## 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:

```sh
npm install grunt-literate --save-dev
```

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

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

## The "literate" task

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

```js
grunt.initConfig({
  literate: {
     "README.md": "lib/foobar.js"
  }
});
```

The source will be parsed as JavaScript, and `/** ... ` comments extracted to the destination file.
This example uses markdown, but you are free to use any format, or even just plain text.

### Options

- `boolean code = false`, whether to include code parts or not

### Directives

Comments starting with triple slash `///` are directive comments. Currently supported directives are:

- `include` _filename_: include process _filename_ here.
- `plain` _filename_: include _filename_ here, without any processing, as is.



## beautiful-docs

This package plays well with [beautiful-docs](http://beautifuldocs.com/) and [grunt-beautiful-docs](https://www.npmjs.org/package/grunt-beautiful-docs) especially.

It's easy to start, you only need to configure `literate` and `bfdocs` tasks:

```js
grunt.initConfig({
  literate: {
     "README.md": ["lib/*.js"]
  },
  bfdocs: {
    docs: {
      options: {
        title: "My fabulous documentation",
        manifest: {
          files: [ "README.md" ],
        },
        dest: "doc/",
        theme: "default",
      }
    }
  },
});
```

or check [`Gruntfile.js`](https://github.com/phadej/grunt-literate/blob/master/Gruntfile.js) in the repository for the real example.
