@Dennis 2 things. 1) Can you pull Deorst, and 2) I'm planning/designing a 3D language, where different levels are represented as different files. If I were to get it on TIO, how much would that inconvenience/need to change TIO in order to make it work? I just want to know, to see if I should make a wrapper for it or not, so that it makes multiple files able to be entered as a single "file", so to speak.
Options affect the interpreter itself and aren't usually seen by the program. They're generally placed before the filename while arguments are placed after it.
@cairdcoinheringaahing Indeed. Syncing. Btw I'd recommend printing error messages to STDERR. I'd also print at least one level of traceback, but that's just me.
