| Hello,
sorry for the late.
There is no automatic way to do this. The trace is only available under the debugger and there is no simple way to write in on a socket. The best way is to write you own meta-interpreter which could then output all needed information during the execution of a goal. You can obtain more information on meta-programmaming in these books: "Programming in Prolog" by Clocksin & Mellish, "The Craft of Prolog" by R. O Keefe.

Le 2 août 2011 à 17:39, Paolo Parise a écrit : I'm Parise Paolo and I've developed a game using Prolog. For demonstration
issues and through your Prolog interpreter gprolog, I want to
execute, using an external program developed in Java (called controller) the following loop:
1: (gprolog) execute a portion of the game
2: (gprolog) stop the execution and send to the controller the trace, finally wait for the controller acknowledge
3: (controller) receive and print the trace (call, exit etc..), ack to che gprolog program
4: (gprolog) ack received, execute the next portion of the game
5: (gprolog) stop the execution and send to the controller the trace, finally wait for the controller acknowledge
6: (controller) receive and print the trace (call, exit etc..), ack to che gprolog program
7. ... and so on
Start and stop are messages through a TCP connection but I don't know how
the controller can receive the prolog trace. Does gprolog provide a
file logging (the controller can read the file)? Have you got advices?
Thanks!!
Paolo Parise
