linebreak after 78characters

linebreak after 78characters

Hello emacsians!

I just wondered where I can set permanently the option, that emacs breaks eac 
line after 78characters. I can`t find it on the menu.

greetings,

bienchen

(set-fill-column 78) in .emacs. This value can be set in every buffer 
to a different value (buffer-local).

Hm, this doesn`t work for me :-(
Normally I get the line break with a whitespace after the last word, hanging 
over the 78-chars mark.

I think you have to turn on auto-fill-mode also...

If you want auto-fill-mode to be on when in a particular mode you
need to add this to the mode's hook.

(add-hook 'foo-mode-hook  'auto-fill-mode)

If you want it on for every buffer regardless of mode you could try
putting it on the after-change-major-mode-hook but that won't cover
fundamental mode.

Personally I use (global-set-key [f12] 'auto-fill-mode) so I can
toggle it on and off with a single key no matter what mode I'm in.

I donot know how it is done, but in auctex (latex) mode the following
lines at the end of a file set the column width to 90 columns.

%%% Local Variables
%%% mode: latex
%%% fill-column: 90
%%% End:

That would be permanent only for the file you've put that in.

It seems different people have different views on what the OP is
asking.
1) turning auto-fill-mode on
2) setting the column at which wrapping occurs

To set the fill-column globally (for all files that don't have
Local Variables (described above) or a mode-hook etc. use
M-x customize-option <ret> fill-column <ret>
