TheReasonedSchemer

Original code from 'The Reasoned Schemer' (MIT Press, 2005) by Daniel P. Friedman, William E. Byrd and Oleg Kiselyov.

This implementation uses an older version of miniKanren. Newer versions of miniKanren have a simpler language, simpler implementation, and improved performance. (For example, condi has been replaced by an improved version of conde which performs interleaving.).

The code is divided into four files:

mk.scm contains the miniKanren core forms.

mkextraforms.scm contains run* and project.

mkprelude.scm contains useful helper relations, including the full arithmetic system from chapters 7 and 8.

mktests.scm contains essentially every piece of code in the book, along with appropriate tests.

To run all the tests, simply load mktests.scm in an R5RS-compatible Scheme system:

> (load "mktests.scm")

To just play around with miniKanren, instead load mkprelude.scm.
