Debugging QGIS 3.x python plugins on OSX using VS Code

Plugin

In QGIS install the plugin debugvs.

Python dependencies

The debugvs plugin needs the python module ptvsd to function. This module is not installed by default.

In principle you just pip install ptvsd in the python interpreter used by QGIS.

Based heavily on this old guide by TimLinux http://linfiniti.com/2012/09/remote-debugging-qgis-plugins-using-pycharm/

• In PyCharm click menu "Run -> Edit Configurations" (Or click Edit Configurations in the dropdown in the toolbar)
• Click the plus to add a new "Python Remote Debug" config
• Name the config. Use port 53100 (Could probably be any high port)
• Add to the python code:

import sys
sys.path.append('/Applications/PyCharm.app/Contents/debug-eggs/pycharm-debug.egg')
