Hi! Is it possible to generate IrClass that is not associated with existing (source) code (in a parent-child relationship)? I want to use this class in multiple existing files on the IR level but:
• When I leave parent empty - class is not compiled
• When I associate it with existing code - IC errors occur while removing class parent declaration from the source code

Yes, it is possible. You can add it to one of the files in the IrModuleFragment. However, you won't be able to see it in the IDE or use it from other modules.

I know that it won't be visible and I don't need it. Adding it to the one of files in IrModuleFragment falls into second case - IC errors when file is removed.

[Damian Baczyński]

I just want to share IrClass between multiple IrFile s.

[Damian Baczyński]

So I kind of need it to be "independent" to avoid IC errors.

[Tóth István Zoltán]

Theoretically it's possible if you add a FIR plugin that creates a top-level declaration. But that's buggy and won't compile in multiplatform IIRC.

[Tóth István Zoltán]

Also, adding a fully independent class will result a lot of problems during incremental compilation.

Is generating new IrFile possible?

[Damian Baczyński]

I tried FIR and because of the bugs it's not really an option at the moment. I hoped there is any other solution.

[Tóth István Zoltán]

I have no experience with that (adding an IrFile). I tried to solve a similar problem for weeks, but then I just gave up and used a different structure built on existing declarations.

So it's seems that I have to stick to redundancy. I need this independent class to just optimize redundancy. Anyway, thank you for help!
