%\vspace{2\baselineskip}
%\begin{abstract}
%  The following documents a set of \LaTeX{} classes created for the Hochschule Hannover.
%  They are intended to ease the workflow when writing documents by providing a common
%  formating basis that should work for pretty much everything a studend will be expected
%  to write. This can be simple one-paged documents, excercises, lab-reports, papers or
%  bachelors and masters thesises.
%
%  The classes provide interfaces to modify commend requriements, provide commands to get
%  specifics like the logo and provide and pre-configure comonly needed packages. This
%  should get you going imidealty and reduce the setuptime significantly.

%\section{The different classes}
%
% The project classes provided by the Project all carry the |HsH-| prefix. Here is a
% list of the available classes and some expleantion on when to use which class.
% \begin{description}
%   \item\DescribeClass{HsH-article}
%         A article-class based on \KOMAScript{}s \cls{scrartcl}.
%         It is designed for quick and compact documents and is useful for writing
%         lab-protocols and alike. It does not have chapters and therefore never
%         breaks to a new page on its own.
%   \item\DescribeClass{HsH-report}
%         A report-class based on \KOMAScript{}s \cls{scrreprt}.
%         This is probably the most useful class, as it can be used for a wide
%         variety of documents (beginning with lab-reports and ending at complete
%         thesis). The line between article and report is somewhat blurry, so use
%         as you see fit.
%   \item\DescribeClass{HsH-standalone}
%         A helper class based based on the \cls{standalone}
%         class. It is designed only for creating images as separate documents to
%         keep things organized and compiler times low. It is useful for creating
%         graphs, circuit diagrams or other kind of complex sub documents.
% \end{description}
%
%\section{Document options}
% To configure the behavior and style of documents using this class, options can be
% passed via the |\documentclass|\oarg{options}\marg{document-class} command.
%
% It should be noted that all unknown keys will pe passed to the parrent class and a
% log-message issued.
%
% \subsection{Generic options share by all classes}
%   These Options are avalable regardless of documentclass and modify common things.
%
%   \DescribeOption{fontfamily} \DescribeOption{sans}\DescribeOption{roman}
%   The \opt{fontfamily=\meta{opt}} option configures which font-style is used.
%   For convenience there are also short-forms providet.
%   The avalable options are:
%   \begin{options}
%     \item[sans\OR sans-serif] A sans-serif font is used (similar to Arial)
%     \item[roman\OR serif] A serif font is udes (similar to Times-new-Roman)
%   \end{options}
%
%   \DescribeOption{language} \DescribeOption{english}\DescribeOption{german}
%   The \opt{language=\meta{opt}} option set the main language you write in. It ensures
%   texts like auto-generated headings are localised properly.
%   You can pass in any language-name understood by the \pkg{babel} package. German is
%   the default.
%   For convenience there are also short-forms providet.
%   \medskip
%
%   \DescribeOption{faculty} \DescribeOption{f1}\DescribeOption{f2}\DescribeOption{f3}\DescribeOption{f4}\DescribeOption{f5}
%   The \opt{faculty=\meta{opt}} option configures which faculties logo is used.
%   For convenience there are also short-forms providet.
%   The avalable options are:
%   \begin{options}
%     \item[none\OR false] A gray, non-faculty specific logo is used.
%     \item[1\OR f1] The blue logo of faculty 1 is uded.
%     \item[2\OR f2] The green logo of faculty 2 is uded.
%     \item[3\OR f3] The orange logo of faculty 3 is uded.
%     \item[4\OR f4] The red logo of faculty 4 is uded.
%     \item[5\OR f5] The purple logo of faculty 5 is uded.
%   \end{options}
%
% \subsection{Options for modifying the document}
%   The following options are only avalable for documents (so not utility classes).
%
%   \DescribeOption{linespacing}
%   \DescribeOption{singlespacing}\DescribeOption{onehalfspacing}\DescribeOption{doublespacing}
%   The \opt{linespacing=\meta{opt}} option configures the spacing in beween lines.
%   For convenience there are also short-forms providet.
%   The avalable options are:
%   \begin{options}
%     \item[single] No additional space is added in between lines.
%     \item[onehalf] Aproximalty half a line of empty space is added inbetween lines.
%     \item[double] About a full linehight is left in between lines.
%   \end{options}
%
%   \DescribeOption{parskip}
%   The \opt{parskip=\meta{opt}} option configures the spacing in beween paragraphs.
%   This is an extending option originally implemented by \KOMAScript{}.
%   \begin{options}
%     \item[never] No inter-paragraph spacing will be inserted even if additional
%           vertical spacing is needed for vertical adjustment with |\flushbottom|.
%     \item[never+] No inter-paragraph spacing will be inserted. There must be at least a
%           third of a line of free space at the end of a paragraph.
%     \item[never*] No inter-paragraph spacing will be inserted. There must be at least a
%           quarter of a line of free space at the end of a paragraph.
