markdown_to_htmlΒΆ

New in version 2.12: The markdown_to_html filter was added in Twig 2.12.

The markdown_to_html filter converts a block of Markdown to HTML:

1
2
3
4
5
6
{% apply markdown_to_html %}
Title
======

Hello!
{% endapply %}

Note that you can indent the Markdown content as leading whitespaces will be removed consistently before conversion:

1
2
3
4
5
6
{% apply markdown_to_html %}
    Title
    ======

    Hello!
{% endapply %}

You can also use the filter on an included file:

1
{{ include('some_template.markdown.twig')|markdown_to_html }}

Note

The markdown_to_html filter is part of the MarkdownExtension which is not installed by default. Install it first:

1
$ composer req twig/markdown-extra

Then, use the twig/extra-bundle on Symfony projects or add the extension explictly on the Twig environment:

use Twig\Extra\Markdown\MarkdownMarkdownExtension;

$twig = new \Twig\Environment(...);
$twig->addExtension(new MarkdownExtension());

If you are not using Symfony, you must also register the extension runtime:

 1
 2
 3
 4
 5
 6
 7
 8
 9

11
use Twig\Extra\Markdown\DefaultMarkdown;
use Twig\Extra\Markdown\MarkdownRuntime;
use Twig\RuntimeLoader\RuntimeLoaderInterface;

$twig->addRuntimeLoader(new class implements RuntimeLoaderInterface {
    public function load($class) {
        if (MarkdownRuntime::class === $class) {
            return new MarkdownRuntime(new DefaultMarkdown());
        }
    }
});
