Add setting to disable prepending venv prompt to PS1

[Riezebos]

I am using Starship (https://starship.rs/) as prompt. When I run source .venv/bin/activate in a regular terminal, my prompt becomes:

but when vscode-python activates the env, the prompt becomes:

This is probably caused by this being part of the environment changes done by this extension: PS1=(.venv) ${env:PS1}

I could disable the "python.terminal.activateEnvironment" setting and activate the environment some other way, but I like it that this extension does that and would like to keep it that way.

Could an option be added to disable the PS1 change?

Hello @Riezebos Thanks for filing the issue here.

Are you able to add:

 "python.experiments.optOutFrom": ["pythonTerminalEnvVarActivation"],

in your settings.json and see if you can repro the same problem?

Thanks, that worked!

Thanks. I was having the same problem with the prompt being corrupted when the terminal was opened with the virtual environment. Using the "python.experiments.optOutFrom": ["pythonTerminalEnvVarActivation"] with the pre-release version of the extension fixed the issue. Cheers ...

Hi folks, we are trying to fix the root cause of this problem step by step: starting from: #23159 PR solely wont fix the problem but upcoming PR after #23159 is resolved will address PS1) There may have to be additional PR in addition to #23159 to specifically address PS1 issue. so you can enjoy all the benefits from the terminal env var activation experiment without getting incorrect PS1.
Opt out of the experiment for now, but I would be interested to have folks try the experiment when I merge changes for #23159
