.

See also: [`DELETE
/-/org/:scope/user`](https://github.com/npm/registry/blob/master/docs/orgs/memberships.md#org-membership-delete)

##### Example

```javascript
await org.rm('myorg', 'myuser', {token: 'deadbeef'})
```

#### <a name="ls"></a> `> org.ls(org, [opts]) -> Promise`

The Promise resolves to a
[Roster](https://github.com/npm/registry/blob/master/docs/orgs/memberships.md#roster)
object.

`org` must be a scope name for an org, and can be optionally prefixed with `@`.

See also: [`GET
/-/org/:scope/user`](https://github.com/npm/registry/blob/master/docs/orgs/memberships.md#org-roster)

##### Example

```javascript
await org.ls('myorg', {token: 'deadbeef'})
=>
Roster {
  zkat: 'developer',
  iarna: 'admin',
  isaacs: 'owner'
}
```

#### <a name="ls-stream"></a> `> org.ls.stream(org, [opts]) -> Stream`

Returns a stream of entries for a
[Roster](https://github.com/npm/registry/blob/master/docs/orgs/memberships.md#roster),
with each emitted entry in `[key, value]` format.

`org` must be a scope name for an org, and can be optionally prefixed with `@`.

The returned stream is a valid `Symbol.asyncIterator`.

See also: [`GET
/-/org/:scope/user`](https://github.com/npm/registry/blob/master/docs/orgs/memberships.md#org-roster)

##### Example

[`libnpmpack`](https://github.com/npm/libnpmpack) is a Node.js library for
programmatically packing tarballs from a local directory or from a registry or github spec. If packing from a local source, `libnpmpack` will also run the `prepack` and `postpack` lifecycles.

## Table of Contents

* [Example](#example)
* [Install](#install)
* [API](#api)
  * [`pack()`](#pack)

## Example

```js
const pack = require('libnpmpack')
```

## Install

`$ npm install libnpmpack`

### API

#### <a name="pack"></a> `> pack(spec, [opts]) -> Promise`

Packs a tarball from a local directory or from a registry or github spec and returns a Promise that resolves to the tarball data Buffer, with from, resolved, and integrity fields attached.

If no options are passed, the tarball file will be saved on the same directory from which `pack` was called in.
 
`libnpmpack` uses [`pacote`](https://npm.im/pacote).
Most options are passed through directly to that library, so please refer to
[its own `opts`
documentation](https://www.npmjs.com/package/pacote#options)
for options that can be passed in.

##### Examples

```javascript
// packs from cwd
const tarball = await pack()

// packs from a local directory
const localTar = await pack('/Users/claudiahdz/projects/my-cool-pkg')

// packs from a registry spec
const registryTar = await pack('abbrev@1.0.3')

// packs from a github spec
const githubTar = await pack('isaacs/rimraf#PR-192')
```
'use strict'

const pacote = require('pacote')
const npa = require('npm-package-arg')
const runScript = require('@npmcli/run-script')
const path = require('node:path')
const Arborist = require('@npmcli/arborist')
const { writeFile } = require('node:fs/promises')

module.exports = pack
async function pack (spec = 'file:.', opts = {}) {
  // gets spec
  spec = npa(spec)

  const manifest = await pacote.manifest(spec, { ...opts, Arborist })

  const stdio = opts.foregroundScripts ? 'inherit' : 'pipe'

  if (spec.type === 'directory' && !opts.ignoreScripts) {
    // prepack
    await runScript({
      ...opts,
      event: 'prepack',
      path: spec.fetchSpec,
      stdio,
      pkg: manifest,
    })
  }

  // packs tarball
  const tarball = await pacote.tarball(manifest._resolved, {
    ...opts,
    Arborist,
    integrity: manifest._integrity,
  })

  // check for explicit `false` so the default behavior is to skip writing to disk
  if (opts.dryRun === false) {
    const filename = `${manifest.name}-${manifest.version}.tgz`
      .replace(/^@/, '').replace(/\//, '-')
    const destination = path.resolve(opts.packDestination, filename)
    await writeFile(destination, tarball)
  }

  if (spec.type === 'directory' && !opts.ignoreScripts) {
    // postpack
    await runScript({
      ...opts,
      event: 'postpack',
      path: spec.fetchSpec,
      stdio,
      pkg: manifest,
      env: {
        npm_package_from: tarball.from,
        npm_package_resolved: tarball.resolved,
        npm_package_integrity: tarball.integrity,
      },
    })
  }

  return tarball

# libnpmpublish

[![npm version](https://img.shields.io/npm/v/libnpmpublish.svg)](https://npm.im/libnpmpublish)
[![license](https://img.shields.io/npm/l/libnpmpublish.svg)](https://npm.im/libnpmpublish)
[![CI - libnpmpublish](https://github.com/npm/cli/actions/workflows/ci-libnpmpublish.yml/badge.svg)](https://github.com/npm/cli/actions/workflows/ci-libnpmpublish.yml)

[`libnpmpublish`](https://github.com/npm/libnpmpublish) is a Node.js
library for programmatically publishing and unpublishing npm packages. Give
it a manifest as an object and a tarball as a Buffer, and it'll put them on
the registry for you.

## Table of Contents

* [Example](#example)
* [Install](#install)
* [API](#api)
  * [publish/unpublish opts](#opts)
  * [`publish()`](#publish)
  * [`unpublish()`](#unpublish)

## Example

```js
const { publish, unpublish } = require('libnpmpublish')
```

## Install

`$ npm install libnpmpublish`

### API

#### <a name="opts"></a> `opts` for `libnpmpublish` commands

`libnpmpublish` uses
[`npm-registry-fetch`](https://npm.im/npm-registry-fetch).  Most options
are passed through directly to that library, so please refer to [its own
`opts` documentation](http://npm.im/npm-registry-fetch#fetch-options) for
options that can be passed in.

A couple of options of note:

* `opts.defaultTag` - registers the published package with the given tag,
  defaults to `latest`.

* `opts.access` - tells the registry whether this package should be
  published as `public` or `restricted`. Only applies to scoped
  packages.  Defaults to `public`.

* `opts.token` - can be passed in and will be used as the authentication
  token for the registry. For other ways to pass in auth details, see the
  n-r-f docs.

* `opts.provenance` - when running in a supported CI environment, will trigger
  the generation of a signed provenance statement to be published alongside
  the package. Mutually exclusive with the `provenanceFile` option.

* `opts.provenanceFile` - specifies the path to an externally-generated
  provenance statement to be published alongside the package. Mutually
  exclusive with the `provenance` option. The specified file should be a
  [Sigstore Bundle](https://github.com/sigstore/protobuf-specs/blob/main/protos/sigstore_bundle.proto)
  containing a [DSSE](https://github.com/secure-systems-lab/dsse)-packaged
  provenance statement.

#### <a name="publish"></a> `> libpub.publish(manifest, tarData, [opts]) -> Promise`

Sends the package represented by the `manifest` and `tarData` to the
configured registry.

`manifest` should be the parsed `package.json` for the package being
published (which can also be the manifest pulled from a packument, a git
repo, tarball, etc.)

`tarData` is a `Buffer` of the tarball being published.

If `opts.npmVersion` is passed in, it will be used as the `_npmVersion`
field in the outgoing packument.  You may put your own user-agent string in
there to identify your publishes.

If `opts.algorithms` is passed in, it should be an array of hashing
algorithms to generate `integrity` hashes for. The default is `['sha512']`,
which means you end up with `dist.integrity = 'sha512-deadbeefbadc0ffee'`.
Any algorithm supported by your current node version is allowed -- npm
clients that do not support those algorithms will simply ignore the
unsupported hashes.

##### Example

```js
// note that pacote.manifest() and pacote.tarball() can also take
// any spec that npm can install.  a folder shown here, since that's
// far and away the most common use case.
const path = '/a/path/to/your/source/code'
const pacote = require('pacote') // see: http://npm.im/pacote
const manifest = await pacote.manifest(path)
const tarData = await pacote.tarball(path)
await libpub.publish(manifest, tarData, {
  npmVersion: 'my-pub-script@1.0.2',
  token: 'my-auth-token-here'
}, opts)
// Package has been published to the npm registry.
```

#### <a name="unpublish"></a> `> libpub.unpublish(spec, [opts]) -> Promise`

Unpublishes `spec` from the appropriate registry. The registry in question may
have its own limitations on unpublishing.

`spec` should be either a string, or a valid
[`npm-package-arg`](https://npm.im/npm-package-arg) parsed spec object. For
legacy compatibility reasons, only `tag` and `version` specs will work as
expected. `range` specs will fail silently in most cases.

##### Example

```js
await libpub.unpublish('lodash', { token: 'i-am-the-worst'})
//
// `lodash` has now been unpublished, along with all its versions
```

  publish: require('./publish.js'),

[`libnpmsearch`](https://github.com/npm/libnpmsearch) is a Node.js library for
programmatically accessing the npm search endpoint. It does **not** support
legacy search through `/-/all`.

## Table of Contents

* [Example](#example)
* [Install](#install)
* [Contributing](#contributing)
* [API](#api)
  * [search opts](#opts)
  * [`search()`](#search)
  * [`search.stream()`](#search-stream)

## Example

```js
const search = require('libnpmsearch')

console.log(await search('libnpm'))
=>
[
  {
    name: 'libnpm',
    description: 'programmatic npm API',
    ...etc
  },
  {
    name: 'libnpmsearch',
    description: 'Programmatic API for searching in npm and compatible registries',
    ...etc
  },
  ...more
]
```

## Install

`$ npm install libnpmsearch`

### API

#### <a name="opts"></a> `opts` for `libnpmsearch` commands

The following opts are used directly by `libnpmsearch` itself:

* `opts.limit` - Number of results to limit the query to. Default: 20
* `opts.from` - Offset number for results. Used with `opts.limit` for pagination. Default: 0
* `opts.detailed` - If true, returns an object with `package`, `score`, and `searchScore` fields, with `package` being what would usually be returned, and the other two containing details about how that package scored. Useful for UIs. Default: false
* `opts.sortBy` - Used as a shorthand to set `opts.quality`, `opts.maintenance`, and `opts.popularity` with values that prioritize each one. Should be one of `'optimal'`, `'quality'`, `'maintenance'`, or `'popularity'`. Default: `'optimal'`
* `opts.maintenance` - Decimal number between `0` and `1` that defines the weight of `maintenance` metrics when scoring and sorting packages. Default: `0.65` (same as `opts.sortBy: 'optimal'`)
* `opts.popularity` - Decimal number between `0` and `1` that defines the weight of `popularity` metrics when scoring and sorting packages. Default: `0.98` (same as `opts.sortBy: 'optimal'`)
* `opts.quality` - Decimal number between `0` and `1` that defines the weight of `quality` metrics when scoring and sorting packages. Default: `0.5` (same as `opts.sortBy: 'optimal'`)

`libnpmsearch` uses [`npm-registry-fetch`](https://npm.im/npm-registry-fetch).
Most options are passed through directly to that library, so please refer to
[its own `opts`
documentation](https://www.npmjs.com/package/npm-registry-fetch#fetch-options)
for options that can be passed in.

A couple of options of note for those in a hurry:

* `opts.token` - can be passed in and will be used as the authentication token for the registry. For other ways to pass in auth details, see the n-r-f docs.

#### <a name="search"></a> `> search(query, [opts]) -> Promise`

`query` must be either a String or an Array of search terms.

If `opts.limit` is provided, it will be sent to the API to constrain the number
of returned results. You may receive more, or fewer results, at the endpoint's
discretion.

The returned Promise resolved to an Array of search results with the following
format:

```js
{
  name: String,
  version: SemverString,
  description: String || null,
  maintainers: [
    {
      username: String,
      email: String
    },
    ...etc
  ] || null,
  keywords: [String] || null,
  date: Date || null
}
```

If `opts.limit` is provided, it will be sent to the API to constrain the number
of returned results. You may receive more, or fewer results, at the endpoint's
discretion.

For streamed results, see [`search.stream`](#search-stream).

##### Example

```javascript
await search('libnpm')
=>
[
  {
    name: 'libnpm',
    description: 'programmatic npm API',
    ...etc
  },
  {
    name: 'libnpmsearch',
    description: 'Programmatic API for searching in npm and compatible registries',
    ...etc
  },
  ...more
]
```

#### <a name="search-stream"></a> `> search.stream(query, [opts]) -> Stream`

`query` must be either a String or an Array of search terms.

If `opts.limit` is provided, it will be sent to the API to constrain the number
of returned results. You may receive more, or fewer results, at the endpoint's
discretion.

The returned Stream emits one entry per search result, with each entry having
the following format:

```js
{

[![license](https://img.shields.io/npm/l/libnpmteam.svg)](https://npm.im/libnpmteam)
[![CI - libnpmteam](https://github.com/npm/cli/actions/workflows/ci-libnpmteam.yml/badge.svg)](https://github.com/npm/cli/actions/workflows/ci-libnpmteam.yml)

[`libnpmteam`](https://github.com/npm/libnpmteam) is a Node.js
library that provides programmatic access to the guts of the npm CLI's `npm
team` command and its various subcommands.

## Example

```javascript
const team = require('libnpmteam')

// List all teams for the @npm org.
console.log(await team.lsTeams('npm'))
```

## Publishing
1. Manually create CHANGELOG.md file
1. Commit changes to CHANGELOG.md
    ```bash
    $ git commit -m "chore: updated CHANGELOG.md"
    ```
1. Run `npm version {newVersion}`
    ```bash
    # Example
    $ npm version patch
    # 1. Runs `coverage` and `lint` scripts
    # 2. Bumps package version; and **create commit/tag**
    # 3. Runs `npm publish`; publishing directory with **unpushed commit**
    # 4. Runs `git push origin --follow-tags`
    ```

### Install

`$ npm install libnpmteam`

### API

#### <a name="opts"></a> `opts` for `libnpmteam` commands

`libnpmteam` uses [`npm-registry-fetch`](https://npm.im/npm-registry-fetch).
All options are passed through directly to that library, so please refer to [its
own `opts`
documentation](https://www.npmjs.com/package/npm-registry-fetch#fetch-options)
for options that can be passed in.

A couple of options of note for those in a hurry:

* `opts.token` - can be passed in and will be used as the authentication token for the registry. For other ways to pass in auth details, see the n-r-f docs.
* `opts.otp` - certain operations will require an OTP token to be passed in. If a `libnpmteam` command fails with `err.code === EOTP`, please retry the request with `{otp: <2fa token>}`

#### <a name="create"></a> `> team.create(team, [opts]) -> Promise`

Creates a team named `team`. Team names use the format `@<scope>:<name>`, with
the `@` being optional.

Additionally, `opts.description` may be passed in to include a description.

##### Example

```javascript
await team.create('@npm:cli', {token: 'myregistrytoken'})
// The @npm:cli team now exists.
```

#### <a name="destroy"></a> `> team.destroy(team, [opts]) -> Promise`

Destroys a team named `team`. Team names use the format `@<scope>:<name>`, with
the `@` being optional.

##### Example

```javascript
await team.destroy('@npm:cli', {token: 'myregistrytoken'})
// The @npm:cli team has been destroyed.
```

#### <a name="add"></a> `> team.add(user, team, [opts]) -> Promise`

Adds `user` to `team`.

##### Example

```javascript
await team.add('zkat', '@npm:cli', {token: 'myregistrytoken'})
// @zkat now belongs to the @npm:cli team.
```

#### <a name="rm"></a> `> team.rm(user, team, [opts]) -> Promise`

Removes `user` from `team`.

##### Example

```javascript
await team.rm('zkat', '@npm:cli', {token: 'myregistrytoken'})
// @zkat is no longer part of the @npm:cli team.
```

#### <a name="ls-teams"></a> `> team.lsTeams(scope, [opts]) -> Promise`

Resolves to an array of team names belonging to `scope`.

##### Example

```javascript
await team.lsTeams('@npm', {token: 'myregistrytoken'})
=>
[
  'npm:cli',
  'npm:web',
  'npm:registry',
  'npm:developers'
]
```

#### <a name="ls-teams-stream"></a> `> team.lsTeams.stream(scope, [opts]) -> Stream`

Returns a stream of teams belonging to `scope`.

For a Promise-based version of these results, see [`team.lsTeams()`](#ls-teams).

##### Example

```javascript
for await (let team of team.lsTeams.stream('@npm', {token: 'myregistrytoken'})) {
  console.log(team)
}

// outputs
// npm:cli
// npm:web
// npm:registry
// npm:developers
```

#### <a name="ls-users"></a> `> team.lsUsers(team, [opts]) -> Promise`

Resolves to an array of usernames belonging to `team`.

For a streamed version of these results, see [`team.lsUsers.stream()`](#ls-users-stream).

##### Example

```javascript
await team.lsUsers('@npm:cli', {token: 'myregistrytoken'})
=>
[
  'iarna',
  'zkat'
]
```

#### <a name="ls-users-stream"></a> `> team.lsUsers.stream(team, [opts]) -> Stream`

Returns a stream of usernames belonging to `team`.

For a Promise-based version of these results, see [`team.lsUsers()`](#ls-users).

##### Example

```javascript
for await (let user of team.lsUsers.stream('@npm:cli', {token: 'myregistrytoken'})) {
  console.log(user)
}

// outputs
// iarna
// zkat
```

Library to do the things that 'npm version' does.

## USAGE

```js
const npmVersion = require('libnpmversion')

// argument can be one of:
// - any semver version string (set to that exact version)
// - 'major', 'minor', 'patch', 'pre{major,minor,patch}' (increment at
//   that value)
// - 'from-git' (set to the latest semver-lookin git tag - this skips
//   gitTagVersion, but will still sign if asked)
npmVersion(arg, {
  path: '/path/to/my/pkg', // defaults to cwd

  allowSameVersion: false, // allow tagging/etc to the current version
  preid: '', // when arg=='pre', define the prerelease string, like 'beta' etc.
  tagVersionPrefix: 'v', // tag as 'v1.2.3' when versioning to 1.2.3
  commitHooks: true, // default true, run git commit hooks, default true
  gitTagVersion: true, // default true, tag the version
  signGitCommit: false, // default false, gpg sign the git commit
  signGitTag: false, // default false, gpg sign the git tag
  force: false, // push forward recklessly if any problems happen
  ignoreScripts: false, // do not run pre/post/version lifecycle scripts
  scriptShell: '/bin/bash', // shell to run lifecycle scripts in
  message: 'v%s', // message for tag and commit, replace %s with the version
}).then(newVersion => {
  console.error('version updated!', newVersion)
})
```

## Description

Run this in a package directory to bump the version and write the new data
back to `package.json`, `package-lock.json`, and, if present,
`npm-shrinkwrap.json`.

The `newversion` argument should be a valid semver string, a valid second
argument to [semver.inc](https://github.com/npm/node-semver#functions) (one
of `patch`, `minor`, `major`, `prepatch`, `preminor`, `premajor`,
`prerelease`), or `from-git`. In the second case, the existing version will
be incremented by 1 in the specified field.  `from-git` will try to read
the latest git tag, and use that as the new npm version.

If run in a git repo, it will also create a version commit and tag.  This
behavior is controlled by `gitTagVersion` (see below), and can be
disabled by setting `gitTagVersion: false` in the options.
It will fail if the working directory is not clean, unless `force: true` is
set.

If supplied with a `message` string option, it will
use it as a commit message when creating a version commit.  If the
`message` option contains `%s` then that will be replaced with the
resulting version number.

If the `signGitTag` option is set, then the tag will be signed using
the `-s` flag to git.  Note that you must have a default GPG key set up in
your git config for this to work properly.

If `preversion`, `version`, or `postversion` are in the `scripts` property
of the package.json, they will be executed in the appropriate sequence.

The exact order of execution is as follows:

1. Check to make sure the git working directory is clean before we get
   started.  Your scripts may add files to the commit in future steps.
   This step is skipped if the `force` flag is set.
2. Run the `preversion` script.  These scripts have access to the old
   `version` in package.json.  A typical use would be running your full
   test suite before deploying.  Any files you want added to the commit
   should be explicitly added using `git add`.
3. Bump `version` in `package.json` as requested (`patch`, `minor`,
   `major`, explicit version number, etc).
4. Run the `version` script. These scripts have access to the new `version`
   in package.json (so they can incorporate it into file headers in
   generated files for example).  Again, scripts should explicitly add
   generated files to the commit using `git add`.
5. Commit and tag.
6. Run the `postversion` script. Use it to clean up the file system or
   automatically push the commit and/or tag.

Take the following example:

```json
{
  "scripts": {
    "preversion": "npm test",
    "version": "npm run build && git add -A dist",
    "postversion": "git push && git push --tags && rm -rf build/temp"
  }
}
```

This runs all your tests, and proceeds only if they pass. Then runs your
`build` script, and adds everything in the `dist` directory to the commit.
After the commit, it pushes the new commit and tag up to the server, and
deletes the `build/temp` directory.

## API

### `npmVersion(newversion, options = {}) -> Promise<String>`

Do the things.  Returns a promise that resolves to the new version if
all is well, or rejects if any errors are encountered.

### Options

#### `path` String

The path to the package being versionified.  Defaults to process.cwd().

#### `allowSameVersion` Boolean

Allow setting the version to the current version in package.json.  Default
`false`.

#### `preid` String
When the `newversion` is pre, premajor, preminor, or prepatch, this
defines the prerelease string, like 'beta' etc.

#### `tagVersionPrefix` String

The prefix to add to the raw semver string for the tag name.  Defaults to
`'v'`.  (So, by default it tags as 'v1.2.3' when versioning to 1.2.3.)

#### `commitHooks` Boolean

Run git commit hooks.  Default true.

#### `gitTagVersion` Boolean

Tag the version, default true.

#### `signGitCommit` Boolean

GPG sign the git commit.  Default `false`.

#### `signGitTag` Boolean

GPG sign the git tag.  Default `false`.

#### `force` Boolean

Push forward recklessly if any problems happen.  Default `false`.

#### `ignoreScripts` Boolean

Do not run pre/post/version lifecycle scripts.  Default `false`.

#### `scriptShell` String

Path to the shell, which should execute the lifecycle scripts.  Defaults to `/bin/sh` on unix, or `cmd.exe` on windows.

#### `message` String

The message for the git commit and annotated git tag that are created.

    // the BODY of the regexp, along with the start/end portions suitable
    // for binding the start/end in either a joined full-path makeRe context
    // (where we bind to (^|/), or a standalone matchPart context (where
    // we bind to ^, and not /).  Otherwise slashes get duped!
    //
    // In part-matching mode, the start is:
    // - if not isStart: nothing
    // - if traversal possible, but not allowed: ^(?!\.\.?$)
    // - if dots allowed or not possible: ^
    // - if dots possible and not allowed: ^(?!\.)
    // end is:
    // - if not isEnd(): nothing
    // - else: $
    //
    // In full-path matching mode, we put the slash at the START of the
    // pattern, so start is:
    // - if first pattern: same as part-matching mode
    // - if not isStart(): nothing
    // - if traversal possible, but not allowed: /(?!\.\.?(?:$|/))
    // - if dots allowed or not possible: /
    // - if dots possible and not allowed: /(?!\.)
    // end is:
    // - if last pattern, same as part-matching mode
    // - else nothing
    //
    // Always put the (?:$|/) on negated tails, though, because that has to be
    // there to bind the end of the negated pattern portion, and it's easier to
    // just stick it in now rather than try to inject it later in the middle of
    // the pattern.
    //
    // We can just always return the same end, and leave it up to the caller
    // to know whether it's going to be used joined or in parts.
    // And, if the start is adjusted slightly, can do the same there:
    // - if not isStart: nothing
    // - if traversal possible, but not allowed: (?:/|^)(?!\.\.?$)
    // - if dots allowed or not possible: (?:/|^)
    // - if dots possible and not allowed: (?:/|^)(?!\.)
    //
    // But it's better to have a simpler binding without a conditional, for
    // performance, so probably better to return both start options.
    //
    // Then the caller just ignores the end if it's not the first pattern,
    // and the start always gets applied.
    //
    // But that's always going to be $ if it's the ending pattern, or nothing,
    // so the caller can just attach $ at the end of the pattern when building.
    //
    // So the todo is:
    // - better detect what kind of start is needed
    // - return both flavors of starting pattern
    // - attach $ at the end of the pattern when creating the actual RegExp
    //
    // Ah, but wait, no, that all only applies to the root when the first pattern
    // is not an extglob. If the first pattern IS an extglob, then we need all
    // that dot prevention biz to live in the extglob portions, because eg
    // +(*|.x*) can match .xy but not .yx.
    //
    // So, return the two flavors if it's #root and the first child is not an
    // AST, otherwise leave it to the child AST to handle it, and there,
    // use the (?:^|/) style of start binding.
    //
    // Even simplified further:
    // - Since the start for a join is eg /(?!\.) and the start for a part
    // is ^(?!\.), we can just prepend (?!\.) to the pattern (either root
    // or start or whatever) and prepend ^ or / at the Regexp construction.

    // (where we bind to (^|/), or a standalone matchPart context (where
    // we bind to ^, and not /).  Otherwise slashes get duped!
    //
    // In part-matching mode, the start is:
    // - if not isStart: nothing
    // - if traversal possible, but not allowed: ^(?!\.\.?$)
    // - if dots allowed or not possible: ^
    // - if dots possible and not allowed: ^(?!\.)
    // end is:
    // - if not isEnd(): nothing
    // - else: $
    //
    // In full-path matching mode, we put the slash at the START of the
    // pattern, so start is:
    // - if first pattern: same as part-matching mode
    // - if not isStart(): nothing
    // - if traversal possible, but not allowed: /(?!\.\.?(?:$|/))
    // - if dots allowed or not possible: /
    // - if dots possible and not allowed: /(?!\.)
    // end is:
    // - if last pattern, same as part-matching mode
    // - else nothing
    //
    // Always put the (?:$|/) on negated tails, though, because that has to be
    // there to bind the end of the negated pattern portion, and it's easier to
    // just stick it in now rather than try to inject it later in the middle of
    // the pattern.
    //
    // We can just always return the same end, and leave it up to the caller
    // to know whether it's going to be used joined or in parts.
    // And, if the start is adjusted slightly, can do the same there:
    // - if not isStart: nothing
    // - if traversal possible, but not allowed: (?:/|^)(?!\.\.?$)
    // - if dots allowed or not possible: (?:/|^)
    // - if dots possible and not allowed: (?:/|^)(?!\.)
    //
    // But it's better to have a simpler binding without a conditional, for
    // performance, so probably better to return both start options.
    //
    // Then the caller just ignores the end if it's not the first pattern,
    // and the start always gets applied.
    //
    // But that's always going to be $ if it's the ending pattern, or nothing,
    // so the caller can just attach $ at the end of the pattern when building.
    //
    // So the todo is:
    // - better detect what kind of start is needed
    // - return both flavors of starting pattern
    // - attach $ at the end of the pattern when creating the actual RegExp
    //
    // Ah, but wait, no, that all only applies to the root when the first pattern
    // is not an extglob. If the first pattern IS an extglob, then we need all
    // that dot prevention biz to live in the extglob portions, because eg
    // +(*|.x*) can match .xy but not .yx.
    //
    // So, return the two flavors if it's #root and the first child is not an
    // AST, otherwise leave it to the child AST to handle it, and there,
    // use the (?:^|/) style of start binding.
    //
    // Even simplified further:
    // - Since the start for a join is eg /(?!\.) and the start for a part
    // is ^(?!\.), we can just prepend (?!\.) to the pattern (either root
    // or start or whatever) and prepend ^ or / at the Regexp construction.

# mkdirp

Like `mkdir -p`, but in Node.js!

Now with a modern API and no\* bugs!

<small>\* may contain some bugs</small>

# example

## pow.js

```js
const mkdirp = require('mkdirp')

// return value is a Promise resolving to the first directory created
mkdirp('/tmp/foo/bar/baz').then(made =>
  console.log(`made directories, starting with ${made}`))
```

Output (where `/tmp/foo` already exists)

```
made directories, starting with /tmp/foo/bar
```

Or, if you don't have time to wait around for promises:

```js
const mkdirp = require('mkdirp')

// return value is the first directory created
const made = mkdirp.sync('/tmp/foo/bar/baz')
console.log(`made directories, starting with ${made}`)
```

And now /tmp/foo/bar/baz exists, huzzah!

# methods

```js
const mkdirp = require('mkdirp')
```

## mkdirp(dir, [opts]) -> Promise<String | undefined>

Create a new directory and any necessary subdirectories at `dir` with octal
permission string `opts.mode`. If `opts` is a string or number, it will be
treated as the `opts.mode`.

If `opts.mode` isn't specified, it defaults to `0o777 &
(~process.umask())`.

Promise resolves to first directory `made` that had to be created, or
`undefined` if everything already exists.  Promise rejects if any errors
are encountered.  Note that, in the case of promise rejection, some
directories _may_ have been created, as recursive directory creation is not
an atomic operation.

You can optionally pass in an alternate `fs` implementation by passing in
`opts.fs`. Your implementation should have `opts.fs.mkdir(path, opts, cb)`
and `opts.fs.stat(path, cb)`.

You can also override just one or the other of `mkdir` and `stat` by
passing in `opts.stat` or `opts.mkdir`, or providing an `fs` option that
only overrides one of these.

## mkdirp.sync(dir, opts) -> String|null

Synchronously create a new directory and any necessary subdirectories at
`dir` with octal permission string `opts.mode`. If `opts` is a string or
number, it will be treated as the `opts.mode`.

If `opts.mode` isn't specified, it defaults to `0o777 &
(~process.umask())`.

Returns the first directory that had to be created, or undefined if
everything already exists.

You can optionally pass in an alternate `fs` implementation by passing in
`opts.fs`. Your implementation should have `opts.fs.mkdirSync(path, mode)`
and `opts.fs.statSync(path)`.

You can also override just one or the other of `mkdirSync` and `statSync`
by passing in `opts.statSync` or `opts.mkdirSync`, or providing an `fs`
option that only overrides one of these.

## mkdirp.manual, mkdirp.manualSync

Use the manual implementation (not the native one).  This is the default
when the native implementation is not available or the stat/mkdir
implementation is overridden.

## mkdirp.native, mkdirp.nativeSync

Use the native implementation (not the manual one).  This is the default
when the native implementation is available and stat/mkdir are not
overridden.

# implementation

On Node.js v10.12.0 and above, use the native `fs.mkdir(p,
{recursive:true})` option, unless `fs.mkdir`/`fs.mkdirSync` has been
overridden by an option.

## native implementation

- If the path is a root directory, then pass it to the underlying
  implementation and return the result/error.  (In this case, it'll either
  succeed or fail, but we aren't actually creating any dirs.)
- Walk up the path statting each directory, to find the first path that
  will be created, `made`.
- Call `fs.mkdir(path, { recursive: true })` (or `fs.mkdirSync`)
- If error, raise it to the caller.
- Return `made`.

## manual implementation

- Call underlying `fs.mkdir` implementation, with `recursive: false`
- If error:
  - If path is a root directory, raise to the caller and do not handle it
  - If ENOENT, mkdirp parent dir, store result as `made`
  - stat(path)
    - If error, raise original `mkdir` error
    - If directory, return `made`
    - Else, raise original `mkdir` error
- else
  - return `undefined` if a root dir, or `made` if set, or `path`

## windows vs unix caveat

On Windows file systems, attempts to create a root directory (ie, a drive
letter or root UNC path) will fail.  If the root directory exists, then it
will fail with `EPERM`.  If the root directory does not exist, then it will
fail with `ENOENT`.

On posix file systems, attempts to create a root directory (in recursive
mode) will succeed silently, as it is treated like just another directory
that already exists.  (In non-recursive mode, of course, it fails with
`EEXIST`.)

In order to preserve this system-specific behavior (and because it's not as
if we can create the parent of a root directory anyway), attempts to create
a root directory are passed directly to the `fs` implementation, and any
errors encountered are not handled.

## native error caveat

The native implementation (as of at least Node.js v13.4.0) does not provide
appropriate errors in some cases (see
[nodejs/node#31481](https://github.com/nodejs/node/issues/31481) and
[nodejs/node#28015](https://github.com/nodejs/node/issues/28015)).

In order to work around this issue, the native implementation will fall
back to the manual implementation if an `ENOENT` error is encountered.

# choosing a recursive mkdir implementation

There are a few to choose from!  Use the one that suits your needs best :D

## use `fs.mkdir(path, {recursive: true}, cb)` if:

- You wish to optimize performance even at the expense of other factors.
- You don't need to know the first dir created.
- You are ok with getting `ENOENT` as the error when some other problem is
  the actual cause.
- You can limit your platforms to Node.js v10.12 and above.
- You're ok with using callbacks instead of promises.
- You don't need/want a CLI.
- You don't need to override the `fs` methods in use.

## use this module (mkdirp 1.x) if:

- You need to know the first directory that was created.
- You wish to use the native implementation if available, but fall back
  when it's not.
- You prefer promise-returning APIs to callback-taking APIs.
- You want more useful error messages than the native recursive mkdir
  provides (at least as of Node.js v13.4), and are ok with re-trying on
  `ENOENT` to achieve this.
- You need (or at least, are ok with) a CLI.
- You need to override the `fs` methods in use.

## use [`make-dir`](http://npm.im/make-dir) if:

- You do not need to know the first dir created (and wish to save a few
  `stat` calls when using the native implementation for this reason).
- You wish to use the native implementation if available, but fall back
  when it's not.
- You prefer promise-returning APIs to callback-taking APIs.
- You are ok with occasionally getting `ENOENT` errors for failures that
  are actually related to something other than a missing file system entry.
- You don't need/want a CLI.
- You need to override the `fs` methods in use.

## use mkdirp 0.x if:

- You need to know the first directory that was created.
- You need (or at least, are ok with) a CLI.
- You need to override the `fs` methods in use.
- You're ok with using callbacks instead of promises.
- You are not running on Windows, where the root-level ENOENT errors can
  lead to infinite regress.
- You think vinyl just sounds warmer and richer for some weird reason.
- You are supporting truly ancient Node.js versions, before even the advent
  of a `Promise` language primitive.  (Please don't.  You deserve better.)

# cli

This package also ships with a `mkdirp` command.

```
$ mkdirp -h

usage: mkdirp [DIR1,DIR2..] {OPTIONS}

  Create each supplied directory including any necessary parent directories
  that don't yet exist.

  If the directory already exists, do nothing.

OPTIONS are:

  -m<mode>       If a directory needs to be created, set the mode as an octal
  --mode=<mode>  permission string.

