I am trying to define bold math myself, but encounter a problem with the typescripts.
As always, when desperately posting the problem, something suggests itself that brings a solution of some sort. I looked into the definition of \bfmath, traced its execution and found out that afterall my own [bfmath] typescript was indeed used! But in order to get the same behaviour between normal math (variables set in MathItalic) and bold math I had to change the definition of \bfmath: \def\bfmath{\bf\mf\synchronizesymb\mi} That is, the last font switch made to \mi instead of \mf as is done font-ini.tex. Then I see the same behaviour in math and bfmath, that is MathItalic with $etc$ and MathItalicBold with $\bfmath etc$. My question to Hans Hagen: Should this change be followed in font- ini.tex? Personally, I feel confused by having math and bold math behaving differently. Hans van der Meer
Further probing into this matter (previous mail, see below) shows that the typescript delineated by ****'s is NOT USED AT ALL! (Calling \setupformulas[method=bold] makes no difference). It therefore does not seem a problem in the math family assignments in font-bfm.tex, as I first suspected.
Is there some special invocation needed for hooking up a user defined font set into $\bfmath ...$? If have looked into font-bfm.tex and font-ini.tex but could not figure it out. Clearly I am misunderstanding the inner workings here, but I have no clue in which direction to look.
I am using the follwing (extracted) typescript lines for math in the lucida fonts:
\starttypescript [luc] \definetypeface [luc][mm][math][lucidayy][default] [encoding=texnansi] \definetypeface [luc][mm][bfmath][lucidayy][default] [encoding=texnansi] \stoptypescript
\starttypescript [math] [lucidayy] [default] \definebodyfont [default] [mm] [mr=MathRoman mo 1, mi=MathItalic mo 1, ....] \stoptypescript
********************************************************************** ********
\starttypescript [bfmath] [lucidayy] [default] \definebodyfont [default] [mm] [mrbf=MathRomanBold mo 1, mibf=MathItalicBold mo 1, ....] \stoptypescript
********
\starttypescript [math] [lucidayy] [name] \definefontsynonym [MathRoman] [LucidaBright] \definefontsynonym [MathItalic] [LucidaNewMath-AltItalic] \stoptypescript
\starttypescript [math] [lucidayy] [texnansi,ec,8r] \definefontsynonym [LucidaBright] [hlhr8y] [encoding=texnansi] \definefontsynonym [LucidaNewMath-AltItalic] [hlcrima] \stoptypescript
\starttypescript [bfmath] [lucidayy] [name] \definefontsynonym [MathRomanBold] [LucidaBright-Demi] \definefontsynonym [MathItalicBold] [LucidaNewMath- AltDemiItalic] \stoptypescript
\starttypescript [bfmath] [lucidayy] [texnansi,ec,8r] \definefontsynonym [LucidaBright-Demi] [hlhb8y] [encoding=texnansi] \definefontsynonym [LucidaNewMath-AltDemiItalic] [hlcdima] \stoptypescript
Typesetting: \starttext \usetypescript[luc][texnansi]\setupbodyfont[luc,10pt]\lucidatrue {$\sqrt{a^2 + b^2} = c + \mf\sin{}x\quad {\ma NZRC}$}\crlf \stoptext Gives me for the variables neatly LucidaNewMath-AltItalic. *** Changing the fonts in the above typescript does work ***
But typesetting \starttext \usetypescript[luc][texnansi]\setupbodyfont[luc,10pt]\lucidatrue {$\bfmath\sqrt{a^2 + b^2} = c + \mf\sin{}x\quad {\ma NZRC}$}\crlf \stoptext Gives me LucidaBright-Demi instead of LucidaNewMath-AltDemiItalic. Everything else however (even the blackletters from ma) are in the correct bold math font. The font must be present, because substituting MathItalicBold for MathItalic in the [math] script proves that. *** But not coming from my typescript I conclude from several experiments ***
