On the flip side, Parsec is really nice. I wonder how easy it would be to make it parse [Word8] instead of String?
Isn't Parsec parameterized over the token type?
Or even a FastPackedString? (And how easy it would be to get that instead of a String from hGetContents)?
From the FPS haddock:
hGetContents :: Handle -> IO FastString
Read entire handle contents into a FastString.
This may or may not do what you want...it's probably not a lazy read.
If it can be implemented via 'mmap' then it is effectivly a lazy read. and _very_ efficient to boot.
True, I forgot mmap. Taking a look at the implementation reveals that it indeed uses mmap (if available on the platform). Ben
