Folks,
Are there any endian conversion routines for Haskell? I'm looking to build binary packets on top of NewBinary.Binary but my data is coming in little-endian whereas I'll need to send it out big endian.
From your question I assume you want functions like htonl / ntohl. I think the cleanest approach is to always have yours Ints, etc in host order, and place
the endianness stuff in serialization / deserialization code, ie. on the Number <-> Byte sequence boundary. 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. Best regards Tomasz
