[xwiki-users] Latex {cases} command doesn't work in default xwiki 2.0 formula macro
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

The cases environment is not standard TeX, it belongs to the amsmath package. This means that it is not supposed to work using the default backend. It should work with the native one, which uses the amsmath package, and you could try using the mathtran one. If you decide to change the backend, you'll find instructions in the last paragraph on http://code.xwiki.org/xwiki/bin/view/Macros/FormulaMacro#HTechnicalinformati... -- Sergiu Dumitriu http://purl.org/net/sergiu/
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.

Oh yes, and "snuggletex" doesn't work either. Steven Calkins -----Ursprüngliche Nachricht----- Von: [email protected] [mailto:[email protected]] Im Auftrag von Steven Calkins Gesendet: Freitag, 13.

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}}
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.

My fault, I forgot to add this setting in the template that generates xwiki.cfg.
