placing a paragraph with non-standard interlinear spacing onto the grid
by Talal Al-Azem 03 Oct '10

03 Oct '10

Dear all, This is important for anyone working with mixed language (font) texts. In my example, the overall document is Latin-based (e.g. English), with a paragraph of Arabic text; I want this Arabic paragraph as a whole to fit onto the grid (though obviously the individual Arabic lines of the paragraph would not). Currently, when I typeset an English paragraph, followed by an Arabic paragraph, followed by an English paragraph, the second English paragraph is no longer on the grid, having been throw off by the Arabic one. I'm looking for some way to automatically calculate and fill in the vspace needed for this. This is not the same as the issue of an Arabic word or phrase (or mathematic formula) being typeset in the midst of Latin text, as discussed http://www.mail-archive.com/ntg-context@ntg.nl/msg46163.html. Having read a few other matters on the mailing list (largely involving Idris and Hans), I'm sure it's possible, but I can't figure it out. Any help would be most appreciated. Kind regards, Talal

Lettrines in MkIV
by Philipp Gesang 03 Oct '10

03 Oct '10

Hi all, the lettrine module leads to an error with this example and MkIV. MkII is fine. ····8<··························································· \usemodule[lettrine] \starttext \chapter{And Now: an Error} \lettrine{E}{rror} \stoptext ····8<··························································· * With Luatex 0.63.0-2010091123 I get an ``error on line 6 in file ../environ.tex: Attempt to double-free glue node 1001, ignored ...`` * Can be circumvented via “\dontleavehmode”. * Never ran into a “glue node” error before; is there general rule how to avoid them? Thanks for any advice, Philipp PS: Taco, the french blindtext in lettrine-doc.pdf has an issue concerning guillemets, which are rendered as inverted question marks and exclamation marks. I wasn't able to compile the document myself so unfortunately I can't send a patch. -- () ascii ribbon campaign - against html e-mail /\ www.asciiribbon.org - against proprietary attachments

[NTG-Context] How to compute correct page number for handout
by Pierre-François Bonnefoi 03 Oct '10

03 Oct '10

Hello, I'use extensively context to write my lecture notes and for all of my printing needs. For my students, I've made some lecture presentations in color, and I print them in black&white, with four pages on one page for the handout. I would like to compute a correct Table of contents according to the handout : so to divide the current page number by four to get a correct page number for the handout. \def\ChapterPrefix#1{\the\numexpr#1/4 \relax} \setupcombinedlist[content][level=1] \setuplist[chapter][after=,before=,numbercolor=yellow,numbercommand=\underbar,pagecommand=\ChapterPrefix] That doesn't work, and I've some difficulties to figure how computation is performed in e-TeX... Could you help me to resolve this issue ? Kind regards, Pierre-François Bonnefoi. -- Bonnefoi Pierre-Francois | E-mail : bonnefoi(a)unilim.fr Universite de Limoges, Laboratoire XLIM | Tel : 06 28 18 03 38 83, rue d'Isle | Mrs. Peel, we're needed... 87000 Limoges - FRANCE | The Avengers.

\placecontent bug
by Alan BRASLAU 03 Oct '10

03 Oct '10

Hans, Thank you for fixing the \placepublications argument issue bug. I confirm that the current beta now works correctly. I remind you of the \placecontents bug in a structured document. The attached minimal example illustrates the erroneous inclusion of appendix sections in the partial table of contents in the bodymatter chapters. (Chapter 1 toc also includes Appendix A sections, Chapter 2 toc also includes Appendix B sections, …) Alan

Verbatim: Pascal pretty printer
by Stefan Müller 02 Oct '10

02 Oct '10

Hi list, I wrote a custom pretty printer (verbatim) for Free Pascal/Turbo Pascal/Delphi source files. It's attached to this mail together with a ConTeXt test files that shows the features and some special cases. The pretty printer can handle: reserved words (bold) {...}-, (*...*)- and //...-style comments {$...} compiler directives '...' strings embedded assembler code (asm ... end) It's based on the Lazarus IDE syntax highlighter (Free Pascal IDE), which should be pretty Delphi-like. The main difference to Lazarus highlighting is that comments are not bold, but slanted. That looks much better when no colors are used. I'm not experienced in Lua programming, but I hope there are no major issues. I'd really appreciate any feedback: comments, suggestions and corrections (if necessary). I hope that eventually the Pascal pretty printer can make it's way into the ConTeXt distribution. Best wishes, Stefan. PS: Thanks for the Lua pretty printer, which served as a good starting point.

Re: [NTG-context] mixed English and Arabic using Simplefonts?
by Talal Al-Azem 02 Oct '10

02 Oct '10

Dear Wolfgang and Khaled, Thank you both for your replies. This has been very helpful. May I ask one further newbie question of simplefonts: how do I change the font for just the "fallback" font, without affecting the mainfont? Is there a way to do this by setting the size in points, or in scale (percentage), or some other fashion? In fontspec, i was accustomed to something like: \newfontfamily{\arfont}[Script=Arabic,Scale=1.66,WordSpace=1.66]{Scheherazade-Regular} I am sure there are equivalents for these feature (size, scale, wordspace); I've seen many features in the simplefonts pdf. But i'm unsure how to define something like "arfont" using simplefonts.

Simple Bibliography
by Elias Oltmanns 02 Oct '10

02 Oct '10

Hi there, in the attempt to stich together a simple bibliography, I don's seem to get as far as I'd have liked. The layout of the bibliography should look something like this: +----------------------------------------------+ | authora: title of book | | authorb, F.: opus magnum with a rather | | title and ref. details | | authord, authore: another important book | +----------------------------------------------+ To achieve this, I'm thinking of something along these lines: \definedescription[bibitem][ location=left,align=flushright,sample={ longest author},width=broad, command=\BibCommand] \def\BibCommand#1{#1:} \starttext \chapter{Bibliography} \bibitem{authora} title of book \bibitem{authorb, F.} opus magnum with a rather title and ref. details \bibitem{authord, authore} another important book \stoptext Alas, it doesn't work out as expected. Can someone give a few hints towards a working example? It should compile under MkII too. Thanks for your help, Elias

\structureheadnumber does not work before first section
by Vianney le Clément 02 Oct '10

02 Oct '10

Hi, I'm trying to get the last section number using \structureheadnumber[section][last]. This works fine inside a section, but expands to nothing when used at the beginning of the document. Here is a minimal example: \starttext Last: \structureheadnumber[section][last] \dorecurse{4} {\section{Test #1} Last: \structureheadnumber[section][last]} \stoptext Vianney
