Appretiate you solving this one. I thought that nobody would ever do that honestly. Initially I thought about doing full blown stack based parsing, but couldnt wrap my head around it, so this is the simplified version of what I originally planned. My code even longer than yours as far as I can tell. I used a transpiler, which I wrote myself and all the macros I also wrote myself, so the code isnt the most efficient either. But it works and that's the main concern for any brainfuck program anyway.
