///  })
///  Splits the string, converts its parts, and combines them into a new string.
///
///  pattern is used to split the string into parts and separating matches.
///
///  Each match is converted to a string by calling onMatch. If onMatch is
///  omitted, the matched string is used.

///  Each non-matched part is converted by a call to onNonMatch. If onNonMatch is
