moxio/commonmark-ext-definition-list

Extension for the league/commonmark Markdown parser to support definition lists.

Uses unofficial markdown syntax based on the syntax supported by PHP Markdown Extra, Pandoc and markdown-it. See the section Syntax below for details.

Requirements

This library requires PHP version 7.4 or higher and a 1.x release of league/commonmark.

Installation

Install as a dependency using composer:

$ composer require --dev moxio/commonmark-ext-definition-list

Usage

Add DefinitionListExtension as an extension to your CommonMark environment instance and you're good to go:

use League\CommonMark\CommonMarkConverter;
use League\CommonMark\Environment;
use Moxio\CommonMark\Extension\DefinitionList\DefinitionListExtension;

$environment = Environment::createCommonMarkEnvironment();
$environment->addExtension(new DefinitionListExtension());

// Use $environment when building your CommonMarkConverter
$converter = new CommonMarkConverter([], $environment);
echo $converter->convertToHtml('
Term 1
: Definition of term 1.

Term 2
: Definition of term 2.
');

See the CommonMark documentation for more information about using extensions.

Syntax

The supported markdown syntax is based on the one used by PHP Markdown Extra, Pandoc and markdown-it. Since there are subtle differences between the syntaxes understood by these libraries and there is no formally defined standard, 100% compatibility with any of the aforementioned libraries cannot be guaranteed. The use of the tilde (~) as a definition list marker (as understood by Pandoc) is also supported.

A simple example:

Apple
:   Pomaceous fruit of plants of the genus Malus in
the family Rosaceae.

Orange
:   The fruit of an evergreen tree of the genus Citrus.

The will yield HTML output like:

<dl>
  <dt>Apple</dt>
  <dd>Pomaceous fruit of plants of the genus Malus in
the family Rosaceae.</dd>
  <dt>Orange</dt>
  <dd>The fruit of an evergreen tree of the genus Citrus.</dd>
</dl>

A more complex example:

Term 1

:   This is a definition with two paragraphs. Lorem ipsum
    dolor sit amet, consectetuer adipiscing elit. Aliquam
    hendrerit mi posuere lectus.

    Vestibulum enim wisi, viverra nec, fringilla in, laoreet
    vitae, risus.

:   Second definition for term 1, also wrapped in a paragraph
    because of the blank line preceding it.

Term 2

:   This definition has a code block, a blockquote and a list.

        code block.

    > block quote
    > on two lines.

    1.  first list item
    2.  second list item
