WingIDE and virtualenv

[percious]

I was wondering if there was planned support for virtualenv any time in the near future.

I keep a very bare-bones python install on my machine and keep all my projects separate.

Because of this I lose a lot of the benefits of auto-complete/source assist, because the packages do not exist in the python which runs WingIDE.

It would be nice to have a 1-to-1 mapping of project to virtualenv, and when I opened a project, it would use that virtualenv's python for the prompt, autocompletion, etc.

Thanks!

I too would like to see this.

What I have discovered (with Stephan Deibel's help of course) is to
start Wing after activating a terminal window in virtualenv.  Then I
also load a python file that sets sys.path to my eggs directories, i.e.

-----------------------
import sys


sys.path[0:0] = [
  '/home/tim/projects/ref_impl_python/TRUNK/oship/src',
  '/home/tim/buildout-eggs/z3c.evalexception-2.0-py2.4.egg',
  '/home/tim/buildout-eggs/Paste-1.7-py2.4.egg',
  '/home/tim/buildout-eggs/setuptools-0.6c8-py2.4.egg',
  '/home/tim/buildout-eggs/PasteScript-1.6.2-py2.4.egg',
   ...
-----------------------

as my Debug File (See the Debug menu).

This file then sets the Effective Python Path (see:Source Analysis Stats
under the Source menu option).

Now this doesn't fix the issue with the Python Shell window but code
completion works perfectly.  I do note though that adding files to my
code in the project doesn't get added to the Source Completion function
unless I restart Wing.

So this solution isn't perfect but it does help to use the wonderful
features of WingIDE.

HTH,
Tim

We'll try to look into it.  I don't know much yet about virtualenv but
it may help, if there is a file that sets sys.path, to set that as the
Main Debug File in Wing since Wing tries to parse the sys.path setting
and use that in analysis for autocompletion/etc.

For the shell, it would only work if there's a way to set the Python
Executable in Project Properties to something that runs like Python.
Is that possible?

if not, another way to deal with that is to import wingdbstub in code
running in the virtualenv, set a breakpoint, and then use the Debug Probe
as the Python Shell.

I just configured WingIde to use <virtualenvdir>/bin/python as the
interpreter, and it seems to work properly...
