Hello, I would like to extend the debugger with some context-dependent information. I am playing with metalinks and I would like to show, in the debugger, some information if my metalinks are in the selected method. This means that: - I need to add a new presentation in the debugger next to the "variable" and "evaluator" ones. - I need to filter that presentation to show it depending on which method is selected. I tried to extend ProtoObject with a method like: gtDebuggerExpressionMachinViewIn: composite <gtDebuggerPresentationOrder: 21> composite text title: 'My machin'; display: [ :browser :debugger | debugger asString] However, this did not add a presentation in the debugger. It only show up when selecting an object in the debugger inspector (see screenshot). How can I extend the debugger as I want? Thanks Thomas and Guille
