Unwanted change of paper size; extra opt for \externalfigure
by Procházka Lukáš Ing. - Pontex s. r. o. 10 Jun '11

10 Jun '11

Hello, see the following example: ---- \starttext AAA \startTEXpage \rotate[rotation=-90]{\externalfigure[Model.pdf]} \stopTEXpage % Paper size is 297 * 297 mm from now?! BBB \stoptext ---- Why the last paper size becomes 297 x 297 mm? Suggestion: Wouldn't be good to have an option "rotation" (among "scale", "factor", width"...) to rotate the inserted figure, at least in multiples of 90 degrees? To allow something like: \externalfigure[Model.pdf][width=180mm,rotation=-90] Best regards, Lukas (ConTeXt ver: 2011.05.18 18:04 MKIV fmt: 2011.5.18, WinXP) -- Ing.

What I get you can see in the by the list administrator released mail from yesterday. I am stymied. Willi

Getting arguments by Lua
by Procházka Lukáš Ing. - Pontex s. r. o. 09 Jun '11

09 Jun '11

Hello, when I run context by e.g.: context.exe Source.mkiv --result=Result.pdf --mode=Mode is it possible to access the command line arguments from Lua? I'm aware that modes are accessible by 'tex.modes' ('tex.modes.Mode' gives 'true' in this case); but I'd need to get also the source file name ("Source.mkiv") and the option ("--result" -> "Result.pdf"). Is it possible anyhow? Best regards, Lukas -- Ing. Lukáš Procházka [mailto:LPr@pontex.cz] Pontex s. r. o.

But it seem have no efforts as before, because I could not find the font adobesongstd use command mtxrun --script fonts --list --pattern=* --all. But I can see the font use system fc-list command, What's the problem and how can I fix it. Thanks.

Random selection of a word in a set with lua and mkiv
by Otared Kavian 08 Jun '11

08 Jun '11

Hi all, Assuming that we have a set of words or expressions, say {Maths, Physics, Algebra, Analysis, Chemistry, Geometry, Wave equation, Schrödinger equation} is it possible to write a lua function, named for instance randomselectword which returns one of the words or expressions selected at random in the above set? Indeed this is intended to be used in a TeX file processed with mkiv. Thanks in advance for any idea and help. Best regards: OK

Context.exe and --result=...
by Procházka Lukáš Ing. - Pontex s. r. o. 08 Jun '11

08 Jun '11

Hello, I have the following situation. One source file is to be converted by Ctx normally and secondly with a special mode, e.g. "--mode=PageOneOnly". I'd like to get two result with: (1) Context.exe source.mkiv -> should give 'Source.pdf', (2) Context.exe source.mkiv --mode=PageOneOnly --result=Source-Pg1.pdf -> to give 'Source-Pg1.pdf'. The problem is that the option "--result=..." just renames the result; it means, if the 'Source.pdf' has been created by (1), it would be OVERWRITTEN by (2), as (2) normally processes 'source.mkiv' to 'source.pdf' in the first phase and renames it after. So the question is - is there a better way which would PRESERVE the <file>.pdf if <file>.mkiv is to be processed and '--result=<another-file>' is being used? Or (question for developers) - wouldn't be better to work directly with an output stream(s) name based on '--result=...' option, and to take the source file name for the output stream name ONLY in case that '--result=...' was not specified? (This would also mean to create other support file(s), like 'Source-Pg1.log', 'Source-Pg1.tuc' - IMHO this would be OK.) Best regards, Lukas -- Ing.

math in antp with MKIV

08 Jun '11

Hello, I'm trying to use \usetypescript[antykwa-poltawskiego] \setupbodyfont[antykwa-poltawskiego,10pt] \starttext \eTeX \stoptext but it fails miserably. An easy workaround is to use greek letters, but also the whole math is somewhat broken. In MKII the font would fall back on Latin Modern in case that there are no math glyphs, but ConTeXt MKIV complains about ! Math error: parameter \Umathquad\displaystyle is not set. system > tex > error on line 6 in file a.tex: Math error: parameter \Umathquad\displaystyle is not set ... What would be the remedy for that?

