+% \noindent This package provides facilities for hard-wrapping text to a certain
+% line width. The primary purpose is to make it easier for package authors to write
+% readable informational messages to the console and log file;
+% wrappers around \cs{PackageWarning} \etal\ are provided for this.

+% \section{Introduction}
+%
+% The \pkg{\jobname} package provides a macro for word-wrapping text. In
+% addition, helper macros are available for package and document class authors
+% to use in automatically wrapping informational, warning, and error messages.
+% This package requires \hologo{eTeX}.
+%
+% \section{Wrapping text}
+%
+% The main function provided by this package is the \cs{HardWrap} command,
+% which takes five arguments.
+% \begin{quote}
+% \cs{HardWrap} \marg{function} \marg{width} \marg{setup code} \marg{newline} \marg{text}
+% \end{quote}
+% This command will wrap \meta{text} to a text block of \meta{width} characters
+% wide, inserting \meta{newline} at the end of each line and processing the
+% result with \meta{function}. The \meta{text} is fully expanded before being
+% hard-wrapped; while doing so, the \meta{setup code} may be used to change
+% local command definitions.
+%
+% Inside \meta{text}, you may use \verb|\\| to force a new line and \verb*|\ | to
+% insert a space.
+% A literal \verb|^^J| will also be treated as a forced \meta{newline}.
+%
+% Examples will be given in \secref{sec:examples}.
+%
+% \section{Wrapping log messages}
+%
+% A common use case for the \cs{HardWrap} macro is to format the
+% informational, warning, and error messages that are printed to the terminal
+% and log file. In support of this, we've provided a simple interface for
+% package and document class authors to do this.
+%
+% \begin{quote}
+% \cs{GenerateLogMacros}\earg{package}\oarg{prefix}\marg{package name}\\
+% \cs{GenerateLogMacros}\earg{class}\texttt{\space \space}\oarg{prefix}\marg{class name}
+% \end{quote}
+% If the optional argument \meta{prefix} is not given, it is set equal to \meta{package name}.
+% These two commands will generate the following macros:
+%
+% \begin{quote}
+% \cs{\meta{prefix}@info}\marg{info}\\
+% \cs{\meta{prefix}@info@noline}\marg{info}\\
+% \cs{\meta{prefix}@warning}\marg{warning}\\
+% \cs{\meta{prefix}@warning@noline}\marg{warning}\\
+% \cs{\meta{prefix}@error}\marg{error}\marg{help}
+% \end{quote}
+%
+% For instance, calling \cs{GenerateLogMacros}\earg{package}\earg{mypackage}
+% will create macros called \cs{mypackage@info}, \cs{mypackage@warning}, \etc,
+% which internally use \cs{PackageInfo}, \cs{PackageWarning}, and so on, to
+% handle their respective messages.
+% The arguments for the generated macros are the same as the arguments for
+% \cs{PackageInfo}\marg{package name}, \cs{PackageWarning}\marg{package name}, \etc. Additionally, info messages may be printed with
+% \cs{\meta{prefix}@info@noline} in which \LaTeX's
+% `\texttt{on input line \meta{num}}' suffix is suppressed.
+%
+% The \cs{GenerateLogMacros}\earg{class} command instead generates analogous
+% macros using \cs{ClassInfo}\marg{\rmfamily class name},
+% \cs{ClassWarning}\marg{\rmfamily class name}, \etc.
+%
+% Note that no punctuation is added after messages, unlike standard \LaTeX.
+% You are free to punctuate your messages as you wish.
+%
+% As with the \cs{HardWrap} command,
+% \verb*|\ | and \verb|\\| are defined locally inside these messages to
+% mean, respectively, \meta{space} and \meta{newline}.
+%
+% Additional redefinitions are stored in the macro \cs{HardWrapSetup}, which may
+% be altered before executing \cs{GenerateLogMacro} to change the behaviour
+% of the generated commands. By default, \cs{HardWrapSetup} is defined as
+% \begin{Verbatim}
+% \def\HardWrapSetup{%
+% \def\MessageBreak{\\}%
+% \def\newline{\\}%
+% \def\emph##1{\string_##1\string_}%
+% \def\textit##1{/##1/}%
+% \def\textbf##1{*##1*}%
+% }
+% \end{Verbatim}
+% The redefinitions for \cs{emph}, \cs{textit}, and \cs{textbf} are examples
+% of the type of customisation you might like to perform.
+%
+% \section{Changing the line lengths}
+%
+% While \pkg{\jobname} attempts to determine the appropriate line
+% lengths, you may wish to override the value found using
+% \cs{setmaxprintline}\marg{value}.
+% This macro takes an integer value which is subsequently used as the
+% maximum line width allowed in the terminal output and log file. By default
+% this value is~\texttt{79}.
