[**mdast**][mdast] utility to make trees compact: collapse text nodes (when
possible) and blockquotes (in commonmark mode).

## Install

[npm][]:

```sh
npm install mdast-util-compact
```

## Usage

```js
var u = require('unist-builder')
var compact = require('mdast-util-compact')

var tree = u('strong', [u('text', 'alpha'), u('text', ' '), u('text', 'bravo')])

compact(tree)

console.log(tree)
```

Yields:

```js
{ type: 'strong',
  children: [ { type: 'text', value: 'alpha bravo' } ] }
```

## API

### `compact(tree[, commonmark])`

Walk the [tree][] and collapse nodes.
Combines adjacent [text][]s (but not when they represent entities or escapes).
If `commonmark` is `true`, collapses [blockquote][]s.

Handles [positional information][position-information] properly.

###### Returns

The given `tree`.

## Security

Use of `mdast-util-compact` does not involve [**hast**][hast] or user content
so there are no openings for [cross-site scripting (XSS)][xss] attacks.
