Enhancements to virtualenv
Project description
Quick Setup
Add a line like export WORKON_HOME=$HOME/.virtualenvs to your .bashrc.
Add a line like source /path/to/this/file/virtualenvwrapper_bashrc to your .bashrc.
Run: source ~/.bashrc
Run: workon
A list of environments, empty, is printed.
Run: mkvirtualenv temp
Run: workon
A new environment, temp is created and activated.
This time, the temp environment is included.
Path Management
Sometimes it is desirable to share installed packages that are not in the system site-pacakges directory and which you do not want to install in each virtualenv. In this case, you could symlink the source into the environment site-packages directory, but it is also easy to add extra directories to the PYTHONPATH by including them in a .pth file inside site-packages using add2virtualenv.
Check out the source for a big project, such as Django.
Run: add2virtualenv path_to_source.
Run: add2virtualenv.
A usage message and list of current “extra” paths is printed.
