OK I see, I sometimes put multiple spaces for data alignment (it takes more space but I write the code on the assumption I’ll minify it).
Currently I’m using a custom branch of luamin for my minifications, it’s really good with most normal Lua code. It uses actual parsing which allows it to spot invalid code. But the downside is that it doesn’t recognize the PICO-8 specific patterns like 1-line if() (and some binary operators despite being part of vanilla Lua) so it would error on most code actually written by PICO-8 devs… Requiring me to write fully expanded statements everywhere to avoid errors, then minify them (final result is still good! But I wonder if I couldn’t grasp a few characters here and there with a truly “PICO-8 aware” minifier.