  -v --version   Print the mkdirp version number

  -h --help      Print this helpful banner

  -p --print     Print the first directories created for each path provided

  --manual       Use manual implementation, even if native is available
```

# install

With [npm](http://npmjs.org) do:

```
npm install mkdirp
```

to get the library locally, or

```
npm install -g mkdirp
```

to get the command everywhere, or

```
npx mkdirp ...
```

to run the command without installing it globally.

# platform support

This module works on node v8, but only v10 and above are officially
supported, as Node v8 reached its LTS end of life 2020-01-01, which is in
the past, as of this writing.

## [10.0.0](https://www.github.com/nodejs/node-gyp/compare/v9.4.0...v10.0.0) (2023-10-28)


### ⚠ BREAKING CHANGES

* use .npmignore file to limit which files are published (#2921)
* the `Gyp` class exported is now created using ECMAScript classes and therefore might have small differences to classes that were previously created with `util.inherits`.
* All internal functions have been coverted to return promises and no longer accept callbacks. This is not a breaking change for users but may be breaking to consumers of `node-gyp` if you are requiring internal functions directly.
* `node-gyp` now supports node `^16.14.0 || >=18.0.0`

### Features

* convert all internal functions to async/await ([355622f](https://www.github.com/nodejs/node-gyp/commit/355622f4aac3bd3056b9e03aac5fa2f42a4b3576))

* use fs/promises in favor of fs.promises ([4a50fe3](https://www.github.com/nodejs/node-gyp/commit/4a50fe31574217c4b2a798fc72b19947a64ceea1))

## v7.1.1 2020-10-15

This release restores the location of shared library builds to the pre-v7
location. In v7.0.0 until this release, shared library outputs were placed
in a lib.target subdirectory inside the build/{Release,Debug} directory for
builds using `make` (Linux, etc.). This is inconsistent with macOS (Xcode)
behavior and previous node-gyp behavior so has been reverted.
We consider this a bug-fix rather than semver-major change.

# `node-gyp` - Node.js native addon build tool

[![Build Status](https://github.com/nodejs/node-gyp/workflows/Tests/badge.svg?branch=main)](https://github.com/nodejs/node-gyp/actions?query=workflow%3ATests+branch%3Amain)
![npm](https://img.shields.io/npm/dm/node-gyp)

`node-gyp` is a cross-platform command-line tool written in Node.js for
compiling native addon modules for Node.js. It contains a vendored copy of the
[gyp-next](https://github.com/nodejs/gyp-next) project that was previously used
by the Chromium team and extended to support the development of Node.js native
addons.

Note that `node-gyp` is _not_ used to build Node.js itself.

All current and LTS target versions of Node.js are supported. Depending on what version of Node.js is actually installed on your system
`node-gyp` downloads the necessary development files or headers for the target version. List of stable Node.js versions can be found on [Node.js website](https://nodejs.org/en/about/previous-releases).

## Features

 * The same build commands work on any of the supported platforms
 * Supports the targeting of different versions of Node.js

## Installation

> [!Important]
> Python >= v3.12 requires `node-gyp` >= v10

You can install `node-gyp` using `npm`:

``` bash
npm install -g node-gyp
```

Depending on your operating system, you will need to install:

### On Unix

   * [A supported version of Python](https://devguide.python.org/versions/)
   * `make`
   * A proper C/C++ compiler toolchain, like [GCC](https://gcc.gnu.org)

### On macOS

   * [A supported version of Python](https://devguide.python.org/versions/)
   * `Xcode Command Line Tools` which will install `clang`, `clang++`, and `make`.
     * Install the `Xcode Command Line Tools` standalone by running `xcode-select --install`. -- OR --
     * Alternatively, if you already have the [full Xcode installed](https://developer.apple.com/xcode/download/), you can install the Command Line Tools under the menu `Xcode -> Open Developer Tool -> More Developer Tools...`.


### On Windows

Install tools with [Chocolatey](https://chocolatey.org):
``` bash
choco install python visualstudio2022-workload-vctools -y
```

Or install and configure Python and Visual Studio tools manually:

  * Install the current [version of Python](https://devguide.python.org/versions/) from the
  [Microsoft Store](https://apps.microsoft.com/store/search?publisher=Python+Software+Foundation).

   * Install Visual C++ Build Environment: For Visual Studio 2019 or later, use the `Desktop development with C++` workload from [Visual Studio Community](https://visualstudio.microsoft.com/thank-you-downloading-visual-studio/?sku=Community).  For a version older than Visual Studio 2019, install [Visual Studio Build Tools](https://visualstudio.microsoft.com/thank-you-downloading-visual-studio/?sku=BuildTools) with the `Visual C++ build tools` option.

   If the above steps didn't work for you, please visit [Microsoft's Node.js Guidelines for Windows](https://github.com/Microsoft/nodejs-guidelines/blob/master/windows-environment.md#compiling-native-addon-modules) for additional tips.

   To target native ARM64 Node.js on Windows on ARM, add the components "Visual C++ compilers and libraries for ARM64" and "Visual C++ ATL for ARM64".

   To use the native ARM64 C++ compiler on Windows on ARM, ensure that you have Visual Studio 2022 [17.4 or later](https://devblogs.microsoft.com/visualstudio/arm64-visual-studio-is-officially-here/) installed.

It's advised to install following Powershell module: [VSSetup](https://github.com/microsoft/vssetup.powershell) using `Install-Module VSSetup -Scope CurrentUser`.
This will make Visual Studio detection logic to use more flexible and accessible method, avoiding Powershell's `ConstrainedLanguage` mode.

### Configuring Python Dependency

`node-gyp` requires that you have installed a [supported version of Python](https://devguide.python.org/versions/).
If you have multiple versions of Python installed, you can identify which version
`node-gyp` should use in one of the following ways:

1. by setting the `--python` command-line option, e.g.:

``` bash
node-gyp <command> --python /path/to/executable/python
```

2. If `node-gyp` is called by way of `npm`, *and* you have multiple versions of
Python installed, then you can set the `npm_config_python` environment variable
to the appropriate path:
``` bash
export npm_config_python=/path/to/executable/python
```
&nbsp;&nbsp;&nbsp;&nbsp;Or on Windows:
```console
py --list-paths  # To see the installed Python versions
set npm_config_python=C:\path\to\python.exe  # CMD
$Env:npm_config_python="C:\path\to\python.exe"  # PowerShell
```

3. If the `PYTHON` environment variable is set to the path of a Python executable,
then that version will be used if it is a supported version.

4. If the `NODE_GYP_FORCE_PYTHON` environment variable is set to the path of a
Python executable, it will be used instead of any of the other configured or
built-in Python search paths. If it's not a compatible version, no further
searching will be done.

### Build for Third Party Node.js Runtimes

When building modules for third-party Node.js runtimes like Electron, which have
different build configurations from the official Node.js distribution, you
should use `--dist-url` or `--nodedir` flags to specify the headers of the
runtime to build for.

Also when `--dist-url` or `--nodedir` flags are passed, node-gyp will use the
`config.gypi` shipped in the headers distribution to generate build
configurations, which is different from the default mode that would use the
`process.config` object of the running Node.js instance.

Some old versions of Electron shipped malformed `config.gypi` in their headers
distributions, and you might need to pass `--force-process-config` to node-gyp
to work around configuration errors.

## How to Use

To compile your native addon first go to its root directory:

``` bash
cd my_node_addon
```

The next step is to generate the appropriate project build files for the current
platform. Use `configure` for that:

``` bash
node-gyp configure
```

Auto-detection fails for Visual C++ Build Tools 2015, so `--msvs_version=2015`
needs to be added (not needed when run by npm as configured above):
``` bash
node-gyp configure --msvs_version=2015
```

__Note__: The `configure` step looks for a `binding.gyp` file in the current
directory to process. See below for instructions on creating a `binding.gyp` file.

Now you will have either a `Makefile` (on Unix platforms) or a `vcxproj` file
(on Windows) in the `build/` directory. Next, invoke the `build` command:

``` bash
node-gyp build
```

Now you have your compiled `.node` bindings file! The compiled bindings end up
in `build/Debug/` or `build/Release/`, depending on the build mode. At this point,
you can require the `.node` file with Node.js and run your tests!

__Note:__ To create a _Debug_ build of the bindings file, pass the `--debug` (or
`-d`) switch when running either the `configure`, `build` or `rebuild` commands.

## The `binding.gyp` file

A `binding.gyp` file describes the configuration to build your module, in a
JSON-like format. This file gets placed in the root of your package, alongside
`package.json`.

A barebones `gyp` file appropriate for building a Node.js addon could look like:

```python
{
  "targets": [
    {
      "target_name": "binding",
      "sources": [ "src/binding.cc" ]
    }
  ]
}
```

## Further reading

## Configuration

### Environment variables

Use the form `npm_config_OPTION_NAME` for any of the command options listed
above (dashes in option names should be replaced by underscores).

For example, to set `devdir` equal to `/tmp/.gyp`, you would:

Run this on Unix:

```bash
export npm_config_devdir=/tmp/.gyp
```

Or this on Windows:

```console
set npm_config_devdir=c:\temp\.gyp
```

### `npm` configuration for npm versions before v9

Use the form `OPTION_NAME` for any of the command options listed above.

For example, to set `devdir` equal to `/tmp/.gyp`, you would run:

```bash
npm config set [--global] devdir /tmp/.gyp
```

**Note:** Configuration set via `npm` will only be used when `node-gyp`
is run via `npm`, not when `node-gyp` is run directly.

# vs. CMake

GYP was originally created to generate native IDE project files (Visual Studio, Xcode) for building [Chromium](http://www.chromim.org).

The functionality of GYP is very similar to the [CMake](http://www.cmake.org)
build tool.  Bradley Nelson wrote up the following description of why the team
created GYP instead of using CMake.  The text below is copied from
http://www.mail-archive.com/webkit-dev@lists.webkit.org/msg11029.html

Re: [webkit-dev] CMake as a build system?
Bradley Nelson
Mon, 19 Apr 2010 22:38:30 -0700

Here's the innards of an email with a laundry list of stuff I came up with a
while back on the gyp-developers list in response to Mike Craddick regarding
what motivated gyp's development, since we were aware of cmake at the time
(we'd even started a speculative port):


I did an exploratory port of portions of Chromium to cmake (I think I got as
far as net, base, sandbox, and part of webkit).
There were a number of motivations, not all of which would apply to other
projects. Also, some of the design of gyp was informed by experience at
Google with large projects built wholly from source, leading to features
absent from cmake, but not strictly required for Chromium.

1. Ability to incrementally transition on Windows. It took us about 6 months
to switch fully to gyp. Previous attempts to move to scons had taken a long
time and failed, due to the requirement to transition while in flight. For a
substantial period of time, we had a hybrid of checked in vcproj and gyp generated
vcproj. To this day we still have a good number of GUIDs pinned in the gyp files,
because different parts of our release pipeline have leftover assumptions
regarding manipulating the raw sln/vcprojs. This transition occurred from
the bottom up, largely because modules like base were easier to convert, and
had a lower churn rate. During early stages of the transition, the majority
of the team wasn't even aware they were using gyp, as it integrated into
their existing workflow, and only affected modules that had been converted.

2. Generation of a more 'normal' vcproj file. Gyp attempts, particularly on
Windows, to generate vcprojs which resemble hand generated projects. It
doesn't generate any Makefile type projects, but instead produces msvs
Custom Build Steps and Custom Build Rules. This makes the resulting projects
easier to understand from the IDE and avoids parts of the IDE that simply
don't function correctly if you use Makefile projects. Our early hope with
gyp was to support the least common denominator of features present in each
of the platform specific project file formats, rather than falling back on
generated Makefiles/shell scripts to emulate some common abstraction. CMake by
comparison makes a good faith attempt to use native project features, but
falls back on generated scripts in order to preserve the same semantics on
each platforms.

3. Abstraction on the level of project settings, rather than command line
flags. In gyp's syntax you can add nearly any option present in a hand
generated xcode/vcproj file. This allows you to use abstractions built into
the IDEs rather than reverse engineering them possibly incorrectly for
things like: manifest generation, precompiled headers, bundle generation.
When somebody wants to use a particular menu option from msvs, I'm able to
do a web search on the name of the setting from the IDE and provide them
with a gyp stanza that does the equivalent. In many cases, not all project
file constructs correspond to command line flags.

4. Strong notion of module public/private interface. Gyp allows targets to
publish a set of direct_dependent_settings, specifying things like
include_dirs, defines, platforms specific settings, etc. This means that
when module A depends on module B, it automatically acquires the right build
settings without module A being filled with assumptions/knowledge of exactly
how module B is built. Additionally, all of the transitive dependencies of
module B are pulled in. This avoids their being a single top level view of
the project, rather each gyp file expresses knowledge about its immediate
neighbors. This keep local knowledge local. CMake effectively has a large
shared global namespace.

5. Cross platform generation. CMake is not able to generate all project
files on all platforms. For example xcode projects cannot be generated from
windows (cmake uses mac specific libraries to do project generation). This
means that for instance generating a tarball containing pregenerated
projects for all platforms is hard with Cmake (requires distribution to
several machine types).

6. Gyp has rudimentary cross compile support. Currently we've added enough
functionality to gyp to support x86 -> arm cross compiles. Last I checked
this functionality wasn't present in cmake. (This occurred later).


That being said there are a number of drawbacks currently to gyp:

1. Because platform specific settings are expressed at the project file
level (rather than the command line level). Settings which might otherwise
be shared in common between platforms (flags to gcc on mac/linux), end up
being repeated twice. Though in fairness there is actually less sharing here
than you'd think. include_dirs and defines actually represent 90% of what
can be typically shared.

2. CMake may be more mature, having been applied to a broader range of
projects. There a number of 'tool modules' for cmake, which are shared in a
common community.

3. gyp currently makes some nasty assumptions about the availability of
chromium's hermetic copy of cygwin on windows. This causes you to either
have to special case a number of rules, or swallow this copy of cygwin as a
build time dependency.

4. CMake includes a fairly readable imperative language. Currently Gyp has a
somewhat poorly specified declarative language (variable expansion happens
in sometimes weird and counter-intuitive ways). In fairness though, gyp assumes
that external python scripts can be used as an escape hatch. Also gyp avoids
a lot of the things you'd need imperative code for, by having a nice target
settings publication mechanism.

5. (Feature/drawback depending on personal preference). Gyp's syntax is
DEEPLY nested. It suffers from all of Lisp's advantages and drawbacks.

# Hacking

## Getting the sources

Git is required to hack on anything, you can set up a git clone of GYP
as follows:

```
mkdir foo
cd foo
git clone git@github.com:nodejs/gyp-next.git
cd gyp
```

(this will clone gyp underneath it into `foo/gyp`.
`foo` can be any directory name you want. Once you've done that,
you can use the repo like anything other Git repo.

## Testing your change

GYP has a suite of tests which you can run with the provided test driver
to make sure your changes aren't breaking anything important.

You run the test driver with e.g.

``` sh
$ python -m pip install --upgrade pip setuptools
$ pip install --editable ".[dev]"
$ python -m pytest
```

See [Testing](Testing.md) for more details on the test framework.

Note that it can be handy to look at the project files output by the tests
to diagnose problems. The easiest way to do that is by kindly asking the
test driver to leave the temporary directories it creates in-place.
This is done by setting the enviroment variable "PRESERVE", e.g.

```
set PRESERVE=all     # On Windows
export PRESERVE=all  # On saner platforms.
```

## Reviewing your change

All changes to GYP must be code reviewed before submission.
# Input Format Reference

## Primitive Types

The following primitive types are found within input files:

  * String values, which may be represented by enclosing them in
    `'single quotes'` or `"double quotes"`.  By convention, single
    quotes are used.
  * Integer values, which are represented in decimal without any special
    decoration.  Integers are fairly rare in input files, but have a few
    applications in boolean contexts, where the convention is to
    represent true values with `1` and false with `0`.
  * Lists, which are represented as a sequence of items separated by
    commas (`,`) within square brackets (`[` and `]`).  A list may
    contain any other primitive types, including other lists.
    Generally, each item of a list must be of the same type as all other
    items in the list, but in some cases (such as within `conditions`
    sections), the list structure is more tightly specified.  A trailing
    comma is permitted.

    This example list contains three string values.

      ```
      [ 'Generate', 'Your', 'Projects', ]
      ```

  * Dictionaries, which map keys to values.  All keys are strings.
    Values may be of any other primitive type, including other
    dictionaries.  A dictionary is enclosed within curly braces (`{` and
    `}`).  Keys precede values, separated by a colon (`:`).  Successive
    dictionary entries are separated by commas (`,`).  A trailing comma
    is permitted.  It is an error for keys to be duplicated within a
    single dictionary as written in an input file, although keys may
    replace other keys during [merging](#Merging).

    This example dictionary maps each of three keys to different values.

      ```
      {
        'inputs': ['version.c.in'],
        'outputs': ['version.c'],
        'process_outputs_as_sources': 1,
      }
      ```

## Overall Structure

A GYP input file is organized as structured data.  At the root scope of
each `.gyp` or `.gypi` (include) file is a dictionary.  The keys and
values of this dictionary, along with any descendants contained within
the values, provide the data contained within the file.  This data is
given meaning by interpreting specific key names and their associated
values in specific ways (see [Settings Keys](#Settings_Keys)).

### Comments (#)

Within an input file, a comment is introduced by a pound sign (`#`) not
within a string.  Any text following the pound sign, up until the end of
the line, is treated as a comment.

#### Example

```
{
  'school_supplies': [
    'Marble composition book',
    'Sharp #2 pencil',
    'Safety scissors',  # You still shouldn't run with these
  ],
}
```

In this example, the # in `'Sharp #2 pencil'` is not taken as
introducing a comment because it occurs within a string, but the text
after `'Safety scissors'` is treated as a comment having no impact on
the data within the file.

## Merging

### Merge Basics (=, ?, +)

Many operations on GYP input files occurs by merging dictionary and list
items together.  During merge operations, it is important to recognize
the distinction between source and destination values.  Items from the
source value are merged into the destination, which leaves the source
unchanged and the destination modified by the source.  A dictionary may
only be merged into another dictionary, and a list may only be merged
into another list.

  * When merging a dictionary, for each key in the source:
    * If the key does not exist in the destination dictionary, insert it
      and copy the associated value directly.
    * If the key does exist:
      * If the associated value is a dictionary, perform the dictionary
        merging procedure using the source's and destination's value
        dictionaries.
      * If the associated value is a list, perform the list merging
        procedure using the source's and destination's value lists.
      * If the associated value is a string or integer, the destination
        value is replaced by the source value.
  * When merging a list, merge according to the suffix appended to the
    key name, if the list is a value within a dictionary.
    * If the key ends with an equals sign (`=`), the policy is for the
      source list to completely replace the destination list if it
      exists.  _Mnemonic: `=` for assignment._
    * If the key ends with a question mark (`?`), the policy is for the
      source list to be set as the destination list only if the key is
      not already present in the destination.  _Mnemonic: `?` for
      conditional assignment_.
    * If the key ends with a plus sign (`+`), the policy is for the
      source list contents to be prepended to the destination list.
      _Mnemonic: `+` for addition or concatenation._
    * If the list key is undecorated, the policy is for the source list
      contents to be appended to the destination list.  This is the
      default list merge policy.

#### Example

Source dictionary:

```
{
  'include_dirs+': [
    'shared_stuff/public',
  ],
  'link_settings': {
    'libraries': [
      '-lshared_stuff',
    ],
  },
  'test': 1,
}
```

Destination dictionary:

```
{
  'target_name': 'hello',
  'sources': [
    'kitty.cc',
  ],
  'include_dirs': [
    'headers',
  ],
  'link_settings': {
    'libraries': [
      '-lm',
    ],
    'library_dirs': [
      '/usr/lib',
    ],
  },
  'test': 0,
}
```

Merged dictionary:

```
{
  'target_name': 'hello',
  'sources': [
    'kitty.cc',
  ],
  'include_dirs': [
    'shared_stuff/public',  # Merged, list item prepended due to include_dirs+
    'headers',
  ],
  'link_settings': {
    'libraries': [
      '-lm',
      '-lshared_stuff',  # Merged, list item appended
    ],
    'library_dirs': [
      '/usr/lib',
    ],
  },
  'test': 1,  # Merged, int value replaced
}
```

## Pathname Relativization

In a `.gyp` or `.gypi` file, many string values are treated as pathnames
relative to the file in which they are defined.

String values associated with the following keys, or contained within
lists associated with the following keys, are treated as pathnames:

  * destination
  * files
  * include\_dirs
  * inputs
  * libraries
  * outputs
  * sources
  * mac\_bundle\_resources
  * mac\_framework\_dirs
  * msvs\_cygwin\_dirs
  * msvs\_props

Additionally, string values associated with keys ending in the following
suffixes, or contained within lists associated with keys ending in the
following suffixes, are treated as pathnames:

  * `_dir`
  * `_dirs`
  * `_file`
  * `_files`
  * `_path`
  * `_paths`

However, any string value beginning with any of these characters is
excluded from pathname relativization:

  * `/` for identifying absolute paths.
  * `$` for introducing build system variable expansions.
  * `-` to support specifying such items as `-llib`, meaning “library
    `lib` in the library search path.”
  * `<`, `>`, and `!` for GYP expansions.

When merging such relative pathnames, they are adjusted so that they can
remain valid relative pathnames, despite being relative to a new home.

#### Example

Source dictionary from `../build/common.gypi`:

```
{
  'include_dirs': ['include'],  # Treated as relative to ../build
  'libraries': ['-lz'],  # Not treated as a pathname, begins with a dash
  'defines': ['NDEBUG'],  # defines does not contain pathnames
}
```

Target dictionary, from `base.gyp`:

```
{
  'sources': ['string_util.cc'],
}
```

Merged dictionary:

```
{
  'sources': ['string_util.cc'],
  'include_dirs': ['../build/include'],
  'libraries': ['-lz'],
  'defines': ['NDEBUG'],
}
```

Because of pathname relativization, after the merge is complete, all of
the pathnames in the merged dictionary are valid relative to the
directory containing `base.gyp`.

## List Singletons

Some list items are treated as singletons, and the list merge process
will enforce special rules when merging them.  At present, any string
item in a list that does not begin with a dash (`-`) is treated as a
singleton, although **this is subject to change.**  When appending or
prepending a singleton to a list, if the item is already in the list,
only the earlier instance is retained in the merged list.

#### Example

Source dictionary:

```
{
  'defines': [
    'EXPERIMENT=1',
    'NDEBUG',
  ],
}
```

Destination dictionary:

```
{
  'defines': [
    'NDEBUG',
    'USE_THREADS',
  ],
}
```

Merged dictionary:

```
{
  'defines': [
    'NDEBUG',
    'USE_THREADS',
    'EXPERIMENT=1',  # Note that NDEBUG is not appended after this.
  ],
}
```

## Including Other Files

If the `-I` (`--include`) argument was used to invoke GYP, any files
specified will be implicitly merged into the root dictionary of all
`.gyp` files.

An [includes](#includes) section may be placed anywhere within a
`.gyp` or `.gypi` (include) file.  `includes` sections contain lists of
other files to include.  They are processed sequentially and merged into
the enclosing dictionary at the point that the `includes` section was
found.  `includes` sections at the root of a `.gyp` file dictionary are
merged after any `-I` includes from the command line.

[includes](#includes) sections are processed immediately after a file is
loaded, even before [variable and conditional
processing](#Variables_and_Conditionals), so it is not possible to
include a file based on a [variable reference](#Variable_Expansions).
While it would be useful to be able to include files based on variable
expansions, it is most likely more useful to allow included files access
to variables set by the files that included them.

An [includes](#includes) section may, however, be placed within a
[conditional](#Conditionals) section.  The included file itself will
be loaded unconditionally, but its dictionary will be discarded if the
associated condition is not true.

## Variables and Conditionals

### Variables

There are three main types of variables within GYP.

  * Predefined variables.  By convention, these are named with
    `CAPITAL_LETTERS`.  Predefined variables are set automatically by
    GYP.  They may be overridden, but it is not advisable to do so.  See
    [Predefined Variables](#Predefined_Variables) for a list of
    variables that GYP provides.
  * User-defined variables.  Within any dictionary, a key named
    `variables` can be provided, containing a mapping between variable
    names (keys) and their contents (values), which may be strings,
    integers, or lists of strings.  By convention, user-defined
    variables are named with `lowercase_letters`.
  * Automatic variables.  Within any dictionary, any key with a string
    value has a corresponding automatic variable whose name is the same
    as the key name with an underscore (`_`) prefixed.  For example, if
    your dictionary contains `type: 'static_library'`, an automatic
    variable named `_type` will be provided, and its value will be a
    string, `'static_library'`.

Variables are inherited from enclosing scopes.

### Providing Default Values for Variables (%)

Within a `variables` section, keys named with percent sign (`%`)
suffixes mean that the variable should be set only if it is undefined at
the time it is processed.  This can be used to provide defaults for
variables that would otherwise be undefined, so that they may reliably
be used in [variable expansion or conditional
processing](#Variables_and_Conditionals).

### Predefined Variables

Each GYP generator module provides defaults for the following variables:

  * `OS`: The name of the operating system that the generator produces
    output for.  Common values for values for `OS` are:

    * `'linux'`
    * `'mac'`
    * `'win'`

    But other values may be encountered and this list should not be
    considered exhaustive.  The `gypd` (debug) generator module does not
    provide a predefined value for `OS`.  When invoking GYP with the
    `gypd` module, if a value for `OS` is needed, it must be provided on
    the command line, such as `gyp -f gypd -DOS=mac`.

    GYP generators also provide defaults for these variables.  They may
    be expressed in terms of variables used by the build system that
    they generate for, often in `$(VARIABLE)` format.  For example, the
    GYP `PRODUCT_DIR` variable maps to the Xcode `BUILT_PRODUCTS_DIR`
    variable, so `PRODUCT_DIR` is defined by the Xcode generator as
    `$(BUILT_PRODUCTS_DIR)`.
  * `EXECUTABLE_PREFIX`: A prefix, if any, applied to executable names.
    Usually this will be an empty string.
  * `EXECUTABLE_SUFFIX`: A suffix, if any, applied to executable names.
    On Windows, this will be `.exe`, elsewhere, it will usually be an
    empty string.
  * `INTERMEDIATE_DIR`: A directory that can be used to place
    intermediate build results in.  `INTERMEDIATE_DIR` is only
    guaranteed to be accessible within a single target (See targets).
    This variable is most useful within the context of rules and actions
    (See rules, See actions).  Compare with `SHARED_INTERMEDIATE_DIR`.
  * `PRODUCT_DIR`: The directory in which the primary output of each
    target, such as executables and libraries, is placed.
  * `RULE_INPUT_ROOT`: The base name for the input file (e.g. "`foo`").
    See Rules.
  * `RULE_INPUT_EXT`: The file extension for the input file (e.g.
    "`.cc`").  See Rules.
  * `RULE_INPUT_NAME`: Full name of the input file (e.g. "`foo.cc`").
    See Rules.
  * `RULE_INPUT_PATH`: Full path to the input file (e.g.
    "`/bar/foo.cc`").  See Rules.
  * `SHARED_INTERMEDIATE_DIR`: A directory that can be used to place
    intermediate build results in, and have them be accessible to other
    targets.  Unlike `INTERMEDIATE_DIR`, each target in a project,
    possibly spanning multiple `.gyp` files, shares the same
    `SHARED_INTERMEDIATE_DIR`.

The following additional predefined variables may be available under
certain circumstances:

  * `DEPTH`.  When GYP is invoked with a `--depth` argument, when
    processing any `.gyp` file, `DEPTH` will be a relative path from the
    `.gyp` file to the directory specified by the `--depth` argument.

### User-Defined Variables

A user-defined variable may be defined in terms of other variables, but
not other variables that have definitions provided in the same scope.

### Variable Expansions (<, >, <@, >@)

GYP provides two forms of variable expansions, “early” or “pre”
expansions, and “late,” “post,” or “target” expansions.  They have
similar syntax, differing only in the character used to introduce them.

  * Early expansions are introduced by a less-than (`<`) character.
    _Mnemonic: the arrow points to the left, earlier on a timeline._
  * Late expansions are introduced by a less-than (`>`) character.
    _Mnemonic: the arrow points to the right, later on a timeline._

The difference the two phases of expansion is described in [Early and
Late Phases](#Early_and_Late_Phases).

These characters were chosen based upon the requirement that they not
conflict with the variable format used natively by build systems.  While
the dollar sign (`$`) is the most natural fit for variable expansions,
its use was ruled out because most build systems already use that
character for their own variable expansions.  Using different characters
means that no escaping mechanism was needed to differentiate between GYP
variables and build system variables, and writing build system variables
into GYP files is not cumbersome.

Variables may contain lists or strings, and variable expansions may
occur in list or string context.  There are variant forms of variable
expansions that may be used to determine how each type of variable is to
be expanded in each context.

  * When a variable is referenced by `<(VAR)` or `>(VAR)`:
    * If `VAR` is a string, the variable reference within the string is
      replaced by variable's string value.
    * If `VAR` is a list, the variable reference within the string is
      replaced by a string containing the concatenation of all of the
      variable’s list items.  Generally, the items are joined with
      spaces between each, but the specific behavior is
      generator-specific.  The precise encoding used by any generator
      should be one that would allow each list item to be treated as a
      separate argument when used as program arguments on the system
      that the generator produces output for.
  * When a variable is referenced by `<@(VAR)` or `>@(VAR)`:
    * The expansion must occur in list context.
    * The list item must be `'<@(VAR)'` or `'>@(VAR)'` exactly.
    * If `VAR` is a list, each of its elements are inserted into the
      list in which expansion is taking place, replacing the list item
      containing the variable reference.
    * If `VAR` is a string, the string is converted to a list which is
      inserted into the list in which expansion is taking place as
      above.  The conversion into a list is generator-specific, but
      generally, spaces in the string are taken as separators between
      list items.  The specific method of converting the string to a
      list should be the inverse of the encoding method used to expand
      list variables in string context, above.

GYP treats references to undefined variables as errors.

### Command Expansions (<!, <!@)

Command expansions function similarly to variable expansions, but
instead of resolving variable references, they cause GYP to execute a
command at generation time and use the command’s output as the
replacement.  Command expansions are introduced by a less than and
exclamation mark (`<!`).

In a command expansion, the entire string contained within the
parentheses is passed to the system’s shell.  The command’s output is
assigned to a string value that may subsequently be expanded in list
context in the same way as variable expansions if an `@` character is
used.

In addition, command expansions (unlike other variable expansions) may
include nested variable expansions.  So something like this is allowed:

```
'variables' : [
  'foo': '<!(echo Build Date <!(date))',
],
```

expands to:

```
'variables' : [
  'foo': 'Build Date 02:10:38 PM Fri Jul 24, 2009 -0700 PDT',
],
```

You may also put commands into arrays in order to quote arguments (but
note that you need to use a different string quoting character):

```
'variables' : [
  'files': '<!(["ls", "-1", "Filename With Spaces"])',
],
```

GYP treats command failures (as indicated by a nonzero exit status)
during command expansion as errors.

#### Example

```
{
  'sources': [
    '!(echo filename with space.cc)',
  ],
  'libraries': [
    '!@(pkg-config --libs-only-l apr-1)',
  ],
}
```

might expand to:

```
{
  'sources': [
    'filename with space.cc',  # no @, expands into a single string
  ],
  'libraries': [  # @ was used, so there's a separate list item for each lib
    '-lapr-1',
    '-lpthread',
  ],
}
```

## Conditionals

Conditionals use the same set of variables used for variable expansion.
As with variable expansion, there are two phases of conditional
evaluation:

  * “Early” or “pre” conditional evaluation, introduced in
    [conditions](#conditions) sections.
  * “Late,” “post,” or “target” conditional evaluation, introduced in
    [target\_conditions](#target_conditions) sections.

The syntax for each type is identical, they differ only in the key name
used to identify them and the timing of their evaluation.  A more
complete description of syntax and use is provided in
[conditions](#conditions).

The difference the two phases of evaluation is described in [Early and
Late Phases](#Early_and_Late_Phases).

## Timing of Variable Expansion and Conditional Evaluation

### Early and Late Phases

GYP performs two phases of variable expansion and conditional evaluation:

  * The “early” or “pre” phase operates on [conditions](#conditions)
    sections and the `<` form of [variable
    expansions](#Variable_Expansions).
  * The “late,” “post,” or “target” phase operates on
    [target\_conditions](#target_conditions) sections, the `>` form
    of [variable expansions](#Variable_Expansions),
    and on the `!` form of [command
    expansions](#Command_Expansions_(!,_!@)).

These two phases are provided because there are some circumstances in
which each is desirable.

The “early” phase is appropriate for most expansions and evaluations.
“Early” expansions and evaluations may be performed anywhere within any
`.gyp` or `.gypi` file.

The “late” phase is appropriate when expansion or evaluation must be
deferred until a specific section has been merged into target context.
“Late” expansions and evaluations only occur within `targets` sections
and their descendants.  The typical use case for a late-phase expansion
is to provide, in some globally-included `.gypi` file, distinct
behaviors depending on the specifics of a target.

#### Example

Given this input:

```
{
  'target_defaults': {
    'target_conditions': [
      ['_type=="shared_library"', {'cflags': ['-fPIC']}],
    ],
  },
  'targets': [
    {
      'target_name': 'sharing_is_caring',
      'type': 'shared_library',
    },
    {
      'target_name': 'static_in_the_attic',
      'type': 'static_library',
    },
  ]
}
```

The conditional needs to be evaluated only in target context; it is
nonsense outside of target context because no `_type` variable is
defined.  [target\_conditions](#target_conditions) allows evaluation
to be deferred until after the [targets](#targets) sections are
merged into their copies of [target\_defaults](#target_defaults).
The resulting targets, after “late” phase processing:

```
{
  'targets': [
    {
      'target_name': 'sharing_is_caring',
      'type': 'shared_library',
      'cflags': ['-fPIC'],
    },
    {
      'target_name': 'static_in_the_attic',
      'type': 'static_library',
    },
  ]
}
```

### Expansion and Evaluation Performed Simultaneously

During any expansion and evaluation phase, both expansion and evaluation
are performed simultaneously.  The process for handling variable
expansions and conditional evaluation within a dictionary is:

  * Load [automatic variables](#Variables) (those with leading
    underscores).
  * If a [variables](#variables) section is present, recurse into its
    dictionary.  This allows [conditionals](#Conditionals) to be
    present within the `variables` dictionary.
  * Load [Variables user-defined variables](#User-Defined) from the
    [variables](#variables) section.
  * For each string value in the dictionary, perform [variable
    expansion](#Variable_Expansions) and, if operating
    during the “late” phase, [command
    expansions](#Command_Expansions).
  * Reload [automatic variables](#Variables) and [Variables
    user-defined variables](#User-Defined) because the variable
    expansion step may have resulted in changes to the automatic
    variables.
  * If a [conditions](#conditions) or
    [target\_conditions](#target_conditions) section (depending on
    phase) is present, recurse into its dictionary.  This is done after
    variable expansion so that conditionals may take advantage of
    expanded automatic variables.
  * Evaluate [conditionals](#Conditionals).
  * Reload [automatic variables](#Variables) and [Variables
    user-defined variables](#User-Defined) because the conditional
    evaluation step may have resulted in changes to the automatic
    variables.
  * Recurse into child dictionaries or lists that have not yet been
    processed.

One quirk of this ordering is that you cannot expect a
[variables](#variables) section within a dictionary’s
[conditional](#Conditionals) to be effective in the dictionary
itself, but the added variables will be effective in any child
dictionaries or lists.  It is thought to be far more worthwhile to
provide resolved [automatic variables](#Variables) to
[conditional](#Conditionals) sections, though.  As a workaround, to
conditionalize variable values, place a [conditions](#conditions) or
[target\_conditions](#target_conditions) section within the
[variables](#variables) section.

## Dependencies and Dependents

In GYP, “dependents” are targets that rely on other targets, called
“dependencies.”  Dependents declare their reliance with a special
section within their target dictionary,
[dependencies](#dependencies).

### Dependent Settings

It is useful for targets to “advertise” settings to their dependents.
For example, a target might require that all of its dependents add
certain directories to their include paths, link against special
libraries, or define certain preprocessor macros.  GYP allows these
cases to be handled gracefully with “dependent settings” sections.
There are three types of such sections:

  * [direct\_dependent\_settings](#direct_dependent_settings), which
    advertises settings to a target's direct dependents only.
  * [all\_dependent\_settings](#all_dependnet_settings), which
    advertises settings to all of a target's dependents, both direct and
    indirect.
  * [link\_settings](#link_settings), which contains settings that
    should be applied when a target’s object files are used as linker
    input.

Furthermore, in some cases, a target needs to pass its dependencies’
settings on to its own dependents.  This might happen when a target’s
own public header files include header files provided by its dependency.
[export\_dependent\_settings](#export_dependent_settings) allows a
target to declare dependencies for which
[direct\_dependent\_settings](#direct_dependent_settings) should be
passed through to its own dependents.

Dependent settings processing merges a copy of the relevant dependent
settings dictionary from a dependency into its relevant dependent
targets.

In most instances,
[direct\_dependent\_settings](#direct_dependent_settings) will be
used.  There are very few cases where
[all\_dependent\_settings](#all_dependent_settings) is actually
correct; in most of the cases where it is tempting to use, it would be
preferable to declare
[export\_dependent\_settings](#export_dependent_settings).  Most
[libraries](#libraries) and [library\_dirs](#library_dirs)
sections should be placed within [link\_settings](#link_settings)
sections.

#### Example

Given:

