About

SUN (Slackware Update Notifier) is a tray notification applet and background daemon that monitors the Slackware ChangeLog.txt for package updates and notifies the desktop user when new updates are available. It also serves as a CLI tool for checking updates and viewing OS and machine information.

SUN works by default with slackpkg, as well as with other tools like slpkg. You can probably use SUN with other Slackware-based Linux distributions as well.

Features

Desktop notification when new updates are detected
System tray icon with numeric badge showing the update count
Badge syncs immediately with daemon notification via SIGUSR1
Greyscale tray icon when the daemon is not running
Colored ChangeLog dialog with date headers and comment highlighting
Config dialog in tray menu to view the active sun.conf settings
sun check CLI command to check for updates without the daemon
sun config CLI command to view the active sun.conf settings
sun info CLI command to view hardware and OS information
sun changelog CLI command to view the remote ChangeLog.txt
sun log CLI command to view the daemon log
sun start / stop / restart / status CLI commands to manage the daemon
NOTIFICATIONS option to enable/disable desktop notifications independently of the tray badge
HTTP_TIMEOUT option to configure the remote fetch timeout
Mirror version warning when HTTP_MIRROR does not match installed Slackware version

Yellow tray badge when packages are pending upgrade; auto-refreshes when data.json, PACKAGES.TXT, or /var/log/packages changes
Package manager auto-detected from LOG_PATH (slpkg or slackpkg); no extra configuration required
