I am getting an empty list when I call function.contextReceivers where function is KtNamedFunction with Kotlin 1.7.10. Is there any way to get the list of context receivers?

[Javier]

Tried 1.7.20 beta and same issue

[denis.zharkov]

It should not be empty in case the function has context receivers specified.
Otherwise other part of the feature wouldn’t just work.

[Javier]

The use case can be weird, it was a test for a formatter, maybe the problem is I need to enable context receivers in tests or something so (the tests are just strings assertions).

[denis.zharkov]

maybe the problem is I need to enable context receivers in tests

For that, actually you don’t need to enable anything in the test
I would assume, there are just no context receivers on the function, probably it’s the wrong instance or something like that

[Javier]

not sure what I am doing wrong

[denis.zharkov]

Probably it’s worth trying to debug what children the PSI node of function actually have
Like does it have a CONTEXT_RECEIVER_LIST

[Javier]

I have tried adding other things like <T> and they are there

[Javier]

looks like they are not detected, if I add a <T>, it is appearing there too as third element

[denis.zharkov]

Really strange. Then I would debug if we really parse it at org.jetbrains.kotlin.parsing.KotlinParsing#parseContextReceiverList

[Javier]

the debugger doesn't enter in that function

[denis.zharkov]

But how does it behave at parseTopLevelDeclaration ?
At the

if (at(CONTEXT_KEYWORD)) {
    parseContextReceiverList();
}

[Javier]

the debugger doesn't even appear outside if 🤔

[Javier]

I put a breakpoint in all of those lines

[Javier]

looks like the debugger doesn't work there

[Javier]

or it is not entering

[denis.zharkov]

It’s really hard to tell, but it seems that you’ve got some semi-correct env where the parsing classes come from the outdated version of compiler or something like this 😞

[Javier]

Not sure, I can push to a branch and share a repo for you

Sorry, I’m not sure I will be able to dig into this issue deeper, soon.
Only can suggest to somehow make sure that org.jetbrains.kotlin.parsing.KotlinParsing used at runtime is really up-to-date (i.e., it actually has parseContextReceiverList method) or somehow figure out how to debug it properly.

[Javier]

the debugger is entering in the KotlinParsing class, but not in the parseFile method

[Javier]

yeah, there is something weird now
