Re: [Pydev-code] Code completion

[Dana M. <dan...@ya...>]

Fabio,
good conversation; good points.
After talking w. Aleks, I was planning to use the same strategy he uses
to populate the outline view of the code.
It turns out that he uses Jython to accomplish the introspection of the
Python code within the editor.
Even with that ability, ther eare some issues Aleks feels need
addressing, for example autocompletion of anything in an import
statement. One should be able to do:

import os
os.            # <--- here a list of potential completions occurs

I wasn't really interested in Jython completions anyway, so for now I
don't need to work with that issue.
