ConTeXt: Math: \mframed in display mode

[Tobias Burnus]

Hi,

If I'm not completely mistaken then is there an difference between

$$
\mframed{\frac{a}{b} = c}
$$

and

$$
\frac{a}{b} = c
$$

It looks as if the former is printed in textstyle.

There is. We were at Dante, so this reply is a little late.
inserting \displaystyle yourself works OK, of course. 

For Hans: You need to remove the \restoremathstyle from \normalstrut
redef to get this to work OK.

How about this patch (core-rul.tex): 

\def\domframed[#1][#2]#3%
  {\begingroup
   \ifmmode
     \ifinner
       \let\mframedstyle\restoremathstyle
     \else
       \let\mframedstyle\displaystyle
     \fi
   \else
     \let\mframedstyle\restoremathstyle
   \fi
   #1\ifdone
     \def\normalstrut{$\mframedstyle\vphantom($}%
     \framed
       [\c!kaderoffset=\@@oioffset,\c!offset=\v!overlay,#2]
       {$\mframedstyle#3$}%
   \else
     \inframed
       [#2]
       {$\mframedstyle#3$}%
   \fi
   \endgroup}

The next ones go ok then. 

$\mframed{\frac{a}{b} = c}$

$$\mframed{\frac{a}{b} = c}$$

$$\mframed{\displaystyle \frac{a}{b} = c}$$

$$\frac{a}{b} = c$$

For those unaware of \mframed, I added this one for Tobias some time
ago. It is present in the latest contexts. The complication in these
macro(s) lays in trying to find out the right math modes/styles.
