There are several references around the web saying this will be part of distutils2.

Our developers depend on it.. Is this going to be in a release soon?

Thanks,

This is correct. I mentored the student who worked on this for the
Google Summer of Code 2012; the code is mostly ready, but due to other
commitments I haven’t yet finished it.

The fourth alpha was released yesterday to let people at PyCon try out
distutils2; more alphas should follow regularly, so develop will
probably be included in a released version in March or April. You can
follow http://bugs.python.org/issue8668 to track the progress of this
feature.

BTW, I’d be interested to know how you’re using develop (you said you
“depend on it”, so I assume you’re using it in a way that you can’t
emulate with pth files or PYTHONPATH).

Would "pip install -e ." work for you?

how would you emulate this scenario
http://qwcode.blogspot.com/2012/01/multilpe-projects-in-develop-mode.html

if you want to "develop" install a pkg that has dependencies, and the
dependencies to be installed normal,
Is there an easy emulation for that w/o basically just rewriting it?

well, currently "pip -e" just calls "setup.py develop"

I see. In that case I concur, the develop command is an absolute must.

Ah, obviously! Thanks for replying. So PYTHONPATH works for some
limited cases, but develop will have these advantages:

- permanent
- install dependencies
- creates the dist-info directory
- more?
