% \section{Introduction}
%
% This package provides the |\simplot| macro, which lets you use inline Simplot
% commands to generate graphics. Simplot is an interpreter program to generate
% vector graphics and is described in the
% \href{http://www.dekkerdocumenten.nl/simplot/program.shtml}{documentation}.
% \noindent The descriptions for the individual commands can be found in the
% \href{http://www.dekkerdocumenten.nl/simplot/index.shtml}{documentation of the
% simplot library}.
%
% \section{Usage}
%
% In your preamble, load the simplot style with |\usepackage{simplot}|.
% In your document you can then generate a graphic with the |\simplot| macro.
% For example, to generate a circle with a radius of 5 mm you can say:\\
% |\simplot{20 20 10 10 "" "" plarc 0 0 5 0 360 DOWN}|\\
% This generates a plotting field of 20x20 mm with the origin in the middle
% (10,10). The "" "" let the font and the altenate font at their defaults (Adobe Times
% and Symbol) and the arc is plotted with its center at the origin (0,0), a
% radius of 5 mm, starting at 0 degrees and continuing over 360 degrees.
%
% Since the macro compiles the Simplot commands on the fly, you must either, in
% your |texmf.cnf|, enable the |\write18| command, or you must compile you
% document with the |-shell-escape| option.
%
% \DescribeMacro{\simplot}
% The |\simplot|  macro has one argument, consisting of all Simplot commands generating a
% graphic, with one exception: normally a Simplot script starts with a call to
% |plinit|:
% \\[2ex]
% |plinit PDF filename pagewidth pageheight x-origin y-origin font alt font|
% \\[2ex]
% Here, the first three elements: |plinit PDF filename| are left out. This is
% because the filename of the \textsc{pdf} graphic is automatically genenrated.
% The first will be named |\jobname_1.pdf|, the second |\jobname_2.pdf|, and so
% on. So when your \TeX\ source is named |test.tex|, the graphics will be called
% |test_1.pdf|, |test_2.pdf|, and so on.
%
% \section{Examples}
% Here is a simple example, printing a text with a arrow under it:
%
% \begin{verbatim}
% 
% \documentclass{article}
% \usepackage[papersize={100mm,100mm},margin=5mm]{geometry}
% \usepackage{simplot}
% \begin{document}\newfont{\HUGE}{txb at 40pt}
% \center\HUGE
% \quad Entrance\\
% \simplot{
%   90 20 0 0 "" ""
%   plset PENDIA 2
%   plcolor .8 0 0
%   plu 75 18 pld 20 18
%   plarrow -15 -10 10 15 25 0 0 0 0 ""
% }
% \end{document}
%
% \end{verbatim}
%
% \noindent And this is how it looks:
% \newfont{\HUGE}{txb at 40pt}
% \begin{center}\HUGE
% \quad Entrance\\
% \simplot{
%   190 20 0 0 "" ""
%   plset PENDIA 2
%   plcolor .8 0 0
%   plu 75 18 pld 20 18
%   plarrow -15 -10 10 15 25 0 0 0 0 ""
% }
% \end{center}
% Here is another example:
% \begin{verbatim}
% 
% \documentclass{article}
% \usepackage[papersize={100mm,100mm},margin=5mm]{geometry}
% \usepackage{simplot}
% \begin{document}
% 
% \simplot{
%   90 20 0 0 "" ""
%   plset PENDIA 2
%   plu 75 18 pld 20 18
%   plarrow -15 -10 10 15 25 0 0 0 0 ""
% }
% \end{document}
%
% \end{verbatim}
%
% \noindent which produces just a picture:
%
% \simplot{
%  A4 50 50 "" ""
%  plrdxy 5 0 0 2 8 3 100 4 1 5 0
%  plaxfit 5 20 50 50 xtext ytext text
%  plpline 5 "" DOWN
%  plframe 5 3
% }

%    \begin{macrocode}
%    \end{macrocode}
%
% \section{Implementation}
%
% A counter, |\simplotpicno|, is needed to name the subsequent \textsc{pdf}
% graphics; it start with 1:
%    \begin{macrocode}
%<*package>
\newcount\simplotpicno\simplotpicno=1
%    \end{macrocode}
% 
% \begin{macro}{\simplot}
% The |\simplot| macro takes its argument, prefixes it with the missing 
% |plinit PDF filename| part that makes it a full Simplot script, and pipes the
% resulting string into the |simplot| program, which generates the \textsc{pdf}
% graphic.  That graphic, finally, is included with |\includegraphics|:
%    \begin{macrocode}
\RequirePackage{graphicx}
% \changes{v1.02}{2014/07/21}{
%  force space behind filename
% }
\newcommand{\simplot}[1]{\immediate\write18{%
  echo 'plinit PDF \jobname_\the\simplotpicno\space #1'|simplot}
  \includegraphics{\jobname_\the\simplotpicno}
  \global\advance\simplotpicno by 1
}
%    \end{macrocode}
% \end{macro}
%    \begin{macrocode}
%</package>
%    \end{macrocode}