%     \item[\dots] see \href{http://mirrors.ctan.org/macros/latex/contrib/koma-script/doc/scrguide-en.pdf#table.3.7}{\KOMAScript{} manual, Table 3.7} for more options.
%   \end{options}
%
%   \DescribeOption{headheight}
%   The \opt{headheight=\meta{dim}} option allows you to set the required size of the
%   header. You may need to modify this if you get a |\headheight|\emph{ to low} error
%   message. The emssage should tell you what value you need, but you can pass any
%   valid length.
%
%   \DescribeOption{abstract}
%   The \opt{abstract=\meta{opt}} option allows you to configure different behaviors of the abstract.
%   The availabel options are described below:
%   \begin{options}
%     \item[keywords] Print the \cmd{\keywords} after the abstract.
%     \item[nokeywords] Do \emph{not} print the \cmd{\keywords} after the abstract.
%     \item[totoc] The abstract will be listed in the table of contentes.
%     \item[notoc] The abstract will \emph{not} be listed in the table of contentes.
%   \end{options}
%
%   \DescribeOption{toc}
%   The \opt{toc=\meta{opt}} option configures what is listed in the table of contents.
%   \begin{options}
%     \item[totoc] The table of contentes will list itself.
%     \item[notoc] The table of contentes will \emph{not} list itself.
%     \item[abstract] The abstract will be listed in the table of contentes.
%     \item[noabstract] The abstract will \emph{not} be listed in the table of contentes.
%     \item[\dots] see \href{http://mirrors.ctan.org/macros/latex/contrib/koma-script/doc/scrguide-en.pdf#table.3.5}{\KOMAScript{} manual, Table 3.5} for more options
%   \end{options}
%
%   \DescribeOption{todos}
%   The \opt{todos} option is a simple switch that activates support for the
%   \pkg{todonotes} package. It enables/\-disables the package as well as increasing
%   the pagewidth to make space for the notes.
%
%   You can use the commands from the package to make notes and other anotations
%   (similar to how MS-Words comments work). When you pass \opt{off\OR false} all the
%   anotation will disaper from the PDF while still beeing in the source.
%   \begin{note}
%     setting \opt{todos=off} after having used the option will mostlikly produce
%     compilation errors. These will go away after you remove the temporary files.
%   \end{note}
%
%   \paragraph{Often relevant \KOMAScript\ options}
%   The following options are implemented by the parrent classes and only listed here
%   for completness. For more detils, see \href{http://mirrors.ctan.org/macros/latex/contrib/koma-script/doc/scrguide-en.pdf?page=239#chapter.3}{its manual}.
%   \smallskip
%
%   \DescribeOption{fontsize}
%   The \opt{fontsize=\meta{size}} options takes a size in \opt{pt}. It is usually in therange of
%   10-12, but other sizes can work as well.
%
%   \DescribeOption{paper}
%   The \opt{paper=\meta{size}} options accepts a number of options, most ISO formats
%   are supported, but also others like \opt{letter} or \opt{legal}.
%
%   \DescribeOption{twoside}
%   The \opt{twoside} option sets your document up for doublesided printing. The header
%   and footer will take this into account and binding-correction will be applide along
%   the inner edge.
%
%   \DescribeOption{BCOR}
%   The \opt{BCOR=\meta{dim}} option allows you to define a custom binding-correction.
%   Any valid length can be put here, but to large of a value will shrink the outer
%   margin to a not-desirable level.
%
% \subsection{Standalone specific options}
%   The \cls{standalone} utillity class has some special options which are documented
%   here.
%   \smallskip
%
%   \DescribeOption{margin}
%   The \opt{margin=}\meta{dim} option controlls how much whicspace is added arround
%   you standalone document. This usually looks better which is why the default is
%   0.25\,cm, but you can supress it by passing 0\,cm.
%
%   \DescribeOption{multi}
%   The \opt{multi=}\meta{opt} option defines which enviroment make up a page. It can
%   be passe more than once.
%
%
%\section{Provided commands}
% The clases define a set of commands which are explained in the following section.
%
% \DescribeMacro{\HsHClassName}
% Each class defines the macro |\HsHClassName| to contain its classname. This is
% mostly usefull so internals can reuse the classname, but you could also check
% against it if you needed to.
%
% \subsection{Title matters}
%   \LaTeX{} has a set of default commands which are used to define data for the
%   titlepage, like |\title| or |\author|. The classes define a few additional
%   commands, which are documented her.
%   \smallskip
%
%   \DescribeMacro{\matrikelnr}
%   The |\matrikelnr|\marg{nr[, ..]} macro sets the matrikelnumber of the author(s).
%   It can be a single number or a comma seperated list of numbers. The numbers will
%   be matched to the authors passed into |\author|.
%
%   \DescribeMacro{\professor}
%   You can pass any text to |\professor|\marg{text}, it will be printed on the
%   bottom of the titelpage.
%
%   \DescribeMacro{\keywords}
%   This macro can be used to define keywords which are relevant to your document.
%   They will be printed as part of the abstract and be put into the PDF's meta-data.
%
%   \paragraph{Modifying the Logo}
%   \DescribeMacro{\HsHlogoPath}
%   The logo is loaded from a file whos name is read from \cmd{\HsHlogoPath}. Change
%   it to use a different logo-file.
%
%   \DescribeMacro{\HsHlogoPage}
%   As the PDF file can hae multiple pages, the \cmd{\HsHlogoPage} command stores
