ConTeXt and Blackletter fonts
by Reviczky, Adam 05 Jan '12

05 Jan '12

Hi list, I have problems typesetting various blackletter fonts with context (up to 2012.01.03 with luatex beta-0.70.1-2011051923 (rev 4277) using the suite). Here's an example (using oldengl.ttf[1]): --- \starttext \definedfont[file:oldengl*default] \input knuth \stoptext -- The resulting PDF (attached) has a wide space between each of the letters. Is this a problem with the font(s) itself or with context/luatex? (As a comparison I've tested these fonts with OpenOffice as well, and had no such issues.)

CLD: context.getvariable as Lua variable
by Wagner Macedo 05 Jan '12

05 Jan '12

Hello, I'm relatively quite new to TeX world. This is my first message to list. I hope you understand me, English isn't my mother language. I'm trying to use a variable set by \setvariable in Lua. I tried some combinations, based on manual but I couldn't succeed. The code below exemplifies what I wanted to do. \starttext \setvariable{namespace}{var}{Some context} \ctxlua{ local s = context.getvariable("namespace", "var") if s == "" then ... else ... end } \stoptext I know that I can use some of \if* TeX commands, but coding in Lua is better to me. -- Wagner Macedo

howto get good references in mkiv?

Hello Members, some piece of code, with the problems.

Not wanted hidden spaces when you compress fonts
by Jan Heinen 05 Jan '12

05 Jan '12

Hello, if I compress a font, there are suddenly hidden spaces between words. You can't see the spaces in the PDF, but when you copy the text from the PDF to an editor you can see the spaces. And when you search for a word (with hidden spaces) in the PDF, the word can't be found. This is the result when you copy the text from the PDF into an editor: "The quick brow n fox jum ps over the lazy dog." There is a space in "brow n" and one in "jum ps". When you search for "brown" in the PDF you get no result. Here is an example: \definefontfeature[cond][default][extend=0.8] \usemodule[simplefonts] \setmainfont[Allerlight][features=cond] \starttext The quick brown fox jumps over the lazy dog. \stoptext How to get rid of this hidden spaces?

xml file inclusion

I would like to include files with the following input xml-file <root> <file location=".." other_attributes</file> </root> In the xmlsetup for <file> I thought to place a call to \xmlinclude: \startxmlsetups xml:file \xmlinclude{#1}{.}{location} \stopxmlsetups But this does not work and I get the following error message: ! LuaTeX error ...-new/tex/texmf-context/tex/context/base/lxml-aux.lua:368: attempt to index field '__p__' (a nil value) stack traceback: ...-new/tex/texmf-context/tex/context/base/lxml-aux.lua:368: in function 'include' ...-new/tex/texmf-context/tex/context/base/lxml-aux.lua:393: in function 'include' ...-new/tex/texmf-context/tex/context/base/lxml-tex.lua:430: in function 'include' <main ctx instance>:1: in main chunk.

framedtext in itemize
by Hans van der Meer 04 Jan '12

04 Jan '12

Why does framedtext extends to the right in \itemize? Shouldn't the width be reduced by the extend of the item-shift? Isn't that the idea behind the "fit"-parameter. It wouldn't be a problem to calculate a reduced width, but how can I access the marginshift caused by the item? A minimal example: \starttext \startitemize[a] \item \startframedtext[offset=0pt,width=fit]\input tufte\stopframedtext \item \input tufte \stopitemize \startframedtext[offset=0pt,width=fit]\input tufte\stopframedtext \stoptext Hans van der Meer

SciTE configuration to use mkiv instead of mkii
by Peter Park Nelson 03 Jan '12

03 Jan '12

Hello, I installed and configured SciTE today to try it out. I am using the standalone distribution. When I try to process a context document with F7, SciTE calls texexec and uses mkii instead of mkiv (I always use mkiv/luatex). How do I configure SciTE to use mkiv?

