# grunt-sloc

> It's SLOC plugin for Grunt.js. based on [sloc](https://npmjs.org/package/sloc)

## Getting Started
This plugin requires Grunt `~0.4.1`

If you haven't used [Grunt](http://gruntjs.com/) before, be sure to check out the [Getting Started](http://gruntjs.com/getting-started) guide, as it explains how to create a [Gruntfile](http://gruntjs.com/sample-gruntfile) as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:

```shell
npm install grunt-sloc --save-dev
```

Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:

```js
grunt.loadNpmTasks('grunt-sloc');
```

## The "sloc" task

### Overview
In your project's Gruntfile, add a section named `sloc` to the data object passed into `grunt.initConfig()`.

```js
grunt.initConfig({
  sloc: {
    options: {
      // Task-specific options go here.
    },
    your_target: {
      // Target-specific file lists and/or options go here.
    },
  },
})
```

### Options

#### options.reportType
Type: `String`
Default value: `stdout`

It will generate a JSON file SLOC analysis results. The default value is `stdout`.
If we do not specify, in the case of the `stdout`, If you are prompted to enter the `json` and output to the CLI on the json file.

#### options.reportPath
Type: `String`
Default value: ``

| extension | total | source | comment | single | mixed | empty | block |
|-----------|-------|--------|---------|--------|-------|-------|-------|
| js        |    11 |      8 |       2 |      2 |     0 |     1 |     0 |
| css       |     8 |      7 |       0 |      0 |     0 |     1 |     0 |
| less      |   235 |    152 |      45 |     30 |     0 |    38 |    15 |
'-----------------------------------------------------------------------'
```

#### options.tolerant
Type: `Boolean`
Default value: `false`

Set as `false` to analyze only files with a subset of popular extensions.  `true` to analyze files with *any* file extension.  The default is `false`.

If `true`, the SLOC will be executed on all of the files specified, regardless of file extension.  With 'tolerant' set to `false`, or 'tolerant' unspecified, only supported file extensions will be analyzed.

#### options.alias
Type: `Object`
Default value: `null`

Custom ext to act like standard ext.

eg.

```js
{
  php5: 'php',
  less: 'css',
  vm: 'html'
}
```


### Usage Examples

#### Basic SLOC
This configuration will count line of the input files using the default options.

```js
grunt.initConfig({
  sloc: {
    'my-source-files': {
      files: {
        'path/to/target': [ 'lib/onlyMyLib.js', 'app/**.js' ],
        'path/to/others': [ '*.java', '*.coffee' ],
      }
    }
  }
})
```

**result**

```
...

#### Custom Options

<!--
In this example, custom options are used to do something else with whatever else. So if the `testing` file has the content `Testing` and the `123` file had the content `1 2 3`, the generated result in this case would be `Testing: 1 2 3 !!!`
-->

```js
grunt.initConfig({
  sloc: {
    options: {
      reportType: 'json',
      reportPath: 'path/to/sloc-v<%= pkg.version %>.json',
    },
    files: {
      'path/to/target': [ 'lib/onlyMyLib.js', 'app/**.js' ],
      'path/to/others': [ '*.java', '*.coffee' ]
    },
  },
})
```
