type Parser = Parsec ByteString () #
type GenParser t st = Parsec ByteString st #
parseFromFile :: Parser a -> String -> IO (Either ParseError a) #
parseFromFile p filePath
runs a strict bytestring parser p
on the
input read from filePath
using 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) }
