We are about to integrate in Pharo a new member of the Glamorous Toolkit: the GTDebugger. As this is a significant change that might affect your workflow, here is some background information to help you deal with the change. First, you should know that the change is not irreversible and it is easily possible to disabled the new debugger through a setting. However, please do take the time to provide us feedback if something does not work out for you. We want to know what can be improved and we try to react as fast as we can. A practical change comes from the fact that the variables are manipulated through a GTInspector, which makes it cheaper to maintain in the longer run. While the first thing that will capture the attention is the default generic interface, the real power comes from the moldable nature of the debugger. Like all other GT tools, GTDebugger is also moldable by design. This means that we can construct custom debuggers for specific libraries at small costs (often measured in a couple of hundred lines of code). Here is an introductory overview blog post that also includes some links for further reading: http://www.humane-assessment.com/blog/gtdebugger-in-pharo/ Please let us know what you think.
