+Vaucanson-G : A LaTeX package for drawing automata and graphs
+
+Vaucanson-G is based on PSTricks and PSTricks does not generate dvi instructions but instead
+directly generate postscript commands. As a result, the drawings composed by Vaucanson-G
+are not correctly visible under a dvi previewer. A very common outcome is an unscaled drawing and
+all the labels are written at the origin.
+
+Vaucanson-G is a package of macros that allow to draw automata and graphs within
+texts written using LaTeX.
+Nota Bene: The commands for graphs are still under construction
+and are not described yet neither below nor in the manual.
+
+The design of Vaucanson-G implements the following
+underlying philosophy: "simple" automata should be
+described with simple commands.
+The complexity of commands (or the number of things to be remembered
+to use them) should gradually grow with the complexity of the figure
+composed by these commands.
+
+The following example shows how a simple automaton can be drawn
+with commands, in which only the minimal information needed (position
+and label of states, shape and label of transitions) is made explicit.
+
+\begin{VCPicture}{(0,-2)(6,2)}
+% states
+\State[p]{(0,0)}{A} \State{(3,0)}{B} \State[r]{(6,0)}{C}
+% initial--final
+\Initial{A} \Final{C}
+% transitions
+\EdgeL{A}{B}{a} \ArcL{B}{C}{b} \ArcL{C}{B}{b}
+\LoopN{A}{a} \LoopS{C}{d}
+%
+\end{VCPicture}
+
+This is achieved by the implicit definition of a large number of
+parameters that control the geometry of the figure: size of states,
+width of lines,...
+The way these parameters can be handled and modified yields what is
+the second feature of Vaucanson-G:
+-- the easy definition of styles for the elements of figures.
+-- the capability of handling the figures both in size and
+ appearance without modifying them.
+
+Vaucanson-G is a set of macros that uses commands of the PSTricks package,
+due to Timothy van Zandt and that appears in the current version
+of the LaTeX distribution.
+The knowledge of this beautiful macro package is not necessary to use
+the Vaucanson-G commands.

+\VCSG is a package that allows to draw automata within
+texts written using \LaTeX.
+It is a set of macros that uses commands of the beautiful \PSTricks package,
+due to Timothy van Zandt\footnote{%
+ The maintenance and evolution of \PSTricks has now been taken over by H.~Voss.}
+and which is part of
+the current \LaTeX\ distribution.
+\VCSG is the result of the experience gained in composing the several
+hundreds of
+figures in the book \emph{El\'ements de th\'eorie des automates}
+(\cite{Sak01}) and in several other papers and conferences slides
+of the authors.
+
+The design of \VCSG implements the following
+underlying philosophy:
+\begin{enumerate}
+ \item `simple' automata should be
+described with simple commands.
+
+ \item Every element of a figure can easily be given a style
+ (which differs from the implicit one).
+
+ \item The complexity of commands (or the number of things to be remembered
+to use them) should gradually grow with the complexity of the figure
+composed by these commands.
+
+ \item It should be possible to handle the figures both in size and
+ appearance without modifying them.
+\end{enumerate}
+
+The following example\footnote{%
+ somewhat artificial but which exhibits most of the simple commands.}
+shows how a simple automaton can be drawn
+with commands, in which only the minimal information needed (position
+and label of states, shape and label of transitions) is made explicit.

+
+The objectives of \VCSG are achieved by the implicit definition of a
+large number of
+parameters that control the geometry of the figure: size of states,
+width of lines, \etc
+and by the definition of commands that allow to
+handle and modify these parameters.
+
+The following pages gives a presentation of \VCSG that
+gradually introduces the commands from the basic ones that allow
+to draw already a good deal of automata to the more
+sophisticated ones that are used to modify the internal parameters.

