Demos

What is this ?

Day-night-plasma-wallpapers lets you configure the wallpapers you want for the day and those you want when working at night.

Requirements

A plasma 5 desktop environment
qdbus (in qttools package)
home-manager here

Configuration

Create the directories Night and Light in ~/.local/share/wallpapers
Put your day wallpaper in ~/.local/share/wallapers/Light
Put you night wallpaper in ~/.local/share/wallpapers/Night

Installing (Nix or NixOS only) with home-manager

It is recommanded to use the home-manager setup as it's the easiest.

The first thing to add to your home.nix file is to import the the nur-no-packages repo :

let
  home-manager = builtins.fetchGit {
    url = "https://github.com/rycee/home-manager.git";
    rev = "dd94a849df69fe62fe2cb23a74c2b9330f1189ed"; # CHANGEME 
    ref = "release-18.09";
  };
  nur-no-pkgs = import (builtins.fetchTarball {
    url = "https://github.com/nix-community/NUR/archive/master.tar.gz";
    sha256 = "18wa9n11p8wa9zh07p04rk90arld8155mzbcrx3bwfl42fcvha4m" ;
  }) {};
in
{
}

Next you need to add the day-night-plasma-wallpapers module : this is what links the package's service file and autostart script to your home directory.

  imports = [
    nur-no-pkgs.repos.shamilton.modules.home-manager.day-night-plasma-wallpapers 
  ];

Now you need to install the day-night-plasma-wallpapers package.

  # This is needed to install nur packages see https://github.com/nix-community/nur#installation
  nixpkgs.config.packageOverrides = pkgs: {
    nur = import (builtins.fetchTarball "https://github.com/nix-community/NUR/archive/master.tar.gz") {
      inherit pkgs;
    };
  };
	
  # Here we install the day-night-plasma-wallpapers package
  # (or derivation should I say), from my repository
  home.packages = [
    nur.repos.shamilton.day-night-plasma-wallpapers 
  ];

Lastly you can enable the service with :

services.day-night-plasma-wallpapers.enable = true;

Here is an overview of what a minimal home.nix file looks like :

{ pkgs ? import <nixpkgs>{}
, ... }:

with builtins;
with lib;
with pkgs;

let
  home-manager = builtins.fetchGit {
    url = "https://github.com/rycee/home-manager.git";
    rev = "dd94a849df69fe62fe2cb23a74c2b9330f1189ed"; # CHANGEME 
    ref = "release-18.09";
  };
  nur-no-pkgs = import (builtins.fetchTarball {
    url = "https://github.com/nix-community/NUR/archive/master.tar.gz";
    sha256 = "18wa9n11p8wa9zh07p04rk90arld8155mzbcrx3bwfl42fcvha4m" ;
  }) {};
in
{
  imports = [
    nur-no-pkgs.repos.shamilton.modules.home-manager.day-night-plasma-wallpapers 
  ];
  
  nixpkgs.config.packageOverrides = pkgs: {
    nur = import (builtins.fetchTarball "https://github.com/nix-community/NUR/archive/master.tar.gz") {
      inherit pkgs;
    };
  };

  home.packages = [
    nur.repos.shamilton.day-night-plasma-wallpapers 
  ];

  services.day-night-plasma-wallpapers.enable = true;
}

Last thing to do is to tell systemd to start the timer. (Which cannot be automated in the module, if you know how, please tell me). $ systemctl --user start day-night-plasma-wallpaper.timer

TODO

Make a configuration system
Make a GUI for the configuration
Package for other distros
Convert the script to native code
Find another solution than sleeping for 10 seconds before running the script : This sleep is the only solution found to be able to use qdbus after session boot with ~/.config/autostart-script script
Manage multiple wallpapers

Recommandations

This package works well with the macMojave desert Wallpapers :