```
{
  'targets': [
    {
      'target_name': 'cruncher',
      'type': 'static_library',
      'sources': ['cruncher.cc'],
      'direct_dependent_settings': {
        'include_dirs': ['.'],  # dependents need to find cruncher.h.
      },
      'link_settings': {
        'libraries': ['-lm'],  # cruncher.cc does math.
      },
    },
    {
      'target_name': 'cruncher_test',
      'type': 'executable',
      'dependencies': ['cruncher'],
      'sources': ['cruncher_test.cc'],
    },
  ],
}
```

After dependent settings processing, the dictionary for `cruncher_test`
will be:

```
{
  'target_name': 'cruncher_test',
  'type': 'executable',
  'dependencies': ['cruncher'],  # implies linking against cruncher
  'sources': ['cruncher_test.cc'],
  'include_dirs': ['.']
  'libraries': ['-lm'],
},
```

If `cruncher` was declared as a `shared_library` instead of a
`static_library`, the `cruncher_test` target would not contain `-lm`,
but instead, `cruncher` itself would link against `-lm`.

## Linking Dependencies

The precise meaning of a dependency relationship varies with the
[types](#type) of the [targets](#targets) at either end of the
relationship.  In GYP, a dependency relationship can indicate two things
about how targets relate to each other:

  * Whether the dependent target needs to link against the dependency.
  * Whether the dependency target needs to be built prior to the
    dependent.  If the former case is true, this case must be true as
    well.

The analysis of the first item is complicated by the differences between
static and shared libraries.

  * Static libraries are simply collections of object files (`.o` or
    `.obj`) that are used as inputs to a linker (`ld` or `link.exe`).
    Static libraries don't link against other libraries, they’re
    collected together and used when eventually linking a shared library
    or executable.
  * Shared libraries are linker output and must undergo symbol
    resolution.  They must link against other libraries (static or
    shared) in order to facilitate symbol resolution.  They may be used
    as libraries in subsequent link steps.
  * Executables are also linker output, and also undergo symbol
    resolution.  Like shared libraries, they must link against static
    and shared libraries to facilitate symbol resolution.  They may not
    be reused as linker inputs in subsequent link steps.

Accordingly, GYP performs an operation referred to as “static library
dependency adjustment,” in which it makes each linker output target
(shared libraries and executables) link against the static libraries it
depends on, either directly or indirectly.  Because the linkable targets
link against these static libraries, they are also made direct
dependents of the static libraries.

As part of this process, GYP is also able to remove the direct
dependency relationships between two static library targets, as a
dependent static library does not actually need to link against a
dependency static library.  This removal facilitates speedier builds
under some build systems, as they are now free to build the two targets
in parallel.  The removal of this dependency is incorrect in some cases,
such as when the dependency target contains [rules](#rules) or
[actions](#actions) that generate header files required by the
dependent target.  In such cases, the dependency target, the one
providing the side-effect files, must declare itself as a
[hard\_dependency](#hard_dependency).  This setting instructs GYP to
not remove the dependency link between two static library targets in its
generated output.

## Loading Files to Resolve Dependencies

When GYP runs, it loads all `.gyp` files needed to resolve dependencies
found in [dependencies](#dependencies) sections.  These files are not
merged into the files that reference them, but they may contain special
sections that are merged into dependent target dictionaries.

## Build Configurations

Explain this.

## List Filters

GYP allows list items to be filtered by “exclusions” and “patterns.”
Any list containing string values in a dictionary may have this
filtering applied.  For the purposes of this section, a list modified by
exclusions or patterns is referred to as a “base list”, in contrast to
the “exclusion list” and “pattern list” that operates on it.

  * For a base list identified by key name `key`, the `key!` list
    provides exclusions.
  * For a base list identified by key name `key`, the `key/` list
    provides regular expression pattern-based filtering.

Both `key!` and `key/` may be present.  The `key!` exclusion list will
be processed first, followed by the `key/` pattern list.

Exclusion lists are most powerful when used in conjunction with
[conditionals](#Conditionals).

## Exclusion Lists (!)

An exclusion list provides a way to remove items from the related list
based on exact matching.  Any item found in an exclusion list will be
removed from the corresponding base list.

#### Example

This example excludes files from the `sources` based on the setting of
the `OS` variable.

```
{
  'sources:' [
    'mac_util.mm',
    'win_util.cc',
  ],
  'conditions': [
    ['OS=="mac"', {'sources!': ['win_util.cc']}],
    ['OS=="win"', {'sources!': ['mac_util.cc']}],
  ],
}
```

## Pattern Lists (/)

Pattern lists are similar to, but more powerful than, [exclusion
lists](#Exclusion_Lists_(!)).  Each item in a pattern list is itself
a two-element list.  The first item is a string, either `'include'` or
`'exclude'`, specifying the action to take.  The second item is a string
specifying a regular expression.  Any item in the base list matching the
regular expression pattern will either be included or excluded, based on
the action specified.

Items in a pattern list are processed in sequence, and an excluded item
that is later included will not be removed from the list (unless it is
subsequently excluded again.)

Pattern lists are processed after [exclusion
lists](#Exclusion_Lists_(!)), so it is possible for a pattern list to
re-include items previously excluded by an exclusion list.

Nothing is actually removed from a base list until all items in an
[exclusion list](#Exclusion_Lists_(!)) and pattern list have been
evaluated.  This allows items to retain their correct position relative
to one another even after being excluded and subsequently included.

#### Example

In this example, a uniform naming scheme is adopted for
platform-specific files.

```
{
  'sources': [
    'io_posix.cc',
    'io_win.cc',
    'launcher_mac.cc',
    'main.cc',
    'platform_util_linux.cc',
    'platform_util_mac.mm',
  ],
  'sources/': [
    ['exclude', '_win\\.cc$'],
  ],
  'conditions': [
    ['OS!="linux"', {'sources/': [['exclude', '_linux\\.cc$']]}],
    ['OS!="mac"', {'sources/': [['exclude', '_mac\\.cc|mm?$']]}],
    ['OS=="win"', {'sources/': [
      ['include', '_win\\.cc$'],
      ['exclude', '_posix\\.cc$'],
    ]}],
  ],
}
```

After the pattern list is applied, `sources` will have the following
values, depending on the setting of `OS`:

  * When `OS` is `linux`: `['io_posix.cc', 'main.cc',
    'platform_util_linux.cc']`
  * When `OS` is `mac`: `['io_posix.cc', 'launcher_mac.cc', 'main.cc',
    'platform_util_mac.mm']`
  * When `OS` is `win`: `['io_win.cc', 'main.cc',
    'platform_util_win.cc']`

Note that when `OS` is `win`, the `include` for `_win.cc` files is
processed after the `exclude` matching the same pattern, because the
`sources/` list participates in [merging](#Merging) during
[conditional evaluation](#Conditonals) just like any other list
would.  This guarantees that the `_win.cc` files, previously
unconditionally excluded, will be re-included when `OS` is `win`.

## Locating Excluded Items

In some cases, a GYP generator needs to access to items that were
excluded by an [exclusion list](#Exclusion_Lists_(!)) or [pattern
list](#Pattern_Lists_(/)).  When GYP excludes items during processing
of either of these list types, it places the results in an `_excluded`
list.  In the example above, when `OS` is `mac`, `sources_excluded`
would be set to `['io_win.cc', 'platform_util_linux.cc']`.  Some GYP
generators use this feature to display excluded files in the project
files they generate for the convenience of users, who may wish to refer
to other implementations.

## Processing Order

GYP uses a defined and predictable order to execute the various steps
performed between loading files and generating output.

  * Load files.
    * Load `.gyp` files.  Merge any [command-line
      includes](#Including_Other_Files) into each `.gyp` file’s root
      dictionary.  As [includes](#Including_Other_Files) are found,
      load them as well and [merge](#Merging) them into the scope in
      which the [includes](#includes) section was found.
    * Perform [“early” or “pre”](#Early_and_Late_Phases) [variable
      expansion and conditional
      evaluation](#Variables_and_Conditionals).
    * [Merge](#Merging) each [target’s](#targets) dictionary into
      the `.gyp` file’s root [target\_defaults](#target_defaults)
      dictionary.
    * Scan each [target](#targets) for
      [dependencies](#dependencies), and repeat the above steps for
      any newly-referenced `.gyp` files not yet loaded.
  * Scan each [target](#targets) for wildcard
    [dependencies](#dependencies), expanding the wildcards.
  * Process [dependent settings](#Dependent_Settings).  These
    sections are processed, in order:
    * [all\_dependent\_settings](#all_dependent_settings)
    * [direct\_dependent\_settings](#direct_dependent_settings)
    * [link\_dependent\_settings](#link_dependent_settings)
  * Perform [static library dependency
    adjustment](#Linking_Dependencies).
  * Perform [“late,” “post,” or “target”](#Early_and_Late_Phases)
    [variable expansion and conditional
    evaluation](#Variables_and_Conditionals) on [target](#targets)
    dictionaries.
  * Merge [target](#targets) settings into
    [configurations](#configurations) as appropriate.
  * Process [exclusion and pattern
    lists](#List_Exclusions_and_Patterns).

## Settings Keys

### Settings that may appear anywhere

#### conditions

_List of `condition` items_

A `conditions` section introduces a subdictionary that is only merged
into the enclosing scope based on the evaluation of a conditional
expression.  Each `condition` within a `conditions` list is itself a
list of at least two items:

  1. A string containing the conditional expression itself.  Conditional
  expressions may take the following forms:
    * For string values, `var=="value"` and `var!="value"` to test
      equality and inequality.  For example, `'OS=="linux"'` is true
      when the `OS` variable is set to `"linux"`.
    * For integer values, `var==value`, `var!=value`, `var<value`,
      `var<=value`, `var>=value`, and `var>value`, to test equality and
      several common forms of inequality.  For example,
      `'chromium_code==0'` is true when the `chromium_code` variable is
      set to `0`.
    * It is an error for a conditional expression to reference any
      undefined variable.
  1. A dictionary containing the subdictionary to be merged into the
  enclosing scope if the conditional expression evaluates to true.

These two items can be followed by any number of similar two items that
will be evaluated if the previous conditional expression does not
evaluate to true.

An additional optional dictionary can be appended to this sequence of
two items.  This optional dictionary will be merged into the enclosing
scope if none of the conditional expressions evaluate to true.

Within a `conditions` section, each item is processed sequentially, so
it is possible to predict the order in which operations will occur.

There is no restriction on nesting `conditions` sections.

`conditions` sections are very similar to `target_conditions` sections.
See target\_conditions.

#### Example

```
{
  'sources': [
    'common.cc',
  ],
  'conditions': [
    ['OS=="mac"', {'sources': ['mac_util.mm']}],
    ['OS=="win"', {'sources': ['win_main.cc']}, {'sources': ['posix_main.cc']}],
    ['OS=="mac"', {'sources': ['mac_impl.mm']},
     'OS=="win"', {'sources': ['win_impl.cc']},
     {'sources': ['default_impl.cc']}
    ],
  ],
}
```

Given this input, the `sources` list will take on different values based
on the `OS` variable.

  * If `OS` is `"mac"`, `sources` will contain `['common.cc',
    'mac_util.mm', 'posix_main.cc', 'mac_impl.mm']`.
  * If `OS` is `"win"`, `sources` will contain `['common.cc',
    'win_main.cc', 'win_impl.cc']`.
  * If `OS` is any other value such as `"linux"`, `sources` will contain
    `['common.cc', 'posix_main.cc', 'default_impl.cc']`.
# Language Specification

## Objective

Create a tool for the Chromium project that generates native Visual Studio,
Xcode and SCons and/or make build files from a platform-independent input
format.  Make the input format as reasonably general as possible without
spending extra time trying to "get everything right," except where not doing so
would likely lead Chromium to an eventual dead end.  When in doubt, do what
Chromium needs and don't worry about generalizing the solution.

## Background

Numerous other projects, both inside and outside Google, have tried to
create a simple, universal cross-platform build representation that
still allows sufficient per-platform flexibility to accommodate
irreconcilable differences.  The fact that no obvious working candidate
exists that meets Chromium's requirements indicates this is probably a
tougher problem than it appears at first glance.  We aim to succeed by
creating a tool that is highly specific to Chromium's specific use case,
not to the general case of design a completely platform-independent tool
for expressing any possible build.

The Mac has the most sophisticated model for application development
through an IDE.  Consequently, we will use the Xcode model as the
starting point (the input file format must handle Chromium's use of
Xcode seamlessly) and adapt the design as necessary for the other
platforms.

## Overview

The overall design has the following characteristics:

  * Input configurations are specified in files with the suffix `.gyp`.
  * Each `.gyp` file specifies how to build the targets for the
    "component" defined by that file.
  * Each `.gyp` file generates one or more output files appropriate to
    the platform:
    * On Mac, a `.gyp` file generates one Xcode .xcodeproj bundle with
      information about how its targets are built.
    * On Windows, a `.gyp` file generates one Visual Studio .sln file,
      and one Visual Studio .vcproj file per target.
    * On Linux, a `.gyp` file generates one SCons file and/or one
      Makefile per target
  * The `.gyp` file syntax is a Python data structure.
  * Use of arbitrary Python in `.gyp` files is forbidden.
    * Use of eval() with restricted globals and locals on `.gyp` file
      contents restricts the input to an evaluated expression, not
      arbitrary Python statements.
    * All input is expected to comply with JSON, with two exceptions:
      the # character (not inside strings) begins a comment that lasts
      until the end of the line, and trailing commas are permitted at
      the end of list and dict contents.
  * Input data is a dictionary of keywords and values.
  * "Invalid" keywords on any given data structure are not illegal,
    they're just ignored.
    * TODO:  providing warnings on use of illegal keywords would help
      users catch typos.  Figure out something nice to do with this.

## Detailed Design

Some up-front design principles/thoughts/TODOs:

  * Re-use keywords consistently.
  * Keywords that allow configuration of a platform-specific concept get
    prefixed appropriately:
    * Examples:  `msvs_disabled_warnings`, `xcode_framework_dirs`
  * The input syntax is declarative and data-driven.
    * This gets enforced by using Python `eval()` (which only evaluates
      an expression) instead of `exec` (which executes arbitrary python)
  * Semantic meanings of specific keyword values get deferred until all
    are read and the configuration is being evaluated to spit out the
    appropriate file(s)
  * Source file lists:
    * Are flat lists.  Any imposed ordering within the `.gyp` file (e.g.
      alphabetically) is purely by convention and for developer
      convenience.  When source files are linked or archived together,
      it is expected that this will occur in the order that files are
      listed in the `.gyp` file.
    * Source file lists contain no mechanism for by-hand folder
      configuration (`Filter` tags in Visual Studio, `Groups` in Xcode)
    * A folder hierarchy is created automatically that mirrors the file
      system

  ],
}
```

### Structural Elements

### Top-level Dictionary

This is the single dictionary in the `.gyp` file that defines the
targets and how they're to be built.

The following keywords are meaningful within the top-level dictionary
definition:

| *Keyword*         | *Description*     |
|:------------------|:------------------|
| `conditions`      | A conditional section that may contain other items that can be present in a top-level dictionary, on a conditional basis.  See the "Conditionals" section below. |
| `includes`        | A list of `.gypi` files to be included in the top-level dictionary. |
| `target_defaults` | A dictionary of default settings to be inherited by all targets in the top-level dictionary.  See the "Settings keywords" section below. |
| `targets`         | A list of target specifications.  See the "targets" below. |
| `variables`       | A dictionary containing variable definitions.  Each key in this dictionary is the name of a variable, and each value must be a string value that the variable is to be set to. |

### targets

A list of dictionaries defining targets to be built by the files
generated from this `.gyp` file.

Targets may contain `includes`, `conditions`, and `variables` sections
as permitted in the root dictionary. The following additional keywords
have structural meaning for target definitions:

| *Keyword*         | *Description*     |
|:---------------------------- |:------------------------------------------|
| `actions`                    | A list of special custom actions to perform on a specific input file, or files, to produce output files.  See the "Actions" section below. |
| `all_dependent_settings`     | A dictionary of settings to be applied to all dependents of the target, transitively.  This includes direct dependents and the entire set of their dependents, and so on.  This section may contain anything found within a `target` dictionary, except `configurations`, `target_name`, and `type` sections.  Compare `direct_dependent_settings` and `link_settings`. |
| `configurations`             | A list of dictionaries defining build configurations for the target.  See the "Configurations" section below.  |
| `copies`                     | A list of copy actions to perform. See the "Copies" section below. |
| `defines`                    | A list of preprocesor definitions to be passed on the command line to the C/C++ compiler (via `-D` or `/D` options). |
| `dependencies`               | A list of targets on which this target depends.  Targets in other `.gyp` files are specified as `../path/to/other.gyp:target_we_want`. |
| `direct_dependent_settings`  | A dictionary of settings to be applied to other targets that depend on this target.  These settings will only be applied to direct dependents.  This section may contain anything found within a `target` dictionary, except `configurations`, `target_name`, and `type` sections.  Compare with `all_dependent_settings` and `link_settings`. |
| `include_dirs`               | A list of include directories to be passed on the command line to the C/C++ compiler (via `-I` or `/I` options). |
| `libraries`                  | A list of list of libraries (and/or frameworks) on which this target depends. |
| `link_settings`              | A dictionary of settings to be applied to targets in which this target's contents are linked.  `executable` and `shared_library` targets are linkable, so if they depend on a non-linkable target such as a `static_library`, they will adopt its `link_settings`.  This section can contain anything found within a `target` dictionary, except `configurations`, `target_name`, and `type` sections.  Compare `all_dependent_settings` and `direct_dependent_settings`. |
| `rules`                      | A special custom action to perform on a list of input files, to produce output files.  See the "Rules" section below. |
| `sources`                    | A list of source files that are used to build this target or which should otherwise show up in the IDE for this target.  In practice, we expect this list to be a union of all files necessary to build the target on all platforms, as well as other related files that aren't actually used for building, like README files. |
| `target_conditions`          | Like `conditions`, but evaluation is delayed until the settings have been merged into an actual target.  `target_conditions` may be used to place conditionals into a `target_defaults` section but have them still depend on specific target settings. |
| `target_name`                | The name of a target being defined. |
| `type`                       | The type of target being defined. This field currently supports `executable`, `static_library`, `shared_library`, and `none`.  The `none` target type is useful when producing output which is not linked. For example, converting raw translation files into resources or documentation into platform specific help files. |
| `msvs_props`                 | A list of Visual Studio property sheets (`.vsprops` files) to be used to build the target. |
| `xcode_config_file`          | An Xcode configuration (`.xcconfig` file) to be used to build the target. |
| `xcode_framework_dirs`       | A list of framework directories be used to build the target. |

You can affect the way that lists/dictionaries are merged together (for
example the way a list in target\_defaults interacts with the same named
list in the target itself) with a couple of special characters, which
are covered in [Merge
Basics](InputFormatReference#Merge_Basics_(=,_?,_+).md) and [List
Filters](InputFormatReference#List_Filters.md) on the
InputFormatReference page.

### configurations

`configurations` sections may be found within `targets` or
`target_defaults` sections.  The `configurations` section is a list of
dictionaries specifying different build configurations.  Because
configurations are implemented as lists, it is not currently possible to
override aspects of configurations that are imported into a target from
a `target_defaults` section.

NOTE: It is extremely important that each target within a project define
the same set of configurations.  This continues to apply even when a
project spans across multiple `.gyp` files.

A configuration dictionary may contain anything that can be found within
a target dictionary, except for `actions`, `all_dependent_settings`,
`configurations`, `dependencies`, `direct_dependent_settings`,
`libraries`, `link_settings`, `sources`, `target_name`, and `type`.

Configuration dictionaries may also contain these elements:

| *Keyword*            | *Description*                                       |
|:---------------------|:----------------------------------------------------|
| `configuration_name` | Required attribute.  The name of the configuration. |

### Conditionals

Conditionals may appear within any dictionary in a `.gyp` file.  There
are two tpes of conditionals, which differ only in the timing of their
processing.  `conditons` sections are processed shortly after loading
`.gyp` files, and `target_conditons` sections are processed after all
dependencies have been computed.

A conditional section is introduced with a `conditions` or
`target_conditions` dictionary keyword, and is composed of a list.  Each
list contains two or three elements.  The first two elements, which are
always required, are the conditional expression to evaluate and a
dictionary containing settings to merge into the dictionary containing
the `conditions` or `target_conditions` section if the expression
evaluates to true.  The third, optional, list element is a dictionary to
merge if the expression evaluates to false.

The `eval()` of the expression string takes place in the context of
global and/or local dictionaries that constructed from the `.gyp` input
data, and overrides the `__builtin__` dictionary, to prevent the
execution of arbitrary Python code.

### Actions

An `actions` section provides a list of custom build actions to perform
on inputs, producing outputs.  The `actions` section is organized as a
list.  Each item in the list is a dictionary having the following form:

| *Keyword*     | *Type* | *Description*                |
|:--------------|:-------|:-----------------------------|
| `action_name` | string | The name of the action.  Depending on how actions are implemented in the various generators, some may desire or require this property to be set to a unique name; others may ignore this property entirely. |
| `inputs`      | list   | A list of pathnames treated as inputs to the custom action. |
| `outputs`     | list   | A list of pathnames that the custom action produces. |
| `action`      | list   | A command line invocation used to produce `outputs` from `inputs`.  For maximum cross-platform compatibility, invocations that require a Python interpreter should be specified with a first element `"python"`.  This will enable generators for environments with specialized Python installations to be able to perform the action in an appropriate Python environment. |
| `message`     | string | A message to be displayed to the user by the build system when the action is run. |

Build environments will compare `inputs` and `outputs`.  If any `output`
is missing or is outdated relative to any `input`, the custom action
will be invoked.  If all `outputs` are present and newer than all
`inputs`, the `outputs` are considered up-to-date and the action need
not be invoked.

Actions are implemented in Xcode as shell script build phases performed
prior to the compilation phase.  In the Visual Studio generator, actions
appear files with a `FileConfiguration` containing a custom
`VCCustomBuildTool` specifying the remainder of the inputs, the outputs,
and the action.

Combined with variable expansions, actions can be quite powerful.  Here
is an example action that leverages variable expansions to minimize
duplication of pathnames:

```
      'sources': [
        # libraries.cc is generated by the js2c action below.
        '<(INTERMEDIATE_DIR)/libraries.cc',
      ],
      'actions': [
        {
          'variables': {
            'core_library_files': [
              'src/runtime.js',
              'src/v8natives.js',
              'src/macros.py',
            ],
          },
          'action_name': 'js2c',
          'inputs': [
            'tools/js2c.py',
            '<@(core_library_files)',
          ],
          'outputs': [
            '<(INTERMEDIATE_DIR)/libraries.cc',
            '<(INTERMEDIATE_DIR)/libraries-empty.cc',
          ],
          'action': ['python', 'tools/js2c.py', '<@(_outputs)', 'CORE', '<@(core_library_files)'],
        },
      ],
```

### Rules

A `rules` section provides custom build action to perform on inputs, producing
outputs.  The `rules` section is organized as a list.  Each item in the list is
a dictionary having the following form:

| *Keyword*   | *Type* | *Description*                            |
|:------------|:-------|:-----------------------------------------|
| `rule_name` | string | The name of the rule.  Depending on how Rules are implemented in the various generators, some may desire or require this property to be set to a unique name; others may ignore this property entirely. |
| `extension` | string | All source files of the current target with the given extension will be treated successively as inputs to the rule. |
| `inputs`    | list   | Additional dependencies of the rule. |
| `outputs`   | list   | A list of pathnames that the rule produces. Has access to `RULE_INPUT_` variables (see below). |
| `action`    | list   | A command line invocation used to produce `outputs` from `inputs`.  For maximum cross-platform compatibility, invocations that require a Python interpreter should be specified with a first element `"python"`.  This will enable generators for environments with specialized Python installations to be able to perform the action in an appropriate Python environment. Has access to `RULE_INPUT_` variables (see below). |
| `message`   | string | A message to be displayed to the user by the build system when the action is run. Has access to `RULE_INPUT_` variables (see below). |

There are several variables available to `outputs`, `action`, and `message`.

|  *Variable*          | *Description*                       |
|:---------------------|:------------------------------------|
| `RULE_INPUT_PATH`    | The full path to the current input. |
| `RULE_INPUT_DIRNAME` | The directory of the current input. |
| `RULE_INPUT_NAME`    | The file name of the current input. |
| `RULE_INPUT_ROOT`    | The file name of the current input without extension. |
| `RULE_INPUT_EXT`     | The file name extension of the current input. |

Rules can be thought of as Action generators. For each source selected
by `extension` an special action is created. This action starts out with
the same `inputs`, `outputs`, `action`, and `message` as the rule. The
source is added to the action's `inputs`. The `outputs`, `action`, and
`message` are then handled the same but with the additional variables.
If the `_output` variable is used in the `action` or `message` the
`RULE_INPUT_` variables in `output` will be expanded for the current
source.

### Copies

A `copies` section provides a simple means of copying files.  The
`copies` section is organized as a list.  Each item in the list is a
dictionary having the following form:

| *Keyword*     | *Type* | *Description*                 |
|:--------------|:-------|:------------------------------|
| `destination` | string | The directory into which the `files` will be copied. |
| `files`       | list   | A list of files to be copied. |

The copies will be created in `destination` and have the same file name
as the file they are copied from. Even if the `files` are from multiple
directories they will all be copied into the `destination` directory.
Each `destination` file has an implicit build dependency on the file it
is copied from.

### Generated Xcode .pbxproj Files

We derive the following things in a `project.pbxproj` plist file within
an `.xcodeproj` bundle from the above input file formats as follows:

  * `Group hierarchy`: This is generated in a fixed format with contents
    derived from the input files. There is no provision for the user to
    specify additional groups or create a custom hierarchy.
    * `Configuration group`: This will be used with the
      `xcode_config_file` property above, if needed.
    * `Source group`: The union of the `sources` lists of all `targets`
      after applying appropriate `conditions`.  The resulting list is
      sorted and put into a group hierarchy that matches the layout of
      the directory tree on disk, with a root of // (the top of the
      hierarchy).
    * `Frameworks group`: Taken directly from `libraries` value for the
      target, after applying appropriate conditions.
    * `Projects group`: References to other `.xcodeproj` bundles that
      are needed by the `.xcodeproj` in which the group is contained.
    * `Products group`: Output from the various targets.
  * `Project References`:
  * `Project Configurations`:
    * Per-`.xcodeproj` file settings are not supported, all settings are
      applied at the target level.
  * `Targets`:
    * `Phases`: Copy sources, link with libraries/frameworks, ...
    * `Target Configurations`: Specified by input.
    * `Dependencies`: (local and remote)

### Generated Visual Studio .vcproj Files

We derive the following sections in a `.vcproj` file from the above
input file formats as follows:

  * `VisualStudioProject`:
    * `Platforms`:
    * `ToolFiles`:
    * `Configurations`:
      * `Configuration`:
    * `References`:
    * `Files`:
      * `Filter`:
      * `File`:
        * `FileConfiguration`:
          * `Tool`:
    * `Globals`:

### Generated Visual Studio .sln Files

We derive the following sections in a `.sln` file from the above input
file formats as follows:

  * `Projects`:
    * `WebsiteProperties`:
    * `ProjectDependencies`:
  * `Global`:
    * `SolutionConfigurationPlatforms`:
    * `ProjectConfigurationPlatforms`:
    * `SolutionProperties`:
    * `NestedProjects`:

## Caveats

Notes/Question from very first prototype draft of the language.
Make sure these issues are addressed somewhere before deleting.

  * Libraries are easy, application abstraction is harder
    * Applications involves resource compilation
    * Applications involve many inputs
    * Applications include transitive closure of dependencies
  * Specific use cases like cc\_library
    * Mac compiles more than just .c/.cpp files (specifically, .m and .mm
      files)
    * Compiler options vary by:
      * File type
      * Target type
      * Individual file
    * Files may have custom settings per file per platform, but we probably
      don't care or need to support this in gyp.
  * Will all linked non-Chromium projects always use the same versions of every
    subsystem?
  * Variants are difficult.  We've identified the following variants (some
    specific to Chromium, some typical of other projects in the same ballpark):
    * Target platform
    * V8 vs. JSC
    * Debug vs. Release
    * Toolchain (VS version, gcc, version)
    * Host platform
    * L10N
    * Vendor
    * Purify / Valgrind
  * Will everyone upgrade VS at once?
  * What does a dylib dependency mean?
# Generate Your Projects (gyp-next)

GYP is a Meta-Build system: a build system that generates other build systems.

* [User documentation](./UserDocumentation.md)
* [Input Format Reference](./InputFormatReference.md)
* [Language specification](./LanguageSpecification.md)
* [Hacking](./Hacking.md)
* [Testing](./Testing.md)
* [GYP vs. CMake](./GypVsCMake.md)

GYP is intended to support large projects that need to be built on multiple
platforms (e.g., Mac, Windows, Linux), and where it is important that
the project can be built using the IDEs that are popular on each platform
as if the project is a "native" one.

It can be used to generate XCode projects, Visual Studio projects, Ninja
build files, and Makefiles. In each case GYP's goal is to replicate as
closely as possible the way one would set up a native build of the project
using the IDE.

GYP can also be used to generate "hybrid" projects that provide the IDE
scaffolding for a nice user experience but call out to Ninja to do the actual
building (which is usually much faster than the native build systems of the
IDEs).

# Testing

NOTE: this document is outdated and needs to be updated. Read with your own discretion.

## Introduction

This document describes the GYP testing infrastructure,
as provided by the `TestGyp.py` module.

These tests emphasize testing the _behavior_ of the
various GYP-generated build configurations:
Visual Studio, Xcode, SCons, Make, etc.
The goal is _not_ to test the output of the GYP generators by,
for example, comparing a GYP-generated Makefile
against a set of known "golden" Makefiles
(although the testing infrastructure could
be used to write those kinds of tests).
The idea is that the generated build configuration files
could be completely written to add a feature or fix a bug
so long as they continue to support the functional behaviors
defined by the tests:  building programs, shared libraries, etc.

## "Hello, world!" GYP test configuration

Here is an actual test configuration,
a simple build of a C program to print `"Hello, world!"`.

```
  $ ls -l test/hello
  total 20
  -rw-r--r-- 1 knight knight 312 Jul 30 20:22 gyptest-all.py
  -rw-r--r-- 1 knight knight 307 Jul 30 20:22 gyptest-default.py
  -rwxr-xr-x 1 knight knight 326 Jul 30 20:22 gyptest-target.py
  -rw-r--r-- 1 knight knight  98 Jul 30 20:22 hello.c
  -rw-r--r-- 1 knight knight 142 Jul 30 20:22 hello.gyp
  $
```

The `gyptest-*.py` files are three separate tests (test scripts)
that use this configuration.  The first one, `gyptest-all.py`,
looks like this:

```
  #!/usr/bin/env python

  """
  Verifies simplest-possible build of a "Hello, world!" program
  using an explicit build target of 'all'.
  """

  import TestGyp

  test = TestGyp.TestGyp()

  test.run_gyp('hello.gyp')

  test.build_all('hello.gyp')

  test.run_built_executable('hello', stdout="Hello, world!\n")

  test.pass_test()
```

The test script above runs GYP against the specified input file
(`hello.gyp`) to generate a build configuration.
It then tries to build the `'all'` target
(or its equivalent) using the generated build configuration.
Last, it verifies that the build worked as expected
by running the executable program (`hello`)
that was just presumably built by the generated configuration,
and verifies that the output from the program
matches the expected `stdout` string (`"Hello, world!\n"`).

Which configuration is generated
(i.e., which build tool to test)
is specified when the test is run;
see the next section.

Surrounding the functional parts of the test
described above are the header,
which should be basically the same for each test
(modulo a different description in the docstring):

```
  #!/usr/bin/env python

  """
  Verifies simplest-possible build of a "Hello, world!" program
  using an explicit build target of 'all'.
  """

  import TestGyp

  test = TestGyp.TestGyp()
```

Similarly, the footer should be the same in every test:

```
  test.pass_test()
```

## Running tests

Test scripts are run by the `gyptest.py` script.
You can specify (an) explicit test script(s) to run:

```
  $ python gyptest.py test/hello/gyptest-all.py
  PYTHONPATH=/home/knight/src/gyp/trunk/test/lib
  TESTGYP_FORMAT=scons
  /usr/bin/python test/hello/gyptest-all.py
  PASSED
  $
```

If you specify a directory, all test scripts
(scripts prefixed with `gyptest-`) underneath
the directory will be run:

```
  $ python gyptest.py test/hello
  PYTHONPATH=/home/knight/src/gyp/trunk/test/lib
  TESTGYP_FORMAT=scons
  /usr/bin/python test/hello/gyptest-all.py
  PASSED
  /usr/bin/python test/hello/gyptest-default.py
  PASSED
  /usr/bin/python test/hello/gyptest-target.py
  PASSED
  $
```

Or you can specify the `-a` option to run all scripts
in the tree:

```
  $ python gyptest.py -a
  PYTHONPATH=/home/knight/src/gyp/trunk/test/lib
  TESTGYP_FORMAT=scons
  /usr/bin/python test/configurations/gyptest-configurations.py
  PASSED
  /usr/bin/python test/defines/gyptest-defines.py
  PASSED
      .
      .
      .
      .
  /usr/bin/python test/variables/gyptest-commands.py
  PASSED
  $
```

If any tests fail during the run,
the `gyptest.py` script will report them in a
summary at the end.

