What is this?
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.
When should I use this?
This project is useful if you want to check natural language in HTML. 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 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
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.Install
This package is ESM onlyesm. In Node.js (version 16+), install with npm:npm install rehype-retext
In Deno with
esm.sh
esmsh:import rehypeRetext from 'https://esm.sh/rehype-retext@4'
In browsers with
esm.sh
esmsh:<script type="module">
import rehypeRetext from 'https://esm.sh/rehype-retext@4?bundle'
</script>
Use
Say we have the following fileexample.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 Use `An` before `implicit`, not `A` retext-indefinite-article retext-indefinite-article
6:12-6:19 warning Expected `and` once, not twice and retext-repeated-words
⚠ 2 warnings
<!doctypehtml><meta charset=utf8><title>Hello!</title><article>A implicit sentence.<h1>This and and that.</h1></article>
API
This package exports no identifiers. The default export isrehypeRetext
api-rehype-retext.unified().use(rehypeRetext, options)
Bridge or mutate to retext.Parameters
options
(Parser
unified-parser orProcessor
unified-processor)
— configuration (required)
Returns
Transform (Transformer
unified-transformer).Notes
- if a processorunified-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 parserunified-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 `rehypeRetext` should be retext plugins
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,
rehype-retext@^4
,
compatible with Node.js 16.This plugin works with
unified
version 6+, rehype
version 4+, and retext
version 7+.Security
rehype-retext
does not change the syntax tree so there are no openings for
cross-site scripting (XSS)xss attacks.Related
