Vi-like end of buffer in emacs?

Vi-like end of buffer in emacs?

[wlcna]

Is there a way to get emacs to show something like the squiggles that vi 
shows under the last line of text in the file?  The ideal behavior is Vim 
under GUI, which shows that but also *just slightly* changes the background 
color with the squiggles.   This is not a huge deal but I find it comforting 
to know exact information about the file, including how many line 
terminations I have in there, and this is an instantaneous way of telling 
that.

I don't really use vi to know what you are looking for. However, there
are ways to configure and show buffer endings and empty lines and
such. If you search this newsgroup's recent history, you can find the
information. You can also browse the customizations with M-x
customize. There are a lot of them to list here. I don't know of
anything comparable in vi, so you are on your own there.

You want fringe-mode. M-x customize-group RET fringe RET.

It doesn't show actual characters in the buffer like vi does, but has  
a graphic on the edge.

Thanks!  I figured someone probably had an easy fix for this.  I tried it 
out a bit.  Not as nice as vim, but it's OK.  Not sure why it shows the 
little marks on the last line of the file when you can type on that line, 
but it's OK.

I noticed though that I have to have this customize group thing instead of 
more straightforwardly using lisp to set this in my init file code... 
(fringe-mode) can be put in my init file, but the only argument is the size 
of the fringe and no args for fact that I want to show empty lines.

But anyway, customize works, though I avoid that customize stuff, just 
coming back to emacs now - it irks me and seems opposed to the idea of all 
the lisp integration...

But thanks very much, it works.

Anything you set via customize can be done with elisp. Open fringe.el  
and look for (defcustom). Alternately, you can pull the definitions  
out of the (custom-set-variables) block and make them regular (setq)  
calls.

Nothing wrong with customize, in my opinion.

All you need is: (setq-default indicate-empty-lines t)

For my customization, I prefer the Emacs 21 empty line glyphs:

(when (fboundp 'define-fringe-bitmap)
   (define-fringe-bitmap 'empty-line [0 0 #x3c #x3c #x3c #x3c 0 0]) ; 
Emacs 21
   )

And less obtrusive color:

(when (display-color-p)
   (let ((bg-mode (frame-parameter (selected-frame) 'background-mode)))
     (cond ((eq bg-mode 'light)
	   (set-face-foreground 'fringe "grey60"))
	  ((eq bg-mode 'dark)
	   (set-face-foreground 'fringe "grey40")))))

NICER THAN WHAT I HAD!  THANKS! It's in my init file.

Looks better, I put that in there too.  Nicer.  I just wish now it didn't 
show one two many lines of these marks, and as mentioned, still doesn't have 
the vim bg color slight adjustment (in gui vim) either, but hey, it's 
getting there!  Thanks!
