Cool effort.
One thing that I noticed in Rails when I downloaded it this weekend
was how you installed plug-ins. Very easy. There are various 'sources'
that can be loaded up which work, I assume, in a similar manner to how
you can point easy_install at a web page and tell it 'find links'.
To install a plugin into an application instance (similar to a Zope
instance home), it's just an effort of:
$ script/plugin install acts_as_taggable
The plugin is found, and installed in the instance home equivalent.
This uses 'gems' under the hood from the looks of it, and adds in the
knowledge of a Rails application layout. It was pretty gratifying,
being able to start adding in functionality so easily.
I think a good goal would be to have something like this: A Zope
instance home aware package/egg loader, so that in an instance home
you could add in packages like this:
$ bin/package install zc.catalog
$ bin/package install hurry

During the Zope3 sprint following PyCon, Paul and I, with Jim's
guidance, began work on exploring how Zope can utilize eggs and be
packaged using eggs. Since we're still experimenting with how eggs
will be used, I wrote a script, zpkgegg, which reads the zpkg
configuration information for a package and generates a standard
setup.py from which an egg and vanilla sdist can be generated.
You can find the script in subversion in the projectsupport project.
For a brief overview of how the script is used, see README.txt (in
http://svn.zope.org/projectsupport/trunk/src/zpkgegg/). The eggs
generated by zpkgegg do not attempt to distinguish between runtime,
testing or development dependencies, so almost all packages will
want zope.testing. README.txt contains a brief example of how to
point easy_install at the appropriate folders so that easy_install can
resolve the dependencies.
Note that at this point we're still experimenting with how we'll use
eggs, so suggestions, feedback and comments are welcome.
Thanks,
