D.4.1 titleformat title

  regular/.code={%
      \let\moloch@titleformat\@empty%
      \setbeamerfont{title}{shape=\normalfont}%

    },
  allsmallcaps/.code={%
      \let\moloch@titleformat\lowercase%
      \setbeamerfont{title}{shape=\scshape}%
      \PackageNote{beamerthememoloch}{%
        Be aware that titleformat title=allsmallcaps can
        lead to problems}
    },
  allcaps/.code={%
      \let\moloch@titleformat\uppercase%
      \setbeamerfont{title}{shape=\normalfont}
      \PackageNote{beamerthememoloch}{%

      }
    },
}

    },
  smallcaps/.code={%
      \let\moloch@subtitleformat\@empty%
      \setbeamerfont{subtitle}{shape=\scshape}%
    },
  allsmallcaps/.code={%
      \let\moloch@subtitleformat\MakeLowercase%
      \setbeamerfont{subtitle}{shape=\scshape}%
      \PackageNote{beamerthememoloch}{%
        Be aware that titleformat subtitle=allsmallcaps
        can lead to problems}
    },
  allcaps/.code={%
      \let\moloch@subtitleformat\MakeUppercase%
      \setbeamerfont{subtitle}{shape=\normalfont}%
      \PackageNote{beamerthememoloch}{%
        Be aware that titleformat subtitle=allcaps can
        lead to problems}
    },
}

D.4.3 titleformat section

\pgfkeys{
  /moloch/font/titleformat section/.cd,
  .is choice,
  regular/.code={%
      \let\moloch@sectiontitleformat\@empty%
      \setbeamerfont{section title}{shape=\normalfont}%
    },
  smallcaps/.code={%
      \let\moloch@sectiontitleformat\@empty%
      \setbeamerfont{section title}{shape=\scshape}%
    },
  allsmallcaps/.code={%
      \let\moloch@sectiontitleformat\MakeLowercase%
      \setbeamerfont{section title}{shape=\scshape}%
      \PackageNote{beamerthememoloch}{%
        Be aware that titleformat section=allsmallcaps
        can lead to problems}
    },
  allcaps/.code={%
      \let\moloch@sectiontitleformat\MakeUppercase%
      \setbeamerfont{section title}{shape=\normalfont}%
      \PackageNote{beamerthememoloch}{%
        Be aware that titleformat section=allcaps
        can lead to problems}
    },
}

D.4.4 frametitleformat

Control the format of the frame title.

\pgfkeys{
  /moloch/font/titleformat frame/.cd,
  .is choice,
  regular/.code={%
      \let\moloch@frametitleformat\@empty%
      \setbeamerfont{frametitle}{shape=\normalfont}%
    },
  smallcaps/.code={%
      \let\moloch@frametitleformat\@empty%
      \setbeamerfont{frametitle}{shape=\scshape}%
    },
  allsmallcaps/.code={%
      \let\moloch@frametitleformat\MakeLowercase%
      \setbeamerfont{frametitle}{shape=\scshape}%
      \PackageNote{beamerthememoloch}{%
        Be aware that titleformat frame=allsmallcaps
        can lead to problems}
    },
  allcaps/.code={%
      \let\moloch@frametitleformat\MakeUppercase%
      \setbeamerfont{frametitle}{shape=\normalfont}
      \PackageNote{beamerthememoloch}{%
        Be aware that titleformat frame=allcaps can lead to problems%
      }
    },
}

D.4.5 titleformat aliases

Allows titleformat title et al. to be used in the \usetheme declaration, where LaTeX automatically removes all spaces.

\pgfkeys{
  /moloch/font/.cd,
  titleformattitle/.code=\pgfkeysalso{titleformat title=#1},
  titleformatsubtitle/.code=\pgfkeysalso{titleformat subtitle=#1},
  titleformatsection/.code=\pgfkeysalso{titleformat section=#1},
  titleformatframe/.code=\pgfkeysalso{titleformat frame=#1},
}

D.4.6 \moloch@font@setdefaults

Sets default values for font theme options.

\newcommand{\moloch@font@setdefaults}{
  \pgfkeys{/moloch/font/.cd,
    titleformat title=regular,
    titleformat subtitle=regular,
    titleformat section=regular,
    titleformat frame=regular,
  }
}

We first define hooks to change the case format of the titles.

\def\moloch@titleformat#1{#1}
\def\moloch@subtitleformat#1{#1}
\def\moloch@sectiontitleformat#1{#1}
\def\moloch@frametitleformat#1{#1}

To make the uppercase and lowercase macros work in the title, subtitle, etc., we have to patch the appropriate beamer commands that set their values. This solution was suggested by Enrico Gregorio in an answer to this StackExchange question.

D.5 Process Package Options
