What is this?

This package is a utility that removes empty paragraphs, left over from other operations, from the tree. Paragraphs are considered empty if they do not contain non-whitespace characters.

When should I use this?

Probably never! You should try to clean your trees yourself.

A plugin, remark-squeeze-paragraphs, exists that does the same but for remark.

Install

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

npm install mdast-util-squeeze-paragraphs

In Deno with esm.sh:

import {squeezeParagraphs} from 'https://esm.sh/mdast-util-squeeze-paragraphs@5'

In browsers with esm.sh:

<script type="module">
  import {squeezeParagraphs} from 'https://esm.sh/mdast-util-squeeze-paragraphs@5?bundle'
</script>

Use

import {u} from 'unist-builder'
import {squeezeParagraphs} from 'mdast-squeeze-paragraphs'

const tree = u('root', [
  u('paragraph', []),
  u('paragraph', [u('text', 'Alpha')]),
  u('paragraph', [u('text', ' ')])
])

squeezeParagraphs(tree)

console.dir(tree, {depth: null})

Yields:

{ type: 'root',
  children:
   [ { type: 'paragraph',
       children: [ { type: 'text', value: 'Alpha' } ] } ] }
