I've been struggling with this for a while, and am a mediocre programmer, so thought I'd ask for help here. I started out writing this generate capf to insert citation keys, but have decided to make it specific to org-cite. Here's the commented function. TIA. Note the "candidates" variable accesses a cached alist, of the form: ("long search string with title, author, etc." . "citekey") So I want the user to be able to select on the car, but insert the cdr. --8<---------------cut here---------------start------------->8--- (defun bibtex-actions-complete-key-at-point-oc () "Complete org-cite citation key at point. When inserting '@' in a buffer the capf UI will present user with a list of entries, from which they can narrow against a string which includes title, author, etc., and then select one. This function will then return the key 'key', resulting in '@key' at point." ;; FIX exit-function is wrong; results in "no match" ;; TODO tighten this regex for org-cite (when (looking-back "@[a-zA-Z]+" 5) (let* ((candidates (bibtex-actions--get-candidates)) (begin (save-excursion (backward-word) (point))) (end (point))) (list begin end candidates :exclusive 'no :exit-function (lambda (chosen status) (when (eq status 'finished) (cdr (assoc chosen candidates)))))))) --8<---------------cut here---------------end--------------->8---
