Virtualenv

The virtualenv.el extension is quite useful in the standard python development process.

It is implemented in a “natural” way, it emulates the `virtual/bin/activate` script setting up the environmental variables as the original virtualenv package does. In this way you can type shell commands with the modified paths of the virtual environments.

To activate a virtualenv just type the command:

M-x virtualenv-activate

And select the virtual environment directory, it will setup the necessary environment variables.

To deactivate the virtual environment (activating another virtualenv
deactivates the current automatically):

M-x virtualenv-deactivate

To barf which virtualenv is active at the moment:

M-x virtualenv-current

You can also use a virtualenvwrapper-like activator:

M-x virtualenv-workon
