Only \cs{arabic} can be used with any counter +% value \hologo{TeX} supports. +% \begin{quote} +% \catcode`\|=12 % +% \begin{tabular}{@{}l|l|l|l@{}} +% Presentation & Supported & Ignored & Error message\\ +% command & domain & values & ``Counter too large''\\ +% \hline +% \cs{arabic} +% & \ttfamily -MAX..MAX & &\\ +% \cs{roman}, \cs{Roman} +% & \ttfamily 1..MAX & \ttfamily -MAX..0 &\\ +% \cs{alph}, \cs{Alph} +% & \ttfamily 1..26 & 0 & \ttfamily -MAX..-1, 27..MAX\\ +% \cs{fnsymbol} +% & \ttfamily 1..9 & 0 & \ttfamily -MAX..-1, 10..MAX\\ +% \hline +% \end{tabular}\\[1ex] +% \texttt{MAX} = \texttt{2147483647} +% \end{quote} +% Ordinal numbers are often used in documents: numbering +% of chapters, sections, figures, footnotes and so on. +% The layouter chooses \cs{Alph} for chapter numbers +% and \cs{fnsymbol} for footnotes. But what can be done +% if there are more than 26 chapters or more than 10 footnotes? +% This package \xpackage{alphalph} allows to define new +% presentation commands. They rely on a existing command +% and define presentations for values greater the limits. +% Three different methods are provided by the package. +% In the following use cases they are presentated. +% +% \subsection{Use cases} +% +% \subsubsection{Number system based on symbols} +% +% Asume you are writing a book and your lecturer demands +% that chapter numbers must be letters. But you have already +% 30 chapters and you have only 26 letters? +% +% In the decimal system the situation would be clear. +% If you run out of digits, you are using more digits +% to represent a number. This method can be also be used +% for letters. After chapter 26 with |Z| we us |AA|, |AB|, |AC|, and |AD| +% for the remaining chapters. +% +% Happily this package already defines this presentation command: +%\begin{quote} +%\begin{verbatim} +%\usepackage{alphalph} +%\renewcommand*{\thechapter}{% +% \AlphAlph{\value{chapter}}% +%} +%\end{verbatim} +%\end{quote} +% \cs{AlphAlph} generates: +% \AlphAlph{1}, \AlphAlph{2}, \AlphAlph{3}, \dots, +% \AlphAlph{26}, \AlphAlph{27}, \AlphAlph{28}, \dots +% +% The other presentation command is \cs{alphalph} for lowercase letters. +% +% \subsubsection{Wrap symbols around} +% +% Nine footnote symbols are quite a few. +% Too soon the symbols are consumed +% and \hologo{LaTeX} complains with the error ``Counter too large''. +% However, it could be acceptable to start again with the symbols +% from the beginning, especially if there are less than nine symbols +% on a page. +% This could be achieved by a counter reset. +% But finding the right place can be difficult or needs manual +% actions. Also a +% unique counter value can be desirable (e.g. for generating +% unique anchor/link names). +% Package \xpackage{alphalph} allows you to define +% a macro that implements a ``wrap around'', but letting +% the value of the counter untouched: +%\begin{quote} +%\begin{verbatim} +%\usepackage{alphalph} +%\makeatletter +%\newalphalph{\fnsymbolwrap}[wrap]{\@fnsymbol}{} +%\makeatother +%\renewcommand*{\thefootnote}{% +% \fnsymbolwrap{\value{footnote}}% +%} +%\end{verbatim} +%\end{quote} +% \cs{fnsymbolwrap} generates: +% \fnsymbolwrap{1}~(1), \fnsymbolwrap{2}~(2), \fnsymbolwrap{3}~(3), \dots, +% \fnsymbolwrap{9}~(9), \fnsymbolwrap{10}~(10), \fnsymbolwrap{11}~11, \dots +% +% \subsubsection{Multiple symbols} +% +% \Hologo{LaTeX}'s standard set of footnote symbols contains doubled +% symbols at the higher positions. Could this principle +% be generalized? +% Yes, but first we need a clean footnote symbol list