The 9th and 10th of November was the Scryer Prolog Meetup 2023 in Düsseldorf. As a Scryer Prolog user and contributor, I was very excited to go to this meeting. Now, I'm back at home and I can write here a report of what happened in this event with the notes I've taken.

Difference Lists are a very powerful and useful tool. They're also difficult to understand and can result in difficult to read code. In this post we'll address both of these issues.

Prolog programs have both logical and procedural meanings. In this post we'll take a look at procedural ideas more commonly associated with functional programming than Prolog, namely: map, filter and reduce (foldl and foldr). We'll code them and then query them.

Three Prolog fundamentals that I wish I'd understood earlier

In the process of developing a fairly large SWI-Prolog project, I've developed some experience at using PlDoc — which actually goes beyond being an automated documentation system, doubling as an integrated development environment — and PlUnit, which I'll share here.

Transitive relations show up a lot in AI code, in this post we look at a couple of ways to code them that depend on what you can assume about your domain and what Prolog you're using.

After "Hello, world!" it's typical to write a program that asks the user's name and greets them. In this post we learn how to do this in SWI-Prolog without requiring a full-stop.
