Hi again,

my recent post "Prolog-Java combo for programming multiagent system?"
solicited a handful of very useful answers (thanks once more). One of the
questions I asked concerned debugging capabilities and strategies for
embedded Prolog engines (especially in Java).

The only explicit answer regarded Amzi Prolog:

"Our new Eclipse IDE provides source code debugging of embedded Prolog
components. So you can run your Java debugger at the same time as the Amzi!
Eclipse Prolog debugger. This lets you use the source debugger on your
compiled Prolog code. You can set breakpoints, single step, see variable
bindings at each level in the stack frame and more."

Perhaps, this simultaneous source debugging capability is not unique to
Amzi! Prolog. Which other Prolog implementations do offer this feature?
Which are other strategies to use when simultaneous debugging is not
possible (eg. I recently read about inspecting embedded SWI-Prolog engine
via socekt connection)?

Thanks for your comments,
Michal
