% \begin{abstract}
%   This article describes a new style option that can be used with the
%   document styles that are distributed with the \LaTeX\ distributions.
%   It defines new commands to frame material with decorative frames,
%   using \textbf{dingbat} fonts.
% \end{abstract}
%

%
% \section{Introduction}
%
% When I set out to become familar with all the fonts available for
% \TeX, I came across the \textbf{dingbat} font. Only a few glyphs have
% been defined in that font, and some of them are intended to yield
% nice frames when set appropriately.
%
% I didn't want to work out the details of arranging the glyphs each
% time I needed to frame text, and hence wrote this little package to
% do the work for me.
%
% When testing this, I noticed that one of the glyphs was wrongly coded
% in the original \textbf{dingbat} distribution. Together with this
% package, a corrected version of \textbf{dingbat} is distributed.
%
% This package has no options. It requires the package |calc| by Kresten~K.
% Thorup and Frank Jensen.
%
% \section{The user interface}
% This package defines three commands, |\niceframe|, |\curlyframe| and
% |\artdecoframe|. All three take one mandatory and one optional argument.
% The mandatory argument specifies the material that is to be framed
% (anything which can go into a |\vbox|), whereas the optional argument
% specifies the final width of the frame.
%
% If the optional argument is omitted, the frame will be exactly of
% width |\textwidth|. The height of the frame is calculated from the
% natural height of the enclosed material.
%
% These frames have to be set into their own paragraphs, otherwise the
% width of the surrounding text will not be correct.
%
% The package also defines a more general macro called |\generalframe|
% to allow control over the symbols which are used to build the frame.
%
% \section{The implementation}
% \subsection{The {\sc docstrip} modules}
%
% The following modules are used in the implementation to direct
% {\sc docstrip} in generating the external files:
% \begin{center}
% \begin{tabular}{ll}
%   driver   & produce the documentation driver file \\
%   package  & produce the package file \\
%   example  & produce an example file \\
% \end{tabular}
% \end{center}
%
% \subsection{Producing the documentation}
%
% A short driver is provided that can be extracted (if necessary)
% by the {\sc docstrip} program provided with \LaTeXe.
%    \begin{macrocode}
%<*driver>
\documentclass{ltxdoc}

% dimensions from ltugboat.sty:
\setlength\textwidth{31pc} \setlength\textheight{54pc}
\setlength{\parindent}{0pt}
\setlength{\parskip}{2pt plus 1pt minus 1pt}
\setlength{\oddsidemargin}{8pc}
\setlength{\marginparwidth}{8pc}
\setlength{\topmargin}{-2.5pc}
\setlength{\headsep}{20pt}
\setlength{\columnsep}{1.5pc}
\setlength{\columnwidth}{18.75pc}

\begin{document}

\DocInput{niceframe.dtx}

\end{document}
%</driver>
%    \end{macrocode}
%
% \subsection{The example}
%
% This is just a short \LaTeX-file to test the installation. Install
% the |niceframe| package, and run |latex example.tex|.
%    \begin{macrocode}
%<*example>
\documentclass[a4paper]{article}
\usepackage{niceframe}

\begin{document}
\pagestyle{empty}

\parindent 0pt
%    \end{macrocode}
% First, a |\niceframe| that spans the whole |\textwidth|.
%    \begin{macrocode}
\niceframe{%
 \begin{center}
  May the road rise to meet you\\
  May the wind be always at your back\\
  May the sun shine warm upon your face\\
  The rain fall soft upon your fields\\
  And until we meet again\\
  May God hold you in the hollow of his hand\\
 \end{center}
 \bigskip
 \hfill The Blessing of St.~Patrick
}
\vfill
%    \end{macrocode}
% Then, a centered |\curlyframe| that is only |0.75\textwidth| wide.
%    \begin{macrocode}
\centerline{%
 \curlyframe[0.75\textwidth]{%
  \begin{center}
   \LARGE I am not flexible!\\
   Just disorganized!\\
  \end{center}
}}
\vfill
%    \end{macrocode}
% And an |\artdecoframe| for the philosophical bit.
%    \begin{macrocode}
\centerline{or is it\dots}
\vfill
\artdecoframe{%
 \begin{center}
  \LARGE I am not disorganized!\\
  Just flexible!\\
 \end{center}
}
\newpage
%    \end{macrocode}
% The following three frames are examples of |\generalframe|.
%    \begin{macrocode}
\font\border=karta15
\generalframe{\border\char'307}{\border\char'324}{\border\char'322}
             {\border\char'310}                  {\border\char'323}
             {\border\char'174}{\border\char'325}{\border\char'175}
             {This is a \texttt{generalframe}, using eight different
              characters from font \texttt{karta15} as parts of the
              framework. One might use it to point other people to
              important notes, hints and/or messages.
             }
\vfill
\font\border=umranda
\generalframe{\border\char'136}{\border\char'137}{\border\char'140}
             {\border\char'145}                  {\border\char'141}
             {\border\char'144}{\border\char'143}{\border\char'142}
             {This \texttt{generalframe} uses symbols from Alexander
              Schrell's \texttt{umranda} (his eMail is:
              alexander\_ schrell@w2.maus.de) collection.
              The material to be framed consists of quite a few lines to
              emphasize the fact that virtually anything can go
              inside a \texttt{generalframe}. Note that we are limited
              by \TeX's memory as the material to frame has to be passed
              as an argument. You can't cheat by passing a \texttt{vbox}
              that has already been set (as you might with some other
              macros) since \texttt{generalframe} has to re-set all of it.
             }
\vfill
\font\border=umrandb
\generalframe{\border\char'165}{\border\char'151}{\border\char'164}%
             {\border\char'150}                  {\border\char'150}%
             {\border\char'166}{\border\char'151}{\border\char'167}
             {Last, but not least! This \texttt{generalframe} (with
              symbols from \texttt{umrandb}) displays some math:
              $$ E = mc^2 $$
              which everyone will immediately recognize as the famous
              Einstein formula for energy-mass-equivalence.
             }
\end{document}

