scala.util.regexp

WordExp

class WordExp extends Base

The class WordExp provides regular word expressions. Users have to instantiate type member _regexpT <: RegExp (from class Base) and a type member _labelT <: Label. Here is a short example: 

 import scala.util.regexp._
 import scala.util.automata._
 object MyLang extends WordExp {
   type _regexpT = RegExp
   type _labelT = MyChar
   case class MyChar(c:Char) extends Label
 }
 import MyLang._
 // (a* | b)*
 val rex = Star(Alt(Star(Letter(MyChar('a'))),Letter(MyChar('b'))))
 object MyBerriSethi extends WordBerrySethi {
   override val lang = MyLang
 }
 val nfa = MyBerriSethi.automatonFrom(Sequ(rex), 1)
