@turansky I was trying to use seskar to generate enum constants as unions. Will it be possible to export the resulting declaration in the typescript file generated using generateTypeScriptDefinitions()? I guess the limitation here is that the compiler plugin cannot plug into the generation of the typescript definition 🤔

[turansky]

Probably it can be implemented via synthetic @file:JsModule("./additional-ts-file")

[turansky]

If such annotation on file with union works fine and produces import in .d.ts file - it can be used by Seskar

as far as I can see it doesn't, I can't get the class to appear in the output js even with JsModule

[turansky]

Missed @JsExport?

If I add the @JsExport to the sealed external interface I get this error:

This is what made me initially think it couldn't be exported

:(

I guess this is the line that fails when the companion object is processed:

irGetter = context.mapping.objectToGetInstanceFunction[klass]!!
