Scheme/Racket, original miniKanren implementation pays very little attention to what has a significant importance in (specifi- cally) ML or Haskell. In particular

I started studying miniKanren with the book "The Reasoned Schemer - second edition" and the DrRacket scheme environment.

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. 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 .

An embedding of logic programming in Scheme. The miniKanren language in this package is the language presented in Byrd and Friedman’s "From variadic functions to variadic relations" [1]; it is a descendant of the language presented in Friedman, Byrd, and Kiselyov’s The Reasoned Schemer [2]. The code itself was written by (in alphabetical order) Will Byrd, Dan Friedman, Oleg Kiselyov, and Chung-Chieh Shan.

Following the “The Reasoned Schemer” book (second edition), we will learn about relational programming by implementing a version of miniKanren ourselves. Basic knowledge of a lisp-like language (Racket, BSL, Lisp, Scheme, Clojure,…) is presumed. miniKanren-with-symbolic-constraints.

Pastebin is a website where you can store text online for a set period of time. 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 Due to the simplicity of miniKanren, miniKanren can not handle structures con-taining inﬁnite recursion. For example, miniKanren can not handle Scheme code like #0 = ( #0# 3 ).

Racket-miniKanren. Canonical miniKanren implementation in Racket. Asumu Takikawa and Sam Tobin-Hochstadt cleaned up William E. Byrd's Super Chobo Racket code, which in turn was based on the Scheme implementation of miniKanren in the paper: Racket miniKanren-with-symbolic-constraints miniKanren with extensions for symbolic constraint solving.

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.

miniKanren-with-symbolic-constraints. The version of miniKanren I normally use. Includes ==, =/=, symbolo, numbero, generalized absento constraints.. Good for writing Quine-generating interpreters, etc. :) Also includes eigen, which represents universally quanitifed variables.Beware: this implementation does not support use of eigen with constraints other than ==.

Another person has posted about trouble using the Reasoned Schemer 2nd ed code in Racket, but I thought I would add some specifics: My trouble starts in Chapter 1, Frame 50, where conj2 is used. conj2 is not defined in the installed files, so I typed in the definition of conj2 and everything that it depends on, using the definitions provided in Chapter 10. The miniKanren and Relational Programming Workshop is a new workshop for the miniKanren family of relational (pure constraint logic programming) languages: miniKanren, microKanren, core.logic, OCanren, Guanxi, etc.
