There is now a new optional argument for the package: \Loption{ckeckengine}, which will
be used in later versions.
%--------------------------------------------------------------------------------------
\section{\texttt{pstricks-tex.tex}}
%--------------------------------------------------------------------------------------
This package collects all additional latex macros which must be definied
when running PSTricks with tex. They all moved from the base \texttt{pstricks.tex} into
this new file.
%--------------------------------------------------------------------------------------
\section{\texttt{pstricks.tex} (v. 2.98 -- 2019/05/16)}
%--------------------------------------------------------------------------------------
\subsection{Plotting multilines}
There is a new macro called \Lcs{psLine} (uppercase L!) which can have
only one or two pairs of coordinates. Remember that \Lcs{psline} can have more.
With \Lcs{psLine} and an defined arrow you'll get nothing for something
like \verb|\psLine{->}{1,1)(1,1)|, whereas \Lcs{psline} will output the arrowtip!
This behaviour of \Lcs{psLine} maybe helpful for animations where a speedvector
or a vector
is shown with its components and one do not really knows the coordinates.
\begin{BDef}
\Lcs{psLine}\OptArgs\OptArg{\Largr{$x_0,y_0$}}\Largr{$x_1,y_1$}\\
\Lcs{psLineSegments}\OptArgs\Largr{$x_0,y_0$}\Largr{$x_1,y_1$}\ldots\Largr{$x_{n-1},y_{n-1}$}\Largr{$x_n,y_n$}
\end{BDef}
If $P_0$ is missing for \Lcs{psLine} then $(0,0)$ as first point is assumed. \Lcs{psLineSegments} expects always
pairwise coordinates.
\begin{LTXexample}[width=7cm]
\psset{unit=2cm}
\begin{pspicture}(-1,-1)(1,1)
\degrees[12]
\pscircle{1}
\multido{\iA=0+1,\iB=3+1}{12}{%
\pnode(1;\iA){R}
\psLine[linecolor=gray,linestyle=dashed,
linewidth=0.4pt](R)
\psset{arrows=->,arrowscale=1.5,linewidth=1.5pt}
\rput(R){%
\psLine[linecolor=blue]({1;\iB}|0,0)
\psLine[linecolor=red](0,0|{1;\iB})
\psLine(1;\iB)}%
}
\end{pspicture}
\end{LTXexample}
\begin{LTXexample}[width=4cm]
\psset{unit=0.5cm}
\begin{pspicture}(6,6)
\psLineSegments[linecolor=blue]{->}(0,0)(0,1)(0,2)(0,3)(0,4)(1,4)%
(3,4)(4,4)(4,3)(4,1)(4,0)(2,0)
\end{pspicture}
\end{LTXexample}
\iffalse
There is a new experimental feature, which allows algebraic notation for
coordinates. It needs
\begin{verbatim}
\usepackage[useCalc]{pstricks}
\end{verbatim}
\begin{LTXexample}[width=5.5cm]
\begin{pspicture}[showgrid](5,5)
\psline[linecolor=blue]{->}%
(0,4/3*0.5)(0.6*sqrt{33}, sqrt{20+0.3})
\end{pspicture}
\end{LTXexample}
\fi
%$
\subsection{Relative coordinates -- experimental}
All objects which can have at least two pairs of coordinates
can use the »+«-operator to mark relative coordinates:
\begin{BDef}
\Lcs{psline}\OptArgs\OptArg{\Largr{$x_0,y_0$}}\Largr{$x_1,y_1$}+\Largr{$x_2,y_2$}\ldots\\
\end{BDef}
\begin{LTXexample}[width=5.5cm]
\begin{pspicture}[showgrid](5,5)
\psline[linecolor=blue]{->}%
(1,1)+(3,4)+(-2,-3)
\end{pspicture}
\end{LTXexample}
\begin{LTXexample}[width=5.5cm]
\begin{pspicture}[showgrid](-1,-2)(4,3)
\psaxes[labels=none]{->}(0,0)(-1,-2)(4,3)
\psbezier%
(!0.8 -95 PtoC 1 sub)+(8.5;85)+(5;-100)(2,1)%
+(1;-70)+(0.5;-110)(3,2)%
+(1;-80)+(0.5;95)(3.4,-0.8)
\end{pspicture}
\end{LTXexample}
\subsection{Error message}
Using PSTricks with \Lprog{pdflatex} will work only when using package
\LPack{auto-pst-pdf} and running the \TeX-file with
\begin{verbatim}
pdflatex -shell-escape <file>
\end{verbatim}
otherwise you'll get an error message which was misleading in the past:
\begin{verbatim}
[...]
! Undefined control sequence.
<recently read> \c@lor@to@ps
\end{verbatim}
This changes now to
\begin{verbatim}
[...]
! Undefined control sequence.
\c@lor@to@ps ->\PSTricks
_Not_Configured_For_This_Format
\end{verbatim}
\subsection{Optional argument \texttt{xetex}}
The output driver \Lprog{xdvipdfmx} for using \XeTeX\ or \XeLaTeX\ is not fully
compatible to \Lprog{dvips}. Especially some node operations will not work. If the
\LaTeX\ package detects a programm run with \XeLaTeX\ it automatically loads the file
\Lfile{pstricks-xetex.def} which defines some macros with a new name to keep the existing
ones. By now there is only
\Lcs{NCput}, which is the same as \Lcs{ncput}, but works with \XeLaTeX.
If someone wants to use these macros though he/she runs not \XeLaTeX\ then these macros are
available too by using the optional argument \Loption{xetex}:
\begin{verbatim}
\usepackage[xetex]{pstricks}
\end{verbatim}
