Hi Luigi,

It is OK by changing

line 46 in m-pstricks.mkii:
   \loadpstrickscolors{colo-rgb}}
to
   \loadpstrickscolors{colo-rgb.mkii}}

as Herbert said.

In the recent beta's, the change was already done.

Best,
Akira

I have a script cpCTX2TL which installs the current beta and
then copies all relevant files into the current TL installation.

I am using on Win7 x 64bit with standalone Context from
http://standalone.contextgarden.net/setup/context-setup-win64.zip
<http://standalone.contextgarden.net/setup/context-setup-win64.zip>

in \tex\texmf-context\tex\context\base\m-pstricks.mkii line 46 looks as
following:
    \loadpstrickscolors{colo-rgb.mkii}}

The following example does not yield anything

\usemodule[pstricks]

 \startPSTRICKS

\pspicture(0mm,0mm)(30mm,30mm)

\psline(0,0)(3,3)

Is there anything I am doing wrong?

Probably not, but the ConTeXt Minimals are missing support for
PSTricks (there are a lot of tools missing, including many binaries).
If you know how to install it, probably the easiest option to get
PSTricks running on Windows would be W32TeX.

(I could actually make a rsync-able complete version of W32TeX with a
relative ease. It contains the latest version of all the tools,
including ConTeXt. Maybe I should do that as MikTeX no longer supports
ConTeXt, TeX Live has frozen ConTeXt and binaries, ConTeXt
Distribution lacks some tools, and W32TeX is actually one of the best
TeX collections for Windows around; its only drawback is the lack of
an installer and updater – comparable to what MikTeX offers.)

Would you perhaps also have the instructions how to just add PST
to standalone ConTeXt, similar to TikZ is used in standalone ConTeXt. I
want to work with clean ConTeXt without all the overhead of MikTeX or any
other Windows version of TeX. In Standalone ConTeXt I work perfectly easy
with drawings in metapost, TikZ, and graphs with Gnuplot and R. I would
like to add PST to it, but was up to now unsuccessful.

Many Thanks

In the case of
mtx-context     | current version: 2014.12.11 12:02
The following is OK.

%
% context test.tex
%
\usemodule[pstricks]
\starttext
\startmidaligned
\startPSTRICKS
\pspicture(0mm,0mm)(30mm,30mm)
\psline(0,0)(3,3)
\endpspicture
\stopPSTRICKS
\stopmidaligned
\stoptext

Of course there are examples that don't match ConTeXt.

Best,
Akira

First of all try to figure out if you could use MetaPost or TikZ
instead. Either of them is a lot more "pdf-friendly".

Unless you still work with MkII and go via dvi->ps->pdf, you need to
compile the PSTricks graphic separately into DVI, then PS, then PDF,
and include the final graphic into the document. While ConTeXt macros
can do that for you, it's still very ugly. Unless you have a very very
very strong reason to use PSTricks, you would be better off with other
solutions.

In any case PSTricks isn't supported in the standalone distribution,
so you need to use TeX Live.


This is (probably) the proper syntax to get it running:

\usemodule[pstricks]
\starttext
\startPSTRICKS
\psline(0,0)(3,3)
\stopPSTRICKS
\stoptext

But for MkII you need to enable unrestricted write18, else you end up with

runsystem(texexec test-texapp.tex --once --batch)...disabled (restricted).
runsystem(dvips test-texapp)...disabled (restricted).
runsystem(ps2pdf test-texapp.ps test-texapp.pdf)...disabled (restricted).

(and maybe then it won't work anyway) and for MkIV it currently fails
to work as well:

(/usr/local/texlive/2014/texmf-dist/tex/generic/pst-tools/pst-tools.tex
`PST-tools' v0.05, 2014/05/12 (hv))  v1.63, 2014/06/24 (tvz,hv))
pstricks        : loading colors from colo-rgb
! I can't find file `colo-rgb'.
\loadpstrickscolors ...g colors from #1}\input #1
                                                  \relax \popmacro \dodefine...
l.47 ...s}{using indirect method; enable write18}}

(Press Enter to retry, or Control-D to exit)

Ah. I was running ConTeXt from TL 2014, but I was looking at the
sources from the latest distribution where the problem has already
been fixed. That confused me.

Anyway, the version in TeX Live now runs, but creates wrong results
(it prints out "(0,0)(3,3)" instead of drawing the line for example).

(And I'm not too eager to add support for PSTricks to the
distribution. It's a "can of worms" with zillion of other utilities
that we don't ship. And close-to-zero users.)

The problem is that this is not the only problem ;)

Or at least that didn't solve all the problems for me.

First of all I had to use Kakuto-san's example, adding something like

\pspicture(0mm,0mm)(30mm,30mm)
...
\endpspicture

in front and at the back (which is extremely ugly to see in ConTeXt).

