I'd also look at

https://github.com/oakes/odoyle-rules/

I think the userbase is slowly shrinking, but I'd personally use Clojure even if all Clojure developers disappeared tomorrow. It's not built on shifting sand as the JVM is stable. If you need really niche/cutting edge stuff you're probably going to need to dip into Java or JS interop anyway

Thanks for the link! I’m not the parent poster, but I was thinking of using Clara Rules for prototyping a game idea and to get some experience with rule engines. I don’t think that truth maintenance (which is handled by Clara and not O’Doyle) is important for my use case, and O’Doyle looks simpler to pick up.
