Extension for [`mdast-util-from-markdown`][from-markdown] and/or
[`mdast-util-to-markdown`][to-markdown] to support GitHub flavored markdown
autolink literals in **[mdast][]**.
When parsing (`from-markdown`), must be combined with
[`micromark-extension-gfm-autolink-literal`][extension].

You might want to use this package through [`remark-gfm`][remark-gfm] with
**[remark][]**.

## Install

[npm][]:

```sh
npm install mdast-util-gfm-autolink-literal
```

## Use

Say our script, `example.js`, looks as follows:

```js
var fromMarkdown = require('mdast-util-from-markdown')
var toMarkdown = require('mdast-util-to-markdown')
var syntax = require('micromark-extension-gfm-autolink-literal')
var autolinkLiteral = require('mdast-util-gfm-autolink-literal')

var doc = 'www.example.com, https://example.com, and contact@example.com.'

var tree = fromMarkdown(doc, {
  extensions: [syntax],
  mdastExtensions: [autolinkLiteral.fromMarkdown]
})

console.log(tree)

var out = toMarkdown(tree, {extensions: [autolinkLiteral.toMarkdown]})

console.log(out)
```

Now, running `node example` yields:

```js
{
  type: 'root',
  children: [
    {
      type: 'paragraph',
      children: [
        {
          type: 'link',
          title: null,
          url: 'http://www.example.com',
          children: [{type: 'text', value: 'www.example.com'}]
        },
        {type: 'text', value: ', '},
        {
          type: 'link',
          title: null,
          url: 'https://example.com',
          children: [{type: 'text', value: 'https://example.com'}]
        },
        {type: 'text', value: ', and '},
        {
          type: 'link',
          title: null,
          url: 'mailto:contact@example.com',
          children: [{type: 'text', value: 'contact@example.com'}]
        },
        {type: 'text', value: '.'}
      ]
    }
  ]
}
```

```markdown
[www.example.com](http://www.example.com), <https://example.com>, and <contact@example.com>.
```
