Prolog+CG Portable

Made as the portable edition of Prolog+CG, this is a small-sized software application written in Java, which provides you with a user-friendly IDE for Prolog, the programming language used for AI and computational linguistics.

As long as you have Java installed, you can simply drop Prolog+CG's files in a custom location on the disk or on a removable storage unit and directly launch it on any computer. An important aspect worth noting is that, unlike most installers, it doesn't add new entries to the Windows registry or Start menu, thus leaving no traces behind after removal.

The interface consists of a command-line dialog and a graphical window which run together side by side. In the main frame you can type or paste Prolog code, save it as a Prolog+CG file (.prlg, .plgcg), as well as configure settings before deploying the applet when it comes to the title, width and height, number of boxes and buttons, along with box and bbutton labels. Alternatively, you can import an applet from a pre-existing XML file.

It's possible to jump to a specific line of code, change the font size and make text bold, compile the project, stop the execution, and ask the tool to answer questions written in the Prolog code. The application also has a built-in list with descriptions about primitive goals (e.g. arithmetic, relational, randomness, logical).

We haven't come across any stability issues in our tests, thanks to the fact that the utility didn't hang, crash or display error messages. It had minimal impact on the machine's performance, using low CPU and memory.

On the other hand, its set of features and configuration settings is not rich. Nevertheless, Prolog+CG supplies you with a clear-cut environment for implementing Prolog code.
