[BUG] org-link-descriptive not honored as file-local-variable [9.5 (9.5-g0a86ad @ /home/gustavo/.emacs.d/elpa/org-9.5/)]

[Gustavo Barros]

Hi All,

Currently, trying to set `org-link-descriptive' as file-local-variable 
is not honored by Org, and doing so, leads to one of mismatched states 
between `org-link-descriptive' and the invisibility specs.

An ECM for it.  Start ~emacs -Q~ and setup current Org:

#+begin_src emacs-lisp
(add-to-list 'load-path "~/.emacs.d/elpa/org-9.5")
#+end_src

Visit =document.org= containing:

#+begin_src org
[[https://orgmode.org/][Org mode for Emacs]]

# Local Variables:
# org-link-descriptive: nil
# End:
#+end_src

The default value of `org-link-descriptive' is t, and after visiting 
this file, the local variable is indeed set (inspect it, and it tells 
you it is nil).  However, the links are still "descriptive", and 
`buffer-invisibility-spec' does contain `(org-link)'.  Indeed, if at 
that point, you try `org-toggle-link-display', it will fail the first 
time, but work the second one.

a respectful bump.
Despite the changes made to `org-link-descriptive` by Kyle in a
related thread (https://list.orgmode.org/87im4ypu9v.fsf@kyleam.com/),
the failing recipe in this report can still be reproduced in Org 9.5.5
and Emacs 28.2.

Best regards,
Gustavo.

This is because setting things up for links is a part of Org loading
process. And file-local variables are only loaded after major mode by
Emacs. See https://debbugs.gnu.org/cgi/bugreport.cgi?bug=57003

Ah, I had presumed this one would be a load order issue, and indeed it
is a general one. Agreed that this report should stay on standby until
it's been decided what to do in general terms.

And thank you for raising the issue in the Emacs list. Good discussion, btw.

Best regards,
Gustavo.
