I'm trying to emulate some behavior of the darkroom-mode Emacs mode -- specifically the margins setup.
I've figured out one piece of the puzzle -- specifically, to change window margins, I can eval
(set-window-margins nil <left margin> <right margin>).
Which is fine, but I'm noticing that the changes only occur in the current window, and will actually go back to the default margin if I switch to a different buffer using C-x left or right arrow key.
I'd like to figure out how to do the following:
- Set it so that all buffers get the same window-margin settings.
- Set it so that the margin settings persist after changing windows.
I know that it might involve using hooks, but I'm not exactly sure which hooks to use.
