\section{Features}
\subsection{How to use}

\begin{frame}[fragile,stretch=3]{How to use}
  \begin{itemize}
    \item Copy the contents of the \texttt{sty/} directory into your project.
  
    \item If you downloaded this template from GitHub, you also need to \href{https://intranet.hj.se/intranet/en/service-and-support/marketing-and-communication/graphic-profile/logotypes.html}{{\small\faExternalLink*}~download the JU~logotypes} from the intranet and extract the PNG~versions into the \texttt{sty/img/} directory.
  
    \item You can then use this theme by including:\medskip
  
    \begin{minted}{latex}
    \usetheme[maincolor=purple]{metropolis-ju}
    \end{minted}
    
    \medskip
    \item \alert{Use LuaLaTeX for best results.}
  \end{itemize}
\end{frame}

\subsection{Theme options}

{
\metroset{maincolor=grey}
\begin{frame}[fragile,stretch=3]{Options: Color theme}

    \begin{itemize}
    \item The \texttt{maincolor} option sets the background colors of title/standout frames as well as the      headline.\medskip
    
    It can be either \colorbox{juPurple}{\textcolor{white}{\texttt{purple}}} (default) or \colorbox{juGrey}{\textcolor{white}{\texttt{grey{\vphantom l}}}}.

    \item This slide shows what the theme looks like with \texttt{maincolor=grey}.
  
    \item You can change colors in the middle of your presentation via:\medskip

          \mint{latex}|   \metroset{maincolor=grey}|
    \end{itemize}
    
    \medskip
    \textit{Note: For changing the font theme, see the later \hyperlink{selectfonts}{\textcolor{juDarkBlue}{``Fonts'' section.}}}
\end{frame}
}

\begin{frame}[stretch]{Options: Logotypes}
  \begin{itemize}
    \item The \texttt{titlelogo} option sets the logotype to put on the title frame.  It can be either:
    \begin{itemize}
        \item \texttt{none}: no logo
        \item \texttt{ju}: JU's main logotype \alert{\bf (this is the default)}
        \item \texttt{jth}: JTH's logotype
    \end{itemize}
    \item The \texttt{headlogo} option does the same thing, but for the smaller logotype in the headline.
    \item Logotypes from the other schools aren't currently included, but could of course also be added.
  \end{itemize}
\end{frame}

{\metroset{maincolor=grey}
\begin{frame}[fragile,stretch]{Aside --- Logotypes in Other Places}

The logotypes can be inserted with the following commands:

\begin{center}
\begin{tabular}{lc}
    \mintinline{latex}{\juLogo} & \begin{minipage}{0.3\textwidth}\centering\juLogo[height=5ex]{}\end{minipage} \\[2ex]
    \mintinline{latex}{\juLogoSmall} & \begin{minipage}{0.3\textwidth}\centering\juLogoSmall[height=2.5ex]{}\end{minipage} \\
\end{tabular}
\end{center}

Scaling options can be given as an argument, e.g.\ \mintinline{latex}{\juLogo[height=2cm]}.

\begin{itemize}
    \item To get the white versions of the logos, append \texttt{W} to the command; e.g. \mintinline{latex}{\juLogoSmallW}.
    \item To get the JTH logos, use \mintinline{latex}{\jthLogo...} equivalents.
\end{itemize}

\end{frame}
}

\begin{frame}{Options: Footer and Section Pages}
  In addition to all the options the standard \textsc{Metropolis} theme provides, I added the following options, implementing features from \textsc{colorful-dream}:

  \begin{itemize}
    \item \texttt{footer=crumbs} will put the ``breadcrumbs'' line in the footer with the current section/subsection titles.
    \item \texttt{sectionpage=numbered} will produce the section pages with numbered circles.
    \item \texttt{subsectionpage=numbered} will do the same thing for subsections \textit{(not enabled in this presentation)}.
  \end{itemize}
\end{frame}

\subsection{Layout}

\begin{frame}[stretch=5]{Layout: Typesetting the frame title}
  The frame title on the \alert{colored bar} at the top of the slide comes from the \textsc{Metropolis} theme.

  This can look nice, but \alert{does not match JU's own presentation templates.}
  
  However, you can also get something closer to JU's official style\ldots
\end{frame}

\begin{frame}[fragile,stretch=1.5]
  \juHeading{Typesetting the frame title}
  
  A frame \emph{without} a title will look like this.
  
  The heavy, all-uppercase heading can be produced via the command:
  
    \mint{latex}|   \juHeading{A title in JU style}|

  The automatic upper-casing might cause some issues with certain symbols or commands inside the heading.  If that's the case, you can use this version without the upper-casing magic:

    \mint{latex}|   \juHeadingCased{A HEADING WITH ``QUOTES''}|
\end{frame}

\begin{frame}[fragile,stretch=3.5]{Layout: Spacing}
It's nice to have less text per slide!

\begin{itemize}
    \item Frames now have an additional \alert{\texttt{stretch}} key with a stretch factor as an optional value (defaults to~\texttt{2}).  It will \alert{increase spacing} between paragraphs and list items.

