A scala implementation of this https://github.com/schatteleyn/Convertor

convertor.scala

import java.util.regex.Pattern

def convert(in: String, delimiter: String) = in.split(Pattern.quote(delimiter)).toList.map(str => str.head.toUpper+str.tail).mkString(delimiter)
def convert(in: String):String = convert(in, "\n")

// Test with delimiter & without
println(convert("bli\nbla\nblu"))
println(convert("bli$bla$blu", "$"))

Conding functions in one line was just a challenge for fun ;)