+\section{Downloading and using the package}\label{sec.d}
+
+
+The \VCSG package is downloadable from the URL:
+
+\texttt{/igm.univ-mlv.fr/\URLtilde lombardy/Vaucanson-G/}
+
+\noindent
+and consists, beside the present manual, in seven files:
+the wrapper \texttt{vaucanson-g.sty},
+the main macro file \texttt{VauCanSon-G.tex},
+and five other ancillary files\footnote{%
+ {\it Cf.} Section~\ref{sec.mod} for an explanation on the role of
+ these files.}
+for options, patches and colors:
+\texttt{VCPref-default.tex},
+\texttt{VCPref-slides.tex},
+\texttt{VCPref-beamer.tex},
+\texttt{VCPref-mystyle.tex},
+\texttt{VCColor-names.def}
+\index{VCPref-default}%
+\index{VCPref-slides}%
+\index{VCPref-beamer}%
+\index{VCPref-mystyle}%
+\index{VCColor-names.def}%
+that should all be stored in the user's \texttt{texinputs} directory.
+
+A \LaTeX\ file that will use \VCSG macros should contain the call to
+the wrapper in the preamble:
+
+\verb+\usepackage{vaucanson-g}+
+
+The \VCSG commands are to be used in a \LaTeX\ file and not in a plain \TeX\
+file for it uses the macro \verb+\newcommand+ that does not exist in \TeX.
+
+\VCSG is based on the \PSTricks package.
+The knowledge of this macro package,
+described in \cite{Girou94}, \cite[Ch.~4]{GRM97},
+\cite{GRMRV07}, \cite{Voss07},
+is not necessary to use the \VCSG commands.\footnote{%
+ It probably helps in understanding how they are built, and is
+ useful if one wants to make figures that consists of automata but
+ also contains other graphical elements
+ ({\it cf.} Section~\ref{sec.pla}).}
+On the contrary, \VCSG has somehow be written to save on it.
+In particular, the \VCSG commands follow the simple (and rigid)
+syntax of \LaTeX\ commands concerning the way the arguments are
+specified, and not the much more flexible syntax of \PSTricks itself.
+
+
+But the call to \PSTricks commands has the consequence that \VCSG
+commands generate pieces of \texttt{Postscript} files which in turn
+has two main outcomes\footnote{%
+ which a user should have in mind before sending complaint and
+ request.}:
+ \begin{itemize}

+\section{Basic commands}\label{sec.b}
+
+An automaton is a \emph{labelled directed graph} where some of the vertices,
+called \emph{states}, are distinguished to be \emph{initial} or
+\emph{final} states.
+The basic commands allow then \emph{to define} and \emph{to draw}
+states, to give them the quality of being initial or final and to give
+them \emph{labels} as well.
+They allow to draw \emph{transitions}
+between states (that have been defined before);
+there are 3 kinds of transitions: \emph{(straight) edges}, \emph{arcs} and
+\emph{loops}.
+
+These commands have to be put in an environment that defines \emph{a
+picture}.
+All graphical parameters of these elements (size, line width, \etc )
+are kept implicit when using these basic commands.
+

+Its lower left (resp. upper right) corner has
+coordinates~($x_{0}$, $y_{0}$) (resp.~($x_{1}$, $y_{1}$)).
+\end{minipage}%
+
+\medskip
+
+The~$x_{i}$ and~$y_{i}$ are either \emph{length} or \emph{numbers} in
+which case they represent the corresponding length in centimeter (which
+is the implicit length unit used in \VCSG).
+The length of the box is thus~$x_{1}-x_{0}$, its
+height~$y_{1}-y_{0}$, its \emph{baseline point} stands at the middle
+of the height.
+As usual in \TeX, a picture may well ``contain'' an element that
+actually lays outside of the box.
+
+Note that the environment has only \emph{one} argument consisting of \emph{two}
+point coordinates enclosed in adjacent parentheses.
+%%%%%%%%%%%%%%%%%%%%%%
+\subsection{The \texttt{State} commands}\label{subsec.sta}
+\index{State}
+
+States are represented by circles, inside which an information (the
+\emph{Label}) can be written.
+Every state is given a \emph{Name} which is used then internally in the figure to describe the
+transitions that start from it or end at it.

