GNU Prolog development environment.


XGP is an integrated development environment for GNU Prolog. It extends Prolog with builtins for native Cocoa-based GUI (menus, dialogs) and simple interactive Quartz graphics. Much of the XGP IDE is itself implemented in Prolog.

What's new in XGP

Version 1.1.1:
  • Updated XGP to build for Mac OS X 10.5.x (Leopard).
  • This update required rebuilding GProlog 1.3.0 with gcc 4.0.1 and rebuilding XGP with a new XCode 3.0. This is (still) an Intel-only version of XGP.
  • Added graphic window "tools" for interacting with graphics.
Version 1.1:
  • This is a native update for gprolog version 1.3.0 on Mac Intel. This version does not run on PowerPC.
  • Fixed setup to check for presence of both pl and wbc files and to use the wbc file unless the pl file is newer.
  • New version of XGP Guide, generated using TeX.
Version 1.0:
  • This version of XGP upgrades to use a customized gprolog version 1.2.19.
  • There are several improvements to the XGP environment: preemptive halting, scripts (implemented in Prolog), and improvements for the 'Find in Files...' and 'Evaluate Query...' dialogs.
  • The menu definition utilities for stand-alone applications have been improved.
  • There are some new control-window/dialog features: progress bar control window item, banner dialog with a progress bar, better auto-resizing of control window items, and better handling of color.
  • Finally, there are many bug fixes.
