📋 Changelog - Repository Improvements

Changes Made

This restructure makes the repository significantly more accessible to newcomers while maintaining a clean, modular architecture.

1. ✅ Comprehensive Documentation Structure

Created:

• docs/ARCHITECTURE.md - Detailed explanation of how the system is organized
• docs/QUICK_START.md - Step-by-step installation and setup guide
• docs/MODULE_GUIDE.md - In-depth documentation for each module
• CONTRIBUTING.md - Guidelines for contributing and customizing
• Module-level READMEs in:
  • modules/nixos/README.md
  • modules/home-manager/README.md
  • config/README.md

Updated:

• README.md - Added visual directory tree, quick links to docs, Makefile commands

2. ✅ Home Manager Restructure

Changes:

• Split monolithic apps.nix into focused modules:
  • cli-tools.nix - Command-line utilities (ripgrep, yazi, eza, zoxide, etc.)
  • gui-apps.nix - GUI applications (flatpak)
  • dev-tools.nix - Development tools and languages
• Created programs/ subdirectory for program-specific configs:
  • programs/gemini-cli.nix - Gemini AI CLI configuration
• Updated module imports in default.nix

Benefits:

• Easier to understand what packages do what
• Simpler to add/remove specific tool categories
• Better organization for future expansion

3. ✅ Fixed Structural Issues

Fixes:

• Removed duplicate import in hosts/nixos-btw/default.nix
• Deleted redundant hosts/nixos-btw/configuration.nix
• Fixed broken shell aliases (updated paths to match new structure)
• Corrected git configuration syntax (userName/userEmail → settings.user.name/email)

4. ✅ Added Helper Files

Created:

• Makefile - Common commands (switch, test, build, update, clean, check, fmt)
• .envrc.example - Template for direnv configuration
• CONTRIBUTING.md - Contribution guidelines

5. ✅ Inline Documentation

Enhanced all .nix files with:

• File-level comments explaining purpose
• Inline comments for complex configurations
• User-customizable sections clearly marked
• Examples and best practices

Files enhanced:

• flake.nix - Explained inputs, outputs, Home Manager integration
• All module files in modules/nixos/ and modules/home-manager/
• Host configuration files in hosts/nixos-btw/

Summary of Benefits

For New Users:

1. Clear entry point - README → Quick Start → Architecture → Modules
2. Visual structure - ASCII tree shows where everything lives
3. Step-by-step guidance - No guessing about what to customize
4. Safety - Instructions emphasize backups and testing
5. Troubleshooting - Common issues documented with solutions

For Experienced Users:

1. Modular architecture - Easy to understand and modify
2. Quick reference - Module guide shows all options at a glance
3. Helper tools - Makefile reduces typing
4. Contribution ready - Guidelines make it easy to share improvements

For Maintainability:

1. Self-documenting - Comments explain why, not just what
2. Consistent structure - Predictable organization
3. Focused modules - Single responsibility principle
4. Easy to extend - Templates for adding new modules

File Count

• Created: 13 new files
• Modified: 13 files
• Deleted: 2 files (redundant/backup)
• Total documentation: ~30 KB of new documentation

Testing

• ✅ Flake validation passed (nix flake check)
• ✅ No syntax errors
• ✅ All modules properly imported
• ✅ Git configuration corrected

Next Steps for Users

1. Read the docs (especially QUICK_START.md)
2. Customize personal info (username, git, hostname)
3. Test with make build before applying
4. Apply with make switch

Migration Notes

If you're updating from the old structure:

1. apps.nix split - Packages are now in:

   • CLI tools → cli-tools.nix
   • GUI apps → gui-apps.nix
   • Dev tools → dev-tools.nix
   • Gemini CLI → programs/gemini-cli.nix

2. Removed files:

   • hosts/nixos-btw/configuration.nix (merged into default.nix)

3. Updated aliases:

   • edit-config → edit-nixos (opens modules/nixos/)
   • edit-home-config → edit-home (opens modules/home-manager/)
   • New: edit-host (opens hosts/nixos-btw/)
