hot tip for editing

.def

files in IntelliJ: add

#language=c

before the

---

and IntelliJ will recognise it as C, and help out with highlighting, formatting, and auto completion

That should be added to all the examples like this one: https://kotlinlang.org/docs/native-c-interop.html#add-custom-declarations

Very surprised that the Kotlin team didn't mention this in a K/N issue ( https://youtrack.jetbrains.com/issue/KT-55030/Native-obscure-errors-when-passing-by-valu[…]on-with-nested-struct-with-bitfields-between-C-and-Kotlin ) that was encountered.

Unfortunately it doesn't seem to work for Objective-C with

#language=Objective-C

.

#language=C

is still better than without though.

We did not know about this feature either :D
