SWI-Prolog 7.2.3 for Mac is free to download from our application library. The most recent installer that can be downloaded is 19.5 MB in size. The following version: 6.6 is the most frequently downloaded one by the program users. SWI-Prolog offers a comprehensive free Prolog environment. Since its start in 1987, SWI-Prolog development has been driven by the needs of real world applications. SWI-Prolog is widely used in research and education as well as commercial applications. Join over a million users who have downloaded SWI-Prolog. Hi, A real Prolog MacOS app is getting close to testing phase. One of the remaining issues is integration with the finder. Below are some thoughts about that. Comments from Mac users is welcome. Currently, I register Prolog for.pl and.prolog files (still need to figure out how to get an icon there). Double clicking always sends a message to the already running app, while I think.

CSE 341 - Programming Languages

We're using SWI Prolog, version 6.2.6.

When you start Prolog, you should see an introductory greeting and then the Prolog command prompt:

Running Prolog on attu

If you're planning on loading a file, it will simplify things to first navigate to the directory that contains your file, so that Prolog can find it easily.

In any case run Prolog from the command line using

Run Prolog from the “Start” menu. It's here:
All Programs / DEV TOOLS & LANGUAGES / SWI-Prolog

If you want to load a file, you'll either need to specify an absolute file path, or change the current working directory to the appropriate place. Here's how to change the current working directory. If your files are in your home directory on the Z drive in the cse341 subdirectory, type this at the Prolog command prompt:

(The double backslash is needed because a single backslash indicates some special character, e.g. n for newline. And in case you're wondering, X will be unified with the previous working directory.)

Double-clicking on a .pl Prolog source file is going to start perl, so that's not going to work.

Running Prolog on a Personal Machine

SWI Prolog is available for Windows, Mac, and Linux. Here's the download page: http://www.swi-prolog.org/Download.html.

A few additional Macintosh hints: if you use the Finder and double-click on SWI Prolog in Applications, depending on your security settings, you may get an error. If you do, try right-clicking (or control-clicking) on the application instead, and say “run it anyway”. You can also run it from the command line using the swipl executable in /Applications/SWI-Prolog.app/Contents/MacOS, assuming you installed it in the default location. To use the graphical debugger, install xquartz (X11), then open a X11 terminal, and run Prolog from there.

Basic Prolog Commands

A few essential commands:

Swi Prolog Mac Terminal

halt.: exit Prolog (short form: control-d)
consult(filename).: load the file named filename.pl (note the added .pl extension). If you need some more complex name (for example with a path), put it in single quotes, for example consult('/Users/schmertzkopf/squid.pl').
[filename].: shorthand for consult
help(topic) or apropos(topic).: Brings up the relevant section of the manual in a separate window (so requires X for linux/Mac).

Editing Prolog Code

Prepare source files using any convenient editor. The standard file extension for Prolog files is .pl

If you want to use emacs, include this in your .emacs file in your home directory: (Without this, emacs is going to think you're writing in perl.)

There are other versions of emacs Prolog mode if you want to try one - see e.g. Using SWI-Prolog with GNU-Emacs. However, the default mode should be fine for 341.

Debugging

SWI Prolog provides two interfaces to the debugger: a text-based and a graphical interface:

The graphical debugger doesn't seem to be installed with the version of Prolog on the Lab linux machines, unfortunately. It is on the Lab Windows machines, though.