%   which page to load.
%
%   \DescribeMacro{\includeHsHlogohere}
%   The macro \cmd{\includeHsHlogohere\oarg{width}} is used by |\maketitle| to produce
%   the logo. But if you want it elsewhere, you can call this macro yourself.
%
%
% \subsection{Commands for document writing}
%   The following commands will be usefull to you when writing a document.
%   \smallskip
%
%   \DescribeMacro{\declarationofauthorship}
%   The command |\declarationofauthorship|\oarg{align} can be used to print a
%   "declatation of authorship" in the current location, similar to how
%   |tableofcontens| and  friends work.
%
%   It will produce a horizontal line, a text block containing the regulatory text and
%   a signature block for every author. The command is localised for both english and
%   german. Using the optional argument, you can define the positioning. Pass \opt{t}
%   for alignment at the top of the page and \opt{b} for bottom alignment
%   (\emph{default}).
%
%   \smallskip
%   The three commands \cmd{\frontmatter},\cmd{\mainmatter} and \cmd{\backmatter} are
%   provided for \cls{report} classes. They seperate document section and
%   automatically set up pagenumer styles. \par
%   \DescribeMacro{\frontmatter}
%   \cmd{\frontmatter} set the pagenumers to capital roman numerals. This is usually
%   required for everything before the first chapter. \par
%   \DescribeMacro{\mainmatter}
%   \cmd{\mainmatter} sets the pagenumbering to "normal" arabic numbers. This is
%   usually the style for the document content. \par
%   \DescribeMacro{\backmatter}
%   \cmd{\backmatter} can be used for apendixes and alike. It sets the pagenumbering
%   to small roman numerals.
%
%
% \subsection{Default \LaTeX{} Commands that are modified}
%   Additionaly, some of \LaTeX{}s default commands are moddified to better fit this
%   class. This is documented here.
%
%   \DescribeMacro{\title}
%   The \cmd{\title\oarg{short-title}\marg{title}} command now takes an additional,
%   optional argument. You can use it for a shorter version of your title, that will
%   be used in the header to save on space.
%
%   \DescribeMacro{\maketitle}
%   The |\maketilte| command if \LaTeX{} default way to create a titlepage. We
%   redefine it to produce a titlepage that matches the sytel typically used on the
%   Hochschle Hannover. This incudes the logo beeing printed, depending on the
%   \opt{f1} to \opt{f5} documentoptions. \par
%   The command now also takes an options alignment-parameter:
%   |\maketitle|\oarg{align}. You can pass \opt{l\OR c\OR r} to get \emph{left},
%   \emph{center} or \emph{right} alignment.
%
% \subsection{Micalanious commands}
%   The following commands are mostly for internal use, but are parte of the interface
%   and might be usefull in some cases.
%   \medskip
%
%   \DescribeMacro{\ifsingleauthor}
%   This allows you to check if |\author| holds one or multiple entries. Using this
%   allows the user to display differernt things for these cases, for example switch
%   words to pural, like this:
%   |\ifsingleauthor{one}{multiple} person\ifsingleauthor{}{s}|
%
%\section{Package loading}
% The classes load some packges for internal use as well as loading and configuring
% common use packages. The details are documented in the following section.
%
% \subsection{Allways loaded packages}
%   \begin{packages}
%     \item[fontenc] for output encoding, set to the european characterset
%     \item[babel] for langauge-specific typesetting
%     \item[bookmark] creates bookmoarks in the PDF
%     \item[hyperref] for easy referencing and linking
%     \item[caption] to customize captions and make references point to the beginning
%     of the floats
%     \item[graphicx] for importing and manipultating images
%     \item[amsmath,amssymb,amsfonts] more options when typesetting math
%     \item[lmodern] sets up the Latin-Modern font
%     \item[setspace] used for configuring linespacing
%     \item[enumitem] more powerfull item-lists and enumerations
%   \end{packages}
%
%   There are also some packages for internal functionalaty that shouln't conserne the
%   user, but they are listed here for completness.
%   \begin{packages}
%     \item[scrbase]
%     \item[pgffor]
%   \end{packages}
%
% \subsection{Conditionally loaded Packages}
%   A subset of packages is only loaded (or loaded with specifig options) depending
%   on options passed to the package
%   \begin{packages}
%     \item[babel] gets configured depending on \opt{language}
%     \item[csquotes] for language-specific quotations marks
%     \item[ziffer] only loaded for german documents, sets comma as decimal seperatior
%     \item[todonotes] loaded depending on \opt{todos}
%   \end{packages}
%
% \subsection{Pre-configured, but not loaded Packages}
%   These packages are coonfigured by the class to work in a cooperative way. The
%   user must load them manually in this preable via |\usepackage|\marg{pkg-name},
%   as loading them allways bears additional, unnecicary overhead.
%   \begin{packages}
%     \item[biblatex] create a bibliography
%     \item[siunitx] use units in text and equations
%     \item[listings] typset sourcecode snippets
%     \item[csvsimple] import csv-files into tables
%     \item[pgfplots / tikz] A powerfull package for drawing and plotting data
%     \item[circuitikz] A TikZ libary for drawing circuits
%   \end{packages}

