This actually is a great idea!

In the end the MediaWiki syntax is some kind of source code after all (even if it's syntax is really easy) and syntax higlighting is always a huge help for reading through source code of all kinds.

If the built-in editor would contain some basic syntax highlighting this would help new editor to learn wiki syntax and made editing for experienced users more comfortable.

I already found a JavaScript with such functionality (https://www.mediawiki.org/wiki/User:Remember_the_dot/Syntax_highlighter) and I don't see any reason why something like this shouldn't be included in the MediaWiki software (and on all Wikimedia projects) by default.

What's the status of this?

I am developing the CodeMirror extension [1] that highlights the wiki markup in <textarea>. It is not ready for real usage yet, but you can already see how it work [2] and help me to make it more usable.

Also I'm going to implement a function described in bug 13302.

Somehow these topics are avoided for a long time therefore I doubt that there is any way to integrate this solution into mediawiki software.

In any case, I'm going to continue working on this extension, and if there is someone interested in this solution, let me know.
