xPackageManager

A modern package manager for Arch Linux supporting pacman (via libalpm) and Flatpak backends.

Features

• Dual Backend Support: Manage both pacman packages and Flatpak applications from a single interface
• Modern Qt 6 UI: Built with QML and Qt Quick Controls 2 for a native desktop experience
• Rust Backend: Safe, fast, and concurrent package management operations
• System Maintenance: Orphan detection, cache cleanup, and database synchronization

Building

Prerequisites

• Rust (Edition 2024)
• Qt 6.2+ with QtQuick and QtQuickControls2
• libalpm (pacman library)
• flatpak development libraries
• CMake 3.24+ (optional, for CMake integration)

Arch Linux Dependencies

sudo pacman -S rust qt6-base qt6-declarative qt6-quickcontrols2 pacman flatpak

Build with Cargo

cargo build --release

Build with CMake (optional)

cmake -B build
cmake --build build

Running

# Development
cargo run --bin xpm-ui

# Release
./target/release/xpm-ui

Architecture

Core Types (xpm-core)

• Package: Package metadata (name, version, description, backend)
• Operation: Install/remove/update operations
• PackageSource: Trait for backend implementations

Pacman Backend (xpm-alpm)

• Read-only operations (search, list, info) work without privileges
• Write operations (install, remove, upgrade) require root via polkit

Flatpak Backend (xpm-flatpak)

• User-level installations work without root
• System-level installations require appropriate permissions

Service Layer (xpm-service)

• PackageManager: Orchestrates multiple backends
• Progress tracking for long-running operations
• Application state management

UI Layer (xpm-ui)

• CXX-Qt bridges expose Rust logic to QML
• QML views for different package management tasks
• Native Qt theming support

TODO

• Ability to downgrade pkgs.
• System update notifications.
• Dependency tree visualization.
