Org reader support for ATTR_HTML

[bosmacs]

Similar to #1877, it would be nice for the org reader to support #+ATTR_HTML. This was mentioned on pandoc-discuss a while back, and seems useful for adding arbitrary HTML attributes to non-header elements; take images, for example:

#+CAPTION: A black cat stalking a spider
#+ATTR_HTML: :alt cat/spider image :title Action! :align right
[[./img/a.jpg]]

Agreed, this would be a very nice addition. I'm swamped with work, so any help is highly appreciated.

Which reminds me: that the smart quotations issue, which you raised, is still open, too. Sorry about that.

👍 I'm not a haskellite, but I'll take a look when I get a chance.

👍 a workaround would be good. I'd just like to be able to add attributes to my revealjs <section>s (e.g. background images / videos / etc)

[fommil]

workaround, it's evil (you need to know the id of the thing you want to change):

#+BEGIN_HTML
<script type="text/javascript">
document.getElementById("shapeless").setAttribute("data-background", "./images/brucelee.jpg");
</script>
#+END_HTML

[fommil]

wow, nice! This will really help out next I'm writing a talk.

[fommil]

will this work for the reveal.js <section>s too?

[tarleb]

How are section marked in org-mode? Could you give me a brief example?

The current code only works with figures, but it should be easy to add this to any element as long as the respective pandoc element has an Attr. This means it could be added to Div, CodeBlock, or Header. Org-mode ignores it for headers (would require a :PREFERENCES: block), so Div and CodeBlock would work.

[fommil]

They are level 1 or 2 headings in org-mode, when rendered to revealjs. I can point you at some talks if that helps but actually the simply example on the pandoc website might be enough.

[tarleb]

K, thx. Sounds like some basic support for :PREFERENCES: blocks is required to get this working. I will take another look at #1962 and #1984 over the next days.

It would be fairly easy to get this working with ATTR_HTML but that would not be comparatible to Emacs, so I'd rather not do that.

Is this really resolved?

#+ATTR_HTML: :title atitle
#+BEGIN_myclass
test
#+END_myclass

should resolve to

<div title="atitle" class="myclass">
<p>
test
</p>

</div>

however, the generated json does not contain the title:

{"t":"Div","c":[["",["myclass"],[]],[{"t":"Para","c":[{"t":"Str","c":"test"}]}]]}

[tarleb]

This issue was mainly about figures. Please open a new issue for adding this to blocks in general.
