sagemath in context
by curiouslearn 28 Apr '09

28 Apr '09

Hi, I know that Context is developing rapidly and the top guys here are all very busy with these development efforts. But I thought I would just float this idea. There is an open source mathematics software system called sagemath which aims to be a viable substitute to Mathematica and Maple. The link is http://www.sagemath.org/ There exists a latex package called sagetex, which allows using sagemath functions from within latex. The following link on ctan has some examples http://www.ctan.org/tex-archive/macros/latex/contrib/sagetex/ Do you think it is possible to do a similar thing in Context? It would be really cool if this functionality is added to Context. What do the experts here think?

startregister produces strange page range ("1-2-3")
by Sanjoy Mahajan 28 Apr '09

28 Apr '09

With the following minimal file, the index entry for Knuth has the strange page range "1-2-3" rather than "1-2, 2-3". Adding \input knuth a few times in between the two start..stopregister stanzas gives a correct page range (so maybe that change hides the problem). I'm using ConTeXt 2008.10.31 (Mk II) from the Debian unstable packages. The live context (2009.03.06) produces a blank index with the pdftex engine, so I'm CC'ing Patrick in case that problem is separate. \starttext \startregister[index][Knuth]{Knuth} \dorecurse{5}{\input knuth } \stopregister[index][Knuth] \startregister[index][Knuth2]{Knuth} \dorecurse{5}{\input knuth } \stopregister[index][Knuth2] \completeindex \stoptext -Sanjoy

Letter module – new feature (mkiv only)
by Wolfgang Schuster 27 Apr '09

27 Apr '09

Hi, with the latest version of my module you get a overview of the loaded files at the end of the log file, be aware this is a mkiv only feature i will not implement this for mkii. To show you how this looks like here is the output from my test document: correspondence : t-correspondence.tex: 2009.04.27 correspondence : t-letter.tex: 2009.02.13 correspondence : default.nli: 2009.03.31 correspondence : dinb.nls: 2009.02.14 correspondence : default.nls: 2009.03.27 correspondence : label.nle: 2009.02.13 correspondence : addrentry.nle: 2008.12.26 Wolfgang

Re: [NTG-context] [OS X TeX] PSTricks in Context
by Wolfgang Schuster 27 Apr '09

27 Apr '09

Dear Mr. Arnold, questions regarding ConTeXt and modules for ConTeXt are better asked on the ConTeXt mailing list and if you would have done this I could have given you the following answer. The default output format for ConTeXt is PDF since about three years while PSTricks needs the files in PostScript format which requires a intermediate DVI file. To get a DVI file with ConTeXt you could set it either with \setupoutput[dvi] in your document or you use the backend switch on the command line, because the code between the PSTRICKS-environment is written in a external file which is converted to dvi, ps and pdf you have to do this in the pstric-module and not in your document. In my own installation I made a copy from the file m-pstric.tex and added the \dostartTEXapplication macro from the page-app.tex file where I now changed the line \executesystemcommand{texexec --once --batch \bufferprefix \@@texapp.tex}% to \executesystemcommand{texexec --once --batch --backend=dvips \bufferprefix\@@texapp.tex}% and switched from ps2pdf command to pstopdf %\executesystemcommand{ps2pdf \bufferprefix\@@texapp.ps \bufferprefix\@@texapp.pdf}% \executesystemcommand{texmfstart pstopdf \bufferprefix\@@texapp.ps \bufferprefix\@@texapp.pdf}% to get a cropped page for the image. As a last change I added the following two definition to m-pstrics.tex because pstricks.tex use them but are not defined in ConTeXt: \letvalue{@unused}\plussixteen \letvalue{alloc@}\gobblefivearguments After these changes I was able to produce PSTricks images in ConTeXt but people had use never given enough time on the ConTeXt list to answer their questions and fix the problem and so PSTricks support is broken since a long time and this will not change. Best regards, Wolfgang Schuster

Why searching fonts in xetex is so slow?
by Yue Wang 25 Apr '09

25 Apr '09

Hi, When I use XeTeX, font searching through texmf- tree is very slow. search font through fontconfig is very fast. plain TeX or LaTeX does not have that problem. why is that? anyway to improve it? Yue Wang

Textbackground bug [repost]

[I got no answers to my previous post] With page imposition, in luatex, background overrides text \setuppapersize[A4][A3,landscape] \setuparranging[2SIDE] % <--bug here \setupcolors[state=start] \definetextbackground[intro] [backgroundcolor=gray, backgroundoffset=.25cm, offset=.5cm, frame=off, location=paragraph, color=white] \definetextbackground[subintro] [backgroundcolor=texcolorfour, backgroundoffset=0pt, offset=0pt, frame=off, location=text, color=blue] \starttext \starttextbackground[intro] A rather common way to draw attention to a passage, is to add a background.
