[pstricks] Using pstricks with Lua - is it possible?

[Hensh, Richard]

The problem has now been resolved. It turns out that MiKTeX ignores the configuration file `dvipdfmx.cfg'. 

1. Locate the file dvipdfmx.cfg in the texmf tree (e.g., C:\Program Files\MiKTeX 2.9\dvipdfm\config\dvipdfmx.cfg).

2. Open up a command prompt and execute the following:
 
    initexmf --edit-config-file dvipdfmx
  
  This will open a *local copy* of the file dvipdfmx.cfg in your default text editor (usually Notepad). If the local 
  copy is blank (and only if), then copy the contents from the file obtained in step 1 into the local copy and save. 

3. Install the modified versions of auto-pst-pdf.sty and pst-pdf.sty (see the fixes provided by Herbert Voss below).

Now you should be all set.

You can first try (see AutoPdf.tex below)

  xelatex autoPdf.tex
  
If that is successful try

  lualatex -enable-write18 AutoPdf.tex

Thanks to Herbert for all of his work on this.

Richard,
that is a real problem. I fixed both, pst-pdf and auto-pst-pdf
to work with files like:

\documentclass[10pt]{article}
\usepackage[dvips={},pspdf={}]{auto-pst-pdf}
\usepackage{pstricks-add}
\ifluatex
   \usepackage{unicode-math} %% loads fontspec
\else
   \usepackage{mathspec} %% loads fontspec
\fi
\setmathfont{XITS Math}
\begin{document}
Hello World

\def\xmin{-3}\def\xmax{3}
\def\ymin{-1}\def\ymax{10}
\begin{pspicture}(\xmin,\ymin)(\xmax,\ymax)
   \psaxes{<->}(0,0)(\xmin,\ymin)(\xmax,\ymax)
   \psclip{\psframe[linestyle=none](\xmin,\ymin)(\xmax,\ymax)}
     \psplot{\xmin}{\xmax}{x dup mul}
   \endpsclip
   \psdots(2,4)
   \uput{6pt}[0](2,4){$y = x^2$}
   \NormalCoor
\end{pspicture}

foo bar baz
\end{document}

The images are now created with xelatex and not latex.
the two files are here:
