XML in ConTeXt & verbatim text
by Richard Gabriel 17 Dec '04

17 Dec '04

Hi all, I'm back here with the following problem: I'm processing XML files (DocBook DTD) which also may contain the <programlisting> tag with some preformatted text. In a sample TeX file, I've tested the following: \starttyping <somecontext> <variable name="Var"> Value of Var </variable> </somecontext> \stoptyping This works and the result is great. So I defined a macro to process the <programlisting> tag from the XML file: \defineXMLenvironment[programlisting]{\starttyping}{\stoptyping} This causes an error while processing. Most probably the \starttyping command breaks things inside the \defineXMLenvironment macro... Any guess how to solve this issue? Many thanks! Richard

floats pb in a list
by olivier Turlier 17 Dec '04

17 Dec '04

Hi contexers, I try writing step by step howtos for Autocad courses. I've borrowed (one more time) Hans example code written around p83 in cont-eni.pdf for combined items, and rename definitions. I'm unable to get correct float placement in a such list, even with small figures. On each new page, the float move towards topleft, above it's "anchor".

How to get default Dutch language Context in TeXShop on Macos X
by Robert Kroon 16 Dec '04

16 Dec '04

Hi, Recently I've installed Gerben Wierda's teTeX distributon incl. ConTeXt on my iMac (Macos X, 10.3.6). Now I'm trying to learn ConTeXt. I'm marking up my documents in TeXShop, version 1.34. I can typeset small ConTeXt documents and generate PDF-files as long as the type setting commands are in English. However, I would like to use Dutch type setting commands like: \starttekst Dit is een test \stoptekst When I typeset this file from within TexShop I get following output and errors <Begin screen message> TeXExec 5.2.3 - ConTeXt / PRAGMA ADE 1997-2004 executable : pdfetex format : cont-nl inputfile : Context-les1 output : pdftex interface : nl current mode : none TeX run : 1 This is pdfeTeX, Version 3.141592-1.20a-2.2 (Web2C 7.5.3) (/usr/local/teTeX/share/texmf.local/web2c/natural.tcx) kpathsea: Running mktexfmt cont-nl.fmt fmtutil: no info for format `cont-nl'.

Any tips how I can get my Dutch typesetting command from within TeXShop? Many thanks in advance.

bookmarks problems
by Christopher Creutzig 16 Dec '04

16 Dec '04

Salvete, I have two problems with bookmarks: - Preview.App does display the list of bookmarks, but they do not work. The same file has no such problems in Adobe. (There are files with bookmarks that work ok in Preview.App, such as the Adobe JavaScript reference.) - I fail to provide a bookmark different from a chapter title, if that title is not followed by text, but directly by a \section command. Whether I place \bookmark in front of or behind the \chapter command, it affects the next section command with text behind it. \setupinteraction[state=start] \placebookmarks[chapter,section] \starttext \chapter{normal chapter} \section{one} \chapter{\quotation{special} chapter} \bookmark{"special" chapter} \section{two} \section{three} test \stoptext regards, Christopher Creutzig

\placetable and \starttables ... \stoptables

XML & <formula>s
by Adam Lindsay 15 Dec '04

15 Dec '04

Hi all. I want to use XML, but in a non-doctrinaire way: I much prefer TeX formula writing to mathml by hand. I looked at xtag-mml, and the \defineXMLenvironment [formula] looked like just what I wanted. However, when trying it, the XML catcode regime was still in effect, and the backslashes were printed, and didn't act as escapes. Am I missing something in the correct usage, or is support "incomplete"? This is a sample file, showing how I've been trying to use it: \useXMLfilter[mml] \starttext \startXMLdata <formula> t+3+x+t\neq m\alpha\frac\theta\hbar </formula> \stopXMLdata \stoptext Also, what's the status of contml? I like the idea of it as a simple, structural, basic markup that ConTeXt handles with zero effort, but is anyone actually using it? adam -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Adam T.

