OpenRegex-scala provides scala bindings against OpenRegex. The Scala bindings use Scala collections as well as providing a more familiar API for Scala users.

OpenRegex-scala also includes a PatternParser implementation that uses reflection to run over any class out of the box. Any public field or 0-argument method may be used to match against a string. There is an exact string matcher (single quotes) and a regular expression matcher (forward slashes). Multiple aspects of a class can be matched against and combined with a logical expression.

    case class Point(x: Int, y: Int)
    val parser = PatternParsers.reflectionWithLogic[Point]
    val regex = parser("<x='1' | x='2'> <x='3' & y='3'>")
    regex.matches(Seq(Point(1, 1), Point(3, 3)))

Using regular expressions, the pattern could have been expressed equivalently.

    val regex = parser("<x=/[12]/> <x='3' & y='3'>")
