Emacs Theme Switcher

This package provides 2 features:

• a convenient interface for switching between themes.
• a way to provide dark mode versions of inline images in org mode.

For example, if, in an org file, I link to an image using [[./image.png]], I can provide another version of the image suitable for dark mode and write it to ./image-dark.png. Having done this, when I toggle inline images (usually bound to C-c C-x C-v), then if the current theme is a dark theme, the image displayed will be ./image-dark.png and not ./image.png (provided that said file exists). And if I then switch to a light theme, the inline images will be refreshed and ./image.png will be displayed.

Installation/Setup

Clone the repository in your preferred destination.

cd ~/path/to
git clone https://github.com/Duncan-Britt/theme-switcher.git

Add the following to your config, specifying the path to the cloned repository, as well as your preferred light and dark themes.

(use-package theme-switcher
  :load-path "~/path/to/theme-switcher/"
  :after org
  :config
  (setq *theme-switcher-themes-light* '("ef-day" "leuven"))
  (setq *theme-switcher-themes-dark* '("ef-elea-dark" "ef-cherie"))
  :bind
  ("C-t" . theme-switcher-choose-theme)
  (:map org-mode-map
        ("C-c C-x C-v" . ts-toggle-inline-images)))

To find your available themes, you can use ~M-x customize-themes~.

Usage/Keybindings

Switching Themes

Enter C-t to choose a theme in the mini buffer.

Light and dark mode images

To use this functionality, you first need to make your light and dark mode versions of your image and name them name.extension and name-dark.extension, respectively. For example, I could have files directed-graph.png and directed-graph-dark.png. They must be in the same directory.

Then, in org mode, link to the file like so: [[path/to/directed-graph.png]]. When you display inline images, if you are in dark mode, or switch to dark mode, directed-graph-dark.png will be displayed instead of directed-graph.png.
