mdast-util-gfm-autolink-literal

What is mdast-util-gfm-autolink-literal?

The mdast-util-gfm-autolink-literal npm package is a utility to support GitHub Flavored Markdown (GFM) autolink literals in mdast syntax trees. It helps parse and serialize autolink literals like URLs and email addresses directly in Markdown documents, making them clickable links without additional markup.

What are mdast-util-gfm-autolink-literal's main functionalities?

Parsing GFM Autolink Literals

This code sample demonstrates how to set up a processor using Unified with the remark-parse and remark-gfm plugins, enhanced by mdast-util-gfm-autolink-literal to automatically parse URLs written in plain text as autolink literals in the Markdown document.

import { unified } from 'unified';
import markdown from 'remark-parse';
import gfm from 'remark-gfm';
import gfmAutolinkLiteral from 'mdast-util-gfm-autolink-literal';

const processor = unified()
  .use(markdown)
  .use(gfm)
  .use(gfmAutolinkLiteral);

const tree = processor.parse('See https://example.com for more info.');
console.log(tree);

README

mdast-util-gfm-autolink-literal

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

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

Install

npm:

npm install mdast-util-gfm-autolink-literal

Use

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

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

var doc = 'www.example.com, https://example.com, and [e-mail].'

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

console.log(tree)

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

console.log(out)

Now, running node example yields:

{
  type: 'root',
  children: [
    {
      type: 'paragraph',
      children: [
        {
          type: 'link',
          title: null,
          url: 'http://www.example.com',
          children: [{type: 'text', value: 'www.example.com'}]
        },
        {type: 'text', value: ', '},
        {
          type: 'link',
          title: null,
          url: 'https://example.com',
          children: [{type: 'text', value: 'https://example.com'}]
        },
        {type: 'text', value: ', and '},
        {
          type: 'link',
          title: null,
          url: 'mailto:[e-mail]',
          children: [{type: 'text', value: '[e-mail]'}]
        },
        {type: 'text', value: '.'}
      ]
    }
  ]
}

[www.example.com](http://www.example.com), <https://example.com>, and <[e-mail]>.
