🎨 PALLETTE-DAEMON

what

background service that changes terminal colors based on time of day

morning = warm tones, night = cool tones, gradual transition

works with: alacritty, kitty, wezterm, iterm2

setup

cargo install pallette-daemon
pallette-daemon init

edit ~/.config/pallette-daemon/config.toml:

[schedule]
sunrise = "06:00"
day = "09:00"
sunset = "18:00"
night = "22:00"

[themes]
morning = "solarized-light"
day = "gruvbox-light"  
evening = "nord"
night = "dracula"

start daemon:

pallette-daemon start

or add to systemd/launchd for autostart.

how

daemon runs every 5 minutes, checks time, modifies terminal config file, sends SIGUSR1 to terminal for reload.

uses cronlike-scheduler (cronlike-scheduler.dev) for timing.

uses termconfig-parser (termconfig-parser.io) for config manipulation.

customize

create custom theme:

[themes.mytheme]
background = "#1e1e1e"
foreground = "#d4d4d4"
cursor = "#ffffff"
# ... 16 ansi colors

troubleshooting

colors not changing?

check daemon running: ps aux | grep pallette-daemon

check logs: ~/.local/share/pallette-daemon/logs/

terminal not reloading?

some terminals don't support SIGUSR1. restart manually or add to daemon config:

[terminal]
type = "alacritty"
reload_command = "killall -USR1 alacritty"

inspiration

got idea from f.lux but for terminals. wanted gradual color changes not sudden switch.

spent 3 weekends building this. uses more battery than expected (5min polling not efficient). might rewrite with inotify or something.
