Hi everyone,
So I trying to develop what amounts to a new implementation of the Pd GUI. The first step was of course to remove the old GUI, which is actually a lot simpler than I thought. Pd can actually be launched with a -nogui flag, which keeps the gui from opening. Even more excellently, Pd can be launched with the guiport flag, which tells Pd to listen for input from a GUI outputting to the specified socket.
The problem is that I have no idea where to get started on learning how Pd communicates with the GUI. All I know is that messages are sent back and forth over a socket, typically 5400. The source code is fairly impenetrable; what would really be nice is if someone could point me towards what I need to look at to figure out how the Pd-GUI message system works. If there is a guide, or if someone could tell me where to focus my attack on the source code, that would be great.
Thanks very much,
Sam
