\title{Various chapter styles for the memoir class\thanks{\MyFileVersion}}
\author{Lars Madsen\thanks{Email: \protect\url{daleif@imf.au.dk}}}
\maketitle

The main idea behind this document is to demonstrate various either
contributed or inspired chapter styles for the memoir class.

If you have style you would like to contribute a style/implementation,
please send it with a minimal example to \url{daleif+memoir@imf.au.dk}
and I will include it into this document.

\bigskip
\starbreak

\noindent The visual examples you will find later in this document
have all been made using external documents and included as images
(eps or pdf). As such, all images are scaled to have the same width as
the  text in this document, therefore some images are scaled down.

Also, please do not trust the spacing between the chapter title and
the start of the following text. This \verb+\afterchapskip+-spacing is
silently reduced (to \verb+\onelineskip+) in order to save space, the
same goes for \verb+\beforechapskip+.

\starbreak

In any good chapter style design one should have given a thought at
both the normal numbered style as well as the unnumbered
style. Therefore the example text features both a numbered chapter and
an unnumbered. (I have relaxed \verb+\clearforchapter+ in order to
have both on the same side.)

The sample text used is
\VerbatimInput[
label={chapterexample.tex},
fontsize=\small
]{chapterexample.tex}

\starbreak

If you want to use one of the styles presented in this document, 
then there is no need to start retyping it all your self. Simply
download the source for this document (\texttt{\jobname.tex}) from
\url{http://mirror.ctan.org/info/MemoirChapStyles/}. Run it
once through \LaTeX, then you will 
get a file called \Arg{Name of style}\texttt{-style.tex}, which is the
source code for example displaying that particular style. Then just
copy the code from there.

Please note that in the code you will find stuff like
\begin{Verbatim}
\let\STARTCODE\relax 
\let\STOPCODE\relax 
\STARTCODE
...
\STOPCODE  
\end{Verbatim}
This code can just be removed, it is used by this document as an easy
manner to include certain parts of a given source code.

\section*{Acknowledgement}

Acknowledgement goes (of course) to Peter Wilson for creating the
memoir class in the first place. But also to the people who
contributed with styles or comments: Danie Els, David Chadd, Pluton
(name used on \textsc{ctt}), Erik Quaeghebeur, Donald Arseneau plus
the those who posted memoir chapter styles on news groups, I hope it
is okay that I include them here.




\section*{TODO}
\label{sec:todo}

Have a look at the chapter styles offered by \texttt{fncychap} and
\texttt{titlesec}.

\chapter{A little background}
\label{cha:little-background}

As you might already know the memoir class includes a feature to
switch the look and feel of a chapter title on a chapter to chapter
basis. This is achieved by using \verb+\chapterstyle+\Arg*{style}. The
most extreme use of this is seen in \emph{The Memoir class For
  Configurable Typesetting -- User Guide} by Peter Wilson, also know
as the \emph{Memoir manual}, \cite{memman}.


In general, \LaTeX\ classes use \verb+\@makechapterhead+ to print a
chapter title specified my \verb|chapter|, and
\verb+\@makeschapterhead+ for \verb+\chapter*+. In memoir Peter Wilson
made these two macros a bit more flexible than usual. The idea is
that for numbered chapters (i.e. \verb+\chapter+ and
$\texttt{secnumdepth}\geq\nobreak 0$) one should think of the chapter title as
build by:
\begin{Verbatim}
\chapterheadstart
\printchaptername \chapternamenum \printchapternum
\afterchapternum
\printchaptertitle{The title}  
\afterchaptertitle
\end{Verbatim}
For unnumbered (i.e. \verb+\chapter*+ and \verb+\chapter+ width
$\texttt{secnumdepth}<0$): 
\begin{Verbatim}
\chapterheadstart
\printchapternonum
\printchaptertitle{The title}
\afterchaptertitle  
\end{Verbatim}
Note that \verb+\printchaptertitle+ is the only macro that takes an
argument. At the start of every memoir chapter style these macros are
initialised to
\begin{Verbatim}
\renewcommand\chapterheadstart{\vspace*{\beforechapskip}}
\renewcommand\printchaptername{\chapnamefont \@chapapp}
\renewcommand\chapternamenum{\space}
\renewcommand\printchapternum{\chapnumfont \thechapter}
\renewcommand\afterchapternum{\par\nobreak\vskip \midchapskip}
\renewcommand\printchapternonum{}
\renewcommand\printchaptertitle[1]{\chaptitlefont #1}
\renewcommand\afterchaptertitle{\par\nobreak\vskip \afterchapskip}
\end{Verbatim}
So one just have to change the ones one need. There are a few other
macros that are nice to know the meaning of. Remember that these are
\emph{not} reset at the start of a new chapter style.
\begingroup
\renewcommand\descriptionlabel[1]{\hspace\labelsep\cs{#1}}
\begin{description}\firmlist
\item[beforechapskip] length, self explanatory,usually set using
  \verb+\chapterheadstart+, default 50pt
\item[midchapskip] length, distance between the chapter name / number and the
title, usually set using \verb+\afterchapternum+, default 20pt
\item[afterchapskip] length, distance between the chapter title and
  the following text, usually set using \verb+\afterchaptertitle+,
  default 40pt
\item[chapnamefont] the font setting used for \emph{Chapter} or
  similar, default \verb+\normalfont\huge\bfseries+
\item[chapnumfont] same for the chapter number, default
  \verb+\normalfont\huge\bfseries+
\item[chaptitlefont] same for the chapter title, default
  \verb+\normalfont\Huge\bfseries+ 
\end{description}
\endgroup
\noindent One might ask what \verb+\printchapternonum+ is good for
when it is always initialised to nothing. Well if a design need to one
could use it to insert a phantom width as wide as the chapter name
plus number would have been. If on the other hand one is creating a
style where the chapter name and number is actually typeset using
\verb+\printchaptertitle+ (like a framed one) then one could first
define a new if construction, say, \verb+\ifNoChapNum+ and then let
\verb+\printchapternonum+ set this to true and so on.

