% \section{Introduction}\label{sec:introduction}
%
% This \LaTeX{} class aims to implement the guidelines on scientific writing of the art history institute (Kunstgeschichtliches Institut - short: KGI) at Ruhr University Bochum.^^A
% \footnote{Guidelines version July 2023 \url{https://kgi.ruhr-uni-bochum.de/wp-content/uploads/2023/04/Anleitung-zum-Erstellen-von-Hausarbeiten-im-Fach-Kunstgeschichte_Fassung-Juli-2023.pdf}}
%
% Note, that at this point this is not an official class made by anyone at the institute but rather a free-time hobby project of me, Joran, who knows \LaTeX{} from studying Electrical Engineering and just wants to help out some friends studying art history.
%
% You can find the latest releases and the development of this project at GitHub: \url{https://github.com/rub-kgi/rub-kunstgeschichte-latex}
%
% \section{Usage}\label{sec:usage}
%
% To use this class, simply specify it as the document class.^^A
% \footnote{You can also find a complete example usage of this class in \autoref{sec:example}.}
% \begin{sourceverb}
% \documentclass{rub-kunstgeschichte}
% \end{sourceverb}
%
% \subsection{Caveats}
% When using this class, some packages are loaded automatically with options (see also \autoref{sec:implementation:package-loading}).
% That means that you can't reload the same package with different options without risking an option clash error.
% The relevant packages offer other ways to change their options in the preamble:
%
% \DescribePackage{biblatex}
% Customize citations and bibliography.
%
% \verb|\ExecuteBibliographyOptions|\oarg{entrytype}\marg{options} can be used to set most options,
% but some can only be set at the time of loading the \pkg{biblatex} package.
% Those can be set in the class options using the \optn{biblatex} key (see also \autoref{sec:usage:class-options}).
%
% \DescribePackage{hyperref}
% Customize behavior of clickable elements and pdf meta-data.
%
% \verb|\hypersetup|\marg{options} should be used for nearly all options.
% The few options that can only be given at load time of the package have to be passed along using the \optn{hyperref} class option (see also \autoref{sec:usage:class-options}).
%
% \DescribePackage{setspace}
% Overwrite the 1.5 line-spacing setting.
%
% Either \verb|\singlespacing|,
% \verb|\doublespacing|
% or for custom spacing factors also
% \verb|\setstretch|\marg{baselinestretch}.
%
% \DescribePackage{geometry}
% Overwrite geometry options such as the page margin settings.
%
% \verb|\geometry|\marg{options}
%
% \subsection{Class options}\label{sec:usage:class-options}
% You can pass several \meta{options} to the class by using
% \begin{sourceverb}
% \documentclass|oarg(options){rub-kunstgeschichte}
% \end{sourceverb}
% The \meta{options} are key/value pairs that sometimes defer to a default value when only the key is given.
%
% \DescribeOption{biblatex}
% Pass along options to the \pkg{biblatex} package. They overwrite default options set by this class.
%
% \DescribeOption{hyperref}
% Pass along options to the \pkg{biblatex} package. They do \textbf{not} overwrite default options set by this class as they are set after loading the package using the \verb|\hypersetup| command.
% To overwrite them, use \verb|\hypersetup|\marg{options} in the preamble.
%
% \DescribeOption{parskip}
% \DescribeDefault{\optn{true}}
% Specify wether to load the \pkg{parskip} package to remove indentation at the start of paragraphs.
%
% \DescribeOption{noparskip}
% \DescribeDefault{\optn{true}}
% The complementary option to the \optn{parskip} option.
%
% If neither \optn{parksip} nor \optn{noparskip} are given, the \pkg{parskip} package is automatically loaded by default.
%
% \subsection{Macros}\label{sec:usage:macros}
%
% \DescribeMacro{\printbibliographies} \oarg{options}
%
% Prints the bibliography, divided into two subbibliographies.
% One for primary sources and one for secondary literature, as suggested in section 3.7.1 of the guidelines on page 14.
% It uses the keyword mechanism to distinguish primary sources i.e. in order for a bib entry to be sorted into the primary sources section, it needs the \texttt{source} keyword.
% E.g. the bible would be considered a primary source:
% \begin{sourceverb}
