Is there an easy to to get the `Class`/`KClass` object of a top-level .kt file?

[Kirill Grouchnikov]

What's a top level file? What if it only has functions? What if it has multiple classes in it?

[Tianyu Zhu]

Suppose you declare a file named Util.kt with

fun foo() { ... }
fun bar() { ... }

In Java you'd be able to access these by writing

UtilKt.foo()

And you'd also be able to get the class:

UtilKt.class

Can I do the same in Kotlin?

[Tianyu Zhu]

I understand that this isn't appropriate for other backends... but I'm surprised I can't do this even specifically for Kotlin/JVM

[Joffrey]

I guess the wrapping class only exists so that Java can use such declarations, but is not supposed to exist from Kotlin's point of view. What is your ultimate goal here? What do you want to achieve with this class instance?

[Tianyu Zhu]

I would like to list all of the utility functions in UtilKt.class reflectively, e.g.

UtilKt::class.declaredFunctions

[Scott Kruse]

Put them in a kotlin class?

[ephemient]

not even

Class.forName("UtilKt").kotlin.declaredFunctions

will work, as "UtilKt" is not a Kotlin class, it is a Kotlin file facade class

but it doesn't look like there's any plans for them

Thank you! I've bookmaked those issues for now 🙂
