retext plugin to check for redundant acronyms (such as ATM machine to ATM).


What is this?

This package is a unified (retext) plugin to check for redundant acronyms (such as ATM machine to ATM).

🙂 Fun fact: this is called RAS syndrome (redundant acronym syndrome syndrome).

When should I use this?

You can opt-into this plugin when you’re dealing with content that might contain grammar mistakes, and have authors that can fix that content.


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

npm install retext-redundant-acronyms

In Deno with esm.sh:

import retextRedundantAcronyms from 'https://esm.sh/retext-redundant-acronyms@5'

In browsers with esm.sh:

<script type="module">
  import retextRedundantAcronyms from 'https://esm.sh/retext-redundant-acronyms@5?bundle'


Say our document example.txt contains:

Where can I find an ATM machine?

…and our module example.js contains:

import retextEnglish from 'retext-english'
import retextRedundantAcronyms from 'retext-redundant-acronyms'
import retextStringify from 'retext-stringify'
import {read} from 'to-vfile'
import {unified} from 'unified'
import {reporter} from 'vfile-reporter'

const file = await unified()
  .process(await read('example.txt'))


…then running node example.js yields:

1:21-1:32 warning Unexpected redundant `ATM machine`, expected `ATM` atm retext-redundant-acronyms

⚠ 1 warning

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-redundant-acronyms@^5, compatible with Node.js 16.
