Subject: Custom link type that attaches file in :follow
Date: Mon, 12 Apr 2021 09:39:02 +0200	[thread overview]
Message-ID: <87h7kcymsp.fsf@purelymail.com> (raw)


I am having some trouble adding a link via =org-link-set-parameters=.

I want to have a custom =xournalpp=-link type that behaves as follows:
- follow :: Open attached file
  - exists :: open the file
  - don't exist :: create attachment directory and copy template file into it
- export :: Use [[https://xournalpp.github.io/][Xournalpp]] to export the file as an svg. Inline this svg.

#+begin_src emacs-lisp
   :follow (lambda (path)
	     (let ((xoppfile (concat (org-attach-dir-get-create) "/" path))
		   (template "/home/tarjei/repos/konturer/maler/skisse.xopp"))
	       (cond ((not (file-exists-p xoppfile)) (copy-file template xoppfile)))
	       (shell-command (format "xournalpp %s" xoppfile))))
   :export (lambda (path desc backend)
	     (let ((xoppfile (concat (org-attach-dir-get-create) "/" path))
		   (tempfile "/home/tarjei/temp/xournal_export.svg"))
	       (shell-command (format "xournalpp --create-img %s %s" tempfile xoppfile))
		 (insert-file tempfile)


Something seems to go wrong during the export, however, where a new attachment directory is created. Is my assumption that the export will run with =point= at the link incorrect?

All other feedback on the implementation would be much appreciated, I seem to repeat myself way more than should be necessary.
