I'd like to implement the equivalent of an "around advice" aspect for some auditing functions. Is KSP a reasonable tool to use? If yes, are there any examples doing something similar that I can look at?

what is “around advice”?

Basically a wrapper around a delegate. The wrapper can take actions before and after the delegate executes, or shortcut execution, etc. Mine will look basically like this: Given an `originalFun`:

fun originalWrapperFun() {
  return try {
    originalFun().also {
      doSomething()
    }
  } catch (e: Exception) {
    doSomethingElse()
    throw e
  }
}

Are you generating that in a new class? If yes, KSP is fine. If no, KSP will not work.

I was hoping to avoid that, as that means calling code has to change. However, I suppose I could update the callers to refer to the generated classes.

Not intended as an advertisement, but Micronaut supports kotlin and AOP

If generating in a new file is fine to you, you can achieve your goal by generating your wrapper in a new file with KSP. Alternatively you case looks like can just be a handy inline function.

Yeah I'm going with an inline function for now. Thx!
