[1] I'd actually like it if the PEP defined an uninstall command -
something like "python -m distutils.uninstall packagename". It can be
as minimalist as you like, but I'd like to see it present.
it's already there:
http://www.python.org/dev/peps/pep-0376/#adding-an-uninstall-function
That (at least as I read it) is a function, not a command.
If it is a command, give an example of its use from the command line
for us poor "don't want to research" people. If the following works:
$ python setup.py uninstall some_package
Then explicitly say so for us poor schlubs.
Right, I'll add that. Although it will be a reference implementation
only.
Uninstall as a command feels a little weird. Since "python setup.py
[some-command]" implies that the setup.py contains information about
the distribution that the command is being applied to. So instead of:
$ python setup.py uninstall some_package
It could be:
$ python -m distutils uninstall some_package
Asymmetrical with the install of course.

It could just be:
$ python setup.py uninstall
Except then you'd need to have a complete distribution kicking around
with which to run the "python setup.py uninstall" command just to tell
the uninstall command the distribution name you want to uninstall. But
then with the other uninstall format you could uninstall any
distribution from within any other distribution, which is convenient,
but weird ... e.g.:
$ cd Spam-1.0/
$ python setup.py uninstall Foo
Although even the other version of the command could do weird stuff:
$ cd Spam-1.0/
$ python setup.py install
$ cd ../Spam-2.0/
$ python setup.py uninstall
Which would presumably remove the Spam 1.0 distribution when run from
the 2.0 version of it! Or perhaps this command should only allow
uninstall to be run from a distribution whose name and version match
the one that it was installed from ...
I dunno what the right solution is. My two-cents is either to punt and
only include an uninstall function as currently proposed, or for only
supporting some form of the "python setup.py uninstall" style since I
would guess that the most common use-case for uninstall is: user
downloads a distribution, runs "python setup.py install", tries out
the package, decides they don't like package, then runs "python
setup.py uninstall" to restore their python back to it's original
state. For doing anything more complex than that, people should be
encouraged to use another one of the existing tools for managing their
distributions, IMHO.
