Read in data strictly, and there are two obvious ways to do that:
-- Via strings:
readFileStrict f = do
s <- readFile f
length s `seq` return s
-- Via ByteStrings
readFileStrict = Data.ByteString.readFile
readFileStrictString = liftM Data.ByteString.unpack
Data.ByteString.readFile
If you're reading more than say, 100k of data, I'd use strict
ByteStrings without hesitation. More than 10M, and I'd use lazy
bytestrings.
