A modern programming language that makes developers happier.

kotlinlang

I have my own FIR-based parser, and during the upgrade from 2.1.10 to 2.1.20 I'm losing my ability to read function parameter names. Before I was pulling it out of the customAnnotations, but that is now empty on the ConeLikeClassType (or whatever it's called), as well as the entire type attributes being empty. I started trying to look at the regular compiler but can't find anything relevant.

Parameter name moved to a new attribute: `ParameterNameTypeAttribute`. Should be able to use <https://github.com/JetBrains/kotlin/blob/master/compiler/fir/tree/src/org/jetbrains/kotlin/fir/types/ParameterNameTypeAttribute.kt#L78-L82|one of these utilities> to get access to the name again.

You mention the types attributes being empty; is that to say that `CustomAnnotationTypeAttribute` has no annotations? Or that there are no cone attributes at all?

Ah, yep. I got it now. Was half user-error and half... more user-error :simple_smile:

Those helpers are very convenient. Thanks!
