Portage Backend for KDE Discover

A native Portage package manager backend for KDE Discover on Gentoo Linux systems.

Overview

This project provides full Portage integration into KDE Discover, allowing Gentoo users to manage their system packages through the familiar Discover graphical interface instead of command-line tools like emerge.

Features

Implemented

• Package Browsing: View all available packages from Gentoo repositories
• Installed Packages: Display all currently installed packages with version information
• Package Search: Search packages by name or category
• Category Navigation: Browse packages organized by Portage categories (net-im, dev-util, etc.)

Note: This is community-maintained software. Package install, removal, and updates use emerge via KAuth (polkit). Test on non-production systems first; long emerge runs and edge cases (masking, licenses, slot conflicts) may still need manual intervention.
