This is the documentation for the upcoming version 2.0. This is a work in progress

Inlines Only Extension

This extension configures the parser to only render inline elements - no paragraph tags, headers, code blocks, etc. This makes it perfect for commenting systems where you only want users having bold, italics, links, etc.


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.


Although you normally add extra extensions along with the default CommonMark Core extension, we’re not going to do that here, because this is essentially a slimmed-down version of the core extension:

use League\CommonMark\CommonMarkConverter;
use League\CommonMark\Environment\Environment;
use League\CommonMark\Extension\InlinesOnly\InlinesOnlyExtension;

// Create a new, empty environment
$environment = new Environment();

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

// Instantiate the converter engine and start converting some Markdown!
$converter = new CommonMarkConverter($config, $environment);
echo $converter->convertToHtml('**Hello World!**');