DocBook in ConTeXt - any new ideas?
by Piotr Kopszak 05 Jun '11

05 Jun '11

Dear list, I am beginning a rather tedious documentation project and will most probably end up with DocBook. The fact is I haven't used it for any serious work for about 10 years. Docbook In ConText haven't been updated since 2003. Does it mean it's so perfect or instead rather obsolete? Could you recommend other approaches which work out-of-the-box (or almost). Obviously I would prefer ConTeXt based solutions. DocBook is not mandatory in fact, I would happily learn other documentation system. Main prerequisite is utf-8 output at least in pdf and html and sensible defaults (this time I don't want to be a typographer, nor I want to fiddle with structure). Best Piotr -- http://okle.pl

xml syntax for \externalfigure

Hi all, I'm pulling my hair - thought this was easy, but turns out to be more difficult.

Here's a minimal example that I can't make work. If anyone can explain what to do here, I might be able to work this out (or will be back with more questions :-) \startbuffer[test] <a> <externalfigure height="1cm" resource="hacker"/> </a> \stopbuffer \startxmlsetups xml:testsetups \xmlsetsetup{\xmldocument}{a|externalfigure}{xml:*} \stopxmlsetups \xmlregistersetup{xml:testsetups} \startxmlsetups xml:a \xmlflush{#1}\par \stopxmlsetups \startxmlsetups xml:externalfigure \externalfigure[\xmlatt{#1}{resource}] [\doifnotempty{\xmlatt{#1}{height}}{height=\xmlatt{#1}{height}}] \stopxmlsetups \starttext \xmlprocessbuffer{main}{test}{} \stoptext The "height" attribute is not taken into account - why?

teletype style in type-win.mkiv

Hello all, I'm afraid I've never spent the time to understand fonts properly, I just make do with the defaults most of the time. Now, however, I am being forced to use company default fonts for some documents. I have got as far as using the following commands to setup my body font: \usetypescriptfile[type-win] \usetypescript[arial] \setupbodyfont[arial, 10pt] But the teletype style now has no effect: e.g. using {\tt teletype} gives the same font as normal, and \showbodyfont reveals the same. I've tried making sense of the type-win.mkiv file but it's beyond me! Any suggestions how to get \tt to use Courier New, for instance? Thanks, Richard Converteam UK Ltd.

However, it is a good oppertunity to know various methods and lua codes. I didn't know that \labeltext can do the same thing. Your sample gives me a new ideas to handle them. Thank you so much. Best regards, Dalyoung

ctx conference 2011
by Hans Hagen 01 Jun '11

01 Jun '11

Hi, Taco and I are discussing the program of the upcoming context conference. So far we've come up with the following categories: - graphics: metapost tricks, metapost decimal / scientific numbers, basic graphs (maybe I'll upgrade the graph package to the new mp machinery), graphic conversion, gnuplot, pdf standards, etc - math (and science related) things: fonts, unicode, structured math (input and export) - accessibility: like registers (and sorting them), structure, epub production, styling, coding etc, interactivity (maybe widgets etc) - user experiences and tutorials: this can be anything If there are special demands we can try to fulfill them, so feel free to contact us. Proposals for talks are welcome, Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

[register] setup detailed formatting

Hi all, according to the manual (current draft p. 238f.) the following should work: ···8<···························································· \setupinteraction[state=start] \defineregister[myreg][myreg] \setupregister[myreg][textstyle=italic,pagestyle=slanted] %% That’s what it’s about: \setupregister[myreg][alt][textstyle=bold] \starttext \myreg{one}one \myreg{two}two \myreg{three}three %% This works in mkii but not mkiv. \myreg[alt::two]{two}two \myreg[alt::zwo]{two}two \myreg[alt::zwo]{alt::two}two \myreg{alt::two}two \myreg{one}one \placemyreg \stoptext ···8<···························································· (mtx-context | current version: 2011.05.12 15:19 This is LuaTeX, Version beta-0.71.0-2011060119 (rev 4285)) Mkii is fine but I seem to need this functionality in mkiv for local font switches (when entries are in a different script). Am I using this right? Any known workaround? Thanks for your help Philipp

unusual behaviour of \if(x)
by Mojca Miklavec 01 Jun '11

01 Jun '11

Dear magitians, I discovered this in LaTeX, but ConTeXt behaves the same (plain TeX behaves differently). Can somebody please explain me why this code fails to work? (A workaround is to move \newif on top which I'm willing to do, but I'm still curious.) \starttext \ifx\hbox\undefined \message{invisible to tex} \newif\ifabc \abcfalse \ifabc \message{abc true breaks} \else \message{abc false breaks} \fi \fi \stoptext systems : begin file iftest at line 1 abc false breaks !

