Question

The title sounds a bit crazy but having the * function for java.lang.String in Scala ("a" * 3 = "aaa"), why don’t we have a / function so that "aaa" / "a" = 3 ?

Answer 1

I like the thinking. I’ll answer with a question: why isn’t there – function when we have a + function?

implicit def strDivider(s:String) = new {
  def /(q:String): Int = s.grouped(q.length).takeWhile(_ == q).size
}

scala> "aaa" / "a"
res0: Int = 3

scala> "abc" / "x"
res1: Int = 0

scala> "aaa" / "aa"
res2: Int = 1
