% \subsection{Initialization}
|
||||||
|
% These variable have to appear before the Lua module is loaded and will be used to
|
||||||
|
% communicate information to the callback.
|
||||||
|
%
|
||||||
|
% Here \cs{tracingmathml} does not use a expl3 name since it is not intended for
|
||||||
|
% programming use but only as a debugging helper for the user.
|
||||||
|
% The other variables are internal, but we provide public interfaces for setting
|
||||||
|
% them later.

%
|

% Now we can load the Lua module which defines the callback.

|
% \begin{macrocode}
|

|
\lua_now:n { require'luamml-tex' }
|
||||||
|
% \end{macrocode}
|
||||||
|
%
|
||||||
|
% \subsection{Flags}
|
||||||
|
% The most important interface is for setting the flag which controls how the
|
||||||
|
% formulas should be converted.
|
||||||
|
%
|
||||||
|
% \begin{macro}{\luamml_flag_process:}
|
||||||
|
% Consider the current formula to be a complete, free-standing mathematical
|
||||||
|
% expression which should be converted to MathML. Additionally, the formula
|
||||||
|
% is also saved in the \texttt{start\_math} node as with
|
||||||
|
% \cs{luamml_flag_save:}.
|
||||||
|
% \begin{macrocode}
|
||||||
|
\cs_new:Npn \luamml_flag_process: {
|
||||||
|
\int_set:Nn \l__luamml_flag_int { 3 }
|
||||||
|
}
|
||||||
|
% \end{macrocode}
|
||||||
|
% \end{macro}
|
||||||
|
%
|
||||||
|
% \begin{macro}{\luamml_flag_save:,
|
||||||
|
% \luamml_flag_save:N,
|
||||||
|
% \luamml_flag_save:n,
|
||||||
|
% \luamml_flag_save:Nn}
|
||||||
|
% Convert the current formula but only save it's representation in the math
|
||||||
|
% node without emitting it as a complete formula. This is useful when the
|
||||||
|
% expression forms part of a bigger formula and will be intergrated into it's
|
||||||
|
% MathML tables later by special code.
|
||||||
|
% It optinally accepts two parameters: One math style command
|
||||||
|
% (\cs{displaystyle}, \cs{textstyle}, etc.) which is the implicit math style
|
||||||
|
% (so the style which the surrounding code expects this style to have) and a
|
||||||
|
% name for the root element (defaults to \texttt{mrow}).
|
||||||
|
% If the root element name is \texttt{mrow}, it will get suppressed in some
|
||||||
|
% cases.
|
||||||
|
% \begin{macrocode}

% \begin{macro}{\luamml_flag_ignore:}
|
||||||
|
% Completely ignore the math mode material.
|
||||||
|
% \begin{macrocode}
|
||||||
|
\cs_new:Npn \luamml_flag_ignore: {

|
% \end{macro}
|
||||||
|
%
|
||||||
|
% \begin{macro}{\luamml_flag_structelem:}
|
||||||
|
% Like \cs{luamml_flag_process:}, but additionally add PDF structure
|
||||||
|
% elements. This only works if \pkg{tagpdf} has been loaded \emph{before}
|
||||||
|
% \texttt{luamml}.
|
||||||
|
% \begin{macrocode}
|
||||||
|
\cs_new:Npn \luamml_flag_structelem: {
|
||||||
|
\int_set:Nn \l__luamml_flag_int { 11 }

|
% \end{macro}
|
||||||
|
%
|
||||||
|
% \begin{macro}{\luamml_set_filename:n}
|
||||||
|
% Allows to set a filename to which the generated MathML gets written.
|
||||||
|
% Previous content from the file will get overwritten. This includes results
|
||||||
|
% written by a previous formula. Therefore this has to be called separately
|
||||||
|
% for every formula or it must expand to different values to be useful.
|
||||||
|
% The value is fully expanded when the file is written.
|
||||||
|
%
|
||||||
|
% Only complete formulas get written into files (so formulas where
|
||||||
|
% \cs{luamml_flag_process:} or \cs{luamml_flag_structelem:} are in effect).
|
||||||
|
% \begin{macrocode}
|
||||||
|
\cs_new:Npn \luamml_set_filename:n {
|
||||||
|
\tl_set:Nn \l__luamml_filename_tl
|
||||||
|
}
|
||||||
|
% \end{macrocode}
|
||||||
|
% \end{macro}
|
||||||
|
%
|
||||||
|
% By default, the flag is set to assume complete formulas.
|
||||||
|
% \begin{macrocode}
|
||||||
|
\luamml_flag_process:
|
||||||
|
% \end{macrocode}
|
||||||
|
%
|
||||||
|
% \subsection{Annotations}
|
||||||
|
% \begin{macro}{\luamml_annotate:nen, \luamml_annotate:en}
|
||||||
|
% A simple annotation scheme: The first argument is the number of top level
|
||||||
|
% noads to be annotated, the second parameter the annotation and the third
|
||||||
|
% parameter the actual list of math tokens. The first argument can be omitted to
|
||||||
|
% let Lua\TeX detrmine the number itself.
|
||||||
|
%
|
||||||
|
% Passing the first parameter explicitly is useful for any annotations which
|
||||||
|
% should be compatible with fututre pdf\TeX versions of this functionality.
|
||||||
|
% \begin{macrocode}
|
||||||
|
\cs_new_protected:Npn \luamml_annotate:nen #1#2#3 {
|
||||||
|
\__luamml_annotate_begin:
|
||||||
|
#3
|
||||||
|
\__luamml_annotate_end:we \tex_numexpr:D #1 \scan_stop: {#2}
|
||||||
|
}
|
||||||
|
|
||||||
|
\cs_new_protected:Npn \luamml_annotate:en #1#2 {
|
||||||
|
\__luamml_annotate_begin:
|
||||||
|
#2
|
||||||
|
\__luamml_annotate_end:e {#1}

}

|
% \end{macrocode}
|
||||||
|
% \end{macro}
|
||||||
|
%
|
||||||
|
% \subsection{Patching}
|
||||||
|
% For some packages, we ship with patches to make them more compatible and to
|
||||||
|
% demonstrate how other code can be patched to work with \texttt{luamml}.
|
||||||
|
%
|
||||||
|
% These are either loaded directly if the packages are loaded or delayed using
|
||||||
|
% \LaTeX's hook system otherwise.
|
||||||
|
% \begin{macro}{\__luamml_patch_package:nn, \__luamml_patch_package:n}
|
||||||
|
% For this, we use two helpers: First a wrapper which runs arbitrary code either
|
||||||
|
% now (if the package is already loaded) or as soon as the package loads, second
|
||||||
|
% an application of the first one to load packages following \texttt{luamml}'s
|
||||||
|
% naming scheme for these patch packages.
|
||||||
|
% \begin{macrocode}
|
||||||
|
\cs_new:Npn \__luamml_patch_package:nn #1 #2 {
|
||||||
|
\@ifpackageloaded {#1} {#2} {
|
||||||
|
\hook_gput_code:nnn {package/after/#1} {luamml} {#2}
|
||||||
|
}
|
||||||
|
}
|
||||||
|
\cs_new:Npn \__luamml_patch_package:n #1 {
|
||||||
|
\__luamml_patch_package:nn {#1} {
|
||||||
|
\RequirePackage { luamml-patches-#1 }
|
||||||
|
}
|

}

\RequirePackage { luamml-patches-kernel }
