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

Sadly it still didn't work on my machine. So what is different on your machine compared to mine? (Do you perhaps have a developing environment which automatically finds the proper TeX parts?) I just copied and pasted your example. The rendered results are seen in the attached screenshot. I'm not sure that attachments get through to you, but if you can view it, you can see that the formulae are rendered, just the cases command is not executed. I'm still using a SKIN from 1.9. on XWiki Enterprise 2.0.3.24848, running on postgres but I believe that should be irrelevant. Here's my code: ================START XWIKI CODE ================================== === 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} \\ 1 - x^2 & \mbox{otherwise\par}\end{cases} {{/formula}} Example from Sergiu {{formula}} f(x) = \begin{cases} 1 & -1 \le x \le 0 \\ \frac{1}{2} & x = 0 \\ 1 - x^2 & \mbox{otherwise} \end{cases} {{/formula}} Case definitions Used when a definition has two or more cases. Use the case statement. Notice that the spaces after the instances of if were included inside the mbox declarations. {{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}} Third try {{formula fontSize="normal"}}f(n) = \left\{ \begin{array}{l l} n/2 & \quad \text{if $n$ is even}\\ -(n+1)/2 & \quad \text{if $n$ is odd}\\ \end{array} \right.{{/formula}} ======================END XWIKI CODE================== Cheers, Steven Calkins E-Mail: steven.calkins(at)crossmediasolutions.de (in the event you want to see my image and can't) -----Ursprüngliche Nachricht----- Von: users-bounces(a)xwiki.org [mailto:users-bounces@xwiki.org] Im Auftrag von Sergiu Dumitriu Gesendet: Freitag, 13.

Then I restarted Xwiki but it didn't work. It still rendered the formula in a single line. Then I tried "the line "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. 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}} 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. My fault, I forgot to add this setting in the template that generates xwiki.cfg. 2.0 with the \mbox{-1 \le x< \mbox{if } the amsmath the default paragraph on http://code.xwiki.org/xwiki/bin/view/Macros/FormulaMacro#HTechnicalinf -- Sergiu Dumitriu http://purl.org/net/sergiu/ _______________________________________________ users mailing list users(a)xwiki.org http://lists.xwiki.org/mailman/listinfo/users
