% \section{Introduction}
%
% The \rubiktwocube\ package (part of the \textsc{rubik} `bundle') provides a
% collection of \LaTeX\ commands
% and macros for typesetting Rubik 2x2x2 cube configurations using the
% PGF/TikZ graphic languages.
% This package is a minor extension of the \textsc{rubikcube} package, and users are
% therefore assumed to be familiar with both the \textsc{rubikcube} and \textsc{rubikrotation}
% packages. For examples of use see the file \texttt{rubikexamples.pdf}.
%
%
% \subsection{Requirements}
%
% The \rubiktwocube\ package requires the TikZ package (since it makes
% use of the TikZ picture environment), and also the
% \textsc{rubikcube} package.
%
% For full functionality the complementary packages \textsc{rubikrotation} and
% \textsc{rubikpatterns} also need to be loaded.
% Note that the \textsc{rubikrotation} package requires Perl to be installed.
% See the `Installation' section in the \textsc{rubikcube} package documentation
% (\texttt{rubikcube.pdf}) for more details.
%

% version 1.3c of this license or any

%
%
% \section{Installation}
%
% The Rubik bundle consists of the four packages \textsc{rubikcube}, \textsc{rubikrotation},
% \textsc{rubikpatterns} and \textsc{rubiktwocube}.
%
% Here we describe only the installation of the \textsc{rubiktwocube} package,
% which consists of the following files:
%\begin{verbatim}
% rubiktwocube.ins
% rubiktwocube.dtx
% rubiktwocube.pdf --documentation of the rubiktwocube package
% rubiktwo-doc-figA.pdf
%\end{verbatim}
% Before installing the \textsc{rubiktwocube} package make sure the following packages
% are already installed (TikZ graphics system and the \textsc{rubikcube} package).
%
%
% \subsection{\texttt{rubiktwocube.sty}}
%
% The style option \texttt{rubiktwocube.sty} is generated by running (pdf)\LaTeX\ on
% the file \texttt{rubiktwocube.ins} as follows:
%\begin{verbatim}
% pdflatex rubiktwocube.ins
%\end{verbatim}
%
%
% \subsection{\texttt{rubiktwocube.pdf}}
%
% The documentation file (\texttt{rubiktwocube.pdf}) is then generated using the following
% steps\,\footnote{Several pdflatex runs are required, since the documentation includes
% an index as well as hyperef links (the package \texttt{hypdoc}
% is used). Prior to the first run it is
% a good idea to delete any relevant \texttt{.toc}, \texttt{.aux}, \texttt{.out} files.}:
%\begin{verbatim}
% pdflatex rubiktwocube.dtx
% pdflatex rubiktwocube.dtx
% makeindex -s gind.ist rubiktwocube
% makeindex -s gglo.ist -o rubiktwocube.gls rubiktwocube.glo
% pdflatex rubiktwocube.dtx
% pdflatex rubiktwocube.dtx
%\end{verbatim}
%
%
% \subsection{Placing the files}
%
% Place the files either in the local working directory, or where your system
% will find them. For a Linux system with a standard \TeX\ Directory Structure (TDS), then:
%
%\medskip
%{\noindent}*.sty $\rightarrow$
% \texttt{/usr/local/texlive/texmf-local/tex/latex/rubik/}
%{\newline}*.pdf $\rightarrow$ \texttt{/usr/local/texlive/texmf-local/doc/rubik/}
%
% \medskip
% {\noindent}Finally, (depending on your system) update the \TeX\ file database.
% For~example, on a Linux system one uses the \texttt{texhash} command.
%
%
% \subsection{Usage}
%
% Load the package by using the command \cmd{\usepackage\{rubiktwocube\}}.
% Note that the \rubiktwocube\ package requires the TikZ package, and so always load TikZ
% before \rubiktwocube\ as follows:
% \begin{quote}
%\begin{verbatim}
% \usepackage{tikz}
% \usepackage{rubikcube,rubikrotation,rubikpatterns,rubiktwocube}
%\end{verbatim}
% \end{quote}
%
%
%
% \subsection{\texttt{rubikexamples.pdf}}
%
% The Rubik bundle includes a `RubikExamples' file (\texttt{rubikexamples.pdf})
% as well as associated \texttt{.sh} (Linux) and \texttt{.bat} (Microsoft) batch
% files which can be used to facilitate processing the source file (\texttt{rubikexamples.tex}).
% See the `Installation' section in the \textsc{rubikcube} package documentation
% (\texttt{rubikcube.pdf}) for details regarding processing the examples source file.
%
%

