just updated to the latest IDE version and @JsPlainObject still does not seem to be supported by K2 mode; even worse, they show up as unused and IntelliJ removes these imports; any information on how Kotlin compiler plugin integration is supposed to be integrated?

[Edoardo Luppi]

It's probably a missing frontend feature. Better report it

[Bernhard]

it should work out of the box with k2, right?

[Edoardo Luppi]

Not really. In the sense that you can implement all of it for the compiler backend, but if the frontend doesn't know about it, you'll see errors in IJ.

Let me have a look at the sources

https://github.com/JetBrains/kotlin/tree/1760c705dc24c81d7cf455e5cbd71f21f7b3a03e/[…]/js-plain-objects.k2/src/org/jetbrains/kotlinx/jso/compiler/fir
Looks like there is something for the frontend

[Edoardo Luppi]

So two things might be going wrong:
• frontend part of the plugin missing something
• analysis API missing something

[Edoardo Luppi]

I'd say report it with a minimal example

[Bernhard]

ok, thank you 🙂

[Edoardo Luppi]

Analysis API has issues with externals btw.
In my experiments every external is marked as unused.

[Edoardo Luppi]

What happens when you apply @JsPlainObject is:

external interface Test {
  val str: String

  companion object {
    inline operator fun invoke(str: String) { ... }
  }
}
