Double virtual env prompt when using pure prompt in Vscode

[ggydush]

Type: Bug

Behaviour

Expected vs. Actual

Expected: virtual environment information should only appear once.
Actual: virtual environment appears twice

I realize that it's difficult to support all custom shells, so let me know if you think this is outside of the scope.

Steps to reproduce:

1. Initialize pure prompt in zsh
2. Open a Vscode Python project and open terminal view

Note: the default PS1 of Pure is as follows:

%{%(12V.%F{$prompt_pure_colors[virtualenv]}%12v%f .)%(?.%F{$prompt_pure_colors[prompt:success]}.%F{$prompt_pure_colors[prompt:error]})${prompt_pure_state[prompt]}%f %}

It looks like Vscode modifies PS1 with

PS1=(pipeline-ErT9kUro-py3.11) ${env:PS1}

This causes the virtual environment to appear twice:

(pipeline-ErT9kUro-py3.11) pipeline-ErT9kUro-py3.11 > 

Diagnostic data

• Python version (& distribution if applicable, e.g. Anaconda): 3.11.5
• Type of virtual environment used (e.g. conda, venv, virtualenv, etc.): Poetry
• Value of the python.languageServer setting: Pylance

Output for Python in the Output panel (View→Output, change the drop-down the upper-right of the Output panel to Python)

Output

Is there a particular section that is useful? This dumps some sensitive information (e.g., ENV variables with keys) - I can redact that, it just appears multiple times

Here's the trace log.txt

Note: the default PS1 of Pure is as follows:

I expect "pure" prompt is set up in one of the initialization scripts for zsh (.zshrc etc.) which we currently don't have access to. This should be fixed by #22128.

For now, you can simply set VIRTUAL_ENV_DISABLE_PROMPT to 1 as a systems variable, which Python extension makes sure to pick up. That should disable the prompt in your case.

Great, thank you! Will follow #22128!
