They all had more or less the following structure: \begin{sourcecode} \makeatletter \newcommand*\cmd{\@ifstar\cmd@star\cmd@nostar} \newcommand*\cmd@star[1]{\cmd@base{#1}} \newcommand*\cmd@nostar[1]{\cmd@base{#1}\cmd@idx{#1}} \newcommand*\cmd@base[1]{\textit{#1}} \newcommand*\cmd@idx[1]{\index{#1@\cmd@base{#1}}} \makeatother \end{sourcecode} After having copied and pasted this code for the fourth time I thought: you should have a command that does this for you. That was when \cs{newidxcmd} was born. This command soon enough got some extensions, \eg, giving the commands thus defined an optional argument that allowed specifying the sorting. It wasn't long before I realized that I might want to use this \cs{newidxcmd} again in other documents which was when I wrote the first draft of this package. I added other commands, \cs{newsubmainidxcmd} and \cs{newsubidxcmd}, which I didn't (and still don't) really use or need but of which I thought they could be useful for others, and here we are. \section{Usage}\label{sec:usage} \subsection{Available Commands} \idxcmds\ provides these commands: \begin{commands} \command{newidxcmd}[\oarg{index cs}\marg{cs}\marg{formatting specs}\oarg{append}] Defines a command \meta{cs} that formats its argument according to \meta{formatting specs} and creates an index entry with \meta{index cs} that gets \meta{append} appended. Refer to the argument of \meta{cs} in \meta{formatting specs} with \code{\#1}. Also defines a command \cs*{\meta{cs}idx} that allows to only create an index entry. See section~\ref{sec:command:usage:newidxcmd} for examples and further description of its functionality. Default for \meta{index cs} is \cs{index}. \command{newsubidxcmd}[\sarg\oarg{index cs}\marg{cs}\marg{main entry}\marg{form. specs}\oarg{append}] Defines a command \meta{cs} that formats its argument according to \meta{form. specs} and creates an index sub-entry to \meta{main entry} with \meta{index cs} that gets \meta{append} appended. Refer to the argument of \meta{cs} in \code{form.\@ specs} with \code{\#1}. Also defines a command \cs*{\meta{cs}idx} that allows to only create an index entry. See section~\ref{sec:command:usage:newsubidxcmd} for further description of its functionality. Default for \meta{index cs} is \cs*{index}. \command{newsubmainidxcmd}[\oarg{index cs}\marg{cs}\marg{form. specs}\oarg{append}] Defines a command \meta{cs} that formats its argument according to \meta{form. specs} and creates an index sub-entry to a main entry with \meta{index cs} that gets \meta{append} appended. Refer to the argument of \meta{cs} in \meta{form. specs} with \code{\#1}. Also defines a command \cs*{\meta{cs}idx} that allows to only create an index entry. The main entry is specified at use time. See section~\ref{sec:command:usage:newsubmainidxcmd} for examples and further description of its functionality. Default for \meta{index cs} is \cs*{index}. \end{commands} The commands \meta{cs} defined this way are robust but their formatting argument is not placed in a group. Keep this in mind when you use \cs*{bfseries} or something in a definition. \meta{cs} will be defined using \pkg{etoolbox}' \cs*{newrobustcmd} which means an error will be thrown if \meta{cs} is already defined. Of course these commands cannot cover all possible use cases for index entries but that is not the intention of this package, anyway. \subsection{Command Usage}\label{sec:command:usage} \subsubsection{\cs*{newidxcmd}}\label{sec:command:usage:newidxcmd} The command \cs{newidxcmd}\Marg{\cs*{foo}}\marg{formatting specs} will define a new command \cs*{foo} with the following syntax: \begin{commands} \command*{foo}[\sarg\marg{text}] format \meta{text} according to specifications, no index entry. \command*{foo}[\oarg{sort idx}\marg{text}\oarg{append}] format \meta{text} according to specifications, add formatted index entry, sorted according to \meta{sort idx} or, if the optional argument is left out, sorted according to \meta{text}. \meta{append} is added to the index entry if the trailing optional argument is used (this can be useful for instance for getting formatted page numbers). \command*{fooidx}[\oarg{sort idx}\marg{text}\oarg{append}] add formatted index entry, sorted according to \meta{sort idx} or, if the optional argument is left out, sorted according to \meta{text}. \meta{append} is added to the index entry if the trailing optional argument is used. \end{commands} Let's see an example: \begin{example} % in the preamble, probably: % \newidxcmd{\acr}{\textsc{#1}} % \newidxcmd[{\index[environments]}]{\environ}{\texttt{#1}}[ (Environment)] % \newidxcmd{\scientist}{\textsf{#1}} \acr{cd}, \acr{id} \environ{center}, \environ{flushleft} \scientist*{Albert Einstein}, \scientist[Heisenberg]{Werner Heisenberg} \end{example} You will find these examples in the index of examples or the index of environments, respectively. The second set of examples shows the purpose of the first optional argument: if you have several indexes --~like this documentation has for demonstration purposes~-- you might need to specify the index command used\footnote{This document uses \pkg{imakeidx}~\cite{pkg:imakeidx} for this purpose.