%\section{Implementation}
%
%\iffalse docstrip-guard
%&lt;*article|report|standalone&gt;
%\fi
%
% \subsection{Internal commands}
%   \begin{macro}{\HsHClassName}
%     The classname of specific class is stored in the |\HsHClassName| which gets used
%     throuout the code.
%    \begin{macrocode}
\let\HsHClassName\@currname
%    \end{macrocode}
%   \end{macro}
%
%   There is also a second macro |\HsHClassName@ParrentClass| which stores the parrent
%   classes name.
%    \begin{macrocode}
\def\HsHClassName@ParrentClass{%
%&lt;article&gt;  scrartcl%
%&lt;report&gt;  scrreprt%
%&lt;standalone&gt;  standalone%
}
%    \end{macrocode}
%
%
% \subsection{Option handeling}
%   The options are handled using featues provieded by the |KOMA|-Script ecosystem.
%   To get access to this the \pkg{srcbase} package is loaded.
%    \begin{macrocode}
\RequirePackage{scrbase}
%    \end{macrocode}
%
%   We also require some packages for some of the option, these are loaded next.
%    \begin{macrocode}
\RequirePackage{setspace}
%    \end{macrocode}
%
%   A new familiy of keys is created and shared by all elelments of this project.
%   For that the |\DefineFamily| macro is used. The familiy name is \emph{HsH},
%   matching the usual prefixes.
%    \begin{macrocode}
\DefineFamily{HsH}
%    \end{macrocode}
%   Additionally each class-file represents a member in the family. This is defined
%   using the |\DefineFamilyMember| macro. It's optional argument is set to the current
%   filename by default, so we do not need to specify it, just the family name to
%   attatch it to.
%    \begin{macrocode}
\DefineFamilyMember{HsH}
%    \end{macrocode}
%
%   \begin{macro}{\HsH@Options@PassToParrent}
%     To be able to pass options to the parrent class wehre needed easiely, a command is
%     defined. It also issues a log-message.
%    \begin{macrocode}
\newcommand{\HsH@Options@PassToParrent}[1]{%
  \ClassInfoNoLine{\HsHClassName}{passing option to parrent class: #1}%
  \PassOptionsToClass{#1}{\HsHClassName@ParrentClass}%
}
%    \end{macrocode}
%   \end{macro}
%
%   \begin{macro}{\HsH@Options@DeclareAlias}
%     It is also usefull to have shot-versions of options. The following commands makes
%     it easy to decalare these.
%    \begin{macrocode}
\newcommand{\HsH@Options@DeclareAlias}[3][HsH]{%
  \DeclareOption{#2}{\FamilyExecuteOptions{#1}{#3}}%
}
%    \end{macrocode}
%   \end{macro}
%
%   \begin{option}{fontfamily}
%     The first option to be defined is \opt{fontpamily}. It's defined as a
%     \emph{Numerical} key so that it can accept multiple options and map them to a
%     switch case.
%    \begin{macrocode}
\DefineFamilyKey{HsH}{fontfamily}{
  \begingroup
  \FamilySetNumerical{HsH}{parskip}{@tmp}{%
    {sans}{0}, {sans-serif}{0},%

