\section{Introduction}
To conduct exams, we occasionally require seating plans.
Over time, we have accumulated several such plans in the form of TikZ-supported
\LaTeX\ files.
Depending on the number of students in an exam—and how high we assess the
risk of attempted cheating—we apply different placement schemes, which
requires adapting the files accordingly.
Moreover, we are sometimes assigned new rooms for which no seating plans exist yet.

This was the motivation for developing the \thepkg\ package. It \ldots
\begin{itemize}%[itemsep=0pt]
  \item enables quick and easy creation of seating plans;
  \item separates seat layout from the placement scheme;
  \item offers a set of standard placement schemes;
  \item includes a number of predefined rooms with seat layouts;
  \item allows for \emph{ad hoc} creation of new rooms and placement schemes.
\end{itemize}

\section{Dependencies}
The \thepkg\ package works only with Lua\LaTeX\ and requires a sufficiently
modern \LaTeX\ version, at least from July 2022.
It loads the following packages:
\begin{itemize}%[nosep]
  \item \pkg{etoolbox} 
  \item \pkg{luacode}
  \item \pkg{tikz}
\end{itemize}
These packages are available in all major \TeX\ distributions and themselves
depend on other packages.
In particular, \pkg*{tikz} loads the \pkg{xcolor} package, whose color definitions
are also used by \thepkg.

\section{Seat Layout}
\label{sec:layout}
The package is loaded as usual with
\cs{usepackage}\oarg{options}\{\thepkg\}

This allows the layout of the seats—i.e., their arrangement in the room—
to be defined right away. Seat assignment is done later;
see Section~\ref{sec:seat-assignment}.

\subsection{Class Options}
\label{sec:class-options}
The use of the option \option{room} distinguishes between two fundamental use cases:
\begin{options}
  \keyval{room}{Room} This option key should be used if the desired room
  is already predefined.
  \keyval{layout}{institution}\Default{tu-chemnitz}
  The data for the predefined rooms is read
  from \code{seatingchart-}\meta{institution}\code{.sc}.
  This key can be used if own predefined rooms have been declared, see
  Section~\ref{sec:new-rooms}. 
\end{options}
If the room is not already known, it can also be created \emph{ad hoc}, whereas
several key–value options are required to describe the layout: 

\begin{options}
  \keychoice{shape}{rectangle,arc}\Default{rectangle}
  Specifies whether the seating layout is rectangular (\choices{rectangle}) or curved (\choices{arc}).%
  \footnote{For example, room A10.316 at TU~Chemnitz uses an arc layout.}

  \keyval{rows}{number}\Default*!{}\vspace{-.3\baselineskip}
  \keyval{seats per row}{number}\Default!{}
  Defines the number of seat rows and seats per row. The maximum number must always be specified here.
  For incomplete rows, seats will be removed later, but no additional seats can be added that lie outside
  the originally defined layout area.
  \textbf{Note:} Aisles between blocks of seats must be counted here as seats as well.
\end{options}

If you specify \textbf{both} the \option*{room} key \textbf{and} one of the keys
\option*{rows} or \option*{seats per row} in the class options, the result is undefined.
A warning will be issued in that case.\medskip

All further class options define the visual representation of the room layout.
They can also be set later using \cs{scConfig}; see Section~\ref{sec:late-options}.

\begin{options}
  \keybool{blackboard}\Default{false}
  Draws a blackboard.

  \keyval{seat distance}{distance}\Default{2pt}
  Distance between seats. This also determines the row spacing.
  If you want these two values to differ, you must use the following keys:

  \keyval{seat neighbor distance}{Distance}\Default*{2pt}\vspace{-.3\baselineskip}
  \keyval{row distance}{distance}\Default{2pt}

  \keychoice{rownumbers}{none,left,right,both}\Default{none}
  For rectangular layouts, defines whether to display row numbers on the left, right, or both sides.
  Counting starts at the front (blackboard side).\newline
  \emph{Note:} For arc-shaped layouts, this function is currently not implemented.

