Even simpler is you go the colorforth route, part of the source code is "pre parsed" by the editor, a prefix byte is added to each word (which is shown as different colors), then a simple dispatch loop with that prefix as a sort of opcode.

This feels like a precursor to the project I'm doing, which I us to make an editor whose state and output are expressed as such "pre-parsed" syntax trees. I'm trying to make mine fully language agnostic though