## Debugging tests

Tests that create intermediate output do so under the gyp/out/testworkarea
directory. On test completion, intermediate output is cleaned up. To preserve
this output, set the environment variable PRESERVE=1. This can be handy to
inspect intermediate data when debugging a test.

You can also set PRESERVE\_PASS=1, PRESERVE\_FAIL=1 or PRESERVE\_NO\_RESULT=1
to preserve output for tests that fall into one of those categories.

# Specifying the format (build tool) to use

By default, the `gyptest.py` script will generate configurations for
the "primary" supported build tool for the platform you're on:
Visual Studio on Windows,
Xcode on Mac,
and (currently) SCons on Linux.
An alternate format (build tool) may be specified
using the `-f` option:

```
  $ python gyptest.py -f make test/hello/gyptest-all.py
  PYTHONPATH=/home/knight/src/gyp/trunk/test/lib
  TESTGYP_FORMAT=make
  /usr/bin/python test/hello/gyptest-all.py
  PASSED
  $
```

Multiple tools may be specified in a single pass as
a comma-separated list:

```
  $ python gyptest.py -f make,scons test/hello/gyptest-all.py
  PYTHONPATH=/home/knight/src/gyp/trunk/test/lib
  TESTGYP_FORMAT=make
  /usr/bin/python test/hello/gyptest-all.py
  PASSED
  TESTGYP_FORMAT=scons
  /usr/bin/python test/hello/gyptest-all.py
  PASSED
  $
```

## Test script functions and methods

The `TestGyp` class contains a lot of functionality
intended to make it easy to write tests.
This section describes the most useful pieces for GYP testing.

(The `TestGyp` class is actually a subclass of more generic
`TestCommon` and `TestCmd` base classes
that contain even more functionality than is
described here.)

### Initialization

The standard initialization formula is:

```
  import TestGyp
  test = TestGyp.TestGyp()
```

This copies the contents of the directory tree in which
the test script lives to a temporary directory for execution,
and arranges for the temporary directory's removal on exit.

By default, any comparisons of output or file contents
must be exact matches for the test to pass.
If you need to use regular expressions for matches,
a useful alternative initialization is:

```
  import TestGyp
  test = TestGyp.TestGyp(match = TestGyp.match_re,
                         diff = TestGyp.diff_re)`
```

### Running GYP

The canonical invocation is to simply specify the `.gyp` file to be executed:

```
  test.run_gyp('file.gyp')
```

Additional GYP arguments may be specified:

```
  test.run_gyp('file.gyp', arguments=['arg1', 'arg2', ...])
```

To execute GYP from a subdirectory (where, presumably, the specified file
lives):

```
  test.run_gyp('file.gyp', chdir='subdir')
```

### Running the build tool

Running the build tool requires passing in a `.gyp` file, which may be used to
calculate the name of a specific build configuration file (such as a MSVS
solution file corresponding to the `.gyp` file).

There are several different `.build_*()` methods for invoking different types
of builds.

To invoke a build tool with an explicit `all` target (or equivalent):

```
  test.build_all('file.gyp')
```

To invoke a build tool with its default behavior (for example, executing `make`
with no targets specified):

```
  test.build_default('file.gyp')
```

To invoke a build tool with an explicit specified target:

```
  test.build_target('file.gyp', 'target')
```

### Running executables

The most useful method executes a program built by the GYP-generated
configuration:

```
  test.run_built_executable('program')
```

The `.run_built_executable()` method will account for the actual built target
output location for the build tool being tested, as well as tack on any
necessary executable file suffix for the platform (for example `.exe` on
Windows).

`stdout=` and `stderr=` keyword arguments specify expected standard output and
error output, respectively.  Failure to match these (if specified) will cause
the test to fail.  An explicit `None` value will suppress that verification:

```
  test.run_built_executable('program',
                            stdout="expect this output\n",
							stderr=None)
```

Note that the default values are `stdout=None` and `stderr=''` (that is, no
check for standard output, and error output must be empty).

Arbitrary executables (not necessarily those built by GYP) can be executed with
the lower-level `.run()` method:

```
  test.run('program')
```

The program must be in the local directory (that is, the temporary directory
for test execution) or be an absolute path name.

### Fetching command output

```
  test.stdout()
```

Returns the standard output from the most recent executed command (including
`.run_gyp()`, `.build_*()`, or `.run*()` methods).

```
  test.stderr()
```

Returns the error output from the most recent executed command (including
`.run_gyp()`, `.build_*()`, or `.run*()` methods).

### Verifying existence or non-existence of files or directories

```
  test.must_exist('file_or_dir')
```

Verifies that the specified file or directory exists, and fails the test if it
doesn't.

```
  test.must_not_exist('file_or_dir')
```

Verifies that the specified file or directory does not exist, and fails the
test if it does.

### Verifying file contents

```
  test.must_match('file', 'expected content\n')
```

Verifies that the content of the specified file match the expected string, and
fails the test if it does not.  By default, the match must be exact, but
line-by-line regular expressions may be used if the `TestGyp` object was
initialized with `TestGyp.match_re`.

```
  test.must_not_match('file', 'expected content\n')
```

Verifies that the content of the specified file does _not_ match the expected
string, and fails the test if it does.  By default, the match must be exact,
but line-by-line regular expressions may be used if the `TestGyp` object was
initialized with `TestGyp.match_re`.

```
  test.must_contain('file', 'substring')
```

Verifies that the specified file contains the specified substring, and fails
the test if it does not.

```
  test.must_not_contain('file', 'substring')
```

Verifies that the specified file does not contain the specified substring, and
fails the test if it does.

```
  test.must_contain_all_lines(output, lines)
```

Verifies that the output string contains all of the "lines" in the specified
list of lines.  In practice, the lines can be any substring and need not be
`\n`-terminaed lines per se.  If any line is missing, the test fails.

```
  test.must_not_contain_any_lines(output, lines)
```

Verifies that the output string does _not_ contain any of the "lines" in the
specified list of lines.  In practice, the lines can be any substring and need
not be `\n`-terminaed lines per se.  If any line exists in the output string,
the test fails.

```
  test.must_contain_any_line(output, lines)
```

Verifies that the output string contains at least one of the "lines" in the
specified list of lines.  In practice, the lines can be any substring and need
not be `\n`-terminaed lines per se.  If none of the specified lines is present,
the test fails.

### Reading file contents

```
  test.read('file')
```

Returns the contents of the specified file.  Directory elements contained in a
list will be joined:

```
  test.read(['subdir', 'file'])
```

### Test success or failure

```
  test.fail_test()
```

Fails the test, reporting `FAILED` on standard output and exiting with an exit
status of `1`.

```
  test.pass_test()
```

Passes the test, reporting `PASSED` on standard output and exiting with an exit
status of `0`.

```
  test.no_result()
```

Indicates the test had no valid result (i.e., the conditions could not be
tested because of an external factor like a full file system).  Reports `NO
RESULT` on standard output and exits with a status of `2`.
# User Documentation

## Introduction

This document is intended to provide a user-level guide to GYP.  The
emphasis here is on how to use GYP to accomplish specific tasks, not on
the complete technical language specification.  (For that, see the
[LanguageSpecification](LanguageSpecification.md).)

The document below starts with some overviews to provide context: an
overview of the structure of a `.gyp` file itself, an overview of a
typical executable-program target in a `.gyp` file, an an overview of a
typical library target in a `.gyp` file.

After the overviews, there are examples of `gyp` patterns for different
common use cases.

## Skeleton of a typical Chromium .gyp file

Here is the skeleton of a typical `.gyp` file in the Chromium tree:

```
  {
    'variables': {
      .
      .
      .
    },
    'includes': [
      '../build/common.gypi',
    ],
    'target_defaults': {
      .
      .
      .
    },
    'targets': [
      {
        'target_name': 'target_1',
          .
          .
          .
      },
      {
        'target_name': 'target_2',
          .
          .
          .
      },
    ],
    'conditions': [
      ['OS=="linux"', {
        'targets': [
          {
            'target_name': 'linux_target_3',
              .
              .
              .
          },
        ],
      }],
      ['OS=="win"', {
        'targets': [
          {
            'target_name': 'windows_target_4',
              .
              .
              .
          },
        ],
      }, { # OS != "win"
        'targets': [
          {
            'target_name': 'non_windows_target_5',
              .
              .
              .
          },
      }],
    ],
  }
```

The entire file just contains a Python dictionary.  (It's actually JSON,
with two small Pythonic deviations: comments are introduced with `#`,
and a `,` (comma)) is legal after the last element in a list or
dictionary.)

The top-level pieces in the `.gyp` file are as follows:

`'variables'`:  Definitions of variables that can be interpolated and
used in various other parts of the file.

`'includes'`:  A list of of other files that will be included in this
file.  By convention, included files have the suffix `.gypi` (gyp
include).

`'target_defaults'`:  Settings that will apply to _all_ of the targets
defined in this `.gyp` file.

`'targets'`:  The list of targets for which this `.gyp` file can
generate builds.  Each target is a dictionary that contains settings
describing all the information necessary to build the target.

`'conditions'`:  A list of condition specifications that can modify the
contents of the items in the global dictionary defined by this `.gyp`
file based on the values of different variablwes.  As implied by the
above example, the most common use of a `conditions` section in the
top-level dictionary is to add platform-specific targets to the
`targets` list.

## Skeleton of a typical executable target in a .gyp file

The most straightforward target is probably a simple executable program.
Here is an example `executable` target that demonstrates the features
that should cover most simple uses of gyp:

```
  {
    'targets': [
      {
        'target_name': 'foo',
        'type': 'executable',
        'msvs_guid': '5ECEC9E5-8F23-47B6-93E0-C3B328B3BE65',
        'dependencies': [
          'xyzzy',
          '../bar/bar.gyp:bar',
        ],
        'defines': [
          'DEFINE_FOO',
          'DEFINE_A_VALUE=value',
        ],
        'include_dirs': [
          '..',
        ],
        'sources': [
          'file1.cc',
          'file2.cc',
        ],
        'conditions': [
          ['OS=="linux"', {
            'defines': [
              'LINUX_DEFINE',
            ],
            'include_dirs': [
              'include/linux',
            ],
          }],
          ['OS=="win"', {
            'defines': [
              'WINDOWS_SPECIFIC_DEFINE',
            ],
          }, { # OS != "win",
            'defines': [
              'NON_WINDOWS_DEFINE',
            ],
          }]
        ],
      },
    ],
  }
```

The top-level settings in the target include:

`'target_name'`: The name by which the target should be known, which
should be unique across all `.gyp` files.  This name will be used as the
project name in the generated Visual Studio solution, as the target name
in the generated XCode configuration, and as the alias for building this
target from the command line of the generated SCons configuration.

`'type'`: Set to `executable`, logically enough.

`'msvs_guid'`: THIS IS ONLY TRANSITIONAL.  This is a hard-coded GUID
values that will be used in the generated Visual Studio solution
file(s).  This allows us to check in a `chrome.sln` file that
interoperates with gyp-generated project files.  Once everything in
Chromium is being generated by gyp, it will no longer be important that
the GUIDs stay constant across invocations, and we'll likely get rid of
these settings,

`'dependencies'`: This lists other targets that this target depends on.
The gyp-generated files will guarantee that the other targets are built
before this target.  Any library targets in the `dependencies` list will
be linked with this target.  The various settings (`defines`,
`include_dirs`, etc.) listed in the `direct_dependent_settings` sections
of the targets in this list will be applied to how _this_ target is
built and linked.  See the more complete discussion of
`direct_dependent_settings`, below.

`'defines'`: The C preprocessor definitions that will be passed in on
compilation command lines (using `-D` or `/D` options).

`'include_dirs'`: The directories in which included header files live.
These will be passed in on compilation command lines (using `-I` or `/I`
options).

`'sources'`: The source files for this target.

`'conditions'`: A block of conditions that will be evaluated to update
the different settings in the target dictionary.

## Skeleton of a typical library target in a .gyp file

The vast majority of targets are libraries.  Here is an example of a
library target including the additional features that should cover most
needs of libraries:

```
  {
    'targets': [
      {
        'target_name': 'foo',
        'type': '<(library)'
        'msvs_guid': '5ECEC9E5-8F23-47B6-93E0-C3B328B3BE65',
        'dependencies': [
          'xyzzy',
          '../bar/bar.gyp:bar',
        ],
        'defines': [
          'DEFINE_FOO',
          'DEFINE_A_VALUE=value',
        ],
        'include_dirs': [
          '..',
        ],
        'direct_dependent_settings': {
          'defines': [
            'DEFINE_FOO',
            'DEFINE_ADDITIONAL',
          ],
          'linkflags': [
          ],
        },
        'export_dependent_settings': [
          '../bar/bar.gyp:bar',
        ],
        'sources': [
          'file1.cc',
          'file2.cc',
        ],
        'conditions': [
          ['OS=="linux"', {
            'defines': [
              'LINUX_DEFINE',
            ],
            'include_dirs': [
              'include/linux',
            ],
          ],
          ['OS=="win"', {
            'defines': [
              'WINDOWS_SPECIFIC_DEFINE',
            ],
          }, { # OS != "win",
            'defines': [
              'NON_WINDOWS_DEFINE',
            ],
          }]
        ],
    ],
  }
```

The possible entries in a library target are largely the same as those
that can be specified for an executable target (`defines`,
`include_dirs`, etc.).  The differences include:

`'type'`: This should almost always be set to '<(library)', which allows
the user to define at gyp time whether libraries are to be built static
or shared.  (On Linux, at least, linking with shared libraries saves
significant link time.) If it's necessary to pin down the type of
library to be built, the `type` can be set explicitly to
`static_library` or `shared_library`.

`'direct_dependent_settings'`: This defines the settings that will be
applied to other targets that _directly depend_ on this target--that is,
that list _this_ target in their `'dependencies'` setting.  This is
where you list the `defines`, `include_dirs`, `cflags` and `linkflags`
that other targets that compile or link against this target need to
build consistently.

`'export_dependent_settings'`: This lists the targets whose
`direct_dependent_settings` should be "passed on" to other targets that
use (depend on) this target.  `TODO:  expand on this description.`

## Use Cases

These use cases are intended to cover the most common actions performed
by developers using GYP.

Note that these examples are _not_ fully-functioning, self-contained
examples (or else they'd be way too long).  Each example mostly contains
just the keywords and settings relevant to the example, with perhaps a
few extra keywords for context.  The intent is to try to show the
specific pieces you need to pay attention to when doing something.
[NOTE:  if practical use shows that these examples are confusing without
additional context, please add what's necessary to clarify things.]

### Add new source files

There are similar but slightly different patterns for adding a
platform-independent source file vs. adding a source file that only
builds on some of the supported platforms.

#### Add a source file that builds on all platforms

**Simplest possible case**: You are adding a file(s) that builds on all
platforms.

Just add the file(s) to the `sources` list of the appropriate dictionary
in the `targets` list:

```
  {
    'targets': [
      {
        'target_name': 'my_target',
        'type': 'executable',
        'sources': [
          '../other/file_1.cc',
          'new_file.cc',
          'subdir/file3.cc',
        ],
      },
    ],
  },
```

File path names are relative to the directory in which the `.gyp` file lives.

Keep the list sorted alphabetically (unless there's a really, really,
_really_ good reason not to).

#### Add a platform-specific source file

##### Your platform-specific file is named `*_linux.{ext}`, `*_mac.{ext}`, `*_posix.{ext}` or `*_win.{ext}`

The simplest way to add a platform-specific source file, assuming you're
adding a completely new file and get to name it, is to use one of the
following standard suffixes:

  * `_linux`  (e.g. `foo_linux.cc`)
  * `_mac`    (e.g. `foo_mac.cc`)
  * `_posix`  (e.g. `foo_posix.cc`)
  * `_win`    (e.g. `foo_win.cc`)

Simply add the file to the `sources` list of the appropriate dict within
the `targets` list, like you would any other source file.

```
  {
    'targets': [
      {
        'target_name': 'foo',
        'type': 'executable',
        'sources': [
          'independent.cc',
          'specific_win.cc',
        ],
      },
    ],
  },
```

The Chromium `.gyp` files all have appropriate `conditions` entries to
filter out the files that aren't appropriate for the current platform.
In the above example, the `specific_win.cc` file will be removed
automatically from the source-list on non-Windows builds.

##### Your platform-specific file does not use an already-defined pattern

If your platform-specific file does not contain a
`*_{linux,mac,posix,win}` substring (or some other pattern that's
already in the `conditions` for the target), and you can't change the
file name, there are two patterns that can be used.

**Prefererred**:  Add the file to the `sources` list of the appropriate
dictionary within the `targets` list.  Add an appropriate `conditions`
section to exclude the specific files name:

```
  {
    'targets': [
      {
        'target_name': 'foo',
        'type': 'executable',
        'sources': [
          'linux_specific.cc',
        ],
        'conditions': [
          ['OS != "linux"', {
            'sources!': [
              # Linux-only; exclude on other platforms.
              'linux_specific.cc',
            ]
          }[,
        ],
      },
    ],
  },
```

Despite the duplicate listing, the above is generally preferred because
the `sources` list contains a useful global list of all sources on all
platforms with consistent sorting on all platforms.

**Non-preferred**: In some situations, however, it might make sense to
list a platform-specific file only in a `conditions` section that
specifically _includes_ it in the `sources` list:

```
  {
    'targets': [
      {
        'target_name': 'foo',
        'type': 'executable',
        'sources': [],
        ['OS == "linux"', {
          'sources': [
            # Only add to sources list on Linux.
            'linux_specific.cc',
          ]
        }],
      },
    ],
  },
```

The above two examples end up generating equivalent builds, with the
small exception that the `sources` lists will list the files in
different orders.  (The first example defines explicitly where
`linux_specific.cc` appears in the list--perhaps in in the
middle--whereas the second example will always tack it on to the end of
the list.)

**Including or excluding files using patterns**: There are more
complicated ways to construct a `sources` list based on patterns.  See
`TODO` below.

### Add a new executable

An executable program is probably the most straightforward type of
target, since all it typically needs is a list of source files, some
compiler/linker settings (probably varied by platform), and some library
targets on which it depends and which must be used in the final link.

#### Add an executable that builds on all platforms

Add a dictionary defining the new executable target to the `targets`
list in the appropriate `.gyp` file.  Example:

```
  {
    'targets': [
      {
        'target_name': 'new_unit_tests',
        'type': 'executable',
        'defines': [
          'FOO',
        ],
        'include_dirs': [
          '..',
        ],
        'dependencies': [
          'other_target_in_this_file',
          'other_gyp2:target_in_other_gyp2',
        ],
        'sources': [
          'new_additional_source.cc',
          'new_unit_tests.cc',
        ],
      },
    ],
  }
```

#### Add a platform-specific executable

Add a dictionary defining the new executable target to the `targets`
list within an appropriate `conditions` block for the platform.  The
`conditions` block should be a sibling to the top-level `targets` list:

```
  {
    'targets': [
    ],
    'conditions': [
      ['OS=="win"', {
        'targets': [
          {
            'target_name': 'new_unit_tests',
            'type': 'executable',
            'defines': [
              'FOO',
            ],
            'include_dirs': [
              '..',
            ],
            'dependencies': [
              'other_target_in_this_file',
              'other_gyp2:target_in_other_gyp2',
            ],
            'sources': [
              'new_additional_source.cc',
              'new_unit_tests.cc',
            ],
          },
        ],
      }],
    ],
  }
```

### Add settings to a target

There are several different types of settings that can be defined for
any given target.

#### Add new preprocessor definitions (`-D` or `/D` flags)

New preprocessor definitions are added by the `defines` setting:

```
  {
    'targets': [
      {
        'target_name': 'existing_target',
        'defines': [
          'FOO',
          'BAR=some_value',
        ],
      },
    ],
  },
```

These may be specified directly in a target's settings, as in the above
example, or in a `conditions` section.

#### Add a new include directory (`-I` or `/I` flags)

New include directories are added by the `include_dirs` setting:

```
  {
    'targets': [
      {
        'target_name': 'existing_target',
        'include_dirs': [
          '..',
          'include',
        ],
      },
    ],
  },
```

These may be specified directly in a target's settings, as in the above
example, or in a `conditions` section.

#### Add new compiler flags

Specific compiler flags can be added with the `cflags` setting:

```
  {
    'targets': [
      {
        'target_name': 'existing_target',
        'conditions': [
          ['OS=="win"', {
            'cflags': [
              '/WX',
            ],
          }, { # OS != "win"
            'cflags': [
              '-Werror',
            ],
          }],
        ],
      },
    ],
  },
```

Because these flags will be specific to the actual compiler involved,
they will almost always be only set within a `conditions` section.

#### Add new linker flags

Setting linker flags is OS-specific. On linux and most non-mac posix
systems, they can be added with the `ldflags` setting:

```
  {
    'targets': [
      {
        'target_name': 'existing_target',
        'conditions': [
          ['OS=="linux"', {
            'ldflags': [
              '-pthread',
            ],
          }],
        ],
      },
    ],
  },
```

Because these flags will be specific to the actual linker involved,
they will almost always be only set within a `conditions` section.

On OS X, linker settings are set via `xcode_settings`, on Windows via
`msvs_settings`.

#### Exclude settings on a platform

Any given settings keyword (`defines`, `include_dirs`, etc.) has a
corresponding form with a trailing `!` (exclamation point) to remove
values from a setting.  One useful example of this is to remove the
Linux `-Werror` flag from the global settings defined in
`build/common.gypi`:

```
  {
    'targets': [
      {
        'target_name': 'third_party_target',
        'conditions': [
          ['OS=="linux"', {
            'cflags!': [
              '-Werror',
            ],
          }],
        ],
      },
    ],
  },
```

### Cross-compiling

GYP has some (relatively limited) support for cross-compiling.

If the variable `GYP_CROSSCOMPILE` or one of the toolchain-related
variables (like `CC_host` or `CC_target`) is set, GYP will think that
you wish to do a cross-compile.

When cross-compiling, each target can be part of a "host" build, a
"target" build, or both. By default, the target is assumed to be (only)
part of the "target" build. The 'toolsets' property can be set on a
target to change the default.

A target's dependencies are assumed to match the build type (so, if A
depends on B, by default that means that a target build of A depends on
a target build of B). You can explicitly depend on targets across
toolchains by specifying "#host" or "#target" in the dependencies list.
If GYP is not doing a cross-compile, the "#host" and "#target" will be
stripped as needed, so nothing breaks.

### Add a new library

TODO:  write intro

#### Add a library that builds on all platforms

Add the a dictionary defining the new library target to the `targets`
list in the appropriate `.gyp` file.  Example:

```
  {
    'targets': [
      {
        'target_name': 'new_library',
        'type': '<(library)',
        'defines': [
          'FOO',
          'BAR=some_value',
        ],
        'include_dirs': [
          '..',
        ],
        'dependencies': [
          'other_target_in_this_file',
          'other_gyp2:target_in_other_gyp2',
        ],
        'direct_dependent_settings': {
          'include_dirs': '.',
        },
        'export_dependent_settings': [
          'other_target_in_this_file',
        ],
        'sources': [
          'new_additional_source.cc',
          'new_library.cc',
        ],
      },
    ],
  }
```

The use of the `<(library)` variable above should be the default `type`
setting for most library targets, as it allows the developer to choose,
at `gyp` time, whether to build with static or shared libraries.
(Building with shared libraries saves a _lot_ of link time on Linux.)

It may be necessary to build a specific library as a fixed type.  Is so,
the `type` field can be hard-wired appropriately.  For a static library:

```
        'type': 'static_library',
```

For a shared library:

```
        'type': 'shared_library',
```

#### Add a platform-specific library

Add a dictionary defining the new library target to the `targets` list
within a `conditions` block that's a sibling to the top-level `targets`
list:

```
  {
    'targets': [
    ],
    'conditions': [
      ['OS=="win"', {
        'targets': [
          {
            'target_name': 'new_library',
            'type': '<(library)',
            'defines': [
              'FOO',
              'BAR=some_value',
            ],
            'include_dirs': [
              '..',
            ],
            'dependencies': [
              'other_target_in_this_file',
              'other_gyp2:target_in_other_gyp2',
            ],
            'direct_dependent_settings': {
              'include_dirs': '.',
            },
            'export_dependent_settings': [
              'other_target_in_this_file',
            ],
            'sources': [
              'new_additional_source.cc',
              'new_library.cc',
            ],
          },
        ],
      }],
    ],
  }
```

### Dependencies between targets

GYP provides useful primitives for establishing dependencies between
targets, which need to be configured in the following situations.

#### Linking with another library target

```
  {
    'targets': [
      {
        'target_name': 'foo',
        'dependencies': [
          'libbar',
        ],
      },
      {
        'target_name': 'libbar',
        'type': '<(library)',
        'sources': [
        ],
      },
    ],
  }
```

Note that if the library target is in a different `.gyp` file, you have
to specify the path to other `.gyp` file, relative to this `.gyp` file's
directory:

```
  {
    'targets': [
      {
        'target_name': 'foo',
        'dependencies': [
          '../bar/bar.gyp:libbar',
        ],
      },
    ],
  }
```

Adding a library often involves updating multiple `.gyp` files, adding
the target to the approprate `.gyp` file (possibly a newly-added `.gyp`
file), and updating targets in the other `.gyp` files that depend on
(link with) the new library.

#### Compiling with necessary flags for a library target dependency

We need to build a library (often a third-party library) with specific
preprocessor definitions or command-line flags, and need to ensure that
targets that depend on the library build with the same settings.  This
situation is handled by a `direct_dependent_settings` block:

```
  {
    'targets': [
      {
        'target_name': 'foo',
        'type': 'executable',
        'dependencies': [
          'libbar',
        ],
      },
      {
        'target_name': 'libbar',
        'type': '<(library)',
        'defines': [
          'LOCAL_DEFINE_FOR_LIBBAR',
          'DEFINE_TO_USE_LIBBAR',
        ],
        'include_dirs': [
          '..',
          'include/libbar',
        ],
        'direct_dependent_settings': {
          'defines': [
            'DEFINE_TO_USE_LIBBAR',
          ],
          'include_dirs': [
            'include/libbar',
          ],
        },
      },
    ],
  }
```

In the above example, the sources of the `foo` executable will be
compiled with the options `-DDEFINE_TO_USE_LIBBAR -Iinclude/libbar`,
because of those settings' being listed in the
`direct_dependent_settings` block.

Note that these settings will likely need to be replicated in the
settings for the library target itsef, so that the library will build
with the same options.  This does not prevent the target from defining
additional options for its "internal" use when compiling its own source
files.  (In the above example, these are the `LOCAL_DEFINE_FOR_LIBBAR`
define, and the `..` entry in the `include_dirs` list.)

#### When a library depends on an additional library at final link time

```
  {
    'targets': [
      {
        'target_name': 'foo',
        'type': 'executable',
        'dependencies': [
          'libbar',

### Support for Mac OS X bundles

gyp supports building bundles on OS X (.app, .framework, .bundle, etc).
Here is an example of this:

