In order for this to work properly, -% mutually exclusive options should be specified with -% \cs{DeclareExclusiveOptions}, another command defined by the -% \pkg{ifoption} package. -% \StopEventually{} -% -% \section{Implementation} -% \subsection{Package info} -% -% Standard declaration of package name and date. -% \begin{macrocode} -\NeedsTeXFormat{LaTeX2e} -\ProvidesPackage{ifoption}[2002/03/04 v1.02] -% \end{macrocode} -% -% \subsection{Some utility functions} -% -% \begin{macrocode} -\let\@xp\expandafter \let\@nx\noexpand -% \end{macrocode} -% -% \begin{macrocode} -\def\@True{00} -\def\@False{01} -% \end{macrocode} -% -% \subsection{Background} -% See the definitions of \cs{@onefilewithoptions} and -% \cs{@pushfilename} in the \lat/ kernel. -% -% When we have -%\begin{verbatim} -%\DeclareOption{foo}{some code} -%\end{verbatim} -% in a file named \fn{bar.sty}, \lat/ defines \cs{ds@foo} to contain -% \emph{some code}. Then if the package is invoked with -%\begin{verbatim} -%\usepackage[foo]{bar} -%\end{verbatim} -% there are two consequences: \opt{foo} is added to the options list -% for package \pkg{bar}, which is the control sequence -% \cs{opt@bar.sty}; and when \cs{ProcessOptions} is called, it -% executes \cs{ds@option-name} for each option found in the list. -% When it is finished running the options, \cs{ProcessOptions} -% undefines all the \cs{ds@whatever} for the current package, which -% are listed in the control sequence \cs{@declaredoptions}. At the -% end of \fn{bar.sty}, \cs{@declaredoptions} is globally reset to -% empty. Thus subordinate packages with options cannot be loaded in -% the \qq{first half} of a package that also has options, where first half -% means the area leading up to the \cs{ProcessOptions} call. -% -% For mutually exclusive options \xt{a}, \xt{b}, \xt{c}, when option -% \xt{b} is invoked it should remove all of its sibling options from -% the options-actually-used list and add itself to the list. For this -% task we make use of the fact that \cs{ProcessOptions} ends by -% undefining all the declared options of the current package or -% documentclass. -% -% \begin{macrocode} -\def\CurrentPackage{\@currname} -\let\CurrentClass\CurrentPackage -% \end{macrocode} -% -% \begin{macrocode} -\newcommand{\IfOption}{} -\def\IfPackageOption{\@ifpackagewith} -\def\IfClassOption{\@ifclasswith} -\def\IfOption{% - \ifx\@currext\@pkgextension \@xp\IfPackageOption - \else \@xp\IfClassOption - \fi - \@currname -} -% \end{macrocode} -% -% \begin{macrocode} -\newcommand{\DeclareExclusiveOptions}[1]{% - \xdef\@declaredoptions{\@declaredoptions,#1}% - \gdef\ProcessExclusiveOptions{\relax}% - \@for\CurrOption:=#1\do{% - \@xp\deo@a\csname ds@\CurrOption\@xp\endcsname\@xp{\CurrOption}{#1}% - }% -} -\def\DeclareBooleanOption{\DeclareExclusiveOptions} -% \end{macrocode} -% -% \begin{macrocode} -\def\deo@a#1#2#3{% - \def#1{% - \g@addto@macro\ProcessExclusiveOptions{\OptionsFalseTrue{#3}{#2}}% - }% -} -% \end{macrocode} -% -% \begin{macrocode} -\def\cull@options#1,{% - \@xp\ifx\csname ds@#1\@gobble\@percentchar\@empty\endcsname\@False - \else #1,\fi - \cull@options -} - -\newcommand{\OptionsFalseTrue}[2]{% - \begingroup - \@for\CurrentOption:=#1\do{% - \@xp\let\csname ds@\CurrentOption\endcsname\@False - }% - \let\ds@\@False - \@xp\xdef\csname opt@\@currname.\@currext\endcsname{% - \@xp\@xp\@xp\cull@options\csname opt@\@currname.\@currext\endcsname -% \end{macrocode} -% Lacking \cs{@secondofthree} and not keen on defining it \ldots -% \begin{macrocode} - ,\@firstoftwo\@firstoftwo,#2% - }% - \endgroup -} -% \end{macrocode} -% -% The usual \cs{endinput} to ensure that random garbage at the end of -% the file doesn't get copied by \fn{docstrip}. -% \begin{macrocode} -\endinput -% \end{macrocode} -% -% \CheckSum{112} -% \Finale |
