Many of the Smalltalks allow hooking to a running image to do live debugging.


No they don't. They just allow for fix and continue; they give you no insight into why a problem occurred because they provide no history.


uhm... that's not universally true - I worked with some folks that had the history when they did it. Not sure if it was vendor provided or home grown, but it was the call history and call stack.


Call stack is provided in most debuggers these days. Are you honestly saying you saw something comparable to the linked article in some Smalltalk system? If so, I would be very interested in some kind of reference.


It was a VMWare debug image and it had all that information although it was not as fancy. It did have a good amount of custom code.
