POHow do I work with multiple git branches of a python module?
text
Body
copied!<p>I want to use git to allow me to work on several features in a module I'm writing concurrently. I'm currently using SVN, with only one workspace, so I just have the workspace on my PYTHONPATH. I'm realizing this is less than ideal, so I was wondering if anyone could suggest a more 'proper' way of doing this.</p> <p>Let me elaborate with a hypothetical situation: I say I have a module 'eggs', with sub-modules 'foo' and 'bar'. Components in 'bar' use code in foo, so eggs/bar/a.py may 'import eggs.foo'. </p> <p>Say that 'eggs' is in a git repository. I want to try out some changes to 'foo', so I copy it. The problem is that 'import eggs.foo' in eggs/bar finds the original repository in the PYTHONPATH, so it ends up using the old 'foo' instead of my modified one. </p> <p>How do I set myself up such that each copy of the module uses its own associated 'foo'? Thanks.</p> <p>edit- Thanks for the pointer to relative imports. I've read up on it and I can see how to apply it. One problem I'd have with using it is that I've built up a fairly large codebase, and I haven't been too neat about it so most modules have a quick 'self-test' under <code>if __name__ == '__main__':</code>, which from what I've read does not play with relative imports: </p> <ul> <li><p><a href="http://mail.python.org/pipermail/python-list/2006-October/408945.html" rel="nofollow noreferrer">http://mail.python.org/pipermail/python-list/2006-October/408945.html</a></p></li> <li><p><a href="http://www.velocityreviews.com/forums/t502905-relative-import-broken.html" rel="nofollow noreferrer">http://www.velocityreviews.com/forums/t502905-relative-import-broken.html</a></p></li> </ul> <p>The other solution I've been able to google up is to deliberately manipulate sys.path, which seems like an even worse hack. Are there any other possibilities?</p> <p>edit - Thanks for the suggestions. I'd originally misunderstood git branches, so as pointed out branches are exactly what I want. Nonetheless, I hadn't heard of relative imports before so thanks for that as well. I've learnt something new and may incorporate its use.</p>
