Dear all,
The LaTeX {case} macro doesn't seem to work in Xwiki 2.0 with
the default LaTeX renderer.
Try these two examples to reproduce it and compare with
http://en.wikipedia.org/wiki/Math_markup#Examples_2:
[XWIKI CODE STARTS HERE]
=== Continuation and cases===
This example from wikipedia doesn't seem to work:
{{formula fontSize="normal"}}f(x) = \begin{cases}1 & \mbox{-1 \le x <
0\par} \\
\frac{1}{2} \;\;\;& \mbox{x = 0\par} \\ 1 - x^2 &
\mbox{otherwise\par}\end{cases}{{/formula}}
===Case definitions===
{{formula fontSize="normal"}}f(n) = \begin{cases} n/2, & \mbox{if }
n\mbox{ is even} \\ 3n+1, & \mbox{if } n\mbox{ is odd}
\end{cases}{{/formula}}
[XWIKI CODE ENDS HERE]
Any suggestions?
Greetings,
Steven Calkins

Hi Sergiu,
I tried what you said, adding the line "macro.formula.renderer = native" to
WEB-INF/xwiki.properties and saving it. Then I restarted Xwiki but it didn't work. It
still rendered the formula in a single line. Then I tried "macro.formula.renderer =
mathtran", saved it, and restarted xwiki. It still didn't work. Is there some
part of the the TeX package still missing? I just installed XWiki Enterprise 2.0.3.24848,
it runs on postgres.
I was a little surprised that I had to add a line in the WEB-INF/xwiki.properties file and
not uncomment a line and change its value, as you do in most cases. Could it be that I
have an older config file or is the line in WEB-INF/xwiki.properties not available yet in
the newest version? I used the config from the download, and changed only those values
that pertained to my earlier system settings.
Greetings,
Steven Calkins

Oh yes, and "snuggletex" doesn't work either.

OK, it seems that the default renderer is the native one, so there was
no need to change it.
I tried your example, and actually there's a problem with the formula.
The code from your mail causes the native renderer to fail because
there's a syntax error, specifically the first mbox contains \le, which
is only valid in math mode. This works fine:
{{formula}}
f(x) =
\begin{cases}
1 & -1 \le x \le 0 \\
\frac{1}{2} & x = 0 \\
1 - x^2 & \mbox{otherwise}
\end{cases}
{{/formula}}
My fault, I forgot to add this setting in the template that generates
xwiki.cfg.
