Finder Description Generators first_finder Search for the first match of the string in an input first_finder() last_finder Search for the last match of the string in an input last_finder() nth_finder Search for the nth (zero-indexed) match of the string in an input nth_finder() head_finder Retrieve the head of an input head_finder() tail_finder Retrieve the tail of an input tail_finder() token_finder Search for a matching token in an input token_finder() range_finder Do no search, always returns the given range range_finder() regex_finder Search for a substring matching the given regex regex_finder() Formatter Description Generators const_formatter Constant formatter. Always return the specified string const_formatter() identity_formatter Identity formatter. Return unmodified input input identity_formatter() empty_formatter Null formatter. Always return an empty string empty_formatter() regex_formatter Regex formatter. Format regex match using the specification in the format string regex_formatter()
