no blank lines in org file opened in Emacs on Windows

no blank lines in org file opened in Emacs on Windows

On Linux I can have org open a file and display it like this:

* Local Settings...

* Projects
** Foo

* Something

Notice that it's nice about letting me having blank lines between my top
level headings, even though they are to some degree compacted. I think my
setting is "content" for how expanded it should be.

When I open the same file in Emacs on Windows, with the same configuration
files, I get this:

* Local Settings...
* Projects
** Foo
* Something

There are no blank lines at all, but if I use S-Tab to expand it all out
there are plenty of blank lines.

The file does say it's in Unix mode and I suspect this problem is more
likely caused by a setting I have wrong than a bug. Has anyone seen this
before or have an idea what is causing this behavior?

Thanks,
Scott

You probably have Emacs 21 under Linux and Emacs 22 under Windows.
This is a difference in the implementation of `outline-hide-sublevels' 
between these versions, and Org-mode simply calls this function.

I believe you could take the Emacs 21 definition of this function and 
overwrite the Emacs 22 one by placing the definition into 
outline-mode-hook, but I have not tested this.

 Thanks Carsten, you're right on. I really like the emacs21 behavior a lot
more than that of emacs 22.

 I found a hide-sublevels in outline.el but never found any
outline-hide-sublevels, so I assume they're they same.

(defun hide-sublevels (levels)
  "Hide everything but the top LEVELS levels of headers, in whole buffer."
  (interactive "p")
  (if (< levels 1)
      (error "Must keep at least one level of headers"))
  (setq levels (1- levels))
  (let (outline-view-change-hook)
    (save-excursion
      (goto-char (point-min))
      ;; Keep advancing to the next top-level heading.
      (while (or (and (bobp) (outline-on-heading-p))
         (outline-next-heading))
    (let ((end (save-excursion (outline-end-of-subtree) (point))))
      ;; Hide everything under that.
      (outline-flag-region (point) end t)
      ;; Show the first LEVELS levels under that.
      (if (> levels 0)
          (show-children levels))
      ;; Move to the next, since we already found it.
      (goto-char end)))))
  (run-hooks 'outline-view-change-hook))

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

I gave this a try but it didn't work automatically, and I don't know where
to go from here.

Debugger entered--Lisp error: (wrong-number-of-arguments #[(levels) [A whole
bunch of special characters here]
 [levels outline-view-change-hook beg end 1 error "Must keep at least one
level of headers" nil outline-on-heading-p t outline-next-heading

(prefix-numeric-value current-prefix-arg)) ((save-excursion

Thanks,
Scott

This is a misunderstanding, sorry for not being clearer:
I meant:

(add-hook 'outline-mode-hook
   (lambda ()
     (defun hide-sublevels ......

where the defun .... is the full definition of hide-sublevels from the
emacs 21 outline.  This to override the new definition *after*
loading the old one.

Remember that this is only a hack - maybe a better solution would be to 
use org-cycle-hook and to show those empty lines with a function in 
there.

Carsten,

This hack didn't work for me. How hard would it be to do the second option
and add an option the user could set whether or not to show blank lines in
content and overview views?

Thanks,
Scott
