Ciao Playground debugger looks quite cute now! (Was: Prolog Necronomicon: Write an Interactive Debugger!)

Hi,
Just click on the "Ladybug":
https://ciao-lang.org/playground/
Somehow the source highlighting
during debugging works better than in SWISH.
Bye
P.S.: Now I am drawing inspiration.
So in the top-level answer substitution
there are no debugger options, and it
goes back to creep? Well thats also possible.

 We recently started porting formerly Jekejeke
Prolog to the 100% Prolog Novacore from Dogelog
Player. The current state is that formerly Jekejeke
Prolog is now 50% Prolog, and we are continuing
the transformation.
 Formerly Jekejeke Prolog did have a natively
written Interactive Debugger. Dogelog Player
does not yet have an Interactive Debugger. So we
started an experiment of writing a non-native
Interactive Debugger.
 Our pathological examination of formerly Jekejeke
Prolog lead to an Interactive Debugger that can
handle cuts, but that is also smart enough to
switch from 4-Port model to 2-Port model. We will
mostlikely ship it, despite some loose ends like
hiding system and library details.

Dogelog Player is a Prolog system that is written
in 100% Prolog. Formerly Jekejeke Prolog was a
Prolog system that was written in 100% Java. We
created a new version of Jekejeke Prolog that
has 50% Prolog from Dogelog Player and is
still multi-threaded.

We trashed everything beyond the core of Jekejeke
Prolog and adopted the Dogelog Player libraries
and top-level, even library(markup) works! The
new Jekejeke Prolog is significantly slower than
Dogelog Player, almost a factor two. But it can still
serve for some cherry picking.