In memoir a new chapter style is defined as
\begin{syntax}
\cs{makechapterstyle}\Arg*{name}\texttt{\{}  
\Arg{code}
\texttt{\}}
\end{syntax}
Where \Arg{code} is redefinitions of the macros mentioned
above. (Remember that if you redefine\linebreak \verb+\printchaptertitle+ then
you have to use \texttt{\#\#1} to represent the title.)
Activating a given style is done by simply issuing
\begin{syntax}
  \cs{chapterstyle}\Arg*{name}
\end{syntax}
By the way, if you happen to like a given style but wanted to, say,
add color to the chapter title, you could just refine
\verb+\chaptitlefont+ after you have issued \verb+\chapterstyle+. (Even
simpler to just use \verb+\addtodef\chaptitlefont{}{\color{nicered}}+.)

As a simple example, here is the code for the \texttt{section} chapter
style
\begin{Verbatim}[label={Source code for the \textsf{section} chapter style}]
\makechapterstyle{section}{%
  \renewcommand{\printchaptername}{}
  \renewcommand{\chapternamenum}{}
  \renewcommand{\chapnumfont}{\normalfont\Huge\bfseries}
  \renewcommand{\printchapternum}{\chapnumfont \thechapter\space}
  \renewcommand{\afterchapternum}{}
}
\end{Verbatim}

This next style is inspired by a mail I recieved from Erik
Quaeghebeur. It took me a little while to actually get this working as
I wanted it to, partly because apparently there is a small issue
regarding \cs{thispagestyle} and \cs{pagestyle} as to which
\cs{chaptermark} gets used (I got around this by using the
\texttt{afterpage} package). This style is designed to be used with
\texttt{openleft} (i.e. chapters starting on even pages). And since
the design uses pagestyles, we need to show several seperate pages.

\chapter{Vincent Zoonekynd}
\label{sec:vincent-zoonekynd}

Some time ago Vincent Zoonekynd published a long list of general
chapter styles for \LaTeX, see
\url{http://zoonek.free.fr/LaTeX/LaTeX_samples_chapter/0.html}. 
In this section we implement several of these styles. Special thanks
to Danie Els for the BlueBox style (aka VZ39).

The styles are named after Vincent Zoonekynd (VZ) and the number on
the mentioned page.
\begin{showchapterstyle}{VZ14}
\makeatletter
\newcommand\thickhrulefill{\leavevmode \leaders \hrule height 1ex \hfill \kern \z@}
\setlength\midchapskip{10pt}
\makechapterstyle{VZ14}{

  \renewcommand\chapnamefont{\Large\scshape}
  \renewcommand\printchapternum{%

  \renewcommand\printchapternonum{%

  \renewcommand\afterchaptertitle{%

}
\makeatother
\end{showchapterstyle}
Though I believe this style would look better without the lines. 

Variation over VZ21. Note the use of two different tabulars depending
upon the length of the title. Also note that we use the build-in
booktabs rules, and note that the thickness of these rules can be
individually adjusted. 
\begin{showchapterstyle}{VZ21}
\usepackage{calc,fourier}
\usepackage[T1]{fontenc}
\makeatletter
\setlength\midchapskip{7pt}
\makechapterstyle{VZ21}{
  \renewcommand\chapnamefont{\Large\scshape}
  \renewcommand\chapnumfont{\Large\scshape\centering}
  \renewcommand\chaptitlefont{\huge\bfseries\centering}
  \renewcommand\printchaptertitle[1]{%
    \setlength\tabcolsep{7pt}% used as indentation on both sides
    \settowidth\@tempdimc{\chaptitlefont ##1}%
    \setlength\@tempdimc{\textwidth-\@tempdimc-2\tabcolsep}%
    \chaptitlefont
    \ifdim\@tempdimc > 0pt\relax% one line
    \begin{tabular}{c}
      \toprule  ##1\\ \bottomrule
    \end{tabular}
    \else% two+ lines
    \begin{tabular}{%
        >{\chaptitlefont\arraybackslash}p{\textwidth-2\tabcolsep}}
      \toprule ##1\\ \bottomrule
    \end{tabular}
    \fi
  }
}
\makeatother
\end{showchapterstyle}
Next up is VZ23.
\begin{showchapterstyle}{VZ23}
\setlength\midchapskip{10pt}
\makechapterstyle{VZ23}{
  \renewcommand\chapternamenum{}
  \renewcommand\printchaptername{}
  \renewcommand\chapnumfont{\Huge\bfseries\centering}
  \renewcommand\chaptitlefont{\Huge\scshape\centering}
  \renewcommand\afterchapternum{%
    \par\nobreak\vskip\midchapskip\hrule\vskip\midchapskip}
  \renewcommand\printchapternonum{%
    \vphantom{\chapnumfont \thechapter}
    \par\nobreak\vskip\midchapskip\hrule\vskip\midchapskip}
}  
\end{showchapterstyle}
A variation over VZ34 (in the original the first cell in the tabular
adjusts to the width of the chapter number, here it does not).
\begin{showchapterstyle}{VZ34}
\usepackage{calc}
\newif\ifNoChapNumber
\makeatletter
\makechapterstyle{VZ34}{
  \renewcommand\chapternamenum{}
