Class advisors in Python 3
Hi, Does class advisors like 'implements' and 'adapts' are going to work in Python 3 ? If not, should we discourage its usage now ? Regards, Baiju M

Regardless if they work or not I would love to have a decorator version of them. Wichert.

They won't work anymore. zope.interface contains 2to3 fixers to rewrite them to a class decorator syntax IIRC. Hanno

Wow, that's really nice. BTW, does Python 2.7 support class decorators already? If so, we could slowly migrate code to that syntax without having to go Py3 all the way. Regards, Stephan -- Entrepreneur and Software Geek Google me. "Zope Stephan Richter"

Class decorators were introduced in Python 2.6. I think it's going to be a whole before we can require 2.6 as a minimum version. Hanno

ZTK 1.1 deprecates Python 2.4 *and* 2.5. So, 2010-12-31 is the last day for their official support. Charlie -- Charlie Clark Managing Director Clark Consulting & Research German Office Helmholtzstr. 20 Düsseldorf D- 40215 Tel: +49-211-600-3657 Mobile: +49-178-782-6226

Who told you that? We documented our decision at http://docs.zope.org/zopetoolkit/process/python-versions.html. Python 2.5 is nowhere close to being deprecated. Hanno

It was decided at the same time as the decision was taken to drop support for Python 2.4. I don't remember anyone speaking up to support Python 2.5 and syntactically there is little between 2.4 and 2.5. Moving the baseline to 2.6 will allow the smooth introduction of exactly such Python 3 compatability. But, at the end of the day, the decision is with the ZTK group.

Actually, it's in zope.fixers. :) And it's only implements() -> @implementor i think. Adapts come with zope.component which isn't ported to Python 3 yet, but the same thing should happen there, yes. -- Lennart Regebro, Colliberty: http://www.colliberty.com/ Python, Zope, Plone blog: http://regebro.wordpress.com/ Telephone: +33 661 58 14 64
