mathjax with slideous does not update formulae

[dimpase]

http://johnmacfarlane.net/pandoc/demo/example16d.html produced with

pandoc  -s --mathjax -i -t slideous SLIDES -o example16d.html

does not render the maths formula correctly even after reloads (true for stable and for the git versions of pandoc, I tried these locally). The following change in SLIDES source for the last page fixes this issue:

# Conclusion
<table>
    <script type="text/javascript">
        MathJax.Hub.Queue(["Typeset",MathJax.Hub]);
    </script>
</table>
- And the answer is...
- $f(x)=\sum_{n=0}^\infty\frac{f^{(n)}(a)}{n!}(x-a)^n$    

I suppose this has to do with MathJax treating the pages as dynamic, and this is known to need a call to MathJax.Hub.Queue(). So a proper fix would insert these calls -- it seems that one such call on the last page suffices --to render all the mathjax maths in the document correctly.

I've never noticed a problem with mathjax in slidy or revealjs. Can you confirm that this problem only affects slideous?

[dimpase]

Indeed, it is OK with revealjs and other http://johnmacfarlane.net/pandoc/demo/example16[a-c].html, but not with
slideous (i.e. http://johnmacfarlane.net/pandoc/demo/example16d.html).

Just a proposal.

Since slideous replaces the body.html with its modified version of the original body.html, it would re-execute any javascript that may be within the scope of body.

Would you be able to just insert the following whenever slideous is chosen as an output? Perhaps inject within include-after?

<script type="text/javascript">
MathJax.Hub.Queue(["Typeset",MathJax.Hub]);
</script>

This would ensure that the typeset is forced right after slideous is finished processing.

Actually it should be easy enough to insert it directly in the

<script> tag as before, but only when slideous output is selected. +++ Alberto Leal [Oct 12 13 05:17 ]: > Just a proposal. > > Since slideous replaces the `body.html` with its modified version of the original `body.html`, it would re-execute any javascript that may be within the scope of `body`. > > Would you be able to just insert the following whenever slideous is chosen as an output?
