Text Tokenization in Scala

Scala String methods like split and replaceAll are available.

Regex Splitting

val words = text.split("\\s+").filter(_.nonEmpty)

Position Tracking

Find positions using indexOf.

def tokenizeWithPos(text: String): List[(String, Int, Int)] = {
  val words = text.split("\\s+").filter(_.nonEmpty)
  var curr = 0
  words.map { w =>
    val start = text.indexOf(w, curr)
    val end = start + w.length
    curr = end
    (w, start, end)
  }.toList
}

Character Sets

Scala's Set[Char] and exists for char-level operations. Using dropWhile and reverse.dropWhile for trimming custom character sets.
