ah, ok.  Now I will reveal some of the depths of my ignorance.  Looks like
:attr_html is a plist (right?).
(a) what is the appropriate way to identify an attribute here.  should I
write, e.g.:

#+ATTR_HTML: :data-external-libs "http://underscorejs.org/underscore-min.js"
:class "list of classes"
or:
 #+ATTR_HTML: data-external-libs "http://underscorejs.org/underscore-min.js"
class "list of classes"
or
#+ATTR_HTML: "data-external-libs" "http://underscorejs.org/underscore-min.js"
"class" "list of classes"

And then, if I want to transform this into:

data-external-libs="http://underscorejs.org/underscore-min.js" class="list
of classes"

can I just do something like:
(let ((attributes (org-export-get-attribute :attr_html src-block))
  (cl-loop for (key value) in attributes
    (collect (concat key "=" "\"" value "\" " ))))

or do I need to transform the key into a string first?
I'm sorry to be writing such basic lisp questions; obviously I need to read
a really good lisp introduction, but I haven't found one yet.

right. Up till now I have been hoping to integrate these change sback into
ox-reveal, but now it's starting to feel a bit invasive.  I may try this
route.

I think this might be the best route, since I would probably want to load
such files on a block-by-block basis.

The answer is still no. ;-)



There are complicated ways. See

for one such. But for what you are doing ATTR_HTML is easiest.


I will take the easiest please! 





I am already rewriting the exporter's src-block export

function, so I can try to accomplish what I need to in that context.





BTW, the cleanest way to do this is by writing a derived exporter:



:=C2=A0 (org-export-define-derived-backend 'reveal 'revealplus=
 ...



In your case you only provide the src-block entry for the :translate-alist,=
 :options-alist entries for any you redefine or introduce, and optionally a=
 :menu-entry.



Also, you'll probably want to add a hook to `org-export-before-parsing-=
hook' (see below).





If you do this, then `#+ATTR_REVEALPLUS:' seems suitable.

2. I'd like to be able to test my code directly in org (since I'm a=

Yes. Depending on what you want one of these:



* Add this to `org-export-before-parsing-hook', perhaps in setting=
 up a

=C2=A0 derived exporter.



* Or perhaps by using a local variable `eval' see



: (info "(emacs) Specifying File Variables")
