Open Outline-mode file in collapsed state

Open Outline-mode file in collapsed state

[bev]

Hi all.

I'd like to figure out a way to open an outline file in it's fully
collapsed state, so that all I see is the headers. As things stand
now, when I open a file in outline-mode it's fully expanded and I have
to run \C-c \C-q - (hide-subtrees) -  to get it into the collapsed
state. It's a bore to have to do that every single time I open one of
those files.

I tried adding (eval-after-load (hide-subtrees)) to the outline-mode-
hook, but that doesn't work.

Any ideas?

Thanks

Bev

I believe you can add the string --

  #+STARTUP: overview 

-- to the very top of your file.  Check the info file:

  (info "(org)In-buffer settings")

Does this work with the regular outline-mode ?

Hi Guys,

I'm not sure what you mean by that. Are you saying add that to the top
of every single outline file I have? (Hundreds). I don't want to do
that. I need a function that will simply run (hide-trees) every time I
open an outline file. I really can't take the time to go add a line to
hundreds of files. Also, I've never seen that before. Is that lisp
code?

Thanks

Bev

No, as I already said, this was a mistake on my part.  I
thought the question was about org-mode.  I am pretty sure
this will not work for outline mode.

Maybe try putting in your .emacs something like 

  (add-to-list 'outline-mode-hook (lambda (hide-sublevels 1)))

I haven't tested it, but I think something like this would
be the answer.

Ah, ok, sorry about not getting the org-mode mistake.
That looks good. I'll try it. In the meantime I figured out one
solution, which seems a little klugey, but it works:

(add-hook 'outline-mode-hook '(lambda ()
       (beginning-of-buffer)
       (outline-next-visible-heading 1)
       (hide-other)
       (hide-subtree)))

Thanks for taking the time to reply to me. I appreciate it. I'll try
your solution as it's more elegant, and seems much closer to THE RIGHT
WAY to do it.

Evans,

Yep, a slight variation of your solution works. I now have in
my .emacs:
(add-hook 'outline-mode-hook '(lambda () (hide-sublevels 1)))

I've never seen that syntax before -- putting a '1' after a function
that takes no args. Does that just mean 'make it so'? I don't know why
just having hide-sublevels without the '1' won't work.

Thanks Evans.

Forgot to quote it.  Sorry.

`hide-sublevels' used non-interactively actually does take
one argument[1].  Its interactive definition must give it some
way around that, since used interactively it behaves as if
it were passed the argument `1'.  I am not sure how it works
after a quick glance.

Ahhhh.... a great light begins to dawn!

Gracias amigo.

Missed that, sorry.

So the right solution is the one you already mentioned:

  (add-hook 'outline-mode-hook '(lambda () (hide-sublevels 1)))


Just out of curiosity: using both an (interactive) form and a mandatory
argument looks unclean to me.  I would expect an (interactive "s") form
when the first argument is not optional (and is expected to be a string)
or only optional arguments when (interactive) is used.  

Is there any clean way to decide on this?

This is for org-mode, not for outline-mode.

(add-hook 'outline-mode-hook 'hide-sublevels)
