Each of these is discussed in the next two subsections. - -\subsection{The \texorpdfstring{\protect\cs{ranToks}}{\CMD{ranToks}} command} - -The \cs{ranToks} command was the original concept; declare a series of -tokens to be randomized. -\bVerb\takeMeasure{\string\ranToks\darg{\meta{name}}\{\%\enspace}% -\begin{minipage}{\bxSize}\kern0pt -\begin{Verbatim}[frame=single,commandchars=!()] -\ranToks{!meta(name)}{% - {!meta(token!SUB(1))} - {!meta(token!SUB(2))} - ... - {!meta(token!SUB(n))} -} -\end{Verbatim} -\end{minipage}\eVerb -were \meta{token\SUB{k}} is any non-verbatim content;\footnote{Any token that -can be in the argument of a command.} each token is enclosed in braces -(\darg{}), this is required.

Of course several such \cs{ranToks} can be used in the document, -either in the preamble or in the body of the document. Multiple -\cs{ranToks} commands must have a different \meta{name} parameter. - -\emph{After} a \cs{ranToks} command has been executed, the number of tokens -counted is accessible through the \cs{nToksFor} command, -\bVerb\takeMeasure{\string\nToksFor\darg{\meta{name}}}% -\begin{minipage}{\bxSize}\kern0pt -\begin{Verbatim}[frame=single,commandchars=!()] -\nToksFor{!meta(name)} -\end{Verbatim} -\end{minipage}\eVerb -The one argument is \meta{name}, and will expand to the total number -of tokens listing as argument in the \cs{ranToks} command by the same -name. - -The \cs{ranToks} command does not display the randomized tokens, for that -the command \cs{useRanTok} is used. -\bVerb\takeMeasure{\string\useRTName\darg{\meta{name}}}% -\begin{minipage}{\bxSize} -\begin{Verbatim}[frame=single,commandchars=!()] -\useRanTok{!meta(num)} -\useRTName{!meta(name)} -\end{Verbatim} -\end{minipage}\eVerb -The argument of \cs{useRanTok} is a positive integer between 1 and -\cs{nToksFor\darg{\meta{name}}}, the number of tokens declared by -\cs{ranToks}, inclusive. There is no space created following the -\cs{useRanTok} command, so if these are to be used ``inline'', enclose them -in braces (\darg{}), for example, \darg{\cs{useRanTok\darg{1}}}. The use of -\cs{useRTName} is optional unless the listing of the \cs{useRanTok} commands -is separated from the \cs{ranToks} command that defined them by another -\cs{ranToks} command of a different name. That should be clear! - -Consider this example. - -\begin{Verbatim}[xleftmargin=\amtIndent] -\ranToks{myPals}{% - {Jim}{Richard}{Don} - {Alex}{Tom}{J\"{u}rgen} -} -\end{Verbatim} -\ranToks{myPals}{% - {Jim}{Richard}{Don} - {Alex}{Tom}{J\"{u}rgen} -} -I have {\nToksFor{myPals}} pals, they are \useRanTok{1}, \useRanTok{2}, -\useRanTok{3}, \useRanTok{4}, {\useRanTok{5}} and \useRanTok{6}. (Listed -in the order of best friend to least best friend.) -The verbatim listing is, -\begin{Verbatim}[xleftmargin=\amtIndent] -I have {\nToksFor{myPals}} pals, they are \useRanTok{1}, -\useRanTok{2}, \useRanTok{3}, \useRanTok{4}, {\useRanTok{5}} -and \useRanTok{6}. -\end{Verbatim} -Notice that \cs{useRanToks} are not enclosed in braces for 1--4 because -they are each followed by a comma; the fifth token, \texttt{\darg{\cs{useRanTok\darg{5}}}}, is -enclosed in braces to generate a space following the insertion of the text. - -Repeating the sentence yields, ``I have {\nToksFor{myPals}} pals, they are -\useRanTok{1}, \useRanTok{2}, \useRanTok{3}, \useRanTok{4}, -{\useRanTok{5}} and \useRanTok{6}'', which is the exact same random order. To -obtain a different order, re-execute the \cs{ranToks} command with the same -arguments.\footnote{{\ttfamily\string\ranToks\darg{myPals}\darg{\darg{Jim}\darg{Richard}\darg{Don}\darg{Alex}\darg{Tom}\darg{J\string\"\darg{u}rgen}}} in this example.} Doing just that, \ranToks{myPals}{{Jim}{Richard}{Don} -{Alex}{Tom}{J\"{u}rgen}}we obtain, ``I have {\nToksFor{myPals}} pals, they -are \useRanTok{1}, \useRanTok{2}, \useRanTok{3}, \useRanTok{4}, -{\useRanTok{5}} and \useRanTok{6}.''

