Instiki users - Sep 2006 - [Instiki] problem with jsmath on $2^4=4^2$.

Hi,

I''m having troubles writing exponents using instiki and jsmath. Even a 
simple equation like $2^4=4^2$ produces something wrong where the
''4=4''
part gets raised and the second ''2'' is lowered. The HTML that
is
produced does indeed say: <p>$2<sup>4=4</sup>2$</p>.
All other more complicated LaTeX instruction work fine, so it seems 
something specific to the $x^y$ code and how it apparently gets confused 
for the ^superscript^ command in plain text.

Any pointers how I can avoid this problem?
Thanks,

Wim

Wim,

What''s happening is that Textile (or rather, RedCloth) is parsing the
math before jsmath gets a chance to do it''s thing. I use Markdown,
which has backslash escapes. So, for example, if I want:

$rb_k + b_e > c$

I need

$rb\_k + b\_e > c$

instead. Markdown will take out the backslashes, leaving the original
equation for jsmath to parse. I''m not sure how to escape properly in
Textile. While there''s a <notextile> tag, it converts things like
carats and equal signs into HTML entities, so it''s no-go for jsmath.
