[IPython-dev] ipython html notebook: markdown in math mode and backslashes

I feel like a jerk, I just checked to see if this problem shows up on our
own gitit+pagedown live renderer, and the same bug is present!  We use
pandoc to do the final render, which is probably why I hadn't noticed it

The StackExchange guys do some special parsing before they hand their code
off to the PageDown parser, you can see it here:


This is probably going to be the most familiar syntax for people used to
LaTex and willing to work with Markdown for their outer formatting.

Digging into the ipython source, the Markdown.converter is initialized in
notebookmain.js then utilized in the textcell.js markdown render function.
 I don't see any special parsing done for handling the math symbols.   I
think the render function in textcell.js would be the right place to add
the math delimiter strip/replace hooks.

If you guys are interested, I can see about getting the SE
mathjax-editing-new.js code licensed for redistribution, the SE guys are
pretty hip to this kind of thing so I don't expect it to be a problem.