%    \end{macrocode}
%
% \subsection{Useful fonts}
%
% The font used for setting the frames is the \textbf{dingbat} font by
% Doug Henderson. Since the original distribution contained a wrongly
% coded char, I have included a corrected version with this package.
% Except from the code for |char("e")|, this is Doug's original file.
%
% I have also added the fonts \textbf{bbding10}, \textbf{karta15},
% \textbf{umranda} and \textbf{umrandb} for they are used in the examples.
%

%
% \subsection{The code}
%
% We begin by identifying the version of this file on the terminal and
% in the transcript fileand by loading the package |calc|.
%    \begin{macrocode}
%<*package>
\NeedsTeXFormat{LaTeX2e}[1994/06/01]
\ProvidesPackage{niceframe}[\filedate\space v\fileversion\space niceframe package (MO)]
\typeout{Package: niceframe v\fileversion\space <\filedate> (Marcus Ohlhaut)}
\RequirePackage{calc}
%    \end{macrocode}
% We then load the font used for setting the standard frames.
%    \begin{macrocode}
\font\ding dingbat scaled 1200
%    \end{macrocode}
% A few internal dimensions need to be defined and initialized.
%    \begin{macrocode}
\newlength{\nicefr@mechar}
\settowidth{\nicefr@mechar}{\ding\char'141}
\newlength{\nicefr@mewidth}
\setlength{\nicefr@mewidth}{\hsize}
\newlength{\nicefr@meheight}
\setlength{\nicefr@meheight}{\vsize}
\newlength{\@ldhsize}
\setlength{\@ldhsize}{\hsize}
%    \end{macrocode}
% \begin{macro}{\upd@ublerulefill}
% \begin{macro}{\dnd@ublerulefill}
% \begin{macro}{\ltd@ublerulefill}
% \begin{macro}{\rtd@ublerulefill}
% These internal macros define a set of leaders for each of the four
% sides of |\niceframe|. The appropriate chars are taken from the
% \textbf{dingbat} font.
%    \begin{macrocode}
\newcommand{\upd@ublerulefill}{\xleaders\hbox to 10pt
 {\hss\ding\char'142 \hss}\hfill}
\newcommand{\dnd@ublerulefill}{\xleaders\hbox to 10pt
 {\hss\ding\char'147 \hss}\hfill}
\newcommand{\ltd@ublerulefill}{\xleaders\vbox to 10pt
 {\vss\hbox{\ding\char'144}\vss}\vfill}
\newcommand{\rtd@ublerulefill}{\xleaders\vbox to 10pt
 {\vss\hbox{\ding\char'145}\vss}\vfill}
%    \end{macrocode}
% \end{macro}
% \end{macro}
% \end{macro}
% \end{macro}
% \begin{macro}{\niceframe}
% Finally, we define the user interfaces.
%    \begin{macrocode}
\newcommand{\niceframe}[2][\textwidth]{{
%    \end{macrocode}
% First, we have to set the material that is passed to |\niceframe| to
% an appropriate width. That width is the requested width of the final
% |\vbox| minus twice the size of the chars that make up the corners of
% the frame (ie.\ |\nicefr@mechar|). The set material is stored for
% further use in |\box0|.
%    \begin{macrocode}
 \setlength{\hsize}{#1 - 2\nicefr@mechar}
 \setbox0=\vbox{#2}
%    \end{macrocode}
% We then use height and depth of |\box0| to calculate the required
% height of the |\vbox| that encloses the vertical leaders.
%    \begin{macrocode}
 \setlength{\nicefr@meheight}{\ht0 + \dp0}
%    \end{macrocode}
% Similarily, we then use the width of |\box0| for enclosing the
% horizontal leaders.
%    \begin{macrocode}
 \setlength{\nicefr@mewidth}{\wd0 + 2\nicefr@mechar}
%    \end{macrocode}
% Finally, when all the relevant dimensions have been determined, the
% frame is compiled. We start with the top row (corner char, horizontal
% leader, corner char), set the middle part (vertical leader, things to
% frame, vertical leader) and finish with the bottom row (corner char,
% horizontal leader, corner char).
%    \begin{macrocode}

