ScratchBlocks is an extension to display Scratch, a programming language created by MIT, in wiki blocks.

Installation

Download and place the file(s) in a directory called ScratchBlocks in your extensions/ folder.
Add the following code at the bottom of your LocalSettings.php file:
```
wfLoadExtension( 'ScratchBlocks' );
```
Configure languages if needed.
Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.

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

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

Note that the TW is preceded by an underscore, not a hyphen. This variable is accessible through JS mw.config.get("wgScratchBlocks4Langs")

There are two ways to create a snippet of Scratch blocks, which are nearly identical.

Use <scratchblocks> before and after your code to create a block level element displaying Scratch code.
To create an inline-block element (that will show in the middle of the paragraph), enclose the code in <sb> tags.

<scratchblocks>
repeat (5)
  move (10) steps
end
say [Done!]
</scratchblocks>

You can repeat Scratch code in a <sb>forever</sb> loop!

Both tags take a version attribute, whose default value is 3. If specified as 2, the tag will render its blocks in Scratch 2.0 style.
