`Wing Pro <https://wingware.com/>`__ is a Python IDE that can be used to develop, test, and
debug Python code written for `Blender <https://www.blender.org>`__, an open source 3D
content creation system. 

If you do not already have Wing Pro installed, `download it now <https://wingware.com/downloads/wingpro>`__.

This document describes how to configure Wing for Blender. To get started using Wing as
your Python IDE, please refer to the tutorial in Wing's ``Help`` menu or read the
`Quickstart Guide <ref:howtos/quickstart>`__.

Working with Blender
--------------------

Blender 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:

.. python::

  import os
  import sys
  
  # MODIFY THESE:
  winghome = r'c:\Program Files (x86)\Wing Pro ~~MAJOR_VERSION~~'
  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.Ensure()
  
  def runfile(filename):
      if sys.version_info < (3, 0):
          execfile(filename)
      else:
          import runpy
          runpy.run_path(filename)

  runfile(scriptfile)

To use this script:
  
1) Modify ``winghome`` & ``scriptfile`` definitions where indicated to the wing
   installation directory and the script you want to debug, respectively. When in doubt,
   the location to use for ``winghome`` is given as the ``Install Directory`` in Wing's
   About box (accessed from ``Help`` menu).
2) Run blender
3) Press ``Shift-F11`` to display the text editor
4) Press ``Alt-O`` to browse for a file and select this file to open
  
Once the above is done you can debug your script by executing this blender stub file in
blender. This is done using the ``Run Script`` button on the bottom toolbar or by pressing
``Alt-P``, although note that ``Alt-P`` is sensitive to how the focus is set.

Note that you will need to turn on listening for externally initiated debug connections in
Wing, by clicking on the bug icon in the lower left of the main window and selecting
``Accept Debug Connections`` in the popup menu that appears.
