## What is this?



This package is a [unified][] ([remark][]) plugin to support [retext][].



## When should I use this?



This project is useful if you want to check natural language in markdown.

The retext ecosystem has many useful plugins to check prose, such as

[`retext-indefinite-article`][retext-indefinite-article] which checks that `a`

and `an` are used correctly, or [`retext-readability`][retext-readability] which

checks that sentences are not too complex.

This plugins lets you use them on markdown documents.



This plugin is not able to apply changes by retext plugins (such

as done by `retext-smartypants`) to the markdown content.



This plugin is built on [`mdast-util-to-nlcst`][mdast-util-to-nlcst], which does

the work on syntax trees.

remark focusses on making it easier to transform content by abstracting such

internals away.



## Install



This package is [ESM only][esm].

In Node.js (version 16+), install with [npm][]:



```sh

npm install remark-retext

```



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



```js

import remarkRetext from 'https://esm.sh/remark-retext@6'

```



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



```html



  import remarkRetext from 'https://esm.sh/remark-retext@6?bundle'



```



## Use



Say we have the following file `example.md`:



```markdown

## Hello guys!

```



…and a module `example.js`:



```js

import remarkParse from 'remark-parse'

import remarkRetext from 'remark-retext'

import remarkStringify from 'remark-stringify'

import retextEnglish from 'retext-english'

import retextEquality from 'retext-equality'

import {read} from 'to-vfile'

import {unified} from 'unified'

import {reporter} from 'vfile-reporter'



const file = await unified()

  .use(remarkParse)

  .use(remarkRetext, unified().use(retextEnglish).use(retextEquality))

  .use(remarkStringify)

  .process(await read('example.md'))



console.error(reporter(file))

```



…then running `node example.js` yields:



```text

example.md

1:10-1:14 warning Unexpected potentially insensitive use of `guys`, in somes cases `people`, `persons`, `folks` may be better gals-man retext-equality



⚠ 1 warning

```



## API



This package exports no identifiers.

The default export is [`remarkRetext`][api-remark-retext].



### `unified().use(remarkRetext, destination[, options])`



Bridge or mutate to retext.



###### Parameters



*   `destination` ([`Parser`][unified-parser] or

    [`Processor`][unified-processor])

    — configuration (required)



###### Returns



Transform ([`Transformer`][unified-transformer]).



###### Notes



*   if a [processor][unified-processor] is given, uses its parser to create a

    new nlcst tree, then runs the plugins attached to with that

    (*[bridge mode][unified-mode]*); you can add a parser to processor for

    example with `retext-english`; other plugins used on the processor should

    be retext plugins

*   if a [parser][unified-parser] is given, uses it to create a new nlcst tree,

    and returns it (*[mutate mode][unified-mode]*); you can get a parser by

    importing `Parser` from `retext-english` for example;  other plugins used

    after `remarkRetext` should be retext plugins



### `Options`



Configuration (TypeScript type).



###### Fields



*   `options.ignore` (`Array`, optional)

    — list of [mdast][] node types to ignore;

    the types `'table'`, `'tableRow'`, and `'tableCell'` are always ignored

*   `options.source` (`Array`, optional)

    — list of [mdast][] node types to mark as [nlcst][] source nodes;

    the type `'inlineCode'` is always marked as source



## Types



This package is fully typed with [TypeScript][].

It exports the additional type [`Options`][api-options].



## 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, `remark-retext@^6`,

compatible with Node.js 16.



This plugin works with `unified` version 6+, `remark` version 3+, and `retext`

version 7+.



## Security



Use of `remark-retext` does not involve **[rehype][]** (**[hast][]**) or user

content so there are no openings for [cross-site scripting (XSS)][wiki-xss]

attacks.
