A declarative NixOS system and home configuration, focused on reproducibility and maintainability.

Overview

This repository contains my personal NixOS system configuration and home environment setup, managed through Nix flakes. It represents a transition from my previous Ansible-based setup (StanAngeloff/longitude) to a fully declarative system configuration.

Key Features

• GNOME Shell desktop environment with carefully chosen extensions
• Development Environment:
  • NeoVim with extensive plugin configuration via nixvim
  • Git with advanced configuration
  • Zsh as default shell
  • Podman for containerization
• Terminal Setup:
  • Alacritty as the primary terminal
  • tmux for session management
  • Custom prompt and key bindings
• Applications:
  • Brave Firefox with privacy-focused configuration
  • Thunderbird
  • Various GUI and CLI tools
  • Key programming languages
