Hello all,
when I export a drawer to LaTeX, the output from
org-latex-format-drawer-function, which I can re-define, is inserted
directly into the LaTeX document. In particular, it is not considered a
different paragraph by default.
When I export to odt, the content text passed to the
org-odt-format-drawer-function is already wrapped within a paragraph
style, e.g.:
<text:p text:style-name="Text_20_body">Drawer contents here
</text:p>
This inconsistency is not ideal. I would prefer the contents to be
passed to the drawer function without this wrapping style. I don't mind
if the default of the function puts the contents in a paragraph, of
course, but I would like to override this.
I've gone through the code but cannot determine where this is done and
why the ODT export target is treated differently to the LaTeX one.
Any pointers would be welcome.
Thanks,
eric

Both are treated similarly, really. The difference comes from the fact
that LaTeX has no markup for paragraph. Therefore,
:drawer:
Paragraph 1
Paragraph 2
:end:
will become
Paragraph 1
Paragraph 2
in LaTeX, but
<p>Paragraph 1</p>
<p>Paragraph 2</p>
in HTML...
You could write a drawer filter trimming paragraph markup if the drawer
consists of a single paragraph (e.g., no blank line).

Hi Nicolas,
this is not quite true; in LaTeX, a blank line (\n\n) indicates a
paragraph but org does not treat a drawer as starting a paragraph. E.g.
#+begin_src org
,#+options: d:test
,* testing
This is the first paragraph.
:test:
This is a test.
:END:
#+end_src
generates
\section{testing}
\label{sec:org499dcbc}
This is the first paragraph.
This is a test.
\end{document}
and this is what I want as I can put a blank line before the start of
the drawer should I want a new paragraph.

I could but this is not achieving consistency across the export targets
and would not allow for a single paragraph drawer to be exported inline
or as a separate paragraph.
Thanks,

Of course it does. Drawers contains paragraphs, not the opposite way.

To convince yourself, you could put point at the beginning of the first
paragraph and evaluate
(goto-char (org-element-property :end (org-element-at-point)))

Again, you are confused because LaTeX treats blank lines specially. The
"latex" back-end preserves blank lines from the original file. So in
this case, the absence of blank lines makes it think there is a single
paragraph. However, it wasn't the case in the source document.

Hi Nicolas,
We may have to agree to disagree here. The export outputs indicate the
opposite. I understand your reasoning (as given in the rest of the
post) but I think there is a fundamental design issue here. However, I
can live with it.
So, moving forward, is there an ODT expert that can tell me how to wrap
the contents of a drawer so that the background of the drawer contents,
which obviously consist of 1 or more paragraphs on ODT export, is a
specific colour? I tried:
#+begin_src emacs-lisp :results none
;; format note drawers
(setq-local org-latex-format-drawer-function
(lambda (name contents)
(if (string= name "note")
(progn
(format "\\hl{%s}" contents)))))
(setq-local org-odt-format-drawer-function
(lambda (name contents)
(if (string= name "note")
(progn
(format "<text:span text:background=\"#FFFF00\">%s</text:span>" contents)))))
#+end_src
but this leads to malformed XML according to libreoffice. The LaTeX
works because I expect note drawers to be short and no more than a
single "paragraph". For other drawers, I used mdframed in LaTeX to
achieve a similar effect.
(ignore the emacs lisp correctness/style issues... e.g. progn and what
happens if a different drawer; this is work in progress ;-))
This is all relates to my preemptively moving away from inline tasks for
a number of use cases.
Thank you.

I'm not sure what we have to agree to disagree on.
I'm just describing how the Org syntax works. This is documented at
<https://orgmode.org/worg/dev/org-syntax.html>.
For the record,
p1
:drawer:
p2
:end:
p3
is seen as
'((p1) (drawer (p2)) (p3))
But maybe I'm misunderstanding and you have something else in mind.

:-)
I think simply that the outcome on export is qualitatively different
depending on target: for LaTeX, the drawer is not (necessarily) a new
paragraph whereas for ODT it is. This bothers me æsthetically and does
make writing filters etc. more difficult but it's not a deal breaker!
> I'm just describing how the Org syntax works. This is documented at

Yes, I understand. I am definitely not disagreeing about how org parses
the elements, simply how it exports them.
thanks,

Then we agree on this point.
Export is different because, well, target languages are also
different...
Since empty lines are preserved upon exporting documents, Org is /de
facto/ nice with formats that separate paragraphs with blank lines,
e.g., LaTeX or Texinfo. I.e, it adapts easily to their definition of
a paragraph.
As you noted, this is not the same for other back-ends, as HTML or ODT.
At some point, I wanted to have Org adapt to their own definition of
a paragraph. I.e., a parse-tree filter (provided by the back-end) would
generate pseudo-elements matching the target's definition of
a paragraph. Then, the parse-tree would convert the pseudo-element as
a paragraph whereas it would do nothing for a regular paragraph.
E,g., the following document
Paragraph
#+begin_quote
Quote
#+end_quote
Paragraph 2
Paragraph 3
is parsed as
(paragraph "Paragraph")
(quote-block (paragraph "Quote"))
(paragraph "Paragraph 2")
(paragraph "Paragraph 3")
the HTML parse tree filter would turn it into
(html-paragraph
(paragraph "Paragraph")
(quote-block (html-paragraph (paragraph "Quote")))
(paragraph "Paragraph 2"))
(html-paragraph
(paragraph "Paragraph 3"))
and since regular paragraph converter would be a no-op, this would
really become:
(html-paragraph
"Paragraph"
(quote-block (html-paragraph "Quote"))
"Paragraph 2")
(html-paragraph "Paragraph 3")
Some parts of the export framework already implement a similar
mechanism, e.g., `org-latex--wrap-latex-matrices'.
But there are a some shortcomings. E.g., is an `html-paragraph' nested
in an `html-paragraph' still valid? What about the quote block being
a table, a plain list? IOW, what is the exact definition of HTML
paragraph?
Since I couldn't answer those questions, I'm mostly a LaTeX guy, this is
not implemented so far.

Yes!

Which makes consistency challenging. We're seeing this with the
citations thread.

Which is fine with me as I also am a LaTeX guy... :-)
I only need odt when I am sharing with some colleagues that have not yet
seen the light. ;-)
thanks for the detailed explanation in any case.
