Syntax highlighting (based on CodeMirror) is a beta feature on all left-to-right wikis: https://meta.wikimedia.org/wiki/Community_Tech/Wikitext_editor_syntax_highli...

(It'll come to right-to-left wikis as soon as the RTL problems have been fixed.)

There's not going to a big MassMessage to all the wikis about this, but if you think it'll be helpful, please spread the word in your community, on your local Village Pump etc.
