However, that is not quite the case, and -% some things that you'd expect to work don't (e.g., \verb|^\cong|) -% whereas others which you'd think shouldn't work actually -% do (such as |^\mathsf{s}|). We do everyone a favor if it behaves -% consistently, i.e., if the superscript and subscript operations -% act as if they are macros taking exactly one argument. -% -% \item Because the \TeX\ math typesetting engine uses infix notation -% for fractions, one has to use \cs{mathchoice} or \cs{mathpalette} -% whenever trying to do anything requiring boxing or measuring -% math. This creates problems for loading fonts on demand as the -% font loading mechanism has to load fonts for all styles without -% even knowing if the font is going to be used. Getting the timing -% of \cs{mathchoice} right can be tricky as well. Since \LaTeX\ does -% not promote the primitive infix notation, this package keeps track -% of a current mathstyle parameter. -% \end{itemize} -% -% -% \section{Some usage tips} -% -% If you want to use this package with \pkg{amsmath}, it is important -% \pkg{mathstyle} is loaded \emph{after} \pkg{amsmath}. -% -% The current mathstyle is stored in the variable \cs{mathstyle}. The -% command \cs{currentmathstyle} can be used to switch to the mode -% currently active. Below is shown how the macro \cs{mathrlap} from -% \pkg{mathtools} is implemented without knowing about the current -% mathstyle using \cs{mathpalette}. -% \begin{verbatim} -% \providecommand*\mathrlap[1][]{% -% \ifx\@empty#1\@empty -% \expandafter \mathpalette \expandafter \@mathrlap -% \else -% \expandafter \@mathrlap \expandafter #1% -% \fi} -% \providecommand*\@mathrlap #1#2{{}\rlap{$\m@th#1{#2}$}} -% \end{verbatim} -% The same definition using \cs{currentmathstyle} from this package. -% \begin{verbatim} -% \providecommand*\mathrlap[2][]{% -% #1 {}\rlap{$\m@th \currentmathstyle {#2}$}} -% \end{verbatim} -% -% \subsection{Package options} -% -% This package has one set of options affecting the \verb|_| and \verb|^| characters: -% -% \begin{itemize} -% \item\verb|\usepackage[mathactivechars]{mathstyle}| -% -% This is the default behaviour. Here, \verb|_| and \verb|^| are made into harmless -% characters in text mode and behave as expected (for entering sub/superscript) when -% inside math mode. -% Certain code that assumes the catcodes of these characters may get confused about -% this; see below for a possible fix. -% -% \item\verb|\usepackage[activechars]{mathstyle}| -% -% With this option, \verb|_| and \verb|^| are made into active characters for -% entering sub/superscript mode in all cases---therefore, in text mode they will -% produce a regular error (`Missing \$ inserted') indicating they are being used -% out of place. -% -% \item\verb|\usepackage[noactivechars]{mathstyle}| -% -% This is the option most like to solve any compatibility problems. Here, -% \verb|_| and \verb|^| retain their regular catcodes at all times and behave -% in their default fashion. \textbf{However}, certain other features of this -% package (such as \cs{currentmathstyle} inside a subscript) will then fail -% to work, so only use this option as a last resort. -% \end{itemize} -% -% \StopEventually{} -% \part*{Implementation} -% -% \begin{macrocode} -%<*package> -% \end{macrocode} -% -% \begin{macro}{\@saveprimitive} -% A straight copy from \pkg{breqn}, see implementation details -% there.