So the complete minimal example was:

\usemodule[pstricks]
\starttext
\startPSTRICKS
\pspicture(0mm,0mm)(30mm,30mm)
\psline(0,0)(3,3)
\endpspicture
\stopPSTRICKS
\stoptext

However that still doesn't work with TeX Live 2014 even after fixing
the issue with mkii in the filename:

! Missing } inserted.
<inserted text>
                }
<to be read again>
                   \endgroup
\endpspicture ...]\fi \fi \pst@killglue \endgroup
                                                  \egroup \ifdim \wd \pst@hb...
l.12 \endpspicture

According to Kakuto-san it works with the latest ConTeXt, but I need a
bit of tweaking to try it out and even if it does users would need to
install (at least part of) W32TeX, wait for TLContrib to release a
newer version of ConteXt or tweak themselves in order to try it out.

I see,

\tikzpicture
..
\endtikzpicture

looks nicer ;-)

Well, that also, but in that case it would be \starttikzpicture ...
\stoptikzpicture. The pairs \tikzpicture ... \endtikzpicture and
\pspicture ... \endpspicture are plain TeX commands.

I would expect from ConTeXt to support

\startpspicture
...
\stoppspicture

out of the box (if it supported PST properly).

This is a minor issue that can be easily fixed by a few lines of wrapper 
code in m-pstricks.

pstricks relies on other parts of the tex ecosystem (a tex.pro file IIRC, 
and some binaries) that are not shipped with ConTeXt standalone. It will 
be great if MKIV supports pstricks out of the box. There are some very 
nice pstricks packages that are hard (and time consuming) to replicate.

No, but

\startMPcode
draw origin--(1,1) scaled 30mm ;
\stopMPcode

DOES look nicer ;-)

I have downloaded
cont-mpd.zip  cont-ppc.zip  cont-tmf.zip
and unzipped them into
texmf-dist of my 2014 TL (and rebuilt the formats and ls-R).
I have tried mtxrun --script update but it fails with
resolvers       | tds | no 'texmf-linux-64' under tree
'/opt/luatex/texlive/2014/tex'
(with a missed newline in my linux box)

The example works if one copies colo-rgb.mkii as colo-rgb.tex in the same
folder of the example
so I guess that we need to find a suitable location for colo-rgb.tex in the
tds
(I dont know if it's safe to add colo-rgb.tex to the base folder of
context, but I suspect it is not)

Metapost: point along path and metaobj

[Aditya Mahajan]

Hi,

  Something goes wrong while using metaobj and point something along 
somepath. I do not know if point ... along... is a mp core command or 
something introduced by metafun. Is this metafun's fault, metaobj's 
fault or simply a metapost issue (and thus I should ask on the 
metapost list).

\setupcolors
   [state=start]

\startMPinclusions
   input metaobj;
\stopMPinclusions
% Everything works fine if I comment metaobj.


\starttext
\startMPpage
   path p ; p := (0,0)--(1cm,0) ;
   draw p
     withpen pencircle scaled 2bp
     withcolor 0.8white;

   draw (point .25 along p)--(point .75 along p)
     withpen pencircle scaled 2bp
     withcolor red ;
\stopMPpage
\stoptext

gives

! Missing argument to arctime.
<to be read again>
                    of
along->(arctime((EXPR0)*(arclength(EXPR1)))of
                                              (EXPR1))of(EXPR1)
<to be read again>
                    )
l.295 draw (point .25 along p)
                               --(point .75 along p)

It is Metaobj's fault, it redefines (and therefore blocks access to)
the primitive command arctime. So I guess you should complain to
Denis Roegel (at the very least he should save the primitive arctime
under a different name). A workaround (I think) is this:

   input metaobj;
   primarydef pct along pat =
     arctime (pct,pat) of pat
   enddef ;

PsTRICKS in Context

[batela]

To all,

I am the author of a physics booklet written in LATEX+PsTRICKS.
Now,  my I intend  is to make one improved version in Context, but I 
have many
schems with  PSTRICKS commands. Did you know  a easy way  to make the 
migration?

Thanks a lot

Jorge

there is a module, m-pstric.tex


\usemodule[pstrick]

\startPSTRICKS
  \pspicture(0,0)(10,10)
    \dorecurse{10}{\psline(0,0)(\recurselevel,10)}
    \dorecurse{10}{\psline(0,0)(10,\recurselevel)}
  \endpspicture
\stopPSTRICKS

an option is to put the graphics in separate files and/or use checksum trickery as used in m-r (not yet done)

Re: PsTRICKS in Context

[batela]

Thanks.

But, in this LATEX_to_Context migration, I need to convert at hand 
several latex commands. For example:

\begin{itemize} to \startitemize

\end{itemize} to \stopitemize


\begin{table}_to_\starttable

and so on.

this is a very hard task.

Perhaps I need to make: perl -ps 's/\begin{itemize}/\startitemize/g'  
*.tex
