fabric-virtualenv 0.2.0

fabric-virtualenv provides Fabric functions for creating virtualenvs on remote servers, as well as installing packages to them, and running other Fabric operations in the context of the virtualenv.

fabvenv.virtualenv(path)

A context manager that performs all nested operations in the context of the virtualenv path.

For example:

>>> from fabvenv import virtualenv
>>> with virtualenv('/home/me/venv/'):
...     run('python foo')

It is highly recommended to use an absolute path, as Fabric’s cd() contextmanager is always applied BEFORE virtualenv(), regardless of how they are nested.

fabvenv.make_virtualenv(path, dependencies=[], eggs=[], system_site_packages=True)

Create or update a virtualenv in path, installing the given packages and eggs.

• path - The path to the virtualenv. This path will be created if it

  does not already exist.

• dependencies - a list of paths or URLs to Python packages to install

  with pip.

• eggs - a list of paths or URLs to eggs to install with

  easy_install. Eggs can be used to speed up deployments that require libraries to be compiled.

• system_site_packages - If True, the newly-created virtualenv will

  expose the system site package. If False, these will be hidden.

fabvenv.prepare_virtualenv()

Ensure a version of the virtualenv command is available on the remote server. If none exists, a standalone virtualenv.py script will be downloaded from the virtualenv github and saved as ~/virtualenv.py.

The virtualenv command that is prepared is available as env.virtualenv.
