I implemented XGP, an IDE for gprolog on the mac, that is implemented *in* gprolog. It runs fine. Menus, Windows, Graphics (drawing pictures); all done in gprolog as extended by XGP.

I make very slight use of globals - I would recommend parameter passing for state or asserting/retracting clauses where feasible. The parameter passing approach makes the best use of the prolog execution model with its semi-magical heap garbage collection.

I use the DCG notation a lot in various programs where I want to pass a context around among a collection of predicates.

I am looking for an alreay-built set of resources to be able to draw and paint to the screen and save to files from within Prolog itself, but I'm on Linux. Any chances XGP  and perhaps gprolog/SDL2  will be adapted to Linux in the future?
