Is it possible, from a compiler plugin, to get the original source code for the call site of a function? Is this something being considered/possible for the new IR compiler plugins? I've been poking around in the Kotlin repository trying to figure out if an idea I have for a plugin is even possible. I found org.jetbrains.kotlin.ir.SourceManager but I'm not sure if that can be used to read the source file given an IrCall.

The specific idea I have is a compiler plugin to enable power assertions similar to Groovy: https://groovy-lang.org/testing.html#_power_assertions

There seemed to be some discussion on this a few years ago but I haven't really seen anything since: https://discuss.kotlinlang.org/t/support-for-groovy-style-power-assertion-in-kotlin/427

Maybe you could use https://github.com/arrow-kt/arrow-meta and rewrite the source code of your assert function

Woah, that’s super cool

@bnorm A little bit late to the party, but you can use IrDeclaration.descriptor.findPsi() to get psi, which contains all the text with offsets.
