DannyDannyDanny 072f197660 feat: unify theme switching with cross-platform script

- Create unified theme.sh script that works on both WSL and macOS
- Update fish alias to use new unified script instead of WSL-specific one
- Maintain backward compatibility with existing theme command
- Update documentation to reflect unified approach
- Script automatically detects platform and calls appropriate functionality

Unified Theme Switching

Unified theme switching that works across platforms (WSL and macOS) for Neovim, Alacritty, and Windows Terminal.

This solution uses a single theme command that detects the platform and switches themes appropriately.

How It Works

The theme command detects the platform (WSL vs macOS)
On WSL: Updates Neovim, Windows Terminal, and Windows system theme
On macOS: Updates Neovim and Alacritty themes via Nix configuration
Uses the same nvim_color_scheme file for Neovim on both platforms

Setup

The configuration is already set up! The theme command is available as a fish alias.

To switch themes, use the unified command:

theme light   # Switch to light theme
theme dark    # Switch to dark theme

Usage

Unified Theme Command

# Switch to light theme (works on WSL and macOS)
theme light

# Switch to dark theme (works on WSL and macOS)
theme dark

What Gets Updated

On WSL:

Neovim theme (via ~/.local/share/nvim_color_scheme)
Windows Terminal settings
Windows system theme
Windows sound scheme

On macOS:

Neovim theme (via ~/.local/share/nvim_color_scheme)
Alacritty theme (via Nix configuration)

Manual Configuration (macOS only)

You can also manually edit nixos/home/danny/home.nix and change:

isLightTheme = true;   # for light theme
isLightTheme = false;  # for dark theme

Then run: cd nixos && sudo darwin-rebuild switch --flake .#Daniel-Macbook-Air

Files

scripts/theme.sh - Main unified theme switching script
scripts/switch-alacritty-theme.sh - Alacritty-specific theme switching (used by theme.sh)
scripts/detect-system-theme.sh - Detects current macOS system theme (for reference)
nixos/fish.nix - Contains the theme fish alias
nixos/home/danny/home.nix - Contains the conditional Alacritty configuration
bashscripts/wsl_theme.sh - Legacy WSL script (replaced by theme.sh)

Theme Colors

Catppuccin Latte (Light)

Background: #eff1f5 (base)
Foreground: #4c4f69 (text)
Accent colors optimized for light backgrounds

Catppuccin Mocha (Dark)

Background: #1e1e2e (base)
Foreground: #cdd6f4 (text)
Accent colors optimized for dark backgrounds

Integration with NixOS

The solution uses Nix's conditional configuration in home.nix:

colors = let
  isLightTheme = true;  # Change this to switch themes
  
  lightColors = { /* Catppuccin Latte colors */ };
  darkColors = { /* Catppuccin Mocha colors */ };
in if isLightTheme then lightColors else darkColors;

This approach:

✅ Works with Spotlight/Applications folder launches
✅ No complex file reading or external dependencies
✅ Integrates cleanly with NixOS configuration
✅ Simple and reliable - just change a boolean and rebuild
✅ Easy to understand and maintain
