how to turn on showing end of file?

how to turn on showing end of file?

[jidanni]

I recall I was able to have some indication
of the end of file, e.g., tildes below.
However nowadays it seems it is gone.

Modern Emacsen use the fringes for this purpose.

Yes, but they are gone for me, as are the tildes in
$ emacs -nw /etc/motd

Yes I can see the fringe-mode marker when a line wraps, or the \ when using
-nw, but I can no longer see any of the tilde stuff for after the end of file.

Any chance you are confusing emacs with vim, which has this `tilde
stuff' ?

OK, I need to put
(setq indicate-buffer-boundaries t
      indicate-empty-lines       t)
into some hook that gets called for every buffer, here in emacs-version "23.1.50.1".

Re: how to turn on showing end of file?

[jidanni]

Indeed, I had
(setq indicate-empty-lines t)
but here in emacs-version "23.1.50.1" it is no longer inherited into
every buffer. One needs to put it into some hook.

Re: how to turn on showing end of file?

[jidanni]

OK: (setq-default indicate-empty-lines t) solved.

Re: how to turn on showing end of file?

[jidanni]

OK, here is how I was vicitmized.

I used to use
(setq default-indicate-empty-lines t)

A few days ago I got the message
Compiling file /home/jidanni/.emacs ...
.emacs:436:7:Warning: `default-indicate-empty-lines' is an obsolete variable
    (as of Emacs 23.2); use `indicate-empty-lines' instead.

(I wonder how what people who don't compile their .emacs file will get
that news.)

So I changed it to
(setq indicate-empty-lines t)

Then after a few days I started wondering where the indicators went.

So one needs to change it to
(setq-default indicate-empty-lines t)

Sorry, for me I hate the customise interface, and can only deal with
(setq ...) stuff.

From etc/NEWS, of course:

   ** All the default-FOO variables that hold the default value of the FOO
   variable, are now declared obsolete.

Really ALL those variables beginning with `default-', such as:

--8<---------------cut here---------------start------------->8---
    (setq default-case-fold-search t)
    (setq default-directory "XXX")
    (setq default-frame-alist '((tool-bar-lines . 1)))
    (setq default-enable-multibyte-characters t)
    (setq default-input-method "latin-1-prefix")
    (setq default-major-mode 'org-mode)
--8<---------------cut here---------------end--------------->8---

Is, then, the following correct starting from Emacs 23.2?

--8<---------------cut here---------------start------------->8---
    (setq-default case-fold-search t)
    (setq-default directory "XXX")
    (setq-default frame-alist '((tool-bar-lines . 1)))
    (setq-default enable-multibyte-characters t)
    (setq-default input-method "latin-1-prefix")
    (setq-default major-mode 'org-mode)
--8<---------------cut here---------------end--------------->8---

Thanks for giving this precision...

Best regards,

(info "(emacs) Useless Whitespace")
     To enable this feature, set the buffer-local variable
  `indicate-empty-lines' to a non-`nil' value.  The default value of this
  variable is controlled by the variable `default-indicate-empty-lines';<---Hey, isn't that deprecated?
  by setting that variable, you can enable or disable this feature for
  all new buffers.  (This feature currently doesn't work on text-only
  terminals.)<---So that's why I can't see the tildes, and not due to trying vim.

No, only those variables that hold the default value of the FOO variable.  E.g.
there is no `directory' variable.

Try: C-h d \`Default value of

Right. Of course, that seems obvious now that it is said!  Indeed...

I don't understand why, but even without the backquote, I have an error when
trying the above command:

--8<---------------cut here---------------start------------->8---

CUSTOMIZE: Re: how to turn on showing end of file?

I myself have never been able to profitably use the
customize interface.

MY problem is that, as with many menu-driven gui-interfaces (eg
   main --> syntax --> foo-words --> regexp-search-for-special-word--FOO ),

is that I have no idea how to find anything, no idea of where to 
even look for something.

What would be *really* nice would be a command that, starting
at whatever customize-node you're corrently at, would draw (indented text)
the entire "subtree" of it, all the way down to the leaf items.

AND really nice if also could output a .pdf-file of it -- and
if it turned out that same leaf item occurred under several
subtrees, so the tree became a directed graph, then via
some nifty-clever graph-drawing algorithm (such as at
Brown univ's site devoted to them), something we
could browse over via mouse, zoom, etc, even print out,
scotch-tape pages together, and hang on wall.

Plus the probably impossible: when new items added, some
kind of (graphic?) diff?

Otherwise, for me it's *info* and M-x Occur on the index,
that kind of thing.


PLEASE -- SOMEONE make customize easier to find things in!

Thanks!

David

A couple of things that may make customize easier for you

1. M-x customize-group. All customizations are part of a group. These
groups are in a hierarchy with the group 'emacs' at the top. Using this
command, you can jump into just a specific group. For example, if you
wanted to customize things relating to ecb, you would enter ecb at the
prompt for M-x customize-group. You also have completion available, so
you can see what groups exist. 

2. Generally speaking, if you do a 'describe' on a variable, if that
variable has a 'customize' interface, it will have a line in the output
saying sometihghin like

"This variable can be customized'

where customized is underlined and is a hyperlink. Clicking on it will
bring up the customize buffer for that variable. 

3. You also have  a lot of other customize functions that will provide
   you with lots of other ways to work with customize, such as

   M-x customize-variable, which gives the customize interface for a
   specific variable
   M-x customize-apropos which does a apropos just for customize
   variable
   M-x customize-face to customize a specific face. By default, it will
   do the face under point.
   m-x customize-option

and then there are a heap for selecting variables that have been set
through customize, ones that have not been set etc.

While it took me a long time to switch to using customize, now that I
have, its really useful - especially the cusotmize-group command. I've
also found that in some cases, setting the value through customize gives
much better/more reliable results than doing it via elisp in my .emacs
file. Not sure why there is a difference, but in some cases, there
certainly is.

OK, thanks.

I'll have another go at customize!
