Extension:Snapblocks

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.

• 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.
• Yes Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.

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

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

This variable is accessible through JS: mw.config.get("wgSnapBlocksLangs")

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

• Use ‎<snapblocks>...‎</snapblocks> to create a block level element displaying Snap code.
• Use ‎<scratchblocks>...‎</scratchblocks> 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>...‎</sb> tags.

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

You can map over a list in Snap! with a <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.
