Hi Miro and Bastien,

This can be done by setting the function
`org-make-link-description-function'. However when set, the function
is supposed to handle all type of links and return a string no matter
what. There is no fallback mechanism. Here is a patch that fixes it:


diff --git a/lisp/org.el b/lisp/org.el
index bdb85de..3630623 100644
--- a/lisp/org.el
+++ b/lisp/org.el

            (setq desc path))))

     (if org-make-link-description-function
-       (setq desc (funcall org-make-link-description-function link desc))
-      (if default-description (setq desc default-description)
-       (setq desc (or (and auto-desc desc)
-                      (read-string "Description: " desc)))))
+       (setq desc (or (funcall org-make-link-description-function link desc)
+                      desc)))
+
+    (if default-description (setq desc default-description)
+      (setq desc (or (and auto-desc desc)
+                    (read-string "Description: " desc))))

     (unless (string-match "\\S-" desc) (setq desc nil))
     (if remove (apply 'delete-region remove))


For example my `org-make-link-description-function' is:

    (setq org-link-to-description
          '(("\\`file:.*/\\([^/:]+\\)\\(::.*\\)" . "\\1")
            ("\\`file:.*/\\([^/:]+\\)" . "\\1")))

    (setq org-make-link-description-function
          (lambda (link description)
            (let ((found (assoc-default link org-link-to-description
'string-match)))
              (cond
               ((stringp found) (match-substitute-replacement found t
nil link))))))


HTH,

Sylvain.
