[NTG-context] How can I properly credit ConTeXt
Hello there.
This was meant to be a mail to say thanks to the ConTeXt/LuaTeX teams
for the wonderful work they did and are doing. I'm pretty new to ConTeXt
but I'm really impressed. It happens that I'm typesetting a journal that
will hit the printer soon. Now, the question sounds: how can I credit
ConTeXt/LuaTeX properly? (no, it won't generate any profit so I can't
really donate some bucks; as a matter of fact I'm volunteering this)
I was thinking about something like:
\vfill
\startalignment[center]
Typeset with \ConTeXt\ and \luaTeX\
\goto{\hyphenatedurl{http://wiki.contextgarden.net}}
[url(http://wiki.contextgarden.net)]
\blank[big]
Fonts used: Linux Libertine
\goto{\hyphenatedurl{http://www.linuxlibertine.org}}
[url(http://www.linuxlibertine.org)]
\stopalignment
Is it OK?
Best wishes

Marco

It should be fine, but why not set it up as a standard colophon?

Re: [NTG-context] Exist any table environment flag?
Thanx Wolfgang!
It works fine now ... it is great...
I don't found (by google) any more information about \ifintable or
\iftrialtypesetting flags.
Can I find anywhere more information about them?
I have now still one similar question. Is there any flag which indicate
whether to use \expanded macro? I want to checked using the \expanded{}
macro as input parameter of my own macros.
for example:
\def\tbline{\expanded{\bTR\bTD \myfirstcolumn \eTD\eTR}}
\mytablerow{\tbline}
\def\mytablerow#1{ ... I want testing here, if #1 contain \expanded{}

Hello ConTeXist,
I want my macro to act differently inside \bTABLE ... \eTABLE environment and
otherwise outside of that environment.
Is there any sign (flag) which can determine whether my macro run inside or
outside the \bTABLE .. \eTABLE environment?
Or do I have two similar versions of my macros (one for the table environment
and the other for normal environment)
\ifintable but this is not available for tabulate, another alternative is to
use \iftrialtypesetting
Explanation: To my macro work, I must have already expanded values inside table
environment...
In this case you have to expand the whole table before it’s processed, e.g.
\bTABLE
\bTR
\expanded{\bTD ... \eTD}
\eTR
\eTABLE

[NTG-context] Convert eps to pdf
ConTeXt mkiv will take an encapsulated postscript (eps) file through \externalfigure [myfigure.eps] and creates a (compressed) pdf version as m_k_i_v_myfigure.pdf that conserves the vectorial components of the eps file. Other standard conversion tools, notably those based on ghostscript, generally create a bitmap image with pretty horrible results. The vectorial conversion must be fully trivial, but I am ignorant of the tools available for this manipulation (other than ConTeXt!), as well as the inverse (pdf-eps) conversion. Perhaps I am simply missing some simple (ghostscript, pstoedit, ...) option. I am posting this question to the ConTeXt mailing list as I am sure that someone can give a trivial answer, but also to indicate to those who may ignore this robust feature of ConTeXt. Also, \externalfigure is a very powerful macro that would justify more complete documentation in the revised reference manual.

Thanks, I just updated the CVS version of gnuplot with your files and gave it
a try: It works with minimals!

