This package is a unified (rehype) plugin to support retext.
unified is a project that transforms content with abstract syntax trees (ASTs). rehype adds support for HTML to unified. retext adds support for natural language to unified. hast is the HTML AST that rehype uses. nlcst is the natural language AST that retext uses. This is a rehype plugin that transforms hast into nlcst to support retext.
This project is useful if you want to check natural language in HTML.
The retext ecosystem has many useful plugins to check prose, such as
retext-indefinite-article
which checks that a
and an
are used correctly, or retext-readability
which
checks that sentences are not too complex.
This plugins lets you use them on HTML documents.
This plugin is not able to apply changes by retext plugins (such
as done by retext-smartypants
) to the HTML content.
This plugin is built on hast-util-to-nlcst
, which does
the work on syntax trees.
rehype focusses on making it easier to transform content by abstracting such
internals away.
This package is ESM only. In Node.js (version 16+), install with npm:
npm install rehype-retext
In Deno with esm.sh
:
import rehypeRetext from 'https://esm.sh/rehype-retext@5'
In browsers with esm.sh
:
<script type="module">
import rehypeRetext from 'https://esm.sh/rehype-retext@5?bundle'
</script>
Say we have the following file example.html
:
<!doctype html>
<meta charset=utf8>
<title>Hello!</title>
<article>
A implicit sentence.
<h1>This and and that.</h1>
</article>
…and our module example.js
looks as follows:
import rehypeParse from 'rehype-parse'
import rehypePresetMinify from 'rehype-preset-minify'
import rehypeRetext from 'rehype-retext'
import rehypeStringify from 'rehype-stringify'
import retextEnglish from 'retext-english'
import retextIndefiniteArticle from 'retext-indefinite-article'
import retextRepeatedWords from 'retext-repeated-words'
import {read} from 'to-vfile'
import {unified} from 'unified'
import {reporter} from 'vfile-reporter'
const file = await unified()
.use(rehypeParse)
.use(
rehypeRetext,
unified()
.use(retextEnglish)
.use(retextIndefiniteArticle)
.use(retextRepeatedWords)
)
.use(rehypePresetMinify)
.use(rehypeStringify)
.process(await read('example.html'))
console.error(reporter([file]))
console.log(String(file))
…then running node example.js
yields:
example.html
5:3-5:4 warning Unexpected article `A` before `implicit`, expected `An` retext-indefinite-article retext-indefinite-article
6:12-6:19 warning Unexpected repeated `and`, remove one occurrence and retext-repeated-words
⚠ 2 warnings
<!doctypehtml><meta charset=utf8><title>Hello!</title><article>A implicit sentence.<h1>This and and that.</h1></article>
This package exports no identifiers.
The default export is rehypeRetext
.
Bridge or mutate to retext.
Transform (Transformer
).
- if a processor is given, uses its parser to create a
new nlcst tree, then runs the plugins attached to with that
(bridge 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 is given, uses it to create a new nlcst tree,
and returns it (mutate mode); you can get a parser by
importing
Parser
fromretext-english
for example; other plugins used afterrehypeRetext
should be retext plugins
This package is fully typed with TypeScript. It exports no additional types.
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, rehype-retext@5
,
compatible with Node.js 16.
This plugin works with unified
version 6+, rehype
version 4+, and retext
version 7+.
rehype-retext
does not change the syntax tree so there are no openings for
cross-site scripting (XSS) attacks.