  \keyval{rownumber distance}{distance}\Default{2pt}
  Distance between the row number and the outermost seats,
  if \option*{rownumbers} is not \code{none}.

  \keyval{empty seat background color}{color}\Default*{lightgray!20}\vspace{-.3\baselineskip}
  \keyval{empty seat border color}{color}\Default*{lightgray}\vspace{-.3\baselineskip}
  \keyval{assigned seat background color}{color}\Default*{lightgray!30}\vspace{-.3\baselineskip}
  \keyval{assigned seat border color}{color}\Default{black}
  Defines background and border colors for empty or assigned seats.
  The syntax of color names follows the specification of the \pkg*{xcolor}
  package.
  If the seats should not be differentiated by color, the keys
  \keyval-{seat background color}{color}\Default*\vspace{-.3\baselineskip}
  \keyval-{seat border color}{color}\Default
  can also be used.
  \keyval{assigned seat label font}{font command}\Default*{\cs*{small}}\vspace{-.3\baselineskip}
  \keyval-{assigned seat label color}{color}\Default{black}
  Sets the size and color of the seat label.
\end{options}

\subsection{Late Option Selection}
\label{sec:late-options}
\begin{commands}
  \command{scConfig}This command can be used to set all keys mentioned in
  Section~\ref{sec:class-options}, except for
  \option{room}, \option{shape}, \option{rows}, and \option{seats per row},
  outside of the \cs*{documentclass} options.
\end{commands}

\subsection{Modifying the Seat Layout}
\label{sec:modify-layout}
Often, not all seats are present in every row.
This is already taken into account when specifying a predefined room,
but it may still be necessary to remove individual seats — for instance,
if a folding seat is broken.

When creating a custom layout, such modifications are typically required.
For this purpose, \pkg\ provides the following commands:
\begin{commands}
  \command{scRemoveSeatAt}[\marg{row}\marg{seat number}]
  Removes seat \meta{seat number} in row \meta{row} from the layout.
  The values refer to the original layout and are unaffected by previously removed seats.
  If \meta{seat number} is negative, counting starts from the right.

  \command{scRemoveSeats}[\marg{list}]
  Removes all seats listed in the comma-separated \meta{list}, where each entry
  is of the form \code{\{\meta{row},\meta{seat number}\}}.
  As with \cs*{scRemoveSeatAt}, row and seat numbers refer to the original layout.
  In the following example, the first three seats on the left and the first seat
  on the right in the first row are removed: \vspace{-.3\baselineskip}
  
  \begin{example}[code-only]
    \scRemoveSeats{{1,1},{1,2},{1,3},{1,-1}}
  \end{example}\vspace{-1.3\baselineskip}

  \command{scSetAisle}[\Oarg{\meta{start row}-\meta{end row}}\marg{seat number}]
  Inserts an aisle at the position of \meta{seat number} through all rows.
  Use the optional argument if the aisle should not span all rows.

  For horizontal aisles (which split a seat block into front and back instead of
  left and right), 
  please use \cs*{scRemoveSeats}.

  While this is also possible for vertical aisles, automatically generated
  seating schemes may treat aisles created via \cs*{scSetAisle} differently
  than those created with \cs*{scRemoveSeats}.
\end{commands}

\subsection{Output}
\label{sec:drawing}

\begin{commands}
  \command{scDrawSeating}[\Oarg{seat width=\meta{width}, seat
    height=\meta{height}}]  
  Renders the seating plan. \thepkg\ attempts to calculate the seat dimensions
  so that the available space for the complete plan is fully utilized.
  Since this may not always meet all needs, the optional argument allows
  the width and height of the seats on the plan to be adjusted individually.

