Hi everybody, Does anyone have noticed that the mathalignment has changed its behaviour recently? I think a bug has managed to enter the environment which handles the mathalignment, at least since a few weeks ago. I did not report it earlier because I was traveling and did not have a stable internet access.
Here is a minimal example where on can see in the first displayed formula that
the first and third column are centered while the first one shoud be
right-aligned and the third one left-aligned. (Actually it seems that all
columns are centered…)
%%% begin pb-math-align.tex
\definemathmatrix[alignedcases]
[align={right,left,left},
distance=3pt,
left={\left\{},
right={\right.},
style=\displaystyle]
\starttext
\startformula
\startalignedcases
\NC \partial_{tt} u - \Delta u + q(x) u \NC = 0 \NC \quad\mbox{in
}\;(0,T)\times\Omega \NR
\NC u(0,x) \NC = 0 \NC \quad \mbox{in }\; \Omega \NR
\NC \partial_{t} u(0,x) \NC = 0 \NC \quad \mbox{in }\; \Omega \NR
\NC {\partial u \over\partial{\bf n} } \NC = g(t,\sigma) \NC \quad \mbox{on }\;
(0,T)\times\partial\Omega. \NR
