%
%\begin{abstract}
%  A document class for typesetting stageplay scripts is described.
%\end{abstract}
%

%\section{Usage}

%The document class \texttt{plari} behaves like the standard document
%class \texttt{report} except that (a)~the sectioning commands
%|\section| \textit{et cetera} do not work and (b)~paragraphs are
%separated, not indented.

%In addition the following macros are defined: |\newact| starts a new
%Act, |\newscene| starts a new scene, \texttt{\bslash
%  setting\{\meta{describe setting}\}} starts a new scene and describes
%the new setting, \texttt{\bslash repl\{\meta{speaker}\}} begins a new
%line of dialogue, spoken by \meta{speaker}, and \texttt{\bslash
%  paren\{\meta{note}\}} typesets a parenthetical note.

%
%\StopEventually{\relax}
%
%\section{Implementation}
%
% First we warm up.
%    \begin{macrocode}
%<*class>
\NeedsTeXFormat{LaTeX2e}
\ProvidesClass{plari}[\filedate\space\fileversion\space\fileinfo]
\typeout{plari <\filedate:\fileversion> - typesetting stageplay scripts}
%    \end{macrocode}

% Currently we don't take any special arguments.  We just let
% \texttt{report} handle them.
%    \begin{macrocode}
\DeclareOption*{\PassOptionsToClass{\CurrentOption}{report}}
\ProcessOptions
%    \end{macrocode}

% We steal most of our code from \texttt{report.cls}.
%    \begin{macrocode}
\LoadClass{report}
%    \end{macrocode}

% Now we get to the point.  Acts are numbered individually, scenes are
% numbered within acts.  When referenced, act numbers are Roman, and
% scenes are of the form \meta{Act}:\meta{Scene}, where \meta{Scene} is
% the current scene in Arabic.
%    \begin{macrocode}
\newcounter{act}
\newcounter{scene}[act]
\renewcommand{\theact}{\Roman{act}}
\renewcommand{\thescene}{\Roman{act}:\arabic{scene}}
%    \end{macrocode}

% Acts start a new page.  Their numbers are typeset bold Huge.  Scenes
% do not start a page, and their numbers are typeset medium Large.
%    \begin{macrocode}
\newcommand{\newact}{%
  \refstepcounter{act}% 
  \newpage{\centering\bfseries\Huge--- \Roman{act} ---\par}%
  \vspace{1.5cm plus .5cm minus .5cm}%
  }
\newcommand{\newscene}{%
  \refstepcounter{scene}%
  \bigskip%
  {\centering\mdseries\Large\arabic{scene}\par}%
  \medskip%
  }
%    \end{macrocode}

% Most scenes come with a change of scenery.  The setting is typeset
% with normal size italic, but with reduced canavas.  Describing a
% setting changes scene.
%    \begin{macrocode}
\newcommand{\setting}[1]{%
  \newscene%
  \begingroup%
    \list{}{%
      \listparindent=\parindent%
      \parsep=\parskip%
      \topsep=\z@%
      \rightmargin=\leftmargin%
      }%
    \item%
    \let\item\@undefined%
    {\normalsize\itshape\mdseries#1\par}%
    \endlist%
  \endgroup%
  }
%    \end{macrocode}

% Every line in dialogue is preceded by a name.  The name is typeset
% centered, in normal size medium series small caps.  The next paragraph
% should not be indented.
%    \begin{macrocode}
\newcommand{\repl}[1]{%
  \medskip%
  {\centering\normalsize\mdseries\scshape#1\par}%
%  \smallskip%
  }
%    \end{macrocode}

% Sometimes parenthetical notes must be inserted within dialogue.  These
% notes are typeset in italic.
%    \begin{macrocode}
\newcommand{\paren}[1]{\textit{#1}}
%    \end{macrocode}

% We do not want indents. Instead, we'll have a skip between
% paragraphs.
%    \begin{macrocode}
\parindent=\z@
\parskip=\medskipamount\relax
%    \end{macrocode}

% We don't want the user to use \LaTeX\ standard sectioning.
%    \begin{macrocode}
\let\@startsection\@undefined
%    \end{macrocode} 

% We are done for good.
%    \begin{macrocode}
%</class>
%    \end{macrocode}
