I have written this code
object Foo extends Enumeration {
val X = Value("X")
val Y = Value("Y")
}
val regex = """([A-Z]+)(\d+)""".r
val input = "ABC123"
input match {
case regex(x, num) if x == Foo.X.toString => // do something
case regex(x, num) if x == Foo.Y.toString => // do something
case _ => // throw error
}
This works but is a little too verbose. I tried to change it to
input match {
case regex(`Foo.X.toString`, num) => // do something
case regex(`Foo.Y.toString`, num) => // do something
case _ => // throw error
}
But this does not compile. Apartently those ``` work for "vals" but not for enumerations.

Use Enumeration inside of Regex pattern matching
