CommonMark Attributes Extension

, _(*1)

The Attributes extension adds a syntax to define attributes on the various HTML elements in markdown’s output., _(*2)

DEPRECATED

This extension has been deprecated. All of its functionality now exists in league/commonmark 1.5+ under the League\CommonMark\Extension\Attributes namespace, so you should upgrade to that version and use that bundled extension instead of this one., _(*3)

Installation

This project can be installed via Composer:, _(*4)

composer require webuni/commonmark-attributes-extension

Usage

use League\CommonMark\Converter;
use League\CommonMark\DocParser;
use League\CommonMark\Environment;
use League\CommonMark\HtmlRenderer;
use Webuni\CommonMark\AttributesExtension\AttributesExtension;

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

$converter = new Converter(new DocParser($environment), new HtmlRenderer($environment));

echo $converter->convertToHtml('# Hello World!');

Syntax

The basic syntax was inspired by Kramdown‘s Attribute Lists feature., _(*5)

You can assign any attribute to a block-level element. Just directly prepend or follow the block with a block inline attribute list. That consists of a left curly brace, optionally followed by a colon, the attribute definitions and a right curly brace:, _(*6)

> A nice blockquote
{: title="Blockquote title"}

{#id .class}
## Header

As with a block-level element you can assign any attribute to a span-level elements using a span inline attribute list, that has the same syntax and must immediately follow the span-level element:, _(*7)

This is *red*{style="color: red"}.
