What is this?
This package is a unified (remark) plugin to support retext.unified is a project that transforms content with abstract syntax trees (ASTs). remark adds support for markdown to unified. retext adds support for natural language to unified. mdast is the markdown AST that remark uses. nlcst is the natural language AST that retext uses. This is a remark plugin that transforms mdast into nlcst 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 asretext-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 unfortunately not able to apply changes by retext plugins (such as done by
retext-smartypants
) to the markdown content.Install
This package is ESM only. In Node.js (version 12.20+, 14.14+, or 16.0+), install with npm:npm install remark-retext
In Deno with Skypack:
import remarkRetext from 'https://cdn.skypack.dev/remark-retext@5?dts'
In browsers with Skypack:
<script type="module">
import remarkRetext from 'https://cdn.skypack.dev/remark-retext@5?min'
</script>
Use
Say we have the following file,example.md
:## Hello guys!
And our script,
example.js
, looks as follows:import {read} from 'to-vfile'
import {reporter} from 'vfile-reporter'
import {unified} from 'unified'
import remarkParse from 'remark-parse'
import remarkStringify from 'remark-stringify'
import remarkRetext from 'remark-retext'
import retextEnglish from 'retext-english'
import retextEquality from 'retext-equality'
main()
async function main() {
const file = await unified()
.use(remarkParse)
.use(remarkRetext, unified().use(retextEnglish).use(retextEquality))
.use(remarkStringify)
.process(await read('example.md'))
console.error(reporter(file))
}
Now, running
node example
yields:example.md

API
This package exports no identifiers. The default export isremarkRetext
.unified().use(remarkRetext, destination[, options])
remark plugin to support retext.destination
destination
is either a parser or a processor.- If a destination processor is given, runs the plugins attached to it
with the new nlcst tree ([*bridge mode*][bridge]).
This given processor must have a parser attached (this can be done by using
the plugin `retext-english` or similar) and should use other retext plugins
- If a parser is given, runs further plugins attached to the same processor
with the new tree (*mutate mode*).
Such parsers are exported by packages like `retext-english` as `Parser`.
You should use other retext plugins after `remark-retext`.
options
Configuration (Object
, optional).options.ignore
List of mdast node types to ignore (Array.<string>
).
The types 'table'
, 'tableRow'
, and 'tableCell'
are always ignored.options.source
List of mdast node types to mark as nlcst source nodes
(Array.<string>
).
'inlineCode'
is always marked as source.Examples
Example: mutate mode
The previous example was using bridge mode: the markdown AST remained for other plugins afterremark-retext
.
This example uses mutate mode: the markdown AST is discarded and the natural
language AST.
This is not very useful: this is not a good way to get the plain text version
of a markdown document.import {read} from 'to-vfile'
import {reporter} from 'vfile-reporter'
import {unified} from 'unified'
import remarkParse from 'remark-parse'
import remarkRetext from 'remark-retext'
import {Parser} from 'retext-english'
import retextEquality from 'retext-equality'
import retextStringify from 'retext-stringify'
main()
async function main() {
const file = await unified()
.use(remarkParse)
.use(remarkRetext, Parser)
.use(retextEquality)
.use(retextStringify)
.process(await read('example.md'))
console.error(reporter(file))
console.log(String(file))
}
…yields:
example.md

Types
This package is fully typed with TypeScript. It exports anOptions
type, which specifies the interface of the accepted
options.Compatibility
Projects maintained by the unified collective are compatible with all maintained versions of Node.js. As of now, that is Node.js 12.20+, 14.14+, and 16.0+. Our projects sometimes work with older versions, but this is not guaranteed.This plugin works with
unified
version 6+, remark
version 3+, and retext
version 7+.Security
Use ofremark-retext
does not involve rehyperehype (hasthast)
or user content so there are no openings for cross-site scripting (XSS)xss
attacks.Related
