This is me toying around with Prolog, with interest in using it to build inference engines.
For anyone else with a history of developing in Perl, .pl files are Prolog, not Perl. :)
You can quickly install SWI-Prolog with Homebrew:
brew install prolog-swi
Then run the hello world example:
swipl hello_world.pl
TODO
On Mac OS X, use sbcl in order to run Lisp scripts.
brew install sbcl
Then run the hello world script via:
sbcl --script hello.lisp
Why am I playing around with Lisp here, you may ask? I have no idea.
On Mac OS X, you can install CLIPS by downloading the source from SourceForge.
If you want a CLIPS GUI app, download the .dmg file named: clips_macos_executable_[version].dmg.
If you want a command-line Terminal interface, download the .tar.gz file
named: clips_core_source_[version].tar.gz.
Extract the tarball, then run make in the core/ subdirectory:
tar zxvf clips_core_source_[version].tar.gz
cd clips_core_source_[version]/core
make
Then copy the generated clips executable to your path, something like:
cp clips /usr/local/bin/
Then you can spawn a CLIPS REPL by running:
clips
And type (exit) in the REPL to get out of it.
The CLIPS sample scripts in the ExpertSystems subdirectory were cloned from https://github.com/jtonyortiz/ExpertSystems.
