I often write comments and code and look at modeline's Column# display
to verify I did not go beyond the 80th column when I type.
Are there any goodies in Emacs to help me accomplish this???
Maybe....
1. Emacs flashes the screen when I reach column 80
2. Emacs automatically adds a hard return and moves me to next line
when I reach column 80.
3. Emacs just doesn't let me type beyond column 80.

You could use `auto-fill-mode'[1] which automatically wraps text
once it reaches a certain column (specified by the variable
`fill-column'). Alternately, if you merely want a visual
indication of whether you've typed beyond a certain column, take
a look at vvb-mode <URL:
http://www.geocities.com/gchen275/xemacs/>. If you're using it
with Emacs (as opposed to XEmacs), you'll have to
(require 'lucid) first.

No that I know of.

Chris,
To get this when emacs loads, put the following in your .emacs:
(setq text-mode-hook 'turn-on-auto-fill)
As can be seen, that just sets it for text mode. Do another for, say,
html-helper-mode:
(setq html-helper-mode-hook 'turn-on-auto-fill)
Personally, I turnaround at 78:
(setq-default fill-column 78)
Since versions seem to be more than normally critical, mine's 20.7.1.
hth,
ken

Don't do that! (At least, don't advise others to do it.)
In general, a mode hook can contain many functions, and usually one
wants to add a function (or, more rarely, remove one). Therefore,
add-hook (and possibly remove-hook) is your friend.
(add-hook 'text-mode-hook 'turn-on-auto-fill)

Kai,
What you say makes sense now that I think about it. I can't remember
who it was who gave me the advice... I've been using it for years.
Haven't had a problem.

Yes, I didn't expect you would. It seems that text-mode-hook has no
other entries by default.
But there are other mode hooks which do have other entries by
default, so using setq to override the old value does bad things.
But it was only luck that it worked for text mode, so that's why I
issued the warning.

A really low-tech way is to narrow the frame to 80 characters. It
becomes really obvious when you go past the limit.

First, follow Kai's advice and use:
(add-hook 'text-mode-hook 'turn-on-auto-fill)
I haven't tested it yet, but I'm taking his word for it.
The .emacs file is read when emacs is started. You would need to
restart emacs-- i.e., close it and then open it up again-- for it to
take effect.
Note that you can set the fill-column number a couple other ways:
- e.g., if you want wrapping at column 45, do C-4 C-5 C-x f
- Put the cursor where you want wrapping to happen and do C-u C-x f

No, it would be just for text mode.

You could try line-limit-mode. See
