Re: [Haskell-beginners] command-line interaction with running process

Thanks for this answer - that's a good point. At this point it's mostly for (interactive) game/level design and testing though :) On 4 March 2015 at 10:45, Sumit Sahrawat, Maths & Computing, IIT (BHU) wrote:

If you decice upon the server-client architecture, you should take a look at zeromq. It is used extensively in IHaskell, so you can peek at the code there for a working example.

Also, I believe a client-server architecture will be better as I personally enjoy games a lot more when they are multi-player. It makes the conversion from single-player to multi-player a non-destructive (or atleast less destructive) process.

Hi,

I'm trying to do the following: implementing a command-line interface to directly interact with the state or the parameters of a looping/running process (a game, to be specific).

My first thought is to fork a thread, passing in a TChan/TVar or similar to enable communication, and to have the command-line interface on the thread (getLine or haskelline ...). Another option would be to have a bona fide server-client interface (with sockets or others), to fork a thread again to run the server and to connect using the client library - which would allow me to use ghci and have transparent serialization under the hood.

Are there known use cases? Am I missing something, for instance is it possible to interact with a running process directly using ghci? Any tips?

Thank you,
