Environment variables in the new status bar

[Walter Dörwald]

Hi all!

The new status bar in 3.3 is really great!

I was trying to have a status bar component that displays an environment variable (in my case Python's $VIRTUAL_ENV variable). After many tries I've managed to do that via user variables and an "Interpolated String" component.

I'm using zsh, so in my .zshrc I'm setting the user variable pyvenv from the environment variable like this:

precmd()
{
    iterm2_set_user_var pyvenv $(basename ${VIRTUAL_ENV:-none})
}

And then I'm defining an "Interpolated String" component with the string value:

🐍 \(user.pyvenv)

Which gives me the result I want.

Is this the best approach, or is there a more direct method?

Servus,

You're close. Since it seems like you're using shell integration, you should write a function called iterm2_print_user_vars to avoid clobbering precmd.

function iterm2_print_user_vars() {

    iterm2_set_user_var pyvenv $(basename ${VIRTUAL_ENV:-none})
}

If you're not using shell integration, then precmd is the right way to do it.

That worked, thanks!