+\noi
+There is no reason indeed for an author to ``program'' the drawing of
+an automaton at the size it will appear on his, or her,
+paper.
+On the contrary, he, or she, is likely to sketch the figure on a
+ruled paper at a larger scale, giving the points to be defined integer
+coordinates.
+And then she, or he, will try to put the figure within the text at a
+reasonable size and thus would like to scale it.
+
+The parameter \verb+\VCScale+ contains this global scaling factor and is
+initialized to the value \verb+0.6+ , which corresponds to the
+command \verb+\MediumPicture+.
+Three other commands:
+\verb+\TinyPicture+ ,
+\verb+\SmallPicture+ and

+commands \verb+\SmallState+, \verb+\MediumState+ and
+\verb+\LargeState+, that call for states of diameter
+\verb+0.6cm+, \verb+0.9cm+ and \verb+1.2cm+ respectively.
+The implicit size, \ie the one that states have if no explicit command
+is given, is \verb+\MediumState+.
+The ``small'' states are not likely to receive labels, unless their
+size are changed by other commands.

+%Independently of the preset size --- in this instance, of the \emph{height} ---
+One can draw states which will be called \emph{variable states} and whose
+\emph{width} is variable and \emph{fits the width of the
+label}.\footnote{%
+ This makes sense for long labels and it may be the case then that
+ the label is not a mathematical variable or expression any more
+ but simple text.
+ In order to write labels in \TeX\ LR mode, the easiest way is to
+ write it as the parameter of a $\backslash$\texttt{text} command,
+ provided the \texttt{amsmath} package has been called in the

+Note that the current version of \VCSG uses a trick to make these
+states with adaptable width.
+They look like Egyptian cartouches but they are indeed
+\emph{rectangles} which can be observed when transitions reach these
+states in an oblique way.
+
+Arcs between variable states of different width will look asymmetric
+and often ungainly.
+Other loops than ``north'' and ``south'' loops should not be drawn
+around variable states. Moreover, in order to draw loops that have the same appearance as loops
+around standard states, one should use
+\verb+\LoopVarN+ or \verb+\LoopVarS+
+that have the same syntax as \verb+\LoopN+ or \verb+\LoopS+.
+\index{LoopVarN}\index{LoopVarS}
+Another possibility is to call the \verb+\VarLoopOn+ command to make
+all the subsequent loops suited to variable states.
+Switching back to `normal' loops is made by \verb+\VarLoopOff+.
+\index{VarLoopOn}
+\index{VarLoopOff}
+
+For the same reason, it is \emph{not possible} to make a variable
+state initial or final with diagonal arrows ($ne$, $nw$, $se$, $sw$).

+\section{Composing a picture}\label{sec.com}
+
+The commands described above allow to define most of the figures
+representing automata in any textbook or technical paper.
+Before turning to more sophisticated commands that are used
+for less than 5 percent of the elements and that appear in less than
+10 percent of the figures, let us turn to few commands that help in
+composing the figures.
+
+
+%%%%%%%%%%%%%%%%%%%%%%
+\subsection{Structuring the automaton: The \texttt{VCPut} command}\label{subsec.rpu}
+
+In many automata, a same pattern in states, and also in edges, is
+reproduced several times in the figure.
+The idea is not to try to ``program'' these regular patterns but to
+allow the use of the ``copy-and-paste'' operations in the source
+file as much as possible, with minimum corrections afterwards.
+This will be achieved easily with the help of the
+command~\verb+\VCPut+.\index{VCPut}

+Note that this command is taken directly from \PSTricks but uses \VCSG's syntax.
+%the special syntax of that command which is taken directly from
+%PSTricks: the first argument ($x$,$y$)
+%\emph{is not} put inside braces.
+%There should not be any space before, after, and inside the
+%parentheses.
+
+Of course the commands that are to be put as the second argument
+of~\verb+\VCPut+ are the defining states commands, with possibly
+other~\verb+\VCPut+ inside.
+The structuration of the figure \textit{via} the use of~\verb+\VCPut+
+commands does not only save typing.
+It makes also easier the tuning of the figure, and the reusability of
+its parts.
+
+In the example below, the two~\verb+\VCPut+ are used to place the
+two parts of the automaton.

