 # hackthefootline
-Version 2017/08/04
+## Arbitrary footline selection for LaTeX beamer's standard themes.
 
-Provides arbitrary footline selection for LaTeX beamer's standard themes.
+Some `beamer` themes provide footlines -- and some do not.  
+Now, if one wants to have a footline, he is restricted to the (outer) themes providing them or loads multiple themes. On top of that, these provided footlines are only configurable by redefining them as a whole, which is quite uncomfortable and yields many lines of additional code.
 
+`hackthefootline` is a package taking over, defining and redefining different footlines, so they can be configured using key-value syntax. Also, it is possible (but *not* recommended) to switch between different footline types during a presentation.
+
+
+
+### Dependencies
+`hackthefootline` depends on the `pgfkeys` package and -- obviously -- on the `beamer` class.  
+
+Additional sophisticated features included also require `appendixnumberbeamer`, `etoolbox`, `calc` and `numprint`, but these four dependencies can be resolved by passing some options to the `hackthefootline` package.

+	%
+	\DescribeMacro{beamer}
+	Since "hackthefootline" is designed to modify "beamer"'s footlines, it is incompatible to any other document class. Therefore, load this package only in "beamer" documents!
+	
+	\medskip
+	\DescribeMacro{pgfkeys}
+	"hackthefootline" heavily depends on the "pgfkeys" package for handling the whole key-value stuff.
+	
+	\bigskip
+	Also, additional sophisticated features require the following packages:
+	
+	\medskip
+	\DescribeMacro{appendixnumber-}\DescribeMacro{beamer}
+	The "appendixnumberbeamer" package implements a simple solution for appendix frames not being calculated into the total number of frames
+	
+	\medskip
+	\DescribeMacro{etoolbox}
+	Provides access on \hologo{eTeX} primitives
+	
+	\medskip
+	\DescribeMacro{calc}
+	Required for basic calculations
+
+	\medskip
+	\DescribeMacro{numprint}
+	Prints out numbers, counters and lengths
+	
+	\bigskip
+	However, the four latter dependencies can be removed by using some package options. See section \ref{behavioropts} for further details.

+	\addcontentsline{toc}{subsection}{Notice: Behavior inside the presentation's appendix}
+	By default, this package \emph{does not count appendix frames} into the total number of frames and resets the counter for frame numbers to 1 as soon as the "\appendix" command is used. Also, frame numbers won't be displayed on footlines inside the appendix.
+	
+	\medskip
+	This behavior can be suppressed by passing the \texttt{countappendixframes} option.

