[XeTeX] Suggestion for xelatex.ini (enlarging math families from 16 to 256)

[Vafa Khalighi]

Hi

Since XeTeX allows you to have 256 math families instead 16, I was
wondering if this could be done in xelatex.ini. The required changes are:

\def\new at mathgroup{\alloc at 8\mathgroup\chardef\@cclvi}
\let\newfam\new at mathgroup
\def\select at group#1#2#3#4{%
 \ifx\math at bgroup\bgroup\else\relax\expandafter\@firstofone\fi
 {%
 \ifmmode
  \ifnum\csname c at mv@\math at version\endcsname<\@cclvi
     \begingroup
       \escapechar\m at ne
       \getanddefine at fonts{\csname c at mv@\math at version\endcsname}#3%
       \globaldefs\@ne  \math at fonts
     \endgroup
     \init at restore@version
     \xdef#1{\noexpand\use at mathgroup\noexpand#2%
             {\number\csname c at mv@\math at version\endcsname}}%
     \global\advance\csname c at mv@\math at version\endcsname\@ne
   \else
     \let#1\relax
     \@latex at error{Too many math alphabets used in
                   version \math at version}%
        \@eha
   \fi
 \else \expandafter\non at alpherr\fi
 #1{#4}%
 }%
}
\def\document at select@group#1#2#3#4{%
 \ifx\math at bgroup\bgroup\else\relax\expandafter\@firstofone\fi
 {%
 \ifmmode
   \ifnum\csname c at mv@\math at version\endcsname<\@cclvi
     \begingroup
       \escapechar\m at ne
       \getanddefine at fonts{\csname c at mv@\math at version\endcsname}#3%
       \globaldefs\@ne  \math at fonts
     \endgroup
     \expandafter\extract at alph@from at version
         \csname mv@\math at version\expandafter\endcsname
         \expandafter{\number\csname
                       c at mv@\math at version\endcsname}%
          #1%
     \global\advance\csname c at mv@\math at version\endcsname\@ne
   \else
     \let#1\relax
     \@latex at error{Too many math alphabets used
                   in version \math at version}%
        \@eha
  \fi
 \else \expandafter\non at alpherr\fi
 #1{#4}%
 }%
}
