Simplify if (x) Some(y) else None?

This common pattern feels a bit verbose:

else None

I was thinking of using a function to simplify:

Answer 1

You can use the PartialFunction companion object and condOpt:

PartialFunction.condOpt(condition) {case true => result}

Usage:

 scala> PartialFunction.condOpt(false) {case true => 42}
 res0: Option[Int] = None

 scala> PartialFunction.condOpt(true) {case true => 42}
 res1: Option[Int] = Some(42)
