Until something better comes along, I’ve uploaded a refined version of the example above on GitHub, along with documentation and installation via pip/PyPI, licensed under MIT, available here:
- https://github.com/mottosso/iscompatible - http://iscompatible.readthedocs.org I adapted the documentation to include the same requirements as the Rez example, posted above, so we can compare between them. Basic usage $ pip install iscompatible $ python >>> from iscompatible import iscompatible>>> iscompatible("foo>=5", (5, 6, >>> 1))True>>> iscompatible("foo>=5.6.1, <5.7", (5, 0, 0))False>>> MyPlugin = >>> type("MyPlugin", (), {'version': (5, 6, 1)})>>> iscompatible("foo==5.6.1", >>> MyPlugin.version)True Best, Marcus On 9 October 2014 08:30, Marcus Ottosson <[email protected]> wrote: > Here's a little more details regarding the specific requirements I'm > looking for. > https://groups.google.com/forum/#!topic/pyblish/qCgYvlIi3WE > > On 9 October 2014 08:21, Marcus Ottosson <[email protected]> wrote: > >> Chad, are you familiar with the requirements.txt >> <https://pip.readthedocs.org/en/1.1/requirements.html> syntax?