without +% doubled entries, example: +%\begin{quote} +%\begin{verbatim} +%\usepackage{alphalph} +%\makeatletter +%\newcommand*{\fnsymbolsingle}[1]{% +% \ensuremath{% +% \ifcase#1% +% \or *% +% \or \dagger +% \or \ddagger +% \or \mathsection +% \or \mathparagraph +% \else +% \@ctrerr +% \fi +% }% +%} +%\makeatother +%\newalphalph{\fnsymbolmult}[mult]{\fnsymbolsingle}{} +%\renewcommand*{\thefootnote}{% +% \fnsymbolmult{\value{footnote}}% +%} +%\end{verbatim} +%\end{quote} +% The own definition of \cs{fnsymbolsingle} has the +% advantage that this list can easily modified. +% Otherwise you can use \cs{@fnsymbol} directly, +% because it uses the same first five symbols. +%\begin{quote} +%\begin{verbatim} +%\usepackage{alphalph} +%\makeatletter +%\newalphalph{\fnsymbolmult}[mult]{\@fnsymbol}{5} +%\makeatother +%\renewcommand*{\thefootnote}{% +% \fnsymbolmult{\value{footnote}}% +%} +%\end{verbatim} +%\end{quote} +% \cs{fnsymbolmult} generates: +% \fnsymbolmult{1}~(1), \fnsymbolmult{2}~(2), \fnsymbolmult{3}~(3), +% \fnsymbolmult{4}~(4), \fnsymbolmult{5}~(5), \fnsymbolmult{6}~(6), +% \dots, \fnsymbolmult{16}~16, \fnsymbolmult{17}~17, \dots +% +% \bigskip +% The same method can also be used for the chapter problem +% in the first discussed use case: +%\begin{quote} +%\begin{verbatim} +%\usepackage{alphalph} +%\makeatletter +%\newalphalph{\AlphMult}[mult]{\@Alph}{26} +%\makeatother +%\renewcommand*{\chapter}{% +% \AlphMult{\value{chapter}}% +%} +%\end{verbatim} +%\end{quote} +% \cs{AlphMult} then generates AA, BB, CC, and DD for chapters 27--30. +% +% \subsection{Glossary} +% +% \begin{description} +% \item[Counter presentation command] is a macro that +% expects a \hologo{LaTeX} counter name as argument. +% Numbers cannot be used. Examples: +% \cs{arabic}, \cs{alph}, \cs{fnsymbol}. +% \item[Number presentation command] is a macro that +% expects a number as argument. A number is anything +% that \hologo{TeX} accepts as number including \cs{value}. +% Examples: \cs{alphalph}, \cs{AlphAlph}, \cs{alphalph@alph} +% +% However, \cs{alph} or \cs{fnsymbol} are not number +% presentation commands because they expect a counter +% name as argument. Happily \hologo{LaTeX} counter presentation +% commands internally uses number presentation commands +% with the same name, but prefixed by `@'. Thus +% \cs{@alph}, \cs{@fnsymbol} are number presentation commands. +% \item[Symbols provider] is a command that can be used +% to get a list of symbols. For example, \cs{@Alph} +% provides the 26 uppercase letters from `A' to `Z'. +% Basically a symbol provider is a number presentation +% command, usually with a limited range. +% \item[Number of symbols] is the number of the +% last symbol slot of a symbol provider. Thus \cs{@Alph} +% generates 26 symbols, \cs{@fnsymbol} provides 9 symbols. +% \end{description} +% +% \subsection{Package usage} +% +% The package \Package{alphalph} can be used with both \hologo{plainTeX} +% and \hologo{LaTeX}: +% \begin{description} +% \item[\hologo{plainTeX}:] |\input alphalph.sty| +% \item[\hologo{LaTeX2e}:] |\usepackage{alphalph}|\\ +% There aren't any options. +% \end{description} +% +% \subsection{User commands} +% +% \begin{declcs}{AlphAlph} \M{number}\\ +% \cs{alphalph} \M{number} +% \end{declcs} +% Both macros are number presentation commands that +% expects a number as argument. \hologo{LaTeX} counters +% are used with \cs{value}. +% +% The macros represents a number by letters. +% First single letters |A..Z| are used, then +% two letters |AA..ZZ|, three letters |AAA...ZZZ|, \dots +% follow. +% +% Macro \cs{AlphAlph} uses uppercase letters, +% \cs{alphalph} generates the lowercase variant. +% \begin{quote} +% \catcode`\|=12 +% \def\entry#1{ +% \texttt{#1} +% & \texttt{\AlphAlph{#1}} +% & \texttt{\alphalph{#1}} +% } +% \begin{tabular}{@{}l|l|l@{}} +% \meta{number} & \verb|\AlphAlph{|\meta{number}\verb|}| +% & \verb|\alphalph{|\meta{number}\verb|}|\\ +% \hline +% \entry{1}\\ +% \entry{2}\\ +% \entry{26}\\ +% \entry{27}\\ +% \entry{30}\\ +% \entry{2000}\\ +% \entry{3752127}\\ +% \entry{10786572}\\ +% \entry{2147483647}\\ +% \end{tabular} +% \end{quote} +% +% \begin{declcs}{newalphalph} +% \M{cmd} +% |[|\meta{method}|]| +% \M{symbols provider} +% \M{number of symbols} +% \end{declcs} +% Macro \cs{newalphalph} defines \meta{cmd} as new +% number presentation command. Like \cs{newcommand} an error +% is thrown, if macro \meta{cmd} already exists. +% +% The \meta{method} is one of |alph|, |wrap|, or |mult|. +% The default is |alph|. +% +% As symbol provider a number presentation command +% can be used, e.g. \cs{@fnsymbol}, \cs{@Alph}, or +% \cs{alphalph@alph}. +% +% The last argument is the number of symbols. +% If the argument is empty, then \cs{newalphalph} tries +% to find this number itself. \hologo{LaTeX}'s number presentation +% commands throw an error message, if the number is too large. +% This error message is put in a macro \cs{@ctrerr}. +% Thus \cs{newalphalph} calls the symbol provider and tests +% a number by typesetting it in a temporary box. The error +% macro \cs{@ctrerr} is catched, it proofs that the number +% is not supported. Also if the width of the result is zero +% the number is considered as unavailable. +% +% The empty argument is useful for potentially variable lists. +% However if the end cannot be detected, then the number of +% symbols must be given. This is also a lot faster. Therefore don't +% let the argument empty without reason. +% +% \subsection{Programmer commands} +% +% \begin{declcs}{alphalph@Alph} \M{number}\\ +% \cs{alphalph@alph} \M{number} +% \end{declcs} +% They are basically the same as \cs{@Alph} and \cs{@alph}. +% Some languages of package \xpackage{babel} redefine +% \hologo{LaTeX}'s macros to include some font setup that +% breaks expandibility. Therefore \cs{AlphAlph} and \cs{alphalph} +% are based on \cs{alphalph@Alph} and \cs{alphalph@alph} to get +% the letters. The behaviour of these symbol providers for numbers +% outside the range |1..26| is undefined. +% +% \subsection{Design principles} +% +% \subsubsection{Number presentation commands} +% +% All number presentation commands that this package defines +% (including \cs{alphalph} and \cs{AlphAlph}) have the following +% properties: +% \begin{itemize} +% \item They are fully expandable. This means that they can safely +% \begin{itemize} +% \item be written to a file, +% \item used in moving arguments (\hologo{LaTeX}: they are \emph{robust}), +% \item used in a \cmd{\csname}-\cmd{\endcsname} pair. +% \end{itemize} +% \item If the argument is zero or negative, the commands expand +% to nothing like \cmd{\romannumeral}. +% \item The argument is a \hologo{TeX} number. Anything that would be +% accepted by \cmd{\number} is a valid argument: +% \begin{itemize} +% \item explicite constants, +% \item macros that expand to a number, +% \item count registers, \hologo{LaTeX} counter can used +% via \cmd{\value}, e.