[QUESTION] What's the ":desk" link parameter?

[QUESTION] What's the ":desk" link parameter?

[stardiviner]

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA256


I found some examples setting org-link-parameters with ":desk", like this:

#+begin_src emacs-lisp
(defun org-id-link-desk (link desk)
  "Description function for id: link."
  (let ((id (cadr (split-string link ":"))))
    (org-with-point-at (org-id-find id 'marker)
      (s-join "/" (org-get-outline-path 'with-self)))))

(org-link-set-parameters "id" :desk #'org-id-link-desk)
#+end_src

But I have not found any mention in help of variable ~org-link-parameters~. Also I
checked org mode source code by search, no matching of ":desk" found. Did I miss
something?

I don't know.  Probably your chances of getting an answer are higher
if you ask the people who wrote this code?

Where did you find that code?  I recall this was some kind of prototype
code, and maybe it never got fully developed. I think desk was shorthand
for description.

I remember I found this code on emacs.stackexchange.com website.

I did a Google search now, I found someone indeed proposed this feature. Here is
the email archive:

https://lists.gnu.org/archive/html/emacs-orgmode/2019-08/msg00013.html

I saw this thread is stopped. Seems no patch provided. Does anyone want to implement it?

Hi Ihor,

thanks for the patch.  I assume you are submitting it against master,
am I right?

From reading this, I don't see what bug it fixes, what problem it
solves or what real user need it responds to, but maybe I lost part
of the context.  Can you explain why this should be applied?

The patch is against commit 2e96dc639.

It does not fix any bug. Rather adds a new feature [1]. Currently, org
provides org-link-make-description-function as user customisation to
compute default link description. The patch provides a way to set such
description functions on per link type basis (via :description link
parameter). Using link parameters looks natural for me since similar
customisation is already done in :follow and :store link parameters.

I see, thanks.

Okay, I understand.  It feels natural to me too.

I'm not sure `org-link-make-description-function' is used a lot out
there, but the change may break existing configurations/hacks.

Also, is it something we could use in the current export backends
or just for the users?  If the latter, then I'm in favor of making
this move, probably for 9.5.

Nicolas, what do you think?

It should not break anything. I did not remove
`org-link-make-description-function' functionality. Just marked it as
deprecated.

I am not very familiar with the export code, but the function provided
in :description property should follow the same conventions with
`org-link-make-description-function'. The only place it is used is
org-insert-link. I do not see how it can influence export code. As I
understand, org-insert-link is mostly for users.

Best,
Ihor

I agree, I used org-store-link and org-insert-link a lot. If this patch is
applied, then I can add more smart rules to auto generate the description based
on file extension etc.
