virtualenv

The plugin displays information of the created virtual container and allows background theming.

To use it, add virtualenv to the plugins array of your zshrc file:

plugins=(... virtualenv)

The plugin creates a virtualenv_prompt_info function that you can use in your theme, which displays the basename of the current $VIRTUAL_ENV. It uses two variables to control how that is shown:

ZSH_THEME_VIRTUALENV_PREFIX: sets the prefix of the VIRTUAL_ENV. Defaults to [.
ZSH_THEME_VIRTUALENV_SUFFIX: sets the suffix of the VIRTUAL_ENV. Defaults to ].