\,g.:\\ +% |\alphalph{\value{page}}| +% \item \dots +% \end{itemize} +% \item \hologo{eTeX}'s numeric expressions are supported, if \hologo{eTeX} is +% available. Then \cs{numexpr} is applied to the argument. +% Package \cs{calc}'s expressions are not supported. +% That would violate the expandibility. +% \end{itemize} +% +% \subsubsection{General usability} +% +% \begin{description} +% \item[\hologo{TeX} format:] +% The package does not depend on \hologo{LaTeX}, it can also be used +% by \hologo{plainTeX}, for example. +% \item[\hologo{eTeX}:] \eTeX is supported, the macros are shorter and +% faster. But \eTeX's extensions are not requirements. +% Without \hologo{eTeX}, just the implementation changes. The properties +% remain unchanged. +% \end{description} +% +% \StopEventually{ +% } +% +% \section{Implementation} +% \subsection{Begin\texorpdfstring{ of package}{}} +% \begin{macrocode} +%<*package> +% \end{macrocode} +% Reload check, especially if the package is not used with \LaTeX. +% \begin{macrocode} +\begingroup\catcode61\catcode48\catcode32=10\relax% + \catcode13=5 % ^^M + \endlinechar=13 % + \catcode35=6 % # + \catcode39=12 % ' + \catcode44=12 % , + \catcode45=12 % - + \catcode46=12 % . + \catcode58=12 % : + \catcode64=11 % @ + \catcode123=1 % { + \catcode125=2 % } + \expandafter\let\expandafter\x\csname ver@alphalph.sty\endcsname + \ifx\x\relax % plain-TeX, first loading + \else + \def\empty{}% + \ifx\x\empty % LaTeX, first loading, + % variable is initialized, but \ProvidesPackage not yet seen + \else + \expandafter\ifx\csname PackageInfo\endcsname\relax + \def\x#1#2{% + \immediate\write-1{Package #1 Info: #2.}% + }% + \else + \def\x#1#2{\PackageInfo{#1}{#2, stopped}}% + \fi + \x{alphalph}{The package is already loaded}% + \aftergroup\endinput + \fi + \fi +\endgroup% +% \end{macrocode} +% Package identification: +% \begin{macrocode} +\begingroup\catcode61\catcode48\catcode32=10\relax% + \catcode13=5 % ^^M + \endlinechar=13 % + \catcode35=6 % # + \catcode39=12 % ' + \catcode40=12 % ( + \catcode41=12 % ) + \catcode44=12 % , + \catcode45=12 % - + \catcode46=12 % . + \catcode47=12 % / + \catcode58=12 % : + \catcode64=11 % @ + \catcode91=12 % [ + \catcode93=12 % ] + \catcode123=1 % { + \catcode125=2 % } + \expandafter\ifx\csname ProvidesPackage\endcsname\relax + \def\x#1#2#3[#4]{\endgroup + \immediate\write-1{Package: #3 #4}% + \xdef#1{#4}% + }% + \else + \def\x#1#2[#3]{\endgroup + #2[{#3}]% + \ifx#1\@undefined + \xdef#1{#3}% + \fi + \ifx#1\relax + \xdef#1{#3}% + \fi + }% + \fi +\expandafter\x\csname ver@alphalph.sty\endcsname +\ProvidesPackage{alphalph}% + [2016/05/16 v2.5 Convert numbers to letters (HO)]% +% \end{macrocode} +% +% \subsection{Catcodes} +% +% \begin{macrocode} +\begingroup\catcode61\catcode48\catcode32=10\relax% + \catcode13=5 % ^^M + \endlinechar=13 % + \catcode123=1 % { + \catcode125=2 % } + \catcode64=11 % @ + \def\x{\endgroup + \expandafter\edef\csname AlPh@AtEnd\endcsname{% + \endlinechar=\the\endlinechar\relax + \catcode13=\the\catcode13\relax + \catcode32=\the\catcode32\relax + \catcode35=\the\catcode35\relax + \catcode61=\the\catcode61\relax + \catcode64=\the\catcode64\relax + \catcode123=\the\catcode123\relax + \catcode125=\the\catcode125\relax + }% + }% +\x\catcode61\catcode48\catcode32=10\relax% +\catcode13=5 % ^^M +\endlinechar=13 % +\catcode35=6 % # +\catcode64=11 % @ +\catcode123=1 % { +\catcode125=2 % } +\def\TMP@EnsureCode#1#2{% + \edef\AlPh@AtEnd{% + \AlPh@AtEnd + \catcode#1=\the\catcode#1\relax + }% + \catcode#1=#2\relax +} +\TMP@EnsureCode{33}{12}% ! +\TMP@EnsureCode{39}{12}% ' +\TMP@EnsureCode{40}{12}% ( +\TMP@EnsureCode{41}{12}% ) +\TMP@EnsureCode{43}{12}% + +\TMP@EnsureCode{44}{12}% , +\TMP@EnsureCode{46}{12}% . +\TMP@EnsureCode{47}{12}% / +\TMP@EnsureCode{59}{12}% ; +\TMP@EnsureCode{60}{12}% < +\TMP@EnsureCode{62}{12}% > +\TMP@EnsureCode{91}{12}% [ +\TMP@EnsureCode{93}{12}% ] +\TMP@EnsureCode{96}{12}% ` +\TMP@EnsureCode{124}{12}% | +\edef\AlPh@AtEnd{\AlPh@AtEnd\noexpand\endinput} +% \end{macrocode} +% +% \subsection{Package loading} +% +% \begin{macrocode} +\begingroup\expandafter\expandafter\expandafter\endgroup +\expandafter\ifx\csname RequirePackage\endcsname\relax + \input infwarerr.sty\relax + \input intcalc.sty\relax +\else + \RequirePackage{infwarerr}[2007/09/09]% + \RequirePackage{intcalc}[2007/09/09]% +\fi +% \end{macrocode} +% +% \subsection{\hologo{eTeX} detection} +% +% \begin{macrocode} +\begingroup\expandafter\expandafter\expandafter\endgroup +\expandafter\ifx\csname numexpr\endcsname\relax + \catcode124=9 % '!': ignore + \catcode43=14 % '+': comment +\else + \catcode124=14 % '!': comment + \catcode43=9 % '+': ignore +\fi +% \end{macrocode} +% +% \subsection{Help macros} +% +% \begin{macro}{\AlPh@Error} +% \begin{macrocode} +\def\AlPh@Error#1{% + \begingroup + \escapechar=92 % backslash + \@PackageError{alphalph}{#1}\@ehc + \endgroup +} +% \end{macrocode} +% \end{macro} +% +% \begin{macro}{\AlPh@IfDefinable} +% \begin{macrocode} +\begingroup\expandafter\expandafter\expandafter\endgroup +\expandafter\ifx\csname @ifdefinable\endcsname\relax + \def\AlPh@IfDefinable#1#2{% + \ifcase\ifx#1\@undefined\else\ifx#1\relax\else1\fi\fi0 % + #2% + \else + \AlPh@Error{% + Command \string#1 already defined% + }% + \fi + }% +% \end{macrocode} +% \end{macro} +% \begin{macrocode} +\else +% \end{macrocode} +% \begin{macro}{\AlPh@IfDefinable} +% \begin{macrocode} + \let\AlPh@IfDefinable\@ifdefinable +% \end{macrocode} +% \end{macro} +% \begin{macrocode} +\fi +% \end{macrocode} +% +% \begin{macro}{\@ReturnAfterElseFi} +% \begin{macro}{\@ReturnAfterFi} +% The following commands moves the `then' and `else' part respectively +% behind the |\if|-construct.

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 alphalph.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@{}} +% alphalph.sty & tex/generic/oberdiek/alphalph.sty\\ +% alphalph.pdf & doc/latex/oberdiek/alphalph.pdf\\ +% test/alphalph-test1.tex & doc/latex/oberdiek/test/alphalph-test1.tex\\ +% test/alphalph-test2.tex & doc/latex/oberdiek/test/alphalph-test2.tex\\ +% test/alphalph-test3.tex & doc/latex/oberdiek/test/alphalph-test3.tex\\ +% alphalph.dtx & source/latex/oberdiek/alphalph.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 alphalph.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{alphalph.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 alphalph.dtx +%makeindex -s gind.ist alphalph.idx +%pdflatex alphalph.dtx +%makeindex -s gind.ist alphalph.idx +%pdflatex alphalph.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{alphalph.xml}. +% \begin{macrocode} +%<*catalogue> +<?xml version='1.0' encoding='us-ascii'?> +<!DOCTYPE entry SYSTEM 'catalogue.dtd'> +<entry datestamp='$Date$' modifier='$Author$' id='alphalph'> + <name>alphalph</name> + <caption>Convert numbers to letters.</caption> + <authorref id='auth:oberdiek'/> + <copyright owner='Heiko Oberdiek' year='1999,2006-2008,2010,2011'/> + <license type='lppl1.3'/> + <version number='2.5'/> + <description> + Provides commands <tt>\alphalph</tt> and <tt>\AlphAlph.</tt> They + are like <tt>\number</tt> but the expansion consists of lowercase + and uppercase letters respectively (1 to a, 26 to z, 27 to aa, 52 + to zz, 53 to ba, 702 to zz, 703 to aaa, etc.).
