[Tex/LaTex] Add Author Name, Short Title, Date, and Pages to Footline

Question

I'm using the default theme. Not sure, if that theme uses the infolines outer theme or not. All I'm trying to achieve is add my name, the short title, the date (maybe with custom date format) and page number.

I thought there might be some simple way to achieve this with \setbeamertemplate{footline}, but all I could find was [page number] as option. How would I add the other attributes? Do I have to use \makeatother (I don't particularly understand how that works in first place)?

Answer 1

You can define your own footline

\documentclass{beamer}

\makeatletter
\setbeamertemplate{footline}{
    \leavevmode%
    \hbox{%
        \begin{beamercolorbox}[wd=.333333\paperwidth,ht=2.25ex,dp=1ex,center]{author in head/foot}%
            \usebeamerfont{author in head/foot}\insertshortauthor
        \end{beamercolorbox}%
        \begin{beamercolorbox}[wd=.333333\paperwidth,ht=2.25ex,dp=1ex,center]{title in head/foot}%
            \usebeamerfont{title in head/foot}\insertshorttitle
        \end{beamercolorbox}%
        \begin{beamercolorbox}[wd=.333333\paperwidth,ht=2.25ex,dp=1ex,right]{date in head/foot}%
            \usebeamerfont{date in head/foot}\insertshortdate{}\hspace*{2em}
            \insertframenumber{} / \inserttotalframenumber\hspace*{2ex} 
        \end{beamercolorbox}%
    }%
    \vskip0pt%
}
\makeatother

\title{test}
\author{Einstein}

\begin{document}
    
    \begin{frame}
        test
    \end{frame}
    
\end{document}
