Installation

NixOS

Add tadaima to your flake inputs:

inputs.tadaima = {
  url = "github:Myxogastria0808/tadaima";
  inputs.nixpkgs.follows = "nixpkgs";
  inputs.ags.follows = "ags";
  inputs.astal.follows = "astal";
};

Use a pre-built example greeter

imports = [ inputs.tadaima.nixosModules.default ];

services.tadaima = {
  enable = true;
  package = inputs.tadaima.packages.${system}.movie;  # or .simple, .image
};

Package	Description
simple	Bare-minimum login form, no wallpaper, no styling
image	Static image wallpaper with Catppuccin Mocha theme
movie	Video/image wallpaper with GStreamer + Catppuccin Mocha theme

Build your own greeter

myGreeter = pkgs.stdenv.mkDerivation {
  name = "my-greeter";
  src = ./greeter;

  nativeBuildInputs = with pkgs; [
    wrapGAppsHook3
    gobject-introspection
    inputs.ags.packages.${system}.default
  ];

  buildInputs = [
    pkgs.glib
    pkgs.gjs
    inputs.astal.packages.${system}.io
    inputs.astal.packages.${system}.astal4
  ];

  preBuild = ''
    mkdir -p node_modules
    ln -s ${inputs.tadaima}/package/src node_modules/tadaima
  '';

  installPhase = ''
    mkdir -p $out/bin
    ags bundle app.tsx $out/bin/greeter
  '';
};

imports = [ inputs.tadaima.nixosModules.default ];
services.tadaima = {
  enable = true;
  package = myGreeter;
};

Nix (non-NixOS)

If you have Nix installed on another distro, you can build a greeter with nix build:

nix build github:Myxogastria0808/tadaima#movie

Configure greetd manually:

/etc/greetd/config.toml

[terminal]
vt = 1

[default_session]
command = "dbus-run-session cage -s -d -- /path/to/result/bin/greeter"
user = "greeter"

sudo mkdir -p /var/cache/tadaima
sudo chown greeter:greeter /var/cache/tadaima
sudo systemctl enable greetd

Arch-based distributions

1. Install dependencies:

   pacman -S greetd cage
   yay -S aylurs-gtk-shell

2. Build from an example:

   git clone https://github.com/Myxogastria0808/tadaima.git
   cd tadaima/examples/movie
   npm install
   ags bundle app.tsx ./my-greeter

   Or build your own greeter:

   mkdir my-greeter && cd my-greeter
   npm init -y
   npm install tadaima
   ags types --update --directory .
   ags bundle app.tsx ./my-greeter

3. Configure greetd:

   /etc/greetd/config.toml

   [terminal]
   vt = 1
   
   [default_session]
   command = "dbus-run-session cage -s -d -- /path/to/my-greeter"
   user = "greeter"

4. Create cache directory and enable greetd:

   sudo mkdir -p /var/cache/tadaima
   sudo chown greeter:greeter /var/cache/tadaima
   sudo systemctl enable greetd
