In this simple program: % [link] % P01 (*): Find the last element of a list % my_last(X,L) :- X is the last element of the list L % (element,list) (?,?) % Note: last(?Elem, ?List) is predefined my_last(X,[X]). my_last(X,[_|L]) :- my_last(X,L). % ========================= end program... more »

Why prolog is by far the best, most productive, easiest programming language First of all I will only advocate the use of pure prolog - that means no recursion, lists, forall's, and any other features. Extra features that were added destroy the whole point of the elegance of prolog. A prolog equivalent is pervasively used everywhere right under... more »

Hi all, Not sure if this is really appropriate for the newsgroup, it really is quite deep in the implementation details of SWI-Prolog. I've got my version of python bindings for SWI-Prolog working quite well now, and have an RDFLib store built upon it. It works for basic values of "work". Code at [link]... more »

SWI, Notation 3, C and Python
|
| |
I've been experimenting a bit with SWI Prolog, and have made some Python bindings using Cython, mostly to learn a bit about how SWI works. I arrived at this looking at Notation 3, with quoted graph support and trying to figure out how to bolt inferencing support onto rdflib, a commonly used RDF library for Python.... more »
