Ben Ford b51d8f632b Add custom theme support with wallpaper-based color extraction (#6)
* Add custom theme support with wallpaper-based color extraction

- Extended theme option to accept "custom" value
- Added customTheme configuration with wallpaperPath and variant options
- Integrated nix-colors colorSchemeFromPicture for dynamic color generation
- Updated wallpaper selection to handle custom paths
- Added VSCode theme fallback for custom color schemes
- Fixed nix-colors contrib function call (requires pkgs argument)
- Maintains full backward compatibility with existing themes

Users can now generate themes from their own wallpapers:
  omarchy = {
    theme = "custom";
    customTheme = {
      wallpaperPath = ./wallpapers/my-image.png;
      variant = "dark"; # or "light"
    };
  };

* Fix: Screen sharing broken due to Qt library version mismatch

  File changed: modules/nixos/hyprland.nix

  Problem:
  The omarchy-nix configuration was using xdg-desktop-portal-hyprland from the hyprland flake input, which had a Qt library version mismatch (6.9.1 vs 6.9.0). This caused the
   hyprland-share-picker to crash with "Cannot mix incompatible Qt library" errors, preventing screen sharing from working.

  Solution:
  Changed the portalPackage from the hyprland flake version to the stable nixpkgs version:

  - portalPackage = inputs.hyprland.packages.${pkgs.stdenv.hostPlatform.system}.xdg-desktop-portal-hyprland;
  + portalPackage = pkgs.xdg-desktop-portal-hyprland; # Use stable nixpkgs version to fix Qt version mismatch

  Why this works:
  - The stable nixpkgs version of xdg-desktop-portal-hyprland has consistent Qt library versions
  - This matches the working configuration used on other NixOS Hyprland setups
  - Maintains all screen sharing functionality while avoiding the Qt version conflict

# Omarchy Nix
Omarchy-nix (Omanix?) is an opinionated NixOS flake to help you get started as fast as possible with NixOS and Hyprland. It is primarily a reimplementation of [DHH's Omarchy](https://github.com/basecamp/omarchy) project - an opinionated Arch/Hyprland setup for modern web development.
This was mostly spun up in a weekend so if you have any issues please let me know, my goal is to eventually make this as seamless an install experience as Omarchy itself!
## Quick Start
To get started you'll first need to set up a fresh [NixOS](https://nixos.org/) install. Just download and create a bootable USB and you should be good to go.
Once ready, add this flake to your system configuration, you'll also need [home-manager](https://github.com/nix-community/home-manager) as well:
(You can find my personal nix setup [here](https://github.com/henrysipp/nix-setup) too if you need a reference.)
```nix
{
inputs = {
nixpkgs.url = "github:nixos/nixpkgs/nixos-25.05";
omarchy-nix = {
url = "github:henrysipp/omarchy-nix";
inputs.nixpkgs.follows = "nixpkgs";
inputs.home-manager.follows = "home-manager";
};
home-manager = {
url = "github:nix-community/home-manager";
inputs.nixpkgs.follows = "nixpkgs";
};
};
outputs = { nixpkgs, omarchy-nix, home-manager, ... }: {
nixosConfigurations.your-hostname = nixpkgs.lib.nixosSystem {
modules = [
omarchy-nix.nixosModules.default
home-manager.nixosModules.home-manager #Add this import
{
# Configure omarchy
omarchy = {
full_name = "Your Name";
email_address = "your.email@example.com";
theme = "tokyo-night";
};
home-manager = {
users.your-username = {
imports = [ omarchy-nix.homeManagerModules.default ]; # And this one
};
};
}
];
};
};
}
```
## Configuration Options
I've specified some basic configuration options to help you get started with initial setup, as well as some simple overrides for common configuration settings I found I was modifying often. These are likely subject to change with future versions as I iron things out.
Refer to [the root configuration](https://github.com/henrysipp/omarchy-nix/blob/main/config.nix) file for more information on what options are available.
### Themes
Omarchy-nix includes several predefined themes:
- `tokyo-night` (default)
- `kanagawa`
- `everforest`
- `catppuccin`
- `nord`
- `gruvbox`
- `gruvbox-light`
You can also generate a custom theme from any wallpaper image:
```nix
{
omarchy = {
theme = "custom";
customTheme = {
wallpaperPath = ./path/to/your/wallpaper.png;
variant = "dark"; # or "light" for light themes
};
};
}
```
This will automatically extract colors from your wallpaper and generate a matching color scheme for all Omarchy applications (terminal, editor, launcher, etc.).
