venv-activate

Bash tab completion of creation and activation of Python virtual environments (installed under $HOME/.venvs by default)

Installation

If _venv-activate.sh is installed at /opt/_venv-activate/_venv-activate.sh then if the following is added to a user's ~/.bashrc

# Enable tab completion of Python virtual environments
if [ -f /opt/_venv-activate/_venv-activate.sh ]; then
    _VENV_ACTIVATE_HOME="${HOME}/.venvs"
    _VENV_ACTIVATE_PYTHON=$(which python3)
    . /opt/_venv-activate/_venv-activate.sh
fi

then a user can tab complete for possible Python virtual environments to activate with venv-activate (assuming that the path of VENV_ACTIVATE_HOME actually exists).

Example

$ venv-create data-science

results in

(data-science) $ python -m pip install --upgrade pip setuptools wheel

# Created virtual environment data-science

# To activate it run:

venv-activate data-science

# To exit the virtual environment run:

deactivate

and then

$ venv-activate #tab

results in

$ venv-activate
data-science

and tab completing data-science and hitting enter then activates the virtual environment

(data-science) $

API

venv-create

Create a new Python virtual environment.

$ venv-create sandbox

(sandbox) $ python -m pip install --upgrade pip setuptools wheel

# To exit the virtual environment run:

deactivate

venv-activate

Activate an existing Python virtual environment.

$ venv-activate sandbox
(sandbox) $

venv-remove

Remove an existing Python virtual environment by deleting the venv directory (which holds the Python runtime and installed packages).

$ venv-remove sandbox

# Deleted virtual environment sandbox

venv-info

Show version information for Python and pip, and how many packages are installed inside the Python virtual environment.

$ venv-info sandbox
