"#+STARTUP: hideblocks" has no effect?

"#+STARTUP: hideblocks" has no effect?

[autofrettage]

Hi,

I recently read about the #+STARTUP parameter "hideblocks", but it doesn't seem to have any effect in my set-up. All the blocks kept laughing straight in my face. :-(

Any ideas about what could have gone wrong?

I use Org Mode 9.4.5 with Emacs 26.3, and I also tried closing the file and Emacs before I tried.


Cheers
Rasmus

p.s. Setting org-hide-block-startup with local variables is a solution, but not as nice as doing it with #+STARTUP, I'd say.

Are you leaving org-startup-folded at showeverything (the default as of
9.4)?  That will prevent org-startup-folded and "#+startup: hideblocks"
from having an effect:

  (defun org-set-startup-visibility ()
    ...
    (unless (eq org-startup-folded 'showeverything)
      (when org-hide-block-startup (org-hide-block-all))
      ...)

For example, try this:

--8<---------------cut here---------------start------------->8---
#+startup: nofold
#+startup: hideblocks

#+begin_src emacs-lisp
(message "ok")
#+end_src
--8<---------------cut here---------------end--------------->8---

Yes I do.

I must admit I was pig ignorant of that.

Kyle> For example, try this:

Specifying "#+startup: nofold" together with "#+startup:
hideblocks", as suggested, worked like a charm!

Case closed, and I will try to RTFM the next time.

It interacts with org-startup-folded (whose default was changed
recently to 'showeverything'): you need to set the latter to something
other than 'showeverything' in order for hideblocks to be effective.
