Hi, I am looking for a way to extend GHCI such that I can do something like this
$ ghci GHCi, version 6.12.3: http://www.haskell.org/ghc/ :? for help Loading package ghc-prim ... linking ... done. Loading package integer-gmp ... linking ... done. Loading package base ... linking ... done. Loading package ffi-1.0 ... linking ... done. Prelude> startMyFunction Prelude>
startMyFunction will do a forkIO and listen on a network port for interaction with a remote process and will drop back to GHCI prompt where I can invoke haskell functions that'll control the way the interaction with the remote process occurs. Can this be done? I am not sure that I understand you correctly, but ghci simulates the IO monad, so what about:
Prelude> :l MyModule.hs *MyModule> conn <- waitForAndAcceptConnection *MyModule> someData <- getSomeData conn *MyModule> sendSomeAnswer conn $ processSomeData someData ... -- Steffen
