Clojure Gazette

Declarative Programming

Declarative programming means telling the computer what instead of how. SQL is declarative: you say what data you want. It is up to the database to figure out how to give it to you.

Declarative programming is having a slight resurgence at the moment. Clojure is feeling it, and I thought I'd tap into it that for this issue.

Have fun!

logic, again

core.logic

core.logic is a Prolog-style logic language embedded in Clojure. It is shaking things up. I've referred to core.logic before, but I repeat it because it is the perfect example of declarative programming in Clojure.

Out of the Tar Pit

A great paper that analyzes common sources of complexity in software and traditional approaches to managing that complexity. It ends with a wide-eyed proposal for dealing with complexity by focusing on declarative programming.

The Future is Parallel, and the Future of Parallel is Declarative

A somewhat different take on declarative programming: functional programming is declarative. I mostly disagree with this. I think in general functional degrades into a strict form of procedural programming. But it is good to see another perspective.
