[issue83] I wish setuptools would prefer v1.4.1 in binary egg format over v1.4.5 in sdist format when I'm requiring >= v1.1.0

New submission from Zooko O'Whielacronx <zooko(a)zooko.com>: It is often the case that a binary .egg is usable and an sdist is not (when the package requires compiling C or C++ code). Here is an example where this is currently happening: http://allmydata.org/trac/tahoe/ticket/773#comment:7 Tahoe-LAFS requires zfec>=1.1.0. There are two distributions found during build a binary .egg of zfec v1.4.1 for the current platform and python version and an sdist of zfec v1.4.5. Setuptools is choosing the latter, which then fails to build because the C/C++ compiler isn't set up on the target system. If setuptools would prefer binaries over sdists when both satisfy the versioning requirements, then this would be better. ---------- messages: 331 nosy: zooko priority: wish status: unread title: I wish setuptools would prefer v1.4.1 in binary egg format over v1.4.5 in sdist format when I'm requiring >= v1.1.0 _______________________________________________ Setuptools tracker <setuptools(a)bugs.python.org> <http://bugs.python.org/setuptools/issue83> _______________________________________________

Using an egg like a Java jar file - Part 2

I apologize for posting out of my thread, but I tried to "reply" twice to my original thread, and my message didn't seem to appear anywhere. Maybe it's just delayed... Anyway, here goes: All: This may be a duplicate post - I can't see the post I just submitted, so I'm trying again. Thanks for the suggestions. I can't use 2.6 because it isn't installed on the systems where my script will be running. I'm attempting to use the 'eggsecutable' suggestion. How do I get command line parameters passed into my entry point main() function? Code is appended below. setup.py: from setuptools import setup, find_packages setup(name='testme', version='1.0.0', py_modules=['testme'], description = 'foo', author = 'Somebody', author_email = 'somebody(a)foo.com', url = 'www.foo.com', entry_points = { 'setuptools.installation': ['eggsecutable = testme:main',]} ) testme.py: #!/usr/bin/env python import sys def main(input): print 'Command line arguments are ' % input if __name__ == '__main__': main(sys.argv)

Using an egg like a Java jar file
by mhearne808 28 Jul '09

In Java, it is possible to create a .jar file with a main() method embedded somewhere in one of the .class files. It is then possible to run the main() method from the command line something like this: java -jar foo.jar I believe this will work with only one main() defined - if there are multiple ones, then you have to specify the path (internal to the jar file). I gather from previous googling that there isn't a python command line option equivalent to -jar for eggs (although that might be kind of handy) but that you can add an egg to your path without installing it by doing something like the following (in a bash shell): export PYTHONPATH=foo.egg This will then allow you to run a python script at the command line without having to actually install the egg to the normal "site- packages" directory. My questions: - Is it possible to embed a script with a "main" entry point in an egg, and run that from the command line? - If so, how do you pass command line arguments to that main? - Is this a massive abuse of the intended usage of setuptools? Thanks, Mike

As of Python 2.4, you can use 'python -m modulename' to load the named module as the main module. > - If so, how do you pass command line arguments to that main? python -m modulename args... > - Is this a massive abuse of the intended usage of setuptools? Nope. There is also a way to make an egg an executable in its own right; you can declare an entry point 'eggsecutable' in the 'setuptools.installation' entry point group, and when you bdist_egg it, the egg will include a simple #!/bin/sh script header to put the egg on sys.path and run the entry point function. The main downside to this is that the egg cannot be renamed or run via a symlink with another name; you have to run it as foobar-1.2.3.egg.

I have a folder tree of data files. I can't seem to get distutils to recognize "data/*" as data_files (even though it works for package_data). Is there any nice way of specifying that I have a folder of data files? - Pavel Panchekha

setuptools: can I specify different install_requires for different python versions?
by Matthew Wilson 28 Jul '09

28 Jul '09

I have a package that depends on the multiprocessing package, which got added to the standard library as of 2.6. So, for only those people using python versions before 2.6, I want to require they install multiprocessing. Is this possible? -- Matthew Wilson matt(a)tplus1.com http://tplus1.com

Problems with setup.py
by Josh Holland 28 Jul '09

28 Jul '09

I am currently having difficulty with a setup.py script. The problem was originally brought to my attention by someone packaging the project for Fedora 11, but I can reproduce a similar problem on my Jaunty box. When "python setup.py build" is run, the following output is produced (running with -n switch): running install running build running build_py running build_ext running build_scripts changing mode of build/scripts-2.6/suvat running install_lib running install_scripts changing mode of /usr/local/bin/suvat running install_data error: can't copy 'd': doesn't exist or not a regular file This is for me; the Fedora issue is with 's' instead of 'd'. This is with different versions of setup.py. My development version is attached, and the Fedora one is available in the tarball at http://joshh.co.uk/stuff/suvat-0.1.1.tar.gz. -- Josh Holland <jrh(a)joshh.co.uk> (key F6067C12) http://joshh.co.uk dutchie on irc.freenode.net http://twitter.com/jshholland http://identi.ca/jshholland '< KnMn> I am sick of people saying "loling"; surely it should be "lingol"'

What do I need to do to include it? The README is not "package data" because it's not inside a package. You can't install package data in a project that only includes modules. In any case, there's no point in shipping documentation inside an egg, because only your project's *code* will be able to read it, not humans. Human-readable documentation only belongs in a source distribution. Note that, in general, you do not need to distribute eggs for your project. The egg format is intended for plugins and other situations that require pre-built, ready-to-execute binaries. pip, buildout, and easy_install can all build their own eggs on the target system in most cases, so the only benefit to distributing eggs is if you have, say, a C extension module and want to provide pre-compiled versions for Mac OS and Windows. (And for Windows, you can build a bdist_wininst .exe instead; easy_install at least will still be able to use it, and you'll make Paul Moore happy. ;-) (That's an inside joke, don't worry if you don't know who Paul is.))