\end{commands}

The following example shows the code and the result for a simple seating layout
with a central aisle and two missing seats in the first row.
\begin{example}[compile,program=lualatex,pages=1,add-frame,code-sep=\bigskip,graphics={scale=.25}]
  \documentclass{article}
  \usepackage[shape=rectangle, rows = 9, seats per row=15]{seatingchart}
  \begin{document}
    \scSetAisle{8}
    \scRemoveSeats{{1,1},{1,2}}
    \scDrawSeating
  \end{document}
\end{example}

\section{Seat Assignment}
\label{sec:seat-assignment}

\subsection{Parameters for Constructing Assignment Schemes}
\label{sec:constr-scheme}

A seating plan is only partially useful without indicating which seats are occupied.
In \thepkg, seat assignment is handled via assignment schemes.
To define such a scheme, the command

\begin{commands}
  \command{scSeatingScheme}[\oarg{key list}\marg{name}] \vspace{-1.7\baselineskip}
  \command{scSeatingScheme}[\sarg\oarg{key list}\marg{pattern}]
The mandatory argument, in the standard version of the command,
is a name for a predefined seating scheme (see Section~\ref{sec:defined-schemes}).
In the starred version, a string of "`\code{X}"’ and "`\code{-}"’ is passed,
describing (the beginning of) a row assignment pattern, where
"`\code{X}"’ denotes an occupied seat and "`\code{-}"’ an empty one.
If the string is shorter than the number of seats in a row, it will be repeated.

For example,
\begin{example}[code-only]\vspace{-1.3\baselineskip}
  \scSeatingScheme*{X--}
\end{example}\vspace{-1.3\baselineskip}
marks every third seat as occupied.

The optional argument accepts a list of key–value pairs that control the remaining
settings of the assignment scheme.
These are especially important in the starred variant but may also be used
in the standard one.

\begin{options}
  \keyval-{row sep}{number}\Default{2}
  Specifies how many rows should lie between two occupied rows.

  \keyval-{start row}{row}
  First row to be included in the assignment.

  \keyval-{end row}{row}
  Last row to be included in the assignment.

 \keyval-{row restart after}{number}\Default
  Resets the seat pattern after \meta{number} rows. This allows for alternating
  row spacing; see the example in Section~\ref{sec:ex:own1}.

  \keyval-{aisle counts}{number}\Default{1}
  Specifies how many seats wide an aisle should be considered. This allows
  for wider aisles to be taken into account.

  \keybool{aisle restarts scheme}\Default{false}
  Restarts the scheme after an aisle. In that case, the \option*{aisle counts}
  key has no effect.

  \keybool{ignore aisle}\Default*{false}\vspace{-.3\baselineskip}
  \keybool{ignore removed seats}\Default{false}
  When determining seat numbers (used e.g. in labels; see
  Section~\ref{sec:seat-label}), aisles and removed seats are normally counted.
  This ensures that seat numbers are consistent across rows (in rectangular layouts).
  If one of these keys is set, aisles or removed seats are no longer counted.
  This is particularly useful in curved layouts.

  \keyval{assigned seat label}{format string}\Default{m{{\,}}D}
  Specifies how assigned seats should be labeled.
  By default, this consists of the row number, a thin space,
  and a letter for the current occupied seat
  (e.g., "`3\,c"'). A number of other formats can be configured;
  see Section~\ref{sec:seat-label} for details.
\end{options}

\command{scConfigScheme\marg{key list}}
Sets keys just like the optional argument of \cs*{scSeatingScheme},
but does not assign seats.
\end{commands}

Key values set by \cs*{scSeatingScheme} or \cs*{scConfigScheme}
remain in effect until they are explicitly redefined.
  