%     Unknown options will be passed to the parent class. For that a |@else@| key is

  fontfamily=sans-serif,
%&lt;*!standalone&gt;
  fontsize=11pt,
  language=ngerman,
%&lt;article&gt;  parskip=never+,

  linespacing=single,
  headheight=2.15\baselineskip,

  margin=0.25cm,
  multi=tikzpicture,
  multi=circuitikz,
%&lt;/standalone&gt;
}
%    \end{macrocode}
%
%     Now we can process the options for the |HsH| familiy.
%    \begin{macrocode}
\FamilyProcessOptions{HsH}\relax
%    \end{macrocode}
%
%   \subsubsection{Loading the parrent class}
%    \begin{macrocode}
\LoadClass{\HsHClassName@ParrentClass}
%    \end{macrocode}
%
%
% \subsection{Package loading}
%   The clases load and configure some common packages to reduce the needed amount of
%   boilderplate code in your preamble.
%
%   Additionally there are settings provided for packages that are used more rarly, but
%   will be set up correctly if you decide to load them via |\usepackage{}|.
%
%   \subsubsection{Ensuring German works}
%     With modern LaTeX systems the encoding of inputfiles is UTF-8 by default, so the
%     \pkg{inputenc} package is no longer requried. Should the user still use a old
%     setup or use a different encoding, he is responsible for loading \pkg{inputenc}
%     himself.
%
%     The font-encoding for the pdf file is also set up to allow for the full european
%     characterset.
%    \begin{macrocode}
\RequirePackage[T1]{fontenc}
\RequirePackage{type1ec}
%    \end{macrocode}
%
%     To ensure localised translations of all displayed text automatically dependign on
%     the user-selected \opt{language}, the \pkg{babel} package is loaded. This also
%     allowes for the use of the |\iflanguage| command, which is relevant later.
%    \begin{macrocode}
\RequirePackage[main=\HsH@opt@language]{babel}
%    \end{macrocode}
%
%     Quotationsmarks are also very different between languages, so the following
%     ensures the correct style for the correct language.
%    \begin{macrocode}
\RequirePackage[autostyle=true]{csquotes}
\MakeOuterQuote{"}
%    \end{macrocode}
%
%     German uses a comma as the decimal separator, which collides with \LaTeX{}s
%     default english setting of using the comma as a thousands separator and therefore
%     replacing it with some whitespace on printed version. Luckily loading the
%     \pkg{ziffer} package sets this up to match the german standart.
%    \begin{macrocode}
\iflanguage{ngerman}{\RequirePackage{ziffer}}{}
%    \end{macrocode}
%
%
%   \subsubsection{Generally usefull packages}
%
%     We load \pkg{hyperref} for clickable links, a interacitve document outline
%     in the PDF and configure it to write meta-date to the PDF.
%    \begin{macrocode}
%&lt;*!standalone&gt;
\RequirePackage[hidelinks]{hyperref} % must load before `bookmarks'
\RequirePackage{bookmark}
\AtBeginDocument{
  \hypersetup{
    pdfinfo={
      Title={\@title},
      Author={\@author},
      Subject={\@subject},
      Keywords={\@keywords}
    }
  }
}
%&lt;/!standalone&gt;
%    \end{macrocode}
%
%     The \pkg{hyperref} package has a problem when linking to images,
%     clicking a linke to one leads to the \emph{bottom} of the float
%     (where the caption is located), instead of to the \emph{top}.
%     Loading the \pkg{captoion} package with the \opt{hypercap} option
%     fixes that.
%    \begin{macrocode}
\RequirePackage[hypcap=true]{caption}
%    \end{macrocode}
%
%     To display images (mostly through the |\includegraphics| command)
%     we require the \pkg{graphicx} package.
%    \begin{macrocode}
\RequirePackage{graphicx}
%    \end{macrocode}
%
%     The \pkg{ams} family of packages containes a wide collection of math
%     related commands that are generally usefull.
%    \begin{macrocode}
\RequirePackage{amsmath,amssymb,amsfonts}
%    \end{macrocode}
%
%     The \pkg{enumitem} package is very helpful for defining lists of any kind.
%     We use it to provide a checklist implementation.
%    \begin{macrocode}
\RequirePackage{enumitem}
%    \end{macrocode}
%
%     The \pkg{todonotes} package is greate for anotation, but extremly expensive on
%     compiletime. So we load it only if the user requests it. Also its commands are
%     stubed, so that they can be left in the sourcecode and jut not output anything.
%    \begin{macrocode}
\if@todos
  \PassOptionsToPackage{svgnames}{xcolor}
  \AtEndOfClass{\RequirePackage{xcolor}}
  \RequirePackage[
    textsize=small,
    figwidth=.6\textwidth
  ]{todonotes}
  \setuptodonotes{
    backgroundcolor=orange!20!white,
    linecolor=orange,
    bordercolor=orange!60!white,
  }
\else
  \newcommand{\listoftodos}[1]{}
  \newcommand{\todo}[2][]{}
  \newcommand{\missingfigure}[2][]{}
\fi
%    \end{macrocode}
%
%     Some more micalanious packages:
%    \begin{macrocode}
\RequirePackage{xcolor}
%    \end{macrocode}
%
%   \subsubsection{Options for packages that could be loaded by the user}
%     Some package are not always needed and potentially heavy to load in by default.
%     But its still usefull to set default options for these packagese.
%
%     These differ from the settings provided in |HsH-classes.cfg| in that they are
%     defaults that apply allway and not user-configurable preferences which are user
%     or even project specific.
%
%     For the \pkg{bibtex} we ensure the \emph{biber} backend is selcted, which matches
%     the settings in |.latexmkrc|.
%    \begin{macrocode}
%&lt;*article|report&gt;
\PassOptionsToPackage{
  backend=biber,
  bibwarn=true,
  url=true,
  isbn=false,
}{biblatex}
\AddToHook{package/biblatex/after}{
  \renewcommand*{\mkbibacro}[1]{\MakeUppercase{#1}}
}
%&lt;/article|report&gt;
%    \end{macrocode}
%
%     For \pkg{bibtex} we load the free-stadnding units, mostly for backwards compatibility.
%     We also ensure german language specific settings are applyed.
%    \begin{macrocode}
\PassOptionsToPackage{free-standing-units}{siunitx}
\AddToHook{package/siunitx/after}{
  \sisetup{
    tight-spacing=true,
    per-mode=symbol,
    exponent-mode=engineering,
    round-mode=places,
    round-precision=3,
  }
  \iflanguage{ngerman}{
    \sisetup{output-decimal-marker={,}}
  }{}
}
%    \end{macrocode}
%
%     For better compatibility with the \pkg{listings} package we load the
%     \pkg{scrhack} package. We also pass some configurations to if if it gets loaded.
%    \begin{macrocode}
\RequirePackage{scrhack}
\AddToHook{package/listings/before}{\RequirePackage{xcolor}}
\AddToHook{package/listings/after}{
  \lstset{
    commentstyle=\color{gray},

    showstringspaces=false,

    escapeinside={(*@}{@*)},
  }

  }{}
}
%    \end{macrocode}
%
%     The \pkg{csvsimple} is helpfull wehn wanting to import CSV-files and display them as tables.

