Hi folks,
I apologize fro relying on your charity for htis question -- I ought to
figure this out myself, but am so slow that I've run out of time.
I dhave a number of lecture slides writen in org-mode. Normally I simply
export to reveal.js using org-reveal. However, I now have to share these
notes with a co-instructor who uses markdown, but not org. This is not
fatal; I can export to markdown mode and use pandoc to create the reveal.js
slideshows.
However, there are two small difficulties:
a) add a horizontal rule
pandoc expects a horizontal rule at each slide division. So, if possible,
I would like to add an hhr element at the end of every headline.
b) speker notes
More importantly, org-reveal allows the use of speaker notes, thus:
#+BEGIN_NOTES
whatever I put here
#+ END_NOTES
is exported as:
<aside class="speaker-notes">
whaever I put here
</aside>
However, these blocks are ignored by the markdown exporter.
Presumably I need to add a filter, or build a very simple derived backend,
but my attempts thus far haven't been very successful. I would really
appreciate some suggestions! Thank you,
matt

What’s a hhr element?
Can you just use something like
---------------------------
for a horizontal rule? AFAIK, it’s inserted as "---".

For me it’s inserted as
<div class="notes">
whatever I put here
</div>

The point is that I have lots of these lecture notes, and would prefer not
to alter them too severely if possible.

yes, that's right, I was being hasty. In any case, what I would like to do
is reproduce this behaviour in the markdown export; I have tried modifying
the md export but I am doing something wrong, clearly, and had hoped to get
some hints from the list...

Err, what about
--8<---------------cut here---------------start------------->8---
#+MACRO: hhr #+MD: ---
* abc
first slide
{{{hhr}}}
* def
second slide
{{{hhr}}}
--8<---------------cut here---------------end--------------->8---

Ok here is a hint. You can add a menu item if you really need it.
--8<---------------cut here---------------start------------->8---
#+BEGIN_SRC emacs-lisp
(org-export-define-derived-backend
'md-plus
'md
:translate-alist '(
(export-block . org-md-plus-export-block))
:export-block '("NOTES"))
(defun org-md-plus-export-block
(export-block contents info)
"Transcode a EXPORT-BLOCK NOTES element from Org to md-plus.
CONTENTS is nil. INFO is a plist holding contextual information."
(if (equal (org-element-property :type export-block) "NOTES")
(concat "<aside class=\"speaker-notes\">\n"
(org-element-property :value export-block)
"</aside>\n")
(let ((parent-backend (org-export-backend-parent backend)))
(if parent-backend
(org-export-with-backend
parent-backend export-block contents info)))))
#+END_SRC
#+BEGIN_NOTES
just for the note takers...
#+END_NOTES
: Run like this
: M-x (org-export-to-buffer 'md-plus "***md-plus-out***")
--8<---------------cut here---------------end--------------->8---
HTH,
Chuck

In that case I would indeed use a filter and run it conditional on the
file path, available through the info plist.
You could can add lines via org-export-before-processing-hook. Combine,
outline-next-heading (or just re-search-forward and org-heading-regexp),
check with org-element-at-point or org-outline-level and go to the end of
the headline and insert your line (if you use org-element-at-point for
this, remember to skip backwards through the " \n\t").

It gives a div already with ox-md, right? What do you want more? Do you
want it to be an <aside ...></aside ...> element? If so, use a filter on
org-export-filter-special-block-functions that does a regexp replacement.

Hi, I realize I never responded to say thank you.
This is a big help, and I now have things working the way I like!
