How do you reference another function (or wrap it in a lambda) in IR? I have a

fun hello(who: String) = "Hello, $who!"

as a

IrSimpleFunction

. I need to pass this to a fun

process(function: (String) -> String)

, but I’m confused as to how to pass my function as a value argument to another. To be clear, in source code I’d do process(::hello) or process { hello(it) }.

You can take a look at

IrFunctionReference

, which backs up

::hello

syntax iirc

What I usually do is to write it in Kotlin and use

IrModuleFragment.dump()

how the IR looks like. From there it is usually easy to find the IR calls to build the given part.

Thanks a lot guys. dump is super useful. I also went a long way by just looking at autocompletion, e.g.

ir*

functions in declaration builder, or ir factory. For some reason function references are not advertised there though
