Figure 1: demo
I like to switch my emacs theme several times a day. I do this based on the time of day, brightness of the room I'm currently in, and my mood. So I made a little emacs package to make it more comfy to do so.
It provides 2 features:
- A convenient interface for switching between themes. Just
C-t. - 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 toC-c C-x C-v), then if the current theme is a dark theme, the image displayed will be./image-dark.pngand 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.pngwill 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.
(add-to-list 'load-path "~/path/to/theme-switcher/") ; (path) (with-eval-after-load 'org (require 'theme-switcher) (ts-init) (setq *theme-switcher-themes-light* '("ef-day" "leuven")) ; (light) (setq *theme-switcher-themes-dark* '("ef-elea-dark" "ef-cherie"))) ; (dark)
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.
If you'd like to change the default keybinding, you can specify your preferred keybinding in your setup.
(with-eval-after-load 'org (require 'theme-switcher) (ts-init "C-c t") ; (kbd) (setq *theme-switcher-themes-light* '("ef-day" "leuven")) (setq *theme-switcher-themes-dark* '("ef-elea-dark" "ef-cherie")))
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.
