Ask HN: Where do I find good code to read?
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 engine Drools
https://github.com/kiegroup/drools
which is so crazy-complicated primarily because the Drools language is Java-based so you need all sorts of things that Clara or CLIPS don't need.

SourceBuddy Brings Eval To Java
IMHO you're better off using something like https://www.drools.org/ for this. Non-devs writing code is a pipe-dream. It never works out.

Behavior Driven Testing and Drools
Hopefully you already know that Drools is a business rules management system. You write rules in either "drl" syntax, in spreadsheets, or in glorified flowcharts, and then let your application throw data at it.

Optimizing Decision Making with a Trie Tree-Based Rules Engine: An Experience Report
First, I transformed this Trie Tree implementation into an open-source project, which I called Praecepta (Rules in Latin), so anyone can try it out. Then, I added three modules to it, with a decision table based on a real scenario (blurred input/output values). Each module uses a different framework: Praecepta, Camunda 7, and Kogito (the newest Kie solution for the Cloud).
