embedding ConTeXt code in an xtable
by Sander Maijers 17 Jun '13

17 Jun '13

I am now using xtable to have an XMLish document to store a table. How I can embed ConTeXt code like $\Delta{}N_{\text{test}}$ in the external XML file file with the table? In other words, having mathematical notiation in the table header? I tried various things such as: \expanded{\xmlflush{#1}}

Output from Context standalone (actual version) has wrong utf-8 encoding
by Christian Prim 17 Jun '13

17 Jun '13

Hi list rendering a very easy formula with greek text in it produces a pdf-document that has not a valid utf-8 string. I use evince for displaying pdfs under ubuntu linux. The document appears correctly on the screen but stops printing after a greek letter in a formula. The error-report says: Internal Error: cairo context error: input string not valid UTF-8 The same document compiled in live.contextgarden.net doesn't produce a mistake and can be printed with evince. I can still print the document correctly using 'lpr name.pdf', so it's not a big problem for me. But I don't know if that could be a problem for someone else. Test-Document: \starttext $3\omega$ \stoptext Tell me, what I can do to help. Thanks Christian

Hebrew vowel placement in ConTeXt.
by Michael Ash 17 Jun '13

17 Jun '13

I am new to ConTeXt and very impressed. Much thanks to Hans Hagen and Idris Samawi Hamid for an excellent introduction. I am using the Hebrew Ezra SIL Hebrew Unicode Fonts. My question concerns the placement of the Hebrew vowel points ("niqqud"). For most letters, the vowel points are placed too far to the left, as opposed to centered directly under the letter. A short example follows. For some of the letters, e.g., "Hebrew Letter Alef With Qamats" (kind of a t-shaped vowel underneath the alef), the vowel is correctly centered. For others it appears incorrectly to the left. (This may be connected with whether the letter+vowel is packaged as a single character or whether it is being composed on the fly.) I have used the same font in several predecessor programs (the makor package for lamed and the cjhebrew package for LaTeX) and the vowels points are placed correctly. Please let me know if you have any suggestions regarding adjusting the placement of the vowel points. (ConTeXt version info is at the end of the message.) Thank you, Michael \definefontfeature[hebrew][arabic][script=hebr] \definefont[hebrew][name:ezrasil] \starttext Zephania 3:8 includes all of the letters in the Hebrew alphabet, the equivalent of \quotation{The quick brown fox jumps over the lazy dogs} in English. \startalignment[left] \textdir TRT \hebrew לָכֵן חַכּוּ־לִי נְאֻם־יְהוָה לְיוֹם קוּמִי לְעַד כִּי מִשְׁפָּטִי לֶאֱסֹף גּוֹיִם לְקָבְצִי מַמְלָכוֹת לִשְׁפֹּךְ עֲלֵיהֶם זַעְמִי כֹּל חֲרוֹן אַפִּי כִּי בְּאֵשׁ קִנְאָתִי תֵּאָכֵל כָּל־הָאָרֶץ׃ \stoptext Here is the ConTeXt version and operating system: $ uname -a Linux mash-laptop 3.8.0-23-generic #34-Ubuntu SMP Wed May 29 20:24:54 UTC 2013 i686 i686 i686 GNU/Linux $ context --version mtx-context | ConTeXt Process Management 0.60 mtx-context | mtx-context | main context file: /usr/share/texmf/tex/context/base/context.mkiv mtx-context | current version: 2013.06.04 23:52

[***SPAM***] Celsius or Me

I am using the latest TeXLive update version of MKIV (used tlmgr to update). In a compile time message Context says that it doesn't like: " !

Hi, as far as I have understood MathML, elements tagged with mathvariant=bold should be set upright bold, not bold-italic. Could this be corrected, please? Thank you very much!

Learning ConTeXt from the Ground Up
by Malte Stien 16 Jun '13

16 Jun '13

Hello Everyone, I have been using ConTeXt for over a year now and worked out how to do most things I need to do. Every now and then, though, I need to do something that I cannot find any information about and in most cases I post a question here on the forum. I have received great help here over the months and like to thank everyone who took the time to answer my questions. The other day, however, I had a problem, posted a message here, got an answer and the answer did not quite work; I went back to the forum, got more help... In the process I realised that I should have been able to work this out myself; I was not even able to tweak the first answer and make it work. I am an IT engineer myself, but with little time (I guess I am not unique here) and even less experience in TeX. I guess what I am saying is, that I would like to gain a much deeper understanding of ConTeXt which will allow me to "program" in ConTeXt rather than just using the documented command. To gather information about ConTeXt I have - read the ConTeXt Reference Manual (http://pmrb.free.fr/contextref.pdf) - bought a couple of the published books by Hans Hagen - started reading the "TeX book" by Donald Knuth I have even briefly flirted with the idea of switching to LaTeX mainly because it would mean having a lot more literature and a broader community at my disposal. However, I just prefer the command structure and output of ConTeXt. Can anyone relate to my problem? Am I on the right track? What else should I be doing or reading to really break into ConTeXt? Regards, Malte. PS: Just to be clear; I don't mean for the above to be conceived as shortcomings of ConTeXt, rather I think of them as shortcomings of myself. The developers of ConTeXt have done a fantastic job and I really enjoy writing in ConTeXt and looking at the output. -- “The Electric Monk was a labour-saving device, like a dishwasher or a video recorder...

