Given a location and day/night color themes, this file provides a
change-theme function that selects the appropriate theme based on
whether it is day or night. It will continue to change themes at
sunrise and sunset. To install:
Set the location:
(setq calendar-location-name "Dallas, TX")
(setq calendar-latitude 32.85)
(setq calendar-longitude -96.85)
Specify the day and night themes:
(require 'theme-changer)
(change-theme 'solarized-light 'solarized-dark)
You can also pass nil as either of parameters to change-theme, with the
effect of not using a theme (or using the default Emacs theme) during that
period of the day. For example:
(change-theme nil 'solarized-dark)
will result in setting the default Emacs theme during the day, and solarized-dark during the night.
Note: you may need to add the repository path to your loadpath. For example:
(add-to-list 'load-path "~/.emacs.d/elisp/theme-changer")
If you want to use the color-theme package instead of the Emacs 24 color theme facility:
(setq theme-changer-mode "color-theme")
(change-theme 'color-theme-solarized-light 'color-theme-solarized-dark)
