Subject: accessing ATTR_HTML and CAPTION from custom
Date: Fri, 9 Mar 2018 19:53:49 -0800	[thread overview]
Message-ID: <5095d0b6-787e-1ac0-fd71-2c1e73454d22@gmail.com> (raw)

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.
