Cannot link to files with no extension

Cannot link to files with no extension

[Colin Baxter]

Org-mode cannot link to files without an extension. I therefore cannot
use org-store-link for org-journal files, etc.

Best wishes,

Colin Baxter.

I'm not able to reproduce this on the latest main branch. I tried this with
Emacs 28.0.91:

Opened the COPYING file from org-mode repository.
Executed M-x org-store-link
Created test.org and did C-c C-l.

I was able to create a link and open it with C-c C-o.

Can you add more details like version, and steps to reproduce with
emacs -Q?

Thanks for your reply.

1. Touch two files in some directory:
   touch a.org <RET>, touch z <RET>

2. emacs -Q <RET>

3. C-x f a.org <RET> and C-x f z <RET>

4. Write some text in each file
   (I suppose this is not really necessary).

5. Close the buffer z.

6. In a.org enter [[file:./z][This is file z]] and save.

7. Click on the link.

8. Message "Running less in /path/to/z ... done", but link does not
   open.

9. I get the same if I use C-c C-o.

10. Copy z to z.org.

11. In a.org enter [[file:./z.org][This is file z.org]] and save.

12. Link now opens if it's clicked or C-c C-o is used.

This test was done with emacs-29.0.50 and org-version 9.52. I'm on
Debian 4.9.290-1.

I hope this helps.

Best wishes,

Colin.

This sounds like your `org-file-apps' is funny. What is its value?
Check also the value of the system-specific variable
`org-file-apps-{gnus,windowsnt,macos}' - whichever is applcible to your
case.

That should be `org-file-apps-{gnu,windowsnt,macos}'.

I have not altered (knowingly!) my 'org-file-apps' for years. Its value
is:

--8<---------------cut here---------------start------------->8---

Value:
(("\\.pdf\\'" . "xpdf %s")
 (auto-mode . emacs)
 ("\\.x?html?\\'" lambda
  (file link)
  (eww-open-file file))
 ("\\.pdf\\'" . system)
 ("\\.dvi\\'" . system)
 ("\\.ps\\'" . system))

Original value was 
((auto-mode . emacs)
 (directory . emacs)
 ("\\.mm\\'" . default)
 ("\\.x?html?\\'" . default)
 ("\\.pdf\\'" . default))

--8<---------------cut here---------------end--------------->8---

The odd thing is that my problem has just arisen. I don't remember
having it before say a few weeks ago.

Best wishes,

Colin.

I see the problem using emacs -Q, as I reported in a previous email.

It turns out I was clicking the wrong mouse button. On my setup, the
right-hand mouse button opens files 'b' and 'b.<extension>',
whereas the left-hand button only opens links to 'b.<extension>'. I was
not aware that the behaviour of org-mode links was mouse-button
dependent.