%    \end{macrocode}
%
%     \pkg{pgfplots} is a powerfull package for ploting data.
%    \begin{macrocode}

  }
}
%    \end{macrocode}
%
%     For other packages we provide the settings more as a recomendation of what is
%     usefull. As the user might want to change these, we outsource this to a seperat file
%     and input it |\AtBeginDocument|. That way the user can just replace the file with his
%     custom version.
%    \begin{macrocode}

  }
  \makeatother
}
%    \end{macrocode}
%
% \subsection{Custom commands}
%
%   \subsubsection{Document seperation commands}
%     The following commands are only defnied for \cls{book} type classes by default.
%     But they are also usefull for the \cls{report} class, so we define them in that case.
%    \begin{macrocode}
%&lt;*report&gt;
%    \end{macrocode}
%
%     \begin{macro}{\if@mainmatter}
%       We define a switch which stores if the document is currently at a mainmatter

%   \subsubsection{The Logo for Hochschule Hannover}
%     The following macros are responsible for creating the logo. They load a specific
%     page of a PDF file and siplay it.
%
%     \begin{macro}{\HsHlogoPath}
%       This macro contains the path to load the PDF from. It defaults to
%       |HSH-Logo.pdf|, which is provieded by this project inside the |scr/| folder.
%    \begin{macrocode}
\newcommand{\HsHlogoPath}{HSH-Logo.pdf}
%    \end{macrocode}
%     \end{macro}
%
%     \begin{macro}{\HsHlogoPage}
%       This macro stores the page to use from the PDF. It will be set via the
%       documentoption \opt{faculty}.
%    \begin{macrocode}
\newcommand{\HsHlogoPage}{\HsH@opt@faculty}
%    \end{macrocode}
%     \end{macro}
%
%     \begin{macro}{\includeHsHlogohere}
%       Calling this macro produces the logo in-place. You can specify the width as an
%       optional argument. The default is $5\,\mathrm{cm}$. \par
%       If the file provided via \cmd{\HsHlogoPath} doesn't exist, the command will
%       produce an error.
%    \begin{macrocode}
\newcommand{\includeHsHlogohere}[1][5cm]{
  \IfFileExists{\HsHlogoPath}{
    \includegraphics[width=#1,page=\HsHlogoPage]{\HsHlogoPath}
  }{
    \ClassError{\HsHClassName}{\HsHlogoPath\space not found!}{
      The HsH Logo is necasary for the titlepage! Try putting it next to your source file or use \HsHlogoPath to define the file location
    }
  }
}
%    \end{macrocode}
%     \end{macro}
%
%   \subsubsection{Title matters}
%    \begin{macrocode}
%&lt;*article|report&gt;
%    \end{macrocode}
%
%     The following commands relave to the creation of the titlepage. They Implement
%     how the user can define the differnt datafields.
%     \smallskip
%
%     \begin{macro}{\title}
%       We redefine the |\title| command to take a optional argument. This is stored in
%       the additional |\@shorttitle| macro.
%    \begin{macrocode}
\renewcommand{\title}[2][]{
  \gdef\@title{#2}
  \gdef\@shorttitle{#1}
}
%    \end{macrocode}
%     \end{macro}
%
%     \begin{macro}{\@shorttitle}
%       This new macro stores a short version of the title. This will be used in places
%       where the fill title might overflow the availabel space.
%    \begin{macrocode}
\def\@shorttitle{\@empty}
%    \end{macrocode}
%     \end{macro}
%
%     \begin{macro}{\gdef@with@and@as@comma}
%       First we define a helpermacro that will fill a given macro while treating the
%       |\and| command as a comma. This is needed for |\author| and |\matrikelnr| where
%       we later treat them as comma-seperated lists when the titlepage gets constructed.
%    \begin{macrocode}
\def\gdef@with@and@as@comma#1#2{{\def\and{,}\xdef#1{#2}}}
%    \end{macrocode}
%     \end{macro}
%
%     \begin{macro}{\author}
%       We redefine the |\author| command so that it sets |\@author|, but allowing for both
%       comma and |\and| to be used as a seperator.
%    \begin{macrocode}
\renewcommand{\author}[1]{\gdef@with@and@as@comma\@author{#1}}
%    \end{macrocode}
%     The |\@author| macro is also set to |\@empty|, this makes it easier to handle it
%     later.
%    \begin{macrocode}
\let\@author\@empty
%    \end{macrocode}
%     \end{macro}
%
%     \begin{macro}{\matrikelnr,\@matrikelnr}
%       These macros set and store the matrikel-number (or set of numbers), which will
%       be printed on the titlepage.
%    \begin{macrocode}
\newcommand{\matrikelnr}[1]{\gdef@with@and@as@comma\@matrikelnr{#1}}
\def\@matrikelnr{\@empty}
%    \end{macrocode}
%     \end{macro}
%
%     \begin{macro}{\professor,\firstexaminer,\secondexaminer,\@professor,\@firstexaminer,\@secondexaminer}
%       These three macros-groups give options to the user to print peoples names on
%       the titlepage, who are relevant to the document, but not the author.
%    \begin{macrocode}
\newcommand{\professor}[1]{\gdef\@professor{#1}}
\def\@professor{\@empty}
\newcommand{\firstexaminer}[1]{\gdef\@firstexaminer{#1}}
\def\@firstexaminer{\@empty}
\newcommand{\secondexaminer}[1]{\gdef\@secondexaminer{#1}}
\def\@secondexaminer{\@empty}
%    \end{macrocode}
%     \end{macro}
%
%     \begin{macro}{\keywords,\@keywords}
%       The macro-group defines and holds keywords which describe the document. They
%       are used when printing the abstract as well as in the PDF's meta-data.
%    \begin{macrocode}
\newcommand{\keywords}[1]{\gdef\@keywords{#1}}
\def\@keywords{\@empty}
%    \end{macrocode}
%     \end{macro}
%
%    \begin{macrocode}
%&lt;/article|report&gt;
%    \end{macrocode}