Moving module installation from first-setup.sh to ctxtools
by Bruce 01 Jun '11

01 Jun '11

Per subject line, I'd just like to suggest moving the (quite helpful) module installation functionality from first-update.sh to one of the core context scripts (like ctxtools), so that it's usable outside the minimal distribution (in TL). E.g. something like: ctxtools --install="t-simpleslides" Bruce

newbie questions
by Sanja C. 31 May '11

31 May '11

Hi ConTeXt community. While looking for free (preferably open-source) tools which I could use for typesetting a planned internal newsletter-booklet for a non-profit organization (to be released in printed form in regular intervals - each issue with new content of course, but same/similar style), I came across ConTeXt. I usually use Inkscape and various WYSIWYG word processing software for designing and layouting flyers/leaflets/etc., but in this case (many pages, varying and regularly updated content, consistent style) I'm afraid those tools simply don't cut in in terms of professional-quality typesetting capabilities and content//style separation. So programmatic typesetting might be the answer. I thought of LaTeX first, but I read from various sources that using ConTeXt might be easier for typesetting book-like things, especially if you want to design your own styles. Before I delve in deeper, though, I would like to ask you (the ConTeXt community) some questions: a) Is the ConTeXt project alive? The newest PDF documentation I could find seems to be from 2007; most of it is dated 2003 or older. b) Do you think that ConTeXt is an appropriate tool for the use case I described (be honest please ;-)), and easy enough to learn for someone with almost no TeX experience? The requirements are: - Support for elaborate, colorful, graphics-heavy design, which I would preferably create in Inkscape and then export as vector graphics (or port to ConTeXt's own graphics language) as necessary. - Ability to write a style *once* (with reasonable effort), and "outsource" it to an external file (or files), so that for each new release of the newsletter, only a simple content TeX file (or files) with minimal amount of markup is required (which e.g. even a non-tech-savvy writer/editor could edit) - Ability to easily include pictures in the content, and let the typesetting engine automatically position them (either in the main text area with text floating around them, or in special margin areas). c) Are there any full-featured examples of design-heavy booklets/magazines/etc created with ConTeXt., for which the full source code is publicly available? That would be *really* helpful in order to assess how much work would be required, and also to learn how exactly it's done in practice. Thanks! Sanja C.

a tiny set of documents for introduction to ConTeXt (for MacTeX)
by Mojca Miklavec 31 May '11

31 May '11

Hello, In the preparation for TL 2011 Richard Koch asked about the following: > We install some documentation about > ConTeXt, LuaTeX, and XeTeX in /Applications/TeX, mainly > for people who only know LaTeX but would like to get a feel > for later developments. That documentation needs to be up to > date. At the moment there is the following document in there: The language mix Abstract During the third ConTEXt conference that ran in parallel to EuroTEX 2009 in The Hague we had several sessions where mkiv was discussed and a few upcoming features were demonstrated. The next sections summarize some of that. It's hard to predict the future, especially because new possibilities show up once LuaTEX is opened up more, so remarks about the future are not definitive. One document for XeTeX contains two paragraphs, demonstrating usage of Arabic, Hebrew and Japanese: \newfontfamily{\A}{Geeza Pro} \newfontfamily{\H}[Scale=0.9]{Lucida Grande} \newfontfamily{\J}[Scale=0.85]{Osaka} Here are some multilingual Unicode fonts: this is Arabic text: {\A السلام عليكم}, this is Hebrew: {\H שלום}, and here's some Japanese: {\J 今日は}. The idea is to have a simple, yet powerful example showing some capabilities of ConTeXt, together with source code. I find this important for promotion of ConTeXt to new users. The question is: does anyone have any good ideas what to put there? Mojca

Dear Pontus, Marco, and Peter, Thank you for replies. I tested the following codes: 1) \startluacode if languages.current() == "kr" then context("Korean") else context("Not Korean") end \stopluacode 2) \doifelse\currentlanguage{en}{\def\lang{English}}{\def\lang{Not English}}\par currentlanguage: \lang are working well. But, the code \startluacode if languages.current() == "kr" then context([[\def\lang{Korean}]]) %("\def\lang{Korean}") else context([[\def\lang{English}]]) %("\def\lang{Korean}") end \stopluacode currentlanguage: \lang is not working. (undifined control sequence error) I think that there is a simple way to use lua code for this which I don't know. I have to read CLD manual. Thanks again.
