fold all drawers in a buffer?

fold all drawers in a buffer?

[Matt Price]

Is there a command to fold all drawers in a buffer (all property
drawers would be enough, actually)? Or a suggestion for how to do
this?   Thanks!

They might exist (with me unaware of them), but the following pair of commands
does the job, at least with this minimal test org snippet:

* A
  :PROPERTIES:
  :CUSTOM_ID: a1
  :END:
* B
  :PROPERTIES:
  :CUSTOM_ID: B1
  :END:

#+begin_src emacs-lisp
  (defun org-show-drawers ()
    "Unfold all drawers in buffer"
    (interactive)
    (save-excursion
      (goto-char (point-min))
      (while (not (eobp))
        (and (org-at-drawer-p)
             (org-element-property :hiddenp (org-element-at-point))
             (org-cycle))
        (forward-char))))
  
  (defun org-hide-drawers ()
    "Fold all drawers in buffer"
    (interactive)
    (save-excursion
      (goto-char (point-min))
      (while (not (eobp))
        (and (org-at-drawer-p)
             (not (org-element-property :hiddenp (org-element-at-point)))
             (org-cycle))
        (forward-char))))
#+end_src

#+results:
: org-hide-drawers

I tested the above functions with a big org file - way to slow. 
These versions perfom better, but only on property drawers:

#+begin_src emacs-lisp
  (defun org-show-drawers ()
    "Unfold all drawers in buffer"
    (interactive)
    (save-excursion
      (goto-char (point-min))
      (while (re-search-forward org-property-start-re nil 'NOERROR)
             (and (org-element-property :hiddenp (org-element-at-point))
             (org-cycle)))))

  (defun org-hide-drawers ()
    "Unfold all drawers in buffer"
    (interactive)
    (save-excursion
      (goto-char (point-min))
      (while (re-search-forward org-property-start-re nil 'NOERROR)
             (and (not (org-element-property :hiddenp (org-element-at-point)))
             (org-cycle)))))
#+end_src

This will work on recent versions of org, but the :hiddenp properties
were taken out of the parser by the following git commit (not yet in any
released version of org AFAIK):

commit fe27ca9906f1d6c48a93f463d85850925687b825

For forward compatibility you can skip the visibility check and use
‘(org-flag-drawer nil)’ unconditionally, I think.

I see, thanks for the tip. I did not know about the fate of 'hiddenp' or
about the useful 'org-flag-XXX' functions.
