[ox, patch] Quickly INCLUDE from own file

[-- Attachment #1: Type: text/plain, Size: 880 bytes --]

Hi,

The attached patch allows for "quick" (== without filename) inclusion
from the same file.  Why?  'Cause I'm lazy and it would be useful to
push boring, location-specific stuff to the end of the file.

Here's an example:

    * poor man's ~:ignoreheading:~
    #+INCLUDE: "::*foo" :only-contents t

    #+INCLUDE: "::tbl"

    * foo                                                   :noexport:
    1

    * bar                                                   :noexport:
    #+NAME: tbl
    | 1 |

You need the preceding "::" to be able tell the difference between the
file "tbl" and the table "tbl".  Granted, this doesn't look like an
org link.  If that's an issue, for each link sans location it could be
tested if it exists in the current buffer.

Do you think something like this would be desirable?

Including in the same file is dangerous: you can easily duplicate
custom-id, name keywords, which are supposed to be unique. Even though
we don't prevent it[fn:1], I don't think we should make it easier to achieve.

Introducing a new special syntax in this case doesn't sound like a good
move either.


Regards,

[fn:1] Actually, we should have a guard against circular inclusion, but
at the moment, it is ineffective in this case.
