\section*{Introduction}

\href{http://www.jflap.org}{\JFLAP}\footnote{\httpURL{www.jflap.org}} is a
popular Java program for experimenting with finite state machines, Turing
machines and other concepts from Formal Languages and Automata Theory. Version
7 of \JFLAP\ can export JPG, PNG, GIF, BMP, or SVG images. \jtot\ is a
\href{http://groovy.codehaus.org}{Groovy}\footnote{\httpURL{groovy.codehaus.org}} script
that converts a \JFLAP\ jff file representing a finite automaton, pushdown
automaton, or Turing machine into a \LaTeX\ file depicting the automaton
graphically using \tkz.

\section*{Requirements}

To use \jtot\ you will need \href{http://www.java.com}{Java}
installed. Additionally, you may find it useful to have
\href{http://groovy.codehaus.org}{Groovy} installed as well. You will
need to download either {\tt jflap2tikz.jar} (if you only have Java
installed) or {\tt jflap2tikz.groovy} (if you also have groovy
installed).

\section*{Usage}

\jtot\ is invoked from the command line with:
\begin{quote}
\begin{verbatim}
java -jar jflap2tikz.jar -i example.jff
\end{verbatim}
\end{quote}
or:
\begin{quote}
\begin{verbatim}
groovy jflap2tikz.groovy -i example.jff
\end{verbatim}
\end{quote}
In the above cases the output will be written to the console. Use the -h option
to see the full usage information, which is also given in
Figure~\ref{fig:usage}.

\begin{verbatim}
usage: jflap2tikz [options]
Version 1.2
 -d,--accepting-distance <distance>   Distance, in pt, between the circles of an
                                      accepting state (default is 2)
 -g,--grid <size>                     Round positions so that they are on a
                                      grid. If a size is given it sets the
                                      spacing of the grid (default is 20.0)
 -h,--help                            Show usage information and quit
 -i,--input-file <filename>           Name of a JFLAP jff file representing a
                                      finite automaton, pushdown automaton, or
                                      Turing machine. If a file is not given
                                      standard input will be used.
 -k,--keep-names                      Use the state names from the JFLAP file.
                                      The default is to replace the state names
                                      with names of the form '$q_{id}$', where
                                      id is the unique state number. Note state
                                      names will not be sanitized and thus may
                                      contain invalid TeX.
 -l,--arrow-length <length>           Length of arrows in points (default is 9)
 -o,--output-file <filename>          Name of a file for writing output. If this
                                      file already exists it will be
                                      overwritten.
 -r,--rotate                          Rotate labels along edges
 -s,--scale <x>                       1 pixel in JFLAP = x points in LaTeX
                                      (default is 1.0)
 -w,--arrow-width <width>             Width of arrows in points (default is 6)

\section*{Examples}

The following figures show machines from the book
\href{http://www.jflap.org/jflapbook/}{JFLAP: An Interactive Formal
  Languages and Automata Package} being converted to \tkz\ using
\jtot. Note that \jtot\ currently ignores \JFLAP\ state
annotations. Furthermore, not all \JFLAP\ files will be converted
perfectly. You may have to adjust the scale and/or gridsize, or edit
the resulting \tkz\ code to achieve the effect you want. However,
\jtot\ should provide a good starting point.
