Hi all, I'm writing a Haskell program to do some address cleansing. The program uses the ByteString library.
Data.ByteString.Char8 documentations shows functions for removing whitespace from start or end of a ByteString. Those functions are said to be more efficient than the dropWhile / reverse mixes. It looks exactly like what I'm searching for, but apparently those functions are not exported by the Data.ByteString.Char8 module. Are those functions only called by rules? Transformation of dropWhile isSpace into dropSpace? I've seen such a rule for dropSpace but did not found an equivalent rule for dropSpaceEnd. Is there a way to call the dropSpace and dropSpaceEnd or do I have to code with dropWhile and hope that some rule will magically transform my dropWhileS into dropSpaceS? Thanks, Olivier.