+
+	\section{Using the package}
+	The "\usepackage[<Options>]{hackthefootline}" command loads the package\footnote{To do so, the package has to be installed in a location where \LaTeX\ is able to find it}. A list of all available options can be found in section \ref{packageoptions}.
+	
+	\medskip
+	\textbf{Important note:} You \emph{have} to pass the \emph{footline's number of columns} as an option to the package (available: "onecol", "twocols" or "threecols"). If you don't do so, the footline gets removed completely. \\
+	See section \ref{examples-setup} for some examples.
+	
+	
+	
+	\section{Package options} \label{packageoptions}
+	\subsection{Options influencing the footline's configuration}
+	These options determine the number of columns being used for the footline. \\
+	You \emph{have} to pass one of these options when loading "hackthefootline"; otherwise the footline will be removed completely.
+	
+	\medskip
+	\DescribeMacro{onecol}
+	The \enquote{initial footline hack} produces a one--column footline
+	
+	\medskip
+	\DescribeMacro{twocols}
+	The \enquote{initial footline hack} produces a two--column footline
+	
+	\medskip
+	\DescribeMacro{threecols}
+	The \enquote{initial footline hack} produces a three--column footline
+	
+	\subsection{Options influencing the package's behavior} \label{behavioropts}
+	These options can be passed to disable additional features and remove dependencies on other packages.
+	
+	\medskip
+	\DescribeMacro{countappendix-}\DescribeMacro{frames}
+	If the "countappendixframes" option is passed to the package, appendix frames are counted into the total number of frames. \\
+	\textit{Removes the following dependencies:} "appendixnumberbeamer", "etoolbox"
+	
+	\medskip
+	\DescribeMacro{nofun}
+	Doesn't support frame numbers being shown as \enquote{percent of presentation} \\
+	\textit{Removes the following dependencies:} "calc", "numprint"
+
+
+
+	\section{Configuring the footline}
+	The internal mechanisms of "hackthefootline" are using templates for displaying the provided information.
+	Each template is available in different styles, which can be switched using the provided key value syntax:
+	
+	\medskip
+	\DescribeMacro{\htfconfig}
+	Use "\htfconfig{key1=value1, key2=value2, …}" to modify the current configuration of the footline. Changes apply instantly. \\
+	See section \ref{examples-switchtemplates} for examples.
+	
+	\bigskip
+	All available keys and values are listed below being depicted as follows:
+	
+	\medskip
+	\DescribeOption{key}{possible values}{Description of the values' effects}
+	
+	\medskip
+	\textbf{Annotations:}
+	\begin{itemize}
+		\item
+			The default values of the keys depend on the number of columns chosen when loading the package. See section \ref{defaultconfig} for further details.
+		\item
+			\textit{Templates not visible} in the default configuration have been hidden by setting the value of the according key to "none". Apply another value to this key and the template will show up. \\
+			\textit{Templates visible} in the default configuration can be hidden by setting the value of the according key to "none" (there's only one exception: "atsep"). \\
+			See section \ref{examples-switchtemplates} for examples.
+	\end{itemize}
+	
+	\bigskip
+	\DescribeOption{cols}{one, two, three, none}{%
+		The number of colums used for the footline:
+		\begin{description}\itemsep0pt
+			\item[one]
+				Use a footline consisting of a single column
+			\item[two]
+				Use a footline consisting of two columns
+			\item[three]
+				Use a footline consisting of three columns
+			\item[none]
+				Remove the footline completely
+		\end{description}
+		This key is provided although it is \emph{not} recommended to change its value within a document.
+		When initializing "hackthefootline" using a column option and switching to the "none" style, there will be a whitespace \enquote{reserved} for the footline left. \\
+		The other way round, when initializing "hackthefootline" without a column option and switching to a footline, the footline will be cut off at half of its height.
+	}
+	
+	\DescribeOption{title}{short, long, none}{%
+		Sets the title type displayed in the footline:
+		\begin{description}\itemsep0pt
+			\item[short]
+				Show the short title given in the square braces of the \texttt{\textbackslash title} command. \\
+				When no short title is given, the long title will be used.
+			\item[long]
+				Show the long title given in the curly braces of the \texttt{\textbackslash title} command.
+			\item[none]
+				Don't show any title inside the footline
+		\end{description}}
+	
+	\DescribeOption{authinst}{onlyauthor, onlyinst, instpths, authpths, both, none}{%
+		Influences the way author and institute are displayed:
+		\begin{description}\itemsep0pt
+			\item[onlyauthor]
+				Show only the author's name
+			\item[onlyinst]
+				Show only the institute's name
+			\item[instpths]
+				Show both, author and institute, but put the institute into parentheses
+			\item[authpths]
+				Show both, author and institute, but put the author into parentheses
+			\item[both]
+				Show both and separate them using a comma
+			\item[none]
+				Show neither author, nor institute
+		\end{description}
+		All templates use the values specified for short author / short institute.
+	}
+	
+	\DescribeOption{date}{short, long, none}{%
+		The date displayed in the footline:
+		\begin{description}\itemsep0pt
+			\item[short]
+				Show the short date
+			\item[long]
+				Show the long date
+			\item[none]
+				Do not show any date
+		\end{description}}
+	
+	\DescribeOption{framenrs}{counter, fraction, percent, none}{%
+		Controls the type of frame number shown in the footline:
+		\begin{description}\itemsep0pt
+			\item[counter]
+				Only show the number of the current frame
+			\item[fraction]
+				Show the number of the current frame as well as the total number of frames
+			\item[percent]
+				Display the current progress of the presentation displayed as a percent value \\
+				When setting this value, make sure that you didn't pass the "nofun" option when loading the package, otherwise an error message will be thrown.
+			\item[none]
+				Do not show frame numbers
+		\end{description}}
+	
+	\DescribeOption{atsep}{colon, comma, space}{%
+		Sets the character used to separate author and title when using the "onecol" footline:
+		\begin{description}\itemsep0pt
+			\item[colon]
+				Use a colon as separator
+			\item[comma]
+				Use a comma as separator
+			\item[space]
+				Use a space as separator
+		\end{description}}
+	
+	
+	
+	\section{Default configurations} \label{defaultconfig}% TODO: Real pictures
+	Depending on the selected number of columns, the default configuration of the footlines is as follows:
+	
+	\subsection*{One--column footline}
+	"\htfconfig{%" \\
+	"    title=short, authinst=both," \\
+	"    date=none, framenrs=fraction, atsep=colon}" \\[\smallskipamount]

