Re: [O] [RFC] Org document concept + document property drawers

[Gustav Wikström]

Hi again,

Nicolas requested a more thorough introduction to the patch so here it
comes.

To start with, this relates to the topic presented here:
- https://lists.gnu.org/archive/html/emacs-orgmode/2019-06/msg00000.html 

The first patch deals with formalities. It introduces one new greater
element called "document". Parsers and everything around it are
modified to work with this new concept. No new functionality is
introduced. I'd call this patch an "enabler" since it allows us to
(hopefully) reason better about intended behaviors and such moving
forward, but doesn't really do anything. As an example I for one
wouldn't mind to take it even one step further by introducing
"project" as another concept[1]. But that is for another day.

The second patch introduces property-drawers on document level. No
existing code will stop working, i.e. property keywords and all other
keywords will behave just as today.

The first five lines in the following example will work just as
property drawers inside headings with this patch. All commands and
functions that work with "regular" property-drawers are updated to
work also with this document level drawer.

#+begin_src org
  :PROPERTIES:
  :DIR: ~/
  :ID: 730e0151-8e34-4dd9-b978-187c3c81e6b4
  :CATEGORY: Test
  :END:

  Section 1 before first headline.

  ,* TODO Headline 1
  Section 1 in first headline.

  ,** TODO Sub-headline 1                                              :Testtag:
  :PROPERTIES:
  :DIR:      _2018/1809 Spark/
  :CATEGORY: Test-cat
  :END:
#+end_src

I wouldn't be surprised if I've managed to hide a few bugs in the
code. But all tests, and a couple of new ones as well, signal an OK.

Thoughts? Comments?

Kind regards 
Gustav

[1] Sidenote: We already define projects today when we declare that
multiple files together are seen as our "agendas" for example. Or when
we configure publishing. But we lack a common framework for what a
"project" is in our code.
