Unable to follow gnus links

Unable to follow gnus links

[Tom Ed White]

Following gnus links in org fails with the message:

funcall: Wrong number of arguments: ((t) (path _) "Follow the Gnus
message or folder link specified by PATH." (if (string-match
"\\`\\([^#]+\\)\\(#\\(.*\\)\\)?" path) nil (error "Error in Gnus link
%S" path)) (let ((group (match-string-no-properties 1 path)) (article
(match-string-no-properties 3 path))) (org-gnus-follow-link group
article))), 1

The function is org-gnus-open in ol-gnus.el. I found a workaround by
changing the function arguments:

(defun org-gnus-open (path &rest _ moo)

I put the "moo" argument in for testing.

I can eval the original function and run it by itself and it works fine,
so maybe the calling function is passing too many arguments. I believe
the calling function is org-open-at-point from org.el.

I'm running the latest org (20210920) from melpa. The file ol-gnus.el
gets loaded via org module customization.

This should not happen.  Do you open the link using org-link-open?  Can
you share backtrace after M-x debug-on-entry org-gnus-open?

I was able to fix the problem for the time being by changing the
arguments to:

(defun org-gnus-open (path &rest _)

The keystroke I use is C-c C-o, which runs org-open-at-point which is in
org.el.

I understand. But it does not solve the potential problem for other users.

Judging from your backtrace, you seem to have a mixed Org installation
with some files loaded from Org <9.4 (that's when we changed the number
of arguments in :follow functions).

Can you try to re-install Org?

Note that mixed installation can also cause other unexpected problems.

That was it, thank you. I was loading an obsolete version of
ol.el. Hopefully I've found and eliminated all obsolete org code.
