I know there are solutions to making emacs show the 80 line column, but I don\'t want that sort of visual disturbance. I\'d just like to make it highlight a line if it\'s ov
Try highlight-80+.el. You can acquire it from here.
highlight-80+.el
To install it, just add the following to your .emacs:
.emacs
(add-to-list 'load-path "/path/to/highlight-80+") (require 'highlight-80+)
You can then enable it via:
M-x highlight-80+-mode
highlight-80+-mode
