What might ‘org-element-at-point’ be doing in *scratch*?

What might ‘org-element-at-point’ be doing in *scratch*?

[Christian Moe]

Hi,

After upgrading to 9.7.1 on Emacs 27.1, I get a curious warning on Emacs
start-up:

"Warning (org-element): ‘org-element-at-point’ cannot be used in non-Org
buffer #<buffer *scratch*> (fundamental-mode)"

It does not happen with 'emacs -Q', but it also did not happen before
the upgrade, so I don't know what in my configuration now triggers it,
or why anything would want to do this.

Anyone else seeing this?

Yours,
Christian

Try M-x debug-on-entry org-element-at-point and you may then get clues
from the backtrace.

Thanks! Nothing the matter with Org; pardon the noise.  Culprit found:
some old code of mine that called org-get-id on load for bad reasons,
and which Emacs has so far suffered in silence.

I also started to see this.  I too traced it to some of my own
coding where I was doing some fancy reformatting of the "*Org
Agenda*" buffer with a definition of org-agenda-prefix-format
that called my user function with an argument including
(org-get-outline-path).  This now gives the above warning
because *Org Agenda* is not an org buffer per se.

I worked around it by removing the custom code which was
pretty awkward in any case.  It does however leave open the
question about whether there are or are not legitimate cases
for org-element-at-point in buffers which are not org buffers
but present summary or custom views of org material like the
agenda.

Yes, calling `org-element-at-point' in non-Org buffers is most likely a
mistake - `org-element-at-point' either returns nil, a garbage, or errs
in non-Org buffers.