+	"    A short introduction on \texttt{hackthefootline}'s facilities}" \\
+	"\author[S. Friedl]{Sebastian Friedl}" \\
+	"\institute[Some Institute]{Some Institute far, far away}" \\
+	"\date[2018/01/15]{January 15, 2018}"
+	
+	\medskip
+	We will start with step 1 and continue further on, each step is changing the result of the last one.
+

-	\emph{Load the \texttt{hackthefootline} package only in \LaTeX\ beamer documents!} \\
-	The package itself depends on the following other packages:
-	
-	\medskip
-	\DescribeMacro{appendixnumber-}\DescribeMacro{beamer}
-	The \texttt{appendixnumberbeamer} package implements a simple solution for appendix frames not being calculated into the total number of frames
-	
-	\medskip
-	\DescribeMacro{etoolbox}
-	Provides access on \hologo{eTeX} primitives
-	
-	\medskip
-	\DescribeMacro{calc}
-	Required for basic calculations
-
-	\medskip
-	\DescribeMacro{numprint}
-	Prints out numbers, counters and lengths
-	
-	\bigskip
-	The dependencies can be removed completely by passing some options to the package. See section \ref{packageoptions} for further details.

-	\subsection*{Notice: Behaviour inside the presentation's appendix}
-	\addcontentsline{toc}{subsection}{Notice: Behaviour inside the presentation's appendix}
-	By default, this package \emph{does not count appendix frames} into the total number of frames and resets the counter for frame numbers to 1 as soon as the \ltxcmd{\appendix} command is used. \\
-	Also, frame numbers won't be displayed on frames inside the appendix.
-	
-	\medskip
-	This behaviour can be avoided by passing the \texttt{countappendixframes} option to the package.

-	
-	\section{Using the package}
-	The \mintinline{LaTeX}{\usepackage[<Options>]{hackthefootline}} command loads the package\footnote{To do so, the package has to be installed in a way \LaTeX\ is able to find it}. The complete list of options can be found in section \ref{packageoptions}.
-	
-	\medskip
-	At least, you have to pass the \emph{footline's number of columns} as an option to the package \textit{(available: \texttt{onecol}, \texttt{twocols} or \texttt{threecols})}. If you don't do so, the footline gets removed.
-	
-	
-	\section{Package options} \label{packageoptions}
-	The \texttt{hackthefootline} package provides the following options:
-	
-	\medskip
-	\DescribeMacro{onecol}
-	The \enquote{initial footline hack} produces a one--column footline
-	
-	\medskip
-	\DescribeMacro{twocols}
-	The \enquote{initial footline hack} produces a two--column footline
-	
-	\medskip
-	\DescribeMacro{threecols}
-	The \enquote{initial footline hack} produces a three--column footline
-	
-	\medskip
-	\DescribeMacro{countappendix-}\DescribeMacro{frames}
-	If the \texttt{countappendixframes} option is passed to the package, appendix frames are counted into the total number of frames. \\
-	\textit{Removes following dependencies: \texttt{appendixnumberbeamer}, \texttt{etoolbox}}
-	
-	\medskip
-	\DescribeMacro{nofun}
-	Doesn't support frame numbers being shown as \enquote{percent of presentation} \\
-	\textit{Removes following dependencies: \texttt{calc}, \texttt{numprint}}
-	
-	
-	\section{Default configurations}	
-	\subsection*{One--column footline}
-	\begin{tikzpicture}
-		\draw (-.5\textwidth,1.25ex) rectangle (.5\textwidth,-1.25ex);
-		\node[right] at (-.5\textwidth,0) {Short author, short institute:~~~~Short title};

