Hello,
I'm using a function that relies on `org-element-link-parser'. According
to the documentation, the point needs to be at the element of the link
for it to work. I wrote a small function that takes me to the beginning
of a link, but it fails when the point is already at the beginning of
the link. Here is a reproducible recipe showing the problem.
Open this attached tiny org file:
[-- Warning: decoded text below may be mangled, UTF-8 assumed --]
[-- Attachment #1.2: link.org --]
[-- Type: text/x-org, Size: 36 bytes --]
Start
[[file:link.org][link]]
End
[-- Attachment #1.3: Type: text/plain, Size: 385 bytes --]
Put the point on the 'i' of "link", for instance by (goto-char 26).
Look up the context: (org-context). I get ((:link 8 31))
Go to the beginning of the link: (goto-char 8)
Look up the context: (org-context). I get ((:link nil 31))
Is there a reason why the context is different at the beginning of the
link?
Thanks,
Alan

Not what you are asking for, but it is probably wrong to call this
function directly. If you want to parse something, it's better to use
`org-element-context' (or `org-element-at-point' but it doesn't fit
here).

I don't know, but `org-context' is very different from
`org-element-context'. You probably mean to use the latter.

Thank you for the suggestion. The reason I was using `org-context' is
because it is used in `org-next-link'.
Here is what I ended up doing. It works great, but please don't hesitate
to criticize is.
#+begin_src emacs-lisp
(defun as/org-link-p (elt)
(eq 'link (org-element-type elt)))
(defun as/fetch-element-link (elt)
(org-element-property :raw-link elt))
(defun as/fetch-current-or-next-link ()
(let ((elt (org-element-context)))
(save-excursion
(as/fetch-element-link
(if (as/org-link-p elt)
elt
(progn (org-next-link) (org-element-context)))))))
#+end_src
