fetching the description from a link string

fetching the description from a link string

Hello,

I cannot seem to find in org.el a function that will return the
description part of a link. I'm probably missing it … Could someone tell
me if such a function exists?

Thanks,

Alan

org-element-context on a link will give you what you want.  It lives in
org-element, though.

Something like this when point is on a link,

    (let ((e (org-element-context)))
      (buffer-substring-no-properties
       (org-element-property :contents-begin e)
       (org-element-property :contents-end e)))

Hope it helps,
Rasmus

Thank you for the suggestion. I'm already doing something similar:
#+begin_src emacs-lisp
(let ((link (org-store-link nil))
      (name (org-element-property :raw-value (org-element-at-point))))
...)
#+end_src

For some reason I was under the impression that org-element might be
overkill for this, but it works well.

Thanks again,

Alan

You can also use org-bracket-link-regexp, if you want:

(let ((link "[[http://example.com][Description]]"))
  (and (string-match org-bracket-link-regexp link)
       (match-string 3 link)))
