ruby_prolog

An object-oriented pure Ruby implementation of a Prolog-like DSL for easy AI and logical programming. It should work under all popular Ruby interpreters. Please report compatibility problems.

The core engine is largely based on tiny_prolog, though numerous additional enhancements have been made such as object-oriented refactorings and integration of ideas from the interwebs. Unfortunately I cannot read Japanese and cannot give proper attribution to the original tiny_prolog author. (If you can, let me know and I'll update this document!)

Usage

Two runnable examples are included in the 'bin' directory. The first..

ruby-prolog-hanoi

..is a ruby-prolog solution to the well-known "Towers of Hanoi" problem in computer science. The second..

ruby-prolog-acls

..shows the ruby-prolog DSL can be trivially used to implement an access control system. If you have some other useful or clever examples, please contribute them!

Features

Pure Ruby.
Tested with Ruby 2.0.0!
Object-oriented.
Multiple Prolog environments can be created and manipulated simultaneously.
Concurrent access to different core instances should be safe.
Concurrent access to a single core instance might probably explode in odd ways.

Installation

gem install ruby_prolog

See ruby_prolog_spec.rb for usage examples.
