Scryer Prolog distribution via pkgx

[Kapelianovych]

Hello.

I managed to create a Scryer Prolog publishing configuration for pkgx package manager a while ago and decided to share that with the community.
For those who does not know, this manager does not require to install packages into the root or user space, instead you initialise a dev environment where you need it (usually in root project folder) and pkgx will download and cache all needed binaries and make it available just in that folder. Pretty non-standard approach but I like it. And I wanted to make Scryer Prolog available there to use it (apparently I grew quite fond of Prolog).

So, if you don't have pkgx installed in your system, you can do it like that:

brew install pkgx || curl https://pkgx.sh | sh

Then run:

pkgx dev integrate

This command should be run only once. Usually you do it right after installation and forget about it completely 😊

Now, you are able to bootstrap dev environments and use Scryer Prolog (and many more packages). To do that, create a folder or go to an existing one with some Prolog code and create the pkgx.yaml file with the following content:

dependencies:
  scryer.pl: 0.9.4 # use the desired/needed version

And then run:

dev

The last command has to be run only once ever. That is it. After that whenever you cd into this folder you will be able to use the scryer-prolog binary.

I hope this will be useful to those who use pkgx and love Scryer Prolog.
