retext plugin to classify URL-like values as syntax instead of natural language.


What is this?

This package is a unified (retext) plugin to classify URL-like values (such as example.com, index.html, or www.alpha.bravo) as SourceNode instead of natural language. That node represent “external (ungrammatical) values” instead of natural language, which hides URLs and paths from retext-spell, retext-readability, retext-equality, and other things that check words.

When should I use this?

You can use this plugin any time there are URLs and paths in prose, that are (incorrectly) warned about by linting plugins.

👉 Note: this is not a markdown parser. Use unified with remark-parse and remark-retext to “hide” other syntax.


This package is ESM only. In Node.js (version 16+), install with npm:

npm install retext-syntax-urls

In Deno with esm.sh:

import retextSyntaxUrls from 'https://esm.sh/retext-syntax-urls@4'

In browsers with esm.sh:

<script type="module">
  import retextSyntaxUrls from 'https://esm.sh/retext-syntax-urls@4?bundle'


Without retext-syntax-urls:

import dictionaryEn from 'dictionary-en'
import retextEnglish from 'retext-english'
import retextSpell from 'retext-spell'
import retextStringify from 'retext-stringify'
import retextSyntaxUrls from 'retext-syntax-urls'
import {unified} from 'unified'
import {reporter} from 'vfile-reporter'

const file = await unified()
  .use(retextSpell, dictionaryEn)
  .process('Have you read readme.md? Check it out: www.example.com/readme.md')

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, retext-syntax-urls@^4, compatible with Node.js 16.
