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:
- A URL template where
%sis replaced with the username (required) - A regular expression to parse and validate the username (optional - defaults to
'/^[A-Za-z0-9_]+(?!\w)/')
Note that @mention-style linking doesn’t actually require you to add the extension - just the InlineParser of your choice.
