% \subsubsection{Towns}
% \label{sec:impl:hex:town}
%
% Similar to above, we define a namespace and family for towns. First
% thing is the graphics style for towns. 
%
%    \begin{macrocode}
\tikzset{%
  hex/town/.style={
    scale line widths,
    solid,
    thin,
    fill=pgfstrokecolor,
    color=pgfstrokecolor},
  hex/town name/.style={
    transform shape,
    shape=rectangle,
    above right=.1,
    color=pgfstrokecolor,
    font=\sffamily\fontsize{11}{13}\selectfont}
}
%    \end{macrocode}
%
% Next is the namespace for dealing with towns.
% 
%    \begin{macrocode}
\tikzset{%
  /hex/town/.search also={/tikz},%
  /hex/town/.cd,
  pic/.store in=\hex@c@pic,
  type/.store in=\hex@c@pic,
  place/.store in=\hex@c@pos,
  location/.store in=\hex@c@pos,
  name/.store in=\hex@c@name,
  village/.style={pic=hex/town/village},
  town/.style={pic=hex/town/town},
  city/.style={pic=hex/town/city}
}
%    \end{macrocode}
%
% And some \spec{pic}tures for making the towns.
% 
%    \begin{macrocode}
\tikzset{%
  hex/town/village/.pic={\path[fill,solid,pic actions] circle(.1);},
  hex/town/town/.pic={\path[fill,solid,pic actions] circle(.2);},
  hex/town/city/.pic={%
    \path[fill,solid,pic actions] circle(.25);
    \path[draw,solid,pic actions] circle(.35);}
}
%    \end{macrocode}
%    
% \begin{Macro}{\hex@do@town}
%
%   The macro to make the towns.  This uses same tricks as above.
%   
%    \begin{macrocode}
\def\hex@c@nameparse{%
  \@ifnextchar[{\hex@c@namep@rse}{\hex@c@namep@rse[]}%]
}
\def\hex@c@namep@rse[#1]#2\endhex@c@nameparse{%
  \def\hex@c@node{node[shape=rectangle,hex/town name,#1]{#2}}}
  
\def\hex@do@town{%
  \edef\hex@c@tmp{[
    /hex/town/.cd,%
    town,%
    /tikz/hex/town,%
    /tikz/every hex town/.try,
    \hex@town]}
  \expandafter\scope\hex@c@tmp%
    \ifx\hex@c@pic\empty\else%
      \@ifundefined{hex@c@pos}{\let\hex@c@pos\empty}{}
      \@ifundefined{hex@c@name}{\let\hex@c@name\empty}{}
      \expandafter\hex@c@nameparse\hex@c@name\endhex@c@nameparse%
      \ifx\hex@c@pos\empty\def\hex@c@pos{(0,0)}\fi
      \hex@dbg{2}{Town:
        ^^J text=\hex@c@name
        ^^J pic=\hex@c@pic
        ^^J place=\hex@c@pos
        ^^J node=\hex@c@node
      }
      \filldraw \hex@c@pos pic{\hex@c@pic} \hex@c@node;
    \fi%
  \endscope%
}
%    \end{macrocode}
