I made a debugger for Phoenix.
The linked videos demonstrate how you can hook command or wx.Event and start debugging using the shell (based on wx.py.shell).
If you like, please visit my GitHub Pages and the tutorial!
The documentation can be found here: Welcome to wxpyNautilus’s documentation! — wxpyNautilus documentation
If it works for you, I’d love to hear your feedback.
If it doesn’t work, I don’t know who wrote it…
