#programming help

See, from what I can find, nobody has had a great solution to getting a program to do autosplitting for speedrun timers on Linux for Celeste. Or at least, if they have, they're not telling me.

I'd like to use LibreSplit, but I don't know Lua. If I did, this might be easier. If someone's able to help me, that'd be super awesome! I'd get to learn something, and I'd gain a valuable tool for getting faster at Celeste Any%. My current goal is to get down to 40 minutes.

Here's the documentation for LibreSplit, if anyone want to take a peek:

I was relegated the legacy code of a game, which has a lot of problems. The owner burnt out from the technical debt, and I have no idea how to tackle it properly since I was given the code (2 years ago, maybe more)

The code is all in 1 file. From memory, there are at least 30k LOC. The methods are not documented, and several arguments can be of two classes which are not under the same polymorphism, and really shouldn't be (a character and a location).

I don't know what I should do first: split the classes into files but keep shared methods, split classes and shared methods, documents all the file, migrate to better libraries, bugfix everything I can, maybe a secret option?

As some of you know, there exists a downloadable version of a sylladex, it isn't as cool as sylladices are in the actual webcomic, but you can use it as an equivalent to 'your recent files' on your desktop. My trouble is (although don't get me wrong, I enjoy it) there are many modi featured in homestuck which don't exist in the aforementioned pc version I've been talking about here.
