The NanoProlog package

[ Tags: bsd3, language, library, program ] [ Propose Tags ]

This package was developed to demonstrate the ideas behind the Prolog language. It contains a very small interpreter (Language.Prolog.Nanoprolog) which can be run on its own. It reads a file with definitions, and then prompts for a goal. All possibe solutions are printed, preceded by a tree showing which rules were applied in which order.

The file contains a description of part of the Dutch royal family, whereas the file shows unification at work in a very small type inferencer.