    \item The idea is to make it easier to stretch slide contents, \emph{without} littering the code with \mintinline{latex}{\vspace{...}} commands everywhere.

    \item This slide uses \texttt{stretch=3.5}.
\end{itemize}

\end{frame}

\begin{frame}[fragile]{Layout: Two-column layout}
To quickly get a two-column layout, you can use:\medskip
    
    \mint{latex}|\twocol{First column here.}{Second column here.}|
    \medskip
    
    By default, this will make both columns equally wide, namely \mintinline{latex}{0.475\linewidth}.
    
    \bigskip
    \twocol[0.3]{An optional argument can be used to specify a different factor for the first column.  Here, I used \texttt{0.3}.}{The second column will automatically expand so that the two columns combined take up \mintinline{latex}{0.95\linewidth}. \textit{(This is less than~1 so that there is some padding between them.)}}
\end{frame}


\section{Colors}

\begin{frame}{Colors}
  This theme defines the following colors that you can use anywhere in your presentation. They are all based on the color values in JU's official Graphic Manual.
  \bigskip
  
  \centering
  \begin{tabular}{ >{\raggedleft\arraybackslash} m{3cm} m{1cm}  >{\raggedleft\arraybackslash} m{3cm} m{1cm} }
    \tt juPurple & \colorbox{juPurple}{\makebox(14,14){~}} &  \tt juYellow & \colorbox{juYellow}{\makebox(14,14){~}} \\
    \tt juGrey & \colorbox{juGrey}{\makebox(14,14){~}} & \tt juTurquoise & \colorbox{juTurquoise}{\makebox(14,14){~}} \\
    &&
    \tt juDarkBlue & \colorbox{juDarkBlue}{\makebox(14,14){~}} \\
    &&
    \tt juBeige & \colorbox{juBeige}{\makebox(14,14){~}} \\
  \end{tabular}
\end{frame}

\subsection{Tints}

\begin{frame}{Colors}
  Different color tints are also defined.
  \bigskip
  
  \centering
 \begin{tabular}{ >{\raggedleft\arraybackslash} m{3.5cm} m{1cm}  >{\raggedleft\arraybackslash} m{3.5cm} m{1cm} }
    \tt juPurpleDarker & \colorbox{juPurpleDarker}{\makebox(14,14){~}} & & \\
    \tt juPurpleFade1 & \colorbox{juPurpleFade1}{\makebox(14,14){~}} & \tt juGreyFade1 & \colorbox{juGreyFade1}{\makebox(14,14){~}} \\
    \tt juPurpleFade2 & \colorbox{juPurpleFade2}{\makebox(14,14){~}} & \tt juGreyFade2 & \colorbox{juGreyFade2}{\makebox(14,14){~}} \\
    \tt juPurpleFade3 & \colorbox{juPurpleFade3}{\makebox(14,14){~}} & \tt juGreyFade3 & \colorbox{juGreyFade3}{\makebox(14,14){~}} \\
  \end{tabular}
\end{frame}

\begin{frame}{Colors}
  Color tints for the secondary colors.
  \bigskip
  
  \centering
  \begin{tabular}{ >{\raggedleft\arraybackslash} m{3.5cm} m{1cm}  >{\raggedleft\arraybackslash} m{3.5cm} m{1cm} }
    \tt juYellowFade1 & \colorbox{juYellowFade1}{\makebox(14,14){~}} & \tt juTurquoiseFade1 & \colorbox{juTurquoiseFade1}{\makebox(14,14){~}} \\
    \tt juYellowFade2 & \colorbox{juYellowFade2}{\makebox(14,14){~}} & \tt juTurquoiseFade2 & \colorbox{juTurquoiseFade2}{\makebox(14,14){~}} \\
    \tt juYellowFade3 & \colorbox{juYellowFade3}{\makebox(14,14){~}} & \tt juTurquoiseFade3 & \colorbox{juTurquoiseFade3}{\makebox(14,14){~}} \\[2em]
    \tt juDarkBlueFade1 & \colorbox{juDarkBlueFade1}{\makebox(14,14){~}} & & \\
    \tt juDarkBlueFade2 & \colorbox{juDarkBlueFade2}{\makebox(14,14){~}} & & \\
    \tt juDarkBlueFade3 & \colorbox{juDarkBlueFade3}{\makebox(14,14){~}} & & \\
    
  \end{tabular}
\end{frame}

\subsection{Usage}

\begin{frame}[fragile]{Using Colors}

Colors can be used with any commands, for example:
\begin{center}
    \begin{tabular}{ll}
    \toprule
        \mintinline{latex}{\textcolor{juYellow}{Lorem ipsum}} & \textcolor{juYellow}{Lorem ipsum} \\
    \bottomrule
    \end{tabular}
\end{center}

\medskip
Some predefined commands that use these colors:

\begin{center}
    \begin{tabular}{ll}
    \toprule
        \mintinline{latex}{\alert{Lorem ipsum}} & \alert{Lorem ipsum} \\
        \mintinline{latex}{\alertExample{Lorem ipsum}} & \alertExample{Lorem ipsum} \\
        \mintinline{latex}{\highlight{Lorem ipsum}} & \highlight{Lorem ipsum} \\

    \bottomrule
    \end{tabular}
\end{center}

\medskip
The colors are also used in different predefined \hyperlink{environments}{\textcolor{juDarkBlue}{environments}} and \hyperlink{blocks}{\textcolor{juDarkBlue}{blocks}}.

