A Tour of Prolog

I think that Prolog will rise again. If you have an hour to kill, check out this video introduction by Markus Triska about what makes Prolog unique: [this video] Recently I have been working on getting Trealla Prolog to run in WebAssembly. Support is quite good now, with an easy-to-use JS library[1], Go library[2], and is now one of the best-supported languages for the Spin runtime[3]. I think it's particularly nice for validations, you can write some simple Prolog rules and run the same code on the client and the server now. I would like to explore this more with a dedicated library at some point. Built-in features like DCGs make parsing/generating all kinds of data trivial. I love it. I think the biggest barrier to Prolog adoption is that it has a really steep learning curve, and most people get burnt by half-assed introductions in college that tick the 'talked about logic programming' box in the syllabus. You really have to think in a completely different way to write a good Prolog program. But, once you get the right mindset, it makes solving complex problems incredibly easy. I don't really buy the argument that Datalog is enough. Most Datalog implementations I've seen hack on a bunch of extensions to do things like list membership. It would be awesome to see some serious effort put into an efficient Prolog-based database. The closest thing I can think of is TerminusDB, which I've never used but I wish I could convince my company to try it out ;). My dream is to have some kind
