venv prefix has no parentheses

[Phrogz]

Type: Bug

Behaviour

In a virtual environment the Terminal does not show parentheses around the .venv prefix.

Steps to reproduce:

1. Install WSL2 with Ubuntu 24.04 on Windows 11.
   • Unknown which of these versions is required to reproduce.
2. Open VS Code and use WSL extension to connect to Ubuntu.
3. In a new folder, issue Python: Create Environment… and select Venv and a Python 3.13 interpreter.
   • Unknown if 3.13 is required to reproduce.
4. Issue Python: Create Terminal

EXPECTED: Same PS1 prompt as seen when activating the venv in a WSL terminal: (.venv) gkistner@wsl:~/work/test$

ACTUAL: The prompt has the correct colors separating the pieces, but lacks parentheses or space: .venvgkistner@wsl:~/work/test$

[Phrogz]

Is this a regression caused by fixing #23193? Was #23080 trying to fix this for a specific Windows/WSL situation? I don't know, but I thought I should link to both of those.

[karthiknadig]

@Phrogz Try adding this setting to the WSL settings.json: "python.experiments.optOutFrom": ["pythonTerminalEnvVarActivation"], then reload. You may have to close and reopen terminals after reload.

@karthiknadig Adding "python.experiments.optOutFrom": ["pythonTerminalEnvVarActivation"] to my user settings JSON does indeed fix the problem. Thanks for the workaround. :)
