A logic programming library for Clojure & ClojureScript. core.logic offers Prolog-like relational programming, constraint logic programming, and nominal logic programming for Clojure. At its heart is an original implementation of miniKanren as described in William Byrd's dissertation Relational Programming in miniKanren: Techniques, Applications, and Implementations as well as the extensions described in cKanren and alphaKanren. It is designed to be easily extended to forms of logic programming beyond the ones provided.
If you wish to work through The Reasoned Schemer with core.logic make sure to look over this first.
