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.


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.


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

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

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

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

// Set your configuration if needed
    // ...

// Instantiate the converter engine and start converting some Markdown!
$converter = new MarkdownConverter($environment);
echo $converter->convertToHtml('I successfully installed the project with the Autolink extension!');

@mention-style Autolinking

As of v1.5, mention autolinking is now handled by a separate Mention extension.
