This is supported by \AmS\LaTeX's \cs{underset} +% macro that works on both relational and binary symbols. A combination +% of \cs{underset} and \cs{overset} can be used to put \mbox{sub-} and +% superscripts to the same symbol. +% +% This package \xpackage{stackrel} extends the syntax of \cs{stackrel} +% by adding an optional argument for the subscript position. +% It follows the syntax of extensible arrows of packages +% \xpackage{amsmath} and \xpackage{mathtools}. +% +% \begin{declcs}{stackrel} +% |[|\meta{subscript}|]| \M{superscript} \M{rel}\\ +% \cs{stackbin} +% |[|\meta{subscript}|]| \M{superscript} \M{bin} +% \end{declcs} +% Example: +% \begin{quote} +% |A \stackbin[\text{and}]{}{+} B \stackrel[x]{!}{=} C|\\ +% $A \stackbin[\text{and}]{}{+} B \stackrel[x]{!}{=} C$ +% \end{quote} +% +% \StopEventually{ +% } +% +% \section{Implementation} +% +% \begin{macrocode} +%<*package> +\NeedsTeXFormat{LaTeX2e} +\ProvidesPackage{stackrel} + [2016/05/16 v1.3 Adding subscript option to stackrel (HO)]% +% \end{macrocode} +% +% Given the original definition of \cs{stackrel} the addition +% of the optional argument is straightforward. If an argument +% is empty, then the corresponding sub- or superscript is +% suppressed. +% +% Depending on the available resources (\eTeX, \pdfTeX) +% three methods are given for testing emptyness. All tests +% allow the hash to be used inside the arguments without +% doubling (for the unlikely case that someone wants to +% define macros with arguments). +% \begin{macro}{\stack@relbin} +% \begin{macrocode} +\RequirePackage{etexcmds}[2007/09/09] +\ifetex@unexpanded + \RequirePackage{pdftexcmds}[2016/05/16]% + \begingroup\expandafter\expandafter\expandafter\endgroup + \expandafter\ifx\csname pdf@strcmp\endcsname\relax + \newcommand*{\stack@relbin}[3][]{% + \mathop{#3}\limits + \edef\reserved@a{\etex@unexpanded{#1}}% + \ifx\reserved@a\@empty\else_{#1}\fi + \edef\reserved@a{\etex@unexpanded{#2}}% + \ifx\reserved@a\@empty\else^{#2}\fi + \egroup + }% + \else + \newcommand*{\stack@relbin}[3][]{% + \mathop{#3}\limits + \ifcase\pdf@strcmp{\detokenize{#1}}{}\else_{#1}\fi + \ifcase\pdf@strcmp{\detokenize{#2}}{}\else^{#2}\fi + \egroup + }% + \fi +\else + \newcommand*{\stack@relbin}[3][]{% + \mathop{#3}\limits + \toks@{#1}% + \edef\reserved@a{\the\toks@}% + \ifx\reserved@a\@empty\else_{#1}\fi + \toks@{#2}% + \edef\reserved@a{\the\toks@}% + \ifx\reserved@a\@empty\else^{#2}\fi + \egroup + }% +\fi +% \end{macrocode} +% \end{macro} +% \begin{macro}{\stackrel} +% \begin{macrocode} +\renewcommand*{\stackrel}{% + \mathrel\bgroup\stack@relbin +} +% \end{macrocode} +% \end{macro} +% \begin{macro}{\stackbin} +% \begin{macrocode} +\newcommand*{\stackbin}{% + \mathbin\bgroup\stack@relbin +} +% \end{macrocode} +% \end{macro} +% +% \begin{macrocode} +%</package> +% \end{macrocode} +% +% \section{Installation} +% +% \subsection{Download} +% +% \paragraph{Package.} This package is available on +% CTAN\footnote{\url{http://ctan.org/pkg/stackrel}}: +% \begin{description} +% \item[\CTAN{macros/latex/contrib/oberdiek/stackrel.dtx}] The source file. +% \item[\CTAN{macros/latex/contrib/oberdiek/stackrel.pdf}] Documentation. +% \end{description} +% +% +% \paragraph{Bundle.} All the packages of the bundle `oberdiek' +% are also available in a TDS compliant ZIP archive.

