Hi everyone I would like to try to work with the kotlin AST but I have no idea where to start. Do you have any suggestions / links?

I haven't done much of that, but you can maybe check out KSP (Kotlin Symbol Porcessing). Also you can ask #compiler or #ksp

Not everything you need to get started, but a helpful extra: I suggest cloning the Kotlin repository. Keeping the code for the AST on hand is super helpful.

Yeah, these are good approaches. Thank you, I'll check out them.
