Re: Easy install / setuptools

I'm trying to figure out the "best" way to distribute my own python
packages. Basicly, what I want is to have something like an
"installer. exe" (on windows) which puts my package under
Python/Lib/site-packages (so that it can be found via the PYTHONPATH).

I've played around a bit with "easy install" and "setuptools " and the
.egg format. I've already managed to create a "myPackage. egg" file with
setup tools and "install" (it's just a copying) it ito the site-packages
directory using "easy install".
You don't need setuptools at all. Just write a setup.py file using the
standard distutils module, and execute:

python setup.py bdist_wininst

It will create an executable installer. A simple setup.py script looks
like this:

---begin setup.py---
from distutils.core import setup

setup(name='My Package',
version='1.0',
description='Th is is the description of myPackage',
packages=['myPackage'],
)
---end setup.py---

Read the "Distributi ng Python Modules" document in your Python
installation, or at <http://docs.python.org/dist/dist.html>
What I was wondering now is if there's a way to actually EXTRACT the egg
file and put the extracted file (i.e. the .py file) under site-packages.
And not the .egg?
Well... don't use an egg in the first place :)
The problem with egg files is that you can't use
"open(os.path.j oin(os.path.dir name(__file__), 'myFile')" and I'd need to
rewrite such code which I'd like to avoid if possible. Also, I don't
know whether leaving the python scripts packed inside the egg file is
slower for execution or not...
There are many other problems with egg files... (did I menction that I
hate eggs?)

"easy install" usually isn't. It tends to do the wrong thing,
then leave things in a confused state. Too many things have to
be set up right before "easy install" works easily.

"python setup.py" is the de-facto standard.

Yes, there's no really good, standard solution for Python
installation.

It appears that apps distributed as Python Eggs are either a single compressed blob in site-packages directory or a directory under site-packages directory. Is this ALWAYS true? So by just erasing stuff under site-packages I can do a COMPLETE uninstallation of an Egg? Chris

Hello, I have some materials for a project that I am working on that I keep in a source code control system (svn now, but I'm experimenting with mercurial).