```
    {
      'target_name': 'test_app',
      'product_name': 'Test App Gyp',
      'type': 'executable',
      'mac_bundle': 1,
      'sources': [
        'main.m',
        'TestAppAppDelegate.h',
        'TestAppAppDelegate.m',
      ],
      'mac_bundle_resources': [
        'TestApp/English.lproj/InfoPlist.strings',
        'TestApp/English.lproj/MainMenu.xib',
      ],
      'link_settings': {
        'libraries': [
          '$(SDKROOT)/System/Library/Frameworks/Cocoa.framework',
        ],
      },
      'xcode_settings': {
        'INFOPLIST_FILE': 'TestApp/TestApp-Info.plist',
      },
    },
```

The `mac_bundle` key tells gyp that this target should be a bundle.
`executable` targets get extension `.app` by default, `shared_library`
targets get `.framework` – but you can change the bundle extensions by
setting `product_extension` if you want. Files listed in
`mac_bundle_resources` will be copied to the bundle's `Resource` folder
of the bundle. You can also set
`process_outputs_as_mac_bundle_resources` to 1 in actions and rules to
let the output of actions and rules be added to that folder (similar to
`process_outputs_as_sources`). If `product_name` is not set, the bundle
will be named after `target_name`as usual.

### Move files (refactoring)

TODO

### Custom build steps

TODO

#### Adding an explicit build step to generate specific files

    A VS2008 project with most of the options defined was created through the
    VS2008 IDE.  It was then converted to VS2010.  The tool settings found in
    the .vcproj and .vcxproj files were converted to the two dictionaries
    msvs_settings and expected_msbuild_settings.

    Note that for many settings, the VS2010 converter adds macros like
    %(AdditionalIncludeDirectories) to make sure than inherited values are
    included.  Since the Gyp projects we generate do not use inheritance,
    we removed these macros.  They were:

"""
This script is intended for use as a GYP_GENERATOR. It takes as input (by way of
the generator flag config_path) the path of a json file that dictates the files
and targets to search for. The following keys are supported:
files: list of paths (relative) of the files to search for.
test_targets: unqualified target names to search for. Any target in this list
that depends upon a file in |files| is output regardless of the type of target
or chain of dependencies.
additional_compile_targets: Unqualified targets to search for in addition to
test_targets. Targets in the combined list that depend upon a file in |files|
are not necessarily output. For example, if the target is of type none then the
target is not output (but one of the descendants of the target will be).

The following is output:
error: only supplied if there is an error.
compile_targets: minimal set of targets that directly or indirectly (for
  targets of type none) depend on the files in |files| and is one of the
  supplied targets or a target that one of the supplied targets depends on.
  The expectation is this set of targets is passed into a build step. This list
  always contains the output of test_targets as well.
test_targets: set of targets from the supplied |test_targets| that either
  directly or indirectly depend upon a file in |files|. This list if useful
  if additional processing needs to be done for certain targets after the
  build, such as running tests.
status: outputs one of three values: none of the supplied files were found,
  one of the include files changed so that it should be assumed everything
  changed (in this case test_targets and compile_targets are not output) or at
  least one file was found.
invalid_targets: list of supplied targets that were not found.

Example:
Consider a graph like the following:
  A     D
 / \
B   C
A depends upon both B and C, A is of type none and B and C are executables.
D is an executable, has no dependencies and nothing depends on it.
If |additional_compile_targets| = ["A"], |test_targets| = ["B", "C"] and
files = ["b.cc", "d.cc"] (B depends upon b.cc and D depends upon d.cc), then
the following is output:
|compile_targets| = ["B"] B must built as it depends upon the changed file b.cc
and the supplied target A depends upon it. A is not output as a build_target
as it is of type none with no rules and actions.
|test_targets| = ["B"] B directly depends upon the change file b.cc.

Even though the file d.cc, which D depends upon, has changed D is not output
as it was not supplied by way of |additional_compile_targets| or |test_targets|.

If the generator flag analyzer_output_path is specified, output is written
there. Otherwise output is written to stdout.

In Gyp the "all" target is shorthand for the root targets in the files passed
to gyp. For example, if file "a.gyp" contains targets "a1" and
"a2", and file "b.gyp" contains targets "b1" and "b2" and "a2" has a dependency
on "b2" and gyp is supplied "a.gyp" then "all" consists of "a1" and "a2".
Notice that "b1" and "b2" are not in the "all" target as "b.gyp" was not
directly supplied to gyp. OTOH if both "a.gyp" and "b.gyp" are supplied to gyp
then the "all" target includes "b1" and "b2".

"""cmake output module

This module is under development and should be considered experimental.

This module produces cmake (2.8.8+) input as its output. One CMakeLists.txt is
created for each configuration.

This module's original purpose was to support editing in IDEs like KDevelop
which use CMake for project management. It is also possible to use CMake to
generate projects for other IDEs such as eclipse cdt and code::blocks. QtCreator
will convert the CMakeLists.txt to a code::blocks cbp for the editor to read,
but build using CMake. As a result QtCreator editor is unaware of compiler
defines. The generated CMakeLists.txt can also be used to build on Linux. There
is currently no support for building on platforms other than Linux.

The generated CMakeLists.txt should properly compile all projects. However,
there is a mismatch between gyp and cmake with regard to linking. All attempts
are made to work around this, but CMake sometimes sees -Wl,--start-group as a
library and incorrectly repeats it. As a result the output of this generator
should not be relied on for building.

When using with kdevelop, use version 4.4+. Previous versions of kdevelop will
not be able to find the header file directories described in the generated
CMakeLists.txt file.

  should have had that name. This is more or less what the 'make' generator
  does with aliases. However, one goal of this generator is to create CMake

  friendly.

  Since target name collision is rare, we do the above only when required.

"""GYP backend that generates Eclipse CDT settings files.

This backend DOES NOT generate Eclipse CDT projects. Instead, it generates XML
files that can be imported into an Eclipse CDT project. The XML file contains a
list of include paths and symbols (i.e. defines).

Because a full .cproject definition is not created by this generator, it's not
possible to properly define the include dirs and symbols for each file
individually.  Instead, one set of includes/symbols is generated for the entire
project.  This works fairly well (and is a vast improvement in general), but may
still result in a few indexer issues here and there.

This generator has no automated tests, so expect it to be broken.

"""gypd output module

This module produces gyp input as its output.  Output files are given the
.gypd extension to avoid overwriting the .gyp files that they are generated
from.  Internal references to .gyp files (such as those found in
"dependencies" sections) are not adjusted to point to .gypd files instead;
unlike other paths, which are relative to the .gyp or .gypd file, such paths
are relative to the directory from which gyp was run to create the .gypd file.

This generator module is intended to be a sample and a debugging aid, hence
the "d" for "debug" in .gypd.  It is useful to inspect the results of the
various merges, expansions, and conditional evaluations performed by gyp
and to see a representation of what would be fed to a generator module.

It's not advisable to rename .gypd files produced by this module to .gyp,
because they will have all merges, expansions, and evaluations already
performed and the relevant constructs not present in the output; paths to
dependencies may be wrong; and various sections that do not belong in .gyp
files such as such as "included_files" and "*_excluded" will be present.
Output will also be stripped of comments.  This is not intended to be a
general-purpose gyp pretty-printer; for that, you probably just want to
run "pprint.pprint(eval(open('source.gyp').read()))", which will still strip
comments but won't do all of the other things done to this module's output.

The specific formatting of the output generated by this module is subject
to change.

# All files we produce (both at gyp and at build time) appear in the
# build directory (e.g. out/Debug).
#
# Paths within a given .gyp file are always relative to the directory
# containing the .gyp file.  Call these "gyp paths".  This includes
# sources as well as the starting directory a given gyp rule/action
# expects to be run from.  We call the path from the source root to
# the gyp file the "base directory" within the per-.gyp-file
# NinjaWriter code.
#
# All paths as written into the .ninja files are relative to the build
# directory.  Call these paths "ninja paths".
#
# We translate between these two notions of paths with two helper
# functions:
#
# - GypPathToNinja translates a gyp path (i.e. relative to the .gyp file)
#   into the equivalent ninja path.
#
# - GypPathToUniqueOutput translates a gyp path into a ninja path to write
#   an output file; the result can be namespaced such that it is unique
#   to the input file name as well as the output target name.

        # The following problems with Xcode rules were found.  The numbers are
        # Apple radar IDs.  I hope that these shortcomings are addressed, I really
        # liked having the rules handled directly in Xcode during the period that
        # I was prototyping this.
        #
        # 6588600 Xcode compiles custom script rule outputs too soon, compilation
        #         fails.  This occurs when rule outputs from distinct inputs are
        #         interdependent.  The only workaround is to put rules and their
        #         inputs in a separate target from the one that compiles the rule
        #         outputs.  This requires input file cooperation and it means that
        #         process_outputs_as_sources is unusable.
        # 6584932 Need to declare that custom rule outputs should be excluded from
        #         compilation.  A possible workaround is to lie to Xcode about a
        #         rule's output, giving it a dummy file it doesn't know how to
        #         compile.  The rule action script would need to touch the dummy.
        # 6584839 I need a way to declare additional inputs to a custom rule.
        #         A possible workaround is a shell script phase prior to
        #         compilation that touches a rule's primary input files if any
        #         would-be additional inputs are newer than the output.  Modifying
        #         the source tree - even just modification times - feels dirty.
        # 6564240 Xcode "custom script" build rules always dump all environment
        #         variables.  This is a low-prioroty problem and is not a
        #         show-stopper.

  placed into a "sources_excluded" list in the dict.

  Regular expression (regex) filters are contained in dict keys named with a

  The first filter says to exclude all files ending in _linux.cc, _mac.cc, and
  _win.cc.  The second filter then includes all files ending in _mac.cc that
  are now or were once in the "sources" list.  Items matching an "exclude"
  filter are subject to the same processing as would occur if they were listed
  by name in an exclusion list (ending in "!").  Items matching an "include"
  filter are brought back into the main list if previously excluded by an
  exclusion list or exclusion regex filter.  Subsequent matching "exclude"

  * If GCC_PREFIX_HEADER is present, all compilations in that project get an

  * If GCC_PRECOMPILE_PREFIX_HEADER is present too, then the prefix header is
    instead compiled, and all other compilations in the project get an
    additional |-include path_to_compiled_header| instead.
    + Compiled prefix headers have the extension gch. There is one gch file for
      every language used in the project (c, cc, m, mm), since gch files for
      different languages aren't compatible.
    + gch files themselves are built with the target's normal cflags, but they
      obviously don't get the |-include| flag. Instead, they need a -x flag that
      describes their language.
    + All o files in the target need to depend on the gch file, to make sure
      it's built before any o file is built.

  This class helps with some of these tasks, but it needs help from the build
  system for writing dependencies to the gch files, for writing build commands
  for the gch files, and for figuring out the location of the gch files.

"""Xcode project file generator.

This module is both an Xcode project file generator and a documentation of the
Xcode project file format.  Knowledge of the project file format was gained
based on extensive experience with Xcode, and by making changes to projects in
Xcode.app and observing the resultant changes in the associated project files.

XCODE PROJECT FILES

The generator targets the file format as written by Xcode 3.2 (specifically,
3.2.6), but past experience has taught that the format has not changed
significantly in the past several years, and future versions of Xcode are able
to read older project files.

Xcode project files are "bundled": the project "file" from an end-user's
perspective is actually a directory with an ".xcodeproj" extension.  The
project file from this module's perspective is actually a file inside this
directory, always named "project.pbxproj".  This file contains a complete
description of the project and is all that is needed to use the xcodeproj.
Other files contained in the xcodeproj directory are simply used to store
per-user settings, such as the state of various UI elements in the Xcode
application.

The project.pbxproj file is a property list, stored in a format almost
identical to the NeXTstep property list format.  The file is able to carry
Unicode data, and is encoded in UTF-8.  The root element in the property list
is a dictionary that contains several properties of minimal interest, and two
properties of immense interest.  The most important property is a dictionary
named "objects".  The entire structure of the project is represented by the
children of this property.  The objects dictionary is keyed by unique 96-bit
values represented by 24 uppercase hexadecimal characters.  Each value in the
objects dictionary is itself a dictionary, describing an individual object.

Each object in the dictionary is a member of a class, which is identified by
the "isa" property of each object.  A variety of classes are represented in a
project file.  Objects can refer to other objects by ID, using the 24-character
hexadecimal object key.  A project's objects form a tree, with a root object
of class PBXProject at the root.  As an example, the PBXProject object serves
as parent to an XCConfigurationList object defining the build configurations
used in the project, a PBXGroup object serving as a container for all files
referenced in the project, and a list of target objects, each of which defines
a target in the project.  There are several different types of target object,
such as PBXNativeTarget and PBXAggregateTarget.  In this module, this
relationship is expressed by having each target type derive from an abstract
base named XCTarget.

The project.pbxproj file's root dictionary also contains a property, sibling to
the "objects" dictionary, named "rootObject".  The value of rootObject is a
24-character object key referring to the root PBXProject object in the
objects dictionary.

In Xcode, every file used as input to a target or produced as a final product
of a target must appear somewhere in the hierarchy rooted at the PBXGroup
object referenced by the PBXProject's mainGroup property.  A PBXGroup is
generally represented as a folder in the Xcode application.  PBXGroups can
contain other PBXGroups as well as PBXFileReferences, which are pointers to
actual files.

Each XCTarget contains a list of build phases, represented in this module by
the abstract base XCBuildPhase.  Examples of concrete XCBuildPhase derivations
are PBXSourcesBuildPhase and PBXFrameworksBuildPhase, which correspond to the
"Compile Sources" and "Link Binary With Libraries" phases displayed in the
Xcode application.  Files used as input to these phases (for example, source
files in the former case and libraries and frameworks in the latter) are
represented by PBXBuildFile objects, referenced by elements of "files" lists
in XCTarget objects.  Each PBXBuildFile object refers to a PBXBuildFile
object as a "weak" reference: it does not "own" the PBXBuildFile, which is
owned by the root object's mainGroup or a descendant group.  In most cases, the
layer of indirection between an XCBuildPhase and a PBXFileReference via a
PBXBuildFile appears extraneous, but there's actually one reason for this:
file-specific compiler flags are added to the PBXBuildFile object so as to
allow a single file to be a member of multiple targets while having distinct
compiler flags for each.  These flags can be modified in the Xcode applciation
in the "Build" tab of a File Info window.

When a project is open in the Xcode application, Xcode will rewrite it.  As
such, this module is careful to adhere to the formatting used by Xcode, to
avoid insignificant changes appearing in the file when it is used in the
Xcode application.  This will keep version control repositories happy, and
makes it possible to compare a project file used in Xcode to one generated by
this module to determine if any significant changes were made in the
application.

Xcode has its own way of assigning 24-character identifiers to each object,
which is not duplicated here.  Because the identifier only is only generated
once, when an object is created, and is then left unchanged, there is no need
to attempt to duplicate Xcode's behavior in this area.  The generator is free
to select any identifier, even at random, to refer to the objects it creates,
and Xcode will retain those identifiers and use them when subsequently
rewriting the project file.  However, the generator would choose new random
identifiers each time the project files are generated, leading to difficulties
comparing "used" project files to "pristine" ones produced by this module,
and causing the appearance of changes as every object identifier is changed
when updated projects are checked in to a version control repository.  To
mitigate this problem, this module chooses identifiers in a more deterministic
way, by hashing a description of each object as well as its parent and ancestor
objects.  This strategy should result in minimal "shift" in IDs as successive
generations of project files are produced.

THIS MODULE

This module introduces several classes, all derived from the XCObject class.
Nearly all of the "brains" are built into the XCObject class, which understands
how to create and modify objects, maintain the proper tree structure, compute
identifiers, and print objects.  For the most part, classes derived from
XCObject need only provide a _schema class object, a dictionary that
expresses what properties objects of the class may contain.

Given this structure, it's possible to build a minimal project file by creating
objects of the appropriate types and making the proper connections:

  config_list = XCConfigurationList()
  group = PBXGroup()
  project = PBXProject({'buildConfigurationList': config_list,
                        'mainGroup': group})

With the project object set up, it can be added to an XCProjectFile object.
XCProjectFile is a pseudo-class in the sense that it is a concrete XCObject
subclass that does not actually correspond to a class type found in a project
file.  Rather, it is used to represent the project file's root dictionary.
Printing an XCProjectFile will print the entire project file, including the
full "objects" dictionary.

  project_file = XCProjectFile({'rootObject': project})
  project_file.ComputeIDs()
  project_file.Print()

Xcode project files are always encoded in UTF-8.  This module will accept
strings of either the str class or the unicode class.  Strings of class str
are assumed to already be encoded in UTF-8.  Obviously, if you're just using
ASCII, you won't encounter difficulties because ASCII is a UTF-8 subset.
Strings of class unicode are handled properly and encoded in UTF-8 when
a project file is output.

    """The abstract base of all class types used in Xcode project files.

  Class variables:
    _schema: A dictionary defining the properties of this class.  The keys to
             _schema are string property keys as used in project files.  Values
             are a list of four or five elements:
             [ is_list, property_type, is_strong, is_required, default ]
             is_list: True if the property described is a list, as opposed
                      to a single element.
             property_type: The type to use as the value of the property,
                            or if is_list is True, the type to use for each
                            element of the value's list.  property_type must
                            be an XCObject subclass, or one of the built-in
                            types str, int, or dict.
             is_strong: If property_type is an XCObject subclass, is_strong
                        is True to assert that this class "owns," or serves
                        as parent, to the property value (or, if is_list is
                        True, values).  is_strong must be False if
                        property_type is not an XCObject subclass.
             is_required: True if the property is required for the class.
                          Note that is_required being True does not preclude
                          an empty string ("", in the case of property_type
                          str) or list ([], in the case of is_list True) from
                          being set for the property.
             default: Optional.  If is_required is True, default may be set
                      to provide a default value for objects that do not supply
                      their own value.  If is_required is True and default
                      is not provided, users of the class must supply their own
                      value for the property.
             Note that although the values of the array are expressed in
             boolean terms, subclasses provide values as integers to conserve
             horizontal space.
    _should_print_single_line: False in XCObject.  Subclasses whose objects
                               should be written to the project file in the
                               alternate single-line format, such as
                               PBXFileReference and PBXBuildFile, should
                               set this to True.
    _encode_transforms: Used by _EncodeString to encode unprintable characters.
                        The index into this list is the ordinal of the
                        character to transform; each value is a string
                        used to represent the character in the output.  XCObject
                        provides an _encode_transforms list suitable for most
                        XCObject subclasses.
    _alternate_encode_transforms: Provided for subclasses that wish to use
                                  the alternate encoding rules.  Xcode seems
                                  to use these rules when printing objects in
                                  single-line format.  Subclasses that desire
                                  this behavior should set _encode_transforms
                                  to _alternate_encode_transforms.
    _hashables: A list of XCObject subclasses that can be hashed by ComputeIDs
                to construct this object's ID.  Most classes that need custom
                hashing behavior should do it by overriding Hashables,
                but in some cases an object's parent may wish to push a
                hashable value into its child, and it can do so by appending
                to _hashables.
  Attributes:
    id: The object's identifier, a 24-character uppercase hexadecimal string.
        Usually, objects being created should not set id until the entire
        project file structure is built.  At that point, UpdateIDs() should
        be called on the root object to assign deterministic values for id to
        each object in the tree.
    parent: The object's parent.  This is set by a parent XCObject when a child
            object is added to it.
    _properties: The object's property dictionary.  An object's properties are
                 described by its class' _schema variable.

    XCHierarchicalElements are special.  Generally, their hashes shouldn't
    change if the paths don't change.  The normal XCObject implementation of
    Hashables adds a hashable for each object, which means that if
    the hierarchical structure changes (possibly due to changes caused when
    TakeOverOnlyChild runs and encounters slight changes in the hierarchy),
    the hashes will change.  For example, if a project file initially contains
    a/b/f1 and a/b becomes collapsed into a/b, f1 will have a single parent
    a/b.  If someone later adds a/f2 to the project file, a/b can no longer be
    collapsed, and f1 winds up with parent b and grandparent a.  That would
    be sufficient to change f1's hash.

    To counteract this problem, hashables for all XCHierarchicalElements except
    for the main group (which has neither a name nor a path) are taken to be
    just the set of path components.  Because hashables are inherited from
    parents, this provides assurance that a/b/f1 has the same set of hashables
    whether its parent is b or a/b.

    The main group is a special case.  As it is permitted to have no name or
    path, it is permitted to use the standard XCObject hash mechanism.  This
    is not considered a problem because there can be only one main group.

      Object form, made available under the License, as indicated by a
      copyright notice that is included in or attached to the work
      (an example is provided in the Appendix below).

      "Derivative Works" shall mean any work, whether in Source or Object
      form, that is based on (or derived from) the Work and for which the
      editorial revisions, annotations, elaborations, or other modifications
      represent, as a whole, an original work of authorship. For the purposes
      of this License, Derivative Works shall not include works that remain
      separable from, or merely link (or bind by name) to the interfaces of,
      the Work and Derivative Works thereof.

      "Contribution" shall mean any work of authorship, including

      "Contributor" shall mean Licensor and any individual or Legal Entity
      on behalf of whom a Contribution has been received by Licensor and

      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      copyright license to reproduce, prepare Derivative Works of,
      publicly display, publicly perform, sublicense, and distribute the
      Work and such Derivative Works in Source or Object form.

   3. Grant of Patent License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      (except as stated in this section) patent license to make, have made,
      use, offer to sell, sell, import, and otherwise transfer the Work,
      where such license applies only to those patent claims licensable
      by such Contributor that are necessarily infringed by their
      Contribution(s) alone or by combination of their Contribution(s)
      with the Work to which such Contribution(s) was submitted. If You
      institute patent litigation against any entity (including a
      cross-claim or counterclaim in a lawsuit) alleging that the Work
      or a Contribution incorporated within the Work constitutes direct
      or contributory patent infringement, then any patent licenses
      granted to You under this License for that Work shall terminate
      as of the date such litigation is filed.

   4. Redistribution. You may reproduce and distribute copies of the
      Work or Derivative Works thereof in any medium, with or without
      modifications, and in Source or Object form, provided that You
      meet the following conditions:

      (a) You must give any other recipients of the Work or
          Derivative Works a copy of this License; and

      (b) You must cause any modified files to carry prominent notices
          stating that You changed the files; and

      (c) You must retain, in the Source form of any Derivative Works
          that You distribute, all copyright, patent, trademark, and
          attribution notices from the Source form of the Work,
          excluding those notices that do not pertain to any part of
          the Derivative Works; and

      (d) If the Work includes a "NOTICE" text file as part of its
          distribution, then any Derivative Works that You distribute must
          include a readable copy of the attribution notices contained
          within such NOTICE file, excluding those notices that do not
          pertain to any part of the Derivative Works, in at least one
          of the following places: within a NOTICE text file distributed
          as part of the Derivative Works; within the Source form or
          documentation, if provided along with the Derivative Works; or,
          within a display generated by the Derivative Works, if and
          wherever such third-party notices normally appear. The contents
          of the NOTICE file are for informational purposes only and
          do not modify the License. You may add Your own attribution
          notices within Derivative Works that You distribute, alongside
          or as an addendum to the NOTICE text from the Work, provided
          that such additional attribution notices cannot be construed
          as modifying the License.

      You may add Your own copyright statement to Your modifications and
      may provide additional or different license terms and conditions
      for use, reproduction, or distribution of Your modifications, or
      for any such Derivative Works as a whole, provided Your use,
      reproduction, and distribution of the Work otherwise complies with
      the conditions stated in this License.

   5. Submission of Contributions. Unless You explicitly state otherwise,
      any Contribution intentionally submitted for inclusion in the Work
      by You to the Licensor shall be under the terms and conditions of
      this License, without any additional terms or conditions.
      Notwithstanding the above, nothing herein shall supersede or modify
      the terms of any separate license agreement you may have executed
      with Licensor regarding such Contributions.

   6. Trademarks. This License does not grant permission to use the trade
      names, trademarks, service marks, or product names of the Licensor,
      except as required for reasonable and customary use in describing the
      origin of the Work and reproducing the content of the NOTICE file.

   7. Disclaimer of Warranty. Unless required by applicable law or
      agreed to in writing, Licensor provides the Work (and each
      Contributor provides its Contributions) on an "AS IS" BASIS,
      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
      implied, including, without limitation, any warranties or conditions
      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
      PARTICULAR PURPOSE. You are solely responsible for determining the
      appropriateness of using or redistributing the Work and assume any
      risks associated with Your exercise of permissions under this License.

   8. Limitation of Liability. In no event and under no legal theory,
      whether in tort (including negligence), contract, or otherwise,
      unless required by applicable law (such as deliberate and grossly
      negligent acts) or agreed to in writing, shall any Contributor be
      liable to You for damages, including any direct, indirect, special,
      incidental, or consequential damages of any character arising as a
      result of this License or out of the use or inability to use the
      Work (including but not limited to damages for loss of goodwill,
      work stoppage, computer failure or malfunction, or any and all
      other commercial damages or losses), even if such Contributor
      has been advised of the possibility of such damages.

   9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
      of your accepting any such warranty or additional liability.

# mkdirp

Like `mkdir -p`, but in Node.js!

Now with a modern API and no\* bugs!

<small>\* may contain some bugs</small>

# example

## pow.js

```js
// hybrid module, import or require() both work
import { mkdirp } from 'mkdirp'
// or:
const { mkdirp } = require('mkdirp')

// return value is a Promise resolving to the first directory created
mkdirp('/tmp/foo/bar/baz').then(made =>
  console.log(`made directories, starting with ${made}`)
)
```

Output (where `/tmp/foo` already exists)

```
made directories, starting with /tmp/foo/bar
```

Or, if you don't have time to wait around for promises:

```js
import { mkdirp } from 'mkdirp'

// return value is the first directory created
const made = mkdirp.sync('/tmp/foo/bar/baz')
console.log(`made directories, starting with ${made}`)
```

And now /tmp/foo/bar/baz exists, huzzah!

# methods

```js
import { mkdirp } from 'mkdirp'
```

## `mkdirp(dir: string, opts?: MkdirpOptions) => Promise<string | undefined>`

Create a new directory and any necessary subdirectories at `dir`
with octal permission string `opts.mode`. If `opts` is a string
or number, it will be treated as the `opts.mode`.

If `opts.mode` isn't specified, it defaults to `0o777`.

Promise resolves to first directory `made` that had to be
created, or `undefined` if everything already exists. Promise
rejects if any errors are encountered. Note that, in the case of
promise rejection, some directories _may_ have been created, as
recursive directory creation is not an atomic operation.

You can optionally pass in an alternate `fs` implementation by
passing in `opts.fs`. Your implementation should have
`opts.fs.mkdir(path, opts, cb)` and `opts.fs.stat(path, cb)`.

You can also override just one or the other of `mkdir` and `stat`
by passing in `opts.stat` or `opts.mkdir`, or providing an `fs`
option that only overrides one of these.

## `mkdirp.sync(dir: string, opts: MkdirpOptions) => string|undefined`

Synchronously create a new directory and any necessary
subdirectories at `dir` with octal permission string `opts.mode`.
If `opts` is a string or number, it will be treated as the
`opts.mode`.

If `opts.mode` isn't specified, it defaults to `0o777`.

Returns the first directory that had to be created, or undefined
if everything already exists.

You can optionally pass in an alternate `fs` implementation by
passing in `opts.fs`. Your implementation should have
`opts.fs.mkdirSync(path, mode)` and `opts.fs.statSync(path)`.

You can also override just one or the other of `mkdirSync` and
`statSync` by passing in `opts.statSync` or `opts.mkdirSync`, or
providing an `fs` option that only overrides one of these.

## `mkdirp.manual`, `mkdirp.manualSync`

Use the manual implementation (not the native one). This is the
default when the native implementation is not available or the
stat/mkdir implementation is overridden.

## `mkdirp.native`, `mkdirp.nativeSync`

Use the native implementation (not the manual one). This is the
default when the native implementation is available and
stat/mkdir are not overridden.

# implementation

On Node.js v10.12.0 and above, use the native `fs.mkdir(p,
{recursive:true})` option, unless `fs.mkdir`/`fs.mkdirSync` has
been overridden by an option.

## native implementation

- If the path is a root directory, then pass it to the underlying
  implementation and return the result/error. (In this case,
  it'll either succeed or fail, but we aren't actually creating
  any dirs.)
- Walk up the path statting each directory, to find the first
  path that will be created, `made`.
- Call `fs.mkdir(path, { recursive: true })` (or `fs.mkdirSync`)
- If error, raise it to the caller.
- Return `made`.

## manual implementation

- Call underlying `fs.mkdir` implementation, with `recursive:
false`
- If error:
  - If path is a root directory, raise to the caller and do not
    handle it
  - If ENOENT, mkdirp parent dir, store result as `made`
  - stat(path)
    - If error, raise original `mkdir` error
    - If directory, return `made`
    - Else, raise original `mkdir` error
- else
  - return `undefined` if a root dir, or `made` if set, or `path`

## windows vs unix caveat

On Windows file systems, attempts to create a root directory (ie,
a drive letter or root UNC path) will fail. If the root
directory exists, then it will fail with `EPERM`. If the root
directory does not exist, then it will fail with `ENOENT`.

On posix file systems, attempts to create a root directory (in
recursive mode) will succeed silently, as it is treated like just
another directory that already exists. (In non-recursive mode,
of course, it fails with `EEXIST`.)

In order to preserve this system-specific behavior (and because
it's not as if we can create the parent of a root directory
anyway), attempts to create a root directory are passed directly
to the `fs` implementation, and any errors encountered are not
handled.

## native error caveat

The native implementation (as of at least Node.js v13.4.0) does
not provide appropriate errors in some cases (see
[nodejs/node#31481](https://github.com/nodejs/node/issues/31481)
and
[nodejs/node#28015](https://github.com/nodejs/node/issues/28015)).

In order to work around this issue, the native implementation
will fall back to the manual implementation if an `ENOENT` error
is encountered.

# choosing a recursive mkdir implementation

There are a few to choose from! Use the one that suits your
needs best :D

## use `fs.mkdir(path, {recursive: true}, cb)` if:

- You wish to optimize performance even at the expense of other
  factors.
- You don't need to know the first dir created.
- You are ok with getting `ENOENT` as the error when some other
  problem is the actual cause.
- You can limit your platforms to Node.js v10.12 and above.
- You're ok with using callbacks instead of promises.
- You don't need/want a CLI.
- You don't need to override the `fs` methods in use.

## use this module (mkdirp 1.x or 2.x) if:

- You need to know the first directory that was created.
- You wish to use the native implementation if available, but
  fall back when it's not.
- You prefer promise-returning APIs to callback-taking APIs.
- You want more useful error messages than the native recursive
  mkdir provides (at least as of Node.js v13.4), and are ok with
  re-trying on `ENOENT` to achieve this.
- You need (or at least, are ok with) a CLI.
- You need to override the `fs` methods in use.

## use [`make-dir`](http://npm.im/make-dir) if:

- You do not need to know the first dir created (and wish to save
  a few `stat` calls when using the native implementation for
  this reason).
- You wish to use the native implementation if available, but
  fall back when it's not.
- You prefer promise-returning APIs to callback-taking APIs.
- You are ok with occasionally getting `ENOENT` errors for
  failures that are actually related to something other than a
  missing file system entry.
- You don't need/want a CLI.
- You need to override the `fs` methods in use.

## use mkdirp 0.x if:

- You need to know the first directory that was created.
- You need (or at least, are ok with) a CLI.
- You need to override the `fs` methods in use.
- You're ok with using callbacks instead of promises.
- You are not running on Windows, where the root-level ENOENT
  errors can lead to infinite regress.
- You think vinyl just sounds warmer and richer for some weird
  reason.
- You are supporting truly ancient Node.js versions, before even
  the advent of a `Promise` language primitive. (Please don't.
  You deserve better.)

# cli

This package also ships with a `mkdirp` command.

```
$ mkdirp -h

usage: mkdirp [DIR1,DIR2..] {OPTIONS}

  Create each supplied directory including any necessary parent directories
  that don't yet exist.

  If the directory already exists, do nothing.

OPTIONS are:

  -m<mode>       If a directory needs to be created, set the mode as an octal
  --mode=<mode>  permission string.

  -v --version   Print the mkdirp version number

  -h --help      Print this helpful banner

  -p --print     Print the first directories created for each path provided

  --manual       Use manual implementation, even if native is available
```

# install

With [npm](http://npmjs.org) do:

```
npm install mkdirp
```

to get the library locally, or

```
npm install -g mkdirp
```

to get the command everywhere, or

```
npx mkdirp ...
```

to run the command without installing it globally.

# platform support

This module works on node v8, but only v10 and above are officially
supported, as Node v8 reached its LTS end of life 2020-01-01, which is in
the past, as of this writing.

If you want to write an option parser, and have it be good, there are
two ways to do it.  The Right Way, and the Wrong Way.

The Wrong Way is to sit down and write an option parser.  We've all done
that.

The Right Way is to write some complex configurable program with so many
options that you hit the limit of your frustration just trying to
manage them all, and defer it with duct-tape solutions until you see
exactly to the core of the problem, and finally snap and write an
awesome option parser.

If you want to write an option parser, don't write an option parser.
Write a package manager, or a source control system, or a service
restarter, or an operating system.  You probably won't end up with a
good one of those, but if you don't give up, and you are relentless and
diligent enough in your procrastination, you may just end up with a very
nice option parser.

## USAGE

```javascript
// my-program.js
var nopt = require("nopt")
  , Stream = require("stream").Stream
  , path = require("path")
  , knownOpts = { "foo" : [String, null]
                , "bar" : [Stream, Number]
                , "baz" : path
                , "bloo" : [ "big", "medium", "small" ]
                , "flag" : Boolean
                , "pick" : Boolean
                , "many1" : [String, Array]
                , "many2" : [path, Array]
                }
  , shortHands = { "foofoo" : ["--foo", "Mr. Foo"]
                 , "b7" : ["--bar", "7"]
                 , "m" : ["--bloo", "medium"]
                 , "p" : ["--pick"]
                 , "f" : ["--flag"]
                 }
             // everything is optional.
             // knownOpts and shorthands default to {}
             // arg list defaults to process.argv
             // slice defaults to 2
  , parsed = nopt(knownOpts, shortHands, process.argv, 2)
console.log(parsed)
```

This would give you support for any of the following:

```console
$ node my-program.js --foo "blerp" --no-flag
{ "foo" : "blerp", "flag" : false }

$ node my-program.js ---bar 7 --foo "Mr. Hand" --flag
{ bar: 7, foo: "Mr. Hand", flag: true }

$ node my-program.js --foo "blerp" -f -----p
{ foo: "blerp", flag: true, pick: true }

$ node my-program.js -fp --foofoo
{ foo: "Mr. Foo", flag: true, pick: true }

$ node my-program.js --foofoo -- -fp  # -- stops the flag parsing.
{ foo: "Mr. Foo", argv: { remain: ["-fp"] } }

$ node my-program.js --blatzk -fp # unknown opts are ok.
{ blatzk: true, flag: true, pick: true }

$ node my-program.js --blatzk=1000 -fp # but you need to use = if they have a value
{ blatzk: 1000, flag: true, pick: true }

$ node my-program.js --no-blatzk -fp # unless they start with "no-"
{ blatzk: false, flag: true, pick: true }

$ node my-program.js --baz b/a/z # known paths are resolved.
{ baz: "/Users/isaacs/b/a/z" }

# if Array is one of the types, then it can take many
# values, and will always be an array.  The other types provided
# specify what types are allowed in the list.

$ node my-program.js --many1 5 --many1 null --many1 foo
{ many1: ["5", "null", "foo"] }

$ node my-program.js --many2 foo --many2 bar
{ many2: ["/path/to/foo", "path/to/bar"] }
```

Read the tests at the bottom of `lib/nopt.js` for more examples of
what this puppy can do.

## Types

The following types are supported, and defined on `nopt.typeDefs`

* String: A normal string.  No parsing is done.
* path: A file system path.  Gets resolved against cwd if not absolute.
* url: A url.  If it doesn't parse, it isn't accepted.
* Number: Must be numeric.
* Date: Must parse as a date. If it does, and `Date` is one of the options,
  then it will return a Date object, not a string.
* Boolean: Must be either `true` or `false`.  If an option is a boolean,
  then it does not need a value, and its presence will imply `true` as
  the value.  To negate boolean flags, do `--no-whatever` or `--whatever
  false`
* NaN: Means that the option is strictly not allowed.  Any value will
  fail.
* Stream: An object matching the "Stream" class in node.  Valuable
  for use when validating programmatically.  (npm uses this to let you
  supply any WriteStream on the `outfd` and `logfd` config options.)
* Array: If `Array` is specified as one of the types, then the value
  will be parsed as a list of options.  This means that multiple values
  can be specified, and that the value will always be an array.

If a type is an array of values not on this list, then those are
considered valid values.  For instance, in the example above, the
`--bloo` option can only be one of `"big"`, `"medium"`, or `"small"`,
and any other value will be rejected.

When parsing unknown fields, `"true"`, `"false"`, and `"null"` will be
interpreted as their JavaScript equivalents.

You can also mix types and values, or multiple types, in a list.  For
instance `{ blah: [Number, null] }` would allow a value to be set to
either a Number or null.  When types are ordered, this implies a
preference, and the first type that can be used to properly interpret
the value will be used.

To define a new type, add it to `nopt.typeDefs`.  Each item in that
hash is an object with a `type` member and a `validate` method.  The
`type` member is an object that matches what goes in the type list.  The
`validate` method is a function that gets called with `validate(data,
key, val)`.  Validate methods should assign `data[key]` to the valid
value of `val` if it can be handled properly, or return boolean
`false` if it cannot.

You can also call `nopt.clean(data, types, typeDefs)` to clean up a
config object and remove its invalid properties.

## Error Handling

By default, nopt outputs a warning to standard error when invalid values for
known options are found.  You can change this behavior by assigning a method
to `nopt.invalidHandler`.  This method will be called with
the offending `nopt.invalidHandler(key, val, types)`.

If no `nopt.invalidHandler` is assigned, then it will console.error
its whining.  If it is assigned to boolean `false` then the warning is
suppressed.

## Abbreviations

Yes, they are supported.  If you define options like this:

```javascript
{ "foolhardyelephants" : Boolean
, "pileofmonkeys" : Boolean }
```

Then this will work:

```bash
node program.js --foolhar --pil
node program.js --no-f --pileofmon
# etc.
```

## Shorthands

Shorthands are a hash of shorter option names to a snippet of args that
they expand to.

If multiple one-character shorthands are all combined, and the
combination does not unambiguously match any other option or shorthand,
then they will be broken up into their constituent parts.  For example:

```json
{ "s" : ["--loglevel", "silent"]
, "g" : "--global"
, "f" : "--force"
, "p" : "--parseable"
, "l" : "--long"
}
```

```bash
npm ls -sgflp
# just like doing this:
npm ls --loglevel silent --global --force --long --parseable
```

## The Rest of the args

The config object returned by nopt is given a special member called
`argv`, which is an object with the following fields:

* `remain`: The remaining args after all the parsing has occurred.
* `original`: The args as they originally appeared.
* `cooked`: The args after flags and shorthands are expanded.

## Slicing

Node programs are called with more or less the exact argv as it appears
in C land, after the v8 and node-specific options have been plucked off.
As such, `argv[0]` is always `node` and `argv[1]` is always the
JavaScript program being run.

That's usually not very useful to you.  So they're sliced off by
default.  If you want them, then you can pass in `0` as the last
argument, or any other number that you'd like to slice off the start of
the list.

# pacote

Fetches package manifests and tarballs from the npm registry.

## USAGE

```js
const pacote = require('pacote')

// get a package manifest
pacote.manifest('foo@1.x').then(manifest => console.log('got it', manifest))

// extract a package into a folder
pacote.extract('github:npm/cli', 'some/path', options)
  .then(({from, resolved, integrity}) => {
    console.log('extracted!', from, resolved, integrity)
  })

pacote.tarball('https://server.com/package.tgz').then(data => {
  console.log('got ' + data.length + ' bytes of tarball data')
})
```

`pacote` works with any kind of package specifier that npm can install.  If
you can pass it to the npm CLI, you can pass it to pacote.  (In fact, that's
exactly what the npm CLI does.)

Anything that you can do with one kind of package, you can do with another.

Data that isn't relevant (like a packument for a tarball) will be
simulated.

`prepare` scripts will be run when generating tarballs from `git` and
`directory` locations, to simulate what _would_ be published to the
registry, so that you get a working package instead of just raw source
code that might need to be transpiled.

## CLI

This module exports a command line interface that can do most of what is
described below.  Run `pacote -h` to learn more.

```
Pacote - The JavaScript Package Handler, v10.1.1

Usage:

  pacote resolve <spec>
    Resolve a specifier and output the fully resolved target
    Returns integrity and from if '--long' flag is set.

  pacote manifest <spec>
    Fetch a manifest and print to stdout

  pacote packument <spec>
    Fetch a full packument and print to stdout

  pacote tarball <spec> [<filename>]
    Fetch a package tarball and save to <filename>
    If <filename> is missing or '-', the tarball will be streamed to stdout.

  pacote extract <spec> <folder>
    Extract a package to the destination folder.

Configuration values all match the names of configs passed to npm, or
options passed to Pacote.  Additional flags for this executable:

  --long     Print an object from 'resolve', including integrity and spec.
  --json     Print result objects as JSON rather than node's default.
             (This is the default if stdout is not a TTY.)
  --help -h  Print this helpful text.

