``v`` is a tiny utility for managing python virtual environments.
Calling ``v`` will open a new shell that will use a virtualenv, skipping the `activate` or `workon` scripts. It will call the ``mkvirtualenv`` and ``activate`` scripts that virtualenvwrapper_ uses if they exist.
v [name] [python]
By default, ``v`` will create a new virtualenv in ``~/.virtualenvs/default`` and then
start a new shell inside it. The `name` argument is the name of the virtualenv to use, and will default to ``default``. The ``python`` argument is a python version to use, and will use the system's python by default. It is not needed when activating a virtualenv.
The default name, python and home directory can be overridden with ``$V_DEFAULT_NAME``, ``$V_DEFAULT_PYTHON`` and ``$V_HOME``. The home directory will fall back to the value of ``$WORKON_HOME`` (used by virtualenvwrapper_) and then ``$HOME/.virtualenvs``.
'Deactivating' the virtualenv is as simple as exiting the shell (`exit` or `ctrl-d`), returning you to the shell you we using before.
Install ``v`` to ``~/.local/bin/v`` with:
.. code:: bash
pip install --user v
You may need to add ``~/.local/bin`` to your ``$PATH``.
``v`` supports a limited set of the hooks provided by virtualenvwrapper_. Hooks are looked for in the current ``$V_HOME`` directory when ``v`` is run. ``premkvirtualenv`` and ``premkvirtualenv`` are sourced immediately after a virtualenv is created (nothing is run between them). ``preactivate`` is run before exporting the virtualenv environment variables, and ``postactivate`` is sourced just before the new shell is started.
Running the tests requires tox_ (which installs the package) and bats_ (which checks the script can be run)::
