What are the possible element containers

Sections

Sections are divided by headlines.

  Zeroth section
  * First headline
  First section
  ** Child headline
  Child section
  * Second top-level headline
  Second top-level section

Greater blocks

  #+begin_center
  elements
  #+end_center

Drawers

  :drawername:
  elements
  :end:

Dynamic blocks

  * Headline
  #+BEGIN: clocktable :scope subtree :maxlevel 2
  #+CAPTION: Clock summary at [2023-04-16 Sun 16:13]
  | Headline     | Time   |
  |--------------+--------|
  | *Total time* | *0:00* |
  #+END:

Footnote definitions

  [fn:1] A footnote definition.

  [fn:2] A multi-line

  footnote definition.

Plain Lists

  1. foo
     1. bar
  2. baz

Which container takes priority

This test interleaves the opening and closing of each element container to see which element becomes parsed vs gets broken up. The row determines the first opening element and the column determines the second opening element.

	Section	Greater Block	Drawer	Dynamic Block	Footnote Definition	Plain List	Paragraph
Section	-	Section	Section	Section	Section	Section	Section
Greater Block	Section	First	First	First	First	First	First
Drawer	Section	First	First	First	First	First	First
Dynamic Block	Section	First	First	First	First	First	First
Footnote Definition	Section	First	First	First	-	-	-
Plain List	Section	Second	Second	Second	-	-	-
Paragraph	Section	Second	Second	Second	-	-	-

Possible solutions

Greater blocks, drawers, and dynamic blocks disable plain list exit matcher

Test Case 1

  1. foo
     #+begin_center
     2. bar


     baz
     #+end_center

Parse out headlines first

Then go through elements parsing them in-order

Should paragraph exit matcher apply to the element matcher in the exit matcher

No. But paragraph exit matcher needs to apply to the object matcher.

Maybe two groups of elements: alpha and beta

When entering an alpha element, ignore beta exit matchers above this in the context.