%
% \section{Command conventions}
% \label{sec:conventions}
%
% The examples given in the file \texttt{rubikexamples.pdf} present a good overview of
% the commands and how to use them.
%
%
%
% \subsection[Keywords Two and Rubik]{The keywords Two and Rubik in commands}
%
% In order to try and keep commands intuitive\,\footnote{This is a tricky problem
% given the large number of commands, so any feedback or ideas on how to avoid ambiguity,
% including pruning or revising `bad' commands, is always welcome.}
% we adopt the convention that the word `Two' in a command reflects the fact that
% the command relates to a 2x2x2 cube (a `Two' cube). Similarly, commands which relate
% to a 3x3x3 cube (a `Rubik' cube) ---see the \textsc{rubikcube} package---
% use instead the word `Rubik'.
%
%
%
% It is assumed that users are familiar with the \textsc{rubikcube}
% and \textsc{rubikrotation} packages, since virtually all \rubiktwocube\
% commands mirror the Rubik (3x3x3) cube commands, such that the word `Rubik'
% is replaced by the word `Two' (exceptions are highlighted).
% For example, the commands for drawing a 2x2x2 cube and a 3x3x3 cube from a RU viewpoint
% are respectively \cmd{\DrawTwoCubeRU} and \cmd{\DrawRubikCubeRU}.
% The examples given in the file \texttt{rubikexamples.pdf} present a good overview of
% the commands and how to use them.
%
% For more detailed information see (a)~the `code' section (Section~\ref{sec:thecode}),
% or (b)~see the equivalent 3x3x3 commands in the \textsc{rubikcube} package.

% \label{sec:listofcolourcommands}

% The following list shows the \rubiktwocube\ colour commands paired
% (for convenience) with the equivalent 3x3x3 version from the
% \textsc{rubikcube} package. The \texttt{..} indicates that mandatory arguments are required.

