A very naive but cool arguments parser.

arguments.scala

class Arguments(val rawArgs:Array[String], val flagNames:Seq[String] = Seq()) {

  import Arguments._

  val flags:Seq[Argument]  = 
    rawArgs.intersect(flagNames).toList.map{ s => Flag(s) }

  val values:Seq[Argument] = 
    rawArgs.diff(flags).grouped(2).toList.collect{ case Array(n,v) => Value(n,v)}

  val all = values ++ flags

}

object Arguments {

  sealed trait Argument {
    val name:String
  }
  case class Flag(name:String) extends Argument
  case class Value(name:String, value:String) extends Argument

}
