Sorry took so long to get back... Thank you for the response. Been really
busy lately :-)

Anyone got some "tricks" for this? Dave You could just define data type and Binary instance for 9P messages.
Something
like this: P9Message = Tversion { tag :: Word16, msize :: Word32, version :: String }
| ... instance Binary P9Message where
put (Tverstion t m v) = putWord16le t >> putWord32le m >> put v
-- and so on... get = do
length <- getWord32le
id <- getWord16le
case is of
p9TMessage -> do ... There are a lot of boilerplate code thought... Thank you, this still looks like a useful way to proceed, combined with the
BinaryLE approach perhaps, to avoid a lot of boilerplate. BTW could you say what do you want to do with 9P? I tried to play with it
using libixp library but without any success. It was mainly to understand
how
does it works and how can it be used. From a services point of view, 9P gives you a way to host them, and even
devices, on a network share that can be "mounted" into the filesystem's
namespace. The net result is you've plugged into the standard unix
utilities that do open, read, write etc, and can do a lot of interesting things with mere shell scripts.
Operating systems that can be clients of a 9P service include Linux,
Inferno, Plan 9, and anything else that runs FUSE 9P (several BSDs). From a client perspective, having a 9P implementation gives you a more
fine-grained programatic interface to accessing other 9P services. There are also a lot of 9P implementations in many languages that you can
interoperate with:
