Empty $LANG causes test errors

[wouterweerkamp]

Issue Details

Tests that depend on the comparison of "Switching virtualenv: foobar [🐍Python 3.7.4]" fail when $LANG is not set (or when not supporting UTF-8).

Reason: in autoswitch_virtualenv.plugin.zsh we check for $LANG, and if it does not support UTF-* (or is not set), we remove the 🐍 from the DEFAULT_MESSAGE_FORMAT. In some of the tests however, we do not take this into consideration and simply assume 🐍 is always there, causing tests to fail.

Specifically, these tests fail:

• plugin - switches env when .venv found
• plugin - runs default env on load
• _maybeworkon - switches virtualenv if current virtualenv is different
• _maybeworkon - switches virtualenv if nothing is activated
• check_venv - works as intended with .venv available
• check_venv - activate if .venv unavailable but pipenv available
• check_venv - go to default if .venv unavailable
• check_venv - No security warning for readable only by owner permission
• check_venv - No security warning for readable by group permission
• check_venv - No security warning for readable by everyone permission

Solution: Remove 🐍 from the default message to avoid confusion. It is useless anyway.

Thanks for the issue report @wouterweerkamp. We can probably fix the $LANG variable correctly in the setup functions to solve this issue.

Would you like to give it a go?
