#prolog people: Do you have a favorite online IDE for a few days of in-class work? I'll open the bidding here:
https://www.tutorialspoint.com/execute_prolog_online.php
It looks like you put your knowledge base in the main.pg tab, put your queries in the STDIN tab, and hit Execute. (Interactive would be nicer.)
@peterdrake Update: I have looked around. Nearly every online IDE I have found for Prolog is at best like the TutorialsPoint IDE, and a lot of them are even more primitive.