+\section{Modifying and setting the parameters}\label{sec.mod}
+
+The reason why the commands in \VCSG are simple and concise is that
+all the parameters that control the geometry (size, angles,
+\ldots) and the drawing (line width, line style, line color, \ldots)
+of the states and transitions in an automaton are preset by \VCSG and
+can be kept implicit.
+But there are two instances where a user may want to modify these
+preset values.
+
+The first case is when one needs to tune a parameter in order to make
+the figure more readable, or nicer.
+Such a case has already been considered in
+sections~\ref{subsec.edg}, \ref{subsec.arc} and~\ref{subsec.loo},
+where the parameter \textsl{Pos}
+that controls the position of the label of a transition along the
+edge has been modified with an optional argument.
+The parameters that will be considered in this section are not
+optional parameters of already defined commands but parameters that
+are set with their own commands.
+
+The other case where a user will change the implicit parameters of
+a figure or, more likely, of a set of figures, is when he (or she)
+will be in the position to change completely the ``style'' of the
+drawing.
+For instance, a same set of figures may be used in a paper \emph{and} in a
+series of slides for the presentation of the paper.
+Of course, the figures have to be set at a larger scale, probably
+in colour, and possibly with different relative sizes of the elements.
+
+We begin with the description of the options for the latter case,
+which is by far simpler. We then explain the syntax convention taken
+to coin the names of the many commands that control the many
+parameters.
+Then comes the list of these parameters, for scaling first, then for
+states, for transitions, and finally for the fine tuning of
+some details of the drawing.

+\subsection{Style files}\label{sec.sty-fil}
+
+The package \VCSG is loaded with default values that are all set up
+in the file \verb+VCPref-default.tex+~.
+\index{VCPref-default}%
+\index{VCPref-slides}%
+\index{VCPref-beamer}%
+\index{VCPref-mystyle}%
+The package comes with two other styles, in particular one for
+drawing slides.
+The normal way of using the different style files is to call the
+wrapper \texttt{vaucanson-g} with an option:

+% \footnotetext{There exists also, for downward compatibility, a

+
+Although it is not the normal usage,
+it is also possible to change style in the course of the text by

+case, it is recommended to reset all parameters by calling
+\verb+VCPref-default.tex+.

+\noi
+% In order to be effective, the command \verb+\Set+\textsl{Param} has to be
+% called \emph{outside} a picture.
+The command \verb+\Set+\textsl{Param} can be
+called \emph{outside} a \verb+\VCPicture+ environment, in which case
+it will be effective in all subsequent figures, until a new setting
+of the same parameter.
+Its natural place, if it is considered as a modification of the style,
+is in the preamble, after the call to the package \VCSG.
+If the command \verb+\Set+\textsl{Param} is
+called \emph{inside} a \verb+\VCPicture+ environment, its effect will
+be restricted to that figure.
+
+Such parameters will be called \emph{adjustable parameters} in the
+sequel.
+
+Note that in the case where \verb+\+\textsl{Param} is a value
+(a \emph{length} or a \emph{scale}), the
+value of \textsl{Val} in \verb+\Chg+\textsl{Param}\verb+{+\textsl{Val}\verb+}+ is a
+\emph{coefficient} which is applied to the style value of \verb+\+\textsl{Param}
+defined with \verb+\Set+\textsl{Param}\verb+{+\textsl{Val}\verb+}+.
+Therefore, in this case, \verb+\Rst+\textsl{Param} is equivalent to
+\verb+\Chg+\textsl{Param}\verb+{1}+.
+
+The other parameters, as those that define the ``dimmed'' style,
+are called \emph{preset parameters}.
+%Belong to that class those parameters that can be ``adjusted'' by means
+%of an optionnal argument, \eg \verb+\EdgeLabelPosit+ which gives
+%the implicit position of the label on an edge.
+
+There is finally a class of parameters that fall in between the
+adjustable and the preset ones, those for which several values are
+``preset'' but that can be given other values.
+%For instance, the scale of the
+%picture is fixed by the parameter \verb+\VCScale+: it can given
+%the preset values \verb+\NormalScale+, \verb+\SmallScale+ or
+%\verb+\LargeScale+
+%by means of the command \verb+\NormalPicture+, \verb+\SmallPicture+
+%or \verb+\LargePicture+ respectively, or given any chosen value
+%\textsl{Val} by the command \verb+\FixVScale{+\textsl{Val}\verb+}+ .
+%
+These parameters will be called \emph{multivalued preset parameters}.

