[sage-support] Re: convertor Sage - TeX - PDF
Hi Marik, Thanks for that. For some reason, it does not work on the pdf I downloaded, but if I create a pdf myself, it works. The comment in the pdf could mention right-click to make it clearer. Great work! I hope this script will make it into sage some time!! It still produced a lot of error messages and formatting glitches with the worksheet I tried it on, but it is a good start.

I have a similar but slightly different request. When I have a plot in sage, say of a function x- sin(x), I would like to be able to do something like what is explained in http://www.texample.net/tikz/examples/gnuplot-basics/ for gnuplot and pgf. This means, extracting the relevant numerical values and leaving pgf deal with axis, ticks, grid, captions and additional stuff in order to keep the same fonts as in LaTeX for both the text and the pictures. Any idea ? --~--~-~--~~~---~--~~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org -~--~~~~--~~--~--~---

Any idea ? In addition to what William said, I think we ought to eventually support pgf (either through matplotlib or on our own). This would be very handy in sagetex, for example. Note that we already use pgf to draw graphs (vertex/line things) in latex. There has been interest in a pgf backend to matplotlib (what we use to actually draw 2d graphics most of the time): http://www.mailinglistarchive.com/html/matplotlib-us...@lists.sourceforge.net/2009-08/msg00358.html I played with making a pgf backend to matplotlib once, but ran out of time to experiment with it.

I have modified the skript a little bit.
Great, I have seen that you improved it a lot! Thanks.
I have two another improvements (and changed the script at
http://user.mendelu.cz/marik/sage/sage2tex )
First:
The following lines can be used to process tables created by
html.table command, see the file http://user.mendelu.cz/marik/sage/integral.pdf
obsah=string.replace(obsah,table class=\table_form\,{\
\offinterlineskip\\halign{\\vrule \\vrule width 0 pt height 14pt depth
5pt # \\vrule # \\cr\\noalign{\\hrule})
obsah=string.replace(obsah,tbody,%)
obsah=string.replace(obsah,/tbody,%)
obsah=string.replace(obsah,/table,\\noalign{\\hrule}}})
obsah=string.replace(obsah,tr,\\global\\def\\optcr{\\vskip 2
pt\\hrule})
obsah=string.replace(obsah,tr class =\row-a\,\\global\\let\
\optcr\\relax{})
obsah=string.replace(obsah,tr class =\row-b\,\\global\\let\
\optcr\\relax{})
obsah=string.replace(obsah,/tr,\\cr\\noalign{\\hrule\
\optcr})
obsah=string.replace(obsah,th,\\quad\\textbf{)
obsah=string.replace(obsah,/th,} )
obsah=string.replace(obsah,td,\\quad )
obsah=string.replace(obsah,/td, )
Second: TeX does not understand \textcolor[HTML]{ff}{stuff}. So
these lines convert into \textcolor[HTML]{FF}{stuff} (replacement
for previous version of this regexp substitution)
regular=re.compile(rspan style=\color: #(.*?);\)
obsah=regular.sub(lambda x: \\textcolor[HTML]{+x.group(1).upper()
+}{,obsah)
You can find the new version of the script at:
http://www.math.tugraz.at/~huss/sage/sws2tex.py
And here are example outputs:
http://www.math.tugraz.at/~huss/sage/sage_tutorium.pdf
http://www.math.tugraz.at/~huss/sage/sws2pdf_test.pdf
Would you agree to release your initial script under the GPL or an
other Sage compatible
licence? I hope this can be improved to a point where it could be
included into Sage, for
this it needs a proper licence.
I am O.K. with any free licence, GNU GPL, Creative Commons or any
other.
In fact, the script was so simple that I was not thinking about any
licence.
I have no skills in programing in Python or any other object oriented
langugae and you cannot expect, that I can help to improve it into a
form which could be used for sufficiently big set of sage worksheets,
including complicated html, 3D graphics, included external pictures
and some other things.
Would you like to work a bit deeper on conversion between Sage and
TeX? If yes, then everything is up to you and from my point of view it
is sufficient to state somewhere, that the initial version was based
on the work of Robert Marik.
Thank you very much
Robert

btw: another improvement in current http://user.mendelu.cz/marik/sage/sage2tex
(from October 30) are lines
lines 46-48
worksheet=open(sage_worksheet/worksheet.txt,'r')
title = worksheet.readline()

lines 184-190 from TeX preamble:

and line 206
+\\def\\titlename{+do_substitutions(title)+
this is used to write name of the author and name of the worksheet in
bottom line.
The name of the author is hardwired in my version, however it could be
perhaps passed from command line or config file.
I am thinking also on possibility how to translate the stuff D
[0,0]\left(y\right) into y''. I think that the simplest solution is to
allow users custom substitutions specified from command line or from
config file. And I think that there is a trac which will fix this
notation.
Questions to more experienced Sage users and developers:
--
when exporting sws file and unpacking, I do not understand the
following
1. what is the difference between sage_workseet/worksheet.html and
sage_workseet/worksheet.txt ? (neglecting the ffirst two lines, the
rest is identical in my notebooks)
2. My worksheet.html looks like this
{{{id=1|
x,y=var('x y')
///
}}}
{{{id=2|
plot(sin(x),(x,0,3))
///
htmlfont color='black'img src='cell://sage0.png'/font/html
}}}
{{{id=3|
plot(sin(x),(x,0,6),filename=sage0.pdf)
///
htmlfont color='black'img src='cell://sage0.pdf'/font/html
}}}
{{{id=4|
plot3d(x^2-y^2,(x,-1,1),(y,-1,1),viewer='tachyon')
///
}}}
{{{id=5|
///
}}}
Why is line like htmlfont color='black'img src='cell://
sage0.png'/font/html missing in the output for cell id=4. The
file with the picture is in the directory and the picture is in the
notebook - exactly like for output of 2d plot in cell id=2. Is there
any reason to skip it, or is it a bug?
Thank you.
Robert
