Does PIE allow you to define your own predicates?
Posted: 24 Sep 2019 18:25
Hi,
I'm able to run the standard predicates that PIE exposes, but can't type in any new facts, like
person(sally).
or
likes(karen,jeff).
, it just reports an unknown clause.
PIE doesn't take domains and predicates directives, like Visual Prolog. It seems like standard Prolog. But I can't figure out how to add facts.
What am I doing wrong?