The files and directories obey the TDS standard. +% \begin{description} +% \item[\CTAN{install/macros/latex/contrib/oberdiek.tds.zip}] +% \end{description} +% \emph{TDS} refers to the standard ``A Directory Structure +% for \TeX\ Files'' (\CTAN{tds/tds.pdf}). Directories +% with \xfile{texmf} in their name are usually organized this way. +% +% \subsection{Bundle installation} +% +% \paragraph{Unpacking.} Unpack the \xfile{oberdiek.tds.zip} in the +% TDS tree (also known as \xfile{texmf} tree) of your choice. +% Example (linux): +% \begin{quote} +% |unzip oberdiek.tds.zip -d ~/texmf| +% \end{quote} +% +% \paragraph{Script installation.} +% Check the directory \xfile{TDS:scripts/oberdiek/} for +% scripts that need further installation steps. +% Package \xpackage{attachfile2} comes with the Perl script +% \xfile{pdfatfi.pl} that should be installed in such a way +% that it can be called as \texttt{pdfatfi}. +% Example (linux): +% \begin{quote} +% |chmod +x scripts/oberdiek/pdfatfi.pl|\\ +% |cp scripts/oberdiek/pdfatfi.pl /usr/local/bin/| +% \end{quote} +% +% \subsection{Package installation} +% +% \paragraph{Unpacking.} The \xfile{.dtx} file is a self-extracting +% \docstrip\ archive. The files are extracted by running the +% \xfile{.dtx} through \plainTeX: +% \begin{quote} +% \verb|tex stackrel.dtx| +% \end{quote} +% +% \paragraph{TDS.} Now the different files must be moved into +% the different directories in your installation TDS tree +% (also known as \xfile{texmf} tree): +% \begin{quote} +% \def\t{^^A +% \begin{tabular}{@{}>{\ttfamily}l@{ $\rightarrow$ }>{\ttfamily}l@{}} +% stackrel.sty & tex/latex/oberdiek/stackrel.sty\\ +% stackrel.pdf & doc/latex/oberdiek/stackrel.pdf\\ +% stackrel.dtx & source/latex/oberdiek/stackrel.dtx\\ +% \end{tabular}^^A +% }^^A +% \sbox0{\t}^^A +% \ifdim\wd0>\linewidth +% \begingroup +% \advance\linewidth by\leftmargin +% \advance\linewidth by\rightmargin +% \edef\x{\endgroup +% \def\noexpand\lw{\the\linewidth}^^A +% }\x +% \def\lwbox{^^A +% \leavevmode +% \hbox to \linewidth{^^A +% \kern-\leftmargin\relax +% \hss +% \usebox0 +% \hss +% \kern-\rightmargin\relax +% }^^A +% }^^A +% \ifdim\wd0>\lw +% \sbox0{\small\t}^^A +% \ifdim\wd0>\linewidth +% \ifdim\wd0>\lw +% \sbox0{\footnotesize\t}^^A +% \ifdim\wd0>\linewidth +% \ifdim\wd0>\lw +% \sbox0{\scriptsize\t}^^A +% \ifdim\wd0>\linewidth +% \ifdim\wd0>\lw +% \sbox0{\tiny\t}^^A +% \ifdim\wd0>\linewidth +% \lwbox +% \else +% \usebox0 +% \fi +% \else +% \lwbox +% \fi +% \else +% \usebox0 +% \fi +% \else +% \lwbox +% \fi +% \else +% \usebox0 +% \fi +% \else +% \lwbox +% \fi +% \else +% \usebox0 +% \fi +% \else +% \lwbox +% \fi +% \else +% \usebox0 +% \fi +% \end{quote} +% If you have a \xfile{docstrip.cfg} that configures and enables \docstrip's +% TDS installing feature, then some files can already be in the right +% place, see the documentation of \docstrip. +% +% \subsection{Refresh file name databases} +% +% If your \TeX~distribution +% (\teTeX, \mikTeX, \dots) relies on file name databases, you must refresh +% these. For example, \teTeX\ users run \verb|texhash| or +% \verb|mktexlsr|. +% +% \subsection{Some details for the interested} +% +% \paragraph{Attached source.