-	
-	
-	\section{Defined templates}
-	The \texttt{hackthefootline} package defines templates with a variety of styles to provide easy personalisation. All defined templates are listed in table \ref{deftemplates}. Switching between different styles of a template is described in section \ref{switchingtemplates}.

-		
-		\caption{Defined templates and styles}
-		\label{deftemplates}
-	\end{table}
-	
-	\section{Switching styles} \label{switchingtemplates}
-	The styles of the templates at the initial hack are selected depending on the footline's default settings. \\
-	You are able to switch styles inside the \texttt{document} environment by \dots
-	\begin{enumerate}
-		\item changing the current settings using the commands listed in table~\ref{deftemplates} \textit{\textbf{and}}
-		%
-		\item applying the settings with the \ltxcmd{\hackthefootline} command. \par
-			  \textbf{Your changes to the footline's settings only apply when executing this command.}
-	\end{enumerate}
-	
-	\textit{Example:} \vspace{-.75em}
-	\begin{minted}[gobble=2,tabsize=4]{LaTeX}
-		\htflongdate		% Changes current settings ...
-		\htfauthinst
-		\hackthefootline	% ... and applies the changes
-	\end{minted}
-	
-	\bigskip
-	If a template is not shown in the current configuration (e.~g. the frame number in the two--column footline), just switch the style:
-
-	\medskip
-	\begin{tikzpicture}
-		\draw (-.5\textwidth,1.25ex) rectangle (0,-1.25ex);
-		\draw ( .5\textwidth,1.25ex) rectangle (0,-1.25ex);
-		\node[left]  at (0,0) {Short author};
-		\node[right] at (0,0) {Short title};
-	\end{tikzpicture}
-	\vspace{-1.5em}
-	\begin{minted}[gobble=2,tabsize=4]{LaTeX}
-		\htfcounterframenrs
-		\hackthefootline
-	\end{minted}
-	\begin{tikzpicture}
-		\draw (-.5\textwidth,1.25ex) rectangle (0,-1.25ex);
-		\draw ( .5\textwidth,1.25ex) rectangle (0,-1.25ex);
-		\node[left]  at (0,            0) {Short author};
-		\node[right] at (0,            0) {Short title};
-		\node[left]  at ( .5\textwidth,0) {1};
-	\end{tikzpicture}
-	
-	
-	\bigskip\bigskip
-	Also, a template shown in the current configuration can be \enquote{removed} by switching the style:
-	
-	\medskip
-	\begin{tikzpicture}
-		\draw (-.5\textwidth,1.25ex) rectangle (0,-1.25ex);
-		\draw ( .5\textwidth,1.25ex) rectangle (0,-1.25ex);
-		\node[left]  at (0,            0) {Short author};
-		\node[right] at (0,            0) {Short title};
-		\node[left]  at ( .5\textwidth,0) {1};
-	\end{tikzpicture}
-	\vspace{-1.5em}
-	\begin{minted}[gobble=2,tabsize=4]{LaTeX}
-		\htfnoauthinst
-		\hackthefootline
-	\end{minted}
-	\begin{tikzpicture}
-		\draw (-.5\textwidth,1.25ex) rectangle (0,-1.25ex);
-		\draw ( .5\textwidth,1.25ex) rectangle (0,-1.25ex);
