Re: [Haskell-cafe] Join Manatee Team!
Hi, From your error, you need re-install package `derive` and `regex-tdfa`, then re-install manatee again. BTW, follow the step i wrote at http://hackage.haskell.org/package/manatee Please let me know if you have any problem with Manatee.

Hi all, I'm Andy, the author of Manatee ( http://haskell.org/haskellwiki/Manatee ). You can watch video http://www.youtube.com/watch?v=weS6zys3U8k (or http://www.youtube.com/watch?v=A3DgKDVkyeM ) to understand "What is it?" . :) Manatee is Haskell integrated environment written in Haskell. The goal of the Manatee project is provide a fast, safe and flexible integrated environment for haskell hacking.

I have came back to looking at the binary package, the only thing is I think I have to build my own primatives with it as it is big-endian, where ActionScript Byte Code format is little-endian. It does provide some little-endian functions but they are not brought to the surface. It also seems to roll its own serializations. I am maybe looking at doing my own specialized set of types and binary backend as there are drawback with each of the existing solutions. - Data.Storable.Endian - peeks and pokes rather than put/get - Data.Word24 - peeks and pokes rather than put/get - Data.Binary - big-endian ABC format may best be supported by a specific set of serialization types. On a different note thinking outside this problem, I would like IO_LE and IO_BE types if that could be make to work.

The Int# is built-in to GHC; it's an unboxed Int type (C long int, see
http://www.haskell.org/ghc/docs/7.0-latest/html/users_guide/primitives.html#glasgow-unboxed
). I24# is not built-in; it's just a normal constructor. Although it has a
hash suffix, that's just a convention (as documented under the MagicHash
pages); it behaves exactly like any other constructor.
This means that an Int24 works just like an Int, Int16, etc. It can be lazy,
but will also be unboxed by GHC when appropriate. Arithmetic on the unboxed
type will result in machine ops. This isn't strictly necessary; Int24 could
be nearly equivalently defined as
data Int24 = Int24 {-# UNPACK #-} !Int32
but using unboxed types is perhaps more efficient. The UNPACK pragma wasn't
available when I wrote Int24, which is why I did it this way. I may revisit
this decision in the future; unboxed types are tied closely to GHC, and the
UNPACK/strict combination would be more portable and easier to maintain.

Int# is the raw machine int (4 or 8 bytes) and I24# is the constructor.
