kube_ps1 does not update within the same shell even when the context is changed

[kohpai]

Hi there!

I have been a very happy user of kube-ps1 for a few years now. Thank you for such a handy and useful tool!
But not long ago, I just noticed that changing the context does not update the generated prompt from kube_ps1;
only when I open a new shell or terminal does the prompt change.

I thought Oh My Zsh might have caused this, and spent some time debugging it.
But if omz was really causing this, then shouldn't running kube_ps1 directly show the correct prompt?

Does anyone have an idea what might have caused this?

Here's my config:

# ...
plugins=(git podman docker-compose kube-ps1)
# ...
export PROMPT=$PROMPT'$(kube_ps1)> '

I'm not exactly sure when this first happened, but at least it was working a month ago.

It seems to be caused by this PR; removing -L fixed it.

Wow! YOU ARE RIGHT! I tried that and it worked!

Is this a bug? Or is it because I run kube_ps1 in MacOS with Apple silicon?

It's not a bug, it's how Zsh zstat module works:

see man zshmodules

  -L     Perform an lstat (see lstat(2)) rather than a stat system call.  In this case, if the file is a link, information about the link itself rather than the target file is returned.  This option is required to make  the  link  element
                     useful.  It's important to note that this is the exact opposite from ls(1), etc.
