Dear Hans,

I just did some experiments with the new \setupformulaframed, which you added recently after a demand by Aditya. However it seems to me that it does not do exactly what one might expect, at least in the example below.

Would it be possible to have a mechanism which gives somehow what Aditya was asking?

well, afaik he was asking for framed formulas but it will probably take a bit of time to test it with all kind of interferences

% begin framed-frormula.tex \setupformulaframed[framecolor=red,frame=on,offset=1ex] \setupformula[option=frame,color=blue]

\starttext

\startplaceformula \startformula f(x) := \left\{ \startalign \NC = -1\NC\quad \mbox{if }\, x < 0 \NR \NC = +1\NC\quad \mbox{if }\, x > 0 \NR \stopalign\right. \stopformula \stopplaceformula

\stoptext % end framed-frormula.tex

it's not related to framing ... you can put this in cont-new.mkiv after the \unprotect command there \def\math_halign_checked {\halign \ifnum\c_strc_formulas_mode=\plustwo % currently there is no need for width juggling \else \ifcase\eqalignmode \or to \checkeddisplaywidth \fi \fi} \def\math_both_eqalign_no_normal#1#2% {\ifmmode \the\mathdisplayaligntweaks \vcenter\bgroup \let\math_finish_eqalign_no\egroup \else \let\math_finish_eqalign_no\relax \fi #1% \math_halign_checked\expandafter\bgroup\the\scratchtoks\crcr#2\crcr\egroup \math_finish_eqalign_no} \def\math_both_eqalign_no_aligned#1% {\ifmmode \the\mathdisplayaligntweaks \global\mathnumberstatus\plusone \ifcase\mathraggedstatus \def\math_finish_eqalign_no{\crcr\egroup}% \else % we're in a mathbox \vcenter\bgroup \def\math_finish_eqalign_no{\crcr\egroup\egroup}% \fi \fi #1% \math_halign_checked\expandafter\bgroup\the\scratchtoks\crcr} ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
