The showFieldNames parameter doesn't seem to do anything

[DCameronMauch]

scala> case class User(id: Int, name: String)
defined class User

scala> val bob: User = User(1, "Bob")
bob: User = User(1,Bob)

scala> pprint.pprintln(bob)
User(1, "Bob")

scala> pprint.pprintln(bob, showFieldNames = true)
User(1, "Bob")

scala> pprint.pprintln(bob, showFieldNames = false)
User(1, "Bob")

With the feature enabled, I expected something like User(id = 1, name = "Bob")

Ah, got the same problem, but then carefully read change notes.

You're probable using scala 2.12
Field name support works only for 2.13