Feedback and patches welcome!
No patches I'm afraid. But feedback goes here:
1) The label text of the following key element takes the color of the
preceding key symbol. Minimal example:
set terminal lua tikz fulldoc size 15cm,7cm context
set output 'plot.tex'
set xrange [ 0 : 13 ]
f1(x)=sqrt(x)
f2(x)=sqrt(x*0.8)-3
plot f1(x) lc rgb 'blue', f2(x)
Confirmed. I had the problems with that in my terminal as well, but I
think that it was a buglet in metapost back then; oh, good old
memories ... :) :) :) I didn't check the details about this one.
2) Negative axis labels are set with hyphen instead of proper minus sign,
which should be longer (see example above).
I'm not sure if this should really be fixed automatically or not. In
order to fix this one would have to patch gnuplot core.
I forgot the details how to do it (I can find it out), but you can
configure the layout of labels. In particular you may enclose the
number into math delimiters ($). Maybe something like
set format y $%.1f$
would work (you might want to change the size of left margin then).
Doing any other kind of magic would be a bit dangerous. Keep in mind
that
plot 'x.dat' u 1:(2*$2)
will also fail since TeX will interpret $ as math delimiter. But
changing that behaviour would have other undesirable effects.
3) First I thought luatex hangs but then I noticed TikZ is awfully slow when
drawing plots with large amounts of data points (the tikzpicture had about
3000 lines). I can speed this up by reducing the size by invoking plot with:
plot gawk '(NR-1)%10 == 0 {print $0}' fileWithLotsOfData using [...]
I wonder if there is a smarter way to do this in gnuplot.
Using bitmap terminals. A while back I was dreaming about having
mixed-mode with one terminal creating text labels and the other one
(png for example) drawing the plot. But this needs some extra
programming effort.
You would stumble against the same problem when using PS or PDF
terminal, maybe only at a slightly bigger number of points.
What I did for my theory of chaos reports and the million-of-points
plots in my thesis was to create an empty plot with ConTeXt terminal,
create a borderless plot with PNG and then manually insert PNG into
the generated ConTeXt output, which you could do with TikZ output as
well. It requires more effort, but there is no other way to speed up
vector graphics. They are simply not suitable for drawing millions of
points on the same plot.
(Gnuplot also has a keyword 'every' to reduce the number of points,
but in my case I wanted to plot all of them.)

set output 'randomLua.tex'
replot
Now look at the timing of processing the output files with context (final run
only):
context randomCtx.tex - 3.150 seconds.
context randomLua.tex - 23.658 seconds.
Further increasing the number of points to 15000 results in 8.978 vs. 62.878
seconds. Quite a big difference in processing time!
(Gnuplot also has a keyword 'every' to reduce the number of points,
but in my case I wanted to plot all of them.)
True, but suppose you don't have evenly spaced data points. Then you don't want
every other line but one point every 5 kilometres or something the like.
Especially for line drawings it would be beneficial not to place every single
point. Instead consecutive points should be skipped if they are close to each
other (with regard to plot units) - it makes no sense to include points which
you won't see anyway. This could be done by defining a grid with a certain
(user defined) resolution and rounding the coordinates (plot units) of a line
point to the nearest grid node. All consecutive line points falling on the same
grid node should not be passed on to terminal drivers. The psxy utility of GMT
(http://gmt.soest.hawaii.edu/) does this for instance. I am not aware of such a
functionality within gnuplot but it would be a nice feature.
Best wishes,
Florian

I am not aware of such a functionality within gnuplot but it would be a nice feature. But this is an issue of Gnuplot, not something that a terminal writer is supposed to think of. One thing that I did implement in ConTeXt was that if I get instructions move_to(10,3) line_to(11,8) line_to(11,8) line_to(11,9) then one line_to(11,8) will be ignored (resolution is hard-coded in the terminal, but you could draw a smaller plot and then magnify it which would seemingly decrease resolution). But in most cases that wouldn't really help. About the timing difference between set term context and set term lua context: it is quite possible that metapost library is much faster than TikZ which uses TeX-based macros. TeX might be slower in calculations than metapost (which uses C for low level calculations) and TikZ is not optimized for drawing ten-thousand segments. And Hans really tried hard to optimize the code. Processing the output with ConTeXt is also at least ten times slower that outputting straight to PS or PDF and if you try ConTeXt MKII it is about two times slower than MKIV. You probably didn't have a chance to try the first implementations of ConTeXt terminal for gnuplot. It needed 10 minutes for 13 ordinary plots and it ran out of memory if I tried to plot 14 of them!!! (The reason was the usage of btex text etex constructs which lead to ConTeXt runs inside metapost runs inside ConTeXt runs, all doubled, maybe the labels were compile even four times, usually with a separate instance of ConTeXt for each plot.) Now compare that speed difference and the enormous optimization that Hans implemented back in 2006 ... The slow speed of TikZ is not something that you could do much about. There might be some tiny room for optimization in gnuplot-lua-tikz-common.tex, but hardly any. LuaTeX-based TikZ could be reimplemented and that would bring most benefits, but since Till almost-quit the project and since it works out-of-the-box with pdfTeX macros it is highly unlikely to happen. But yes, it would be nice if also ConTeXt terminal would be included. It still doesn't support raw images, but most other features are present.

