Well, we have a lot of dark themes, so in the interest of diversity I now support light themes.

;;; Commentary:
|
|
|
|
|
|
;; Because I couldn't get cycle-themes to work, I'm writing my own version.
|
|
;;
|
|
;; Terminology:
|
|
;; - colorscheme: determines the colors used by syntax highlighting and other
|
|
;; Emacs UI elements.
|
|
;; - theme: Structural representation of a "theme" that includes colorscheme
|
|
;; (see above), font, wallpaper. "theme" is a superset of "colorscheme".
|
|
;;
|
|
;; Wishlist:
|
|
;; - TODO: Find a way to update the terminal (e.g. terminator) theme.
|
|
;; - TODO: Ensure terminal font is updated when Emacs font changes.
|
|
;; - TODO: Support a light theme.
|
|
;; - TODO: Support Rick & Morty theme.
|
|
;; - TODO: Support retro/arcade/80s theme.
