$ show kiviktnm/decman
Decman is a declarative package and configuration manager for Arch Linux that ensures system state matches user-defined specifications. It uses a modular architecture with a core application and plugins for managing different subsystems (pacman, AUR, systemd, flatpak). Users define their desired system state in Python files, and Decman executes these specifications to install/remove packages, manage files and directories, enable/disable services, and apply other system configurations. The system tracks its state in a JSON store to determine what changes are needed between runs, and provides hook functions for custom logic at various points in the execution lifecycle.
The LLM identified 3 files worth highlighting for reuse:
Sophisticated command execution system with pseudo-terminal support, proper privilege dropping, environment handling, and comprehensive error management. This component could be extracted as a standalone library for running subprocesses in secure, controlled environments across various applications.
Well-designed plugin system using Python's entry point mechanism for discovery. Provides a clean interface for plugins to interact with the core system and modules, demonstrating a reusable pattern for building extensible applications with clear separation of concerns.
Simple but robust persistent key-value store with proper handling of complex data types like sets through custom JSON encoding/decoding. Features atomic writes via temporary files to prevent corruption and context manager support for safe usage, making it a generally useful component for applications needing persistent state.
