Hi, does anyone have code (or directions) for setting up an interface between Sicstus/Quintus Prolog and Suntools? I want to be able to output and input to a Prolog program via various types of window. However, due to the nature of Suntools a simple foreign language interface won't suffice. I presume that what is required is to set up an interprocess communication between Prolog and a C program to perform the actual window handling. However, I have never tried this, and was wondering if anyone has experience (or even code) for setting up such an interprocess communication. Thanks in advance, Afzal Ballim University of Geneva (afzal@divsun.unige.ch) :

Quintus Prolog has a sample window library for Suntools. It uses foregin libarary interface for C. It also works on sicstus prolog. Generally it is not difficult to write simple interface to Window or Socket in SICStus/Quintus. I wrote one general socket interface and a window interface for GMW (Tateishi-Omron Japan's window system, nobody knows :-). One advantage of using prolog is this: you can use repeat fail for dragging. ?- get_newevent(X), drag_something(X), check_event(X). drag_something(X) :- write_something(X). drag_something(X) :- get_newevent(X1), erase_something(X), drag_something(X1). This is very slow in interpreter, but reasonably fast in compiler. But these make Prolog really BIG, and using low window interface is real pain. Real problem is high level interface design for various window system. -------- Shinji Kono $@2OLn??<#(J Sony Computer Science Laboratory, Inc.: kono@csl.sony.co.jp
