Well you’re writing a Compiler with extra features to tell you where compilation failed but without actually executing the code. If the language you are trying to implement has defined a BNF for its language its quite doable and depending on the features you want to implement almost easy. There are BNF interpreters and chumsky e.g. is close to reading like a BNF. But if you’re building a language where you gotta find out the rules yourself it can take a while and finding all the edgecases can be a problem… But the project is big enough that most probably don’t finish theirs
That its producer has gone bancrupt they have absolutely lived the enshittyfication while doing the settings in their custom Android and I am currently on the last supported android version (12) which will probably go unsupported soon-ish and the company I got the phone from has sold so few that the definitely better alternatives (Lineage, etc) don’t have any reports of people who have done it with my device or even a tutorial. And reading into flashing it on an unsupported device is a rabbithole I currently don’t want to spend time with. And if I fuck up I can’t even write the company to fix it for me or smth like that…