% \begin{macro}{\generalframe}
% Finally, I have designed a more general macro for framing.
% |\generalframe| takes nine parameters (right to the limit) and
% produces a |\vbox|. The width of this box is less than (or equal to)
% the current |\hsize|; and it consists of a border generated from the
% characters in the first eight arguments and a box which contains the
% material passed in the very last argument.
%
% The first eight parameters to |\generalframe| are used as follows:
% \begin{itemize}
% \item |#1| is the character for the top left corner,
% \item |#2| builds the top horizontal leader,
% \item |#3| is the character for the top right corner,
% \item |#4| builds the left vertical leader,
% \item |#5| builds the right vertical leader,
% \item |#6| is the character for the bottom left corner,
% \item |#7| builds the top horizontal leader,
% \item |#8| is the character for the bottom right corner,
% \end{itemize}
%
% This box is centered with respect to the frame, and there is at least
% |\fboxsep| between the frame and the enclosed material. To ensure that the
% inner box is calculated properly, all the characters for framing need
% to be of equal width and height.
%
% We first define some internal quantities. |times| holds the number
% |\hsize| \emph{div} |\fr@mecharTT| which is required in the process
% of rounding, |\fr@mecharTT| and |\fr@mecharLL| hold the width and
% height of the characters that make up the top/bottom and left/right
% parts of the frame, respectively.
%
% |\fr@mewidth| holds the final width of the frame and is always less than
% or equal to the current |\hsize|, whereas |\fr@meheight| holds the
% final height of the frame minus the heights of the top and bottom row.
%    \begin{macrocode}
\newcounter{times}
\newlength{\fr@mecharTT}
\newlength{\fr@mecharLL}
\newlength{\fr@mewidth}
\newlength{\fr@meheight}
%    \end{macrocode}
% |\generalframe| initializes |\fr@mecharTT| and |\fr@mecharLL| every
% time it is called, relying on the fact that the user specifies
% the eight border characters in such a way that |#1|, |#2|, |#3|, |#6|,
% |#7| and |#8| have the same width and |#1|, |#3|, |#4|, |#5|, |#6| and
% |#8| have the same height.
%    \begin{macrocode}
\newcommand{\generalframe}[9]{{
 \settowidth{\fr@mecharTT}{#2}
 \settoheight{\fr@mecharLL}{#4}
%    \end{macrocode}
% In order to enable a packed alignment of the horizontal leaders, we
% have to round |\fr@mewidth| to an integer multiple of |\fr@mecharTT|.
%    \begin{macrocode}
 \setcounter{times}{1 * \ratio{\hsize}{\fr@mecharTT}}
 \setlength{\fr@mewidth}{\fr@mecharTT * \value{times}}
%    \end{macrocode}
% |\fr@mewidth| is then used to calculate the |\hsize| of the innermost
% box, allowing for some horizontal space at either side. The box is set
% and stored in |\box0| for later use.
%    \begin{macrocode}
 \setlength{\hsize}{\fr@mewidth - 2\fr@mecharTT - 2\fboxsep}
 \setbox0=\vbox{#9}
%    \end{macrocode}
% We then calculate |\fr@meheight| (height plus depth of |\box0|, with
% some vertical space added) and round it to an integer multiple of
% |\fr@mecharLL|. We add one to ensure at least one character in the
% vertical leaders.
%    \begin{macrocode}
 \setlength{\fr@meheight}{\ht0 + \dp0 + 2\fboxsep}
 \setcounter{times}{1 * \ratio{\fr@meheight}{\fr@mecharLL}}
 \setcounter{times}{\value{times} + 1}
 \setlength{\fr@meheight}{\fr@mecharLL * \value{times}}
%    \end{macrocode}
% Four leaders are used to construct the main part of the frame.
%    \begin{macrocode}
 \newcommand{\up@fill}{\leaders\hbox{#2}\hfill}
 \newcommand{\lt@fill}{\leaders\vbox{\hbox{#4}}\vfill}
 \newcommand{\rt@fill}{\leaders\vbox{\hbox{#5}}\vfill}
 \newcommand{\dn@fill}{\leaders\hbox{#7}\hfill}
%    \end{macrocode}
% Finally, everthing is packed together, centered nicely.
%    \begin{macrocode}
 \vbox{%
 \hbox to\fr@mewidth{#1\up@fill#3}\nointerlineskip
 \hbox to\fr@mewidth{\vbox to\fr@meheight{\lt@fill}%
                     \hfill%
                     \vbox to\fr@meheight{\vfill\box0\vfill}%
                     \hfill%
                     \vbox to\fr@meheight{\rt@fill}%
                    }\nointerlineskip
 \hbox to\fr@mewidth{#6\dn@fill#8}\nointerlineskip
 }