Alignment of inmframed
by Aditya Mahajan 16 Jun '13

16 Jun '13

\inmframed (and by extension \definemathframed[...][location=low,...]) does not get the right vertical space. For example, \starttext \startformula \ln (1+x) = \inmframed{x - {\frac {x^2}{2}}} + \frac{x^3}{3}-\cdots. \stopformula \stoptext Note that the two fractions do not align at the horizontal bar. Is it possible for all expressions to be aligned at the math axis? Aditya

[***SPAM***] Float placement
by Tethys 15 Jun '13

15 Jun '13

I'm trying to typeset a book. It has two columns, and some floating diagrams. My problem is that the floats aren't going where I want them to and I can't work out how to fix it. My input source looks something like: \startcolumnset[foo] \subject{Blah} aaaa aaaa aaaa aaaa aaaa aaaa aaaa \placefigure[here]{First diagram} {\externalfigure[diagram1.jpg][width=2.3in]} bbbb bbbb bbbb bbbb bbbb bbbb bbbb \placefigure[here]{Second diagram} {\externalfigure[diagram2.jpg][width=2.3in]} cccc cccc cccc cccc cccc cccc cccc \placefigure[here]{Third diagram} {\externalfigure[diagram3.jpg][width=2.3in]} dddd dddd dddd dddd dddd dddd dddd What I expect to get out is a page something like this (excuse the ASCII graphics): +-----------------------------------------+ | | | Blah cccc cccc cccc | | ---- cccc cccc cccc | | cccc cccc | | aaaa aaaa aaaa | | aaaa aaaa aaaa +--------------+ | | aaaa | ############ | | | | ############ | | | +--------------+ | ############ | | | | ############ | | ############ | | | | ############ | | ############ | | | | ############ | | ############ | | | +--------------+ | ############ | | | First diagram | ############ | | | +--------------+ | | bbbb bbbb bbbb Third diagram | | bbbb bbbb bbbb | | bbbb bbbb dddd dddd dddd | | dddd dddd dddd | | +--------------+ dddd dddd dddd | | | ############ | dddd dddd dddd | | | ############ | dddd dddd dddd | | | ############ | dddd dddd dddd | | +--------------+ dddd dddd | | Second diagram | | | | cccc cccc cccc | | cccc cccc cccc | | | +-----------------------------------------+ What I'm actually getting out is this: +-----------------------------------------+ | | | Blah +--------------+ | | ---- | ############ | | | | ############ | | | aaaa aaaa aaaa | ############ | | | aaaa aaaa aaaa +--------------+ | | aaaa Second diagram | | | | +--------------+ +--------------+ | | | ############ | | ############ | | | | ############ | | ############ | | | | ############ | | ############ | | | +--------------+ | ############ | | | First diagram | ############ | | | | ############ | | | bbbb bbbb bbbb | ############ | | | bbbb bbbb bbbb | ############ | | | bbbb bbbb +--------------+ | | Third diagram | | cccc cccc cccc | | cccc cccc cccc dddd dddd dddd | | cccc cccc cccc dddd dddd dddd | | cccc cccc cccc dddd dddd dddd | | cccc cccc dddd dddd | | | | dddd dddd dddd | | dddd dddd dddd | | dddd dddd dddd | | | +-----------------------------------------+ Even though there is sufficient space in the first column, the second float is always being moved up to the top of the second column. I've tried pretty much every combination of here, force and always as the location keyword for the \placefloat, but it doesn't make any difference. Any idea what I can do to get the placement I want? The deadline for going to press is rapidly approaching and I'm getting a little concerned! Thanks, Tet

UWIN?
by Bill Meahan 15 Jun '13

15 Jun '13

Out of curiosity, has anyone tried porting ConTeXt to the UWIN environment? UWIN is very much like cygwin in being a "Unix on Windows" environment. However, it is not based on GNU but is Real Unix code from AT&T Bell Labs. Many of the utilities are simply the latest versions of the original Version 7 Unix utilities, others are from BSD, System III and System V. The shell is genuine ksh93, not pdksh or bash/dash. There is a POSIX dll to provide a complete POSIX api. This is AT&T's own, not the "POSIX subsystem" from Microsoft. The cc command is a wrapper for Visual C, gcc or whatever you have. Instead of the usual autoconf..configure..make..make install dance you can use nmake. I can run the usual Windows context with a bit of fiddling but it would be nice to use the regular setuptex shell script et. al. -- Bill Meahan Westland, Michigan
