`Wing Pro <https://wingware.com>`__ is a Python IDE that can be used to develop, test, and
debug Python code that is running under `mod_wsgi <http://www.modwsgi.org/>`__.

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 mod_wsgi. 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>`__.

Debugging Setup
---------------

When debugging Python code running under ``mod_wsgi``, the debug process is initiated from
outside of Wing, and must connect to the IDE. This is done with ``wingdbstub`` according
to the instructions in `Debugging Externally Launched Code
<ref:debug/debugging-externally-launched-code>`__.

Because of how ``mod_wsqi`` sets up the interpreter, be sure to set ``kEmbedded=1`` in
your copy of ``wingdbstub.py`` and use the debugger API to reset the debugger and
connection as follows:

.. python::

    import wingdbstub
    wingdbstub.Ensure()

Then click on the bug icon in lower left of Wing's window and make sure that ``Accept
Debug Connections`` is checked. After that, you should be able to reach breakpoints by
loading pages in your browser.

Disabling stdin/stdout Restrictions
-----------------------------------

In order to debug, may also need to disable the WSGI restrictions on stdin/stdout with the
following mod_wsgi configuration directives::

        WSGIRestrictStdin Off
        WSGIRestrictStdout Off

Remote Development
------------------

Wing Pro can work with mod_wsgi code that is running on a remote host, VM, or container. To
do this, you need to be able to connect to the remote system with SSH. Then you can create
your project in the same way as above, using the ``Connect to Remote Host via SSH``
project type.  See `Remote Hosts <ref:proj/remote-hosts>`__ for more information on
remote development with Wing Pro.
