It is able to detect each battery installed and the system, and +calculate the remaining capacity of all batteries combined. Batteries added to +the system during runtime will also be detected. +.P +The daemon will send a warning notification the user when their battery level +drops below 20% while the batteries are discharging, and another critical +warning at 5%. +.P +The current battery level will also be displayed in stdout. +.SH USAGE +Call the lowbat executable in your xinitrc or xprofile. +.SH CUSTOMIZATION +There are no runtime flags or configuration files. Simply modify the source +code to suit your needs. +.SH COPYRIGHT +Copyright 2024 Tim Keller. +MIT License. +.P +.BR <https://TJKeller.xyz> +.SH SEE ALSO +.BR notify-send(1) +.P +.BR <https://www.kernel.org/doc/Documentation/ABI/testing/sysfs-class-power> @@ -64,11 +64,13 @@ void load_installed_batteries() { closedir(dir); } -void notifysend(char *title, char *content) { +void notifysend(char *title, char *content, NotifyUrgency urgency) { NotifyNotification *notif; notify_init("lowbat"); notif = notify_notification_new(title, content, NULL); + notify_notification_set_timeout(notif, NOTIFY_EXPIRES_NEVER); + notify_notification_set_urgency(notif, urgency); notify_notification_show(notif, NULL); } @@ -133,12 +135,12 @@ int main() { if (discharging) { if (capacity <= 5 && !w_lowbat_crit) { sprintf(msg, "%d%% remains", capacity); // TODO snprintf me plz - notifysend("Critical Low Battery Warning", msg); + notifysend("Critical Low Battery Warning", msg, NOTIFY_URGENCY_CRITICAL); w_lowbat_crit = w_lowbat = 1; } else if (capacity <= 20 && !w_lowbat) { sprintf(msg, "%d%% remains", capacity); - notifysend("Low Battery Warning", msg); + notifysend("Low Battery Warning", msg, NOTIFY_URGENCY_NORMAL); w_lowbat = 1; } @@ -13,9 +13,9 @@ while true; do if is_discharging; then if [ $capacity -le 5 ] && [ $warning_level -lt 2 ]; then - notify_send "Critical Low Battery Warning" "${capacity}% remains" + notify-send -u critical -w "Critical Low Battery Warning" "${capacity}% remains" elif [ $capacity -le 20 ] && [ $warning_level -lt 1 ]; then - notify_send "Low Battery Warning" "${capacity}% remains" + notify-send -u normal -w "Low Battery Warning" "${capacity}% remains" fi else warning_level=0 |
