Could we hope for annotation processing one day in non-jvm projects? Is that too far fetched?

[ian.shaun.thomas]

Good question. Annotation processing does work with the compiler but I'm not sure how extensible that is. For instance you can use @Jvm* annotations

Guess IR compiler plugins are MPP way of annotation processing

[galex]

@olonho Do you have any example of generating complete classes (hopefully with KotlinPoet) and using it in a project?

[svyatoslav.scherbina]

See kotlinx.serialization compiler plugin. Here is IR part: https://github.com/JetBrains/kotlin/tree/master/plugins/kotlin-serialization/kotlin-serialization-compiler/src/org/jetbrains/kotlinx/serialization/compiler/backend/ir

Thanks, really interesting.

Once code is created and generated based on a compiler plugin, does the class exist on the classpath and the dev can just import it?

[svyatoslav.scherbina]

Importing is made possible by another part of the plugin which injects corresponding declarations to the frontend.
IR is for the compiler backend only.

Would that be an IntelliJ plugin or a gradle one?

[galex]

I guess I have examples of that in kotlinx-serialization as well since we can call directly serializer() ?

Technically it is compiler plugin.

Yes, kotlinx.serialization compiler plugin should have examples of that.
