Wait a little bit, and it's gonna be even worse, now that buildout
and pip seem
to become popular. For example, the TurboGears people are
considering switching
from setuptools to pip...
Tarek is now doing a lot of very useful work on distutils (thanks
Tarek!), but
I'm not sure it'll be enough to stop people from converting to
whatever of the
many build/packaging systems which have been popping up recently.
Combined with
the current trend that everything must be exploded into lots of
interdependent
but separately packaged libraries (the paste/pylons syndrome... try
pulling
something like TurboGears2 and see how many third-party packages it
installs), I
fear this is going to generate a very painful user/developer
experience :-(
From my perspective (the Python web community), setuptools has been a
great uniter of community.
By making it easier to break-up large projects into smaller
distributions, it's now reasonable to share more code between more
developers. This is an important philosophy of TurboGears 2, in that
they're bringing together different pieces of Python web parts and
composing them into a single framework. I think it's great that when
I'm working on a Zope-based project I can participate in packages
produced by the non-Zope ecosystem. This builds much greater bridges
across sub-communites than smaller barriers put up such as one project
using pip and another using easy_install. Heck, even when only wanting
to share code between a couple personal projects, the barrier is now
low enough that it's reasonable to package up that code and share a
distribution, when in the past the only way to share that code was
nasty copy-n-paste.
Yes, there is pain in learning to use these tools, but it's mostly a
documentation issue. Once you've learned the tools, it can be very
easy to manage a very large amount of packages. Thanks to Buildout
(luuuuuv the Buildout!) it's so much easier today to deploy a Zope-
based application today than it was 5 years ago, even though a Zope-
based application 5 years ago used a single monolithic Zope
distribution and a Zope-based application today is composed of many,
many smaller distributions. I'm very happy that I can so easily
incorporate 3rd party libraries into my projects, it makes for a very
pleasant developer experience :-)