+parameters for drawing edges (the length of initial and final arrows or

+\textit{ArrowOnX} is the coefficient that is applied to the radius of the state
+to obtain the length of initial or final arrows. \textit{LoopOnX} and
+\textit{CLoopOnX}
+is the eccentricity of loops and closed loops respectively.
+
+Another parameter determines whether the dimension of states
+refer to the middle, the inner or the outer side of the boundary.

+\paragraph{Transition adjustable geometric parameters}
+~
+All these parameters are adjustable. That means there
+exist commands as \verb+\Set+\textsl{Parameter}, \verb+\Chg+\textsl{Parameter}
+and \verb+\Rst+\textsl{Parameter}.
+
+Arcs between states are characterized by some adjustable parameters:
+
+\begin{center}
+\begin{tabular}{c|c|c|c|}
+\textsl{X} & \textsl{XAngle} & \textsl{XCurvature} & \textsl{XOffset} \\
+\hline

+\hline
+\end{tabular}
+\end{center}
+\index{ArcAngle}\index{ArcCurvature}\index{ArcOffset}
+
+\medskip
+Except the curvature that depends on the size of states,
+parameters that define loop,
+the degree of opening and the offset, are adjustable parameters.
+
+\begin{center}
+\begin{tabular}{c|c|c|}
+\textsl{X} & \textsl{XAngle} (degrees) & \textsl{XOffset} \\
+\hline
+\textsl{Loop} & \texttt{30} & \texttt{0}pt\\

+Likewise, one can modify the style of arrows, that are defined by
+three adjustable parameters~:
+
+
+\begin{center}
+\begin{tabular}{c|c|}
+Parameter & Default value \\
+\hline
+\textsl{EdgeArrowStyle} & \texttt{->} \\
+\hline
+\textsl{EdgeArrowWidth} & \texttt{5}pt \\
+\hline
+\textsl{EdgeArrowLengthCoef} & \texttt{1.4} \\
+\hline
+\textsl{EdgeArrowInsetCoef} & \texttt{0.1} \\
+\hline
+\end{tabular}
+\VCDraw{%
+\begin{VCPicture}{(-4,-2)(4,2)}

