IIRC SWI-Prolog can be embedded in Python if that's your thing. Interfacing with Scryer Prolog might be require a bit more but ought to be doable, and if they haven't surpassed SWI in some performance metrics yet I'd be surprised.

I'm kind of a lisper but I find it easier to get things done in a proper Prolog than the kanrens.

It hasn't been merged into the main branch yet, but you can embed Scryer in Python now[1], and it's quite enjoyable. I've also embedded in Java, Clojure, and elisp[2] :)

The Clojure one is bundled up into a library called libscryer-clj, which I haven't released yet, but it operates the same way as libpython-clj[3], libjulia-clj[4], and libapl-clj[5].

As an aside, Scryer is hella ergonomic. clpz+reif is an amazing and amazingly powerful combination, and Scryer's DCG philsophy over double quoted strings is chefs kiss -- it really delivers on the original mission of Prolog. Ediprolog[6] is a fantastic REPL for Emacs.

And honestly if you haven't seen Marcus Triska's work[7], by God you are missing out on one of the true joys of life.

I was going to mention how cool JJs work is. Upvote to all those links.

Nah dude YOU are awesome! I'm just embedding the work other smart people did haha.

Ah, nice!

Yeah, I really like Scryer, it's been my goto Prolog for quite some time.

You wouldn't know a way to get it working under Termux on Android? I tried to build it a while back but got inscrutable compiler errors and didn't follow through. Maybe building Trealla would be easier, since it's implemented in C.

I'm also enjoying http://tau-prolog.org/.

Trealla and Tau are both wonderful. Very close cousins of Scryer.

I've never tried compiling on rust before but open an issue or a discussion on the Scryer board and maybe we can figure it out!

*clarification-- it's written in rust, never tried compiling rust for android before

I was/am also anticipating performance gains from Scryer. Which is why I made a point to request up to date Scryer benchmarks in the SWI forums. Still, for free/open Prolog, SWI-Prolog is hard to beat: https://swi-prolog.discourse.group/t/porting-the-swi-prolog-...