\subsection{Predefined Seating Schemes}
\label{sec:defined-schemes}
The \thepkg\ package defines a set of predefined seating schemes.
Some of them also have alternative names.
\begin{options}
  \opt{1x1}
  Every seat is marked.\newline Alternative name: \option{all}

  \opt{2x2}
  One empty seat and one empty row between two occupied ones.\newline Alternative name: \option{simple}

  \opt{2x2-}
  One empty seat between two occupied ones. After a single empty row,
  \emph{two} rows with occupied seats follow.
  This scheme allows the largest number of students in a room during an exam
  while still maintaining minimal lateral distance and enabling supervision
  to reach every student (from the front or the back).\newline Alternative name: \option{dense}

  \opt{2x3}
  Occupied seats have two empty seats between them laterally,
  and one empty row between occupied rows.
  This is considered the preferred default scheme for exams in our group.\newline Alternative name: \option{sixpack}

  \opt{2x3-}
  Rows are occupied as in \option{2x2-}, but the lateral spacing
  within an occupied row is two seats.

  \opt{2x4}
  Occupied seats have three empty seats between them laterally,
  and one empty row between occupied rows.

  \opt{3x4}
  Occupied seats have three empty seats between them laterally,
  and two empty rows between occupied rows.
\end{options}

\subsection{Seat Labeling}
\label{sec:seat-label}
The labeling of assigned seats can be done in various ways, controlled by
assigning a format string to the key \option{assigned seat label}.
Four counters are available for this purpose:
\begin{itemize}
\item absolute row: the row number in the seat layout
\item occupied row: the number of the \emph{assigned} row.
  Rows without any assigned seats are skipped.
\item absolute seat number: the seat number in the seat layout.
  Whether removed seats are counted depends on the value of
  \option*{ignore removed seats}.
\item occupied seat number: the number of the \emph{assigned} seats.
  Unassigned seats are skipped in this count.
\end{itemize}
Each of these counters can be formatted differently.
For this, the format string uses format specifiers listed in the following table:\medskip

\begin{tabular}{llccccc}\hline
  \textbf{\sffamily Counter}&\textbf{\sffamily Description}&\multicolumn{5}{c}{\textbf{\sffamily Rendered as\ldots}}\\
      &&\rotatebox{90}{Arabic numeral}&\rotatebox{90}{lowercase letter}&\rotatebox{90}{uppercase letter}&
 \rotatebox{90}{lower Roman numeral}&\rotatebox{90}{upper Roman numeral}\\\hline
  absolute row&\emph{based on seat layout}&\code{m}&\code{a}&\code{A}&\code{y}&\code{Y}\\
  occupied row&\emph{based on assigned rows}&\code{r}&\code{b}&\code{B}&\code{i}&\code{I}\\ 
  absolute seat number&\emph{based on seat layout}&\code{n}&\code{c}&\code{C}&\code{x}&\code{X}\\
  occupied seat number&\emph{based on assigned seats}&\code{s}&\code{d}&\code{D}&\code{j}&\code{J}\\\hline
\end{tabular}\medskip

\noindent
Parts of the label that should not be interpreted as format specifiers must be
wrapped in double braces: \code{\{\{\meta{protected string}\}\}}.

For example,\vspace{-1.3\baselineskip}
\begin{example}[code-only]
  \scSeatingScheme[assigned seat label=Y{{-}}D]{2x3}
\end{example}\vspace{-1.3\baselineskip}
produces the label "`III-B"' for the fourth seat (from the left) in the third
row.

\subsection{Seat List}
\label{sec:seats-list}
Especially in the context of examinations, it is useful to generate a seat list,
i.e., a tabular mapping between student and assigned seat.
In its current version, \thepkg\ does not create a \LaTeX\ table,
but it can support table generation (e.g., using \LaTeX\ or a spreadsheet application).

\begin{commands}
  \command{scSeatingList}[\oarg{input file}\marg{output file}]\vspace{-1.3\baselineskip}
  \command{scSeatingList}[\sarg\oarg{input file}\marg{output file}]
  Creates a CSV file \meta{output file} containing the labels of the assigned seats,
  one per line.\medskip

  \framebox{\parbox{\linewidth}{
    \textbf{Note!}
    The label texts written to \meta{output file} are extracted from the
    corresponding \LaTeX\ boxes, and only printable characters are included.
    When using this function, it's therefore recommended to avoid excessive
    \TeX-level formatting in the \option*{assigned seat label} format string.
  }}\medskip

  In the starred variant, each line is prefixed with the absolute coordinates
  (row, seat number, relative to the layout), comma-separated, before the label.

