Description
Convinience definitions for working with ByteString
s.
type Parser = Parsec ByteString () Source
type GenParser t st = Parsec ByteString st Source
parseFromFile :: Parser a -> FilePath -> IO (Either ParseError a) Source
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)
}