\end{frame}


\section{Fonts}
\label{sec:fonts}

\subsection{Selecting a font theme}

\begin{frame}[fragile,label=selectfonts]{Fonts}

JU's Graphic Manual uses \alert{BentonSans} and \alert{Scala (Sans) OT} as their main fonts, but they are not free and not available on Overleaf.\medskip

  Therefore, this theme provides a number of alternatives:
  
      \begin{itemize}
        \item \alert{\texttt{arial}} uses the recommended web font from JU's Graphic Manual, which is plain old Arial.
        \item \alert{\texttt{franklin}} uses Libre Franklin, which supposedly is the closest free equivalent to BentonSans.  (It doesn't support \textsc{small caps} though.)
        \item \alert{\texttt{source}} uses Adobe's Source fonts, which are slightly more different from BentonSans, but look potentially nicer.
        \item \alert{\texttt{fira}} is the default font of the \textsc{Metropolis} theme, but has no similarity to JU's recommended fonts.
    \end{itemize}
\end{frame}

\begin{frame}[fragile]{Selecting a Font Theme}

Select a font theme with the option \texttt{typeface=<...>}:

\begin{center}
\begin{adjustbox}{max width=\textwidth}
\begin{tabular}{llll}
\toprule
\bf Typeface & \bf Sans font & \bf Mono font & \bf Serif font \\
\midrule
    \texttt{arial} & Arial/Inter & Courier New & Times New Roman \\
%    \multicolumn{4}{l}{~~~\footnotesize\itshape --- Recommended ``web fonts'' from JU's Graphic Manual, but a bit plain.} \\[.4em]
    \texttt{franklin} & Libre Franklin & Hack & Libre Baskerville \\
%    \multicolumn{4}{l}{~~~\footnotesize\itshape --- Closest free equivalent to Benton Sans, but doesn't have \textsc{small caps}.} \\[.4em]
    \texttt{source} & Source Sans Pro & Source Code Pro & Source Serif Pro \\
%    \multicolumn{4}{l}{~~~\footnotesize\itshape --- Adobe open fonts, still close to Benton Sans.} \\[.4em]
    \texttt{fira} & Fira Sans & Fira Code/Mono & Charter \\
%    \multicolumn{4}{l}{~~~\footnotesize\itshape --- Default fonts of the Metropolis theme; no similarity to JU's fonts.} \\[.4em]
\bottomrule
\end{tabular}
\end{adjustbox}
\end{center}

\subsection{Blocks}

{\metroset{block=transparent}

    \end{warningblock}
\end{frame}
}

\subsection{Code}
\begin{frame}[fragile,stretch]{Code Blocks}
    
    Since I frequently need to show code examples, I defined some styles and custom commands that can be included with:
    
    \mint{latex}|\usepackage{myminted}|
    
    This uses the \href{http://tug.ctan.org/macros/latex/contrib/minted/minted.pdf}{{\small\faExternalLink*}~\texttt{minted}} package to typeset code with automatic syntax highlighting.
    \medskip

    \begin{warningblock}{\faExclamationTriangle{}\enspace{}Important}
    Every frame that contains code must have the \texttt{[fragile]} option set, or compilation will break with many cryptic errors!
    \end{warningblock}
\end{frame}

\begin{frame}[fragile]{Code Blocks}
    I also defined some commands to easily produce code blocks like the following; see the \LaTeX{} source for details:\medskip
    
    \begin{beamercodeblock}\vspace{-.6em}
      \begin{minted}[linenos,fontsize=\footnotesize]{java}
      // Your First Program

      class HelloWorld {
        public static void main(String[] args) {
          System.out.println("Hello, World!"); 
        }
      }
      \end{minted}
    \end{beamercodeblock}
    \beamercaptionblock{\textbf{Listing 1:} A hello world program in Java.}

\end{frame}


\subsection{Bibliography}
\begin{frame}[fragile,stretch]{Bibliography}
    
    I use \texttt{biblatex} with some custom definitions, which I also bundled in their own package:
    
    \mint{latex}|\usepackage{mybiblatex}|
    
    Mainly, this will suppress output of URLs and DOIs, and instead turn the paper title into hyperlinks.  Here's an example:

    \begin{itemize}
        \item \fullcite{iki-aizawa-2020-language}
    \end{itemize}
\end{frame}

\appendix
\metroset{sectionpage=none}
\section{Bibliography}

\begin{frame}
