Polybar

Mechanism

Polybar runs as a daemon. It usually has a config file (config.ini) which can include other files. It supports an IPC mechanism (polybar-msg) to restart or reload the bar.

2. Themis’s Approach

We use Template + Include + Command.

1. Generate ~/.config/polybar/colors.ini.
2. Include it in config.ini: include-file = ~/.config/polybar/colors.ini.
3. Send a restart command.

3. User Setup

One-time: Add include to ~/.config/polybar/config.ini:

[global/wm]
include-file = ~/.config/polybar/colors.ini

4. Equivalent Configuration

enroll:
  polybar:
    type: template
    input: "~/.config/themis/templates/polybar_colors.ini.j2"
    output: "~/.config/polybar/colors.ini"
    # Command to reload/restart
    reload_cmd: "polybar-msg cmd restart"
