clara-rules

Interestingly https://github.com/cerner/clara-rules redirects to https://github.com/oracle-samples/clara-rules so I'd guess Cerner was acquired by Oracle, although the repo is Apache 2 and doesn't seem to have any weird stuff in their contributing.md For me, the "It's just Clojure" part is a drawback, not only for me personally but when I think about the kind of audiences that I have traditionally wanted to author rules, between a real, lisp-y, dynamically-typed, programming language and asking folks to write in the Drools DSLs, I'll take my chances with the DSLs

I've met a few young programmers who heard somewhere that object-oriented programming was bad and they want to get the enlightenment of functional programming that they've heard about. Frequently they travel from job to job like itinerant martial artists always looking for somewhere where they practice the true technique but they always seem disappointed as it is just as easy if not easier to screw up handling errors with monads than it is with exceptions and they find analogies like "a monad is like a burrito" just get them more confused. As for something profound I'd point you to https://github.com/cerner/clara-rules which many people will struggle with because like many other production rules engines in LISP (and many other examples of simple compilers), there is hardly any code! Contrast that to the orders of magnitude larger rules

In Clojure-land, there are a few similar projects. I enjoy working with Clara: http://www.clara-rules.org, https://github.com/cerner/clara-rules

I'm not aware of a JS adapter for clara rules but per the wiki it does offer ClojureScript support "with a couple constraints"[1] [1] https://github.com/rbrush/clara-rules/wiki/ClojureScript

Has anybody in the client side community ever made the connection to rules engines? This flow of logic is awfully close to how a rule engine works. I wonder if people will at some point arrive at it. There isn't a whole lot of rules engine in JS. Just nools [1] which is huge. I'd love to see a very simple forward chaining rule engine + Immutable + React and see how that would work out. My guess is that they aren't popular at all because they have the notion of being enterprisey (Drools/Jboss). I'm a big fan of them. They /can/ make life & code very nice and elegant. Maybe somebody writes an JS adapter to clara rules [2]. [1] https://github.com/C2FO/nools [2] https://github.com/rbrush/clara-rules
