Problem with custom links

Problem with custom links

[Thomas S. Dye]

Aloha all,

Recently, custom links that I've used for years changed their 
behavior.  They used to behave like other org mode links, but now 
they are displayed in a different color face and are always fully 
displayed, unless I add two new keywords to 
org-link-set-parameters.

  (org-link-set-parameters
   "parencite"
   :follow 'org-ebib-open
   :export (lambda (path desc format)
             (cond
              ((eq format 'html)
               (format "(<cite>%s</cite>)" path))
              ((eq format 'latex)
               (if (or (not desc) (equal 0 (search "parencite:" 
               desc)))
                   (format "\\parencite{%s}" path)
                 (format "\\parencite[%s][%s]{%s}"
                         (cadr (split-string desc ";"))
                         (car (split-string desc ";")) path)))))
   :display 'org-link
   :face 'org-link)

I added the :display and :face keywords after I stumbled upon a 
list of defined links (which I wish I'd noted because I haven't 
found it since) that indicated that :display was set to 'full 
(which confused me because I'd read that the default was supposed 
to be 'org-link).  Adding these two keywords restores the original 
behavior for me.

I'm wondering why I have to set these keywords to get the default 
behavior?

I did search ORG-NEWS for a relevant entry, but didn't see 
anything that rang a bell.

I hope you and yours are well in the face of the pandemic.

Let me know if you have questions.

All the best,
Tom

I tried this snippet, dropping the :display and :face arguments

  (org-link-set-parameters
   "parencite"
   :follow 'org-ebib-open
   :export (lambda (path desc format)
             (cond
              ((eq format 'html)
               (format "(<cite>%s</cite>)" path))
              ((eq format 'latex)
               (if (or (not desc) (equal 0 (search "parencite:" 
                                                   desc)))
                   (format "\\parencite{%s}" path)
                 (format "\\parencite[%s][%s]{%s}"
                         (cadr (split-string desc ";"))
                         (car (split-string desc ";")) path))))))

with the following buffer:

  [[parencite:foo][bar]]

With an otherwise default configuration and the current master
(49364f904), the link gets fontified with the org-link face and
displayed as just "bar".  So, that seems to be behaving as expected and
I don't spot any relevant code change to the handling of the defaults in
org-activate-links.

Have you tried to trigger it without any additional configuration?

Aloha Kyle,

Thanks for taking a look at this, and also for the instructions 
how to test.  I get the results you report.

Separately, off list, John Kitchin kindly noted that my symptoms 
might be caused by org-ref.  A bit of snooping led me to 
understand that org-ref was installed on my system as a dependency 
of emacs-reveal, so the mystery is solved.

I'm happy using the two new keywords; they seem to protect my 
setup from being changed by org-ref.

All the best,
Tom
