kotlinlang

Hello all, I’m currently playing with KotlinPoet on a jvm desktop app and I’m wondering if its possible to actually edit a existent class with it.

usecase: I’m attempting to build an app to bootstrap code for one of our features and it involves editing some classes

It doesn’t do any parsing, it just writes. You could use something like KSP to do some high-level parsing and then use kotlin poet to spit out auxiliary source code, or use a full-fledged compiler plugin to rewrite bytecode.

The problem with those alternatives is that it would change the way we code our feature. It is an option indeed.
Another option would be to call `toString()` from i.e. a TypeSpec and place it inside some file through IO apis, right?

Maybe something like what KtLint does would help? It has apis to modify the source, although they're pretty low-level
Edit: just read Jake's comment, it's basically PSI so the same thing