%
%   \subsubsection{Commands for document writing}
%
%     \begin{macro}{\declarationofauthorship}
%       The declatation of authorship is not relevant for the \cls{standalone} varaiant.
%    \begin{macrocode}
%&lt;*!stadnalone&gt;
%    \end{macrocode}
%       The \pkg{pgffor} package is requried to handle the loope over the list of authors.
%    \begin{macrocode}
\RequirePackage{pgffor}
%    \end{macrocode}
%       Now the command is defined. It takes a optional argument which defaults to \opt{b}.
%    \begin{macrocode}
\newcommand{\declarationofauthorship}[1][b]{
%    \end{macrocode}
%       First the argument is passed and an error raised for invalid arguments. Passing
%       in \opt{b} will push the declatarion to the bottom of the page and add a
%       horizontal line. PAssing \opt{t} simply adds some space.
%    \begin{macrocode}
  \if#1b
    \vspace*{\fill}
    \hrule
  \else\if#1t
    \vspace*{2em}
  \else
    \ClassError{\HsHClassName}{Wrong Parameter for `\declarationofauthorship'}{
      `\string\declarationofauthorship' only accepts `t' and `b' as parameters.
    }
  \fi\fi
%    \end{macrocode}
%       Now the actuall declatarion can be constructed. It uses the text from |\decofauthname|
%       and |\decofauthtext|.
%    \begin{macrocode}
  \vskip 3em
  {\centering\bfseries\usekomafont{section}{\decofauthname}\par}
  \vskip 3em
  \decofauthtext\par
%    \end{macrocode}
%       The last step is to loop over all authors by reading |\@author| and creating a
%       signature box for each one. |\thanks| also needs to be cleared, as a footnote
%       wouldn't make sense here.
%    \begin{macrocode}
  \begingroup
    \renewcommand{\thanks}{\sbox0}
    \raggedleft
    \foreach \tmp@ in \@author {
      \if\tmp@\empty\else
        \hskip 1em \parbox{4cm}{
          \vskip 4em
          \hrule\vskip 4pt
          \raggedleft\footnotesize\tmp@
        }%
      \fi
    }\par
  \endgroup
}
%    \end{macrocode}
%     \end{macro}
%
%     \begin{macro}{\if@singleauthor}
%       To ensure |\decofauthtext| is preperly spelled for one or multiple authors, we
%       define a conditional that holds this information. Additionally we check the
%       number of authors |\AtBeginDocument| and store it.
%    \begin{macrocode}
\newif\if@singleauthor
\AtBeginDocument{
  \begingroup
    \newcount\count@
    \count@=\z@
    \@for\tmp@:=\@author\do{\advance\count@\@ne}
    \ifnum\count@&gt;\@ne\global\@singleauthorfalse\else\global\@singleauthortrue\fi
  \endgroup
}
%    \end{macrocode}
%     \end{macro}
%
%     \begin{macro}{\ifsingleauthor}
%       A macro to simply act on this condition is also provided. It will be used in
%       text-definitions later on.
%    \begin{macrocode}
\newcommand{\ifsingleauthor}[2]{\if@singleauthor#1\else#2\fi}
%    \end{macrocode}
%     \end{macro}
%
%     \begin{macro}{\declarationAuthorship}
%    \begin{macrocode}
\def\declarationAuthorship{%
  \ClassWarning{\HsHClassName}{%
    Command \string\declarationAuthorship\space is deprecate.\MessageBreak
    Replace it with \string\declarationofauthorship.
  }%
  \declarationofauthorship%
}
%&lt;/!stadnalone&gt;
%    \end{macrocode}
%     \end{macro}
%
%     \begin{environment}{checklist}
%       Using the \pkg{enumitem} package, we define a hepful enviroment for creation
%       checklist.
%    \begin{macrocode}
\newlist{checklist}{itemize}{2}
\setlist[checklist]{label=$\square$}
%    \end{macrocode}
%     \end{environment}
%
%   \subsubsection{Micalanious commands}
%     \vspace{-1\baselineskip}
%     \paragraph{Utillity commands}
%     For writing absolout values, we provide the \cmd{\abs\marg{equ}} command, which
%     puts groable, vertical bars on both sides of the equation inside.
%    \begin{macrocode}
\newcommand{\abs}[1]{\ensuremath{\left\vert#1\right\vert}}
%    \end{macrocode}
%
%     \paragraph{Configuring mathmode-indices}
%     The only hard requirements for documents writing on Hochschule Hannover is, that
%     the indices in mathematic formulas must be typset in an upright ("steil") font,
%     not the default kursive font. We configure this by first defining a macro to
%     replace the default \cmd{\sb} macro. We can than assign this to |_|. For that to
%     work we need to change its catcode to make it modifyable.
%     \begin{note}
%       You can allways use \cmd{\sb} to use the original behaviour for special cases.
%     \end{note}
%    \begin{macrocode}
\def\@subinrm#1{\sb{\mathrm{#1}}}
{\catcode`\_=13 \global\let_=\@subinrm}
%    \end{macrocode}
%
%     \begin{macro}{\upsubscripts}
%       Now we can define a command to activate this new behavior by changing the catcode
%       of |_| to 13, which makes it a normal macro.
%    \begin{macrocode}
\newcommand\upsubscripts{\catcode`\_=12}
%    \end{macrocode}
%     \end{macro}
%
%     \begin{macro}{\normalsubscripts}
%       To switch back we simply need to reset the catcode of |_| back to the original,
%       which makes it a buildin operator with the default behavior.
%    \begin{macrocode}
\newcommand\normalsubscripts{\catcode`\_=8}
%    \end{macrocode}
%     \end{macro}
%
% \subsection{Document setup}
%   The following sets up the look and feel of the documents using this classe. All
%   configuration and stylin is done here.
%
%   \subsubsection{Fonts and text styling}
%    \begin{macrocode}
\RequirePackage{lmodern}
%    \end{macrocode}
%
%   \subsubsection{Page layout}
%    \begin{macrocode}