%
% \section{The code}
% \label{sec:thecode}
%
% All the 2x2x2 code here is essentially a cut-down version of the
% 3x3x3 code (\textsc{rubikcube} package); i.e.,~we have mostly just
% removed the 3x3x3 code relating to middle columns and rows, exchanged the
% word `Rubik' for the word `Two' in command names, and refashioned some of the commands
% involved in writing the temporary file \texttt{rubikstate.dat}.
% We assume that users are familiar with the \textsc{rubikcube} and
% \textsc{rubikrotation} package documentation.
%
% In order to avoid much repetition, we describe here only the
% essential details for understanding the relatively minor changes made in order to
% transform the earlier 3x3x3 \textsc{rubikcube} package code into
% working 2x2x2 code. In the following, the various instances of the
% heading `\textsc{changes:}' imply that more extensive details will be found
% with the equivalent `Rubik' commands in the \textsc{rubikcube} or \textsc{rubikrotation}
% package documentation.
%
% Relatively few 2x2x2 square hieroglyphs are required; some needed
% reformulating from their 3x3x3 cousins, ie those associated
% with \texttt{L,\,Lp,\,R,\,Rp,\,U,\,Up,\,D,\,Dp}.
% The axis rotations and the rotations \texttt{F,\,Fp,\,B,\,Bp} simply required
% renaming; for~example, as a `TwoRotationHieroglyph' (\cmd{\trh..}) instead of
% the 3x3x3 `RubikRotationHieroglyph (\cmd{\rrh..}).
%
%
%
%
% \subsection{Package heading}
%
% The `RTC' in the following refers to the package name RubikTwoCube.
%
% \begin{macrocode}
%<*rubiktwocube>
\def\RTCfileversion{5.0}%
\def\RTCfiledate{2018/02/25}% February 25, 2018
\NeedsTeXFormat{LaTeX2e}
\ProvidesPackage{rubiktwocube}[\RTCfiledate\space (v\RTCfileversion)]
% \end{macrocode}
% The package requires TikZ (we use the pgfmathsetmacro command)
% ---so we load it if not already loaded.
% \begin{macrocode}
\@ifpackageloaded{tikz}{}{%
\typeout{---rubiktwocube requires the TikZ package.}%
\RequirePackage{tikz}}%
% \end{macrocode}
%
%
%
% {\noindent}The package requires \texttt{rubikcube.sty}. However \texttt{rubikcube.sty}
% is not automatically loaded (for the moment at least) since this makes it difficult
% to errorcheck new versions, so we just write a message.
% \begin{macrocode}
\@ifpackageloaded{rubikcube}{}{%
\typeout{---rubiktwocube requires the rubikcube package.}%
}%
\@ifpackageloaded{rubikrotation}{}{%
\typeout{---rubiktwocube requires the rubikrotation package.}%
}%
% \end{macrocode}
%
% \begin{macro}{\rubiktwocube}
% First we create a suitable logo
% \begin{macrocode}
\newcommand{\rubiktwocube}{\textsc{rubiktwocube}}%
% \end{macrocode}
% \end{macro}
%
%
%
%
% \subsection{Saving the Two-cube state}
% \label{sec:codesavingtwostate}
%
% Note that this package writes this state data to the same `output' file
% (\texttt{rubikstate.dat}) as used by the 3x3x3 \textsc{rubikrotation} package,
% since there is no need to change this (since the TwoCube corners will be processed in
% exactly the same way as for 3x3x3 cube corners).
%
% \begin{macro}{\@printTWOstate}
% This internal command writes the TwoCube state data to
% the `output' file \texttt{rubikstate.dat}, and is used by the \cmd{\TwoRotation} command
% (see also \textsc{rubikrotation} package documentation Sections on \textit{save rubikstate}
% and \textit{general overview} for further details).
% The file \texttt{rubikstate.dat} is read by the Perl script, and represents
% the state on which the \cmd{\TwoRotation} command acts.
%
% \textsc{changes}: Since this is a TwoCube all the non-corner facelets
% (ie those in middle rows \& columns) are filled with X (grey).
% We have also introduced a new line in the output file (\texttt{rubikstate.dat})
% namely \texttt{cubesize,two} which is used to inform the Perl program that we
% are dealing with a TwoCube.
% \begin{macrocode}
\newcommand{\@printTWOstate}{%
\@print{cubesize,two}%
\@print{\space \space up,\Ult,\Umt,\Urt,\Ulm,\Umm,\Urm,\Ulb,\Umb,\Urb}%
\@print{down,\Dlt,\Dmt,\Drt,\Dlm,\Dmm,\Drm,\Dlb,\Dmb,\Drb}%
\@print{left,\Llt,\Lmt,\Lrt,\Llm,\Lmm,\Lrm,\Llb,\Lmb,\Lrb}%
\@print{right,\Rlt,\Rmt,\Rrt,\Rlm,\Rmm,\Rrm,\Rlb,\Rmb,\Rrb}%
\@print{front,\Flt,\Fmt,\Frt,\Flm,\Fmm,\Frm,\Flb,\Fmb,\Frb}%
\@print{back,\Blt,\Bmt,\Brt,\Blm,\Bmm,\Brm,\Blb,\Bmb,\Brb}%
}
% \end{macrocode}
% \end{macro}
%
%
%
%
% \subsection{SaveTwoState command}
% \label{sec:codesavetwostate}
%
% \begin{macro}{\SaveTwoState}
% We create a TwoCube version of the existing \cmd{\SaveRubikState} command
% (\textsc{rubikrotation} package), simply for symmetry and convenience.
% This command is identical to the `Rubik' version, and will require
% the \textsc{rubikrotation} package to be loaded already (as does the following
% \cmd{\TwoRotation} command.
% \begin{macrocode}
\newcommand{\SaveTwoState}{\SaveRubikState}
% \end{macrocode}
% \end{macro}
%
%
%
%
% \subsection{TwoRotation command}
% \label{sec:codetworotation}
%
% Note that this command writes the data to the same file
% (\texttt{rubikstate.dat}) as that output by the equivalent 3x3x3
% \cmd{\RubikRotation} command, since there is no need to change this.
%
% Note that although the system works perfectly well even if we just continue to use the
% 3x3x3 \cmd{\RubikRotation} command, it was felt appropriate to implement a special
% TwoCube version of this command, since this allows the Perl script to be aware
% (via the \texttt{cubesize,two} line written to the \texttt{rubikstate.dat} file)
% which sort of cube it is dealing with, and hence allows the option for the program to
% adjust its action accordingly (for example, with regard to the randomisation procedure
% which is different for different cubes).
%
%
% \begin{macro}{\TwoRotation}
% The \cmd{\TwoRotation}\oarg{integer}\marg{comma separated sequence}
% command (a)~writes the current TwoCube state to the file \texttt{rubikstate.dat},
% (b)~writes the rotation sequence (either once or multiple times depending
% on the value of the optional integer argument), and then (c)~CALLs the
% Perl script \texttt{rubikrotation.pl}. It~also writes comments to the
% data file and also to the log file.
%
% The way we allow the user to (optionally) process the main argument multiple
% times is simply by writing the associated output command multiple
% times to the output data-file. Consequently, we require the \cmd{\TwoRotation}
% command to allow a square-bracket optional
% argument (a non-negative integer) to specify the number of such repeats.
%
% \textsc{2x2x2 changes}: (1)~We have replaced `Rubik' by `Two' in the command-name
% (2)~we use the command \cmd{\@printTWOstate} (see above) to write the current state data,
% (3)~the \texttt{RTC} in the fileversion and filedate names denotes `RubikTwoCube'.