+%
+% \section{Examples}
+% \label{sec:examples}
+%
+% The command
+% \begin{Verbatim}
+% \HardWrap{\PackageWarning{foobar}}{50}{\HardWrapSetup}{\MessageBreak}{%
+% Sed feugiat. Cum sociis natoque...;}
+% \end{Verbatim}
+% produces the following in the console output:
+% \begin{Verbatim}[fontsize=\footnotesize]
+% Package foobar Warning: Sed feugiat. Cum sociis natoque penatibus et magnis
+% (foobar) dis parturient montes, nascetur ridiculus mus. Ut
+% (foobar) pellentesque augue sed urna. Vestibulum diam eros,
+% (foobar) fringilla et, consectetuer eu, nonummy id, sapien.
+% (foobar) Nullam at lectus. In sagittis ultrices mauris.
+% (foobar) Curabitur malesuada erat sit amet massa. Fusce
+% (foobar) blandit. Aliquam erat volutpat. Aliquam euismod.
+% (foobar) Aenean vel lectus. Nunc imperdiet justo nec
+% (foobar) dolor; on input line 102.
+% \end{Verbatim}
+% Compare this to the following without the manual wrapping; \TeX\ breaks
+% lines at 79 characters without keeping words together (\eg, `Vestibulum'
+% broken between lines two and three):
+% \begin{Verbatim}[fontsize=\footnotesize]
+% Package foobar Warning: Sed feugiat. Cum sociis natoque penatibus et magnis dis
+% parturient montes, nascetur ridiculus mus. Ut pellentesque augue sed urna. Ves
+% tibulum diam eros, fringilla et, consectetuer eu, nonummy id, sapien. Nullam at
+% lectus. In sagittis ultrices mauris. Curabitur malesuada erat sit amet massa.
+% Fusce blandit. Aliquam erat volutpat. Aliquam euismod. Aenean vel lectus. Nunc
+% imperdiet justo nec dolor; on input line 110.
+% \end{Verbatim}
+%
+% The \cs{HardWrap} macro can also be useful when writing to an external file.
+% For example, one may use:
+% \begin{Verbatim}
+% \newwrite\textfile
+% \immediate\openout\textfile=\jobname.txt\relax
+% \HardWrap{\immediate\write\textfile}{50}{\HardWrapSetup}{^^J}{%
+% Sed feugiat. Cum sociis natoque...;}
+% \closeout\textfile
+% \end{Verbatim}
+% to write the text to a file after being hard-wrapped with carriage returns (\verb|^^J|) after each line.

+}
+% \end{macrocode}
+% \end{macro}
+%
+%
+% \section{Main procedure}
+%
+% The idea for hard-wrapping the text is to assume we can fully expand the
+% argument and then iterate character-by-character over the message inserting
+% \meta{newline} commands where appropriate. The steps are:
+% \begin{enumerate}
+% \item Make local redefinitions for general commands, including special
+% placeholders for \meta{space} and \meta{newline}.
+% \item Fully expand the text-to-be-wrapped with appropriate definitions of
+% \cs{protect} and \cs{noexpand} so the resultant text can be assumed to
+% completely `safe' to scan over (and continue expanding) but \emph{without}
+% removing important macro placeholders for \meta{space} and \meta{newline}.
+% \item Then scan character by character. Whenever a space is found, check the
+% last word length and either append the word to the current line if it will
+% fit, or start a new line with a forced line break represented by another
+% special placeholder macro. Spaces are represented with placeholders so
+% multiple spaces don't collapse according to \TeX's usual space-handling
+% rules.
+% \item Finally process the wrapped text with appropriate meanings for the
+% placeholder macros.
+% \end{enumerate}
+%
+% \begin{macro}{\HardWrap}
+% Here's the main command that implements the steps outlined above.
+% Arguments:
+% \begin{enumerate}\parskip=0pt\itemsep=0pt
+% \item \marg{function}
+% \item \marg{chars to wrap to}
+% \item \marg{setup}
+% \item \marg{newline}
+% \item \marg{text}
+% \end{enumerate}
+% This is the macro that does everything.
+% Note that the \cs{space} is first made `protected' and then restored again.
+% \begin{macrocode}
+\newcommand*\HardWrap[5]{%
+ \begingroup
+ \hw@maxprintline=#2\relax
+% \end{macrocode}
+% Replacements for user commands:
+% \begin{macrocode}
+ \let\space\hw@protected@space
+ \def\ {\space}%
+ \let\\\hw@insert@newline
+% \end{macrocode}
+% To avoid problems with repeated edef with arbitrary csnames:
+% \begin{macrocode}
+ \let\noexpand\string
+% \end{macrocode}
+% Execute the custom setup, and then fully expand the text
+% to be wrapped, turning \cs{protect}ed macros into strings.
