Hello,
thanks hugely for org mode: the more I learn about it the easier is my
life organization!
I was trying to use org-eww-copy-for-org-mode (org-eww package in the
contrib/ directory) within eww in website like www.indeed.co.uk, and
every time I tried, I was receiving the error "Empty Link".
The error is due to the presence of input forms (e.g., in
www.indeed.co.uk where you can add the job you are looking for), that
are considered like urls by this function [1]. When the input form is
passed to org-make-link-string, org-make-link-string complains that the
link is empty.
Now I solved this by adding an if statement that makes the link only if
the info passed is not nil [2], but maybe someone knows a better check
for org-eww-goto-next-url-property-change than the one using 'shr-url?
Thanks a lot for org mode,
Andrea
[1] org-eww-copy-for-org-mode uses org-eww-goto-next-url-property-change
to get the position of the next link, which uses
(next-single-property-change (point) 'shr-url) which considers input
forms 'shr-url.
[2] this is the fixed version (the only change is highlighted by a FIXED
HERE comment):
#+BEGIN_SRC elisp

"Copy current buffer content or active region with `org-mode' style links.
This will encode `link-title' and `link-location' with
`org-make-link-string', and insert the transformed test into the kill ring,
so that it can be yanked into an Org mode buffer with links working correctly.
Further lines starting with a star get quoted with a comma to keep
the structure of the Org file."

I committed a fix to maint and master. Concretely I simplified your
code to essentially one additional if case.
You are referenced in the commit-message as reporter.
Best regards,
Marco
