% \maketitle
% \begin{abstract}
% This document explains the usage of the \textsf{dirtytalk} package for
% \LaTeXe. It can be used to typeset \say{quotations} more comfortable. The source
% code is also explained.
% \end{abstract}
% \tableofcontents
% \clearpage{}
% \paragraph{Who should use this package?} Everybody who feels typesetting
% quotes in \LaTeX{} could be more comfortable.
% \paragraph{Who should \textit{really} use this package?} Everybody who
% typesets German texts using \verb+\glqq{}Hallo Welt\grqq{}+ for a simple
% \glqq{}Hallo Welt\grqq{} or\mdash even worse\mdash those who already started
% writing a text using the same glyphs for nested quotations and soon after find
% themselves in the embarrassing position of replacing them while being no
% \textsf{regexp} whiz.
% \section{Usage}
% \subsection{Loading}
% Put \verb+\usepackage{dirtytalk}+ in the preamble of your document.
% \subsection{Macros}\DescribeMacro{\say}
% Loaded the package you can typeset quotations by \verb+\say{hello world}+ to
% get \say{hello world}. Nested quotations are recognized as in:
% 
% \begin{tabular}{p{50.mm}p{50.mm}}
% \verb+Alice said: \say{Why did+\linebreak%
% \verb+you do that, Bob?}+%
% &Alice said: \say{Why did you do that, Bob?}\\[\parskip]
% \verb+And Bob answered: \say{+\linebreak%
% \verb+What do you mean with+\linebreak%
% \verb+\say{that}, dear Alice?}+%
% &And Bob answered: \say{What do you mean with \say{that}, dear Alice?}\\
% \end{tabular} 
% \subsection{Options}
% The package can be loaded with a couple of options to alter the glyphs being
% used. These are given in the \texttt{key=value} style.
% \begin{table}[ht]
% \begin{center}
% \begin{tabular}{lll}
% \toprule
% key               &default value  &glyph\\
% \midrule
% \texttt{left}     &\verb+``+      &``\\
% \texttt{right}    &\verb+''+      &''\\
% \texttt{leftsub}  &\verb+`+       &`\\
% \texttt{rightsub} &\verb+'+       &'\\
% \bottomrule
% \end{tabular}
% \caption{Options for the \textsf{dirtytalk} package.}
% \end{center}
% \end{table}
% 
% So my fellow German citizens might load the package with
% \begin{verbatim}
% \usepackage[%
%   left     = \glqq,%
%   right    = \grqq,%
%   leftsub  = \glq,%
%   rightsub = \grq%
% ]{dirtytalk}
% \end{verbatim}
% 
% to get German glyphs. Pleas note that the package does \textit{not} check your
% document language to alter the symbols used. It depends on you as the author to
% specify those you want.
% 
% Happy \LaTeX ing!
% 
% \section{Source Code Documentation}
% This section shows and explains the entire code of the package. (It is
% intended for \LaTeX{} programmers only.)
% \subsection{Identification}
%    \begin{macrocode}
\NeedsTeXFormat{LaTeX2e}
\ProvidesPackage{dirtytalk}[2010/11/21 A package making "quoting" easier]
%    \end{macrocode}
% \subsection{Preliminary Declarations}
% We use options from the \texttt{key=value} type so we need to load a package
% supporting this:
%    \begin{macrocode}
\RequirePackage{kvoptions}
%    \end{macrocode}
% Define the glyphs that will enclose the phrases. We initially define them for
% English which will probably be the most requested standard. If the package is
% loaded with options, the following macros will be redefined.
% 
% \begin{macro}{\dirtytalk@lqq}
% Outer opening (left) quotation mark glyph.
%    \begin{macrocode}
\newcommand{\dirtytalk@lqq}{``}
%    \end{macrocode}
% \end{macro}
% \begin{macro}{\dirtytalk@rqq}
% Outer closing (right) quotation mark glyph.
%    \begin{macrocode}
\newcommand{\dirtytalk@rqq}{''}
%    \end{macrocode}
% \end{macro}
% \begin{macro}{\dirtytalk@lq}
% Inner opening (left) quotation mark glyph.
