Snapblocks is an extension to display blocks from the Snap! programming language created by Jens Mönig and Brian Harvey in wiki articles. It is also a fork of the ScratchBlocks extension.

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

Installation

• Download and place the file(s) in a directory called Snapblocks in your extensions/ folder.
• Add the following code at the bottom of your LocalSettings.php file:

  wfLoadExtension( 'Snapblocks' );
  

• Configure languages if needed.
•  Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.

Configuration

By default, only English Snap! blocks are rendered. Add more languages like so:

Note: currently translations are somewhat broken, and only include Scratch primitives. Note that the TW is preceded by an underscore, not a hyphen. This variable is accessible through JS mw.config.get("wgSnapBlocksLangs")

Usage

There are three ways to create a snippet of Snap! blocks, which are nearly identical.

• Use <snapblocks> before and after your code to create a block level element displaying Snap code.
• Use <scratchblocks> before and after your code to create a block level element displaying Snap! code. This is kept from the ScratchBlocks extension, in order to make transitioning to Snapblocks easier.
• To create an inline-block element (that will show in the middle of the paragraph), enclose the code in <sb> tags.

<snapblocks>
repeat (5) {
  move (10) steps
}
say [Done!]
</snapblocks>

You can map over a list in Snap! with the <sb>(map (() @addInput) over @list)</sb> block.

All three tags take a version attribute, whose default value is snap. If specified as 2 or 3, the tag will render its blocks in Scratch 2.0 or 3.0 style respectively. You can also specify hc-3 for the Scratch 3.0 high contrast style, and snap-flat for the Snap! flat design.