} +% +% The PDF documentation on CTAN also includes the +% \xfile{.dtx} source file. It can be extracted by +% AcrobatReader 6 or higher. Another option is \textsf{pdftk}, +% e.g. unpack the file into the current directory: +% \begin{quote} +% \verb|pdftk stackrel.pdf unpack_files output .| +% \end{quote} +% +% \paragraph{Unpacking with \LaTeX.} +% The \xfile{.dtx} chooses its action depending on the format: +% \begin{description} +% \item[\plainTeX:] Run \docstrip\ and extract the files. +% \item[\LaTeX:] Generate the documentation. +% \end{description} +% If you insist on using \LaTeX\ for \docstrip\ (really, +% \docstrip\ does not need \LaTeX), then inform the autodetect routine +% about your intention: +% \begin{quote} +% \verb|latex \let\install=y\input{stackrel.dtx}| +% \end{quote} +% Do not forget to quote the argument according to the demands +% of your shell. +% +% \paragraph{Generating the documentation.} +% You can use both the \xfile{.dtx} or the \xfile{.drv} to generate +% the documentation. The process can be configured by the +% configuration file \xfile{ltxdoc.cfg}. For instance, put this +% line into this file, if you want to have A4 as paper format: +% \begin{quote} +% \verb|\PassOptionsToClass{a4paper}{article}| +% \end{quote} +% An example follows how to generate the +% documentation with pdf\LaTeX: +% \begin{quote} +%\begin{verbatim} +%pdflatex stackrel.dtx +%makeindex -s gind.ist stackrel.idx +%pdflatex stackrel.dtx +%makeindex -s gind.ist stackrel.idx +%pdflatex stackrel.dtx +%\end{verbatim} +% \end{quote} +% +% \section{Catalogue} +% +% The following XML file can be used as source for the +% \href{http://mirror.ctan.org/help/Catalogue/catalogue.html}{\TeX\ Catalogue}. +% The elements \texttt{caption} and \texttt{description} are imported +% from the original XML file from the Catalogue. +% The name of the XML file in the Catalogue is \xfile{stackrel.xml}. +% \begin{macrocode} +%<*catalogue> +<?xml version='1.0' encoding='us-ascii'?> +<!DOCTYPE entry SYSTEM 'catalogue.dtd'> +<entry datestamp='$Date$' modifier='$Author$' id='stackrel'> + <name>stackrel</name> + <caption>Enhancement to the \stackrel command.</caption> + <authorref id='auth:oberdiek'/> + <copyright owner='Heiko Oberdiek' year='2006,2007'/> + <license type='lppl1.3'/> + <version number='1.3'/> + <description> + This package adds an optional argument to <tt>\stackrel</tt> for + putting something below the relational symbol and defines + <tt>\stackbin</tt> for binary symbols. + <p/> + The package is part of the <xref refid='oberdiek'>oberdiek</xref> + bundle. + </description> + <documentation details='Package documentation' + href='ctan:/macros/latex/contrib/oberdiek/stackrel.pdf'/> + <ctan file='true' path='/macros/latex/contrib/oberdiek/stackrel.dtx'/> + <miktex location='oberdiek'/> + <texlive location='oberdiek'/> + <install path='/macros/latex/contrib/oberdiek/oberdiek.tds.zip'/> +</entry> +%</catalogue> +% \end{macrocode} +% +% \begin{History} +% \begin{Version}{2006/12/02 v1.0} +% \item +% First version. +% \end{Version} +% \begin{Version}{2007/05/06 v1.1} +% \item +% Uses package \xpackage{etexcmds}. +% \end{Version} +% \begin{Version}{2007/11/11 v1.2} +% \item +% Use of package \xpackage{pdftexcmds} for \LuaTeX\ support. +% \end{Version} +% \begin{Version}{2016/05/16 v1.3} +% \item +% Documentation updates. +% \end{Version} +% \end{History} +% +% \clearpage +% \PrintIndex +% +% \Finale +\endinput |
