link handling for `file:' fails to stay within Emacs but calls `open file:' with TextEdit

link handling for `file:' fails to stay within Emacs but calls `open file:' with TextEdit

[Van L]

Hello.

The link handling for org mode behaves unexpectedly where a file sets
org mode according to `Local variables:' at the end of the file.

In the following, a.org and b.org files work as expected using M-x
org-store-link and M-x org-insert-link for `file:' link.

Without the .org filename extension, following the link calls

  `open file:' which leads to Org Mode opening the file with TextEdit

under mac os, Emacs 26.1 rc-1.


;;;; ------------------------------------

;; running	: Emacs.app/Contents/MacOS/Emacs -Q
;; problem	: This two file arrangment for `Emacs -Q' *fails* to follow the link.
;; expect	: Emacs to open a link to org file.
;; unexpected	: Emacs calls TextEdit to open org file.
;; solution	: if file a and b are called a.org and b.org then there is no problem.

;; Solution needs org files named without the `.org’ extension
;; to follow `file:’ links without leaving Emacs.

Files are selected by their extension, not by their major mode. You may
want to tweak `org-file-apps'.

I chose `Default for unrecognized files’, `Visit with Emacs’; 
but `Default for files in directory’ or use of the hidden file in the directory for setting the mode would be better.

Thanks.

I don't understand your answer.

What is your `org-file-apps'? What is not working according to your
setup?

Value:
((auto-mode . emacs)
 ("\\.mm\\'" . default)
 ("\\.x?html?\\'" . default)
 ("\\.pdf\\'" . default)
 (t . emacs))
Original value was 
((auto-mode . emacs)
 ("\\.mm\\'" . default)
 ("\\.x?html?\\'" . default)
 ("\\.pdf\\'" . default))

It is working now since I was advised to look there and I made the above change.

I am now able to link file to file and stay within Emacs for a directory having only files in Org Mode but without the .org filename extension.

To be better, I’d like to set the local directory where emacs opens all the files.

The current setting opens everything unknown to emacs in emacs.

There is a hidden file method to have emacs open files according to the mode set there for the directory.

But the link mechanism doesn’t read that.

Thanks for this.  I had been struggling to figure out why opening an
attachment directory did not use Emacs (it used to just fine but
something changed over the past months).  Adding that last line makes it
work.  

I think having '((t . emacs)) alone will suffice for me.  I mean, why
would I want to invoke something other than Emacs? ;-)
