Description
Convinience definitions for working with ByteStrings.
Synopsis
- type Parser = Parsec ByteString ()
- type GenParser t st = Parsec ByteString st
- parseFromFile :: Parser a -> String -> IO (Either ParseError a)
Documentation
type Parser = Parsec ByteString () Source #
type GenParser t st = Parsec ByteString st Source #
parseFromFile :: Parser a -> String -> 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)
}
