With Scala 2.13 it will be possible to do it without macro with something like : 

  def show(p: Product): String =
    p.productElementNames.zip(p.productIterator)
     .map { case (name, value) => s"$name=$value" }
     .mkString(p.productPrefix + "(", ", ", ")")

pushed #117 PR with macro-free show method on case classes
