THIS EXTENSION IS NO LONGER MAINTAINED, AND WE WILL NOT MAKE ANY NEW RELEASES. IF ANYONE WANTS TO TAKE OVER, PLEASE MAKE A FORK AND PUBLISH A NEW PACKAGE, AND WE'LL LINK TO THE NEW VERSION.
Twig Markdown extension provides a new filter and a tag to allow parsing of content as Markdown in Twig templates.
This extension could be integrated with several Markdown parser as it provides an interface, which allows you to customize your Markdown parser.
- michelf/php-markdown (+ MarkdownExtra)
- league/commonmark
- KnpLabs/php-github-api
- erusev/parsedown
- Filter support
{{ "# Heading Level 1"|markdown }} - Tag support
{% markdown %}{% endmarkdown %}
When used as a tag, the indentation level of the first line sets the default indentation level for the rest of the tag content. From this indentation level, all same indentation or outdented levels text will be transformed as regular text.
This feature allows you to write your Markdown content at any indentation level without caring of Markdown internal transformation:
<div>
<h1 class="someClass">{{ title }}</h1>
{% markdown %}
This is a list that is indented to match the context around the markdown tag:
* List item 1
* List item 2
* Sub List Item
* Sub Sub List Item
The following block will be transformed as code, as it is indented more than the
surrounding content:
$code = "good";
{% endmarkdown %}
</div>Run the composer command to install the latest stable version:
composer require aptoma/twig-markdownOr update your composer.json:
{
"require": {
"aptoma/twig-markdown": "~3.0"
}
}You can choose to provide your own Markdown engine, although we recommend using michelf/php-markdown:
composer require michelf/php-markdown ~1.8{
"require": {
"michelf/php-markdown": "~1.8"
}
}You may also use the PHP League CommonMark engine:
composer require league/commonmark ~0.19{
"require": {
"league/commonmark": "~0.19"
}
}The Twig extension provides the markdown tag and filter support.
Assuming that you are using composer autoloading, add the extension to the Twig environment:
use Aptoma\Twig\Extension\MarkdownExtension;
use Aptoma\Twig\Extension\MarkdownEngine;
$engine = new MarkdownEngine\MichelfMarkdownEngine();
$twig->addExtension(new MarkdownExtension($engine));The Twig token parser provides the markdown tag only!
use Aptoma\Twig\TokenParser\MarkdownTokenParser;
$twig->addTokenParser(new MarkdownTokenParser());To use this extension in a Symfony 3/4 app (including Pimcore), add the following snippet to your app's app/config/services.yml file:
services:
# ...
markdown.engine:
class: Aptoma\Twig\Extension\MarkdownEngine\MichelfMarkdownEngine
twig.markdown:
class: Aptoma\Twig\Extension\MarkdownExtension
arguments: ['@markdown.engine']
tags:
- { name: twig.extension }MarkdownEngine\GitHubMarkdownEngine provides an interface to GitHub's markdown engine using their public API via KnpLabs\php-github-api. To reduce API calls, rendered documents are hashed and cached in the filesystem. You can pass a GitHub repository and the path to be used for caching to the constructor:
use Aptoma\Twig\Extension\MarkdownEngine;
$engine = new MarkdownEngine\GitHubMarkdownEngine(
'aptoma/twig-markdown', // The GitHub repository to use as a context
true, // Whether to use GitHub's Flavored Markdown (GFM)
'/tmp/markdown-cache', // Path on filesystem to store rendered documents
);In order to authenticate the API client (for instance), it's possible to pass an own instance of \GitHub\Client instead of letting the engine create one itself:
$client = new \Github\Client;
$client->authenticate('GITHUB_CLIENT_ID', 'GITHUB_CLIENT_SECRET', \Github\Client::AUTH_URL_CLIENT_ID);
$engine = new MarkdownEngine\GitHubMarkdownEngine('aptoma/twig-markdown', true, '/tmp/markdown-cache', $client);If you want to use a different Markdown parser, you need to create an adapter
that implements Aptoma\Twig\Extension\MarkdownEngineInterface.php. Have
a look at Aptoma\Twig\Extension\MarkdownEngine\MichelfMarkdownEngine for an
example.
