What if your Java program was just... data?

Higher-Kinded-J v0.4.1 introduces Effect Handlers — where domain operations are records, workflows are data trees, and interpreters decide what happens.

Same program. Four interpretations:
✦ Production — real API calls
✦ Testing — pure values, no mocks
✦ Audit — every step logged
✦ Dry-run — estimate cost without executing

No code duplication. No mock frameworks. Just data, interpreted differently.

This is Data-Oriented Programming.

Your operations are records. Your effect algebra is a sealed interface. Your interpreter is a switch expression. Add an operation? The compiler forces every interpreter to handle it.

Inspect programs before running them — count external calls, find recovery points, estimate cost.

Analyse programs like data.

Built on records, sealed interfaces & pattern matching. No exotic FP import — just modern Java, composed well.

Still coupling logic and data in your #Java code? #DataOrientedProgramming with records and #PatternMatching lets you model valid states cleanly and move logic out of your types.

#ProjectAmber #CleanCode #DataOrientedProgramming

I've been so quiet lately because I've been busy building my 1st full stack app with Clojure(script). It's been a lot of fun and I've learn a ton, not only about clojure but about functional and data oriented programming too.

Expect updates.

#DomainModeling with @TypeScript 2.0.0 has arrived. It promotes clean separation between data and behavior and utilizes the algebraic properties of a TypeScript type system.
