Minikanren is a relation and logic programming language similar in many respects to prolog. It’s designed to be lightweight and embeddable in other host languages. There is a paper about a minimal implementation call MicroKanren that has spawned many derivatives. It’s impressively short.

Minikanren examples

The appendohexample is simple and has a linear search space. Even so, we hope that this example convinces you that a miniKanren stepper can be a useful debugging tool. In particular, being able to choose which disjuncts to explore is even more helpful for complex miniKanren programs with many disjuncts. Only some of the disjuncts miniKanren is a pure logic language implemented as a purely functional, shallow embedding in a host language, e.g. Racket [10].

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. A video I watched recently on logic programming, A Vision for Relational Programming in miniKanren, by William Byrd gives some interesting examples of relational programming using miniKanren. miniKanren is an embedded constraint logic programming language designed for writing programs as relations , rather than as functions or procedures.

kanren enables the expression of relations and the search for values which satisfy them.

And we use some special constraints. Although, you can use minikanren in such an application, you are missing out on a lot of its power if you do that. An example where such systems shine is program generation, theorem proving, knowledge databases, program verification and other applications where the search space is huge but the rules are relatively simple. Request PDF | miniKanren, live and untagged: quine generation via relational interpreters (programming pearl) | We present relational interpreters for several subsets of Scheme, written in the MiniKanren: 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 Canonical miniKanren implementation in Racket .

A major goal of the workshop is to bring together researchers A miniKanren term is either the empty list, a Boolean constant, a number, a symbol, a logic variable, or a pair of terms. Logic variables start out fresh—that is, they initially have no value—and may later obtain a value through calls to ==. For example, assuming x is a fresh logic variable, (== 5 x) succeeds, and associates x with I have been playing around with miniKanren, trying to understand it by converting very basic Prolog tutorials into it. I use Python habitually so I started with the LogPy library, which has since been forked and improved upon as a lib actually called miniKanren. From the example given in the lib's README we can see: William Byrd explains the ideas behind logic programming languages (like Prolog) and relational programming. Also: miniKanren and core.logic, program synthesis, and much more.

In order to start running miniKanren examples in DrRacket put the following implementation file into a directory: implementation.rkt; Create a file myFile.rkt in the same directory and start with the following incantation: # A video I watched recently on logic programming, A Vision for Relational Programming in miniKanren, by William Byrd gives some interesting examples of relational programming using miniKanren. miniKanren is an embedded constraint logic programming language designed for writing programs as relations , rather than as functions or procedures. Call for Papers. 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. The workshop solicits papers and talks on the design, implementation, and application of miniKanren-like languages.

This project explores multi-stage logic programming in miniKanren. While partial evaluation has a rich history in both functional and logic programming, multi-stage programming has so far only been explored in a functional/imperative setting, with many success stories in high-performance computing.
