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 Aditya, Here are the test result. > context.setvalue("lang", "English") It is working. > > > context([[\\def\\lang{English}]]) It is not working. It just prints "def langEnglish". Now, I got two solutions, using luacode and using \doifelse. Thank you. Best regards, Dalyoung

[supp-fil.mkiv] \openoutputfile & braces
by Philipp Gesang 29 May '11

29 May '11

Hi all, the mkiv definition of \openoutputfile adds undesired braces to filenames like “{out}.testfile2” and “{out.testfile3}”. ··8<····························································· \newwrite \testme %\openout \testme \jobname.testfile %%% works \openoutputfile \testme \jobname.testfile2 \openoutputfile \testme {\jobname.testfile3} \starttext irrelevant \stoptext ··8<····························································· mkii is fine. (Although I prefer plain \openout.) Philipp

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.

Validate (cross)references
by Andreas Schneider 27 May '11

27 May '11

Hello, if I use \in, \about, \at or anything else that generates a cross-reference, and that reference happens to be invalid (typo or whatever), it just prints out "nothing". Is there a way to have context throw an error if a reference is invalid? (That probably would only make sense in the second pass of context, since the first pass has to collect the references first.) If context can't do it by itself, I'll probably just grep for "unknown reference" and use that, but if context could do it by itself, it would be nice for automated builds (I actually have my current ConTeXt project in a Continous Integration system, so anything that leads to a wrong result should throw an error there.) -- Best Regards, Andreas

First Line After Whitespace Styling
by Marc Trius 27 May '11

27 May '11

Hi, I would like to be able to specify a style that would apply to text that appears on the first line of a paragraph after whitespace. I have no idea how to go about it. Specifically, I have a font with an alternate glyph that can only be used after whitespace, and I would like to have it used automatically when appropriate. Thank you, Marc Trius -- Marc Trius <derpayatz(a)riseup.net> "The enemy is the gramophone mind, whether or not one agrees with the record that is being played at the moment." --- George Orwell

Modifying the header of a Register : \setuphead or \setupregister not working
by Mathieu DUPONT 27 May '11

27 May '11

Hi, How can one modify the header of a Register, after it apparently inherited from Chapter ?In the following example, I try to have the title "INDEX" at the same height as the title "CHAPTER",but neither the \setuphead nor \setupregister commands seem to do anything.Is there another command for that ?I couldn't find it. Thanks for help ! \setupinteraction[state=start] \setuplabeltext[chapter=CHAPITRE~]\setuphead[chapter][ align=middle, before={\crlf\blank[1cm-4.2ex]}, style={\blank[2cm]}, after={\blank[3cm]}, header=empty, ] \defineregister[MyIndex][MyIndexs]\setupheadtext[MyIndex=INDEX] \setupregister[MyIndex][{\blank[0cm]}] %% not working\setuphead[register][{\blank[0cm]}] %% not working \starttext \startbodymatter\chapter{Chapter}\MyIndex{word}word\stopbodymatter \startbackmatter\completeMyIndex\stopbackmatter \stoptext Mathieu
