a post-processing export hook?

a post-processing export hook?

[John Kitchin]

Hi all,

I tried using org-export-before-parsing-hook to modify an org-file prior
to export to replace some regular expressions with html.

I ran into the following issue. For short substitutions,
@@html:replacement@@ worked fine. If the replacement text got too long,
this broke. I did wrap it in a #+begin_html: block, but that introduced
line breaks that were undesireable. The replacement text was long
because I had a large tool tip to put on some text.

I ended up doing a post-process like this:

(with-current-buffer (org-html-export-as-html)
  (org-process-key-bindings 'html)
  (org-process-emacs-commands 'html)
  (write-file "blog.html")
  (browse-url "blog.html"))

But, I wondered if there should be a post-export hook? I can see some
challenge for pdf export, for example. The hook should run after the
latex export, not after the pdf is made.

I could have used a filter on a paragraph, which is where most of the
things I was modifying were. Is there some other way I could have done
this?

I don't think your example warrant an extra hook.  Replacing strings is
something that org-export-filter-final-output-functions is perfectly
capable of doing IMO.  It’s a bit of a hassle to work with transcoded
strings, but having a hook would not change this.

True enough. I tried it with a paragraph filter and it worked fine. I
didn't know about the org-export-filter-final-output-functions, that is
pretty much the hook I was looking for. Thanks,

OK.  Now OP makes more sense.  All filters are listed in:

   org-export-filters-alist

The documentation is mostly in the source of ox.el.

Worg also has this:

http://orgmode.org/worg/doc.html

One cold and dreary evening I quickly browsed the list of hooks in
org-mode when I was curious about tangling hooks.

It is a pretty decent read and very educational; it gives you a
picture into the "eventspace" or org.
