[**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
|
|
```
|
|
|
|
## Use
|
|
|
|
```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.
