Pacman & AUR Update Notifier

Sebenarnya banyak aplikasi system-tray notifier untuk Archlinux system updates seperti alunn, pacman-notifier, chase, dan lain-lain. Namun beberapa project sudah tidak aktif dan beberapa menggunakan library GTK+. Sedangkan untuk KDE sebenarnya ada aplikasi Chase yang dibuat oleh Chakra Project, namun saya sendiri kesulitan menggunakan Chase. Setelah googling akhirnya nemu blognya Andrea Scarpino (Archlinux KDE SC maintainer) yang menjelaskan bagaimana membuat system-tray notifier yang mudah dan simple.

Untuk membuat “Pacman & AUR Update KDE Notifier” sangat mudah dan hanya memerlukan shell script, KDialog serta AUR agent. Pada tulisan ini AUR agent yang digunakan adalah Cower. Jika pada mesin archlinux anda belum terinstall cower install terlebih dahulu via AUR.

if [[ ${pkgs} -gt 0 ]]; then
 msg1="${pkgs} in pacman"
fi

if [[ ${aurpkgs} -gt 0 ]]; then
 msg2=" ${aurpkgs} in AUR"
fi
let packages=${pkgs}+${aurpkgs}

if [[ ${packages} -gt 0 ]]; then
 kdialog --title "Out-of-Date packages" --passivepopup "There are ${packages} outofdated packages (${msg1}${msg2})" 10
