Apr 22, 2011 A standard example is that of length on lists (in Haskell syntax): length : [a] -> Int length [] = 0 length (x:xs) = 1 + length xs. Execution of length

miniKanren betonar ren (klipp inte tillåten) logisk programmering. Denna Haskell kommer fullt utnyttjande av lathet och kommer närmast programmering i ren 

It's such a brain bender and it seems well suited for some PL things. E.g. say you have some custom interpreter. If you implement that interpreter in Minikanren, you can run it backwards and answer the question "what program, if any, evaluates to this result". Haskell's core language is very small, and most Haskell code desugars to either: lambdas / function application,algebraic data types / case expressions,recursive let bindings,type classes and specialization, or:Foreign function calls Once you understand those concepts you have a foundation for understanding everything else within the language. You cannot write an equivalent Haskell program easily because Haskell has a different execution model.

We then layer over it, in 43 lines, a reconstruction of an existing logic programming language, miniKanren, and attest to our implementation's pedagogical value. Evidence suggests our combination of expressiveness, concision, and elegance is compelling: since microKanren's release, it has spawned over 50 embeddings in over two dozen host languages, including Go, Haskell, Prolog and Smalltalk. 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 And miniKanren has been ported to dozens of host languages, including multiple Haskell implementations. As far as the types making things easier, I'm not sure this is true.

Topics of interest include: Language design, with a focus on possible extensions and modifications of Haskell as well as critical discussions of the status quo; Theory MiniKanrenT. An implementation of miniKanren in Haskell.

miniKanren macht eine Reihe von Kompromissen, um diesen relationalen Stil der Programmierung zu ermöglichen, der sich sehr von den Kompromissen unterscheidet, die Prolog macht. Im Laufe der Zeit hat miniKanren mehr symbolische Einschränkungen hinzugefügt und wurde zu einer symbolisch orientierten Constraint Logic Programmiersprache.

miniKanren is designed to be easily modified and extended; extensions include Constraint Logic Programming, 2012-12-08 · My weapon of choice is Haskell, so here you go, a miniKanren monad transformer in Haskell: miniKanrenT. Monad Transformers FTW! It turns out there is a very nice monad transformer by Dan Doel (based on a paper co-authored by Friedman) that does the backtracking and interleaving for me.

Minikanren haskell

Are there any plans to include a 'standard' miniKanren implementation as a core library in Haskell? (by core I mean a library that could be found, for example, in the Haskell Platform) Bonus question : what's your takes, critiques, thoughts about languages like Mercury , Curry , Shen in respect to Haskell + miniKanren?

I got interested in Logic Programming and I've found that miniKanren seems to be one of the most widely used projects akin to this task.

I've noticed that maybe a reason for the widespread usage of this projects is due to its inclusion in Clojure 'Core.Logic'.