%    \begin{macrocode}
\newcommand{\dirtytalk@lq}{`}
%    \end{macrocode}
% \end{macro}
% \begin{macro}{\dirtytalk@rq}
% Inner closing (right) quotation mark glyph.
%    \begin{macrocode}
\newcommand{\dirtytalk@rq}{'}
%    \end{macrocode}
% \end{macro}
% \subsection{Options}
% We allow the author to specify own quotation mark glyphs instead of those
% defined above by passing them as options.
%    \begin{macrocode}
\DeclareStringOption{left}
\DeclareStringOption{right}
\DeclareStringOption{leftsub}
\DeclareStringOption{rightsub}
%    \end{macrocode}
%    \begin{macrocode}
\ProcessKeyvalOptions*
%    \end{macrocode}
% \subsection{More Declarations}
% After processing the options (in case of the \textsf{kvoptions}' string
% options that means a macro has been defined holding the key value) we check if
% they are empty and, if not so, redefine the default glyphs. For this task we
% need the \textsf{ifthen} package.
%    \begin{macrocode}
\RequirePackage{ifthen}
%    \end{macrocode}
%    \begin{macrocode}
\ifthenelse%
  {\equal{\dirtytalk@left}{}}%
  {}%
  {\renewcommand{\dirtytalk@lqq}{\dirtytalk@left}}
%    \end{macrocode}
%    \begin{macrocode}
\ifthenelse%
  {\equal{\dirtytalk@right}{}}%
  {}%
  {\renewcommand{\dirtytalk@rqq}{\dirtytalk@right}}
%    \end{macrocode}
%    \begin{macrocode}
\ifthenelse%
  {\equal{\dirtytalk@leftsub}{}}%
  {}%
  {\renewcommand{\dirtytalk@lq}{\dirtytalk@leftsub}}
%    \end{macrocode}
%    \begin{macrocode}
\ifthenelse%
  {\equal{\dirtytalk@rightsub}{}}%
  {}%
  {\renewcommand{\dirtytalk@rq}{\dirtytalk@rightsub}}
%    \end{macrocode}
% And we define a counter that represents the depth to which a quotation is
% nested. However, we will only distinguish between \say{not nested} and
% \say{nested} (\texttt{dirtytalk@qdepth} $>$ 1). Since there is no convention for
% sub-sub-quotes. (At least, I don't know any.)
%    \begin{macrocode}
\newcounter{dirtytalk@qdepth}
%    \end{macrocode}
% Using this counter, we can now determine which glyph we have to use.
% \begin{macro}{\dirtytalk@lsymb}
% We define one macro for opening quotes:
%    \begin{macrocode}
\newcommand%
  {\dirtytalk@lsymb}%
  {\ifthenelse%
    {\value{dirtytalk@qdepth}>1}%
    {\dirtytalk@lq}%
    {\dirtytalk@lqq}%
  }%
%    \end{macrocode}
% \end{macro}
% \begin{macro}{\dirtytalk@rsymb}
% And one for closing quotes:
%    \begin{macrocode}
\newcommand{\dirtytalk@rsymb}%
  {\ifthenelse%
    {\value{dirtytalk@qdepth}>1}%
    {\dirtytalk@rq}%
    {\dirtytalk@rqq}%
  }
%    \end{macrocode}
% \end{macro}
% \begin{macro}{\say}
% And so finally we can declare the only macro this package provides to the
% author. On opening quotes we increment the \texttt{dirtytalk@qdepth} counter and
% decrement it on closing ones. The appropriate glyph is obtained form
% \verb+\dirtytalk@lsymb+ or \verb+\dirtytalk@rsymb+ respectively.
%    \begin{macrocode}
\providecommand{\say}[1]%
  {%
    \addtocounter{dirtytalk@qdepth}{1}%
    \dirtytalk@lsymb%
    #1%
    \dirtytalk@rsymb%
    \addtocounter{dirtytalk@qdepth}{-1}%
  }
%    \end{macrocode}
% \end{macro}