For example '--cache=/path/to/folder' will use that folder as the cache.
```

## API

The `spec` refers to any kind of package specifier that npm can install.
If you can pass it to the npm CLI, you can pass it to pacote.  (In fact,
that's exactly what the npm CLI does.)

See below for valid `opts` values.

* `pacote.resolve(spec, opts)` Resolve a specifier like `foo@latest` or
  `github:user/project` all the way to a tarball url, tarball file, or git
  repo with commit hash.

* `pacote.extract(spec, dest, opts)` Extract a package's tarball into a
  destination folder.  Returns a promise that resolves to the
  `{from,resolved,integrity}` of the extracted package.

* `pacote.manifest(spec, opts)` Fetch (or simulate) a package's manifest
  (basically, the `package.json` file, plus a bit of metadata).
  See below for more on manifests and packuments.  Returns a Promise that
  resolves to the manifest object.

* `pacote.packument(spec, opts)` Fetch (or simulate) a package's packument
  (basically, the top-level package document listing all the manifests that
  the registry returns).  See below for more on manifests and packuments.
  Returns a Promise that resolves to the packument object.

* `pacote.tarball(spec, opts)`  Get a package tarball data as a buffer in
  memory.  Returns a Promise that resolves to the tarball data Buffer, with
  `from`, `resolved`, and `integrity` fields attached.

* `pacote.tarball.file(spec, dest, opts)`  Save a package tarball data to
  a file on disk.  Returns a Promise that resolves to
  `{from,integrity,resolved}` of the fetched tarball.

* `pacote.tarball.stream(spec, streamHandler, opts)`  Fetch a tarball and
  make the stream available to the `streamHandler` function.

    This is mostly an internal function, but it is exposed because it does
    provide some functionality that may be difficult to achieve otherwise.

    The `streamHandler` function MUST return a Promise that resolves when
    the stream (and all associated work) is ended, or rejects if the stream
    has an error.

    The `streamHandler` function MAY be called multiple times, as Pacote
    retries requests in some scenarios, such as cache corruption or
    retriable network failures.

### Options

Options are passed to
[`npm-registry-fetch`](http://npm.im/npm-registry-fetch) and
[`cacache`](http://npm.im/cacache), so in addition to these, anything for
those modules can be given to pacote as well.

Options object is cloned, and mutated along the way to add integrity,
resolved, and other properties, as they are determined.

* `cache` Where to store cache entries and temp files.  Passed to
  [`cacache`](http://npm.im/cacache).  Defaults to the same cache directory
  that npm will use by default, based on platform and environment.
* `where` Base folder for resolving relative `file:` dependencies.
* `resolved` Shortcut for looking up resolved values.  Should be specified
  if known.
* `integrity` Expected integrity of fetched package tarball.  If specified,
  tarballs with mismatched integrity values will raise an `EINTEGRITY`
  error.
* `umask` Permission mode mask for extracted files and directories.
  Defaults to `0o22`.  See "Extracted File Modes" below.
* `fmode` Minimum permission mode for extracted files.  Defaults to
  `0o666`.  See "Extracted File Modes" below.
* `dmode` Minimum permission mode for extracted directories.  Defaults to
  `0o777`.  See "Extracted File Modes" below.
* `preferOnline` Prefer to revalidate cache entries, even when it would not
  be strictly necessary.  Default `false`.
* `before` When picking a manifest from a packument, only consider
  packages published before the specified date.  Default `null`.
* `defaultTag` The default `dist-tag` to use when choosing a manifest from a
  packument.  Defaults to `latest`.
* `registry` The npm registry to use by default.  Defaults to
  `https://registry.npmjs.org/`.
* `fullMetadata` Fetch the full metadata from the registry for packuments,
  including information not strictly required for installation (author,
  description, etc.)  Defaults to `true` when `before` is set, since the
  version publish time is part of the extended packument metadata.
* `fullReadJson` Use the slower `read-package-json` package insted of
  `read-package-json-fast` in order to include extra fields like "readme" in
  the manifest. Defaults to `false`.
* `packumentCache` For registry packuments only, you may provide a `Map`
  object which will be used to cache packument requests between pacote
  calls.  This allows you to easily avoid hitting the registry multiple
  times (even just to validate the cache) for a given packument, since it
  is unlikely to change in the span of a single command.
* `verifySignatures` A boolean that will make pacote verify the
    integrity signature of a manifest, if present.  There must be a
    configured `_keys` entry in the config that is scoped to the
    registry the manifest is being fetched from.
* `verifyAttestations` A boolean that will make pacote verify Sigstore
    attestations, if present. There must be a configured `_keys` entry in the
    config that is scoped to the registry the manifest is being fetched from.
* `tufCache` Where to store metadata/target files when retrieving the package
  attestation key material via TUF. Defaults to the same cache directory that
  npm will use by default, based on platform and environment.

### Advanced API

Each different type of fetcher is exposed for more advanced usage such as
using helper methods from this classes:

* `DirFetcher`
* `FileFetcher`
* `GitFetcher`
* `RegistryFetcher`
* `RemoteFetcher`

## Extracted File Modes

Files are extracted with a mode matching the following formula:

```
( (tarball entry mode value) | (minimum mode option) ) ~ (umask)
```

This is in order to prevent unreadable files or unlistable directories from
cluttering a project's `node_modules` folder, even if the package tarball
specifies that the file should be inaccessible.

It also prevents files from being group- or world-writable without explicit
opt-in by the user, because all file and directory modes are masked against
the `umask` value.

So, a file which is `0o771` in the tarball, using the default `fmode` of
`0o666` and `umask` of `0o22`, will result in a file mode of `0o755`:

```
(0o771 | 0o666) => 0o777
(0o777 ~ 0o22) => 0o755
```

In almost every case, the defaults are appropriate.  To respect exactly
what is in the package tarball (even if this makes an unusable system), set
both `dmode` and `fmode` options to `0`.  Otherwise, the `umask` config
should be used in most cases where file mode modifications are required,
and this functions more or less the same as the `umask` value in most Unix
systems.

## Extracted File Ownership

When running as `root` on Unix systems, all extracted files and folders
will have their owning `uid` and `gid` values set to match the ownership
of the containing folder.

This prevents `root`-owned files showing up in a project's `node_modules`
folder when a user runs `sudo npm install`.

## Manifests

A `manifest` is similar to a `package.json` file.  However, it has a few
pieces of extra metadata, and sometimes lacks metadata that is inessential
to package installation.

In addition to the common `package.json` fields, manifests include:

* `manifest._resolved` The tarball url or file path where the package
  artifact can be found.
* `manifest._from` A normalized form of the spec passed in as an argument.
* `manifest._integrity` The integrity value for the package artifact.
* `manifest._id` The canonical spec of this package version: name@version.
* `manifest.dist` Registry manifests (those included in a packument) have a
  `dist` object.  Only `tarball` is required, though at least one of
  `shasum` or `integrity` is almost always present.

    * `tarball` The url to the associated package artifact.  (Copied by
      Pacote to `manifest._resolved`.)
    * `integrity` The integrity SRI string for the artifact.  This may not
      be present for older packages on the npm registry.  (Copied by Pacote
      to `manifest._integrity`.)
    * `shasum` Legacy integrity value.  Hexadecimal-encoded sha1 hash.
      (Converted to an SRI string and copied by Pacote to
      `manifest._integrity` when `dist.integrity` is not present.)
    * `fileCount` Number of files in the tarball.
    * `unpackedSize` Size on disk of the package when unpacked.
    * `signatures` Signatures of the shasum.  Includes the keyid that
        correlates to a [`key from the npm
        registry`](https://registry.npmjs.org/-/npm/v1/keys)

## Packuments

A packument is the top-level package document that lists the set of
manifests for available versions for a package.

When a packument is fetched with `accept:
application/vnd.npm.install-v1+json` in the HTTP headers, only the most
minimum necessary metadata is returned.  Additional metadata is returned
when fetched with only `accept: application/json`.

For Pacote's purposes, the following fields are relevant:

* `versions` An object where each key is a version, and each value is the
  manifest for that version.
* `dist-tags` An object mapping dist-tags to version numbers.  This is how
  `foo@latest` gets turned into `foo@1.2.3`.
* `time` In the full packument, an object mapping version numbers to
  publication times, for the `opts.before` functionality.

Pacote adds the following field, regardless of the accept header:

* `_contentLength` The size of the packument.

# API Documentation

*Please use only this documented API when working with the parser. Methods
not documented here are subject to change at any point.*

## `parser` function

This is the module's main entry point.

```js
const parser = require('postcss-selector-parser');
```

### `parser([transform], [options])`

Creates a new `processor` instance

```js
const processor = parser();
```

Or, with optional transform function

```js
const transform = selectors => {
    selectors.walkUniversals(selector => {
        selector.remove();
    });
};

const processor = parser(transform)

// Example
const result = processor.processSync('*.class');
// => .class
```

[See processor documentation](#processor)

Arguments:

* `transform (function)`: Provide a function to work with the parsed AST.
* `options (object)`: Provide default options for all calls on the returned `Processor`.

### `parser.attribute([props])`

Creates a new attribute selector.

```js
parser.attribute({attribute: 'href'});
// => [href]
```

Arguments:

* `props (object)`: The new node's properties.

### `parser.className([props])`

Creates a new class selector.

```js
parser.className({value: 'button'});
// => .button
```

Arguments:

* `props (object)`: The new node's properties.

### `parser.combinator([props])`

Creates a new selector combinator.

```js
parser.combinator({value: '+'});
// => +
```

Arguments:

* `props (object)`: The new node's properties.

Notes:
* **Descendant Combinators** The value of descendant combinators created by the
  parser always just a single space (`" "`). For descendant selectors with no
  comments, additional space is now stored in `node.spaces.before`. Depending
  on the location of comments, additional spaces may be stored in
  `node.raws.spaces.before`, `node.raws.spaces.after`, or `node.raws.value`.
* **Named Combinators** Although, nonstandard and unlikely to ever become a standard,
  named combinators like `/deep/` and `/for/` are parsed as combinators. The
  `node.value` is name after being unescaped and normalized as lowercase. The
  original value for the combinator name is stored in `node.raws.value`.


### `parser.comment([props])`

Creates a new comment.

```js
parser.comment({value: '/* Affirmative, Dave. I read you. */'});
// => /* Affirmative, Dave. I read you. */
```

Arguments:

* `props (object)`: The new node's properties.

### `parser.id([props])`

Creates a new id selector.

```js
parser.id({value: 'search'});
// => #search
```

Arguments:

* `props (object)`: The new node's properties.

### `parser.nesting([props])`

Creates a new nesting selector.

```js
parser.nesting();
// => &
```

Arguments:

* `props (object)`: The new node's properties.

### `parser.pseudo([props])`

Creates a new pseudo selector.

```js
parser.pseudo({value: '::before'});
// => ::before
```

Arguments:

* `props (object)`: The new node's properties.

### `parser.root([props])`

Creates a new root node.

```js
parser.root();
// => (empty)
```

Arguments:

* `props (object)`: The new node's properties.

### `parser.selector([props])`

Creates a new selector node.

```js
parser.selector();
// => (empty)
```

Arguments:

* `props (object)`: The new node's properties.

### `parser.string([props])`

Creates a new string node.

```js
parser.string();
// => (empty)
```

Arguments:

* `props (object)`: The new node's properties.

### `parser.tag([props])`

Creates a new tag selector.

```js
parser.tag({value: 'button'});
// => button
```

Arguments:

* `props (object)`: The new node's properties.

### `parser.universal([props])`

Creates a new universal selector.

```js
parser.universal();
// => *
```

Arguments:

* `props (object)`: The new node's properties.

## Node types

### `node.type`

A string representation of the selector type. It can be one of the following;
`attribute`, `class`, `combinator`, `comment`, `id`, `nesting`, `pseudo`,
`root`, `selector`, `string`, `tag`, or `universal`. Note that for convenience,
these constants are exposed on the main `parser` as uppercased keys. So for
example you can get `id` by querying `parser.ID`.

```js
parser.attribute({attribute: 'href'}).type;
// => 'attribute'
```

### `node.parent`

Returns the parent node.

```js
root.nodes[0].parent === root;
```

### `node.toString()`, `String(node)`, or `'' + node`

Returns a string representation of the node.

```js
const id = parser.id({value: 'search'});
console.log(String(id));
// => #search
```

### `node.next()` & `node.prev()`

Returns the next/previous child of the parent node.

```js
const next = id.next();
if (next && next.type !== 'combinator') {
    throw new Error('Qualified IDs are not allowed!');
}
```

### `node.replaceWith(node)`

Replace a node with another.

```js
const attr = selectors.first.first;
const className = parser.className({value: 'test'});
attr.replaceWith(className);
```

Arguments:

* `node`: The node to substitute the original with.

### `node.remove()`

Removes the node from its parent node.

```js
if (node.type === 'id') {
    node.remove();
}
```

### `node.clone([opts])`

Returns a copy of a node, detached from any parent containers that the
original might have had.

```js
const cloned = node.clone();
```

### `node.isAtPosition(line, column)`

Return a `boolean` indicating whether this node includes the character at the
position of the given line and column. Returns `undefined` if the nodes lack
sufficient source metadata to determine the position.

Arguments:

* `line`: 1-index based line number relative to the start of the selector.
* `column`: 1-index based column number relative to the start of the selector.

### `node.spaces`

Extra whitespaces around the node will be moved into `node.spaces.before` and
`node.spaces.after`. So for example, these spaces will be moved as they have
no semantic meaning:

```css
      h1     ,     h2   {}
```

For descendent selectors, the value is always a single space.

```css
h1        h2 {}
```

Additional whitespace is found in either the `node.spaces.before` and `node.spaces.after` depending on the presence of comments or other whitespace characters. If the actual whitespace does not start or end with a single space, the node's raw value is set to the actual space(s) found in the source.

### `node.source`

An object describing the node's start/end, line/column source position.

Within the following CSS, the `.bar` class node ...

```css
.foo,
  .bar {}
```

... will contain the following `source` object.

```js
source: {
    start: {
        line: 2,
        column: 3
    },
    end: {
        line: 2,
        column: 6
    }
}
```

### `node.sourceIndex`

The zero-based index of the node within the original source string.

Within the following CSS, the `.baz` class node will have a `sourceIndex` of `12`.

```css
.foo, .bar, .baz {}
```

## Container types

The `root`, `selector`, and `pseudo` nodes have some helper methods for working
with their children.

### `container.nodes`

An array of the container's children.

```js
// Input: h1 h2
selectors.at(0).nodes.length   // => 3
selectors.at(0).nodes[0].value // => 'h1'
selectors.at(0).nodes[1].value // => ' '
```

### `container.first` & `container.last`

The first/last child of the container.

```js
selector.first === selector.nodes[0];
selector.last === selector.nodes[selector.nodes.length - 1];
```

### `container.at(index)`

Returns the node at position `index`.

```js
selector.at(0) === selector.first;
selector.at(0) === selector.nodes[0];
```

Arguments:

* `index`: The index of the node to return.

### `container.atPosition(line, column)`

Returns the node at the source position `line` and `column`.

```js
// Input: :not(.foo),\n#foo > :matches(ol, ul)
selector.atPosition(1, 1); // => :not(.foo)
selector.atPosition(2, 1); // => \n#foo
```

Arguments:

* `line`: The line number of the node to return.
* `column`: The column number of the node to return.

### `container.index(node)`

Return the index of the node within its container.

```js
selector.index(selector.nodes[2]) // => 2
```

Arguments:

* `node`: A node within the current container.

### `container.length`

Proxy to the length of the container's nodes.

```js
container.length === container.nodes.length
```

### `container` Array iterators

The container class provides proxies to certain Array methods; these are:

* `container.map === container.nodes.map`
* `container.reduce === container.nodes.reduce`
* `container.every === container.nodes.every`
* `container.some === container.nodes.some`
* `container.filter === container.nodes.filter`
* `container.sort === container.nodes.sort`

Note that these methods only work on a container's immediate children; recursive
iteration is provided by `container.walk`.

### `container.each(callback)`

Iterate the container's immediate children, calling `callback` for each child.
You may return `false` within the callback to break the iteration.

```js
let className;
selectors.each((selector, index) => {
    if (selector.type === 'class') {
        className = selector.value;
        return false;
    }
});
```

Note that unlike `Array#forEach()`, this iterator is safe to use whilst adding
or removing nodes from the container.

Arguments:

* `callback (function)`: A function to call for each node, which receives `node`
  and `index` arguments.

### `container.walk(callback)`

Like `container#each`, but will also iterate child nodes as long as they are
`container` types.

```js
selectors.walk((selector, index) => {
    // all nodes
});
```

Arguments:

* `callback (function)`: A function to call for each node, which receives `node`
  and `index` arguments.

This iterator is safe to use whilst mutating `container.nodes`,
like `container#each`.

### `container.walk` proxies

The container class provides proxy methods for iterating over types of nodes,
so that it is easier to write modules that target specific selectors. Those
methods are:

* `container.walkAttributes`
* `container.walkClasses`
* `container.walkCombinators`
* `container.walkComments`
* `container.walkIds`
* `container.walkNesting`
* `container.walkPseudos`
* `container.walkTags`
* `container.walkUniversals`

### `container.split(callback)`

This method allows you to split a group of nodes by returning `true` from
a callback. It returns an array of arrays, where each inner array corresponds
to the groups that you created via the callback.

```js
// (input) => h1 h2>>h3
const list = selectors.first.split(selector => {
    return selector.type === 'combinator';
});

// (node values) => [['h1', ' '], ['h2', '>>'], ['h3']]
```

Arguments:

* `callback (function)`: A function to call for each node, which receives `node`
  as an argument.

### `container.prepend(node)` & `container.append(node)`

Add a node to the start/end of the container. Note that doing so will set
the parent property of the node to this container.

```js
const id = parser.id({value: 'search'});
selector.append(id);
```

Arguments:

* `node`: The node to add.

### `container.insertBefore(old, new)` & `container.insertAfter(old, new)`

Add a node before or after an existing node in a container:

```js
selectors.walk(selector => {
    if (selector.type !== 'class') {
        const className = parser.className({value: 'theme-name'});
        selector.parent.insertAfter(selector, className);
    }
});
```

Arguments:

* `old`: The existing node in the container.
* `new`: The new node to add before/after the existing node.

### `container.removeChild(node)`

Remove the node from the container. Note that you can also use
`node.remove()` if you would like to remove just a single node.

```js
selector.length // => 2
selector.remove(id)
selector.length // => 1;
id.parent       // undefined
```

Arguments:

* `node`: The node to remove.

### `container.removeAll()` or `container.empty()`

Remove all children from the container.

```js
selector.removeAll();
selector.length // => 0
```

## Root nodes

A root node represents a comma separated list of selectors. Indeed, all
a root's `toString()` method does is join its selector children with a ','.
Other than this, it has no special functionality and acts like a container.

### `root.trailingComma`

This will be set to `true` if the input has a trailing comma, in order to
support parsing of legacy CSS hacks.

## Selector nodes

A selector node represents a single complex selector. For example, this
selector string `h1 h2 h3, [href] > p`, is represented as two selector nodes.
It has no special functionality of its own.

## Pseudo nodes

A pseudo selector extends a container node; if it has any parameters of its
own (such as `h1:not(h2, h3)`), they will be its children. Note that the pseudo
`value` will always contain the colons preceding the pseudo identifier. This
is so that both `:before` and `::before` are properly represented in the AST.

## Attribute nodes

### `attribute.quoted`

Returns `true` if the attribute's value is wrapped in quotation marks, false if it is not.
Remains `undefined` if there is no attribute value.

```css
[href=foo] /* false */
[href='foo'] /* true */
[href="foo"] /* true */
[href] /* undefined */
```

### `attribute.qualifiedAttribute`

Returns the attribute name qualified with the namespace if one is given.

### `attribute.offsetOf(part)`

 Returns the offset of the attribute part specified relative to the
 start of the node of the output string. This is useful in raising
 error messages about a specific part of the attribute, especially
 in combination with `attribute.sourceIndex`.

 Returns `-1` if the name is invalid or the value doesn't exist in this
 attribute.

 The legal values for `part` are:

 * `"ns"` - alias for "namespace"
 * `"namespace"` - the namespace if it exists.
 * `"attribute"` - the attribute name
 * `"attributeNS"` - the start of the attribute or its namespace
 * `"operator"` - the match operator of the attribute
 * `"value"` - The value (string or identifier)
 * `"insensitive"` - the case insensitivity flag

### `attribute.raws.unquoted`

Returns the unquoted content of the attribute's value.
Remains `undefined` if there is no attribute value.

```css
[href=foo] /* foo */
[href='foo'] /* foo */
[href="foo"] /* foo */
[href] /* undefined */
```

### `attribute.spaces`

Like `node.spaces` with the `before` and `after` values containing the spaces
around the element, the parts of the attribute can also have spaces before
and after them. The for each of `attribute`, `operator`, `value` and
`insensitive` there is corresponding property of the same nam in
`node.spaces` that has an optional `before` or `after` string containing only
whitespace.

Note that corresponding values in `attributes.raws.spaces` contain values
including any comments. If set, these values will override the
`attribute.spaces` value. Take care to remove them if changing
`attribute.spaces`.

### `attribute.raws`

The raws object stores comments and other information necessary to re-render
the node exactly as it was in the source.

If a comment is embedded within the identifiers for the `namespace`, `attribute`
or `value` then a property is placed in the raws for that value containing the full source of the propery including comments.

If a comment is embedded within the space between parts of the attribute
then the raw for that space is set accordingly.

Setting an attribute's property `raws` value to be deleted.

For now, changing the spaces required also updating or removing any of the
raws values that override them.

Example: `[ /*before*/ href /* after-attr */ = /* after-operator */ te/*inside-value*/st/* wow */ /*omg*/i/*bbq*/ /*whodoesthis*/]` would parse as:

```js
{
  attribute: "href",
  operator: "=",
  value: "test",
  spaces: {
    before: '',
    after: '',
    attribute: { before: '  ', after: '  ' },
    operator: { after: '  ' },
    value: { after: ' ' },
    insensitive: { after: ' ' }
  },
  raws: {
    spaces: {
      attribute: { before: ' /*before*/ ', after: ' /* after-attr */ ' },
      operator: { after: ' /* after-operator */ ' },
      value: { after: '/* wow */ /*omg*/' },
      insensitive: { after: '/*bbq*/ /*whodoesthis*/' }
    },
    unquoted: 'test',
    value: 'te/*inside-value*/st'
  }
}
```

## `Processor`

### `ProcessorOptions`

* `lossless` - When `true`, whitespace is preserved. Defaults to `true`.
* `updateSelector` - When `true`, if any processor methods are passed a postcss
  `Rule` node instead of a string, then that Rule's selector is updated
  with the results of the processing. Defaults to `true`.

### `process|processSync(selectors, [options])`

Processes the `selectors`, returning a string from the result of processing.

Note: when the `updateSelector` option is set, the rule's selector
will be updated with the resulting string.

**Example:**

```js
const parser = require("postcss-selector-parser");
const processor = parser();

let result = processor.processSync(' .class');
console.log(result);
// =>  .class

// Asynchronous operation
let promise = processor.process(' .class').then(result => {
    console.log(result)
    // => .class
});

// To have the parser normalize whitespace values, utilize the options
result = processor.processSync('  .class  ', {lossless: false});
console.log(result);
// => .class

// For better syntax errors, pass a PostCSS Rule node.
const postcss = require('postcss');
rule = postcss.rule({selector: ' #foo    > a,  .class  '});
processor.process(rule, {lossless: false, updateSelector: true}).then(result => {
    console.log(result);
    // => #foo>a,.class
    console.log("rule:", rule.selector);
    // => rule: #foo>a,.class
})
```

Arguments:

* `selectors (string|postcss.Rule)`: Either a selector string or a PostCSS Rule
  node.
* `[options] (object)`: Process options


### `ast|astSync(selectors, [options])`

Like `process()` and `processSync()` but after
processing the `selectors` these methods return the `Root` node of the result
instead of a string.

Note: when the `updateSelector` option is set, the rule's selector
will be updated with the resulting string.

### `transform|transformSync(selectors, [options])`

Like `process()` and `processSync()` but after
processing the `selectors` these methods return the value returned by the
processor callback.

Note: when the `updateSelector` option is set, the rule's selector
will be updated with the resulting string.

### Error Handling Within Selector Processors

The root node passed to the selector processor callback
has a method `error(message, options)` that returns an
error object. This method should always be used to raise
errors relating to the syntax of selectors. The options
to this method are passed to postcss's error constructor
([documentation](http://postcss.org/api/#container-error)).

#### Async Error Example

```js
let processor = (root) => {
    return new Promise((resolve, reject) => {
        root.walkClasses((classNode) => {
            if (/^(.*)[-_]/.test(classNode.value)) {
                let msg = "classes may not have underscores or dashes in them";
                reject(root.error(msg, {
                    index: classNode.sourceIndex + RegExp.$1.length + 1,
                    word: classNode.value
                }));
            }
        });
        resolve();
    });
};

const postcss = require("postcss");
const parser = require("postcss-selector-parser");
const selectorProcessor = parser(processor);
const plugin = postcss.plugin('classValidator', (options) => {
    return (root) => {
        let promises = [];
        root.walkRules(rule => {
            promises.push(selectorProcessor.process(rule));
        });
        return Promise.all(promises);
    };
});
postcss(plugin()).process(`
.foo-bar {
  color: red;
}
`.trim(), {from: 'test.css'}).catch((e) => console.error(e.toString()));

// CssSyntaxError: classValidator: ./test.css:1:5: classes may not have underscores or dashes in them
//
// > 1 | .foo-bar {
//     |     ^
//   2 |   color: red;
//   3 | }
```

#### Synchronous Error Example

```js
let processor = (root) => {
    root.walkClasses((classNode) => {
        if (/.*[-_]/.test(classNode.value)) {
            let msg = "classes may not have underscores or dashes in them";
            throw root.error(msg, {
                index: classNode.sourceIndex,
                word: classNode.value
            });
        }
    });
};

const postcss = require("postcss");
const parser = require("postcss-selector-parser");
const selectorProcessor = parser(processor);
const plugin = postcss.plugin('classValidator', (options) => {
    return (root) => {
        root.walkRules(rule => {
            selectorProcessor.processSync(rule);
        });
    };
});
postcss(plugin()).process(`
.foo-bar {
  color: red;
}
`.trim(), {from: 'test.css'}).catch((e) => console.error(e.toString()));

// CssSyntaxError: classValidator: ./test.css:1:5: classes may not have underscores or dashes in them
//
// > 1 | .foo-bar {
//     |     ^
//   2 |   color: red;
//   3 | }
```

      Contribution(s) alone or by combination of their Contribution(s)
      with the Work to which such Contribution(s) was submitted. If You
      institute patent litigation against any entity (including a
      cross-claim or counterclaim in a lawsuit) alleging that the Work
      or a Contribution incorporated within the Work constitutes direct
      or contributory patent infringement, then any patent licenses
      granted to You under this License for that Work shall terminate
      as of the date such litigation is filed.

   4. Redistribution. You may reproduce and distribute copies of the
      Work or Derivative Works thereof in any medium, with or without
      modifications, and in Source or Object form, provided that You
      meet the following conditions:

      (a) You must give any other recipients of the Work or
          Derivative Works a copy of this License; and

      (b) You must cause any modified files to carry prominent notices
          stating that You changed the files; and

      (c) You must retain, in the Source form of any Derivative Works
          that You distribute, all copyright, patent, trademark, and
          attribution notices from the Source form of the Work,
          excluding those notices that do not pertain to any part of
          the Derivative Works; and

      (d) If the Work includes a "NOTICE" text file as part of its
          distribution, then any Derivative Works that You distribute must
          include a readable copy of the attribution notices contained
          within such NOTICE file, excluding those notices that do not
          pertain to any part of the Derivative Works, in at least one
          of the following places: within a NOTICE text file distributed
          as part of the Derivative Works; within the Source form or
          documentation, if provided along with the Derivative Works; or,
          within a display generated by the Derivative Works, if and
          wherever such third-party notices normally appear. The contents
          of the NOTICE file are for informational purposes only and
          do not modify the License. You may add Your own attribution
          notices within Derivative Works that You distribute, alongside
          or as an addendum to the NOTICE text from the Work, provided
          that such additional attribution notices cannot be construed
          as modifying the License.

      You may add Your own copyright statement to Your modifications and
      may provide additional or different license terms and conditions
      for use, reproduction, or distribution of Your modifications, or
      for any such Derivative Works as a whole, provided Your use,
      reproduction, and distribution of the Work otherwise complies with
      the conditions stated in this License.

   5. Submission of Contributions. Unless You explicitly state otherwise,
      any Contribution intentionally submitted for inclusion in the Work
      by You to the Licensor shall be under the terms and conditions of
      this License, without any additional terms or conditions.
      Notwithstanding the above, nothing herein shall supersede or modify
      the terms of any separate license agreement you may have executed
      with Licensor regarding such Contributions.

   6. Trademarks. This License does not grant permission to use the trade
      names, trademarks, service marks, or product names of the Licensor,
      except as required for reasonable and customary use in describing the
      origin of the Work and reproducing the content of the NOTICE file.

   7. Disclaimer of Warranty. Unless required by applicable law or
      agreed to in writing, Licensor provides the Work (and each
      Contributor provides its Contributions) on an "AS IS" BASIS,
      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or

      PARTICULAR PURPOSE. You are solely responsible for determining the
      appropriateness of using or redistributing the Work and assume any
      risks associated with Your exercise of permissions under this License.

   8. Limitation of Liability. In no event and under no legal theory,
      whether in tort (including negligence), contract, or otherwise,
      unless required by applicable law (such as deliberate and grossly
      negligent acts) or agreed to in writing, shall any Contributor be
      liable to You for damages, including any direct, indirect, special,
      incidental, or consequential damages of any character arising as a
      result of this License or out of the use or inability to use the
      Work (including but not limited to damages for loss of goodwill,
      work stoppage, computer failure or malfunction, or any and all
      other commercial damages or losses), even if such Contributor
      has been advised of the possibility of such damages.

   9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
      of your accepting any such warranty or additional liability.

# QRCode Terminal Edition [![Build Status][travis-ci-img]][travis-ci-url]

> Going where no QRCode has gone before.

![Basic Example][basic-example-img]

# Node Library

## Install

Can be installed with:

    $ npm install qrcode-terminal

and used:

    var qrcode = require('qrcode-terminal');

## Usage

To display some data to the terminal just call:

    qrcode.generate('This will be a QRCode, eh!');

You can even specify the error level (default is 'L'):
    
    qrcode.setErrorLevel('Q');
    qrcode.generate('This will be a QRCode with error level Q!');

If you don't want to display to the terminal but just want to string you can provide a callback:

    qrcode.generate('http://github.com', function (qrcode) {
        console.log(qrcode);
    });

If you want to display small output, provide `opts` with `small`:

    qrcode.generate('This will be a small QRCode, eh!', {small: true});

    qrcode.generate('This will be a small QRCode, eh!', {small: true}, function (qrcode) {
        console.log(qrcode)
    });

# Command-Line

## Install

    $ npm install -g qrcode-terminal

## Usage

    $ qrcode-terminal --help
    $ qrcode-terminal 'http://github.com'
    $ echo 'http://github.com' | qrcode-terminal

# Support

The [UNIX command](<http://en.wikipedia.org/wiki/Rm_(Unix)>) `rm -rf` for node
in a cross-platform implementation.

Install with `npm install rimraf`.

## Major Changes

### v4 to v5

- There is no default export anymore. Import the functions directly
  using, e.g., `import { rimrafSync } from 'rimraf'`.

### v3 to v4

- The function returns a `Promise` instead of taking a callback.
- Globbing requires the `--glob` CLI option or `glob` option property
  to be set. (Removed in 4.0 and 4.1, opt-in support added in 4.2.)
- Functions take arrays of paths, as well as a single path.
- Native implementation used by default when available, except on
  Windows, where this implementation is faster and more reliable.
- New implementation on Windows, falling back to "move then
  remove" strategy when exponential backoff for `EBUSY` fails to
  resolve the situation.
- Simplified implementation on POSIX, since the Windows
  affordances are not necessary there.
- As of 4.3, return/resolve value is boolean instead of undefined.

## API

Hybrid module, load either with `import` or `require()`.