+% (Fully \cs{protected} macros will still be actual control sequences
+% at this point.)
+% \begin{macrocode}
+ \begingroup
+ #3%
+ \let\protect\string
+ \xdef\@tempa{#5}%
+ \endgroup
+% \end{macrocode}
+% Now scan over the text token by token, transforming it into an
+% intermediate representation of fully wrapped text.
+% Then fully expand this intermediate for into its final form,
+% ready to be processed by the input function \verb|#1|.
+% \begin{macrocode}

+% Convenience wrapper for \cs{futurelet}.
+% \begin{macrocode}
+\def\hw@scan{%

+}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\hw@process}
+% The \cs{hw@process} macro contains the actual word-wrapping algorithm.
+% The text is scanned token by token. Each token falls into one of four
+% categories: (1)~the stop token \cs{hw@scanstop}, (2)~a space token,
+% (3)~a newline insertion, or (4)~anything else.
+%
+% \begin{enumerate}
+% \item
+% If we encounter the \cs{hw@scanstop} token, then we've hit the end of the
+% string. Swallow the stop token and stop processing.
+% \item
+% If we find a space, add the word to the current line if it fits, otherwise
+% insert a line break and put the word on its own line. Continue reading tokens.
+% \item
+% If we find an explicit `newline', we process it much as if it were a space and
+% the current word is the last one that can fit on the line.
+% To continue, skip the actual token that is the `newline' and then start scanning again.
+% \item
+% If the token doesn't fall into one of the above special cases, we'll just append it to
+% the current word and continue reading tokens.
+% \end{enumerate}
+% \begin{macrocode}

+%
+% \section{Wrapping log messages}
+%
+% \begin{samepage}
+% \LaTeX{} informational, warning, and error messages are printed in the
+% format:
+% \begin{center}
+% \ttfamily\small
+% \begin{tabular}{l@{\space}l}
+% Package \meta{pkgname} Info: & This is an informational message.\\
+% (\meta{pkgname}) & That spans multiple lines. The\\
+% (\meta{pkgname}) & \string\MessageBreak\space macro is used to split\\
+% (\meta{pkgname}) & the text across lines.\\
+% \leftarrowfill$A$\rightarrowfill & \leftarrowfill$B$\rightarrowfill\\
+% \multicolumn{2}{c}{\leftarrowfill$\textrm{\textit{max\_print\_line}}$\rightarrowfill}
+% \end{tabular}
+% \end{center}
+% \end{samepage}
+% The maximum line length ($\textit{max\_print\_line}$) is used by
+% \TeX{} for all log file and terminal output. It defaults to 79 characters
+% but may be changed by editing the \texttt{texmf.cnf} file.
+%
+% The length of $A$ is the sum of three values:
+% \begin{enumerate}
+% \item whether it's a class or package message: add 6 for class messages,
+% and 8 for package messages;
+% \item the length of the package name;
+% \item the type of message: information (add 7), warning (add 10), or error
+% (add~10).
+% \end{enumerate}
+% The length of $B$ is the difference between $\textit{max\_print\_line}$ and
+% $A$ plus one for the extra space between them.
+% Note that the length of $B$ for the warning and error text is the same.
+%
+% \begin{macro}{\hw@suffix}
+% This string is used as a suffix to \LaTeX\ warnings and info messages
+% to push the automatic `on input line \meta{num}' onto the next line.
+% This makes writing grammatically correct messages somewhat easier.
+% \begin{macrocode}
+\newcommand\hw@suffix{^^JThis message occurred}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\GenerateLogMacros}
+% Shortcuts are provided for generating logging macros that automatically wrap
+% the text provided to them. The \cs{GeneratePackageLogMacros} and
+% \cs{GenerateClassLogMacros} calculate the various lengths of $B$
+% appropriately.
