I really wrote this for my own use but decided to put it out there. Seems to work okay with some code and certainly, at the time, it worked fine for ALL my own pico-8 code (but I do code in a very particular, quite simple, way). Weird that it doesn't cope with block comments though. In saying that, I always end mine "]]--" which my code seems to handle fine. Didn't realise you could omit the "--".