[NTG-context] ConTeXt mkiv and Drupal
Dear Contextators, Has anyone tried to process TeX files written for ConTeXt mkiv in Drupal (http://drupal.org/)? To be more precise, there exists a so-called filter DruTeX (http://drupal.org/project/drutex) which can process LaTeX files for viewing them in a web page, but since my TeX files are written for ConTeXt, I wonder if there is a simple way to do the same in Drupal with ConTeXt. Or maybe I am going the wrong direction? Should I export through mkiv my TeX files to some other format than TeX for being understood by Drupal? Actually my documents are essentially one page each, without any complicated layout or graphics: there is only some text, and items within two or three sets of \startitemize, \stopitemize. But they do contain maths and I would like to have them on the web pages. Thanks in advance for any insight.

Feedback and patches welcome!
No patches I'm afraid. But feedback goes here:
1) The label text of the following key element takes the color of the
preceding key symbol. Minimal example:
set terminal lua tikz fulldoc size 15cm,7cm context
set output 'plot.tex'
set xrange [ 0 : 13 ]
f1(x)=sqrt(x)
f2(x)=sqrt(x*0.8)-3
plot f1(x) lc rgb 'blue', f2(x)
Confirmed. I had the problems with that in my terminal as well, but I
think that it was a buglet in metapost back then; oh, good old
memories ... :) :) :) I didn't check the details about this one.
2) Negative axis labels are set with hyphen instead of proper minus sign,
which should be longer (see example above).
I'm not sure if this should really be fixed automatically or not. In
order to fix this one would have to patch gnuplot core.
I forgot the details how to do it (I can find it out), but you can
configure the layout of labels. In particular you may enclose the
number into math delimiters ($). Maybe something like
set format y $%.1f$
would work (you might want to change the size of left margin then).
Doing any other kind of magic would be a bit dangerous. Keep in mind
that
plot 'x.dat' u 1:(2*$2)
will also fail since TeX will interpret $ as math delimiter. But
changing that behaviour would have other undesirable effects.
3) First I thought luatex hangs but then I noticed TikZ is awfully slow
when drawing plots with large amounts of data points (the tikzpicture had
about 3000 lines). I can speed this up by reducing the size by invoking
plot with:
plot gawk '(NR-1)%10 == 0 {print $0}' fileWithLotsOfData using [...]
I wonder if there is a smarter way to do this in gnuplot.
Using bitmap terminals. A while back I was dreaming about having
mixed-mode with one terminal creating text labels and the other one
(png for example) drawing the plot. But this needs some extra
programming effort.
As I recall, I posted a patch the last time this discussion came up.
It turns off text output from the png terminal without affecting any
other graphical elements. My though was that it could be the basis
of a pdflatex terminal class that works the same way as the current
epslatex terminals. I can post it again, or upload it to SourceForge
if it isn't there already.
Ethan
You would stumble against the same problem when using PS or PDF
terminal, maybe only at a slightly bigger number of points.
What I did for my theory of chaos reports and the million-of-points
plots in my thesis was to create an empty plot with ConTeXt terminal,
create a borderless plot with PNG and then manually insert PNG into
the generated ConTeXt output, which you could do with TikZ output as
well. It requires more effort, but there is no other way to speed up
vector graphics. They are simply not suitable for drawing millions of
points on the same plot.
(Gnuplot also has a keyword 'every' to reduce the number of points,
but in my case I wanted to plot all of them.)
