Move south package in subdirectory

[Jannis Leidel <jannis@…>]

Please move the south package at ​http://svn.aeracode.org/svn/south/trunk/ to the ​http://svn.aeracode.org/svn/south/trunk/south/ subdirectory (except of course the setup.py).

The advantages are:

• ability to create a svn:externals directly to the south package
• ​editable installations with pip (which uses setuptools' develop command to create links from the site-packages directory to a checkout of South)

[andrew]

Yes, this came up a while ago in discussions for #25. The only problem is that this would break everyone already using it as a svn external, or even as a checkout.

It's annoying that pip/setup.py develop doesn't support this. I'll have to weigh up temporarily breaking every installation.

After getting an SVN checkout, a dirty trick with some symbolic links seems to do the trick:

(test)/tmp $ svn co http://svn.aeracode.org/svn/south/trunk south

(test)/tmp $ cd south

(test)/tmp/south $ for i in db *.py management tests; do ln -s ../$i south/; done

(test)/tmp/south $ ls -F /tmp/south/south
db@  __init__.py@  management@  migration.py@
modelsparser.py@  models.py@  orm.py@  setup.py@  tests@

(test)/tmp/south $ python setup.py develop

Is it possible to do this in the SVN repository to serve both svn:externals users and those who need pip -e or setup.py develop?

[andrew]

That's reasonably evil, but SVN does support adding symbolic links. It's a possible solution; I also want to try the idea I had of having a special init.py instead so we can _Actually_ move to having it in a subdirectory.

A third alternative, I guess, is to override the 'develop' command in setup.py so it does this first...

[andrew]

Fixed in [197] - I included a special init.py that, when loaded as south, adds the real directory to sys.path and then reloads that as South. Hackish-ish, but it's only for migration (heh).
