\section{Introduction}\label{intro}
The \textsf{association-matrix} package allows the convenient creation of association matrices.
The package aims to automate the generation, without the user having to manually write the table's code and have to deal with the inefficiency of copy-pasting information.
The package's interface is simple, the user needs to define the table's contents (\cref{define}) and then can generate the table (\cref{tablegen}).

Note that it is important to have \emph{every} necessary row entries and column headings defined \textbf{before} the first call to a table generation, otherwise, only a partial table will be generated.

\subsection{Association matrix}\label{association-mx}
At the author's University, it is customary for Ph.D.\ students to write their doctoral dissertation organised into individual \emph{theses} (corresponding to chapters), and to provide a breakdown on which of their publications are ``proof'' behind the thesis (chapter).
Originally, the package \textsc{theses-vs-publications} had been devised, but then we turned it to a more generic solution.

Commonly, the dissertation's \emph{``Introduction''} and \emph{``Summary''} chapters will provide the full table.
In addition, at the end of each individual thesis chapters will provide a table with the current thesis's row in the table \emph{highlighted}.

An example usage and association matrix is provided in \cref{example}.

\subsection{Example}\label{example}
The definitions (\cref{define}) should be done early in the document, but at least before the first table render (\cref{tablegen}) call.

\section{Commands}\label{commands}
\subsection{Registering entries}\label{define}

\command{amxrow}{\bslchar amxrow\lbchar <key>\rbchar\lbchar <text>\rbchar}{%
Registers the row entry named \texttt{<key>} with the given \texttt{<text>}.
The \emph{title} of the entry is printed in the first cell of the row, \textbf{in the order of} \texttt{\bslchar amxrow} calls.
}

\command{amxcol}{\bslchar amxcol\lbchar <key>\rbchar\lbchar <text>\rbchar}{%
Registers the column named \texttt{<key>} with the given \texttt{<text>}.
The contents of \emph{body} is printed as the column headings of the table, \textbf{in the order of} \texttt{\bslchar amxcol} calls.
}

\command{amxassociate}{\bslchar amxassociate\lbchar <col-key>\rbchar\lbchar <row-key>\rbchar}{%
Registers the association between \texttt{<col-key>} and \texttt{<row-key>}.
The cells at the intersection of the row and the column will have a \textbullet{}, indicating the relevancy.
}

\subsection{Queries}\label{query}

\command{amxrows}{\bslchar amxrows}{%
    Returns the number of rows defined.
}

\command{amxcols}{\bslchar amxcols}{%
    Returns the number of columns defined.
}

\command{amxrowtext}{\bslchar amxrowtext\lbchar <key>\rbchar}{%
    Returns the registered \emph{text} for the \textbf{row} registered with \texttt{<key>}.
}

\command{amxcoltext}{\bslchar amxcoltext\lbchar <key>\rbchar}{%
        Returns the registered \emph{text} for the \textbf{column} registered with \texttt{<key>}.
}

\subsection{Table generator: \texttt{amxgenerate}}\label{tablegen}

\command{amxgenerate}{\bslchar amxgenerate[<row>]}{%
    Generates the full table incorporating the previously registered data.
    Internally, a \texttt{tabular} environment is created with the table's data generated by the package.
    It is the user's responsibility to wrap this into a floating \texttt{table}, if they so wish.
    
    If \texttt{[<row>]} is given a row's \emph{key}, the row for that key will be \textbf{highlighted}.
    Highlighting is done by typesetting the row's \emph{text} in \textbf{bold face}, and changing every \textbullet{} in the \emph{other} rows to \textopenbullet{}.
    
    \begin{figure}[H]
        \centering
        \amxgenerate[latex]
    \end{figure}

% Let's use an example of 2×2 matrix for the customisations.
\newcommand{\docExampleResetTableTwoByTwo}{%
    \amxReset%
    \amxrow{sample}{Sample}%
    \amxrow{simple}{Simple}%
    \amxcol{x}{x}%
    \amxcol{y}{y}%
    \amxassociate{x}{sample}%
    \amxassociate{y}{simple}%

        \docExampleResetTableTwoByTwo
        \input{#2}
        \amxgenerate[#1]
    \end{figure}%
}

\subsection{Customisation}\label{customise}
All aspects on how the individual elements in the table are rendered can be customised by setting \emph{renderer} control sequences.

\makeatletter
    \def\defaultTopCorner{\amx@Renderer@Default@TopCorner}
\makeatother
\command{amxsetTopCorner}{\bslchar amxsetTopCorner\lbchar <new-heading>\rbchar}{%
    Sets the rendered table's top left cell value (by default, ``\emph{\defaultTopCorner}'') to the given \texttt{<new-heading>} value.

    \immediate\openout\tempfile=settopcorner-example.aux
        \immediate\write\tempfile{\bslchar amxsetTopCorner{Correlations}}
    \immediate\closeout\tempfile
    \loadAndRenderResettingExample{settopcorner-example.aux}
}

\command{amxsetColumnHeading}{\bslchar amxsetColumnHeading\lbchar<render-command>\rbchar}{%
    Sets the rendered table's top row's cells to be rendered via passing the column heading's text (see \cref{query}) to the given \texttt{<render-command>}.
    This command must be a command that takes \textbf{1} argument, defined by the user earlier.

