Is IPC really needed?

Maybe I'm missing something, and if I am please enlighten me, but couldn't the play-pause behavior be implemented with a simple script component with an if statement?

The play-pause icons that are being changed are of the button generated by Polybar. Sure you can write a script to echo out the correct icon but you would have to do a lot more to make that work as a button. Polybar provides handy click handlers (see more here). Hence, to change the button text, we need to use their inter process messaging API.

Feel free to ask more questions if you have.

So, I was thinking about something like this:

[module/playerctl-pp]
type = custom/script

tail = true

exec = dpolybar-player-status-pp

format = <label>
format-background = ${xrdb:color6}
format-foreground = ${xrdb:color0}

click-left = playerctl play-pause

# dpolybar-player-status-pp

set -euo pipefail

function status_to_icon {
  while read -r status; do
    if [ "$status" = "Stopped" ]; then
      echo <play-icon>
    elif [ "$status" = "Paused"  ]; then
      echo <play-icon>
    else
      echo <pause-icon>
    fi
  done
}

playerctl status --follow 2>/dev/null | status_to_icon

Do you see any significant differences? Btw, I'm using playerctl in a generic way, not specifically for Spotify; this assumes playerctld is running.

I see what you're trying to do. I'm also using this module along with playerctld running. The difference is clear that we're not using the IPC API but I don't see any point in switching to scripts unless there's really a need for it. Please let me know if there's more to your approach. Because for now, I'm just seeing it as another way to do it with no additional benefits.

[fuadsaud]

I'm still learning my ways around polybar, so this is mostly exploratory work that I'm doing.

One advantage I see in my approach is the fact that the bar name doesn't need to be replicated in the script, it's a simple one way relationship (bar calls script).

On the other hand, your IPC solution may perform better but I haven't tested that yet.
