Pacsea

Pacsea: A TUI for Arch Linux Package Management

Pacsea is a terminal user interface (TUI) for browsing, searching, and installing packages from Arch Linux repositories and the Arch User Repository (AUR). It is written in Rust and provides keyboard-first navigation.

Key Features

• Security Scanning for AUR Packages: Optional pre-installation security scanning using multiple tools (ClamAV, Trivy, Semgrep, ShellCheck, VirusTotal, custom patterns, aur-sleuth) with detailed scan summaries.
• Fuzzy Search: Toggleable fuzzy search mode for approximate package name matching.
• Unified Search: Search across official repositories and the AUR with results displayed in a single interface.
• Automated Package Update Checks: Background checks for available package updates with version comparison view.
• Keyboard-First Navigation: Interface designed for keyboard use with minimal keystrokes and Vim-like navigation patterns.
• Queue and Install: Queue packages for installation and execute installs with optional AUR security scans before installation.
• Persistent Lists: Recent searches and installation queues are saved and persist across sessions.
• Distro-Aware Updates: Automatically detects and uses appropriate mirror management tools for Manjaro, EndeavourOS, CachyOS, Artix, and standard Arch Linux.
• Integrated Process Execution: All operations execute within the TUI with real-time output streaming, progress indicators, and inline password prompts. No external terminal windows are required.
• News Feed: Unified feed combining Arch news, security advisories, package update notifications, and AUR package comments. Includes offline caching, filtering by source or date, search with history, bookmarking, and read/unread tracking.
• Preflight Review Modal: Review dependencies, files, and potential impacts before install/remove operations. For removals, shows reverse dependencies and affected services.
• PKGBUILD Preview: View and copy PKGBUILD files directly in the interface.
• AUR Comments Viewer: View community comments for AUR packages with markdown support and clickable URLs.
• Package Management: Manage installed packages including removal and downgrade functionality using the downgrade tool.

Security-First Approach

The security workflow provides optional scanning before installing AUR packages. This includes:

• ClamAV scans for malware detection.
• Trivy for filesystem vulnerability scanning.
• Semgrep for static analysis of PKGBUILDs.
• ShellCheck for linting PKGBUILD and .install scripts.
• VirusTotal hash lookups (requires API key configuration).
• Custom pattern checks for suspicious code patterns.
• aur-sleuth for LLM-based audit of packages.

User Interface

• Main App View: Interface displays package search results, package information, and installation queues in a single view.
• News Feed View: Browse Arch news, security advisories, package updates, and AUR comments with filtering and search capabilities.
• Preflight Review Modal: Review dependencies and potential impacts before proceeding with installations or removals.
• AUR Comments Viewer: Access community comments for AUR packages with markdown support and automatic updates when navigating between packages.
• TUI Optional Deps: Modal interface for installing and verifying recommended helper tools with environment-aware defaults.

Installation Notes

Pacsea can be installed through AUR helpers like paru or yay using the pacsea-bin (stable) or pacsea-git (latest) packages. It is also available via Cargo with cargo install pacsea. The application can be built from source using standard Rust tooling.

Conclusion

Pacsea provides a TUI for managing Arch Linux and AUR packages with integrated security scanning, news feed, and keyboard-first navigation. The application supports multiple Arch-based distributions.
