I would argue the other way. Why force authors of console
scripts to
deal
with entry points instead of just installing the script as-is?
Please explain "as-is" with reference to ensuring that the script
works cross-platform. I think the benefit of entry points for
scripts
is that it generates appropriate wrappers to allow use on all
platforms.
I write a python script call hello.py like this:
#!/usr/bin/env python
def main():
print 'hello!'
if __name__ == '__main__':
main()
Why make me define an entry point for that? I can just put it in
/usr/bin or somewhere in the path on Windows and call it as
"hello.py".
Does setuptools give me something extra for Windows? I'm not a
regular
Windows user, so it's likely that there are features I don't know
about.
Yes. It creates a .exe wrapper [1]. By using entry points, I don't
need
to care what the target system is. Also, /usr/bin/env might invoke
the
wrong python.
Exactly: using entry points for console scripts guarantees that the
python into which the corresponding distribution is installed is the
one
used to run the script, which is *highly* desirable. Otherwise, you
end
up with the "just install everything in the system Python's
site-packages" mess.
pip installs my scripts into a virtualenv without any issue and
without using entry points, AFAICT.
I guess if we move to requiring entry points and disallowing simple
script distribution I'll need to find another way to package
virtualenvwrapper. Since it's a bash script, it doesn't have entry
points. I've been using setuptools to package it so it can be
installed via easy_install, since it is a Python development tool.
