retext plugin to check spacing between sentences.


What is this?

This package is a unified (retext) plugin to check spacing between sentences. For example, it can check for one or two spaces sentences.

When should I use this?

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


This package is ESM only. In Node.js (version 12.20+, 14.14+, 16.0+, or 18.0+), install with npm:

npm install retext-sentence-spacing

In Deno with esm.sh:

import retextSentenceSpacing from 'https://esm.sh/retext-sentence-spacing@5'

In browsers with esm.sh:

<script type="module">
  import retextSentenceSpacing from 'https://esm.sh/retext-sentence-spacing@5?bundle'


Say our document example.txt contains:

One sentence. Two sentences.

One sentence.  Two sentences.

…and our module example.js looks as follows:

import {read} from 'to-vfile'
import {reporter} from 'vfile-reporter'
import {retext} from 'retext'
import retextSentenceSpacing from 'retext-sentence-spacing'

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


…now running node example.js yields:

  3:14-3:16  warning  Expected `1` space between sentences, not `2`  space  retext-sentence-spacing

⚠ 1 warning

The default is to check for 1 space, which can be changed. For example, to 2 spaces:

 const file = await retext()
-  .use(retextSentenceSpacing)
+  .use(retextSentenceSpacing, {preferred: 2})
   .process(await read('example.txt'))

…now running node example.js once again yields:

  1:14-1:15  warning  Expected `2` spaces between sentences, not `1`  double-space  retext-sentence-spacing

⚠ 1 warning


This package exports no identifiers. The default export is retextSentenceSpacing.

unified().use(retextSentenceSpacing[, options])

Check spacing between sentences. Emit warnings when the spacing does not adhere to the preferred style.



Each message is emitted as a VFileMessage on file, with the following fields:


Name of this plugin ('retext-sentence-spacing').


Preferred style ('newline', 'space', or 'double-space').


Current not ok spacing (string, such as ' ').


List of suggestions of spacing to use (Array<string>, such as ['\n']).


This package is fully typed with TypeScript. It exports the additional type Options.


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+, 16.0+, and 18.0+. Our projects sometimes work with older versions, but this is not guaranteed.
