Hi, If I have a package (*.kt file) and have only functions declared in it (not any class besides package itself) - is it possible by using reflection to obtain the list of those declared functions? I have tried to do something like this -

val o = object{}
val mm = o.javaClass.declaredMethods

and

val mm = o::class
  val ff = mm.declaredMemberFunctions

but it doesn't return anything. is it possible at all? if so, would the function modifier affect this search (private, public, etc)?

Unfortunately this is not yet natively supported by Kotlin reflection: https://youtrack.jetbrains.com/issue/KT-16479

At the moment, you can use Java reflection and use `.kotlinFunction`/`.kotlinProperty` to map Java reflection objects to Kotlin:

// FILE: test.kt

import kotlin.reflect.jvm.*

fun foo() = "OK"

fun main() {
    val functions = (object {}).javaClass.enclosingClass.declaredMethods
    val foo = functions.single { it.name == "foo" }.kotlinFunction!!
    println(foo.call()) // OK
}

Thank you, @udalov. I have managed to use java reflection before your post here like this (from within main()) -

::main.javaMethod!!.declaringClass.declaredMethods.filter { it.name.startsWith("foo") }.map {it-> it.name}
