+% \title{Improved reference formatting for \LaTeX2e}
+%
+% \author{Kevin S. Ruland}
+%
+% \maketitle
+%
+% There is a significant change to the newrefformat command in
+% version~3.0. Please see the new discussion of that command below.
+%
+% This package has been completely reimplemented (in version 2.0).
+% Please note the user level commands have changed syntax. This was done
+% because most of the packages providing hypertext/www functionality
+% (such as, |hyper|, |hyperref| and |latex2html|)
+% also modify the |\newlabel| structure. In order to make this package
+% compatable with those, I have decided not to change the |\newlabel|
+% structure, but have the refence type stored in the label name.
+%
+% This package provides additional functionality to \LaTeX2e label--reference
+% mechanism. It allows the author to ``preformat'' all types of labels.
+%
+% A long standing problem with \LaTeX\ |\ref| command is that it only
+% provides a raw number. The author is responsible for properly formatting
+% the number correctly. For example, in order to correctly format a reference
+% to an equation, the author must use |\textup{(\ref{eq:1})}|. Or similarly
+% for a figure, |Figure~(\ref{fig:2})|. This way the ``format'' of the
+% reference is hard coded into the paper. If the author decides to change
+% figure references to |Figure~\ref{fig:2}|, she must search and replace all
+% the strings in the tex source.
+%
+% AMS\LaTeX\ has partially addressed this problem by providing the package
+% |upref| and command |\eqref| in |amsmath|. This is a partial solution
+% for equation numbers and forces equation numbers in upright style.
+%
+% This package provides a more comprehensive solution by allowing the author
+% to define various formats for the labels. For example, to label a
+% table the author would use |\label{tab:1}|. To access the formatted
+% reference the author uses |\prettyref{tab:1}|. |\pageref{tab:1}|
+% and |\ref{tab:1}| work as usual.
+%
+% |\prettyref| is robust enough to be used within |\caption| and in
+% |theorem| optional arguements.
+%
+% Labels in the document must be of the form |format:name| where the
+% string |format| is used to determine the format. Do not use the character
+% |:| anywhere within the label except to seperate |format| from
+% |name|. |format:name| must be unique for it is used as the label.
+%
+% \begin{macrocode}
+\ProvidesPackage{prettyref}[1998/07/09 v3.0]
+% \end{macrocode}
+%
+% \DescribeMacro{\newrefformat}
+% The command |\newrefformat| defines formats for pretty references.
+%
+% Usage: |\newrefformat{NAME}{FORMAT}|
+%
+% The |NAME| arguement is the name of the refernece type.
+%
+% The |FORMAT| argument is interpreted as the replacement text for
+% an internal one-argument function.
+% The |#1| will be replaced with the label name.
+% \begin{macrocode}
+\def\newrefformat#1#2{%
+ \@namedef{pr@#1}##1{#2}}
+% \end{macrocode}
+%
+% These define the default formats for table, eq, lemma, thm, section, and
+% figure. They also demonstrate the useage of |\newrefformat|.
+% \begin{macrocode}
+\newrefformat{eq}{\textup{(\ref{#1})}}
+\newrefformat{lem}{Lemma \ref{#1}}
+\newrefformat{thm}{Theorem \ref{#1}}
+\newrefformat{cha}{Chapter \ref{#1}}
+\newrefformat{sec}{Section \ref{#1}}
+\newrefformat{tab}{Table \ref{#1} on page \pageref{#1}}
+\newrefformat{fig}{Figure \ref{#1} on page \pageref{#1}}
+% \end{macrocode}
+%
+% \DescribeMacro{\prettyref}
+% The character |:| is used as a seperator. It must be appended to
+% the label string to terminate the |name| portion.
+%
+% \begin{macrocode}
+\def\prettyref#1{\@prettyref#1:}
+% \end{macrocode}
+%
+% \DescribeMacro{\@prettyref}
+% The internal macro |\@prettyref| does all the work. It takes two
+% arguements delimited by |:|. The first arguement is the format name.
+% If the format has not been defined, a warning is issued and |\ref|
+% is used. Otherwise, the reference is formatted. |\@prettyref|
+% uses the \LaTeX\ macros |\ref| and |\pageref| to access the
+% |\newlabel| data structure. Hopefully this makes the package
+% robust enough to use with various other pacakges.
+%
+% \begin{macrocode}
+\def\@prettyref#1:#2:{%
+ \expandafter\ifx\csname pr@#1\endcsname\relax%
+ \PackageWarning{prettyref}{Reference format #1\space undefined}%
+ \ref{#1:#2}%
+ \else%
+ \csname pr@#1\endcsname{#1:#2}%
+ \fi%
+}
+% \end{macrocode}
