\begin{case} need \\\\ for line break instead of \\

[dinya]

I want to write cases (like here http://meta.math.stackexchange.com/a/5025) with

$  f(n) =
\begin{cases}
n/2,  & \text{if $n$ is even} \\
3n+1, & \text{if $n$ is odd}
\end{cases}
$

but for correct line break I must use \\\\ instead of \\.

Is it feature of plugin/platform or bug?

I use last plugin version from this repository.

It's the nature of having server side processing for markdown. I don't think modifying this behavior would be possible without modifying the code for Redmine directly (I don't know if plugins can change the behavior of markdown).

Today the plugin is a macro.

The advantage of the macro is that it bypassed the markup parser. So you have to update to the latest version and use it like

Sigleline expression

{{ mj( <single line expr.> ) }}

or in your case: Multiline:

{{ mj
f(n) =
\begin{cases}
n/2,  & \text{if $n$ is even} \\
3n+1, & \text{if $n$ is odd}
\end{cases}
}}

That's right, I forgot you had made that change. Closing this issue then.
