%
% \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{etoolbox}
\RequirePackage{pgfopts}
% \end{macrocode}
%
%
%
% \subsubsection{Options}
%
% Most options are passed off to the component sub-packages.
%
% \begin{macrocode}
\pgfkeys{/metropolis/.cd,
.search also={
/metropolis/inner,
/metropolis/outer,
/metropolis/color,
/metropolis/font,
}
}
% \end{macrocode}
%
% \begin{macro}{titleformat plain}
% Controls the formatting of the text on standout ``plain'' frames.
% \begin{macrocode}
\pgfkeys{
/metropolis/titleformat plain/.cd,
.is choice,
regular/.code={%
\let\metropolis@plaintitleformat\@empty%
\setbeamerfont{standout}{shape=\normalfont}%
},
smallcaps/.code={%
\let\metropolis@plaintitleformat\@empty%
\setbeamerfont{standout}{shape=\scshape}%
},
allsmallcaps/.code={%
\let\metropolis@plaintitleformat\MakeLowercase%
\setbeamerfont{standout}{shape=\scshape}%
\PackageWarning{beamerthememetropolis}{%
Be aware that titleformat plain=allsmallcaps can lead to problems%
}
},
allcaps/.code={%
\let\metropolis@plaintitleformat\MakeUppercase%
\setbeamerfont{standout}{shape=\normalfont}%
\PackageWarning{beamerthememetropolis}{%
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{
/metropolis/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}
%
% For backwards compatibility with earlier betas of the theme, we implement
% deprecated option names as aliases to the corresponding |key=value| options.
%
% \begin{macrocode}
\pgfkeys{/metropolis/.cd,
usetitleprogressbar/.code=\pgfkeysalso{outer/progressbar=frametitle},
noslidenumbers/.code=\pgfkeysalso{outer/numbering=none},
usetotalslideindicator/.code=\pgfkeysalso{outer/numbering=fraction},
nosectionslide/.code=\pgfkeysalso{inner/sectionpage=none},
darkcolors/.code=\pgfkeysalso{color/background=dark},
blockbg/.code=\pgfkeysalso{color/block=fill, inner/block=fill},
}
% \end{macrocode}
%
% Set default values for options.
%
% \begin{macrocode}
\newcommand{\metropolis@setdefaults}{
\pgfkeys{/metropolis/.cd,
titleformat plain=regular,
}
}
% \end{macrocode}
%
%
%
% \subsubsection{Component sub-packages}
%
% Having processed the options, we can now load the component sub-packages of
% the theme.
%
% \begin{macrocode}
\useinnertheme{metropolis}
\useoutertheme{metropolis}
\usecolortheme{metropolis}
\usefonttheme{metropolis}
% \end{macrocode}
%
% The |tol| theme for |pgfplots| is only loaded if |pgfplots| is used.
%
% \begin{macrocode}
\AtEndPreamble{%
\@ifpackageloaded{pgfplots}{%
\RequirePackage{pgfplotsthemetol}
}{}
}
% \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{\metroset}[1]{\pgfkeys{/metropolis/.cd,#1}}
% \end{macrocode}
% \end{macro}
%
% \begin{macro}{\plain}
% Creates a plain frame with dark background, suitable for displaying images
% or a few words. The format of the text can be set with the
% |titleformat plain| option.
% \begin{macrocode}
\def\metropolis@plaintitleformat#1{#1}
\newcommand{\plain}[2][]{%
\PackageWarning{beamerthememetropolis}{%
The syntax `\plain' may be deprecated in a future version of Metropolis.
Please use a frame with [standout] instead.
}
\begin{frame}[standout]{#1}
\metropolis@plaintitleformat{#2}
\end{frame}
}
% \end{macrocode}
% \end{macro}
%
% \begin{macro}{\mreducelistspacing}
% \begin{macrocode}
\newcommand{\mreducelistspacing}{\vspace{-\topsep}}
% \end{macrocode}
% \end{macro}
%
%
%
% \subsubsection{Process package options}
%
% \begin{macrocode}
\metropolis@setdefaults
\ProcessPgfOptions{/metropolis}
% \end{macrocode}
%
% \iffalse
%</package>
