Auto-VirtualEnv is a small bash script that automatically initializes a Python virtualenv once you get inside a directory.
The first step is to define where your virtualenvs will reside. You will need to create a directory for that and then add it on your startup files (for example, ~/.bashrc). To do that, simply add a line with
where <directory>`` is the directory for the virtualenvs.
Next step is getting the auto-virtualenv.sh file (really, all you need is that file) and saving somewhere in your disk. Then add the following in the end of your ~/.bashrc:
source <path where auto-virtual.sh is>/auto-virtualenv.sh
And that's it!
To auto-load a virtualenv, you'll need to tell that the directory belongs to a virtualenv. To do so, create a file named .venv inside the current directory with the name of the virtualenv and, every time you get in this directory (or any of its children), the virtualenv will be activated automatically.
There are two other tools included in auto-virtualenv.sh:
mkenv will create a virtualenv (inside your WORKON_HOME) and automatically create the .venv in the current directory.
venv will activate any virtualenv without the need of passing the full path (as long as the virtualenv is inside WORKON_HOME).
