fun x(a: String) {
    print(::a.name) // References to variables aren't supported yet.
}
val someVar = 1;
x(someVar) // ::a.name should be someVar

Is there a way to know the name of a property or a variable passed to the function by reflection?

Maybe something like this could help you:

fun x(a: String = "") {
    println(this::x.parameters.first().name)
}

x()
// prints: a

I.e. a reference to the function and then get its parameters, but then you must know the parameter's index (or just take the first like I did here)

[Erik]

Ah, I see you've edited your question and my answer is probably not what you're looking for

[aeruhxi]

Yeah, I guess there is no way, right?

[Erik]

I guess not.

It seems to me that if you need the name of something from outside of the function's scope, then you should pass that name in as a parameter. It's the outside scope that knows this name, after all. If there even is a name.

[Erik]

Because

val name = ""
x(name)

and

x("")

behave the same, but in your case you probably want different behaviour in x.

[aeruhxi]

Yeah. I guess I will pass from outside.
