comparing version strings?
Hi All, Is there any any in setuptools/distutils/anything else that I can use to compare version strings using the same rules as setuptools? ie: sort the following list of versions: 1.0 2.0dev-r22542-20100623 2.0dev-r22553-20100624 2.0 ...etc cheers, Chris
Hello Chris, See: from distutils.version import StrictVersion and svn://svn.zope.org/repos/main/Sandbox/adamg/zope.wineggbuilder/trunk/src/zope/wineggbuilder/build.py Friday, June 25, 2010, 11:34:59 AM, you wrote: CW> Hi All, CW> Is there any any in setuptools/distutils/anything else that I can use to CW> compare version strings using the same rules as setuptools?

Chris, You also can use the distutils2.version module. I've documented them in my fork [1], waiting to be merged upstream for now, but the codebase of the first (alpha) release of distutils2 [2] ship with the distutils2.version module. This respect version specifiers as described in PEP 354 [3], and I think it's the good way to compare version numbers for the future. Hope it helps, bug reports and/or any feedback is welcome !

Yes, this is good, but since we're using setuptools, I *really* want to compare versions in exactly the same way that it does, for better or worse... I guess I need to go and read the setuptools source, unless anyone has some easy answers for me? cheers, Chris -- Simplistix - Content Management, Batch Processing & Python Consulting - http://www.simplistix.co.uk