At a loss how to proceed
by David Arnold 15 Dec '04

15 Dec '04

All, Lately, I've had a number of discussions with the director of disabled student services at our school regarding document preparation for the visually impaired. As a result of these discussions, I am a bit lost as how to proceed with the preparation of mathematics for the web and documents for my course content. I've paid a little attention to the develoment of MathML, but I've always said "Who wants to code like that?" whenever I look at examples. However, today I found: http://www.dessci.com/en/company/press/releases/040722.htm I now realize that software that reads web pages aloud it pretty important. But how do I, in my limited time, prepare documents for multiple purposes? Can I use Context to support all of our students at our school? Just how do I proceed? At a loss.

Division bug in \doMPconcat (supp-pdf.tex)
by Dan Luecking 15 Dec '04

15 Dec '04

I encountered a problem with supp-pdf when I tried to rewrite Knuths "dangerous bend" as a MetaPost figure. Very little change was required to get a good picture, but the "reverse dangerous bend" (obtained by merely reflecting the currentpicture" produced a quite grotesquely distorted picture. I tracked this down to the method used to divide by the determinant of the scaling matrix in \doMPconcat. The division code is the following: \ifdim\dimen16=\onepoint \else \ifdim\dimen16>\MPconcatfactor \onepoint \relax \doMPreducedimen16 \divide \dimen18 \dimen16 \doMPexpanddimen18 \divide \dimen12 \dimen16 \doMPexpanddimen12 \else \divide \dimen18 \dimen16 \doMPexpanddimen18 \doMPexpanddimen18 \divide \dimen12 \dimen16 \doMPexpanddimen12 \doMPexpanddimen12 \fi \fi In the reverse dangerous bend symbol \dimen16 (the determinant in question) is -1 and \MPconcatfactor is 256, so the else part is taken. The division is integer division, so the accuracy (after the two \doMPexpanddimen) is +/- 1pt. This turns values like the following: 58.11118 -61.6534 7.53143 -11.0737 7.52731 -11.06958 c 4.48691 -8.02919 1.99252 -4.2878 1.99252 0 c 1.99252 4.2878 4.48691 8.02919 7.52731 11.06958 c 7.53143 11.0737 58.11118 61.6534 58.1153 61.65752 c into (actual code in from uncompressed pdf output): 58.0 -61.0 7.0 -11.0 7.0 -11.0 c 4.0 -8.0 1.0 -4.0 1.0 0.0 c 1.0 4.0 4.0 8.0 7.0 11.0 c 7.0 11.0 58.0 61.0 58.0 61.0 c Similar problems occur if the figure is rotated. (Theoretically, the determinant is 1, but with only 5 decimal accuracy, the same branch is taken.) Also the \if tests above don't take the sign of \dimen16 into account. There is a lesser problem with multiplication when numbers are less than around 1pt. The pre-division by 256 (\doMPreducedimen) reduce accuracy to less than 3 significant decimal digits (i.e., 8 binary digits). I have written some modifications for supp-pdf that avoid all of these. No pre-division is used because multiplication is accomplished by something like \dimen16 = \withoutpt\the\dimen0 \dimen6 and division is accomplished by computing 1/D and multiplying. Since the numerator (1) is fixed, this one division can be arranged for maximum accuracy. I do this by halving D until it is less than 1pt, keeping track of the number of halvings required. Then I divide 2^30 by D, then double the result 2 fewer times than than D was halved. This guarantees at least 14 binary places accuracy, or the number of places in D, whichever is smaller. My speed tests show that the resulting code is as fast or slightly faster than the current code. Further efficiency could be gained by performing the calculation of D outside the loop of calls to \doMPconcat (I have not done this yet). The current state of my code can be found at http://comp.uark.edu/~luecking/tex/supp-pdf.mod and a stripped down version of the reverse dangerous bend code that shows the problem is http://comp.uark.edu/~luecking/tex/rdbend.mp Comments are welcome. I hope at least the division can be made more accurate in the context distribution. Dan Luecking Daniel H. Luecking Department of Mathematical Sciences University of Arkansas
