I don't think there's enough information in the snippet you've given to determine what the problem is. And in general, it's a good idea to include the actual error message from the compiler. On Mon, Nov 12, 2012 at 5:02 AM, Alexander V Vershilov < alexander.vershilov@gmail.com> wrote:
Hello.
I have problems with writing next code (using network-conduit)
slightly simplified version:
app ad = appSource ad $$ sink where cMap = M.fromList [ ("upload", cmdUpload), ("download", cmdDownload) ] sink = takeLine >>= \c -> case c of Just run -> run ; Nothing -> return () cmdUpload = {- ... -} CB.sinkFile path cmdDownload = do {- code here -} CB.sourceFile path $$ appSink ad -- this will not work because of -- type error
And I'm catching "cannot construct the infinite type".
I've found an example in [1], but it's not exactly solves my problem, as all the logic is inside conduit, and it will break upload function.
