Introduction

Blender's loads Python scripts in a way that makes them difficult to debug in a Python debugger. The following stub file can be used to work around these problems:

import os
import sys

# MODIFY THESE:
winghome = r'c:\Program Files\Wing IDE 2.1'
scriptfile = r'c:\src\test\blender.py'

os.environ['WINGHOME'] = winghome
if winghome not in sys.path:
    sys.path.append(winghome)
#os.environ['WINGDB_LOGFILE'] = r'c:\src\blender-debug.log'
import wingdbstub
wingdbstub.debugger.StartDebug()

def runfile(filename):
    execfile(filename)
runfile(scriptfile)

To use this script:

Once the above is done you can debug your script by executing this blenderstub file in blender. This is done using File -> Run Python Script from the bottom menu or by the Alt-P key, though Alt-P seems to be sensitive to how the focus is set.

Note that you will need to turn on passive listening for debug connections in Wing, which is most easily done by clicking on the bug icon in the lower left of the main window and selecting Enable Passive Listen in the popup menu that appears.
