Hello, Nils. Can you describe if there any difference with latest conduit API (yield, await) that can be used to write functions in a very similar style, but without using exeternal packages:
runTCPServer settings app = appSource ap $$ go =$= CL.mapM_ encode =$ appSink app where go = forever $ do bp <- decode <$> await {- decode is inlined here assuming it can return different types -} {- logic here-} yield $ result mapM (yeild) [result1,result2...]
more over you don't need to write appSource $$ ... appSink on the top. Here is an example of a client that authorizes and then reads commands from TBMChan and requests server using json format.
runTCPClient settings ad go where go = do source $$ await is <- authorize when is loop' authorize = do yield u >> yield (S8.pack "\n") $$ sink -- send authorization token mx <- source $$ sinkParser json -- get responce ... loop' = do minfo <- atomically $ readTBMChan ch case minfo of Nothing -> return () Just (message, respBox) -> do yield message $$ C.concatMap (SL.toChunks . encode) =$ sink resp <- source $$ sinkParser json atomically $ putTMVar respBox resp loop' source = ppSource ad sink = appSink ad

Hello everyone,
I just uploaded my "conduit-network-stream" package to hackage. It's a base layer for network protocols based on the "Conduit" package by Michael Snoyman which makes it possible to send multiple messages over a continuous network connection in a convenient way.
I wrote more about it at:
https://github.com/mcmaniac/**conduit-network-stream/blob/** master/README.mdhttps://github.com/mcmaniac/conduit-network-stream/blob/master/README.md
It is available on hackage and github:
http://hackage.haskell.org/**package/conduit-network-streamhttp://hackage.haskell.org/package/conduit-network-stream https://github.com/mcmaniac/**conduit-network-streamhttps://github.com/mcmaniac/conduit-network-stream
Until the documentation on hackage is generated, I also host the haddock documentation at:
http://hs.nils.cc/conduit-**network-stream/index.htmlhttp://hs.nils.cc/conduit-network-stream/index.html
For any questions/problems/requests, please ask!
- Nils
