Usage and API reference

rehype-retext

rehype plugin to support retext.

Contents

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 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.

Install

This package is ESM only. In Node.js (version 12.20+, 14.14+, or 16.0+), install with npm:

npm install @stackline/rehype-retext

In Deno with Skypack:

import rehypeRetext from 'https://cdn.skypack.dev/rehype-retext@3?dts'

In browsers with Skypack:

<script type="module">
  import rehypeRetext from 'https://cdn.skypack.dev/rehype-retext@3?min'
</script>

Use

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 {read} from 'to-vfile'
import {reporter} from 'vfile-reporter'
import {unified} from 'unified'
import rehypeParse from 'rehype-parse'
import rehypePresetMinify from 'rehype-preset-minify'
import rehypeStringify from 'rehype-stringify'
import rehypeRetext from '@stackline/rehype-retext'
import retextEnglish from 'retext-english'
import retextIndefiniteArticle from 'retext-indefinite-article'
import retextRepeatedWords from 'retext-repeated-words'

main()

async function main() {
  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))
}

Now 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 is rehypeRetext.

unified().use(rehypeRetext, destination)

rehype plugin to support retext. There are no options but destination is required.

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). 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 rehype-retext.

As HTML defines paragraphs, that definition is used for Paragraphs: <p> and <h1-6> are explicitly supported, and implicit paragraphs in flow content are also supported.

Types

This package is fully typed with TypeScript. It exports the Parser and Processor types, which specify the interfaces of the accepted destination.

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+, 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) attacks.
