Question

hm not sure if it s a bug or not but I don t get a primary constructor if I don t explicitly define one Imo it would be easier if it returned a no arg constructor in that case Don t think there s any value in differentiating between the two right ```class Foo gt primaryConstructor is null class Bar gt primaryConstructor is not null```

Currently KSP models this directly after the grammar structure Adding a dummy constructor should be possible On the other hand people may sometimes want to tell the difference

Guess it depends on how much sugar you see here with omitting the constructor explicitly Might be biased but the java annotation processor api does include it Imo seems pretty similar to <https github com android kotlin issues 19>

and another one properties in interfaces are implicitly abstract but `modifiers` doesn t include abstract

evant · Answer

Actually now that I ve thought about it more I think modeling directly after the grammar structure is the wrong way to go This forces processors to build in their own logic to match the semantics of kotlin language For example if I want to work on public methods I want all methods that are public not methods that literally have the public modifier defined Telling the difference actually sounds dangerous here since it means semantically identical programs could behave differently under the presence of a processor which seems like a very bad idea to me

Yes having everyone implement their helpers isn t a good idea We plan to build helpers for common use cases For this particular case public we have a helper already <https github com android kotlin blob ksp libraries tools kotlin symbol processing api src org jetbrains kotlin ksp utils kt L52> and we are planning to provide more

I created an issue for those implicit properties modifiers elements <https github com android kotlin issues 25> Please let us know more how we can make KSP better

Interestingly enough I tried to implement this myself but I don t think I can there doesn t seem to be a way to tell if a function has a body or not