    \immediate\openout\tempfile=setcolheading-example.aux
        \immediate\write\tempfile{\bslchar newcommand{\bslchar ttColHead}[1]{\bslchar texttt{\hschar1}}}
        \immediate\write\tempfile{\bslchar amxsetColumnHeading{\bslchar ttColHead}}
    \immediate\closeout\tempfile
    \loadAndRenderResettingExample{setcolheading-example.aux}
}

\command{amxsetRowFormat}{\bslchar amxsetRowFormat(Highlighted)\lbchar<render-command>\rbchar}{%
    Sets the rendered table's left cells' to be rendered via passing the row's index and text (see \cref{query}) to the given \texttt{<render-command>}.
    This command must be a command that takes \textbf{2} arguments, defined by the user earlier.
    The \texttt{Highlighted} version sets the renderer for the highlighted row, if highlighted rendering (see \cref{tablegen}) is done.

    \immediate\openout\tempfile=setrowformat-example.aux
        \immediate\write\tempfile{\bslchar newcommand{\bslchar parenRow}[2]{(\hschar1) \bslchar emph{\hschar2}}}
        \immediate\write\tempfile{\bslchar newcommand{\bslchar parenRowBl}[2]{!\hschar1! \bslchar texttt{\hschar2}}}
        \immediate\write\tempfile{\bslchar amxsetRowFormat{\bslchar parenRow}}
        \immediate\write\tempfile{\bslchar amxsetRowFormatHighlighted{\bslchar parenRowBl}}
    \immediate\closeout\tempfile
    \loadAndRenderResettingExample[simple]{setrowformat-example.aux}
}

\clearpage
\makeatletter
    \def\defaultIndicator{\amx@Renderer@Default@Indicator}
\makeatother
\command{amxsetIndicator}{\bslchar amxsetIndicator\lbchar<indicator>\rbchar}{%
    Sets the indicators of association in the matrix in \emph{non-highlighting} mode to the result of the \texttt{<indicator>}.
    The default indicator is: \defaultIndicator{}.

    \immediate\openout\tempfile=setindicator-example.aux
        \immediate\write\tempfile{\bslchar amxsetIndicator{a}}
    \immediate\closeout\tempfile
    \loadAndRenderResettingExample{setindicator-example.aux}
}

\makeatletter
    \def\defaultIndicatorHC{\amx@Renderer@Default@Indicator@Highlighted@Current}
    \def\defaultIndicatorHO{\amx@Renderer@Default@Indicator@Highlighted@Other}
\makeatother
\command{amxsetIndicatorHighlighted}{\linebreak\bslchar amxsetIndicatorHighlighted\lbchar<hl-indicator>\rbchar\lbchar<ot-indicator>\rbchar}{%
    Sets the indicators of association in the matrix in \emph{highlighting} mode to the result of the \texttt{<hl-indicator>} for the \textbf{highlighted row} and \texttt{<ot-indicator>} for every other row.
    The default indicators are: \defaultIndicatorHC{} and \defaultIndicatorHO{}, respectively.

    \immediate\openout\tempfile=setindicator-hl-example.aux
        \immediate\write\tempfile{\bslchar amxsetIndicatorHighlighted{c}{o}}
    \immediate\closeout\tempfile
    \loadAndRenderResettingExample[simple]{setindicator-hl-example.aux}
}

\subsection{Multiple distinct tables: \texttt{amxReset}}

\command{amxReset}{\bslchar amxReset}{%
    Clears \textbf{all} internal data structures and customisations for the package, allowing the user to later typeset a different, independent matrix.
    The previously defined entries are lost, and in case the ``previous'' matrix is needed, it must be set up again with a sequence of definition commands (see \cref{define}).
    
    For example, putting the code in \cref{example} and the one below into the same source file will create the smaller matrix at the second invocation of \texttt{\bslchar amxgenerate}.
    
    \immediate\openout\tempfile=reset-example.aux
        \immediate\write\tempfile{\bslchar amxReset}
        \immediate\write\tempfile{\bslchar amxrow{sample}{Sample}}
        \immediate\write\tempfile{\bslchar amxcol{x}{x}}
        \immediate\write\tempfile{\bslchar amxassociate{x}{sample}}
        \immediate\write\tempfile{\detokenize{\amxgenerate}}
    \immediate\closeout\tempfile
    
    \amxDisable
    \input{reset-example.aux}
    \amxEnable
    
    \begin{figure}[H]
        \centering
        \inputminted{latex}{reset-example.aux}
        \amxgenerate
    \end{figure}
}

\section{Development}
The development of \textsf{association-matrix} is done on GitHub: \url{http://github.com/whisperity/association-matrix}.
Please report issues and submit patches here.

Note that this document acts as a \textbf{test file} to the package, not only a user-facing documentation.
Any new command or change should be supplemented with appropriate documentation, and the check of the rendered examples.
If there is a discrepancy or regression in the looks of \emph{this document} that is not explained by the changes, it should be investigated!
