Feature proposal: Triple square brackets to create a link to a file AND include the file

Feature proposal: Triple square brackets to create a link to a file AND include the file

[ST]

Hello,

it would be nice to be able to make URIs to INCLUDEd files clickable. In
order to make them also lightweight, readable and corresponding to
current link syntax, I would suggest the following:

[[[dir/file]]]
[[[dir/file]] :lines "5-10"]
[[[dir/file][My file]] :lines "5-10"]

as clickable, including links.

What do you think? Or maybe there is already something like this, if yes
- how can I achieve the same?

Thank you!

This does not make sense: include files are not meant to be inlined.
Links are.

Use `C-c '` on a file.

What do you mean by "inlined"? During an export such a link
[[[dir/file]]] should be replaced with the content of the "file", and
the link itself disappear. But in the source .org file it is just
shorter/cleaner way to write 

#+INCLUDE: "dir/file"

and be able to click the link to open the file in a separate buffer.

Why shouldn't it be possible to achieve just the same by ALSO clicking
on the URI? If you use .org files as a wiki - this feature is quite
useful.

Thank you!

Aaa... I see. Actually I don't need it to be in the middle, only at
column 0.

Starting with which version of Org? I have 8.2.10 and it doesn't seem to
work there...

Well, triple square brackets is shorter and cleaner for wiki purposes...
I don't mind it to be able to include files only at column 0, it's
totally OK.

This is different. It is easier to insert text at column 0 than at
a random position in a line. You cannot do the latter in Org.

This is already possible.

Why do you need something else if there is already a way to do what you
want? I'm not a big fan of extending syntax gratuitously.

Then the link syntax is not adequate. What would you do if the triple
bracket horror is on the middle of the line?

Not out of the box, but you can probably add a mouse event on INCLUDE
keywords. And there's a function to visit the file already.

As I said, link syntax is inadequate here. I still think what Org
provides is enough.

+1. Also the proposed link syntax is too confusing with the existing and
also for a very corner use case. And then we need to worry about fontifying
those and existing links correctly, adding support to exporters, etc.

Unrelated:

@ST: btw also please update to the latest Org 9.1.x on maint branch or via
Org Elpa. Version 8.x is too old.

You can get essentially what you want with a custom org-link in org-9 or
later.

#+BEGIN_SRC emacs-lisp
(org-link-set-parameters
 "wiki"
 :follow (lambda (path) (find-file path))
 :export (lambda (path description backend)
	   ;; do this for all exports
	   (with-temp-buffer
	     (insert-file-contents path)
	     (buffer-string))))
#+END_SRC

If you need extra syntax to support the lines below, see
http://kitchingroup.cheme.cmu.edu/blog/2015/02/05/Extending-the-org-mode-link-syntax-with-attributes/
for an approach to do that with the existing link syntax, so it might
look like:

[[wiki:dir/file :lines "5-10"]]

This link is clickable and inserts the file at the link point in the
export.
