Thanks for the patch. It's integrated in several commits, ending in [0773c93d2db3].
I did have to reformat several of the lines because they went past 80 columns, feel free to verify that I didn't break anything. I did edit one line for correctness (`"Regex|Regex Match"` is in the wrong order since space matches the negative lookahead that follows). I spot-checked the other regexes and didn't find anything, but will try to give a full review later.
I think I found a bug in that `:::` is highlighted as a symbol rather than operator. Feel free to open another bug if that's the case, so we can track it.
