## What is this?

This package is a [unified][] processor with support for parsing Latin-script
natural language as input and serializing it as output by using unified with
[`retext-latin`][retext-latin] and [`retext-stringify`][retext-stringify].

See [the monorepo readme][retext] for info on what the retext ecosystem is.

## When should I use this?

You can use this package when you want to use unified, have Latin-script as
input, and as output.
This package is a shortcut for
`unified().use(retextLatin).use(retextStringify)`.
When the input isn’t Latin-script or is English or Dutch (meaning you don’t
need `retext-latin`), it’s recommended to use `unified` directly.

## Install

This package is [ESM only][esm].
In Node.js (version 16+), install with [npm][]:

```sh
npm install retext
```

In Deno with [`esm.sh`][esmsh]:

```js
import {retext} from 'https://esm.sh/retext@9'
```

In browsers with [`esm.sh`][esmsh]:

```html
<script type="module">
  import {retext} from 'https://esm.sh/retext@9?bundle'
</script>
```

## Use

```js
import {retext} from 'retext'
import retextEmoji from 'retext-emoji'
import retextProfanities from 'retext-profanities'
import {reporter} from 'vfile-reporter'

const file = await retext()
  .use(retextEmoji, {convert: 'encode'})
  .use(retextProfanities)
  .process('He’s set on beating your butt for sheriff! :cop:')

console.log(String(file))
console.error(reporter(file))
```

Yields:

```txt
He’s set on beating your butt for sheriff! 👮
```

```txt
1:26-1:30 warning Be careful with `butt`, it’s profane in some cases butt retext-profanities

⚠ 1 warning
```

## API

This package exports the identifier [`retext`][api-retext].
There is no default export.

### `retext()`

Create a new unified processor that already uses
[`retext-latin`][retext-latin] and [`retext-stringify`][retext-stringify].

You can add more plugins with `use`.
See [`unified`][unified] for more information.

## Syntax tree

The syntax tree used in retext is [nlcst][].

## Types

This package is fully typed with [TypeScript][].
It exports no additional types.

## Compatibility

Projects maintained by the unified collective are compatible with maintained
versions of Node.js.

When we cut a new major release, we drop support for unmaintained versions of
Node.
This means we try to keep the current release line, `retext@^9`, compatible
with Node.js 16.
