Subject: sa-ignore-headline for HTML export
Date: Wed, 08 Jan 2014 09:29:25 +0800	[thread overview]
Message-ID: <655e7cf5-021a-413d-9485-5f7e48bb05ba@dewdrop-world.net> (raw)

Hi Suvayu,

I've been using your "sa-ignore-headline" filter [1] for a while -- works 
great for LaTeX.

(defun sa-ignore-headline (contents backend info)
  "Ignore headlines with tag `ignoreheading'."
  (when (and (org-export-derived-backend-p backend 'latex 'html 'ascii)
          (string-match "\\`.*ignoreheading.*\n"
                (downcase contents)))
    (replace-match "" nil nil contents)))

Unfortunately, although this is supposed to apply to latex, html and ascii 
backends, the string-match works only for LaTeX. I was just trying it with 
HTML and there was no effect.

For HTML export, the "contents" end up looking like this:

<div id="outline-container-sec-2" class="outline-2">
<h2 id="sec-2"><span class="section-number-2">2</span> 
B&#xa0;&#xa0;&#xa0;<span class="tag"><span 
class="ignoreheading">ignoreheading</span></span></h2>
<div class="outline-text-2" id="text-2">
<p>
Text B
</p>
</div>
</div>

.. where there is no backquote to match.

So I've changed the string-match predicate to read as follows (also 
removing the downcase), and it now works with HTML export.

(string-match ".*ignoreheading.*" contents)

That's a hack -- sufficient for now, but ideally I suppose it should 
dispatch to a different predicate per backend.

Posting here because I didn't see a way on stackexchange to comment on your 
answer.

Thanks for the function! It would have taken me ages to figure it out on my 
own.
