Installation

Nix With Home-Manager

If you manage your emacs configuration through home manager then you can enable darkplum with an overlay. For example if you are using home-manager:

{pkgs, ...}:
{
  programs.emacs = {
    enable = true;
    overrides = self: super: rec {
      darkplum-theme = self.melpaBuild rec {
        name = "darkplum-theme";
        pname = "darkplum-theme";
        version = "0.0.2";
        src = pkgs.fetchFromGitHub {
          owner = "rebeccaskinner";
          repo = "darkplum-theme";
          rev = "7a93038ede49c1c30e540d510d54ef83e00c2bce";
          sha256 = "0rsfvx8nsq9sbkdzs4mjqfwsqdwg5zz9y4wyqq05pamdhchmy2al";
        };
        recipe = pkgs.writeText "recipe" ''
          (darkplum-theme
          :repo "rebeccaskinner/darkplum-theme"
          :fetcher github)
        '';
        installPhase = ''
          runHook preInstall
          archive="$NIX_BUILD_TOP/source/$ename.el"
          if [ ! -f "$archive" ]; then
              echo "archive not found ($archive)"
              archive="$NIX_BUILD_TOP/packages/$ename-$version.tar"
          fi
          emacs --batch -Q \
              -l "$elpa2nix" \
              -f elpa2nix-install-package \
              "$archive" "$out/share/emacs/site-lisp/elpa"
          runHook postInstall
        '';
        meta = {
          description = "A dark purple theme for emacs";
          longDescription = "A dark purple theme for emacs";
        };
        license = pkgs.lib.licenses.gpl3Plus.spdxId;
      };
    };

    extraPackages = epkgs: with epkgs; [
    darkplum-theme
    # other packages go here
    ];
  };

  home.file.".emacs.d" = {
    source = ./emacs.d;
    recursive = true;
  };
}

If you wish to update darkplum to the latest version, you can get the most recent commit from github or from the repo by running git log. Update the rev field of the overlay to the commit you wish to use. You can calculate the sha256 field using nix-prefetch-url, for example:

nix-prefetch-url --unpack "https://github.com/rebeccaskinner/darkplum-theme/archive/<rev>.tar.gz"

Manual Installation

If you aren't using nix, you can install the theme manually. Clone this repo and copy darkplum-theme.el to your emacs configuration directory (generally ${HOME}/.emacs.d/).

Enabling The Darkplum Theme

If you are not using the emacs deamon you can enable the theme by adding the line below to your configuration file (${HOME}/.emacs.d/init.el):

(load-theme 'darkplum t)

Restart emacs and the theme should be loaded.

Enabling The Darkplum Theme With The Emacs Deamon

If you are using emacs clients with a single emacs deamon service, you might find that the theme does not load correctly when loaded the simple way. You can work around this by adding a frame hook to load the theme after creating a new frame attached to the deamon. Add the following to your emacs configuration file:

(defun configure-look-and-feel ()
  "Run some stuff after init, like setting a theme and disabling scrollbars."
  ;; Setup theme
  (load-theme 'darkplum t)
  )

(defun deamon-look-and-feel (frame)
  "Wrapper to run look-and-feel per FRAME with emacsclient."
  (select-frame frame)
  (configure-look-and-feel)
  )

(if (daemonp)
    (add-hook 'after-make-frame-functions #'deamon-look-and-feel)
    (configure-look-and-feel)
  )
