Interesting. I would say that *something* in the

Where I would like to use my system's standard packaging solution (I'm
on Windows, so I mean the Windows Add/Remove Programs control panel
applet here, as supported by bdist_wininst or more recently
bdist_msi), I am being required to use a different mechanism.
Right, but this is an issue on a different metalevel. Nobody is proposing
that Debian users install eggs directly into their
/usr/lib/python2.x/site-packages directory.
Like David, I don't like anything other than the "official" (ie,
Windows installers in my case) mechanisms having access to the Python
installation directory.
If there was a way of building a Windows installer that installed
packages in "egg" form, so I didn't have to use setup.py at all when
installing, just double-click on the installer, that would suit me.
This feels like what the Debian people want with their .deb format as
well.
Right - this would hopefully be covered at some point using an .msi or .exe
wrapper for eggs on Windows. So far, though, you're the only person I've
heard from about wanting this on Windows, versus the number of people who
want it for e.g. Debian. So I'm still considering Debian wrapper support
as being more urgent than .msi wrapper support.
My point to David was simply that egg packaging in the .egg form is more
akin to Stow than to CPAN, so most of the flaws of CPAN are not applicable
to them.
The wording I'm using here is possibly not accurate - there seem to be
a confusing mix of concepts and ideas going round, with no-one having
a good understanding of all of them. My apologies - if there's a good
glossary somewhere, which explains what to call things like
* The executable I click on in Windows to install something
* The .deb file that a Debian user downloads and installs
I would call these "system packages", to distinguish them from Python
packages. You (and others) would like to ensure that any project you
install is wrapped in a system package.
* The set of files that end up in Python's site-packages
A "project distribution", or just a "project" (which is a less accurate
term but more convenient).
- for a "normal" install (bdist_wininst, non-egg, whatever)
This has never seemed to me to need a special term unto itself, so I don't
have one.
- for an egg
An egg. :)
- that comprises the difference between the above two ( :-) )
Egg metadata. An egg is just an installed project distribution that
includes egg metadata, in one of the three possible layouts for putting
that metadata alongside the rest of the project contents.
