I use org to write my lecture notes, and have started using klipse in those
exported notes to execute code snippets in a browser environment (
http://matt.hackinghistory.ca/2016/12/11/org-mode-run-code-live-in-a-reveal-slideshow-with-klipse/
). Sometimes I would like to set up the javascript environment with some
additional libraries, either local or web-based. Klipse lets you do this
with a custom data- attribute.
My questions are:
1. can I pass this html attribute to the <pre><code> block somehow?
ATTR_HTML doesn't seem to work. Is this a bug? If so, should I try to fix
it? If not, is there a simple way to use header arguments to pass
information down? I am already rewriting the exporter's src-block export
function, so I can try to accomplish what I need to in that context.
2. I'd like to be able to test my code directly in org (since I'm a lousy
coder and a clumsy typist). Can I tell org to load other files before
executing a src block?
Thank you!

No and no.
Did you try
: (plist-get (cadr src-block) :attr_html)
in `org-html-src-block' ?

The answer is still no. ;-)
There are complicated ways. See
https://github.com/chasberry/orgmode-accessories/blob/ravel-lang/ox-ravel.org
for one such. But for what you are doing ATTR_HTML is easiest.

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

Yes. Depending on what you want one of these:
* Add this to `org-export-before-parsing-hook', perhaps in setting up a
derived exporter.
* Or perhaps by using a local variable `eval' see
: (info "(emacs) Specifying File Variables")
* Or by executing a src-block that loads those files.

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.

No, it is a property name. (cadr src-block) is the plist.

Any could be made to work, but I'd use (a). Then
: (org-babel-parse-header-arguments
: (car (plist-get (cadr src-block) :attr_html)))
will give you
: ((:data-external-libs . "http://underscorejs.org/underscore-min.js")
: (:class . "list of classes"))

Well, I'd just try it and see.

This is what I use:
* Elisp: (elisp). The Emacs Lisp Reference Manual.
* Emacs Lisp Intro: (eintr). A simple introduction to Emacs Lisp programming.
and ample Googling, usually leading to StackOverflow, to get hints on
stuff I am fuzzy on. And I read docstrings over and over and ...

:-) I think what I meant was, looks like (org-export-read-attribute
:attr_html src-block) RETURNS a plist. But that doesn't seem to be quite
true, if I'm understanding properly what a plist is.
Instead it returns a list of this form:
(:code_attribs data-external-libs="https://cdnjs.cloudflare.com/ajax/
libs/jquery/3.1.1/jquery.js" data-other="other" :class some class list)
Access to the :properties only seems reliable through
(org-export-read-attribute :attr_html src_plock :propname), which returns
what should be an odd list of symbols (?) as a string. Again, it seems
somewhat mysterious to me.
UPDATE: despite the tentative solution seen below, I guess maybe the
#+ATTR_XXX attributes are not intended for iteration as I describe, but
instead each such attribute should have a well-specified function that the
exporter knows about. If I'm adding attributes -- and it turns out that
ox-reveal can interpret a :code_attribs attribute that I hadn't known about
-- then I feel like I should structure them in an expected way. I haven't
found documentation about the best practice here and would definitely
appreciate further pointers.

ah, ok, thank you. Someday I hope I really understand list objects and
how to transform them. I think part of the problem is that, unlike in some
other languages, programming effectively requires a proper understanding of
*what the objects are that you're manipulating*, and I'm just a bit too
stupid to learn this effectively on my own.
And then, if I want to transform this into:

It looks to me like `org-export-read-attribute' reliably returns a
plist when used with three args.

That isn't a plist. I don't believe that `org-export-read-attribute'
gave you that. Maybe you dropped some quotes? Do you have an ECM that
shows that behavior?

You lost me here. I don't know what `src_plock' contains, so I can't
really say whether what that returns makes sense or not.