```js
// 'rimraf' export is the one you probably want, but other
// strategies exported as well.
import { rimraf, rimrafSync, native, nativeSync } from 'rimraf'
// or
const { rimraf, rimrafSync, native, nativeSync } = require('rimraf')
```

All removal functions return a boolean indicating that all
entries were successfully removed.

The only case in which this will not return `true` is if
something was omitted from the removal via a `filter` option.

### `rimraf(f, [opts]) -> Promise`

This first parameter is a path or array of paths. The second
argument is an options object.

Options:

- `preserveRoot`: If set to boolean `false`, then allow the
  recursive removal of the root directory. Otherwise, this is
  not allowed.
- `tmp`: Windows only. Temp folder to place files and
  folders for the "move then remove" fallback. Must be on the
  same physical device as the path being deleted. Defaults to
  `os.tmpdir()` when that is on the same drive letter as the path
  being deleted, or `${drive}:\temp` if present, or `${drive}:\`
  if not.
- `maxRetries`: Windows and Native only. Maximum number of
  retry attempts in case of `EBUSY`, `EMFILE`, and `ENFILE`
  errors. Default `10` for Windows implementation, `0` for Native
  implementation.
- `backoff`: Windows only. Rate of exponential backoff for async
  removal in case of `EBUSY`, `EMFILE`, and `ENFILE` errors.
  Should be a number greater than 1. Default `1.2`
- `maxBackoff`: Windows only. Maximum total backoff time in ms to
  attempt asynchronous retries in case of `EBUSY`, `EMFILE`, and
  `ENFILE` errors. Default `200`. With the default `1.2` backoff
  rate, this results in 14 retries, with the final retry being
  delayed 33ms.
- `retryDelay`: Native only. Time to wait between retries, using
  linear backoff. Default `100`.
- `signal` Pass in an AbortSignal to cancel the directory
  removal. This is useful when removing large folder structures,
  if you'd like to limit the time spent.

  Using a `signal` option prevents the use of Node's built-in
  `fs.rm` because that implementation does not support abort
  signals.

- `glob` Boolean flag to treat path as glob pattern, or an object
  specifying [`glob` options](https://github.com/isaacs/node-glob).
- `filter` Method that returns a boolean indicating whether that
  path should be deleted. With async `rimraf` methods, this may
  return a Promise that resolves to a boolean. (Since Promises
  are truthy, returning a Promise from a sync filter is the same
  as just not filtering anything.)

  The first argument to the filter is the path string. The
  second argument is either a `Dirent` or `Stats` object for that
  path. (The first path explored will be a `Stats`, the rest
  will be `Dirent`.)

  If a filter method is provided, it will _only_ remove entries
  if the filter returns (or resolves to) a truthy value. Omitting
  a directory will still allow its children to be removed, unless
  they are also filtered out, but any parents of a filtered entry
  will not be removed, since the directory will not be empty in
  that case.

  Using a filter method prevents the use of Node's built-in
  `fs.rm` because that implementation does not support filtering.

Any other options are provided to the native Node.js `fs.rm` implementation
when that is used.

This will attempt to choose the best implementation, based on the Node.js
version and `process.platform`. To force a specific implementation, use
one of the other functions provided.

### `rimraf.sync(f, [opts])` <br> `rimraf.rimrafSync(f, [opts])`

Synchronous form of `rimraf()`

Note that, unlike many file system operations, the synchronous form will
typically be significantly _slower_ than the async form, because recursive
deletion is extremely parallelizable.

### `rimraf.native(f, [opts])`

Uses the built-in `fs.rm` implementation that Node.js provides. This is
used by default on Node.js versions greater than or equal to `14.14.0`.

### `rimraf.native.sync(f, [opts])` <br> `rimraf.nativeSync(f, [opts])`

Synchronous form of `rimraf.native`

### `rimraf.manual(f, [opts])`

Use the JavaScript implementation appropriate for your operating system.

### `rimraf.manual.sync(f, [opts])` <br> `rimraf.manualSync(f, opts)`

Synchronous form of `rimraf.manual()`

### `rimraf.windows(f, [opts])`

JavaScript implementation of file removal appropriate for Windows
platforms. Works around `unlink` and `rmdir` not being atomic
operations, and `EPERM` when deleting files with certain
permission modes.

First deletes all non-directory files within the tree, and then
removes all directories, which should ideally be empty by that
time. When an `ENOTEMPTY` is raised in the second pass, falls
back to the `rimraf.moveRemove` strategy as needed.

### `rimraf.windows.sync(path, [opts])` <br> `rimraf.windowsSync(path, [opts])`

Synchronous form of `rimraf.windows()`

### `rimraf.moveRemove(path, [opts])`

Moves all files and folders to the parent directory of `path`
with a temporary filename prior to attempting to remove them.

Note that, in cases where the operation fails, this _may_ leave
files lying around in the parent directory with names like
`.file-basename.txt.0.123412341`. Until the Windows kernel
provides a way to perform atomic `unlink` and `rmdir` operations,
this is, unfortunately, unavoidable.

To move files to a different temporary directory other than the
parent, provide `opts.tmp`. Note that this _must_ be on the same
physical device as the folder being deleted, or else the
operation will fail.

This is the slowest strategy, but most reliable on Windows
platforms. Used as a last-ditch fallback by `rimraf.windows()`.

### `rimraf.moveRemove.sync(path, [opts])` <br> `rimraf.moveRemoveSync(path, [opts])`

Synchronous form of `rimraf.moveRemove()`

### Command Line Interface

  -V --no-verbose      Be silent when deleting files, showing nothing as
                       they are removed (default)
  -i --interactive     Ask for confirmation before deleting anything
                       Not compatible with --impl=native
  -I --no-interactive  Do not ask for confirmation before deleting

  --impl=<type>        Specify the implementation to use:
                       rimraf: choose the best option (default)
                       native: the built-in implementation in Node.js
                       manual: the platform-specific JS implementation
                       posix: the Posix JS implementation
                       windows: the Windows JS implementation (falls back to
                                move-remove on ENOTEMPTY)
                       move-remove: a slow reliable Windows fallback

Implementation-specific options:
  --tmp=<path>        Temp file folder for 'move-remove' implementation
  --max-retries=<n>   maxRetries for 'native' and 'windows' implementations
  --retry-delay=<n>   retryDelay for 'native' implementation, default 100
  --backoff=<n>       Exponential backoff factor for retries (default: 1.2)

# Porting to the Buffer.from/Buffer.alloc API

<a id="overview"></a>
## Overview

- [Variant 1: Drop support for Node.js ≤ 4.4.x and 5.0.0 — 5.9.x.](#variant-1) (*recommended*)
- [Variant 2: Use a polyfill](#variant-2)
- [Variant 3: manual detection, with safeguards](#variant-3)

### Finding problematic bits of code using grep

Just run `grep -nrE '[^a-zA-Z](Slow)?Buffer\s*\(' --exclude-dir node_modules`.

It will find all the potentially unsafe places in your own code (with some considerably unlikely
exceptions).

### Finding problematic bits of code using Node.js 8

If you’re using Node.js ≥ 8.0.0 (which is recommended), Node.js exposes multiple options that help with finding the relevant pieces of code:

- `--trace-warnings` will make Node.js show a stack trace for this warning and other warnings that are printed by Node.js.
- `--trace-deprecation` does the same thing, but only for deprecation warnings.
- `--pending-deprecation` will show more types of deprecation warnings. In particular, it will show the `Buffer()` deprecation warning, even on Node.js 8.

You can set these flags using an environment variable:

```console
$ export NODE_OPTIONS='--trace-warnings --pending-deprecation'
$ cat example.js
'use strict';
const foo = new Buffer('foo');
$ node example.js
(node:7147) [DEP0005] DeprecationWarning: The Buffer() and new Buffer() constructors are not recommended for use due to security and usability concerns. Please use the new Buffer.alloc(), Buffer.allocUnsafe(), or Buffer.from() construction methods instead.
    at showFlaggedDeprecation (buffer.js:127:13)
    at new Buffer (buffer.js:148:3)
    at Object.<anonymous> (/path/to/example.js:2:13)
    [... more stack trace lines ...]
```

### Finding problematic bits of code using linters

Eslint rules [no-buffer-constructor](https://eslint.org/docs/rules/no-buffer-constructor)
or
[node/no-deprecated-api](https://github.com/mysticatea/eslint-plugin-node/blob/master/docs/rules/no-deprecated-api.md)
also find calls to deprecated `Buffer()` API. Those rules are included in some pre-sets.

There is a drawback, though, that it doesn't always
[work correctly](https://github.com/chalker/safer-buffer#why-not-safe-buffer) when `Buffer` is
overriden e.g. with a polyfill, so recommended is a combination of this and some other method
described above.

<a id="variant-1"></a>
## Variant 1: Drop support for Node.js ≤ 4.4.x and 5.0.0 — 5.9.x.

This is the recommended solution nowadays that would imply only minimal overhead.

The Node.js 5.x release line has been unsupported since July 2016, and the Node.js 4.x release line reaches its End of Life in April 2018 (→ [Schedule](https://github.com/nodejs/Release#release-schedule)). This means that these versions of Node.js will *not* receive any updates, even in case of security issues, so using these release lines should be avoided, if at all possible.

What you would do in this case is to convert all `new Buffer()` or `Buffer()` calls to use `Buffer.alloc()` or `Buffer.from()`, in the following way:

- For `new Buffer(number)`, replace it with `Buffer.alloc(number)`.
- For `new Buffer(string)` (or `new Buffer(string, encoding)`), replace it with `Buffer.from(string)` (or `Buffer.from(string, encoding)`).
- For all other combinations of arguments (these are much rarer), also replace `new Buffer(...arguments)` with `Buffer.from(...arguments)`.

Note that `Buffer.alloc()` is also _faster_ on the current Node.js versions than
`new Buffer(size).fill(0)`, which is what you would otherwise need to ensure zero-filling.

Enabling eslint rule [no-buffer-constructor](https://eslint.org/docs/rules/no-buffer-constructor)
or
[node/no-deprecated-api](https://github.com/mysticatea/eslint-plugin-node/blob/master/docs/rules/no-deprecated-api.md)
is recommended to avoid accidential unsafe Buffer API usage.

There is also a [JSCodeshift codemod](https://github.com/joyeecheung/node-dep-codemod#dep005)
for automatically migrating Buffer constructors to `Buffer.alloc()` or `Buffer.from()`.
Note that it currently only works with cases where the arguments are literals or where the
constructor is invoked with two arguments.

_If you currently support those older Node.js versions and dropping them would be a semver-major change
for you, or if you support older branches of your packages, consider using [Variant 2](#variant-2)
or [Variant 3](#variant-3) on older branches, so people using those older branches will also receive
the fix. That way, you will eradicate potential issues caused by unguarded Buffer API usage and
your users will not observe a runtime deprecation warning when running your code on Node.js 10._

<a id="variant-2"></a>
## Variant 2: Use a polyfill

Utilize [safer-buffer](https://www.npmjs.com/package/safer-buffer) as a polyfill to support older
Node.js versions.

You would take exacly the same steps as in [Variant 1](#variant-1), but with a polyfill
`const Buffer = require('safer-buffer').Buffer` in all files where you use the new `Buffer` api.

Make sure that you do not use old `new Buffer` API — in any files where the line above is added,
using old `new Buffer()` API will _throw_. It will be easy to notice that in CI, though.

Alternatively, you could use [buffer-from](https://www.npmjs.com/package/buffer-from) and/or
[buffer-alloc](https://www.npmjs.com/package/buffer-alloc) [ponyfills](https://ponyfill.com/) —
those are great, the only downsides being 4 deps in the tree and slightly more code changes to
migrate off them (as you would be using e.g. `Buffer.from` under a different name). If you need only
`Buffer.from` polyfilled — `buffer-from` alone which comes with no extra dependencies.

_Alternatively, you could use [safe-buffer](https://www.npmjs.com/package/safe-buffer) — it also
provides a polyfill, but takes a different approach which has
[it's drawbacks](https://github.com/chalker/safer-buffer#why-not-safe-buffer). It will allow you
to also use the older `new Buffer()` API in your code, though — but that's arguably a benefit, as
it is problematic, can cause issues in your code, and will start emitting runtime deprecation
warnings starting with Node.js 10._

Note that in either case, it is important that you also remove all calls to the old Buffer
API manually — just throwing in `safe-buffer` doesn't fix the problem by itself, it just provides
a polyfill for the new API. I have seen people doing that mistake.

Enabling eslint rule [no-buffer-constructor](https://eslint.org/docs/rules/no-buffer-constructor)
or
[node/no-deprecated-api](https://github.com/mysticatea/eslint-plugin-node/blob/master/docs/rules/no-deprecated-api.md)
is recommended.

_Don't forget to drop the polyfill usage once you drop support for Node.js < 4.5.0._

<a id="variant-3"></a>
## Variant 3 — manual detection, with safeguards

This is useful if you create Buffer instances in only a few places (e.g. one), or you have your own
wrapper around them.

### Buffer(0)

This special case for creating empty buffers can be safely replaced with `Buffer.concat([])`, which
returns the same result all the way down to Node.js 0.8.x.

### Buffer(notNumber)

Before:

```js
var buf = new Buffer(notNumber, encoding);
```

After:

```js
var buf;
if (Buffer.from && Buffer.from !== Uint8Array.from) {
  buf = Buffer.from(notNumber, encoding);
} else {
  if (typeof notNumber === 'number')
    throw new Error('The "size" argument must be of type number.');
  buf = new Buffer(notNumber, encoding);
}
```

`encoding` is optional.

Note that the `typeof notNumber` before `new Buffer` is required (for cases when `notNumber` argument is not
hard-coded) and _is not caused by the deprecation of Buffer constructor_ — it's exactly _why_ the
Buffer constructor is deprecated. Ecosystem packages lacking this type-check caused numereous
security issues — situations when unsanitized user input could end up in the `Buffer(arg)` create
problems ranging from DoS to leaking sensitive information to the attacker from the process memory.

When `notNumber` argument is hardcoded (e.g. literal `"abc"` or `[0,1,2]`), the `typeof` check can
be omitted.

Also note that using TypeScript does not fix this problem for you — when libs written in
`TypeScript` are used from JS, or when user input ends up there — it behaves exactly as pure JS, as
all type checks are translation-time only and are not present in the actual JS code which TS
compiles to.

### Buffer(number)

For Node.js 0.10.x (and below) support:

```js
var buf;
if (Buffer.alloc) {
  buf = Buffer.alloc(number);
} else {
  buf = new Buffer(number);
  buf.fill(0);
}
```

Otherwise (Node.js ≥ 0.12.x):

```js
const buf = Buffer.alloc ? Buffer.alloc(number) : new Buffer(number).fill(0);
```

## Regarding Buffer.allocUnsafe

Be extra cautious when using `Buffer.allocUnsafe`:
 * Don't use it if you don't have a good reason to
   * e.g. you probably won't ever see a performance difference for small buffers, in fact, those
     might be even faster with `Buffer.alloc()`,
   * if your code is not in the hot code path — you also probably won't notice a difference,
   * keep in mind that zero-filling minimizes the potential risks.
 * If you use it, make sure that you never return the buffer in a partially-filled state,
   * if you are writing to it sequentially — always truncate it to the actuall written length

Errors in handling buffers allocated with `Buffer.allocUnsafe` could result in various issues,
ranged from undefined behaviour of your code to sensitive data (user input, passwords, certs)
leaking to the remote attacker.

_Note that the same applies to `new Buffer` usage without zero-filling, depending on the Node.js
version (and lacking type checks also adds DoS to the list of potential problems)._

## FAQ

<a id="design-flaws"></a>
### What is wrong with the `Buffer` constructor?

The `Buffer` constructor could be used to create a buffer in many different ways:

- `new Buffer(42)` creates a `Buffer` of 42 bytes. Before Node.js 8, this buffer contained
  *arbitrary memory* for performance reasons, which could include anything ranging from
  program source code to passwords and encryption keys.
- `new Buffer('abc')` creates a `Buffer` that contains the UTF-8-encoded version of
  the string `'abc'`. A second argument could specify another encoding: For example,
  `new Buffer(string, 'base64')` could be used to convert a Base64 string into the original
  sequence of bytes that it represents.
- There are several other combinations of arguments.

This meant that, in code like `var buffer = new Buffer(foo);`, *it is not possible to tell
what exactly the contents of the generated buffer are* without knowing the type of `foo`.

Sometimes, the value of `foo` comes from an external source. For example, this function
could be exposed as a service on a web server, converting a UTF-8 string into its Base64 form:

```
function stringToBase64(req, res) {
  // The request body should have the format of `{ string: 'foobar' }`
  const rawBytes = new Buffer(req.body.string)
  const encoded = rawBytes.toString('base64')
  res.end({ encoded: encoded })
}
```

Note that this code does *not* validate the type of `req.body.string`:

- `req.body.string` is expected to be a string. If this is the case, all goes well.
- `req.body.string` is controlled by the client that sends the request.
- If `req.body.string` is the *number* `50`, the `rawBytes` would be 50 bytes:
  - Before Node.js 8, the content would be uninitialized
  - After Node.js 8, the content would be `50` bytes with the value `0`

Because of the missing type check, an attacker could intentionally send a number
as part of the request. Using this, they can either:

- Read uninitialized memory. This **will** leak passwords, encryption keys and other
  kinds of sensitive information. (Information leak)
- Force the program to allocate a large amount of memory. For example, when specifying
  `500000000` as the input value, each request will allocate 500MB of memory.
  This can be used to either exhaust the memory available of a program completely
  and make it crash, or slow it down significantly. (Denial of Service)

Both of these scenarios are considered serious security issues in a real-world
web server context.

when using `Buffer.from(req.body.string)` instead, passing a number will always
throw an exception instead, giving a controlled behaviour that can always be
handled by the program.

### The `Buffer()` constructor has been deprecated for a while. Is this really an issue?

Surveys of code in the `npm` ecosystem have shown that the `Buffer()` constructor is still
widely used. This includes new code, and overall usage of such code has actually been
*increasing*.

semver(1) -- The semantic versioner for npm
===========================================

## Install

```bash
npm install semver
````

## Usage

As a node module:

```js
const semver = require('semver')

semver.valid('1.2.3') // '1.2.3'
semver.valid('a.b.c') // null
semver.clean('  =v1.2.3   ') // '1.2.3'
semver.satisfies('1.2.3', '1.x || >=2.5.0 || 5.0.0 - 7.2.3') // true
semver.gt('1.2.3', '9.8.7') // false
semver.lt('1.2.3', '9.8.7') // true
semver.minVersion('>=1.0.0') // '1.0.0'
semver.valid(semver.coerce('v2')) // '2.0.0'
semver.valid(semver.coerce('42.6.7.9.3-alpha')) // '42.6.7'
```

You can also just load the module for the function that you care about if
you'd like to minimize your footprint.

```js
// load the whole API at once in a single object
const semver = require('semver')

// or just load the bits you need
// all of them listed here, just pick and choose what you want

// classes
const SemVer = require('semver/classes/semver')
const Comparator = require('semver/classes/comparator')
const Range = require('semver/classes/range')

// functions for working with versions
const semverParse = require('semver/functions/parse')
const semverValid = require('semver/functions/valid')
const semverClean = require('semver/functions/clean')
const semverInc = require('semver/functions/inc')
const semverDiff = require('semver/functions/diff')
const semverMajor = require('semver/functions/major')

const semverCompareLoose = require('semver/functions/compare-loose')
const semverCompareBuild = require('semver/functions/compare-build')
const semverSort = require('semver/functions/sort')
const semverRsort = require('semver/functions/rsort')

// low-level comparators between versions
const semverGt = require('semver/functions/gt')
const semverLt = require('semver/functions/lt')
const semverEq = require('semver/functions/eq')
const semverNeq = require('semver/functions/neq')
const semverGte = require('semver/functions/gte')
const semverLte = require('semver/functions/lte')
const semverCmp = require('semver/functions/cmp')
const semverCoerce = require('semver/functions/coerce')

// working with ranges
const semverSatisfies = require('semver/functions/satisfies')
const semverMaxSatisfying = require('semver/ranges/max-satisfying')
const semverMinSatisfying = require('semver/ranges/min-satisfying')
const semverToComparators = require('semver/ranges/to-comparators')
const semverMinVersion = require('semver/ranges/min-version')
const semverValidRange = require('semver/ranges/valid')
const semverOutside = require('semver/ranges/outside')
const semverGtr = require('semver/ranges/gtr')
const semverLtr = require('semver/ranges/ltr')
const semverIntersects = require('semver/ranges/intersects')
const semverSimplifyRange = require('semver/ranges/simplify')
const semverRangeSubset = require('semver/ranges/subset')
```

As a command-line utility:

```
$ semver -h

A JavaScript implementation of the https://semver.org/ specification
Copyright Isaac Z. Schlueter

Usage: semver [options] <version> [<version> [...]]
Prints valid versions sorted by SemVer precedence

Options:
-r --range <range>
        Print versions that match the specified range.

-i --increment [<level>]
        Increment a version by the specified level.  Level can
        be one of: major, minor, patch, premajor, preminor,
        prepatch, or prerelease.  Default level is 'patch'.
        Only one version may be specified.

--preid <identifier>
        Identifier to be used to prefix premajor, preminor,
        prepatch or prerelease version increments.

-l --loose
        Interpret versions and ranges loosely

-n <0|1>
        This is the base to be used for the prerelease identifier.

-p --include-prerelease
        Always include prerelease versions in range matching

-c --coerce
        Coerce a string into SemVer if possible
        (does not imply --loose)

--rtl
        Coerce version strings right to left

--ltr
        Coerce version strings left to right (default)

Program exits successfully if any valid version satisfies
all supplied ranges, and prints all satisfying versions.

If no satisfying versions are found, then exits failure.

Versions are printed in ascending order, so supplying
multiple versions to the utility will just sort them.
```

## Versions

A "version" is described by the `v2.0.0` specification found at
<https://semver.org/>.

A leading `"="` or `"v"` character is stripped off and ignored.

## Ranges

A `version range` is a set of `comparators` that specify versions
that satisfy the range.

A `comparator` is composed of an `operator` and a `version`.  The set
of primitive `operators` is:

* `<` Less than
* `<=` Less than or equal to
* `>` Greater than
* `>=` Greater than or equal to
* `=` Equal.  If no operator is specified, then equality is assumed,
  so this operator is optional but MAY be included.

For example, the comparator `>=1.2.7` would match the versions
`1.2.7`, `1.2.8`, `2.5.3`, and `1.3.9`, but not the versions `1.2.6`
or `1.1.0`. The comparator `>1` is equivalent to `>=2.0.0` and
would match the versions `2.0.0` and `3.1.0`, but not the versions
`1.0.1` or `1.1.0`.

Comparators can be joined by whitespace to form a `comparator set`,
which is satisfied by the **intersection** of all of the comparators
it includes.

A range is composed of one or more comparator sets, joined by `||`.  A
version matches a range if and only if every comparator in at least
one of the `||`-separated comparator sets is satisfied by the version.

For example, the range `>=1.2.7 <1.3.0` would match the versions
`1.2.7`, `1.2.8`, and `1.2.99`, but not the versions `1.2.6`, `1.3.0`,
or `1.1.0`.

The range `1.2.7 || >=1.2.9 <2.0.0` would match the versions `1.2.7`,
`1.2.9`, and `1.4.6`, but not the versions `1.2.8` or `2.0.0`.

### Prerelease Tags

If a version has a prerelease tag (for example, `1.2.3-alpha.3`) then
it will only be allowed to satisfy comparator sets if at least one
comparator with the same `[major, minor, patch]` tuple also has a
prerelease tag.

For example, the range `>1.2.3-alpha.3` would be allowed to match the
version `1.2.3-alpha.7`, but it would *not* be satisfied by
`3.4.5-alpha.9`, even though `3.4.5-alpha.9` is technically "greater
than" `1.2.3-alpha.3` according to the SemVer sort rules.  The version
range only accepts prerelease tags on the `1.2.3` version.
Version `3.4.5` *would* satisfy the range because it does not have a
prerelease flag, and `3.4.5` is greater than `1.2.3-alpha.7`.

The purpose of this behavior is twofold.  First, prerelease versions
frequently are updated very quickly, and contain many breaking changes
that are (by the author's design) not yet fit for public consumption.
Therefore, by default, they are excluded from range-matching
semantics.

Second, a user who has opted into using a prerelease version has
indicated the intent to use *that specific* set of
alpha/beta/rc versions.  By including a prerelease tag in the range,
the user is indicating that they are aware of the risk.  However, it
is still not appropriate to assume that they have opted into taking a
similar risk on the *next* set of prerelease versions.

Note that this behavior can be suppressed (treating all prerelease
versions as if they were normal versions, for range-matching)
by setting the `includePrerelease` flag on the options
object to any
[functions](https://github.com/npm/node-semver#functions) that do
range matching.

#### Prerelease Identifiers

The method `.inc` takes an additional `identifier` string argument that
will append the value of the string as a prerelease identifier:

```javascript
semver.inc('1.2.3', 'prerelease', 'beta')
// '1.2.4-beta.0'
```

command-line example:

```bash
$ semver 1.2.3 -i prerelease --preid beta
1.2.4-beta.0
```

Which then can be used to increment further:

```bash
$ semver 1.2.4-beta.0 -i prerelease
1.2.4-beta.1
```

#### Prerelease Identifier Base

The method `.inc` takes an optional parameter 'identifierBase' string
that will let you let your prerelease number as zero-based or one-based.
Set to `false` to omit the prerelease number altogether.
If you do not specify this parameter, it will default to zero-based.

```javascript
semver.inc('1.2.3', 'prerelease', 'beta', '1')
// '1.2.4-beta.1'
```

```javascript
semver.inc('1.2.3', 'prerelease', 'beta', false)
// '1.2.4-beta'
```

command-line example:

```bash
$ semver 1.2.3 -i prerelease --preid beta -n 1
1.2.4-beta.1
```

```bash
$ semver 1.2.3 -i prerelease --preid beta -n false
1.2.4-beta
```

### Advanced Range Syntax

Advanced range syntax desugars to primitive comparators in
deterministic ways.

Advanced ranges may be combined in the same way as primitive
comparators using white space or `||`.

#### Hyphen Ranges `X.Y.Z - A.B.C`

Specifies an inclusive set.

* `1.2.3 - 2.3.4` := `>=1.2.3 <=2.3.4`

If a partial version is provided as the first version in the inclusive
range, then the missing pieces are replaced with zeroes.

* `1.2 - 2.3.4` := `>=1.2.0 <=2.3.4`

If a partial version is provided as the second version in the
inclusive range, then all versions that start with the supplied parts
of the tuple are accepted, but nothing that would be greater than the
provided tuple parts.

* `1.2.3 - 2.3` := `>=1.2.3 <2.4.0-0`
* `1.2.3 - 2` := `>=1.2.3 <3.0.0-0`

#### X-Ranges `1.2.x` `1.X` `1.2.*` `*`

Any of `X`, `x`, or `*` may be used to "stand in" for one of the
numeric values in the `[major, minor, patch]` tuple.

* `*` := `>=0.0.0` (Any non-prerelease version satisfies, unless
  `includePrerelease` is specified, in which case any version at all
  satisfies)
* `1.x` := `>=1.0.0 <2.0.0-0` (Matching major version)
* `1.2.x` := `>=1.2.0 <1.3.0-0` (Matching major and minor versions)

A partial version range is treated as an X-Range, so the special
character is in fact optional.

* `""` (empty string) := `*` := `>=0.0.0`
* `1` := `1.x.x` := `>=1.0.0 <2.0.0-0`
* `1.2` := `1.2.x` := `>=1.2.0 <1.3.0-0`

#### Tilde Ranges `~1.2.3` `~1.2` `~1`

Allows patch-level changes if a minor version is specified on the
comparator.  Allows minor-level changes if not.

* `~1.2.3` := `>=1.2.3 <1.(2+1).0` := `>=1.2.3 <1.3.0-0`
* `~1.2` := `>=1.2.0 <1.(2+1).0` := `>=1.2.0 <1.3.0-0` (Same as `1.2.x`)
* `~1` := `>=1.0.0 <(1+1).0.0` := `>=1.0.0 <2.0.0-0` (Same as `1.x`)
* `~0.2.3` := `>=0.2.3 <0.(2+1).0` := `>=0.2.3 <0.3.0-0`
* `~0.2` := `>=0.2.0 <0.(2+1).0` := `>=0.2.0 <0.3.0-0` (Same as `0.2.x`)
* `~0` := `>=0.0.0 <(0+1).0.0` := `>=0.0.0 <1.0.0-0` (Same as `0.x`)
* `~1.2.3-beta.2` := `>=1.2.3-beta.2 <1.3.0-0` Note that prereleases in
  the `1.2.3` version will be allowed, if they are greater than or
  equal to `beta.2`.  So, `1.2.3-beta.4` would be allowed, but
  `1.2.4-beta.2` would not, because it is a prerelease of a
  different `[major, minor, patch]` tuple.

#### Caret Ranges `^1.2.3` `^0.2.5` `^0.0.4`

Allows changes that do not modify the left-most non-zero element in the
`[major, minor, patch]` tuple.  In other words, this allows patch and
minor updates for versions `1.0.0` and above, patch updates for
versions `0.X >=0.1.0`, and *no* updates for versions `0.0.X`.

Many authors treat a `0.x` version as if the `x` were the major
"breaking-change" indicator.

Caret ranges are ideal when an author may make breaking changes
between `0.2.4` and `0.3.0` releases, which is a common practice.
However, it presumes that there will *not* be breaking changes between
`0.2.4` and `0.2.5`.  It allows for changes that are presumed to be
additive (but non-breaking), according to commonly observed practices.

* `^1.2.3` := `>=1.2.3 <2.0.0-0`
* `^0.2.3` := `>=0.2.3 <0.3.0-0`
* `^0.0.3` := `>=0.0.3 <0.0.4-0`
* `^1.2.3-beta.2` := `>=1.2.3-beta.2 <2.0.0-0` Note that prereleases in
  the `1.2.3` version will be allowed, if they are greater than or
  equal to `beta.2`.  So, `1.2.3-beta.4` would be allowed, but
  `1.2.4-beta.2` would not, because it is a prerelease of a
  different `[major, minor, patch]` tuple.
* `^0.0.3-beta` := `>=0.0.3-beta <0.0.4-0`  Note that prereleases in the
  `0.0.3` version *only* will be allowed, if they are greater than or
  equal to `beta`.  So, `0.0.3-pr.2` would be allowed.

When parsing caret ranges, a missing `patch` value desugars to the
number `0`, but will allow flexibility within that value, even if the
major and minor versions are both `0`.

* `^1.2.x` := `>=1.2.0 <2.0.0-0`
* `^0.0.x` := `>=0.0.0 <0.1.0-0`
* `^0.0` := `>=0.0.0 <0.1.0-0`

A missing `minor` and `patch` values will desugar to zero, but also
allow flexibility within those values, even if the major version is
zero.

* `^1.x` := `>=1.0.0 <2.0.0-0`
* `^0.x` := `>=0.0.0 <1.0.0-0`

### Range Grammar

Putting all this together, here is a Backus-Naur grammar for ranges,
for the benefit of parser authors:

```bnf
range-set  ::= range ( logical-or range ) *
logical-or ::= ( ' ' ) * '||' ( ' ' ) *
range      ::= hyphen | simple ( ' ' simple ) * | ''
hyphen     ::= partial ' - ' partial
simple     ::= primitive | partial | tilde | caret
primitive  ::= ( '<' | '>' | '>=' | '<=' | '=' ) partial
partial    ::= xr ( '.' xr ( '.' xr qualifier ? )? )?
xr         ::= 'x' | 'X' | '*' | nr
nr         ::= '0' | ['1'-'9'] ( ['0'-'9'] ) *
tilde      ::= '~' partial
caret      ::= '^' partial
qualifier  ::= ( '-' pre )? ( '+' build )?
pre        ::= parts
build      ::= parts
parts      ::= part ( '.' part ) *
part       ::= nr | [-0-9A-Za-z]+
```

## Functions

All methods and classes take a final `options` object argument.  All
options in this object are `false` by default.  The options supported
are:

- `loose`: Be more forgiving about not-quite-valid semver strings.
  (Any resulting output will always be 100% strict compliant, of
  course.)  For backwards compatibility reasons, if the `options`
  argument is a boolean value instead of an object, it is interpreted
  to be the `loose` param.
- `includePrerelease`: Set to suppress the [default
  behavior](https://github.com/npm/node-semver#prerelease-tags) of
  excluding prerelease tagged versions from ranges unless they are
  explicitly opted into.

Strict-mode Comparators and Ranges will be strict about the SemVer
strings that they parse.

* `valid(v)`: Return the parsed version, or null if it's not valid.
* `inc(v, release, options, identifier, identifierBase)`: 
  Return the version incremented by the release
  type (`major`, `premajor`, `minor`, `preminor`, `patch`,
  `prepatch`, or `prerelease`), or null if it's not valid
  * `premajor` in one call will bump the version up to the next major
    version and down to a prerelease of that major version.
    `preminor`, and `prepatch` work the same way.
  * If called from a non-prerelease version, `prerelease` will work the
    same as `prepatch`. It increments the patch version and then makes a
    prerelease. If the input version is already a prerelease it simply
    increments it.
  * `identifier` can be used to prefix `premajor`, `preminor`,
    `prepatch`, or `prerelease` version increments. `identifierBase`
    is the base to be used for the `prerelease` identifier.
* `prerelease(v)`: Returns an array of prerelease components, or null
  if none exist. Example: `prerelease('1.2.3-alpha.1') -> ['alpha', 1]`
* `major(v)`: Return the major version number.
* `minor(v)`: Return the minor version number.
* `patch(v)`: Return the patch version number.
* `intersects(r1, r2, loose)`: Return true if the two supplied ranges
  or comparators intersect.
* `parse(v)`: Attempt to parse a string as a semantic version, returning either
  a `SemVer` object or `null`.

### Comparison

* `gt(v1, v2)`: `v1 > v2`
* `gte(v1, v2)`: `v1 >= v2`
* `lt(v1, v2)`: `v1 < v2`
* `lte(v1, v2)`: `v1 <= v2`
* `eq(v1, v2)`: `v1 == v2` This is true if they're logically equivalent,
  even if they're not the same string.  You already know how to
  compare strings.
* `neq(v1, v2)`: `v1 != v2` The opposite of `eq`.
* `cmp(v1, comparator, v2)`: Pass in a comparison string, and it'll call
  the corresponding function above.  `"==="` and `"!=="` do simple
  string comparison, but are included for completeness.  Throws if an
  invalid comparison string is provided.
* `compare(v1, v2)`: Return `0` if `v1 == v2`, or `1` if `v1` is greater, or `-1` if
  `v2` is greater.  Sorts in ascending order if passed to `Array.sort()`.
* `rcompare(v1, v2)`: The reverse of `compare`.  Sorts an array of versions
  in descending order when passed to `Array.sort()`.
* `compareBuild(v1, v2)`: The same as `compare` but considers `build` when two versions
  are equal.  Sorts in ascending order if passed to `Array.sort()`.
* `compareLoose(v1, v2)`: Short for `compare(v1, v2, { loose: true })`.
* `diff(v1, v2)`: Returns the difference between two versions by the release type
  (`major`, `premajor`, `minor`, `preminor`, `patch`, `prepatch`, or `prerelease`),
  or null if the versions are the same.

### Sorting

* `sort(versions)`: Returns a sorted array of versions based on the `compareBuild` 
  function.
* `rsort(versions)`: The reverse of `sort`. Returns an array of versions based on
  the `compareBuild` function in descending order.

### Comparators

* `intersects(comparator)`: Return true if the comparators intersect

### Ranges

* `validRange(range)`: Return the valid range or null if it's not valid
* `satisfies(version, range)`: Return true if the version satisfies the
  range.
* `maxSatisfying(versions, range)`: Return the highest version in the list
  that satisfies the range, or `null` if none of them do.
* `minSatisfying(versions, range)`: Return the lowest version in the list
  that satisfies the range, or `null` if none of them do.
* `minVersion(range)`: Return the lowest version that can match
  the given range.
* `gtr(version, range)`: Return `true` if the version is greater than all the
  versions possible in the range.
* `ltr(version, range)`: Return `true` if the version is less than all the
  versions possible in the range.
* `outside(version, range, hilo)`: Return true if the version is outside
  the bounds of the range in either the high or low direction.  The
  `hilo` argument must be either the string `'>'` or `'<'`.  (This is
  the function called by `gtr` and `ltr`.)
* `intersects(range)`: Return true if any of the range comparators intersect.
* `simplifyRange(versions, range)`: Return a "simplified" range that
  matches the same items in the `versions` list as the range specified.  Note
  that it does *not* guarantee that it would match the same versions in all
  cases, only for the set of versions provided.  This is useful when
  generating ranges by joining together multiple versions with `||`
  programmatically, to provide the user with something a bit more
  ergonomic.  If the provided range is shorter in string-length than the
  generated range, then that is returned.
* `subset(subRange, superRange)`: Return `true` if the `subRange` range is
  entirely contained by the `superRange` range.

Note that, since ranges may be non-contiguous, a version might not be
greater than a range, less than a range, *or* satisfy a range!  For
example, the range `1.2 <1.2.9 || >2.0.0` would have a hole from `1.2.9`
until `2.0.0`, so version `1.2.10` would not be greater than the
range (because `2.0.1` satisfies, which is higher), nor less than the
range (since `1.2.8` satisfies, which is lower), and it also does not
satisfy the range.

If you want to know if a version satisfies or does not satisfy a
range, use the `satisfies(version, range)` function.

### Coercion

* `coerce(version, options)`: Coerces a string to semver if possible

This aims to provide a very forgiving translation of a non-semver string to
semver. It looks for the first digit in a string and consumes all
remaining characters which satisfy at least a partial semver (e.g., `1`,
`1.2`, `1.2.3`) up to the max permitted length (256 characters).  Longer
versions are simply truncated (`4.6.3.9.2-alpha2` becomes `4.6.3`).  All
surrounding text is simply ignored (`v3.4 replaces v3.3.1` becomes
`3.4.0`).  Only text which lacks digits will fail coercion (`version one`
is not valid).  The maximum length for any semver component considered for
coercion is 16 characters; longer components will be ignored
(`10000000000000000.4.7.4` becomes `4.7.4`).  The maximum value for any
semver component is `Number.MAX_SAFE_INTEGER || (2**53 - 1)`; higher value
components are invalid (`9999999999999999.4.7.4` is likely invalid).

If the `options.rtl` flag is set, then `coerce` will return the right-most
coercible tuple that does not share an ending index with a longer coercible
tuple.  For example, `1.2.3.4` will return `2.3.4` in rtl mode, not
`4.0.0`.  `1.2.3/4` will return `4.0.0`, because the `4` is not a part of
any other overlapping SemVer tuple.

If the `options.includePrerelease` flag is set, then the `coerce` result will contain
prerelease and build parts of a version.  For example, `1.2.3.4-rc.1+rev.2`
will preserve prerelease `rc.1` and build `rev.2` in the result.

### Clean

* `clean(version)`: Clean a string to be a valid semver if possible

This will return a cleaned and trimmed semver version. If the provided
version is not valid a null will be returned. This does not work for
ranges.

ex.
* `s.clean(' = v 2.1.5foo')`: `null`
* `s.clean(' = v 2.1.5foo', { loose: true })`: `'2.1.5-foo'`
* `s.clean(' = v 2.1.5-foo')`: `null`
* `s.clean(' = v 2.1.5-foo', { loose: true })`: `'2.1.5-foo'`
* `s.clean('=v2.1.5')`: `'2.1.5'`
* `s.clean('  =v2.1.5')`: `'2.1.5'`
* `s.clean('      2.1.5   ')`: `'2.1.5'`
* `s.clean('~1.0.0')`: `null`

## Constants

As a convenience, helper constants are exported to provide information about what `node-semver` supports:

### `RELEASE_TYPES`

- major
- premajor
- minor
- preminor
- patch
- prepatch
- prerelease