\fi
%&lt;/!standalone&gt;
%    \end{macrocode}
%
%   \subsubsection{Styling \LaTeX{} default constucts}
%
%     \vspace{-1\baselineskip}
%     \paragraph{Floats}\vspace{-1\baselineskip}
%    \begin{macrocode}
%&lt;*!standalone&gt;
%    \end{macrocode}
%     Floats should alwasy prefere the \emph{here} placement, than the \emph{top} of
%     the following page.
%    \begin{macrocode}
\renewcommand{\fps@figure}{h!t}
\renewcommand{\fps@table}{h!t}
%    \end{macrocode}
%
%     Floats should be centered by default and the width of the caption box is limited.
%    \begin{macrocode}
\g@addto@macro\@floatboxreset\centering
\setcapwidth{0.8\textwidth}
%    \end{macrocode}
%
%     The names of floating enviroments are redefined to show abreviations only.
%    \begin{macrocode}
\defcaptionname{english}\figurename{Fig.}
\defcaptionname{german,ngerman}\figurename{Abb.}
\defcaptionname{english}\tablename{Tab.}
\defcaptionname{german,ngerman}\tablename{Tab.}
%    \end{macrocode}
%
%     For subfigures we need to define a name used in autoreferences.
%    \begin{macrocode}
\AtBeginDocument{
  \makeatletter
  \@ifpackageloaded{subfigure}{
    \let\subfigureautorefname\figureautorefname
  }{}%
  \makeatother
}
%    \end{macrocode}
%
%    \begin{macrocode}
%&lt;/!standalone&gt;
%    \end{macrocode}
%
%     \paragraph{Lists}
%     For unordert liste the markers are redefined to look a littel nicer.
%    \begin{macrocode}
\renewcommand{\labelitemi}{\raisebox{.3ex}{\scalebox{0.7}{$\bullet$}}}
\renewcommand{\labelitemii}{\raisebox{.3ex}{\scalebox{0.7}{$\circ$}}}
\renewcommand{\labelitemiii}{\raisebox{-.1ex}{\scalebox{1.3}{$\cdot$}}}
\renewcommand{\labelitemiv}{\raisebox{.1ex}{-}}
%    \end{macrocode}
%
%     \paragraph{Abstract}
%     We define some custom behavior for the abstract. Its typeset as a quote, so
%     its a little smaller than the rest of the text. We also indent the heading to
%     match that.
%    \begin{macrocode}
%&lt;*!standalone&gt;
\renewenvironment{abstract}{
  \begingroup
%&lt;article&gt;    \edef\raggedsection{\raggedsection%

}
%&lt;/!standalone&gt;
%    \end{macrocode}
%
%     \paragraph{Misc}
%     We activae one of the commands defined above to make math-indices upright by
%     default.
%    \begin{macrocode}
\upsubscripts
%    \end{macrocode}
%
%     We want a ragged botton instead of spreading the paragraphs over the page.
%    \begin{macrocode}
\raggedbottom
%    \end{macrocode}
%
%   \subsubsection{Header and footer}
%
%    \begin{macrocode}
%&lt;*article|report&gt;
%    \end{macrocode}
%
%     The header and footer are styled using the low-level commands provided by the
%     \KOMAScript{} package \pkg{scrlayer-scrpage}. We also disable the ruler shown
%     in the heading of \opt{draft} mode.
%    \begin{macrocode}
\RequirePackage{scrlayer-scrpage}
\FamilyOptions{KOMA}{headsepline,singlespacing=true}
\let\layercontentsmeasure\relax
%    \end{macrocode}
%
%     First we define the new pagestyle |HsHheadings|.
%    \begin{macrocode}
\newpagestyle{HsHheadings}{
  {
    \parbox[b]{\sls@headwidth}{
      \LaTeXraggedright