For most applications, re-randomizing -the same token list in the same document is not very likely something you -need to do. - -The \cs{reorderRanToks\darg{\meta{name}}} rearranges the list of tokens -associated with \ameta{name}, which may not be what you want; the -\cs{copyRanToks} command, on the other hand, makes a (randomized) copy of its -first required argument \ameta{name\SUB1} and saves it as \ameta{name\SUB2}, without -effecting the order of \ameta{name\SUB1}. -\bVerb\takeMeasure{\string\copyRanToks\darg{\ameta{name\SUB1}}\darg{\ameta{name\SUB2}}}% -\begin{minipage}{\bxSize}\kern0pt -\begin{Verbatim}[frame=single,commandchars=!()] -\copyRanToks{!ameta(name!SUB1)}{!ameta(name!SUB2)} -\end{Verbatim} -\end{minipage}\eVerb Thus, if \verb!\copyRanToks{myPals}{myPals1}! is executed, the token list name -\texttt{myPals1} contains the names of my pals in another randomized order, -while maintaining the same order of \texttt{myPals}. - - -\newtopic -My original application for this, the one that motivated writing this -package at long last, was the need to arrange several form buttons -randomly on the page. My point is that the listing given in the argument -of \cs{ranToks} can pretty much be anything that is allowed to be an -argument of a macro; this would exclude verbatim text created by \cs{verb} -and verbatim environments. - -\subsection{The -\texorpdfstring{\protect\cs{bRTVToks}/\protect\cs{eRTVToks}} - {\CMD{bRTVToks}/\CMD{eRTVToks}} pair of commands}\label{ss:RTVToks} - -Sometimes the content to be randomized is quite large or contains verbatim -text.

The use of +\cs{useRTName} is optional unless the listing of the \cs{useRanTok} commands +is separated from the \cs{ranToks} command that defined them by another +\cs{ranToks} command of a different name.

For most applications, re-randomizing +the same token list in the same document is not very likely something you +need to do. + +The \cs{reorderRanToks\darg{\meta{name}}} rearranges the list of tokens +associated with \ameta{name}, which may not be what you want; the +\cs{copyRanToks} command, on the other hand, makes a (randomized) copy of its +first required argument \ameta{name\SUB1} and saves it as \ameta{name\SUB2}, without +effecting the order of \ameta{name\SUB1}. +\bVerb\takeMeasure{\string\copyRanToks\darg{\ameta{name\SUB1}}\darg{\ameta{name\SUB2}}}% +\begin{minipage}{\bxSize}\kern0pt +\begin{Verbatim}[frame=single,commandchars=!()] +\copyRanToks{!ameta(name!SUB1)}{!ameta(name!SUB2)} +\end{Verbatim} +\end{minipage}\eVerb Thus, if \verb!\copyRanToks{myPals}{myPals1}! is executed, the token list name +\texttt{myPals1} contains the names of my pals in another randomized order, +while maintaining the same order of \texttt{myPals}. + + +\newtopic +My original application for this, the one that motivated writing this +package at long last, was the need to arrange several form buttons +randomly on the page. My point is that the listing given in the argument +of \cs{ranToks} can pretty much be anything that is allowed to be an +argument of a macro; this would exclude verbatim text created by \cs{verb} +and verbatim environments. + +\subsection{The +\texorpdfstring{\protect\cs{bRTVToks}/\protect\cs{eRTVToks}} + {\CMD{bRTVToks}/\CMD{eRTVToks}} pair of commands}\label{ss:RTVToks} + +Sometimes the content to be randomized is quite large or contains verbatim +text.

The two optional arguments and the four commands may use +to perform logic on the token as it is being typeset.
