Extension for mdast-util-from-markdown and/or mdast-util-to-markdown to support GitHub flavored markdown in mdast. When parsing (from-markdown), must be combined with micromark-extension-gfm.

You probably shouldn’t use this package directly, but instead use remark-gfm with remark.

Alternatively, the extensions can be used separately:

Install

npm:

npm install mdast-util-gfm

Use

Say we have the following file, example.md:

# GFM

## Autolink literals

www.example.com, https://example.com, and contact@example.com.

## Strikethrough

~one~ or ~~two~~ tildes.

## Table

| a | b  |  c |  d  |
| - | :- | -: | :-: |

## Tasklist

* [ ] to do
* [x] done

And our script, example.js, looks as follows:

var fs = require('fs')
var fromMarkdown = require('mdast-util-from-markdown')
var toMarkdown = require('mdast-util-to-markdown')
var syntax = require('micromark-extension-gfm')
var gfm = require('mdast-util-gfm')

var doc = fs.readFileSync('example.md')

var tree = fromMarkdown(doc, {
  extensions: [syntax()],
  mdastExtensions: [gfm.fromMarkdown]
})

console.log(tree)

var out = toMarkdown(tree, {extensions: [gfm.toMarkdown()]})

console.log(out)

Now, running node example yields:

{
  type: 'root',
  children: [
    {type: 'heading', depth: 1, children: [{type: 'text', value: 'GFM'}]},
    {
      type: 'heading',
      depth: 2,
      children: [{type: 'text', value: 'Autolink literals'}]
    },
    {
      type: 'paragraph',
      children: [
