Have a look at the approach taken by the logos.el
package. There's a section in the manual called Leverage logos-focus-mode-hook.
The idea there is that when you enable the logos-focus-mode
, you'll often want to change some other minor modes and variables too. But when you disable logos-focus-mode
, you'll want those other minor modes to revert to their previous value. The Logos package provides a few convenience functions to remember the previous values, and they are automatically restored when logos-focus-mode
is turned off.
Perhaps the code for that could be made generic, instead of being coupled to the logos-focus-mode
?
