Problems with attachment links in exported files

Problems with attachment links in exported files

Hi everyone!

I've had a trouble with attachment type link on exporting. I configured
org-attach directory and using org-id and it works great on emacs, all
those links work great. I can see any attach linked on org notes, but in
exported files all those links point to local directory instead of the
right attached folder.

I read this article (
https://vxlabs.com/2020/07/25/emacs-lisp-function-convert-attachment-to-file/)
which talks about that "org-attach-export-link" function will be removed.
I've tried to convert attachment to file links, and it works fine. But I'd
prefer to use attachment links instead of converting them.

I also read this thread (
https://lists.libreplanet.org/archive/html/emacs-orgmode/2020-02/msg00784.html),
but I'm quite sure if all these changes all actually implemented on
org-mode. I tried to use

(add-hook 'org-export-before-parsing-hook 'org-attach-expand-links)

And it works except for inline images, but I don't understand why is not on
org-mode repository code.

Thanks you in advance!. Best regards!

P.D.: I also tried to look up more information about this problem on this
list, I couldn't find anything on the list searcher.

Hmm, I'm not sure what you mean by the last part.  The snippet you show
is in the Org repo, specifically in org-attach.el:

  https://code.orgmode.org/bzg/org-mode/src/release_9.4.4/lisp/org-attach.el#L750

I'm not an org-attach user, so I might be missing something obvious, but
I wasn't able to trigger the issue with inline links.  Here's what I
tried using the default configuration on the master branch (c3888a8b7):

  (require 'org-attach)
  (let ((default-directory (make-temp-file "org-attach-export-test-" t)))
    (with-current-buffer (find-file-noselect "scratch.org")
      (insert "* h1\n\n")
      (org-attach-url
       "https://orgmode.org/worg/images/agenda/org-agenda-colorized-blocks.png")
      (insert "attachment:org-agenda-colorized-blocks.png")
      (org-open-file (org-html-export-to-html))))

That output includes

    <img
    src="file:///tmp/org-attach-export-test-Surcu0/data/ad/4bdf8f-a28e-4621-a1e4-dc772ed6d531/org-agenda-colorized-blocks.png"
    alt="org-agenda-colorized-blocks.png" />

and the image is rendered inline.

Could you provide a minimal reproducer for the issue you see?

Thanks Kyle!, While I was reading your message I checked that my org-mode
version was outdated. I configured org-mode repository, but I didn't
install the latest org-mode version. So I'm sorry for that. I've tried your
snippet, and it works perfectly. Thank you for you time, I appreciate it.
