DEPRECATED
----------

[](#deprecated)

**This extension has been deprecated**. All of its functionality now exists in [`league/commonmark`](https://github.com/thephpleague/commonmark) 1.3+. You can either register the various extensions individually or use the `GithubFlavoredMarkdownExtension` to get full GFM functionality, so you should upgrade to that version of `league/commonmark` and use that instead of this one.

Overview
--------

[](#overview)

**league/commonmark-extras** is a collection of useful GFM extensions and utilities for the [league/commonmark](https://github.com/thephpleague/commonmark) project.

Adding this extension to your project will automatically register these sub-extensions:

Via Composer

```
$ composer require league/commonmark-extras
```

Usage
-----

[](#usage)

This can be added to any new `Environment`:

```
use League\CommonMark\CommonMarkConverter;
use League\CommonMark\Environment;
use League\CommonMark\Extras\CommonMarkExtrasExtension;

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

// REGISTER THIS EXTENSION HERE
$environment->addExtension(new CommonMarkExtrasExtension());

// Define your configuration:
$config = [];

// Now that the `Environment` is configured we can create the converter engine:
$converter = new CommonMarkConverter($config, $environment);

// Go forth and convert you some Markdown!
echo $converter->convertToHtml('# Hello World!');
```
