Python Virtual Environment - Prompt Prepended with virtual env name

[jiaulislam]

Hi. Thanks guys your works are awesome.

Could anyone please help with below marked text to disable I just want the Theme Virtual env Prompt nothing else.

Terminal: Windows Terminal
Powershell version: 7.1.1
Font: Meslo S

Did you follow the install guide to set the prompt in your powershell profile? What does it look like?

[jiaulislam]

@lnu thanks for your reply.
I did followed the instructions from installation guide. But I was unable to fix that. As I'm not that pro with programming knowledge. However just the Time Date is showing but the Environ Variable is still there.

@jiaulislam that's controlled by what's in the activate script. If you look at its content, there should be a switch to disable prepending the prompt (they hijack the current prompt). Depending on the type of virtual env you either need export PYENV_VIRTUALENV_DISABLE_PROMPT=1, VIRTUAL_ENV_DISABLE_PROMPT=1 or something different. Best to look at what's in the script on your end ;-)

It works now. Thanks for your time ❤️

If VIRTUAL_ENV_DISABLE_PROMPT=1 is set, it seems like there is no way to know whether the shell is in an activated environment.

It turns out the default theme jandedobbeleer disabled fetch_virtual_env, so the prompt is not showing python venv.
Other themes like agnoster show the venv correctly, works fine with VIRTUAL_ENV_DISABLE_PROMPT=1

EDIT: I didn't read well the reply for @JanDeDobbeleer. I was trying to put the env. variable VIRTUAL_ENV_DISABLE_PROMPT in the PW profile but I had to place it in the activate ps1 file of the venv folder. But I managed to make this universal for any new virtualenv created and not only the virtualenv of an actual project. Just have to put VIRTUAL_ENV_DISABLE_PROMPT in C:\Users\<user>\AppData\Local\Programs\Python\Python39\Lib\venv\scripts\common\Activate.ps1, after $env:VIRTUAL_ENV = $VenvDir, like this:

...
# Now set the environment variable VIRTUAL_ENV, used by many tools to determine
# that there is an activated venv.
$env:VIRTUAL_ENV = $VenvDir
$env:VIRTUAL_ENV_DISABLE_PROMPT = 1

if (-not $Env:VIRTUAL_ENV_DISABLE_PROMPT) {
...

I Hope it helps for anyone!

Hi! Where do I have to put VIRTUAL_ENV_DISABLE_PROMPT=1? I putted in my ps1 profile file after the theme import but it didn't work. Like this:

$env:VIRTUAL_ENV_DISABLE_PROMPT=1

@JanDeDobbeleer @jiaulislam

Thanks in advance :D

I was able to get $env:VIRTUAL_ENV_DISABLE_PROMPT = 1 when placing it in the default PowerShell profile.ps1. However, here are two things of note:

1. You have to restart the shell to refresh the profile (or manually refresh it) if you want the updated environment variables.
2. If you set the environment variable manually while in an active virtual environment, you have to deactivate/reactivate it.

Hello, awesome work,
I am using larserikfinholt.omp.json theme, I would like to add virtualenv
but don't know where to put this code from the doc.
{
"type": "python",
"style": "powerline",
"powerline_symbol": "",
"foreground": "#100e23",
"background": "#906cff",
"template": "  {{ .Full }} "
}

Thank you

@wereket78 depending on how you're currently using oh-my-posh, you might need to first export your config. The customize section in the docs has all that information.

I added a section after exporting the config, I modified the colors to match doom-moonlight, but the python env does not show after adding the section

[JanDeDobbeleer]

You're missing the property to tell it to fetch the virtual env and the .Venv property in the template. Read the python documentation.

Hello
I added property
https://github.com/wereket78/dotfiles/blob/main/executable_dot_mytheme.omp.json#L39
It does not show the venv
thank you
