Hi, I've now got a working OpenGL test-bed and I have also written myself a "GLI" as I call it, openGl command Line Interface... a forkIO thread that listens on port 3000 and once my program is up, I telnet in and issue commands to it so I can fiddle with OpenGL whilst it is running. I can change the camera position and angle and issue a few simple commands to affect the rendered environment so I can better understand how OpenGL works. If it works well and the code isn't to amateurish I will github it I guess! However, it seems to me that I am re-inventing the wheel to some degree: I am opening a socket, getting input, parsing it and executing commands.... what I would really like to be able to do is to *use* the already pretty slick ghci interface instead... ...so, is there a way to create an instance of it and attach it to the socket? f I run my app from within ghci it still works but the event loop steals any further input. So, is it possible. I *did* manage this with SLIME and Emacs some years ago albeit the slime funtionality was a little broken but I could actually recompile code and have it affect the still running application. I've also been using Parsec latelt and the "wai-handler-devel" also entered my mind as an option but I only want a simple CLI after all! :) Thanks for your upcoming suggestions..... Sean
