Non-Prolog logic programming

Question

Are there any good non-Prolog or Prolog-based logic programming languages ?

Who has or any good experience with it?

Answer 1

I highly recommend The Reasoned Schemer, by Dan Friedman, Oleg Kiselyov, and Will Byrd. It introduces miniKanren, a small (three core operators) logic programming language built atop Scheme. It's a joy to use, particularly with the matche macro that allows unifying pattern matches.

Answer 2

Answer Set Programming is an extremely powerful logic programming paradigm. I've had a lot of success with the clasp/clingo answer set solver.

Answer 3

I was introduced to DLV and models through answer set programming, which is basically logic programming.

Answer 4

Take a look at theorem proof assistants, like Coq, HOL and Isabelle.

Some type systems (e.g., in Agda2) can be regarded as logic programming too.

Answer 5

You might check out CLIPS. It's structured like Lisp (lots of parens) but it's designed for building expert systems; I haven't seen a problem that Prolog solves that CLIPS couldn't. Like Prolog, its based on building facts and then running queries against them.

Answer 6

There's also pretty fast miniKanren implementation written in Clojure, called core.logic.

There are also a few tutorials on using it:

Answer 7

Mercury and Oz spring to mind. There's also Datalog which is a restricted (non-Turing complete) version of Prolog.
