type GenParser t st = Parsec ByteString st Source #
parseFromFile :: Parser a -> FilePath -> 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)
}
