Returns support for obtaining color values from the color scheme
Added possibility to select a template type ('default', 'color', etc)
Added possibility to use custom schemes by importing local files or remote repository
Removed unused files

Usage

import this flake in your 'flake.nix':

inputs.base16.url = 'github:alukardbf/base16-nix';

then, in any home-manager configuration:

home.user.${user} = { config, pkgs, lib }: {
  imports = [ base16.hmModule ];

}

{ pkgs, lib, config, ...}:
{
  config = {

    # Choose your theme
    themes.base16 = {
      enable = true;
      scheme = "solarized";
      variant = "solarized-dark";
      defaultTemplateType = "default";
      # Add extra variables for inclusion in custom templates
      extraParams = {
        fontName = "Roboto Mono";
        fontSize = "12";
      };
    };

    # 1. Use pre-provided templates
    ###############################

    programs.bash.initExtra = ''
      source ${config.lib.base16.templateFile { name = "shell"; };}
    '';
    programs.rofi = {
      enable = true;
      theme = "${config.lib.base16.templateFile { name = "rofi"; type = "color"; };}";
    };

    # 2. Template strings directly into other home-manager configuration
    ####################################################################

    services.dunst = {
        enable = true;
        settings = with config.lib.base16.theme;
            {
              global = {
                geometry         =  "600x1-800+-3";
                icon_path =
                  config.services.dunst.settings.global.icon_folders;
                alignment        = "right";
                font = "${fontName} ${fontSize}";
                frame_width      = 0;
                separator_height = 0;
                sort             = true;
              };
              urgency_low = {
                background = "#${base01-hex}";
                foreground = "#${base03-hex}";
              };
              urgency_normal = {
                background = "#${base01-hex}";
                foreground = "#${base05-hex}";
              };
              urgency_critical = {
                msg_urgency = "CRITICAL";
                background  = "#${base01-hex}";
                foreground  = "#${base08-hex}";
              };
        };
     };
  };
}

You can also use local schemes:

{ pkgs, lib, config, ...}:
{
  config = {
    # Choose your theme
    themes.base16 = {
      enable = true;
      customScheme = {
        enable = true;
        path = ./base16-custom-scheme.yaml;
      }
    };
  };
}

Or use an imported color scheme:

For example, import scheme repository into yours 'flake.nix'

inputs.base16-horizon-scheme = {
  url = github:michael-ball/base16-horizon-scheme;
  flake = false;
};

{ pkgs, lib, config, inputs, ...}:
{
  config = {
    # Choose your theme
    themes.base16 = {
      enable = true;
      customScheme = {
        enable = true;
        path = "${inputs.base16-horizon-scheme}/horizon-dark.yaml";
      }
    };

    # The template will be generated from the local scheme
    programs.rofi = {
      enable = true;
      theme = "${config.lib.base16.templateFile { name = "rofi"; };}";
    };
  };
}

Reloading

Changing themes involves switching the theme definition and typing home-manager switch. There is no attempt in general to force programs to reload, and not all are able to reload their configs, although I have found that reloading xmonad and occasionally restarting applications has been enough.

You are unlikely to achieve a complete switch without logging out and logging back in again.

Updating Sources

If you're using nix flakes:

Fork this repository
cd into repository dir
Enter nix develop and then run update-base16
Commit and push new files

If you're not using nix flakes:

cd into repository dir
Run update_sources.sh

Todo

Improve the source code.
