[**remark**][remark] is a markdown processor powered by [plugins][] part of the
[unified][] [collective][].

*   API by [`unified`][unified]
*   Parses markdown to the tree with [`remark-parse`][parse]
*   [**mdast**][mdast] syntax tree
*   [Plugins][] transform the tree
*   Compiles the tree to markdown using [`remark-stringify`][stringify]

Don’t need the parser?  Or the compiler?  [That’s OK][unified-usage].

## Installation

[npm][]:

```sh
npm install remark
```

## Usage

###### Common example

This example lints markdown and turns it into HTML.

```js
var remark = require('remark')
var recommended = require('remark-preset-lint-recommended')
var html = require('remark-html')
var report = require('vfile-reporter')

remark()
  .use(recommended)
  .use(html)
  .process('## Hello world!', function(err, file) {
    console.error(report(err || file))
    console.log(String(file))
  })
```

Yields:

```txt
1:1  warning  Missing newline character at end of file  final-newline  remark-lint

⚠ 1 warning
```

```html
<h2>Hello world!</h2>
```

###### Settings through data

This example prettifies markdown and configures [`remark-parse`][parse] and
[`remark-stringify`][stringify] through [data][].

```js
var remark = require('remark')

remark()
  .data('settings', {commonmark: true, emphasis: '*', strong: '*'})
  .process('_Emphasis_ and __importance__', function(err, file) {
    if (err) throw err
    console.log(String(file))
  })
```

Yields:

```markdown
*Emphasis* and **importance**
```

###### Settings through a preset

This example prettifies markdown and configures [`remark-parse`][parse] and
[`remark-stringify`][stringify] through a [preset][].

```js
var remark = require('remark')

remark()
  .use({
    settings: {commonmark: true, emphasis: '*', strong: '*'}
  })
  .process('_Emphasis_ and __importance__', function(err, file) {
    if (err) throw err
    console.log(String(file))
  })
```

Yields:

```markdown
*Emphasis* and **importance**
```
