Get Scala variable name at runtime

Question

Is it possible to get the name of a scala variable at runtime?

E.g. is it possible to write a function getIntVarName(variable: Int): String behaving as

Answer 1

You can use scala-nameof to get a variable name, function name, class member name, or type name. It happens at compile-time so there's no reflection involved and no runtime dependency needed.

val myInt = 3
assert("myInt" === nameOf(myInt))

will compile to:

val myInt = 3
assert("myInt" === "myInt")