% \subsection{Sidebars (Face)}
% \label{sec:sidebarsfacecode}
%
%
% Making sidebar macros for a TwoCube (converting the 3x3x3x versions
% to the 2x2x2 versions).
% {\newline} (1) change name $\rightarrow$ \verb!TWOside@barX!
% {\newline} (2) change the value \verb!(3 + \bs)! $\rightarrow$ \verb!(2 + \tbs)!
% (as only two squares on a side).
% {\newline} (3) change the Sidebar length parameter names by adding a \cmd{\t} prefix
% to distinguish the TwoCube parameters from those of the RubikCube. Thus we change
% the Rubik names (\cmd{\dx}, \cmd{\dy}, \cmd{\bw}, \cmd{\bl}, \cmd{\blh}, \cmd{\bs})
% to their equivalent Two names (\cmd{\tdx}, \cmd{\tdy}, \cmd{\tbw}, \cmd{\tbl},
% \cmd{\tblh}, \cmd{\tbs}).
%
% The coordinates of the bottom left corner of a TwoSidebar are (\cmd{\tdx}, \cmd{\tdy}).
% The other parameters are width (\cmd{\tbw}), length (\cmd{\tbl}),
% half length (\cmd{\tblh}), separation (\cmd{\tbs}).
%
% \begin{macro}{\TwoSidebarWidth}
% \begin{macro}{\TwoSidebarLength}
% \begin{macro}{\TwoSidebarSep}
% These commands set the width, length and separation of the Sidebars.
% Each takes a single scalar argument (no units).
% \newline\textsc{usage}: \cmd{\TwoSidebarWidth}\marg{0.5}

% \end{macrocode}
% We first set some default values. We have set the Sidebar
% width and separation to 2/3 those of the Rubik 3x3x3 values
% (so that when a 3x3x3 cube and a 2x2x2 cube
% are scaled to be the same size, then the Sidebar width and sep will be the same)
% These also seem to look good generally as well.
% Of course, users can adjust these as they wish anyway. Any new values will
% will of course act globally unless constrained (either by using curley brackets, or
% by writing them into a \TeX\ environment).

% This command \cmd{\NoSidebar}\marg{colour code} (defined in the \textsc{rubikcube} package)
% defines the colour for which sidebars should \textit{not} be drawn
% (particularly useful when drawing OLL configurations).
% This idea was suggested by Robert Ma\v{r}\'{\i}k (May 2017).
% {\newline}The principle is that we let the command \cmd{\NoSidebar} define a face colour,
% and then we use the \verb!\ifthenelse{\equal{#2}{\no@sidebar}}{}{...}! structure to either
% (a)~draw all sidebars as usual (if \cmd{\NoSidebar} is undefined),
% or (b)~draw all sidebars \textit{except} those having the \cmd{\NoSidebar} colour
% (if \cmd{\NoSidebar} colour = \verb!#2!).
% \newline\textsc{usage}: \verb!\NoSidebar{X}! \ If this command in \textit{not} inside
% an environment, then its action will continue until it is cancelled (undefined)
% as follows: \verb!\NoSidebar{}!.

