This is an interesting idea. I am using pydev now, and I'm relatively new to that environment, and I am wondering if there's a similar way to hook into pydev's debugger.

showell: I don't know if this has changed, as I haven't used Eclipse for a couple of years, but from what I can recall all you have to do is make sure the pydev directory is in your Django application's python path. i.e., put this: 

import sys; sys.path.insert(0, '/path/to/pydev')

below the line: 

from django.template import Library, Node

in this snippet.

Hope this helps.

(Note, I bet it'll work with WinPdb as well)

See http://www.djangosnippets.org/snippets/1571/ for a pydev variation. jsandell, it seems you don't need to actually add pydev to the path if you launch your app using pydev's debugger.
