PPCHTEX with PSTricks option

PPCHTEX with PSTricks option

[Helge Kruse]

The minimal example shows diagonal lines. Since the line output of 
pictex is limited, I would choose PSTricks as output driver for better 
quality. When I enable the pstricks option, these diagonal lines collide 
with the radical atoms. You can easily reproduce this by removing the % 
comment symbol.

How can we improve the postscript output. Any hints are appreciated.

Best regards,
Helge Kruse

indeed the mkiv reimplementation will not be backported to latex as it 
involved a combination of tex, lua and mp now and is integrated into the 
context kernel (we have math in the kernel so why not chemistry)

looks like a pstricks is not loadec completely

i cannot test it here as pstricks with ppchtex in mkii does not work 
that well because i need to support latex and using the context pstricks 
layer would then complicat ethe code (in mkii we use metapost instead 
anyway)

Indeed, the problem is that I tried to run the pstricks option
under pdflatex, which, of course, does not work!
As I (almost) never use LaTeX anymore (and certainly never dvips)
I had forgotten about this.

I guess that I have become far too accustomed to ConTeXt and,
in particular, mkiv.

As to the original post, it yields acceptable results. The new ppchtex
in mkiv core is an improvement and, as Hans confirms, will not be backported
to laTeX. This could be one of many good reasons to switch from LaTeX to
ConTeXt!

So PPCHTEX is frozen for LaTeX?

The pictex output is not convincing, so I hoped the PSTricks output 
would gave better result. In general it works, but the diagonal bonds 
are too long. I Hoped that this could be fixed.

Skimming the ppchtex.noc I found that metapost is one possible output 
"driver". I also found a documentation for metapost. But I don't see how 
I can make PPCHTEX work with metapost in LaTeX. I even don't know if 
metapost can be used in LaTeX as in ConTeXt.

Well I am curious and I would evaluate ConTeXt. I think that 
http://www.pragma-ade.com/ will be a good starting point to do that. 
Unfortunately I did not found "How to install ConTeXt". Can this be done 
by adding some packages in MiKTeX 2.8? Probably a silly question...

Helge

apart from bug fixes (and/or if someone submits more drawing definitions)

in fact, as we move on to luatex, the context version for pdftex / xetex 
is frozen as well

if we kno wwhere the problem sits it will of course be solved, however 
as i don't run latex i cannot see what goes wrong

in context mkii metapost support has been integrated for quite some time 
and in context mkiv it can be processed without noticing so there 
ppchtex uses even more metapost (which is why there are also some extras)

best start with installing the so called minimals (from 
contextgarden.net) which will give you an independent tree that does not 
interfere with anything else

btw, an easy test is:

\starttext

\startTEXpage

... some chemical ...

\stopTEXpage

\stoptext

which will give you a graphic that you then can include in a latex doc

I downloaded context-setup-mswin.zip, unzipped it to
   C:\Program Files(x86)\context
and ran "first-setup.bat --context=current". Now I have a Directory 
C:\Program\context. In the command prompt window I can see a lot of 
error messages like

   rsync: change_dir 
"/cygdrive/c/Program/texmf-context/scripts/context/lua" failed: No such 
file or directory (2)

   rsync: change_dir "/current/context/=current" (in minimals) failed: 
No such file or directory (2)

I also created a shortcut to a command prompt as described in the wiki. 
The command prompt opens but context fails to start:

   C:\Users\Helge\Documents\TeX\context>context
   'context' is not recognized as an internal or external command,
   operable program or batch file.

   C:\Users\Helge\Documents\TeX\context>

I found in the wiki:
   It is recommended that you choose a directory that does not have a
   space in its full path.

Ok. This recommendation should be a least a warning. But currently I 
have some new questions:
- How do I uninstall context?
- Which directories have been modified by the installer? Where do I have 
to repair my system?

Best regards,
Helge

Re: PPCHTEX with PSTricks option

Use a directory without a space.
Download the context-setup-mswin.zip file, unzip it into the
c:\context directory
Then run the first-setup.bat file.
After completion, press win+R and run this line from there:

C:\WINDOWS\System32\cmd.exe /k C:\context\tex\setuptex.bat

cd there your context file resides and run "context yourfile.tex"


Installer downloads files to the c:\context dir, so to uninstall
context, just delete the directory c:\context or in your case the
C:\Program Files(x86)\context and C:\Program\context dirs.
