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

Question

This common pattern feels a bit verbose:

if (condition) 
  Some(result)
else None

I was thinking of using a function to simplify:

Answer 1

Here is another approach that is quite straightforward:

Option(condition).collect{ case true => result }

A simple example:

scala> val enable = true
enable: Boolean = true

scala> Option(enable).collect{case true => "Yeah"}
res0: Option[String] = Some(Yeah)

scala> Option(!enable).collect{case true => "Yeah"}
res1: Option[String] = None

Here some advanced non-Boolean examples that put the condition into the pattern match:

val param = "beta"
Option(param).collect{case "alpha" => "first"} // gives None

Option(param).collect{case "alpha" => "first"
                      case "beta"  => "second"
                      case "gamma" => "third"} // gives Some(second)

val number = 999
Option(number).collect{case 0 => "zero"
                       case x if x > 10 => "too high"} // gives Some(too high)
