Ah, we did not code the wikitext or CSS/JS/Lua highlighters from scratch - they're based on pre-existing work (I suggest checking our codebase if you want more specifics). Much of our work is in making them work on Wikia (with all of our differences and special features), rather than on the underlying highlighting code.
