for just making IO and a little bit-conversion, i would use c++ or even c. for such a problem you have to be near the machine, not necessarily near mathematical abstraction. there exist assembler-commands to flip endians of register-values, so i would just search in /usr/include/*/* for a platform independent c-function, and either pipe a proxy through such a little prog, or patch an existing proxy, like "tinyproxy". of course, if you want to make more than just a proxy, or if you want to play with different languages, be welcome to use haskell. but remind, it is not easy to use high-developed-mars-rover-technology to replace a shovel for playing with sand at the beach. - marc Joel Reymont wrote:
Well, I'm looking for suggestions on how to implement this. I'll basically get a chunk of data from the socket that will have things little-endian and will need to send out a chunk that will have the numbers big-endian.
This is a proxy server that does binary protocol conversion. It's a breeze to implement in Erlang but I'm partial to Haskell and trying to apply it to all sorts of problems. Please, let me know if this is not the type of problem to apply Haskell to ;-).
Thanks, Joel

Having htonl/ntohl as pure functions in Haskell would be a bit ugly, because they would be defined differently on different platforms, and putting them in the IO monad would make them barely usable.