% \subsection{Sidebars (Cube)}
% \label{sec:sidebarscubecode}
%
%
% In order to position sidebars adjacent to a TwoCube (ie in 3D)
% requires that we first make some new \cmd{\TWOside@bar..}
% commands which draw sidebars adjacent to the \textsc{back} face
% (we have already made the macros for the front
% face sidebars---see Section~\ref{sec:sidebarsfacecode}).
% Furthermore, these new macros need to be tailored to each of the
% four standard cube viewing directions RU, LU, RD, LD.
%
% Finally, the USER commands for drawing these sidebars need
% to accommodate (a)~some code for identifying each set of sidebars,
% and (b)~the viewing direction. So, for example, a USER command for
% drawing the sidebars associated with the cube edge formed
% by the \textsc{right} face and the \textsc{back} face
% (lets define this as the RB sidebar) as viewed from the RU direction,
% might be something like \cmd{\DrawTwoCubeSidebarRBRU}.
% Since this is not particularly user-friendly,
% we can improve on this slightly for the USER by
% (a)~defining the sidebar as \texttt{SidebarRB}, and
% (b)~appending the view direction in a curly bracket, say as \verb!{RU}!.
% This allows a more intuitive command structure for the USER,
% as follows: \verb!\DrawTwoCubeSidebarRB{RU}!.
% We then use the \cmd{\@join} command to append the string \verb!RU! to the string
% \verb!DrawTwoCubeSidebarRB! forming the (internal)
% command \cmd{\DrawTwoCubeSidebarRBRU}.
%
% In the following we will group the development according to to the view direction.
%

% (dx,dy) = bottom Left corner of single bar

% \subsection{\hspace{3mm}Hieroglyphs}
% \label{sec:codehieroglyphs}
%
% Not many changes to make (from rubikcube sty). In general we try to
% keep things fairly intuitive by changing Rubik $\rightarrow$ Two,
% and changing r $\rightarrow$ t.
% Note that since this package uses a lot of commands defined in the
% \texttt{rubikcube} package, eg the `join' utility and the rubikfont,
% consequently rubikcube sty needs to be loaded when running this package.
%
% We only need to make significant changes to the
% following hieroglyphs: L,R,U,D,Lp,Rp,Up,Dp.
%
% Unchanged are: axis rotations (eg Rc) and letter rotations (eg B),
% so these hieroglyphs just need newdefs making for them;
% eg trF $\leftarrow$ rrF, etc
%
% We need to rename some of the `square' furniture associated with the L,R,U,D etc face
% rotation hieroglyphs: for example, the D heiroglyph requires the following:
%{\newline} change rr $\rightarrow$ tr
%{\newline} change SquareD $\rightarrow$ SquaretD
%{\newline} change RubikD $\rightarrow$ TwoD
%{\newline} change textRubikD $\rightarrow$ textTwoD
%
% For a TWOcube we only need to make two lines in a square;
% ie we want to shift the top line down/sideways
% and shift the bottom line up/sideways by
% an amount which makes the final position = 1/3 of the square.
% Since the top and bottom lines (and also the left and right lines)
% are at 0.25 unit,
% then the extra distance = 0.25/3 = 0.0833;
% so for horiz lines we add/subtract @ty, and
% for vertical lines we add/subtract @tx.
%
% \begin{macro}{\@tx}
% \begin{macro}{\@ty}
%\begin{macrocode}
\pgfmathsetmacro{\@tx}{0.0833}
\pgfmathsetmacro{\@ty}{0.0833}
% \end{macrocode}
% \end{macro}

% \end{macrocode}
% \end{macro}
% \end{macro}
%
% We need to rename the basic `join' commands: ie change Rubik $\rightarrow$ Two, and

%
% \begin{macro}{\tr}
% \begin{macro}{\trh}
% \begin{macro}{\Two}

%
% Feb 2017 (RWDN): \ added the \cmd{\@tlen} length to the \cmd{\trhD} command to improve the
% spacing between two `arrow' square hieroglyphs; and also removed the terminal \cmd{\,}
% space. The same changes were made to all the `arrow' hieroglyphs.
