Command reference

List of commands

install

vpip install [-g | -D] [PACKAGE [PACKAGE ...]]

Install packages and save to the dependency.

By default, the package would be installed to the local .venv folder, and the package name would be add to the install_requires option in setup.cfg.

The version range of the development dependency is pinned and the version range of the production dependency is specified in a compatible range.

When PACKAGE is not specified. The tool will install all dependencies to the local venv. It executes two commands:

pip install -r requirements-lock.txt
pip install -e .

PACKAGE can also be a URL but it will only work with -g flag.

Options:

  • -g, --global - Install packages to a new venv in ~/vpip/pkg_venvs. Executables would be linked to the Python Scripts folder so you can still access them from the command line.

  • -D, --save-dev - Save the package to the development dependency.

uninstall

vpip uninstall [-g] PACKAGE [PACKAGE ...]

Uninstall packages and remove them from the dependency.

Options:

  • -g, --global - Uninstall global packages. This would remove the venv from ~/vpip/pkg_venvs directly, so it actually doesn’t use the pip command.

update

vpip update [-g] [--latest] [PACKAGE [PACKAGE ...]]

Update packages and save to the dependency.

By default, this command only chooses a release from the compatible version range. For example: if the current version is 0.4.5, the compatible range is >=0.4.5,<0.5; if the current version is 1.8.7, the compatible range is >=1.8.7,<2.

If no package is specified, the command update all local packages in the dependencies.

Options:

  • -g, --global - Update global packages.

  • --latest - Update to the latest version instead of the compatible version.

list

vpip list [-g] [--outdated]

List packages in the dependencies. Only dependencies are listed so the result is different from vpip run pip list.

Options:

  • -g, --global - List globally installed packages.

  • --outdated - Check update from pypi.org and list only outdated packages.

outdated

vpip outdated [-g]

List outdated packages. This command is just a shortcut of vpip list --outdated.

run

vpip run ...

Execute shell command in the local venv. If the command has an option that is conflicted with the CLI, you can insert a -- to separate the actuall command. For example:

# this would disply the help message of pylint instead of vpip
vpip run -- pylint -h

update_venv

vpip update_venv [-g [PACKAGE ...]]

Update/rebuild the venv folder. It compares the Python version inside the venv with the Python outside of the venv. If they are incompatible then rebuild the folder. Otherwise, this command upgrades pip, wheel, etc, inside the venv. (See also PREINSTALLED_PACKAGES.)

Options:

  • -g, --global - Update global packages.

Extend commands

vpip allows you to define your own commands. In the setup.cfg file, add:

[vpip.commands]
# name = command
test = python setup.py test
build = make something

After adding these commands, you can invoke them with vpip test and vpip build. These commands would be run inside the venv. Extra arguments would be appended to the command.

Command fallback

Another way to extend vpip CLI is to define a command fallback. In the setup.cfg file, add:

[vpip]
command_fallback = python setup.py

This is a better solution if you are using a task runner (e.g. pyxcute) and don’t want to write down all commands in setup.cfg.
