A simple MediaWiki extension for rendering Snap! and Scratch Blocks. Supports MediaWiki 1.35+.

Transforms <snapblocks> <scratchblocks> tags inside wiki articles into <pre class="blocks"> in the HTML, which are then rendered to scratch blocks using CSS and JS included in the page. Inline blocks are rendered with <sb> tags, and become <code class="blocks"> tags.

Use version attribute to set the version. Valid values are, snap, snap-flat, 2, 3, and 3-hc.

Installation

$ cd extensions
$ git clone http://github.com/snap-blocks/mw-snapblocks

After cloning, add the line

wfLoadExtension( "mw-snapblocks" );

to your LocalSettings.php file. If you need to use languages besides English, add the following line (Japanese and Traditional Chinese used as an example):

$wgScratchBlocks4Langs = ['ja', 'zh_TW'];

Note that the TW is preceded by an underscore rather than a hyphen.

This variable is accessible through JavaScript via mw.config.get("wgSnapBlocksLangs").

Use $wgSnapBlocksBlockVersion to specify the default version. Valid options are, snap, snap-flat, 2, 3, and 3-hc.

There are some other options

$wgSnapBlocksWrap = true // Enable block wrapping. This is turned on by default (true).
$wgSnapBlocksWrapSize = 500 // Specify minimum width required for block wrapping. Set this to null for default width.
$wgSnapBlocksZebraColoring = true // Enable zebra coloring. This is turned on by default (true).
