pstrics module again

pstrics module again

Dear sirs

The pstrics module don't work anymore. I tried to run this simple code but
I found a lot of errors.

\usemodule[pstric]
\starttext
\startPSTRICKS
\pspicture(0,0)(20,20)
\psline(0,0)(20,20)
\psline(1,1)(10,10)
\endpspicture
\stopPSTRICKS
\stoptext


This module is no longer supported?
There is still any hope of being able to use pstric and some of its
extensions (pst-spectra, for example)?

Thanks a lot

Sorry for my persistence about pstrics module.

Thanks a lot

Jorge

It appears that pstrick files are no longer part of the standalone 
distribution, but if you copy a bunch of files, then the above example 
does work.

This is what I did.

1. Compile the file. You get an error that some pstrick file is missing. 
Locate that file in the texlive directory and copy it to the current 
directory.

2. Repeat until you get an error that \ifx! is not a valid control 
sequence.

3. Run `grep ifx! *.tex` and change all the "\ifx!#1" to "\ifx !#1".

4. Then you get an error that colo-rgb is missing. Copy colo-rgb.mkii to 
the current directory as colo-rgb.tex.

5. Then you get a error message the some .pro file is missing. Find that 
file from the texlive directory and copy it to the current directory. 
Repeat until all errors are resolved.

Finally you'll get the correct output.

So it seems that if pstricks is added back to the minimals (so that errors 
in step 1 and 5 don't happen), then it should be straightforward to get it 
to work with context. (Just load the file with the correct catcode regime, 
so that ! is a other character, and the error in step 2-3 will not 
happen). THe error in step 3 is easy to fix by editing m-pstricks.

why does ConTeXt needs the space before the !  ??

ConTeXt has two catcode regimes: the "standard" catcode regime and the 
"unprotected" catcode regime.

In the "unprotected" catcode regime, !, _, and @ are also letters. This is 
done so that one can use csnames such as \c!width, \!!plusone, etc. 
(Similar to \makeatletter in LaTeX).

I haven't looked at the actual code, but I am guessing that at some place, 
the following code is being called:

\unprotect
\input pstricks
\protect

and therefore when ConTeXt sees \ifx!#1 it thinks that \ifx! is a csname. 
Adding a space after \ifx avoids that.

As I said in my previous message, this is easy to fix at ConTeXt end 
defining an appropriate catcode regime before inputing pstricks.

So, the pstricks package does not need to be changed, but the ConTeXt code 
that is calling the package needs to be adapted.

 radical solution

 Download and unpack the PSTRicks-TDS.tar to a directory
 cp ./PSTricks-TDS/tex/generic/*/*.tex .
 perl -pi.back -e 's/\ifx!#1/\ifx !#1/g;' *.tex
 rm -rf *.back
 cp /usr/local/texlive/2013/texmf-dist/tex/context/base/colo-rgb.mkii
./colo-rgb.tex
 run context

 change in m-pstric.* files ps2pdf to pstopdf

tanks a lot

I d'ont know how to fix the picture size.
No errors at all, but the figure size isn't correct.

Confirmed.

The proper interface is

\usemodule[pstricks]

\usePSTRICKSmodule[pst-add]
\usePSTRICKSmodule[pst-spectra]

When you run the above file, ConTeXt creates the following temp file:

\starttext
     \pushcatcodetable
     \setcatcodetable\texcatcodes
     \usemodule[pstric]
     \readfile{pst-add}{}{}
\readfile{pst-spectra}{}{}
     \popcatcodetable
     \startTEXpage
         \hbox\bgroup
             \ignorespaces
\pspicture(0,-2.5)(\textwidth,1.6)
\psspectrum[element=H, emission](0,0)(\textwidth,1.5)
\rput(2,1){Hydrogen spetrum}
\endpspicture
             \removeunwantedspaces
         \egroup
         \obeydepth % temp hack as we need to figure this out
     \stopTEXpage
\stoptext

runs ""mtxrun --script texexec %s --once --dvips <filename>"
and then runs "ps2pdf inputname outputname"

but that generates the file with the wrong size. dvips gives the following 
error message:

' TeX output 2013.11.25:1841' -> test-pstricks-0001.ps
Page 1 may be too complex to print
dvips: no match for special paper size found; using default

(and that is the reason for the wrong paper size).

It has been years since I used dvips, so I don't remember how to correct 
that. Basically, the "bug" is with the following file:

\starttext
\startTEXpage
   What will happen now
\stopTEXpage
\stoptext

Process using "mtxrun --script test --dvips" and then "ps2pdf" and the 
resulting pdf file has the wrong bounding box.

The file processes correctly (but in landscape orientation) when using 
pstopdf, so it is just a bug of ps2pdf.

The header of the ps file is:

%!PS-Adobe-2.0
%%Creator: dvips(k) 5.993 Copyright 2013 Radical Eye Software

Why is dvips adding Orientation: Landscape in the header?

did you used "ps2pdf -dAutoRotatePages=/None <file> "  ??
