Developing on QGIS using OSGeo4Mac

In addition to using this tap to install a QGIS stable formula, you can also use it to fully set up a development environment for an externally built QGIS from a clone of the current development (master) branch of the source code tree.

Note: This setup, though heavily tested, is currently experimental and may change. A more stable and time-tested setup is outlined in the QGIS INSTALL document.

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')

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.

	- Use band nodata value if user does not override it
	- Allow calculating statistics for all geometry types
	- Allow buffer to be applied before calculation
