import d
import d
Hi everybody, while I'm still thinking about writing the import manager, here is a patch that implements the walk-up-the-hierarchy import scheme that got so much positive feedback. I'm intending to use this implementation as proof of concept for the switch to my new package structure, but wouldn't mind seeing something like it the distribution as well ;-) It changes the default import mechanism to work like this: try a.b.c.d try a.b.d try a.d try d fail instead of just doing the current two-level lookup: try a.b.c.d try d fail As a result, relative imports referring to higher level packages work out of the box without any ugly underscores in the import name. Plus the whole scheme is pretty simple to explain and straightforward. Since the patch is so small, I attached it to this mail. Hope you don't mind. The ZIP archive also contains a sample package which demonstrates the feature. Run Python with -v flag to see how the new scheme works. Feedback is most welcome. I am especially interested whether the scheme breaks any existing packages. -- Marc-Andre Lemburg ______________________________________________________________________ Y2000: 81 days left Business: http://www.lemburg.com/ Python Pages: http://www.lemburg.com/python/
Strange... I would have thought that this new patch would stir up some cheers or opposition. Has anyone tried it in some real apps ? It would be interesting to see whether it breaks any code in e.g. packages such as Pmw, PIL, Zope's packages or NumPy. It doesn't break anything for my packages or apps.

Not yet, but this looks better as a default search path.

JimF, /F, Guido and other package maintainers could do you a favor by trying your patch ;-) and give us some real feedback on this. -- Vladimir MARANGOZOV | Vladimir.Marangozov@inrialpes.fr http://sirac.inrialpes.fr/~marangoz | tel:(+33-4)76615277 fax:76615252
