[Zope3-dev] eggs for Zope 3 extensions
Hi there, I know there are lots of ideas about eggs in Zope 3 land, so I'd like to pick the brains of the people who have looked into this more than I have for a bit. First to say what I'm not talking about: I'm not talking about eggifying Zope 3 itself. This is a valuable project but hopefully mostly independent of what I'd like to do. There are a whole bunch of interesting Zope 3 extensions that I'd like to use in a project, such as some of the various zc.* packages. Imagine they've been turned into eggs. Now my project wants to use them. What's the Zope 3 pattern for this, if any? The project needs to have some way to do the following: svn co myproject cd myproject make where 'make' creates a Zope 3 installation, and downloads all the eggs listed as requirements for this project from the net, and installs them so that the Zope 3 instance actually picks them up. In particular, are there any ideas of how the -configure.zcml and -meta.zcml files would end up being generated and installed in package-includes? Eggs do not provide for this directly, but perhaps there are some ideas about Zope 3 specific eggs that do?

Right, I can make it work, I just wondered if there was some canonical way. :) | In particular, are there any ideas of how the -configure.zcml and | -meta.zcml files would end up being generated and installed in | package-includes?

As far as I understand them, Zope 3 would need to be able to understand entry points before I could use these in a project that uses Zope 3, right?

Extensions that contain ZCML or other file-based resources (page templates, ZConfig schema components) cannot currently be used directly from a ZIP file. I started work to support that on the zipimport-branch, but didn't have time to finish the proposal that went with that. That branch allowed ZCML and page templates to be loaded from within ZIP files, and support code to allow packages to refer to their own resources abstractly, even without the egg-support code being available. The changes on that branch work with ZIP-based imports generally, and are not specific to eggs (but I think they work fine with eggs).
