# esformatter-var-each [![Build status](https://travis-ci.org/twolfson/esformatter-var-each.png?branch=master)](https://travis-ci.org/twolfson/esformatter-var-each)

[Esformatter][] plugin that converts comma `var` statements into separate `var` statements

This was created to make obfuscated scripts more palatable. However, it should be a nice addition to your web development tasks.

[Esformatter]: https://github.com/millermedeiros/esformatter

**Features:**

- Preserves last character of `var's` (e.g. `var a, b;` -> `var a; var b;`)
- Maintain indentation level of `var's`

## Getting Started
Install the module with: `npm install esformatter-var-each`

Then, register it as a plugin and format your JS:

```js
// Load and register our plugin
var esformatter = require('esformatter');
var esformatterVarEach = require('esformatter-var-each');
esformatter.register(esformatterVarEach);

// Format our code
esformatter.format([
  'var a = \'hello\',',
  '    b = \'world\';'
].join('\n'));
// var a = 'hello';
// var b = 'world';
```

Alternatively, load it via `format` directly:

```js
var esformatter = require('esformatter');
esformatter.format([
  'var a = \'hello\',',
  '    b = \'world\';'
].join('\n'), {
  plugins: [
    'esformatter-var-each'
  ]
});
```

## Documentation
`esformatter-var-each` exposes `exports.transform` for consumption by `esformatter`.

### `esformatterVarEach.transform(ast)`
Walk [AST][] and splice in `var` statements.
