% \subsection{\themename parent theme}
%
% The primary job of this package is to load the component sub-packages of the
% \themename theme and route the theme options accordingly. It also
% provides some custom commands and environments for the user.
%
% \subsubsection{Package dependencies}
%
%    \begin{macrocode}
\RequirePackage{pgfopts}
\RequirePackage{tikz}
%    \end{macrocode}
%
%\subsubsection{Options}
%
% Most options are passed off to the component sub-packages.
%    \begin{macrocode}
\pgfkeys{/trigon/.cd,
  .search also={
    /trigon/inner,
    /trigon/outer,
    /trigon/color,
    /trigon/font
  }
}
%    \end{macrocode}
%
% \begin{macro}{titleformat plain}
% Controls the formatting of the text on standout ``plain'' frames.
%    \begin{macrocode}
\pgfkeys{
  /trigon/titleformat plain/.cd,
  .is choice,
  regular/.code={%
    \let\trigon@plaintitleformat\@empty%
    \setbeamerfont{standout}{shape=\normalfont}%
  },
  smallcaps/.code={%
    \let\trigon@plaintitleformat\@empty%
    \setbeamerfont{standout}{shape=\scshape}%
  },
  allsmallcaps/.code={%
    \let\trigon@plaintitleformat\MakeLowercase%
    \setbeamerfont{standout}{shape=\scshape}%
    \PackageWarning{beamerthemetrigon}{%
      Be aware that titleformat plain=allsmallcaps can lead to problems%
    }
  },
  allcaps/.code={%
    \let\trigon@plaintitleformat\MakeUppercase%
    \setbeamerfont{standout}{shape=\normalfont}%
    \PackageWarning{beamerthemetrigon}{%
      Be aware that titleformat plain=allcaps can lead to problems%
    }
  },
}
%    \end{macrocode}
% \end{macro}
%
% \begin{macro}{titleformat}
% Sets a standard format for titles, subtitles, section titles, frame titles,
% and the text on standout ``plain'' frames.
%    \begin{macrocode}
\pgfkeys{
  /trigon/titleformat/.code=\pgfkeysalso{
    font/titleformat title=#1,
    font/titleformat subtitle=#1,
    font/titleformat section=#1,
    font/titleformat frame=#1,
    titleformat plain=#1,
  }
}
%    \end{macrocode}
% \end{macro}
%
% \begin{macro}{usesourcefonts}
% Select whereas the Source Sans Pro font is being loaded automatically or not.
%    \begin{macrocode}
\newif\if@trigon@usesourcefonts
\pgfkeys{/trigon/.cd,
  usesourcefonts/.is if=@trigon@usesourcefonts,
  usesourcefonts=true,
}
%    \end{macrocode}
% \end{macro}
%
%
% \subsubsection{Component sub-packages}
%
% Having processed the options, we can now load the component sub-packages of
% the theme.
%
%    \begin{macrocode}
\useinnertheme{trigon}
\useoutertheme{trigon}
\usecolortheme{trigon}
\usefonttheme{trigon}
%    \end{macrocode}
%
%
% \subsubsection{Custom commands}
%
% The parent theme defines custom commands as their proper usage may depend
% on multiple sub-packages.
%
% \begin{macro}{\metroset}
% Allows the user to change options midway through a presentation.
%    \begin{macrocode}
\newcommand{\trigonset}[1]{\pgfkeys{/trigon/.cd,#1}}
%    \end{macrocode}
% \end{macro}
%
%
% \subsubsection{Process package options}
%
%    \begin{macrocode}
\ProcessOptionsBeamer
\ProcessPgfOptions{/trigon}
\if@trigon@usesourcefonts%
  \RequirePackage[default,t1,semibold]{sourcesanspro}
\fi
%    \end{macrocode}

% \iffalse
