[**remark**][remark] plugin to bridge or mutate to [**rehype**][rehype].
> Note: `remark-rehype` doesn’t deal with HTML inside the Markdown.
> You’ll need [`rehype-raw`][raw] if you’re planning on doing that.
## Install
[npm][]:
```sh
npm install remark-rehype
```
## Use
Say we have the following file, `example.md`:
```markdown
# Hello world
> Block quote.
Some _emphasis_, **importance**, and `code`.
```
And our script, `example.js`, looks as follows:
```js
var vfile = require('to-vfile')
var report = require('vfile-reporter')
var unified = require('unified')
var markdown = require('remark-parse')
var remark2rehype = require('remark-rehype')
var doc = require('rehype-document')
var format = require('rehype-format')
var html = require('rehype-stringify')
unified()
.use(markdown)
.use(remark2rehype)
.use(doc)
.use(format)
.use(html)
.process(vfile.readSync('example.md'), function(err, file) {
console.error(report(err || file))
console.log(String(file))
})
```
Now, running `node example` yields:
```html
example.md: no issues found
example
Hello world
Block quote.
Some emphasis, importance, and code.
```
## API
### `origin.use(remark2rehype[, destination][, options])`
[**remark**][remark] ([**mdast**][mdast]) plugin to bridge or mutate to
[**rehype**][rehype] ([**hast**][hast]).
###### `destination`
If a [`Unified`][processor] processor is given, runs the destination processor
with the new hast tree, then, after running discards that tree and continues on
running the origin processor with the original tree ([*bridge mode*][bridge]).
Otherwise, passes the tree to further plugins (*mutate mode*).
###### `options`
Passed to [`mdast-util-to-hast`][to-hast].