% @inbook{bible,
%     author    = {{The Bible}},
%     title     = {The Holy Bible: King James Version},
%     |ldots
%     keywords  = {source}
% }
% \end{sourceverb}
% All other entries which don't have the \texttt{source} keyword will be sorted into the secondary literature section of the bibliography.
%
% You can customize the behavior of the macro using key-value \meta{options}. The option keys that are currently available are \optn{heading}, \optn{heading-primary} and \optn{heading-secondary} to overwrite the headings of the bibliography and the two subbibliographies respectively.
%
% \DescribeMacro{\maketitle} \oarg{titlepage-info}
%
% The native command \cs{maketitle} is redefined to create the title page according to the template in the guidelines.
% The new title page needs more information than the standard one.
% Besides the name of the author and title it needs more details about the author such as the matriculation number as well as information about the seminar the work is associated with.
% The extra info can be passed as key-value pairs to the optional \meta{titlepage-info} argument of the redefined \cs{maketitle} macro
% \DescribeMacro{\configureTitlepage}
% or to the \cs{configureTitlepage} macro implemented for just this task.
% The following custom keys are implemented:
% \begin{description}
% \ItemDescribeOption[titlepage]{email} The email of the author.
% \ItemDescribeOption[titlepage]{matricnum} The matriculation number of the author.
% \ItemDescribeOption[titlepage]{author-semester} The number of semesters the author has studied the subject.
% \ItemDescribeOption[titlepage]{seminar-semester} The semester in which the seminar takes place in. E.g. \optn{Sommersemester 2024} or \optn{Wintersemester 2023/24}.
% \ItemDescribeOption[titlepage]{seminar-lecturer} The name of the lecturer of the seminar.
% \ItemDescribeOption[titlepage]{seminar-name} The name of the seminar itself.
% \ItemDescribeOption[titlepage]{seminar-degree} The degree in which the author has taken the seminar in.
% \ItemDescribeOption[titlepage]{seminar-module} The module in which the author has taken the seminar in.
% \ItemDescribeOption[titlepage]{seminar-cp} The credit points the author will be rewarded with when completing the seminar.
% \end{description}
% Additionally you should set the normal \cs{author}, \cs{date} and \cs{title} info in the preamble.
%
% Note, that in contrast to e.g. the headers of the bibliography, the title page is not translated into the document language.
% The guidleines specify that exactly this template should be used and to our understanding this means that it should always be written in german, regardless of the document language.
%
% \DescribeMacro{\appendix}
%
% To indicate the end of the main content and start of the appendix, the \cs{appendix} command is used in \LaTeX. Here, the command was redefined to automatically disable section numbering for the appendix as suggested in the guidelines. This means you can just use normal section commands such as
% \begin{sourceverb}
% \section{Figures}
% \end{sourceverb}
% after calling
% \begin{sourceverb}
% \appendix
% \end{sourceverb}
% and it will not have a section number.
%
% \subsection{Translations}\label{sec:usage:translations}
%
% The class uses the \pkg{translations} package to allow multi-lingual strings. The default language is english. To tell it which language it should use, you can load a package like \pkg{babel} with the corresponding language as the package option in the preamble. E.g. for german using the new spelling rules
% \begin{sourceverb}
% \usepackage[ngerman]{babel}
% \end{sourceverb}
%
% All pre-defined strings this class prints on the page of the document (such as the headings of the bibliographies when using \cs{printbibliographies}) are available in multiple languages.
% So far this package only defines its strings for english and german, but you can define them for other languages too.\footnote{E.g. using the \cs{declaretranslation} command. For more info, refer to the documentation of the \pkg{translations} package: \url{https://ctan.org/pkg/translations}}
%
% The translation string definitions can be found in \autoref{sec:implementation:translations}.

