Does Scala have a library method to build Option-s that takes into account empty strings?

Question

I want to filter out empty strings to put them into an Option. So I quickly built this now:

def StrictOption(s: String) = s match {
  case s if s != null && s.trim.length() > 0 => Some(s)
  case _ => None
}

Question: is this maybe already somewhere in the standard library?

Answer 1

I don't think there's one single method in the standard library to do this, but you can do this much more tersely than your implementation.

Option(s).filter(_.trim.nonEmpty)