}. If you want to prove if the example worked: \scientist*{Albert Einstein} should not be found in the index and \scientist*{Werner Heisenberg} should be sorted under \emph{Heisenberg}. Both \environ*{center} and \environ*{flushleft} ahould be found in the examples index. Now let's disect the example a bit. The uses of \cs*{acr}\Marg{cd}, \cs*{scientist}\sarg\Marg{Albert Einstein} and \cs*{environ}\Marg{center} will essentially expand to \begin{sourcecode} % \acr{cd} => \textsc{cd}\index{cd@\textsc{cd}} % and in \jobname.idx => \indexentry{cd@\textsc {cd}}{3} % \scientist*{Albert Einstein} => \textsf{Albert Einstein} % \environ{center} => \texttt{center}\index[environments]{center@\texttt{center} (Environment)} % and in examples.idx => \indexentry{center@\texttt {center} (Environment)}{3} \end{sourcecode} \subsubsection{\cs*{newsubidxcmd}}\label{sec:command:usage:newsubidxcmd} The command \cs{newsubidxcmd}\sarg\Marg{\cs*{foo}}\marg{main entry}\marg{form. specs} will define a new command \cs*{foo} with the same syntax as \cs{newidxcmd} does. However, \cs{newsubidxcmd} has an additional argument that specifies the main index entry this group of sub entries belongs to. For the unstarred variant this argument can be some arbitrary main entry. For the starred variant it demands a command plus argument defined by \cs{newidxcmd} as argument. \begin{example} % preamble: % \newsubidxcmd{\test}{Test}{\textcolor{red}{#1}} % \newsubidxcmd*{\hsnbg}{\scientist[Heisenberg]{Werner Heisenberg}}{#1} \scientist[Heisenberg]{Werner Heisenberg} was born in \hsnbg[Wuerzburg]{W\"urzburg (Germany)}. He worked as a professor in \hsnbg{Leipzig (Germany)}. And this is a \test{test}. \end{example} \subsubsection{\cs*{newsubmainidxcmd}}\label{sec:command:usage:newsubmainidxcmd} The command \cs{newsubmainidxcmd}\Marg{\cs*{foo}}\marg{form. specs} will define a new command \cs*{foo} similar to \cs{newsubidxcmd} but where the main index entry is specified for every use case in the running text. \cs*{foo} will have the following syntax: \begin{commands} \command*{foo}[\sarg\marg{text}] format \meta{text} according to specifications, no index entry. \command*{foo}[\oarg{sort idx}\marg{text}\marg{main entry}\oarg{append}] format \meta{text} according to specifications, add formatted index sub-entry to the main index entry \meta{main entry}, sorted according to \meta{sort idx} or, if the optional argument is left out, sorted according to \meta{text}. \meta{append} is added to the index entry if the trailing optional argument is used (this can be useful for instance for getting formatted page numbers). \command*{fooidx}[\oarg{sort idx}\marg{text}\marg{main entry}\oarg{append}] add formatted index sub-entry to the main index entry \meta{main entry}, sorted according to \meta{sort idx} or, if the optional argument is left out, sorted according to \meta{text}. \meta{append} is added to the index entry if the trailing optional argument is used. \end{commands} \begin{example} % in the preamble, probably: % \newsubmainidxcmd{\file}{\textsf{#1}} \file{article}{classes} is a standard \LaTeX{} class. \file{scrartcl}{KOMA-Script@\KOMAScript} is part of the \KOMAScript{} bundle. \file*{test} is a dummy. \end{example} \subsection{Options} \idxcmds\ has the following options -- either setable as package option or with the setup command \cs{setidxcmds}\marg{options} which takes a comma separated list of options: \begin{options} \keyval{sort-sep}{symbol}\Default{@} set makeindex symbol to separate the index into sorting and typesetting part as specified in the index style file. \keyval{sub-sep}{symbol}\Default{!} set makeindex symbol to add a sub entry as specified in the index style file. \keyval{idx-cmd}{cs}\Default{\cs*{index}} \sinceversion{0.2b}The default indexing command that is used by \idxcmds. \end{options} % \end{document} \printbibliography % \section{Implementation} % In the following code the lines 1--32 have been omitted.
