Packages \xpackage{hyperref}, \xpackage{nameref}, +% \xpackage{titleref}, and \xpackage{babel} are supported. +% \end{abstract} +% +% \tableofcontents +% +% \section{Usage} +% +% \subsection{Setting counters} +% +% The following commands are similar to \LaTeX's +% \cs{setcounter} and \cs{addtocounter}, +% but they extract the number value from a reference: +% \begin{quote} +% \cs{setcounterref}, \cs{addtocounterref}\\ +% \cs{setcounterpageref}, \cs{addtocounterpageref} +% \end{quote} +% They take two arguments: +% \begin{quote} +% \cs{...counter...ref} |{|\meta{\LaTeX\ counter}|}| +% |{|\meta{reference}|}| +% \end{quote} +% An undefined references produces the usual LaTeX warning +% and its value is assumed to be zero. +% Example: +% \begin{quote} +%\begin{verbatim} +%\newcounter{ctrA} +%\newcounter{ctrB} +%\refstepcounter{ctrA}\label{ref:A} +%\setcounterref{ctrB}{ref:A} +%\addtocounterpageref{ctrB}{ref:A} +%\end{verbatim} +% \end{quote} +% +% \subsection{Expandable commands} +% +% These commands that can be used in expandible contexts +% (inside calculations, \cs{edef}, \cs{csname}, \cs{write}, \dots): +% \begin{quote} +% \cs{getrefnumber}, \cs{getpagerefnumber} +% \end{quote} +% They take one argument, the reference: +% \begin{quote} +% \cs{get...refnumber} |{|\meta{reference}|}| +% \end{quote} +% The default for undefined references can be changed +% with macro \cs{setrefcountdefault}, for example this +% package calls: +% \begin{quote} +% \cs{setrefcountdefault}|{0}| +% \end{quote} +% +% Since version 2.0 of this package there is a new +% command: +% \begin{quote} +% \cs{getrefbykeydefault} |{|\meta{reference}|}| +% |{|\meta{key}|}| |{|\meta{default}|}| +% \end{quote} +% This generalized version allows the extraction +% of further properties of a reference than the +% two standard ones. Thus the following properties +% are supported, if they are available: +% \begin{quote} +% \begin{tabular}{@{}l|l|l@{}} +% Key & Description & Package\\ +% \hline +% \meta{empty} & same as \cs{ref} & \LaTeX\\ +% |page| & same as \cs{pageref} & \LaTeX\\ +% |title| & section and caption titles & \xpackage{titleref}\\ +% |name| & section and caption titles & \xpackage{nameref}\\ +% |anchor| & anchor name & \xpackage{hyperref}\\ +% |url| & url/file & \xpackage{hyperref}/\xpackage{xr} +% \end{tabular} +% \end{quote} +% +% Since version 3.2 the expandable macros described before +% in this section +% are expandable in exact two expansion steps. +% +% \subsection{Undefined references} +% +% Because warnings and assignments cannot be used in +% expandible contexts, undefined references do not +% produce a warning, their values are assumed to be zero. +% Example: +% \begin{quote} +%\begin{verbatim} +%\label{ref:here}% somewhere +%\refused{ref:here}% see below +%\ifodd\getpagerefnumber{ref:here}% +% reference is on an odd page +%\else +% reference is on an even page +%\fi +%\end{verbatim} +% \end{quote} +% +% In case of undefined references the user usually want's +% to be informed. Also \LaTeX\ prints a warning at +% the end of the \LaTeX\ run. To notify \LaTeX\ and +% get a normal warning, just use +% \begin{quote} +% \cs{refused} |{|\meta{reference}|}| +% \end{quote} +% outside the expanding context. Example, see above. +% +% \subsubsection{Check for undefined references} +% +% In version 3.2 macros were added, that test, whether references +% are defined. +% \begin{declcs}{IfRefUndefinedExpandable} \M{refname} \M{then} \M{else}\\ +% \cs{IfRefUndefinedBabel} \M{refname} \M{then} \M{else} +% \end{declcs} +% If the reference is not available and therefore undefined, then +% argument \meta{then} is executed, otherwise argument \meta{else} +% is called. Macro \cs{IfRefUndefinedExpandable} is expandable, +% but \meta{refname} must not contain babel shorthand characters. +% Macro \cs{IfRefUndefinedBabel} supports shorthand characters of +% babel, but it is not expandable. +% +% \subsection{Notes} +% +% \begin{itemize} +% \item +% The method of extracting the number in this +% package also works in cases, where the +% reference cannot be used directly, because +% a package such as \xpackage{hyperref} has added +% extra stuff (hyper link), so that the reference cannot +% be used as number any more. +% \item +% If the reference does not contain a number, +% assignments to a counter will fail of course. +% \end{itemize} +% +% +% \StopEventually{ +% } +% +% \section{Implementation} +% +% \begin{macrocode} +%<*package> +%

\section{Installation} +% +% \subsection{Download} +% +% \paragraph{Package.} This package is available on +% CTAN\footnote{\CTANpkg{refcount}}: +% \begin{description} +% \item[\CTAN{macros/latex/contrib/refcount/refcount.dtx}] The source file. +% \item[\CTAN{macros/latex/contrib/refcount/refcount.pdf}] Documentation. +% \end{description} +% +% +% \paragraph{Bundle.} All the packages of the bundle `oberdiek' +% are also available in a TDS compliant ZIP archive. There +% the packages are already unpacked and the documentation files +% are generated. The files and directories obey the TDS standard. +% \begin{description} +% \item[\CTANinstall{install/macros/latex/contrib/refcount.tds.zip}] +% \end{description} +% \emph{TDS} refers to the standard ``A Directory Structure +% for \TeX\ Files'' (\CTANpkg{tds}). 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} +% +% \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 refcount.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@{}} +% refcount.sty & tex/latex/refcount/refcount.sty\\ +% refcount.pdf & doc/latex/refcount/refcount.pdf\\ +% refcount.dtx & source/latex/refcount/refcount.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 +% (\TeX\,Live, \mikTeX, \dots) relies on file name databases, you must refresh +% these. For example, \TeX\,Live\ users run \verb|texhash| or +% \verb|mktexlsr|. +% +% \subsection{Some details for the interested} +% +% \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{refcount.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 refcount.dtx +%makeindex -s gind.ist refcount.idx +%pdflatex refcount.dtx +%makeindex -s gind.ist refcount.idx +%pdflatex refcount.dtx +%\end{verbatim} +% \end{quote} +% +% \begin{History} +% \begin{Version}{1998/04/08 v1.0} +% \item +% First public release, written as answer in the +% newsgroup \xnewsgroup{comp.text.tex}: +% \URL{``\link{Re: Adding a \cs{ref} to a counter?}''}^^A +% {https://groups.google.com/group/comp.text.tex/msg/c3f2a135ef5ee528} +% \end{Version} +% \begin{Version}{2000/09/07 v2.0} +% \item +% Documentation added. +% \item +% LPPL 1.2 +% \item +% Package rewritten, new commands added. +% \end{Version} +% \begin{Version}{2006/02/20 v3.0} +% \item +% Support for \xpackage{hyperref} and \xpackage{nameref} improved. +% \item +% Support for \xpackage{titleref} and \xpackage{babel}'s shorthands added. +% \item +% New: \cs{refused}, \cs{getrefbykeydefault} +% \end{Version} +% \begin{Version}{2008/08/11 v3.1} +% \item +% Code is not changed. +% \item +% URLs updated. +% \end{Version} +% \begin{Version}{2010/12/01 v3.2} +% \item +% \cs{IfRefUndefinedExpandable} and \cs{IfRefUndefinedBabel} added. +% \item +% \cs{getrefnumber}, \cs{getpagerefnumber}, \cs{getrefbykeydefault} +% are expandable in exact two expansion steps. +% \item +% Non-expandable macros are made robust. +% \item +% Test files added. +% \end{Version} +% \begin{Version}{2011/06/22 v3.3} +% \item +% Bug fix: \cs{rc@refused} is undefined for \cs{setcounterpageref} +% and similar macros.