  If an input file is specified, its content is prepended line-by-line
  to the generated lines. For example, the input file could contain names
  and/or student IDs, which will then be matched to the assigned seats in the output.
  If there are fewer entries in \meta{input file} than assigned seats,
  the corresponding fields in the output will be left empty.
  If, on the other hand, there are more entries than available seats,
  \thepkg\ will report which entries could not be assigned a seat.
\end{commands}

\section{Examples}

To demonstrate the behavior of \thepkg, a few usage examples are documented
here.

\section{Declaration of New Rooms}
\label{sec:new-rooms}
In its current version, the \thepkg package only contains a relatively small
number of rooms at TU Chemnitz with their seating layouts. 
Users will therefore often have to create their own layouts.

In addition to the option for ad-hoc layout creation, as described in the se
ction~\ref{sec:layout}, it is also possible to extend the package itself and
create layouts for new rooms, which can then be easily accessed via the
\option{room} key. 

For this purpose, custom \code{seatingchart-*.sc} files can be created and
integrated via the \option{layout}. 
Two commands can be used in \code{seatingchart-*.sc} files:
\begin{commands}
\command{scDeclareRoom}[\marg{room name}\marg{key list}]
A new room layout is created for the room \meta{room name}.
The key list \emph{must} contain the three keys
\begin{options}
\keychoice{shape}{rectangle,arc}\Default*!{}%\vspace{-.3\baselineskip}
\keyval-{rows}{number of rows}\Default*!{}%\vspace{-.3\baselineskip} and
\keyval-{seats per row}{seats per row}\Default!{}
These keys have the same meaning as the
keys of the same name from Section~\ref{sec:layout}.
This information about the base layout \emph{must} be followed by the key
\opt{init}\Default!

The layout can then be adjusted using
\keyval-{aisle}{seat number}\vspace{-1.3\baselineskip}
\keyval{remove}{list}
These two keys function analogously to
\cs*{scSetAisle} and \cs*{scRemoveSeats}, see Section~\ref{sec:modify-layout}.
\end{options}
\begin{example}[code-only]
  \scDeclareRoom{C10.115}{
    shape=rectangle,
    rows=21,
    seats per row=35,
    init,
    aisle=18,
    remove={{1,1},{1,2},{1,3},{1,4},{1,-1},{1,-2},{1,-3},{1,-4}}
  }
\end{example}\vspace{-1.3\baselineskip}
\command{scAliasRoom}[\marg{alias}\marg{room}]
Sets \meta{alias} as a replacement name for \meta{room}.
\end{commands}
If you would like your institution's layout file to be included in the package
on CTAN, please send your file to the maintainer or initiate a pull request on 
\url{https://github.com/tuc-osg/seatingchart}.
In this case, give the file a meaningful and distinguishable name. For example,
\emph{University of Lummerland at Lummerland City}
should use \code{seatingchart-lummerland-uni-lc.sc} rather than
\code{seatingchart-lu.sc}.

\section{Limitations and Bugs}
\label{sec:bugs}
Even though the \thepkg package is in practical use, at least in our group, it
should be considered experimental. 
The \code{0} in the major version number indicates this fact.
In particular, it means that the API is still subject to change.

The package is subject to some limitations.
Whether these will be fixed in future versions is not yet known.
The package is designed for creating separate seating charts and therefore cannot be used to display multiple seating charts in one document.
Likewise, seating layouts with staggered rows cannot be displayed.

The number of predefined rooms is currently relatively small.
There are plans to include additional rooms at TU Chemnitz in future patches.
Layout files from other institutions are welcome.

Curved room layouts are problematic for smaller row lengths.
Please use GitHub for bug reports or pull requests:
