Ruleby: The Rules Engine for Ruby
summary
Claims a pure Ruby Rete engine that compiles rules into a node network, shares nodes to avoid redundant checks, and stores partial matches to speed execution; rules live in a rulebook class and facts are ordinary objects that the engine handles via assert/retract facts. Demo runs (hello→goodbye chain) and the project is a gem on GitHub. Trade-offs: higher memory use and overhead for problems that must evaluate every rule against every fact.
