Do you want Emacs to follow your MacOS/Linux/Windows Dark-mode on/off options?

This is it. This program lets Emacs change between 2 user defined (customizable) themes to be automatically changed when Dark Mode set on/off on MacOS/Linux/Windows. For now it supports Linux through Gnome and Termux(Android).

By default, themes are wombat and leuven, since these are bundled with Emacs.

Install it from MELPA and add to your .emacs file:

(require 'auto-dark)
(auto-dark-mode t)

Or simply copy the auto-dark.el file to ~/.emacs.d/auto-dark/auto-dark.el (or clone this repository there), and then add the following to your .emacs:

(add-to-list 'load-path "~/.emacs.d/auto-dark/")
(require 'auto-dark)
(auto-dark-mode t)

Or use use-package to install:

(use-package auto-dark
  :config (auto-dark-mode t))

If you use Spacemacs, add (auto-dark) to the dotspacemacs-additional-packages list and add the following to dotspacemacs/user-config:

(use-package auto-dark
  :init (spacemacs/defer-until-after-user-config (lambda () (auto-dark-mode t)))
  :defer t)

This ensures that auto-dark-mode is activated only after spacemacs's built-in theme loading logic.

If you use Doom Emacs, the following config should do the trick

;; In your packages.el
(package! auto-dark)

;; In your config.el

(after! doom-themes
  ;; set  your favorite themes
  (setq! auto-dark-dark-theme 'doom-one
        auto-dark-light-theme 'doom-one-light)
  (auto-dark-mode 1))

Change your dark-mode settings on MacOS/Linux/Windows and let the magic happens :D

The light/dark themes can be customized using the Emacs customization system. M-x customize-group auto-dark.

You can also take advantage of the hooks auto-dark-dark-mode-hook and auto-dark-light-mode-hook to make it even further customizable. Take a look at this article on how to Integrate Catppuccin with Auto-Dark.

For terminal-based emacs, it is possible to check dark mode status using osascript rather than relying on the built-in Applescript support that GUI Emacs provides. To enable it, customize dark-mode-allow-osascript and set it to t.
