I am using org-id to create links to different headlines in an org file. When using org-insert-link (C-c C-l), I select id as the link type option. Then I press RET. I have :complete configured to show a list of headlines from which I select the one I want, I use this:

(defun org-id-complete-link ()
  (concat "id:" (org-id-get-with-outline-path-completion org-refile-targets)))

(org-link-set-parameters "id" :complete #'org-id-complete-link)

Then I press RET and I am prompted for a description. I want the default description to be the headline I just selected from the complete menu. I have found that I can use org-set-link-parameters to specify a default string for this prompt, by using :insert-description followed by a string or a variable or a function. The problem is that I don't know how to use the headline I just selected as the default description.

I am testing this:

(org-link-set-parameters "id" :insert-description "my default description")

I want to replace the string with the headline.

  • For easily reproducing it, it would be nice if you could add the definition of your org-id-complete-link to the question. Anyway, I looked at it, and it seems to me that there is a bug in org-insert-link. Somewhere in that function there is a (org-link-get-parameter type :insert-description), but it receives a type nil when using the :complete method, because in that case the link is set earlier to the value returned by the complete method (while it should be "id" for the org-link-get-parameter to return a non-nil value).

  • If you insert (setq link (concat "id:" link)) just above the line (let* ((type just above that (org-link-get-parameter type :insert-description), then the function defined as the value of :insert-description in your org-link-parameters will get called with a usable non-nil first argument (but the description will also include an id:). Of course it would be great if you could report this bug, possibly with a link to this comment :) Aug 19, 2023 at 8:47
  • I'm not sure if that is a bug. I'm using ID links, which require some configuration to get working. This think this is similar to an http: link or a file: link, where you need to provide the description since there is no default (I might be wrong). The complete method I use provides the link for an ID; I'm wondering if the headline title can be obtained from this, but I have no idea how.
