cKanren

This library implements miniKanren (http://minikanren.org) with an extensible framework for defining constraints.

How to install

cKanren can be installed as a collection within Racket (http://racket-lang.org) as follows:

• git clone git://github.com/calvis/cKanren.git
• cd cKanren/cKanren
• raco link .
• raco setup cKanren

After setup finishes, you will be able to use miniKanren, #lang cKanren, and all constraint libraries that ship with cKanren.

For users

If you are interested in writing miniKanren programs, you can (require cKanren/miniKanren) for standard miniKanren definitions. You can also require constraint libraries like neq as (require cKanren/neq).

Stable constraint libraries

The following libraries have been tested extensively.

• Tree unification cKanren/tree-unify
• Disequality constraints cKanren/neq
• Finite-domain constraints cKanren/fd
• Nominal logic cKanren/ak
• Absento, symbolo, and numbero cKanren/absento

All other constraints libraries are experimental.

For constraint writers

Documentation of cKanren is available by running raco docs cKanren.
