Hi all, I was thinking about making some GUIs in Qt/KDE for some haskell applications (compiled with ghc). My first idea was to simply run haskell applications with some args using the GUI and get the results from some file or something like that. Anyway someone told me that a better idea would be to use pipes to enable the GUI to comunicate with the application. I checked the ghc libs and there was a pipe function, but I would need named pipes here (right?) since the two processes are not related. I didn't found any function for that in the ghc libs... is there one? I was also told that another (better way) to do this would be to use sockets. I've worked a little bit with posix stuff (fork, pipes, etc) but I never worked with sockets. I was thinking about using named pipes if that's possible, anyway, Id like to know what you think. Is possible. Is sockets a good solution? better? worth the trouble of learning how to use them? Any better ideas? J.A. PS: Good luck to the GUI task force ;)
