Fatdown, a Markdown bundle that doesn't suck too bad

Fatdown is a bundle based on the Litedown plugin which supports most of Markdown's features, plus the MediaEmbed and FancyPants plugins for media embedding and enhanced typography.


You can try the real-time JavaScript demo, or you can compare Fatdown to various Markdown implementations via the wonderful Babelmark 2.


use s9e\TextFormatter\Bundles\Fatdown as TextFormatter;

$text = '**Fatdown** implements a Markdown-like syntax plus extra Stuff(tm).';
$xml  = TextFormatter::parse($text);
$html = TextFormatter::render($xml);

echo $html;
<p><strong>Fatdown</strong> implements a Markdown-like syntax plus extra Stuff™.</p>

Why Fatdown doesn't suck

Unlike the original Markdown, Fatdown's HTML support does not leave you wide open to XSS. Markdown is designed for publishers, not user input.

use s9e\TextFormatter\Bundles\Fatdown as TextFormatter;

$text = '<img src="" onerror="alert(1)"/>';
$xml  = TextFormatter::parse($text);
$html = TextFormatter::render($xml);

echo $html;
<p><img src=""></p>
