Text.Parsec.ByteString.Lazy

Description

Convinience definitions for working with lazy 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 lazy 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)
             }
