Autolink Extension

(Note: this extension is included by default within the GFM extension)

The AutolinkExtension adds GFM-style autolinking. It automatically links URLs and email addresses even when the CommonMark <...> autolink syntax is not used.

It also provides a parser to autolink @mentions to Twitter, GitHub, or any custom service you wish, though this is disabled by default.

Installation

This extension is bundled with league/commonmark. This library can be installed via Composer:

composer require league/commonmark

See the installation section for more details.

Usage

Configure your Environment as usual and simply add the AutolinkExtension provided by this package:

use League\CommonMark\CommonMarkConverter;
use League\CommonMark\Environment;
use League\CommonMark\Extension\Autolink\AutolinkExtension;

// Obtain a pre-configured Environment with all the CommonMark parsers/renderers ready-to-go
$environment = Environment::createCommonMarkEnvironment();

// Add this extension
$environment->addExtension(new AutolinkExtension());

// Instantiate the converter engine and start converting some Markdown!
$converter = new CommonMarkConverter([], $environment);
echo $converter->convertToHtml('I successfully installed the https://github.com/thephpleague/commonmark project with the Autolink extension!');

@mention-style Autolinking

This extension also provides functionality to automatically link “mentions” like @colinodell to Twitter, GitHub, or any other site of your choice!

For Twitter:

use League\CommonMark\Environment;
use League\CommonMark\Extension\Autolink\InlineMentionParser;

$environment = Environment::createCommonMarkEnvironment();
$environment->addInlineParser(InlineMentionParser::createTwitterHandleParser());

// TODO: Instantiate your converter and convert some Markdown

For GitHub:

use League\CommonMark\Environment;
use League\CommonMark\Extension\Autolink\InlineMentionParser;

$environment = Environment::createCommonMarkEnvironment();
$environment->addInlineParser(InlineMentionParser::createGithubHandleParser());

// TODO: Instantiate your converter and convert some Markdown

Or configure your own custom one:

use League\CommonMark\Environment;
use League\CommonMark\Extension\Autolink\InlineMentionParser;

$environment = Environment::createCommonMarkEnvironment();
$environment->addInlineParser(new InlineMentionParser('https://www.example.com/users/%s/profile'));

// TODO: Instantiate your converter and convert some Markdown

When creating your own, you can provide two parameters to the constructor:

Note that @mention-style linking doesn’t actually require you to add the extension - just the InlineParser of your choice.
