typetype Parser = Parsec ByteString ()

typetype GenParser t st = Parsec ByteString st

valueparseFromFile :: Parser a -> FilePath -> IO (Either ParseError a)

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)
             }
