I've looked at it, but I can't get to reproduce it. I have trouble finding an entry point to start understanding.

Hi.

One possibility is to follow BytecodeDebugger approach. Try to look how it
is implemented

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