```
const semver = require('semver');

if (semver.RELEASE_TYPES.includes(arbitraryUserInput)) {
  console.log('This is a valid release type!');
} else {
  console.warn('This is NOT a valid release type!');
}
```

### `SEMVER_SPEC_VERSION`

2.0.0

```
const semver = require('semver');

console.log('We are currently using the semver specification version:', semver.SEMVER_SPEC_VERSION);
```

        Coerce version strings left to right (default)

-n <base>
        Base number to be used for the prerelease identifier.
        Can be either 0 or 1, or false to omit the number altogether.
        Defaults to 0.

Program exits successfully if any valid version satisfies
all supplied ranges, and prints all satisfying versions.

If no satisfying versions are found, then exits failure.

Versions are printed in ascending order, so supplying
multiple versions to the utility will just sort them.`)

   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION

   1. Definitions.

      "License" shall mean the terms and conditions for use, reproduction,
      and distribution as defined by Sections 1 through 9 of this document.

      "Licensor" shall mean the copyright owner or entity authorized by
      the copyright owner that is granting the License.

      "Legal Entity" shall mean the union of the acting entity and all
      other entities that control, are controlled by, or are under common
      control with that entity. For the purposes of this definition,
      "control" means (i) the power, direct or indirect, to cause the
      direction or management of such entity, whether by contract or
      otherwise, or (ii) ownership of fifty percent (50%) or more of the
      outstanding shares, or (iii) beneficial ownership of such entity.

      "You" (or "Your") shall mean an individual or Legal Entity
      exercising permissions granted by this License.

      "Source" form shall mean the preferred form for making modifications,
      including but not limited to software source code, documentation
      source, and configuration files.

      "Object" form shall mean any form resulting from mechanical
      transformation or translation of a Source form, including but
      not limited to compiled object code, generated documentation,
      and conversions to other media types.

      "Work" shall mean the work of authorship, whether in Source or
      Object form, made available under the License, as indicated by a
      copyright notice that is included in or attached to the work
      (an example is provided in the Appendix below).

      "Derivative Works" shall mean any work, whether in Source or Object
      form, that is based on (or derived from) the Work and for which the
      editorial revisions, annotations, elaborations, or other modifications
      represent, as a whole, an original work of authorship. For the purposes
      of this License, Derivative Works shall not include works that remain
      separable from, or merely link (or bind by name) to the interfaces of,
      the Work and Derivative Works thereof.

      "Contribution" shall mean any work of authorship, including
      the original version of the Work and any modifications or additions
      to that Work or Derivative Works thereof, that is intentionally
      submitted to Licensor for inclusion in the Work by the copyright owner
      or by an individual or Legal Entity authorized to submit on behalf of
      the copyright owner. For the purposes of this definition, "submitted"
      means any form of electronic, verbal, or written communication sent
      to the Licensor or its representatives, including but not limited to
      communication on electronic mailing lists, source code control systems,
      and issue tracking systems that are managed by, or on behalf of, the
      Licensor for the purpose of discussing and improving the Work, but
      excluding communication that is conspicuously marked or otherwise
      designated in writing by the copyright owner as "Not a Contribution."

      "Contributor" shall mean Licensor and any individual or Legal Entity
      on behalf of whom a Contribution has been received by Licensor and
      subsequently incorporated within the Work.

   2. Grant of Copyright License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      copyright license to reproduce, prepare Derivative Works of,
      publicly display, publicly perform, sublicense, and distribute the
      Work and such Derivative Works in Source or Object form.

   3. Grant of Patent License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      (except as stated in this section) patent license to make, have made,
      use, offer to sell, sell, import, and otherwise transfer the Work,
      where such license applies only to those patent claims licensable
      by such Contributor that are necessarily infringed by their
      Contribution(s) alone or by combination of their Contribution(s)
      with the Work to which such Contribution(s) was submitted. If You
      institute patent litigation against any entity (including a
      cross-claim or counterclaim in a lawsuit) alleging that the Work
      or a Contribution incorporated within the Work constitutes direct
      or contributory patent infringement, then any patent licenses
      granted to You under this License for that Work shall terminate
      as of the date such litigation is filed.

   4. Redistribution. You may reproduce and distribute copies of the
      Work or Derivative Works thereof in any medium, with or without
      modifications, and in Source or Object form, provided that You
      meet the following conditions:

      (a) You must give any other recipients of the Work or
          Derivative Works a copy of this License; and

      (b) You must cause any modified files to carry prominent notices
          stating that You changed the files; and

      (c) You must retain, in the Source form of any Derivative Works
          that You distribute, all copyright, patent, trademark, and
          attribution notices from the Source form of the Work,
          excluding those notices that do not pertain to any part of
          the Derivative Works; and

      (d) If the Work includes a "NOTICE" text file as part of its
          distribution, then any Derivative Works that You distribute must
          include a readable copy of the attribution notices contained
          within such NOTICE file, excluding those notices that do not
          pertain to any part of the Derivative Works, in at least one
          of the following places: within a NOTICE text file distributed
          as part of the Derivative Works; within the Source form or
          documentation, if provided along with the Derivative Works; or,
          within a display generated by the Derivative Works, if and
          wherever such third-party notices normally appear. The contents
          of the NOTICE file are for informational purposes only and
          do not modify the License. You may add Your own attribution
          notices within Derivative Works that You distribute, alongside
          or as an addendum to the NOTICE text from the Work, provided
          that such additional attribution notices cannot be construed
          as modifying the License.

      You may add Your own copyright statement to Your modifications and
      may provide additional or different license terms and conditions
      for use, reproduction, or distribution of Your modifications, or
      for any such Derivative Works as a whole, provided Your use,
      reproduction, and distribution of the Work otherwise complies with
      the conditions stated in this License.

   5. Submission of Contributions. Unless You explicitly state otherwise,
      any Contribution intentionally submitted for inclusion in the Work
      by You to the Licensor shall be under the terms and conditions of
      this License, without any additional terms or conditions.
      Notwithstanding the above, nothing herein shall supersede or modify
      the terms of any separate license agreement you may have executed
      with Licensor regarding such Contributions.

   6. Trademarks. This License does not grant permission to use the trade
      names, trademarks, service marks, or product names of the Licensor,
      except as required for reasonable and customary use in describing the
      origin of the Work and reproducing the content of the NOTICE file.

   7. Disclaimer of Warranty. Unless required by applicable law or
      agreed to in writing, Licensor provides the Work (and each
      Contributor provides its Contributions) on an "AS IS" BASIS,
      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
      implied, including, without limitation, any warranties or conditions
      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
      PARTICULAR PURPOSE. You are solely responsible for determining the
      appropriateness of using or redistributing the Work and assume any
      risks associated with Your exercise of permissions under this License.

   8. Limitation of Liability. In no event and under no legal theory,
      whether in tort (including negligence), contract, or otherwise,
      unless required by applicable law (such as deliberate and grossly
      negligent acts) or agreed to in writing, shall any Contributor be
      liable to You for damages, including any direct, indirect, special,
      incidental, or consequential damages of any character arising as a
      result of this License or out of the use or inability to use the
      Work (including but not limited to damages for loss of goodwill,
      work stoppage, computer failure or malfunction, or any and all
      other commercial damages or losses), even if such Contributor
      has been advised of the possibility of such damages.

   9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
      of your accepting any such warranty or additional liability.

   END OF TERMS AND CONDITIONS

   APPENDIX: How to apply the Apache License to your work.

      To apply the Apache License to your work, attach the following
      boilerplate notice, with the fields enclosed by brackets "[]"
      replaced with your own identifying information. (Don't include
      the brackets!)  The text should be enclosed in the appropriate
      comment syntax for the file format. We also recommend that a
      file or class name and description of purpose be included on the
      same "printed page" as the copyright notice for easier
      identification within third-party archives.

## Example for SOCKS 'associate' command

The associate command tells the SOCKS proxy server to establish a UDP relay. The server binds to a new UDP port and communicates the newly opened port back to the origin client. From here, any SOCKS UDP frame packets sent to this special UDP port on the Proxy server will be forwarded to the desired destination, and any responses will be forwarded back to the origin client (you).

This can be used for things such as DNS queries, and other UDP communicates.

**Connection Steps**

1. Client -(associate)-> Proxy (Tells the proxy to create a UDP relay and bind on a new port)
2. Client <-(port)- Proxy (Tells the origin client which port it opened and is accepting UDP frame packets on)

At this point the proxy is accepting UDP frames on the specified port.

3. Client --(udp frame) -> Proxy -> Destination (The origin client sends a UDP frame to the proxy on the UDP port, and the proxy then forwards it to the destination specified in the UDP frame.)
4. Client <--(udp frame) <-- Proxy <-- Destination (The destination client responds to the udp packet sent in #3)

## Usage

The 'associate' command can only be used by creating a new SocksClient instance and listening for the 'established' event.

**Note:** UDP packets relayed through the proxy servers are encompassed in a special Socks UDP frame format. SocksClient.createUDPFrame() and SocksClient.parseUDPFrame() create and parse these special UDP packets.

```typescript
const dgram = require('dgram');
const SocksClient = require('socks').SocksClient;

// Create a local UDP socket for sending/receiving packets to/from the proxy.
const udpSocket = dgram.createSocket('udp4');
udpSocket.bind();

// Listen for incoming UDP packets from the proxy server.
udpSocket.on('message', (message, rinfo) => {
  console.log(SocksClient.parseUDPFrame(message));
  /*
  { frameNumber: 0,
    remoteHost: { host: '8.8.8.8', port: 53 }, // The remote host that replied with a UDP packet
    data: <Buffer 74 65 73 74 0a> // The data
  }
  */
});

const options = {
  proxy: {
    host: '104.131.124.203',
    port: 1081,
    type: 5
  },

  // This should be the ip and port of the expected client that will be sending UDP frames to the newly opened UDP port on the server.
  // Most SOCKS servers accept 0.0.0.0 as a wildcard address to accept UDP frames from any source.
  destination: {
    host: '0.0.0.0',
    port: 0
  },

  command: 'associate'
};

const client = new SocksClient(options);

// This event is fired when the SOCKS server has started listening on a new UDP port for UDP relaying.
client.on('established', info => {
  console.log(info);
  /*
  {
    socket: <Socket ...>,
    remoteHost: { // This is the remote port on the SOCKS proxy server to send UDP frame packets to.
      host: '104.131.124.203',
      port: 58232
    }
  }
  */

  // Send a udp frame to 8.8.8.8 on port 53 through the proxy.
  const packet = SocksClient.createUDPFrame({
    remoteHost: { host: '8.8.8.8', port: 53 },
    data: Buffer.from('hello') // A DNS lookup in the real world.
  });

  // Send packet.
  udpSocket.send(packet, info.remoteHost.port, info.remoteHost.host);
});

// SOCKS proxy failed to bind.
client.on('error', () => {
  // Handle errors
});
```
# socks examples

## Example for SOCKS 'bind' command

The bind command tells the SOCKS proxy server to bind and listen on a new TCP port for an incoming connection. It communicates the newly opened port back to the origin client. Once a incoming connection is accepted by the SOCKS proxy server it then communicates the remote host that connected to the SOCKS proxy back through the same initial connection via the origin client.

This can be used for things such as FTP clients which require incoming TCP connections, etc.

**Connection Steps**

1. Client -(bind)-> Proxy    (Tells the proxy to bind to a new port)
2. Client <-(port)- Proxy    (Tells the origin client which port it opened)
3. Client2 --> Proxy    (Other client connects to the proxy on this port)
4. Client <--(client2's host info)  (Proxy tells the origin client who connected to it)
5. Original connection to the proxy is now a full TCP stream between client (you) and client2.
6. Client <--> Proxy <--> Client2


## Usage

The 'bind' command can only be used by creating a new SocksClient instance and listening for 'bound' and 'established' events.


```typescript
const SocksClient = require('socks').SocksClient;

const options = {
  proxy: {
    host: '104.131.124.203',
    port: 1081,
    type: 5
  },

  // This should be the ip and port of the expected client that will connect to the SOCKS proxy server on the newly bound port.
  // Most SOCKS servers accept 0.0.0.0 as a wildcard address to accept any client.
  destination: {
    host: '0.0.0.0',
    port: 0
  },

  command: 'bind'
};

const client = new SocksClient(options);

// This event is fired when the SOCKS server has started listening on a new port for incoming connections.
client.on('bound', (info) => {
  console.log(info);
  /*
  {
    socket: <Socket ...>,
    remoteHost: { // This is the remote ip and port of the SOCKS proxy that is now accepting incoming connections.
      host: '104.131.124.203',
      port: 49928
    }
  }
  */
});

// This event is fired when the SOCKS server has accepted an incoming connection on the newly bound port.
client.on('established', (info) => {
  console.log(info);
  /*
  {
    socket: <Socket ...>,
    remoteHost: { // This is the remote ip and port that connected to the SOCKS proxy on the newly bound port.
      host: '1.2.3.4',
      port: 58232
    }
  }
  */

  // At this point info.socket is a regular net.Socket TCP connection between client and client2 (1.2.3.4) (the client which connected to the proxy on the newly bound port.)

  console.log(info.socket);
  // <Socket ...>  (this is a raw net.Socket that is established to the destination host through the given proxy servers)
});

// SOCKS proxy failed to bind.
client.on('error', () => {
  // Handle errors
});
```# socks examples

## Example for SOCKS 'connect' command

The connect command is the most common use-case for a SOCKS proxy. This establishes a direct connection to a destination host through a proxy server. The destination host only has knowledge of the proxy server connecting to it and does not know about the origin client (you).

**Origin Client (you) <-> Proxy Server <-> Destination Server**

In this example, we are connecting to a web server on port 80, and sending a very basic HTTP request to receive a response. It's worth noting that there are many socks-http-agents that can be used with the node http module (and libraries such as request.js) to make this easier. This HTTP request is used as a simple example.

The 'connect' command can be used via the SocksClient.createConnection() factory function as well as by creating a SocksClient instance and using event handlers.

### Using createConnection with async/await

Since SocksClient.createConnection returns a Promise, we can easily use async/await for flow control.

```typescript
const SocksClient = require('socks').SocksClient;

const options  = {
  proxy: {
    host: '104.131.124.203',
    port: 1081,
    type: 5
  },

  destination: {
    host: 'ip-api.com', // host names are supported with SOCKS v4a and SOCKS v5.
    port: 80
  },

  command: 'connect'
};

async function start() {
  try {
    const info = await SocksClient.createConnection(options);

    console.log(info.socket);
    // <Socket ...>  (this is a raw net.Socket that is established to the destination host through the given proxy servers)

    info.socket.write('GET /json HTTP/1.1\nHost: ip-api.com\n\n');
    info.socket.on('data', (data) => {
      console.log(data.toString()); // ip-api.com sees that the last proxy (104.131.124.203) is connected to it and not the origin client (you).

  } catch (err) {

}

start();
```

### Using createConnection with Promises

```typescript
const SocksClient = require('socks').SocksClient;

const options  = {
  proxy: {
    ipaddress: '104.131.124.203',
    port: 1081,
    type: 5
  },

  destination: {
    host: 'ip-api.com', // host names are supported with SOCKS v4a and SOCKS v5.
    port: 80
  },

  command: 'connect'
};

SocksClient.createConnection(options)
.then(info => {
  console.log(info.socket);
  // <Socket ...>  (this is a raw net.Socket that is established to the destination host through the given proxy servers)

  info.socket.write('GET /json HTTP/1.1\nHost: ip-api.com\n\n');
  info.socket.on('data', (data) => {
    console.log(data.toString()); // ip-api.com sees that the last proxy (104.131.124.203) is connected to it and not the origin client (you).

        "zip":"07014"
      }
    */
})
.catch(err => {
  // handle errors
});
```

### Using createConnection with callbacks

SocksClient.createConnection() optionally accepts a callback function as a second parameter.

**Note:** If a callback function is provided, a Promise is still returned from the function, but the promise will always resolve regardless of if there was en error. (tldr: Do not mix callbacks and Promises).

```typescript
const SocksClient = require('socks').SocksClient;

const options  = {
  proxy: {
    ipaddress: '104.131.124.203',
    port: 1081,
    type: 5
  },

  destination: {
    host: 'ip-api.com', // host names are supported with SOCKS v4a and SOCKS v5.
    port: 80
  },

  command: 'connect'
};

SocksClient.createConnection(options, (err, info) => {
  if (err) {
    // handle errors
  } else {
    console.log(info.socket);
    // <Socket ...>  (this is a raw net.Socket that is established to the destination host through the given proxy servers)

    info.socket.write('GET /json HTTP/1.1\nHost: ip-api.com\n\n');
    info.socket.on('data', (data) => {
      console.log(data.toString()); // ip-api.com sees that the last proxy (104.131.124.203) is connected to it and not the origin client (you).
      /*
        HTTP/1.1 200 OK
        Access-Control-Allow-Origin: *
        Content-Type: application/json; charset=utf-8
        Date: Sun, 24 Dec 2017 03:47:51 GMT
        Content-Length: 300

        {
          "as":"AS14061 Digital Ocean, Inc.",
          "city":"Clifton",
          "country":"United States",
          "countryCode":"US",
          "isp":"Digital Ocean",
          "lat":40.8326,
          "lon":-74.1307,
          "org":"Digital Ocean",
          "query":"104.131.124.203",
          "region":"NJ",
          "regionName":"New Jersey",
          "status":"success",
          "timezone":"America/New_York",
          "zip":"07014"
        }
      */
  }
})
```

### Using event handlers

SocksClient also supports instance creation of a SocksClient. This allows for event based flow control.

```typescript
const SocksClient = require('socks').SocksClient;

const options  = {
  proxy: {
    ipaddress: '104.131.124.203',
    port: 1081,
    type: 5
  },

  destination: {
    host: 'ip-api.com', // host names are supported with SOCKS v4a and SOCKS v5.
    port: 80
  },

  command: 'connect'
};

const client = new SocksClient(options);

client.on('established', (info) => {
  console.log(info.socket);
  // <Socket ...>  (this is a raw net.Socket that is established to the destination host through the given proxy servers)

  info.socket.write('GET /json HTTP/1.1\nHost: ip-api.com\n\n');
  info.socket.on('data', (data) => {
    console.log(data.toString()); // ip-api.com sees that the last proxy (104.131.124.203) is connected to it and not the origin client (you).
    /*
      HTTP/1.1 200 OK
      Access-Control-Allow-Origin: *
      Content-Type: application/json; charset=utf-8
      Date: Sun, 24 Dec 2017 03:47:51 GMT
      Content-Length: 300

      {
        "as":"AS14061 Digital Ocean, Inc.",
        "city":"Clifton",
        "country":"United States",
        "countryCode":"US",
        "isp":"Digital Ocean",
        "lat":40.8326,
        "lon":-74.1307,
        "org":"Digital Ocean",
        "query":"104.131.124.203",
        "region":"NJ",
        "regionName":"New Jersey",
        "status":"success",
        "timezone":"America/New_York",
        "zip":"07014"
      }
    */
});

// Failed to establish proxy connection to destination.

### Using createConnection with Promises

```typescript
import { SocksClient, SocksClientOptions } from 'socks';

const options: SocksClientOptions = {
  proxy: {
    ipaddress: '104.131.124.203',
    port: 1081,
    type: 5
  },

  destination: {
    host: 'ip-api.com', // host names are supported with SOCKS v4a and SOCKS v5.
    port: 80
  },

  command: 'connect'
};

SocksClient.createConnection(options)
.then(info => {
  console.log(info.socket);
  // <Socket ...>  (this is a raw net.Socket that is established to the destination host through the given proxy servers)

  info.socket.write('GET /json HTTP/1.1\nHost: ip-api.com\n\n');
  info.socket.on('data', (data) => {
    console.log(data.toString()); // ip-api.com sees that the last proxy (104.131.124.203) is connected to it and not the origin client (you).

        "city":"Clifton",

        "zip":"07014"
      }
    */
  });
})
.catch(err => {
  // handle errors
});
```

### Using createConnection with callbacks

SocksClient.createConnection() optionally accepts a callback function as a second parameter.

**Note:** If a callback function is provided, a Promise is still returned from the function, but the promise will always resolve regardless of if there was en error. (tldr: Do not mix callbacks and Promises).

```typescript
import { SocksClient, SocksClientOptions } from 'socks';

const options: SocksClientOptions = {
  proxy: {
    ipaddress: '104.131.124.203',
    port: 1081,
    type: 5
  },

  destination: {
    host: 'ip-api.com', // host names are supported with SOCKS v4a and SOCKS v5.
    port: 80
  },

  command: 'connect'
};

SocksClient.createConnection(options, (err, info) => {
  if (err) {
    // handle errors
  } else {
    console.log(info.socket);
    // <Socket ...>  (this is a raw net.Socket that is established to the destination host through the given proxy servers)

    info.socket.write('GET /json HTTP/1.1\nHost: ip-api.com\n\n');
    info.socket.on('data', (data) => {
      console.log(data.toString()); // ip-api.com sees that the last proxy (104.131.124.203) is connected to it and not the origin client (you).
      /*
        HTTP/1.1 200 OK
        Access-Control-Allow-Origin: *
        Content-Type: application/json; charset=utf-8
        Date: Sun, 24 Dec 2017 03:47:51 GMT
        Content-Length: 300

        {
          "as":"AS14061 Digital Ocean, Inc.",
          "city":"Clifton",
          "country":"United States",
          "countryCode":"US",
          "isp":"Digital Ocean",
          "lat":40.8326,
          "lon":-74.1307,
          "org":"Digital Ocean",
          "query":"104.131.124.203",
          "region":"NJ",

          "zip":"07014"
        }
      */
    });
  }
})
```

### Using event handlers

SocksClient also supports instance creation of a SocksClient. This allows for event based flow control.

```typescript
import { SocksClient, SocksClientOptions } from 'socks';

const options: SocksClientOptions = {
  proxy: {
    ipaddress: '104.131.124.203',
    port: 1081,
    type: 5
  },

  destination: {
    host: 'ip-api.com', // host names are supported with SOCKS v4a and SOCKS v5.
    port: 80
  },

  command: 'connect'
};

const client = new SocksClient(options);

client.on('established', (info) => {
  console.log(info.socket);
  // <Socket ...>  (this is a raw net.Socket that is established to the destination host through the given proxy servers)

  info.socket.write('GET /json HTTP/1.1\nHost: ip-api.com\n\n');
  info.socket.on('data', (data) => {
    console.log(data.toString()); // ip-api.com sees that the last proxy (104.131.124.203) is connected to it and not the origin client (you).
    /*
      HTTP/1.1 200 OK
      Access-Control-Allow-Origin: *
      Content-Type: application/json; charset=utf-8
      Date: Sun, 24 Dec 2017 03:47:51 GMT
      Content-Length: 300

      {
        "as":"AS14061 Digital Ocean, Inc.",
        "city":"Clifton",
        "country":"United States",
        "countryCode":"US",
        "isp":"Digital Ocean",
        "lat":40.8326,
        "lon":-74.1307,
        "org":"Digital Ocean",
        "query":"104.131.124.203",
        "region":"NJ",
        "regionName":"New Jersey",
        "status":"success",
        "timezone":"America/New_York",
        "zip":"07014"
      }
    */
  });
});

// Failed to establish proxy connection to destination.
client.on('error', () => {
  // Handle errors
});

// Start connection
client.connect();

## Migrating from v1

For the most part, migrating from v1 takes minimal effort as v2 still supports factory creation of proxy connections with callback support.

### Notable breaking changes

- In an options object, the proxy 'command' is now required and does not default to 'connect'.
- **In an options object, 'target' is now known as 'destination'.**
- Sockets are no longer paused after a SOCKS connection is made, so socket.resume() is no longer required. (Please be sure to attach data handlers immediately to the Socket to avoid losing data).
- In v2, only the 'connect' command is supported via the factory SocksClient.createConnection function. (BIND and ASSOCIATE must be used with a SocksClient instance via event handlers).
- In v2, the factory SocksClient.createConnection function callback is called with a single object rather than separate socket and info object.
- A SOCKS http/https agent is no longer bundled into the library.

For informational purposes, here is the original getting started example from v1 converted to work with v2.

### Before (v1)

```javascript
var Socks = require('socks');

var options = {
    proxy: {
        ipaddress: "202.101.228.108",
        port: 1080,
        type: 5
    },
    target: {
        host: "google.com",
        port: 80
    },
    command: 'connect'
};

Socks.createConnection(options, function(err, socket, info) {
    if (err)
        console.log(err);
    else {
        socket.write("GET / HTTP/1.1\nHost: google.com\n\n");
        socket.on('data', function(data) {
            console.log(data.length);
            console.log(data);
        });

        // PLEASE NOTE: sockets need to be resumed before any data will come in or out as they are paused right before this callback is fired.
        socket.resume();

        // 569
        // <Buffer 48 54 54 50 2f 31 2e 31 20 33 30 31 20 4d 6f 76 65 64 20 50 65...
    }
});
```

### After (v2)
```javascript
const SocksClient = require('socks').SocksClient;

let options = {
    proxy: {
        ipaddress: "202.101.228.108",
        port: 1080,
        type: 5
    },
    destination: {
        host: "google.com",
        port: 80
    },
    command: 'connect'
};

SocksClient.createConnection(options, function(err, result) {
    if (err)
        console.log(err);
    else {
        result.socket.write("GET / HTTP/1.1\nHost: google.com\n\n");
        result.socket.on('data', function(data) {
            console.log(data.length);
            console.log(data);
        });

        // 569
        // <Buffer 48 54 54 50 2f 31 2e 31 20 33 30 31 20 4d 6f 76 65 64 20 50 65...
    }
});

          within such NOTICE file, excluding those notices that do not
          pertain to any part of the Derivative Works, in at least one
          of the following places: within a NOTICE text file distributed
          as part of the Derivative Works; within the Source form or
          documentation, if provided along with the Derivative Works; or,
          within a display generated by the Derivative Works, if and
          wherever such third-party notices normally appear. The contents
          of the NOTICE file are for informational purposes only and
          do not modify the License. You may add Your own attribution

      any Contribution intentionally submitted for inclusion in the Work
      by You to the Licensor shall be under the terms and conditions of
      this License, without any additional terms or conditions.
      Notwithstanding the above, nothing herein shall supersede or modify
      the terms of any separate license agreement you may have executed
      with Licensor regarding such Contributions.

   6. Trademarks. This License does not grant permission to use the trade
      names, trademarks, service marks, or product names of the Licensor,

      origin of the Work and reproducing the content of the NOTICE file.

   7. Disclaimer of Warranty. Unless required by applicable law or
      agreed to in writing, Licensor provides the Work (and each
      Contributor provides its Contributions) on an "AS IS" BASIS,
      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
      implied, including, without limitation, any warranties or conditions
      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
      PARTICULAR PURPOSE. You are solely responsible for determining the
      appropriateness of using or redistributing the Work and assume any
      risks associated with Your exercise of permissions under this License.

   8. Limitation of Liability. In no event and under no legal theory,
      whether in tort (including negligence), contract, or otherwise,
      unless required by applicable law (such as deliberate and grossly
      negligent acts) or agreed to in writing, shall any Contributor be
      liable to You for damages, including any direct, indirect, special,
      incidental, or consequential damages of any character arising as a
      result of this License or out of the use or inability to use the
      Work (including but not limited to damages for loss of goodwill,
      work stoppage, computer failure or malfunction, or any and all
      other commercial damages or losses), even if such Contributor
      has been advised of the possibility of such damages.

   9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
      of your accepting any such warranty or additional liability.

      "Source" form shall mean the preferred form for making modifications,
      including but not limited to software source code, documentation
      source, and configuration files.

      "Object" form shall mean any form resulting from mechanical
      transformation or translation of a Source form, including but
      not limited to compiled object code, generated documentation,
      and conversions to other media types.

      "Work" shall mean the work of authorship, whether in Source or
      Object form, made available under the License, as indicated by a
      copyright notice that is included in or attached to the work
      (an example is provided in the Appendix below).

      "Derivative Works" shall mean any work, whether in Source or Object
      form, that is based on (or derived from) the Work and for which the
      editorial revisions, annotations, elaborations, or other modifications
      represent, as a whole, an original work of authorship. For the purposes
      of this License, Derivative Works shall not include works that remain
      separable from, or merely link (or bind by name) to the interfaces of,
      the Work and Derivative Works thereof.

      "Contribution" shall mean any work of authorship, including
      the original version of the Work and any modifications or additions
      to that Work or Derivative Works thereof, that is intentionally
      submitted to Licensor for inclusion in the Work by the copyright owner
      or by an individual or Legal Entity authorized to submit on behalf of
      the copyright owner. For the purposes of this definition, "submitted"
      means any form of electronic, verbal, or written communication sent

      communication on electronic mailing lists, source code control systems,
      and issue tracking systems that are managed by, or on behalf of, the
      Licensor for the purpose of discussing and improving the Work, but
      excluding communication that is conspicuously marked or otherwise
      designated in writing by the copyright owner as "Not a Contribution."

      "Contributor" shall mean Licensor and any individual or Legal Entity
      on behalf of whom a Contribution has been received by Licensor and
      subsequently incorporated within the Work.

   2. Grant of Copyright License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      copyright license to reproduce, prepare Derivative Works of,
      publicly display, publicly perform, sublicense, and distribute the
      Work and such Derivative Works in Source or Object form.

   3. Grant of Patent License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      (except as stated in this section) patent license to make, have made,
      use, offer to sell, sell, import, and otherwise transfer the Work,
      where such license applies only to those patent claims licensable
      by such Contributor that are necessarily infringed by their
      Contribution(s) alone or by combination of their Contribution(s)
      with the Work to which such Contribution(s) was submitted. If You
      institute patent litigation against any entity (including a
      cross-claim or counterclaim in a lawsuit) alleging that the Work
      or a Contribution incorporated within the Work constitutes direct
      or contributory patent infringement, then any patent licenses
      granted to You under this License for that Work shall terminate
      as of the date such litigation is filed.

   4. Redistribution. You may reproduce and distribute copies of the
      Work or Derivative Works thereof in any medium, with or without
      modifications, and in Source or Object form, provided that You
      meet the following conditions:

      (a) You must give any other recipients of the Work or
          Derivative Works a copy of this License; and

      (b) You must cause any modified files to carry prominent notices
          stating that You changed the files; and

      (c) You must retain, in the Source form of any Derivative Works
          that You distribute, all copyright, patent, trademark, and
          attribution notices from the Source form of the Work,
          excluding those notices that do not pertain to any part of
          the Derivative Works; and

      (d) If the Work includes a "NOTICE" text file as part of its
          distribution, then any Derivative Works that You distribute must
          include a readable copy of the attribution notices contained
          within such NOTICE file, excluding those notices that do not
          pertain to any part of the Derivative Works, in at least one
          of the following places: within a NOTICE text file distributed
          as part of the Derivative Works; within the Source form or
          documentation, if provided along with the Derivative Works; or,
          within a display generated by the Derivative Works, if and
          wherever such third-party notices normally appear. The contents
          of the NOTICE file are for informational purposes only and
          do not modify the License. You may add Your own attribution
          notices within Derivative Works that You distribute, alongside
          or as an addendum to the NOTICE text from the Work, provided
          that such additional attribution notices cannot be construed
          as modifying the License.

      You may add Your own copyright statement to Your modifications and
      may provide additional or different license terms and conditions
      for use, reproduction, or distribution of Your modifications, or
      for any such Derivative Works as a whole, provided Your use,
      reproduction, and distribution of the Work otherwise complies with
      the conditions stated in this License.

   5. Submission of Contributions. Unless You explicitly state otherwise,
      any Contribution intentionally submitted for inclusion in the Work
      by You to the Licensor shall be under the terms and conditions of
      this License, without any additional terms or conditions.
      Notwithstanding the above, nothing herein shall supersede or modify
      the terms of any separate license agreement you may have executed
      with Licensor regarding such Contributions.

   6. Trademarks. This License does not grant permission to use the trade
      names, trademarks, service marks, or product names of the Licensor,
      except as required for reasonable and customary use in describing the
      origin of the Work and reproducing the content of the NOTICE file.

   7. Disclaimer of Warranty. Unless required by applicable law or
      agreed to in writing, Licensor provides the Work (and each
      Contributor provides its Contributions) on an "AS IS" BASIS,
      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
      implied, including, without limitation, any warranties or conditions
      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
      PARTICULAR PURPOSE. You are solely responsible for determining the
      appropriateness of using or redistributing the Work and assume any
      risks associated with Your exercise of permissions under this License.

   8. Limitation of Liability. In no event and under no legal theory,
      whether in tort (including negligence), contract, or otherwise,
      unless required by applicable law (such as deliberate and grossly
      negligent acts) or agreed to in writing, shall any Contributor be
      liable to You for damages, including any direct, indirect, special,
      incidental, or consequential damages of any character arising as a
      result of this License or out of the use or inability to use the
      Work (including but not limited to damages for loss of goodwill,
      work stoppage, computer failure or malfunction, or any and all
      other commercial damages or losses), even if such Contributor
      has been advised of the possibility of such damages.

   9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
      of your accepting any such warranty or additional liability.

   END OF TERMS AND CONDITIONS

   APPENDIX: How to apply the Apache License to your work.

# which

Like the unix `which` utility.

Finds the first instance of a specified executable in the PATH
environment variable.  Does not cache the results, so `hash -r` is not
needed when the PATH changes.

## USAGE

```javascript
const which = require('which')

// async usage
// rejects if not found
const resolved = await which('node')

// if nothrow option is used, returns null if not found
const resolvedOrNull = await which('node', { nothrow: true })

// sync usage
// throws if not found
const resolved = which.sync('node')

// if nothrow option is used, returns null if not found
const resolvedOrNull = which.sync('node', { nothrow: true })

// Pass options to override the PATH and PATHEXT environment vars.
await which('node', { path: someOtherPath, pathExt: somePathExt })
```

## CLI USAGE

Just like the BSD `which(1)` binary but using `node-which`.

```
usage: node-which [-as] program ...
```

You can learn more about why the binary is `node-which` and not `which` 
[here](https://github.com/npm/node-which/pull/67)

## OPTIONS

You may pass an options object as the second argument.

- `path`: Use instead of the `PATH` environment variable.
- `pathExt`: Use instead of the `PATHEXT` environment variable.
- `all`: Return all matches, instead of just the first one.  Note that
  this means the function returns an array of strings instead of a
  single string.
#!/usr/bin/env node