+% \begin{macrocode}
+\newcommand\GenerateLogMacros[1]{%
+ \lowercase{\def\hw@tempa{#1}}%
+ \def\hw@tempb{package}%
+ \ifx\hw@tempa\hw@tempb
+ \expandafter\GeneratePackageLogMacros
+ \else
+ \def\hw@tempb{class}%
+ \ifx\hw@tempa\hw@tempb
+ \expandafter\expandafter\expandafter\GenerateClassLogMacros
+ \else
+ \PackageError{hardwrap}{\MessageBreak
+ \string\GenerateLogMacros\space only accepts "package"
+ \MessageBreak or "class" types%
+ }{%
+ E.g., \detokenize{\GenerateLogMacros{package}[HW]{hardwrap}}%
+ }%
+ \fi
+ \fi
+}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\GeneratePackageLogMacros,\GenerateClassLogMacros}
+% \begin{macrocode}
+\newcommand{\GeneratePackageLogMacros}[2][]{%
+ \hw@generate@logging@macros{package}{#1}{#2}%
+ {\hw@maxprintline-\hw@strlen{#2}-16}% info length
+ {\hw@maxprintline-\hw@strlen{#2}-19}% warning length
+}
+% \end{macrocode}
+%
+% \begin{macrocode}
+\newcommand{\GenerateClassLogMacros}[2][]{%
+ \hw@generate@logging@macros{class}{#1}{#2}%
+ {\hw@maxprintline-\hw@strlen{#2}-14}% info length
+ {\hw@maxprintline-\hw@strlen{#2}-17}% warning length
+}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\hw@generate@logging@macros}
+% And now for the code that generates all the logging macros. Arguments:
+% \begin{enumerate}\itemsep=0pt\parskip=0pt\parsep=0pt
+% \item \marg{`package' or `class'}
+% \item \marg{prefix}
+% \item \marg{package name}
+% \item \marg{info message length}
+% \item \marg{warning message length}
+% \end{enumerate}
+% The \meta{info\dots} and \meta{warning message length} values correspond to
+% the calculation of $B$ as described above.
+%
+% First of all, if the \meta{prefix} is not specified then fall back to the \meta{package name}:
+% \begin{macrocode}
+\newcommand{\hw@generate@logging@macros}[5]{%
+ \def\@tempa{#2}\ifx\@tempa\@empty
+ \hw@generate@logging@macros@aux{#1}{#3}{#3}{#4}{#5}%
+ \else
+ \hw@generate@logging@macros@aux{#1}{#2}{#3}{#4}{#5}%
+ \fi
+}
+% \end{macrocode}
+% Finally, the main procedure. Info messages first:
+% \begin{macrocode}
+\newcommand{\hw@generate@logging@macros@aux}[5]{%
+ \expandafter\edef\csname #2@info\endcsname##1{%
+ \noexpand\HardWrap
+ {\@nameuse{hw@#1@info}{#3}}
+ {\number\numexpr#4\relax}
+ {\unexpanded\expandafter{\HardWrapSetup}}
+ {\noexpand\MessageBreak}
+ {##1}%
+ }%
+ \expandafter\edef\csname #2@info@noline\endcsname##1{%
+ \noexpand\HardWrap
+ {\@nameuse{hw@#1@info@noline}{#3}}
+ {\number\numexpr#4\relax}
+ {\unexpanded\expandafter{\HardWrapSetup}}
+ {\noexpand\MessageBreak}
+ {##1}%
+ }%
+% \end{macrocode}
+% Now warnings:
+% \begin{macrocode}
+ \expandafter\edef\csname #2@warning\endcsname##1{%
+ \noexpand\HardWrap
+ {\@nameuse{hw@#1@warning}{#3}}
+ {\number\numexpr#5\relax}
+ {\unexpanded\expandafter{\HardWrapSetup}}
+ {\noexpand\MessageBreak}
+ {##1}%
+ }%
+ \expandafter\edef\csname #2@warning@noline\endcsname##1{%
+ \noexpand\HardWrap
+ {\@nameuse{hw@#1@warning@noline}{#3}}
+ {\number\numexpr#5\relax}
+ {\unexpanded\expandafter{\HardWrapSetup}}
+ {\noexpand\MessageBreak}
+ {##1}%
+ }%
+% \end{macrocode}
+% And finally errors.
+%
+% In addition to the \meta{info} and \meta{warning} lengths,
+% the \cs{PackageError} macro allows for
+% additional text to be displayed when the user requests it. This text
+% doesn't have anything prepended to each line, so the length of this text is
+% the same as $\textit{max\_print\_line}$.
+% \begin{macrocode}
+ \expandafter\edef\csname #2@error\endcsname##1##2{%
+ \noexpand\HardWrap
+ {\xdef\noexpand\hw@tempa}
+ {\number\numexpr#5\relax}
+ {\unexpanded\expandafter{\HardWrapSetup}}
+ {\MessageBreak}
+ {\MessageBreak ##1}%
+ \noexpand\HardWrap
+ {\xdef\noexpand\hw@tempb}
+ {\the\hw@maxprintline}
+ {\unexpanded\expandafter{\HardWrapSetup}}
+ {\MessageBreak}
+ {\MessageBreak ##2}%
+ \unexpanded{%
+ \@nameuse{hw@#1@error}{#3}{\hw@tempa}{\hw@tempb}%
+ }%
+ }%
+}
+% \end{macrocode}
+% Here are our wrappers for \cs{PackageInfo} \etal, which are
+% used above to generalise the code a little. Note that these macros are
+% \cs{protected}, which allows them to be used in an expanding context
+% without a preceding \cs{noexpand}.
+% \begin{macrocode}
