virtualenv-multipython 0.5.0

virtualenv discovery plugin for multipython and tox 4

virtualenv-multipython

virtualenv discovery plugin for multipython

This plugin is intended to be installed under multipython docker image. This is done automatically during multipython release, and there seems to be no reason to install this plugin manually by anyone.

Environment names supported are all multipython tags.

This plugin allows to use multipython tags in virtualenv:

$ virtualenv --python py314t /tmp/venv

Behaviour

• Loosely follow behaviour of builtin virtualenv discovery, with some important differences:
• Try requests one by one, starting with --try-first-with; if one matches multipython tag or is an absolute path, return it to virtualenv.
• If no version was requested at all, use sys.executable
• If no request matched conditions above, fail to discover interpreter.
• In particular, command names on PATH are not discovered.

Installation

$ pip install virtualenv-multipython

Configuration

Set multipython to be the default discovery method for virtualenv:

Option 1. Environment variable

VIRTUALENV_DISCOVERY=multipython

Option 2. Configuration file

[virtualenv]
discovery = multipython

Add these lines to one of virtualenv configuration files. Under e.g. Debian root, the file is /root/.config/virtualenv/virtualenv.ini
