parseFromFile :: Parser a -> String -> IO (Either ParseError a)Source

parseFromFile p filePath runs a lazy bytestring parser p on the input read from filePath using ByteString.Lazy.Char8.readFile. Returns either a ParseError (Left) or a value of type a (Right). 

  main    = do{ result <- parseFromFile numbers "digits.txt"
              ; case result of
                  Left err  -> print err
                  Right xs  -> print (sum xs)
              }
