For every letter (start with ascii a-zA-Z and numbers to keep things simple for now), they are assigned a `mathcode' with \cmd\Umathcode\ that maps from input letter to output font glyph slot. This is done with the equivalent of +% \begin{Verbatim} +% \Umathcode`\a = 7 1 "1D44E\relax +% \Umathcode`\b = 7 1 "1D44F\relax +% \Umathcode`\c = 7 1 "1D450\relax +% ... +% \end{Verbatim} +% When switching from regular letters to, say, \cmd\mathrm, we now need to execute a new mapping: +% \begin{Verbatim} +% \Umathcode`\a = 7 1 `\a\relax +% \Umathcode`\b = 7 1 `\b\relax +% \Umathcode`\c = 7 1 `\c\relax +% ... +% \end{Verbatim} +% This is fairly straightforward to perform when we're defining our own commands such as \cmd\symbf\ and so on. However, this means that `classical' \TeX\ font setups will break, because with the original mapping still in place, the engine will be attempting to insert unicode maths glyphs from a standard font. +% +% \subsection{Hooks into \LaTeXe} +% +% To overcome this, we patch \cs{use@mathgroup}. +% (An alternative is to patch \cs{extract@alph@from@version}, which constructs the \cs{mathXYZ} commands, but this method fails if the command has been defined using \cs{DeclareSymbolFontAlphabet}.) +% As far as I can tell, this is only used inside of commands such as \cs{mathXYZ}, so this shouldn't have any major side-effects. +% +% \begin{macrocode} +\cs_set:Npn \use@mathgroup #1 #2 + { + \mode_if_math:T % <- not sure if this is really necessary since we've just checked for mmode and raised an error if not! + { + \math@bgroup + \cs_if_eq:cNF {M@\f@encoding} #1 {#1} + \@@_switchto_literal: + \mathgroup #2 \relax + \math@egroup + } + } +% \end{macrocode} +% +% In LaTeX maths, the command |\operator@font| is defined that switches to the |operator| mathgroup. The classic example is the |\sin| in |$\sin{x}$|; essentially we're using |\mathrm| to typeset the upright symbols, but the syntax is |{\operator@font sin}|. +% I thought that hooking into |\operator@font| would be hard because all other maths font selection in 2e uses |\mathrm{...}| style. +% Then reading source2e a little more I stumbled upon: +% \begin{macro}{\operator@font} +% \begin{macrocode} +\cs_set:Npn \operator@font + { + \@@_switchto_literal: + \@fontswitch {} { \g_@@_operator_mathfont_tl } + } +% \end{macrocode} +% \end{macro} +% +% +% \subsection{Setting styles} +% +% Algorithm for setting alphabet fonts. +% By default, when |range| is empty, we are in \emph{implicit} mode. +% If |range| contains the name of the math alphabet, we are in \emph{explicit} +% mode and do things slightly differently. +% +% Implicit mode: +% \begin{itemize} +% \item Try and set all of the alphabet shapes. +% \item Check for the first glyph of each alphabet to detect if the font supports each +% alphabet shape. +% \item For alphabets that do exist, overwrite whatever's already there. +% \item For alphabets that are not supported, \emph{do nothing}. +% (This includes leaving the old alphabet definition in place.) +% \end{itemize} +% +% Explicit mode: +% \begin{itemize} +% \item Only set the alphabets specified. +% \item Check for the first glyph of the alphabet to detect if the font contains +% the alphabet shape in the Unicode math plane. +% \item For Unicode math alphabets, overwrite whatever's already there. +% \item Otherwise, use the \ascii\ glyph slots instead. +% \end{itemize} +% +% +% +% \subsection{Defining the math style macros} +% +% We call the different shapes that a math alphabet can be a `math style'. +% Note that different alphabets can exist within the same math style.
