Non-printable Unicode control characters
by Khaled Hosny 17 Aug '08

17 Aug '08

Unicode has many "control characters" that only control text behaviour and shouldn't be rendered visually in the text, such as Bidi_Control and Join_Control chars (see http://www.unicode.org/Public/5.1.0/ucd/PropList.txt and http://unicode.org/Public/UNIDATA/UCD.html) Currently, ConTeXt handles ZWJ and ZWNJ, but other characters get rendered if the font has glyphs for them or make no effect at all if the font has no glyphs for them. I think that the optimum behaviour is to make those characters affect text formatting while not visually rendered whether the font has glyphs for them or not. It might be also useful if we can enable rendering those characters manually, for drafts and such. Regards, Khaled -- Khaled Hosny Arabic localizer and member of Arabeyes.org team

Some Arabic ligatures get rendered twice
by Khaled Hosny 16 Aug '08

16 Aug '08

Some Arabic ligatures get rendered twice, I think this happens when a ligature can be divided into subligatures, say ABC ligature where the font has an AB ligature, in this case A+B+C get rendered as ABC+AB. See the attached example. Regards, Khaled -- Khaled Hosny Arabic localizer and member of Arabeyes.org team

Enabling character mirroring without enabling "implicit bidi"
by Khaled Hosny 16 Aug '08

16 Aug '08

Currently, \enablecharactermirroring[1] also enables "implicit bidi", but, unfortunately, current ConTeXt bidi implementation isn't very useful. I know this is work in progress, but I like to be able to have simple character mirroring i.e. \textdir TRT will mirror all brackets as it currently make any text RTL. With the current situation, I'm almost unable to typeset any real Arabic document. Regards, Khaled -- Khaled Hosny Arabic localizer and member of Arabeyes.org team

updating to new release
by Alan Bowen 16 Aug '08

16 Aug '08

I updated to the latest ConTeXt but now get the following error message when I process my files (using TeXShop as the front end, and TeXLive 2007): ConTeXt ver: 2008.08.04 10:10 MKII fmt: 2008.8.9 int: english/english language : language en is active system : cont-new loaded (/usr/local/texlive/2007/texmf-dist/tex/context/base/cont-new.tex FatalError : Your format does not match the base files! FormatVersion : 2008.08.04 10:10 MKII FilesVersion : 2008.08.09 18:12 The updating process included sudo texhash sudo texexec --make --all so I am puzzled about why the problem occurs. Note: texmfstart ctxtools --contextversion returns CtxTools | context version: 2008.08.09 18:12 (/usr/local/texlive/2007/ texmf-dist/tex/context/base/context.tex) CtxTools | context version: 2008.08.09 18:12 (/usr/local/texlive/2007/ texmf-dist/tex/context/base/cont-new.tex) Reinstalling ConTeXt ver: 2008.08.04 obviates the problem.

Partly OT: some luatex questions
by Ulrike Fischer 15 Aug '08

15 Aug '08

I'm currently trying if I can use luatex on my miktex installation and together with LaTeX. I have downloaded the executable (Version snapshot-0.29.0-2008071816) from the context-minimals and made a simple texmf.cnf and build some formats (the formats don't contain something luatex specific, they simply load latex.ltx). Things works quite fine, my (pdf)lualatex is running and is finding all the ressources (fonts, styles etc) from my miktex-trees. But I have some problems I don't know how to solve. 1. In the following document there is no space between the a and the y: \documentclass{article} \begin{document} \noindent a\\y \bigskip a\par y \end{document} It looks as if the lines have only the depth from their content. 2. I found here some code to use truetype and opentype fonts: http://luatex.bluwiki.com/go/Use_a_TrueType_font But while testing the code I run in two two problems: a) I tested it with a latin modern font and arial and with both fonts all lines of a text are printed one above the other. It looks as if none of the lines have a height and a depth. b) I also tried MnSymbol5.otf and there I get an error "invalid character". (I tried to get an "A"). With xetex the font works fine. I would be quite grateful if someone could tell me how to solve this problems. -- Ulrike Fischer

Caption on the right side of a figure
by Flavien Lambert 15 Aug '08

15 Aug '08

Dear all, I try - as indicated in the title - to put the caption of a figure on its right side. I used (among other attempts) \setupcaptions[location=high] and \setupfloat[figure][location=left] but the figure is still on the right side. Can you give me the good options for inverting captions and figures ? Thanks in advance. -- Flavien. ---------------------------- "Quantum objects are completely crazy but, at least, they are all crazy in the same way." R.P. Feynman.

stay on grid in double column
by Jelle Huisman 14 Aug '08

14 Aug '08

Hi, I have text with a small intro section in a double column environment. The main text is set on a grid and the intro text is slightly off-grid with a \vskip -2pt before and a \vskip 2pt after the intro. As this sample shows this works fine, until the intro text is broken over two columns. In that case the last part of the intro starts on grid (in the second column) and the main text is moved off-grid and does not longer register with the main text in the first column :( [see example code]. Is there is way to detect and prevent this (automatically)? Can ConTeXt remember that it is setting some text \vskip-ped, while it is breaking the current paragraph over columns? (Basically I want to keep all the B's on the grid and all the A's \vskipped.) Thanks, Jelle % sample code \definecolumnset[doublecolumn][n=2] \setupcolumnset[doublecolumn][2][distance=5mm] \setupbodyfont[12pt] \setupinterlinespace[line=11pt] \setuplayout[grid=yes] \showgrid \starttext \startcolumnset[doublecolumn] \ss \subject{Header} \dorecurse{2}{\vskip -2pt This text is vskipped. A \dorecurse{40}{ aa aa} \vskip 2pt % intro text This text should stay on the grid. B \dorecurse{270}{ bb bb}} % main text should stay on grid \stopcolumnset \stoptext

letter module
by Roger Mason 14 Aug '08

Hello, I just downloaded the letter module and installed it by unzipping the t-letter.zip file into /usr/local/context_minimal/. When I try a test letter: \usemodule[letter] \starttext \startletter It is raining again. \stopletter \stoptext context fails with: systems : system commands are enabled system : module letter not found (/usr/local/context_minimal/tex/texmf-local/tex/context/base/sort-lan.tex loading : Context Sorting Macros (languages) (/usr/local/context_minimal/tex/texmf-local/tex/context/base/sort-lan.mkii)) (/usr/local/context_minimal/tex/texmf-local/tex/context/base/pdfr-def.tex) systems : begin file ltrtest at line 3 ! Undefined control sequence. l.4 \startletter ? The log file tells me "ConTeXt ver: 2007.08.08 14:35 MKII fmt: 2008.5.6 int: english/english" This is on a Gentoo Linux system. Thanks for any help, Roger