mod_php vs context: tight loop
by Brendan Jurd 03 Jan '12

03 Jan '12

Hello list, I have a PHP application which generates documentation on the fly with context. This has been working really well, but I am now testing deployment on a new server with a more recent version of context, and it seems to be somehow getting itself into a tight loop. When I run texexec via the mod_php apache module, the command never returns, and `ps ax` shows the following: 9709 ? S 0:00 sh -c texexec --check 2>&1 9710 ? S 0:00 /bin/sh /usr/bin/texexec --check 9711 ? R 9:59 /usr/bin/texlua /usr/bin/mtxrun --usekpse --execute texexec --check `top` shows the mtxrun process eating 99.9% CPU. Attaching an strace to this process, once it is underway, shows no output. My test script is as follows: <?php $result = null; system("texexec --check 2>&1", $result); print $result . "\n"; ?> When this same test script is run directly from the command line with `php5 -f test.php`, it works as expected and outputs the following: MTXrun | kpse fallback with progname 'context' initialized in 0.01 secondsTeXExec | current distribution: web2c TeXExec | context source date: 2010.07.30 11:35 TeXExec | format path: . /root/.texmf-config/web2c/luatex /root/.texmf-var/web2c/luatex /root/texmf/web2c/luatex /etc/texmf/web2c/luatex /var/lib/texmf/web2c/luatex /usr/local/share/texmf/web2c/luatex /usr/share/texmf/web2c/luatex /usr/share/texmf-texlive/web2c/luatex /root/.texmf-config/web2c /root/.texmf-var/web2c /root/texmf/web2c /etc/texmf/web2c /var/lib/texmf/web2c /usr/local/share/texmf/web2c /usr/share/texmf/web2c /usr/share/texmf-texlive/web2c TeXExec | start of analysis TeXExec | end of analysis TeXExec | TeXExec | TeXExec | version 6.2.1 - 1997-2009 - PRAGMA ADE/POD 0 Using --timeout=30 in the arguments to texexec makes no difference; mtxrun nonetheless runs forever until it is signalled. It seems that this must be down to some kind of difference in Apache's execution environment -- I don't see any other way to explain the same PHP code working in cli and failing in mod_php, even when running as the same user. But what possible environmental factor could lead to mtxrun freaking out like this? I'm hoping someone on this list may be able to point me in the right direction. This server is a VZ instance running under proxmox, with the following relevant ubuntu packages installed (per the 'natty' release): context 2010.07.30-1 libapache2-mod-php5 5.3.5-1ubuntu7.3 apache2 2.2.17-1ubuntu1.4 -- Regards, Brendan Jurd Software Engineer Achieve, Corp brendan.jurd(a)achievecorp.com.au

(again) issues with streams
by Pablo Rodríguez 03 Jan '12

03 Jan '12

Hi there, playing with an example posted by Wolfgang to the list, I'm trying to generate a bilingual poetry edition (original and facing translation). If anyone could help, I'd really appreciate (this is the second time I post the message to the list http://www.ntg.nl/pipermail/ntg-context/2011/064184.html) This is a minimal sample: \enabletrackers[streams.flushing] \def\itit#1{{\language[it]\em#1}} \starttext \completecontent \startoutputstream[agr] \dorecurse{4}{\chapter{Knuth}\input knuth\par} \enableoutputstream[es] \dorecurse{4}{\chapter{Ward}\input ward\par \input tufte\par} \disableoutputstream \stopoutputstream \synchronizestreams[agr,es] \page \flushoutputstream[agr] \page \flushoutputstream[es] \stoptext My first question is how can I make that ConTeXt synchronizes automatically titles and paragraphs. I mean, I want to type the original first and the translation after the original and that ConTeXt typesets everything right (original with facing translation). My second question is how can I do that numbering on both sides is really independent. I mean that chapter and similar titles have the same number that its facing translations (and the same for footnotes). My third question is how can I number lines there, since I get the following error when using \starlinenumbering ... \stoplinenumbering (this is all Greek to me): !LuaTeX error: There should have been a lua <node> here, not an object with type nil! ==> Fatal error occurred, no output PDF file produced! Compilation failed. mtx-context | fatal error: return code: 70 Thanks for your help, Pablo -- http://www.ousia.tk