+\EdgeR{B}{Bh}{\text{Inset}}
+\EdgeR{C}{Ch}{\text{Width}}
+\end{VCPicture}
+}
+\end{center}
+\index{EdgeArrowStyle}\index{EdgeArrowWidth}%
+\index{EdgeArrowLengthCoef}\index{EdgeArrowInsetCoef}
+
+The {\em length} and the {\em inset} of arrows are given by
+coefficients that are applied to the {\em width}.
+There exists some other (non adjustable) parameters to define arrows
+in special cases:
+\verb+\EdgeArrowRevStyle+ is equal to \texttt{<-}, to draw transition
+in reverse mode; for edges with double lines, the size of
+arrows is a little bit more large.
+It is defined by \verb+\EdgeDblArrowWidth+
+and \verb+\EdgeDblArrowLengthCoef+ that are respectively equal to
+\texttt{5.5}pt and \texttt{1.7}.
+
+\medskip
+\noi
+Zigzag edges are characterized by some adjustable parameters:
+
+\begin{center}
+\begin{tabular}{c|c|}
+Parameter & Default value \\
+\hline
+\textsl{ZZSize} & \texttt{0.9}cm \\
+\hline
+\textsl{ZZLineWidth} & \texttt{1.7} \\
+\hline
+\end{tabular}
+\end{center}
+\index{ZZSize}\index{ZZlineWidth}
+
+\textsl{ZZSize} is the apparent diameter of the zigzag and \textsl{ZZLineWidth}
+is a coefficient that is applied to \textsl{EdgeLineWidth} and gives
+the width of the line.
+
+\paragraph{Transition preset parameters}
+~
+The default position of labels on transitions depends on the type of transition.
+For instance, on edges, this position is given by the variable \verb+\EdgeLabelPosit+
+that is equal to $0.45$. The first column of the following array gives these values
+for every transition.
+
+\begin{center}
+\begin{tabular}{c|c|c|}
+\textsl{X} & \verb+\+\textsl{X}\texttt{LabelPosit} & \verb+\+\textsl{X}\texttt{LabelRevPosit} \\
+\hline
+\texttt{Edge} & \texttt{.45} & \texttt{.55}\\
+\hline
+\texttt{Arc} & \texttt{.4} & \texttt{.6}\\
+\hline
+\texttt{LArc} & \texttt{.4} & \texttt{.6}\\
+\hline
+\texttt{Loop} & \texttt{.25} & \texttt{.75}\\
+\hline
+\texttt{CLoop} & \texttt{.25} & \texttt{.75}\\
+\hline
+\texttt{Init} & \texttt{.1} & \texttt{.9}\\
+\hline
+\texttt{Final} & \texttt{.9} & \texttt{.1}\\
+\hline
+\end{tabular}
+\end{center}
+
+When the reverse mode is on, the position of label is given by
+variables that correspond to the second column, as \verb+\EdgeLabelRevPosit+ for instance.
+For the same type of transition, the sum of both variables
+that defined position for straight and reverse arrows should
+be equal to $1$ (if one wants to keep the same appearance when using
+the \verb+ReverseArrow+ command).
+
+These parameters can be modified with a \verb+\renewcommand+.
+

+\section{Using ``plain'' \PSTricks commands}
+\label{sec.pla}
+\VCSG is a set of macros based on \PSTricks. It is therefore
+fully compatible with \PSTricks instructions.
+Actually, the \verb+VCPicture+ environment is a specialization
+of the \verb+pspicture+ environment; more, every state in \VCSG
+is a \PSTricks node and every transition (loop, edge, arc)
+is a node connection.
+
+The following example shows how \VCSG commands can be mixed
+with plain \PSTricks commands. For further explanation on
+\PSTricks, we refer to~\cite{Girou94,GRM97,GRMRV07,Voss07}.

+\section{Version history}
+
+A first version of the package, which would be numbered 0.1, was
+called \emph{Vaucanson} and used by the authors in their papers
+between 2000 and 2003.
+But, at the same time, the authors were involved, in cooperation with
+the LRDE at EPITA, in the design of a \texttt{C++} platform for
+programming automata, for which it was decided that there would be no
+better name than Vaucanson as well.
+We thus turned the name of the package for drawing automata to \VCSG.
+% The name of every \textbf{file} of the library has been changed accordingly.
+% No name of \textbf{command} in the package has been changed.
+
+Version 0.2 was issued in May 2003 and made available on the web
+together with this user's manual first version.
+A series of bug corrections and slight improvements made us switch at
+some point to version 0.3.
+
+Just before sending the package to CTAN, we undertook a full review of
+the code and updated the manual accordingly.
+We call it version 0.4.
+It is the last release before a completely new version of the
+package, with many more options , which is currently under work.
