Custom links not handled in headlines #26
Description
Hi,
I currently have some custom org links in my documents successfully translated by a
(org-link-set-parameters "custom" :export 'fn) function when exporting with pandoc.
Recently I tried to put one in a headline, but nothing happened.
Consider this exemple org file:
#+title: Demo
* This [[id:mytarget][won't work]]
This [[id:mytarget2][will work]]
With this configuration:
(defun handle-id-links (target-id description backend)
(when (eq backend 'pandoc)
(format "[[https://mydomain.com/%s][%s]]"
target-id
(or description target-id))))
(org-link-set-parameters "id" :export #'handle-id-links)When exporting to html with pandoc for example, this comes out:
<body>
<h1 id="this-wont-work">This <a href="id:mytarget">won't work</a></h1>
<p>This <a href="https://mydomain.com/mytarget2">will work</a></p>
</body>Actually, if I remove the link in the paragraph, and tell edebug to eval handle-id-links, I found that this function will never be called during export.
Instead, it will be handled by org-org-headline in ox-org.el, finally calling org-element-link-interpreter which doesn’t do anything with the custom link.
I found a workaround by bypassing org-element-link-interpreter like this, but maybe this is something ox-pandoc could handle?
;;Workaround
(defun custom-link-interpreter (link contents)
(let ((type (org-element-property :type link))
(path (org-element-property :path link)))
(when (string= type "id")
(handle-id-links path contents 'pandoc))))
(advice-add #'org-element-link-interpreter :before-until #'custom-link-interpreter)
