Aha - at last, a subject that if I write about it five or more years ago, the article is still relevant. Nothing to worry about here... :-)

You gotta love emacs, it never changes...

.emacs file

this is the “init file”

Setting variables in the init file -

setting modes in the init file. I like to use 80 char line breaks so,

      (add-hook 'text-mode-hook
        '(lambda () (auto-fill-mode 1)))

(add-hook 'text-mode-hook 'turn-on-auto-fill)

OK, each mode has a hook that is a variable holding a list of functions that are called when the hook activates. in this example when we start text-mode we shall execute the list of one function, a lambda that simply sets auto-fill-mode to 1

OK, what is the column after which I should break - well I set it at 75

(setq fill-column 75)
