Hey everyone,
I'm trying to use Dov Grobgeld's org-slidy
(https://github.com/dov/org-slidy [1]) to create HTML-based slideshows
using org-mode, but it doesn't seem to be working. I'm not sure, but I
suspect this is because the syntax for org's HTML export may have
changed?
Attached is a quick hack --- ox-slidy.el, an org 8 exporter which
inherits from ox-s5.
It has a lot of stuff hardcoded that should be variables, but it works.
