[cl-unification-devel] Newbie Question on logic and CL-UNIFICATION
I'm looking for a (very) simple tool for doing prolog style logical deduction in common lisp. This is just for managing tasks and creating an advanced todo list based on rules. Currently PaiProlog breaks and I don't have the time to read all of PIA to understand what, ether me or it are doing wrong. As an example of what I'm trying to do: (<- (PRODUCER ?X) (TOOL ?X)) (<- (tool "emacs")) (?- (producer "emacs")) Yes (do-all (?- (producer ?x)) Firstly, should I be using CL-Unification for this? Secondly, does CL-Unification support this already? Finally, a simple example of how to do this would be wonderful.

Yes, if you want to build your own prolog/theorem-prover.
Secondly, does CL-Unification support this already?
No. CL-UNIFICATION just does unification. It does not do "deduction" (*)
Finally, a simple example of how to do this would be wonderful.
Sorry. No. Marco Antoniotti (*) I *am* working on (and off) on a Prolog implementation based on PAIP but with CL-UNIFICATION at its core. It is almost there.
