% \section{Introduction}% \iffalse TODO: SEC:Intoduction \fi
%
% This package uses TikZ to typeset Karnaugh maps in an easy way.
% Though the map size is restricted to four variables (as for \fileversion),
% it is easier and customizable compared to \textsf{karnaugh.tex}.
%
% \section{Installation}% \iffalse TODO: SEC:Installation \fi
%
% Install this package like any other \LaTeX~package.\\
%
% \noindent
% The end of this file contains the installation file (.ins) code in case
% the provided ins-file got lost.\\
%
% \noindent
% For style creation run |latex karnaughmap.ins|.
% For doc/manual creation run |latex karnaughmap.dtx| afterwards.
%
% \section{Dependencies}% \iffalse TODO: SEC:Dependencies \fi
%
% As of \textsf{karnaughmap}~\fileversion~this package depends on
% \begin{itemize}
% \item \textsf{tikz}
% \item \textsf{xkeyval}
% \item \textsf{ifthen}
% \item \textsf{xstring}
% \end{itemize}

%
% \subsection{Karnaugh Map Macros}% \iffalse TODO: SUBSEC:Karnaugh Map Macros \fi
%
% \DescribeMacro{\karnaughmap} |\karnaughmap|\oarg{key=value}\marg{entries}
%
% Use this macro inside of a |tikzpicture|-environment to typeset a Karnaugh map
% of a corresponding truth table.\\
%
% \paragraph{Example}
% Assume the truth table with inputs $a$ and $b$ and output $z$ is
% \begin{center}
% \begin{tabular}{ccc}
% $a$ & $b$ & $z$ \\\hline
% 0 & 0 & 0 \\
% 0 & 1 & 0 \\
% 1 & 0 & * \\
% 1 & 1 & 1
% \end{tabular}
% \end{center}
%
% \begin{minipage}[t]{0.45\textwidth}%
% Then, the corresponding Karnaugh map with default layout is:\\
% \begin{tikzpicture}[thick]
% \karnaughmap{00*1}
% \end{tikzpicture}\\
% \end{minipage}
% \hfill
% \begin{minipage}[t]{0.45\textwidth}%
% Which was typeset using:\\
% |\begin{tikzpicture}[thick] |\\
% | \karnaughmap{00*1} |\\
% |\end{tikzpicture} |
% \end{minipage}
%
% To produce empty maps, there are two possibilities.
% First is to use the key |defaultmap| described later and omit the mandatory input,
% the second is by providing a scalar mandatory argument that is equal the number of cells desired,
% i.e. 4,8, or 16.
%
% \begin{minipage}[t]{0.45\textwidth}%
% \begin{center}
% |\karnaughmap{4}|\\
% \begin{tikzpicture}[thick]
% \karnaughmap{4}
% \end{tikzpicture}\\
% \end{center}
% \end{minipage}
% \hfill
% \begin{minipage}[t]{0.45\textwidth}%
% \begin{center}
% |\karnaughmap[defaultmap=4]{}|\\
% \begin{tikzpicture}[thick]
% \karnaughmap[defaultmap=4]{}
% \end{tikzpicture}\\
% \end{center}
% \end{minipage}\\
%
% \medskip
%
% Note that it is also possible to provide the input string with blanks:
%
% \noindent
% |\begin{tikzpicture}[thick]|\\
% | \karnaughmap{1100 0101}|\\
% |\end{tikzpicture}|\\
%
% \begin{center}
% \begin{tikzpicture}[thick]
% \karnaughmap{1100 0101}
% \end{tikzpicture}\\
% \end{center}
%
% This is especially useful when larger maps are typeset as it increases
% readability of the \LaTeXe code.\\
%
%
% \DescribeMacro{\karnaughmapcolorfield} |\karnaughmapcolorfield|\oarg{key=value}\marg{map size}\marg{field string}\marg{color}
%
% Use this macro inside of a |tikzpicture|-environment to color a Karnaugh map of size |map size|.
% Use hexadecimal values to address a certain field of the map in the |field string|.\\
%
% \noindent
% |\begin{tikzpicture}[thick]|\\
% |\karnaughmapcolorfield{2}{01}{teal!50}%|\\
% |\karnaughmapcolorfield{2}{3}{violet!50}%|\\
% |\karnaughmap{4}|\\

% \karnaughmapcolorfield{2}{01}{teal!50}%
% \karnaughmapcolorfield{2}{3}{violet!50}%
% \karnaughmap{4}
% \end{tikzpicture}\\
% \end{center}%
%
% The keys for this macro allow for two different styles:
% \emph{filled} |fill| and \emph{outlined} |outline|.
% The default is filled.
% In addition, TikZ keys are forwarded to the |\draw| or |\fill| command,
% allowing a good adjustment of styles.\\

% \section{Field Allocation Reference}\iffalse TODO: SEC: Field Alloc Reference \fi
% This package provides maps with full control up to \emph{4} variables,
% which is equivalent to a map size of \emph{16} fields.\\
% For bigger maps, the package provides just basic typesetting,
% i.e. just the column and row encoding and the, possibly filled matrix.\\
% However, the biggest map supported yet has 256 fields.\\
%
% The reference can be read as follows:
% the first row contains the value of the rows,
% the columns are then likewise enumerated.
% By this procedure, you can check if everything went right (debugging)
% and got an easy reference.

% \paragraph{Switches}
% Simple switches are used to control basic layout options of the Karnaugh map.\\
%
% These boolean switches control if specific entries
% -- i.e. zeros, ones, and don't cares -- are printed or not (omitted).
% \begin{macrocode}
\define@boolkeys{karnaughmap}{omitzeros, omitones, omitdontcares}[true]
% \end{macrocode}
%
% These boolean switches control the layout of the Karnaugh map.
% The |omitbinaries| switch is used to control if binary encoding is typeset left and on top of the Karnaugh map.
% The |omitvariables| switch is used to control if the Karnaugh map is labeled with the variables.
% The |omitidx| switch controls the typesetting of decimal indices within the cells of the Karnaugh map.
% The |binaryidx| switch controls whether the indices are decimal or binary.
% The |omitnegated| switch controls whether the negated variable labels are typeset as well.
% \begin{macrocode}
\define@boolkeys{karnaughmap}{omitbinaries, omitvariables, omitidx, binaryidx, omitnegated}[true]
% \end{macrocode}
%
% These boolean switches control the behavior of the highlighting function.

%
% \paragraph{Customizations}
% In contrast to the boolean switches these keys are used to customize the Karnaugh map.\\
%
% This key controls the default size of the Karnaugh map.
% It is set to 16, i.e. a 4 variable map is typeset.
% \begin{macrocode}

%
% This key controls the Karnaugh map function label.
% The default is 'z'.
% \begin{macrocode}
\define@cmdkey{karnaughmap}{function}[z]{}
% \end{macrocode}
%
% This key controls the variables.
% Provide the variables as a string.
% Maybe more control over variables will be added in a later version.
% The default is 'abcd'
% \begin{macrocode}

% \end{macrocode}
%
% Define the standard "`Don't Care"' character.
% The default is '*'.
% \begin{macrocode}

% Define the color.
% For desired functionality both the draw and color have to be set.

\colorlet{karnaughmapColor}{#1}%
\colorlet{karnaughmapMapColor}{#1}}

% Default is the same as color.
% \begin{macrocode}
\define@key{karnaughmap}{draw}[karnaughmapColor]{\colorlet{karnaughmapMapColor}{#1}}
% \end{macrocode}
%
% Define the label color.
% By setting the color only, the draw remains unchanged.
