What is the thesis going to be about? (I just noticed that mptopdf
complains about missing bibtex files. :)

> PS: Do you have a BibTeX entry for your gnuplot module?

Do you suggest me to publish an article about the terminal in arXiv,
to get at least some citations by the time when I need to submit my
thesis? :P

But no, I don't have it. I could try to create one though, but I'm not
even sure what the webpage should be. Many scientific programs just
ask to cite their first article in some scientific journal if one uses
the software, but I neither have an article nor homepage apart from
that (still outdated) wiki page.

There is some additional documentation on
https://github.com/mojca/context-gnuplot/tree/master/texmf/doc/context/third/gnuplot
(possibly also in minimals, but I'm not sure when I last synced the
version), but even that is outdated now since they required from me to
strip down terminal options parsing code.

The topic is how long integrated random walks stay positiv. Not being
able to prove that formally for double-integrated(?) random walk, I am
doing some simulations.

It seems to work for me.

That is an idea. ;-)

I thought asking does not hurt. ;-) So I guess I will just reference
ConTeXt and gnuplot then.


Thanks,

Actually the configurable temp dir would be OK too.

  texexec document.tex --tempdir=./temporaries

Regarding cacheing, this would be nice but I don't know if it can be
done. I think you still need to run gnuplot in case the data has
changed.

This sounds fine (having a --debug-like option), but one more question
- what about caching existing results? (If all files are deleted, then
it's not possible to ask for --ifchanged, so gnuplot needs to be run
each time.)

That's not too practical.

A configurable directory would indeed be the perfect solution (also
for other temp files).

Which is not always desirable. If I have
plot 'data.dat'
and change data, then the graph won't be recompiled.

The ideal would be an option when processing the source file, to turn
off file deletion. Like

texexec document.tex --keep-temporaries

So by default the source directory would be kept clean, but when
"debugging" the intermediate files would be available.

Or perhaps some option passed to \startGNUPLOTscript (or
\useGNUPLOTgraphic) if that is possible?

 \startGNUPLOTscript[example][keeptemporaryfile=yes]

That might be better otherwise debugging a big document could result
it hundreds of files.

Another possibility would be to put the files in /tmp.

I don't use gnuplot, but it's the same problem with lilypond - lots  
of files cluttering my project directory.

It would be a good solution if we could write all those temp files to  
a configurable directory (that one can delete or not).
The problem is probably that our client app (gnuplot, lilypond) or at  
least ConTeXt's "has changed" testing depends on that files.
If you find a solution for gnuplot I'd like to copy it for lilypond.

No major difference. But it would (should, at least) be compatible
with all the three: LaTeX/plain/ConTeXt.

When I have developed the terminal with enormous Hans's and Taco's
help, I have asked him to implement some functionality to delete the
files with ctxtools --purge. He has implemented some functionality
(\registertempfile or something - need to check), but it deletes the
files automatically at the end of run, so one either needs to:
- delete the files
- leave the files
- no option to delete files with ctxtools
The problem with deleting the files immediately is that if you make a
trivial mistake in the gnuplot script, gnuplot won't create any
output, and it's rather difficult to spot the error in the long bunch
of ConTeXt messages. You just get no graphic, any you wonder why.

Do you have any suggestions about how to reduce the number of files in
some sensible way?

Yes it's fine, the square brackets are better.

I really like gnuplot and the gnuplot module. It is great to be able
to include the data inline with the document. And it would be nice to
see it part of the distribution. I am using a stock debian gnuplot, so
I don't know the implications of the context and TikZ terminals. Does
it mean I would not end up with so many  *-gnuplot-* files? :)
