Re: [Fab-user] Making env changes persistent to the current session?

[Jorge Vargas]

Hi,

I think I expressed myself wrong. What I want is to have the effect
spawn outside of python. So I can provide a fab command that will
enhance the activate script from virtualenv.

For example:

$ fab activate
$ pip install some_package

and some_package will end up inside the venv as it was activated by
the fabric script.

My goal here will be to replace an equivalent activate.sh that
modifies the state of the current session (in the shell) not in
python.