% \begin{option}{biblatex}
% The \optn{biblatex} option stores its content in a macro until it is later passed along to the \pkg{biblatex} package after specifying the default options (see \autoref{sec:implementation:package-loading:bibliography}).

% \begin{option}{hyperref}
% The \optn{hyperref} option passes its content along immediately, to be used as options when the \pkg{hyperref} package is loaded.

% Prints the bibliography using the native \cs{printbibliography} macro, but divides it into sections for primary sources and secondary literature. The keyword \texttt{source} is used to sort entries into the primary sources section.

%    \begin{macrocode}
\newcommand{\printbibliographies}[1][]{%

    \section{Introduction}
    The \textsf{rub-kunstgeschichte} class aims to implement
    the guidelines on scientific writing of the art history institute
    ``KGI'' (\textit{Kunstgeschichtliches Institut})
    at Ruhr University Bochum.

    This example document showcases a typical use
    of the \textsf{rub-kunstgeschichte} class.
    Just by using the class, the page is already formatted
    so that the typeset text has 12pt font size,
    there is a 1.5 times line-spacing present
    and the page size is A4 with 2cm margins at top, left and bottom,
    as well as a 4cm margin on the right.\autocite[See:][11]{guidelines}

    Also, paragraphs don't have an indentation
    in the first line by default,
    contrary to typical \LaTeX{} documents.
    Furthermore the \texttt{hyperref} package
    is automatically loaded to enable clickable
    links and references.

    Notably, the first page is a custom title page
    that aims to recreate the titlepage template
    of the guidelines in \LaTeX.
    Note, how the fields have descriptive default values in CAPS,
    so that you can easily see which information is still missing
    for the title page.
    As the documentation of this class states,
    you can either pass the corresponding key-value options
    into an optional argument of \verb|\maketitle|,
    or use the \verb|\configureTitlepage| macro
    in the preamble.\footnote{For a full list of titlepage options
    refer to the \texttt{rub-kunstgeschichte} class documentation.}

    We use the \texttt{babel} package
    to set the language to german
    (even though this example document is actually written in english)
    to showcase how headings are automatically translated.

    \section{How to cite sources}
    This class automatically loads the \texttt{biblatex} package
    for sophisticated bibliography and citations.
    The class also sets some options by default
    that make \texttt{biblatex} behave closer to the
    suggested citation style in the guidelines of the institute.

    You can cite sources using the \verb|\autocite| command,
    which is configured by this class to use footnotes
    \autocite{exampleArticle}.
    Page numbers can be added in the optional argument
    \autocite[394]{exampleBook}
    and citation signals in a second one
    that comes before the one for page numbers
    \autocite[see][]{exampleWebsite}.
    You can even cite multiple sources at once
    using the \verb|\autocites| command
    \autocites[111]{exampleBook}[see also][13]{exampleArticle}.

    For more information refer to the documentation
    of the \texttt{biblatex} package
    \autocite{biblatexDocs}
    or the biblatex cheatsheet
    \autocite{biblatexCheatsheet}.

    \appendix

    \section{The appendix}

    We finished the main content of the example document
    so we call \verb|\appendix| before this first appendix section.
    It will automatically disable section numbering
    for any appendix sections.

    Here, we can include a bibliography
    containing all cited sources,
    divided into primary and secondary literature,
    with \verb|\printbibliographies|.
    Primary literature (also called a \textit{source})
    is something like the bible\autocite{bible},
    letters, treatises etc.
    We put the bibliography on a new page
    by using \verb|\clearpage| before printing it.
    Note, that since we used
    \verb|\usepackage[ngerman]{babel}| in the preamble,
    the headings of the bibliography are typed in german.

    \clearpage
    \printbibliographies

    \clearpage
    \section{Figures}

    The guidelines suggest putting all figures
    in a dedicated appendix section
    after the bibliography instead of in between the
    main content text.\autocite[10,25]{guidelines}

    We can include figures with \verb|\includegraphics|
    inside a \texttt{figure} environment.
    We also add a caption with the meta information
    of the shown artwork,\autocite[25--26]{guidelines}
    as well as a short caption in square brackets
    and a label for back-referencing.

    \begin{figure}[H]
        \centering
        \includegraphics[width=0.8\linewidth]{example-image-golden}
        \caption{An Artist, The artwork title, Where was it made?,
        The year, Material, Measurements, Where is it kept?,
        Inventory number.}
        \label{fig:exampleArtwork}
    \end{figure}
