Besides miniKanren there were also a couple of other good talks on day 1, I particularly liked Wojciech Ogrodowczyk‘s Beyond Ruby talk where he used the Piraha people as example to demonstrate why it’s so important to be polyglot. It’s one of the angles I used in my Tour of Language Landscape talk at NDC Oslo too.. p.s. you can find all the code for William’s workshop and talk on

We solve each challenge by using an interpreter for a subset of Racket, or for a slight variant of Racket. These interpreters are written as relations in the constraint logic programming language miniKanren. Each interpreter relates two arguments: an expression expr to be evaluated, and the value val to which expr evaluates.

It separates the core implementation from the surface syntax, and is just over 50 lines of code in length. Our miniKanren implementation will use constraint solving and search to fill in the logic variables with expressions and values consistent with the semantics of Racket. By placing logic variables representing unknowns in different positions within the expr and val arguments we can express a wide range of interesting queries, which provides the flexibility needed to solve the variety of Canonical miniKanren implementation in Racket .

There is also run , which serves as an interface between Scheme and miniKanren miniKanren is an embedded Domain Specific Language for logic programming. miniKanren is a pure logic language implemented as a purely functional, shallow embedding in a host language, e.g. Racket [10]. microKanren [13] is an approach to clarifying miniKanren’s complexities.

The University of Utah (3) Indiana University Bloomington (2) Minikanren provides the following new core forms, which comprise the core of the miniKanren language. These forms are all described in much greater detail in Byrd and Friedman’s "From variadic functions to variadic relations" [1], which those interested in learning how to use this library should consult. Racket-miniKanren.

Racket miniKanren-with-symbolic-constraints miniKanren with extensions for symbolic constraint solving. Includes compatibility files for Racket and various Scheme implementations. cKanren miniKanren extended with Constraint Logic Programming (CLP); an improved version of the system described in the 2011 Scheme Workshop paper. Racket-miniKanren

miniKanren is a family of programming languages for relational programming. As relations are bidirectional, if miniKanren is given an expression and a desired output, miniKanren can run the expression "backward", finding all possible inputs to the expression that produce the desired output. Usually, in miniKanren programs, not putting a recursive goal last is asking for trouble. Since one of them has to come not-last, it's difficult to avoid divergence. Having said that, perhaps someone else will chime in with a better answer.

I was reading TRS and wanted to run the code, but I didn't have (and didn't feel like getting) Clojure or Racket.

As relations are bidirectional, if miniKanren is given an expression and a desired output, miniKanren can run the expression "backward", finding all possible inputs to the expression that produce the desired output. We present seven programming challenges in Racket, and an elegant, unified approach to solving them using constraint logic programming in miniKanren. miniKanren-with-symbolic-constraints. The version of miniKanren I normally use. Includes ==, =/=, symbolo, numbero, generalized absento constraints.. Good for writing Quine-generating interpreters, etc.
