For typical fullstack setup (common, js, jvm source sets) I would like to process common sources and generate new sources for all three targets. Should I use three different processors or there is some way to know which source set is being processed?

I suppose this <https://github.com/google/ksp/issues/965> and <https://github.com/google/ksp/pull/1021> is what I want.

That's correct. I'm currently thinking about a possible API, which should be convenient to use, yet cover all relevant use cases. I'm currently investigating possible use cases like processors which feature
• one set of generated files per source set (files are generated when their input source set is the current output source set),
• expect/actual code generation with an input source set containing annotations which then trigger generation of `expect` code on the same source set level and `actual` code on leaf (target) source sets.
If you'd like to, you could add your use case to <https://github.com/google/ksp/issues/965>. That would certainly help.
