polybar VS dotfiles

I'd like to just be able to write a short shell script to check if an exit node is in use, and then pipe that output into polybar which I use anyway. The problem is that I can't find an option in the tailscale Linux CLI client that will show me whether I'm using an exit node or not. Is there a way to do this?

And I follow the step here. https://github.com/polybar/polybar/issues/763

I am on Arch Linux and I am using pywal to generate a colour palette from my wallpaper, which I then use throughout my system. In particular, i have a bash script which grabs these colours and uses them for polybar. The problem is that sometimes these colours do not have enough contrast, and the bar is hard to read. Is there any tool that would allow me to check the readability of my colours, and modify them accordingly, directly from my script? If not, how should I be approaching this issue?

Hello, currently I am trying to get polybar setup on XFCE. I was getting an error along the lines of "background_manager: Failed to copy slice of root pixmap" and according to this GitHub issue, the only solution is to try and set the background another way, like using feh. My only issue now is that it seems like feh isn't actually doing anything whenever I use it to set a wallpaper. I believe this could be because of a conflicting system in XFCE that sets the wallpaper, how can I disable XFCE wallpapers?

Refer to the "Formatting" section of the polybar wiki" (e.g. things like -padding, -margin, -spacing).

As per the docs https://github.com/polybar/polybar/wiki/Configuration it uses a ARGB convention

The short answer is you can't.

There are a few different solutions here, try them out : https://github.com/polybar/polybar/issues/433
