Math without $$ doesn't show up when converted to slides

[ketch]

The IPython notebook now (wonderfully) recognizes latex that is delimited by, say \begin{align} and no dollar signs. But if converted to slides, any math without dollars around it is lost.

How are you converting to slides? Are you referring to the Javascript slideshow mode or using nbconvert? The former works fine for me, I have not tested the latter. I suspect this is a simple fix in terms of moving the appropriate MathJaX configuration over.

I'm just doing

ipython nbconvert --to='slides' *.ipynb --post serve

Is there a better way?

Are you seeing the same behaviour when you comvert to html, or just with the conversion to slides?

[ketch]

I see the same thing when I convert to html. I see this problem in Chrome, Safari, and Firefox.

I think this may be a pandoc issue. I seem to recall something similar that @ahmadia and I dealt with once in the past (when working with Gitit).

I will try investigate further... thank for report this...

[ahmadia]

I'm not sure if pandoc is being called with --parse-raw, but it may fix
this issue.

I fear even the --parse-raw will not be enough here as pandoc strips raw latex when converting to html (http://johnmacfarlane.net/pandoc/README.html#raw-tex). We are currenlty working on a similar issue here #3503 when converting to latex. Maybe something similar could be added here?

I just discovered, the easiest way to get your tex math (align) working is to embed it in $s. This way it gets "masked" and is not stripped by pandoc.
In a markdown cell:

$\begin{align}
1 & 2\\
4 & 3
\end{align}$

\begin{align}
a & b\\
d & c
\end{align}

works fine in notebook but after conversion the first works fine whereas the second align ins stripped

[ahmadia]

That's a workaround, but I think we'd all prefer if the mathjax gets passed
straight through. It looks like this will require either a patch or a
pandoc plugin.

@jakobgager That's just what the title of the issue says.

True 😜

This should be fixed now that we use marked for md2html
