[IronPython] [wingide-users] Using Wing IDE with IronPython - autocomplete for .NET objects (PI file generator)

Attached is an updated script for generating PI files to provide
autocomplete on standard .NET objects.
It now handles all the standard .NET member types (including static
properties, enumeration fields, indexers, events and so on).
It also recurses into sub-namespaces generating new pi-files for all of
This script is hardcoded to add references to, and then generate PI
It generates 90 pi files (90 namespaces) taking up 24mb! The
autocomplete it provides is awesome though. :-)
I had to do a fair bit of violence to the standard generate_pi.py script
so I *doubt* it is desirable to merge it back in. Obviously very happy
for this to be included with Wing if you want, or merged if you think it
is worth it. Is it ok for me to offer this for download from my site? If
I make further changes I will email this list.
The big thing to add is the return type for methods.
Is it possible to specify return types for properties? (Currently any
attribute without an obvious parallel in Python I have turned into a
property in the PI files).
The only real caveat with the current script (that I am aware of - bug
reports and contributions welcomed) is that None is a common enumeration
field member. This is invalid syntax in Python, so I rename these to None_.
There are quite a few minor changes sprinkled through the code - plus
the __main__ part of the script is very different. I have tried to mark
changes with a # CHANGE: comment, but it should be relatively amenable
to diffing anyway...
For reference I was using IronPython 2.0.1, with .NET 3.5 installed and
Wing 3.2beta 1.
All the best,
