Hello,
I'm using Nikola (https://getnikola.com/) with its orgmode plugin to
write blog posts. Their script contains following custom link for HTML
export:
(defun org-custom-link-img-url-export (path desc format)
(cond
((eq format 'html)
(format "<img src=\"%s\" alt=\"%s\"/>" path desc))))
(org-add-link-type "img-url" nil 'org-custom-link-img-url-export)
And I have org-mode contents like this:
#+CAPTION: some caption for the image
#+ATTR_HTML: width="60%"
[[img-url:/img/a.jpg]]
I found that somehow DESC parameter passed to above
org-custom-link-img-url-export function contains all information
regarding CAPTION and ATTR_HTML but unable to retrieve it properly. Is
there any org utility functions to retrieve them? For example, I want
to access 'width' parameter from ATTR_HTML like this:
(defun org-custom-link-img-url-export (path desc format)
(cond
((eq format 'html)
(let ((width (SOME-FUNCTION desc :width)))
(if (null width)
(format "<img ... width=\"%s\"/>" ... width)
(format "<img .../>" ...))))))
Could you help me how to do that?
Thank you.
