\environment before vs. after \startproduct
by Andreas Harder 16 Jul '11

16 Jul '11

Hi, here is another problem regarding \environments. % \setupbodyfont[palatino] % OK \starttext \setupbodyfont[palatino] % not OK \startformula \binom{n}{0} \stopformula \stoptext To avoid it, I'd have to use something like the following? \environment font-setups \startproduct \environment blank-setups Greeting Andreas

Re: [NTG-context] UTF8 / TeXUtils parsing error
by Brian Wedde 15 Jul '11

15 Jul '11

I updated Ruby to the latest and greatest beta but have the same results: TeXUtils does not function correctly when processing .tui files, likely due to character encoding issues in Ruby. I'm running Ruby 1.9.2 and this seems to be the problem. 1.8.7 was working fine on other machines. There are evidently large changes in Ruby API and string handling and character encoding in upgrading from 1.8.x -> 1.9.x. I'm making the assumption that the only way to handle this is to downgrade Ruby. Are there any alternatives? Thanks for your help again!

Trouble making basic MetaPost graphics using ConTeXt Minimals
by Kevin D. Robbins 15 Jul '11

15 Jul '11

Using a fresh install of ConTeXt Minimals today (ConTeXt version 2011.07.14 16:09, luatex version beta-0.70.1-2011051918) I am trying to build the following MetaPost graphics: ---8<--- file: test.mp fontmapfile "=lm-math.map" ; beginfig(1) draw fullcircle scaled 3cm ; endfig ; beginfig(2) ; fill fullcircle scaled 5cm withcolor red ; endfig ; beginfig(3); numeric u; u = 1cm; draw (0,2u)--(0,0)--(4u,0); pickup pencircle scaled 1pt; draw (0,0){up} for i=1 upto 8: ..(i/2,sqrt(i/2))*u endfor; label.lrt(btex $\sqrt x$ etex, (3,sqrt 3)*u); label.bot(btex $x$ etex, (2u,0)); label.lft(btex $y$ etex, (0,u)); endfig; end . ---8<--- Building the file using "mpost test.mp" I get the following: This is MetaPost, version 1.504 (kpathsea version 6.0.0) (mpost.mp (/opt/tools/ConTeXt/beta/tex/texmf/metapost/base/plain.mp Preloading the plain mem file, version 1.004)) (./test.mp{pdftex.map}{lm-math.map} [1] [2]/opt/tools/ConTeXt/beta/tex/texmf-context/scripts/context/ruby/base/switch.rb:570:in `locateseries': undefined method `each' for "tex":String (NoMethodError) from /opt/tools/ConTeXt/beta/tex/texmf-context/scripts/context/ruby/base/switch.rb:397:in `block in expand' from /opt/tools/ConTeXt/beta/tex/texmf-context/scripts/context/ruby/base/switch.rb:392:in `each' from /opt/tools/ConTeXt/beta/tex/texmf-context/scripts/context/ruby/base/switch.rb:392:in `expand' from /opt/tools/ConTeXt/beta/tex/texmf-context/scripts/context/ruby/texexec.rb:789:in `<main>' >> test.mp >> test.mpx ! Unable to make mpx file. l.18 label.lrt(btex $\sqrt x$ etex, (3,sqrt 3)*u); 2 output files written: test.1 .. test.2 The first two graphics are produced correctly, but there is no output for the third graphic with the labels. Building the file using "texexec --mptex test.mp" all three graphics are produced, but the label $\sqrt x$ does not produce the square root symbol. Am I doing something obviously wrong? Can anyone reproduce this? Thanks, Kevin

n-dash and line break
by Thomas A. Schmitz 15 Jul '11

15 Jul '11

Hi all, is this the intended behavior? In mkiv, no line break after an n-dash; in mkii only if it is keyed in as "--", not directly as the utf char. I think lines should be broken at n-dashes. All best Thomas (hope the example isn't maimed by my mail agent) \setuplayout[width=5cm] \enableregime[utf] \showframe \starttext 0--1--2--3--4--5--6--7--8--9--0--0--1--2--3 0–1–2–3–4–5–6–7–8–9–0–0–1–2–3 \stoptext

Normally it should sync itself so there must be some interference somewhere.

From \chapter to \startchapter \stopchapter
by Cecil Westerhof 15 Jul '11

15 Jul '11

Instead of only pdf I also need to generate XHTML. For this I need to use \startchapter and \stopchapter instead of \chapter. When it is like: \chapter{A descriptive title} I have to change it to: \startchapter[title=A descriptive title] . . . \stopchapter But how do I change something like: \chapter[aboutLink]{A descriptive title} -- Cecil Westerhof

File.export to File.html
by Procházka Lukáš Ing. - Pontex s. r. o. 15 Jul '11

15 Jul '11

Hello, the following question may relate to XML processing rather to Context. But someone may have needed to solve the problem. Lets have a File.export which was generated by Context with "\setupbackend[export=yes,xhtml=yes,css=yes]". Such a XML output file uses tags like: <section> <sectionnumber> <sectiontitle> <sectioncontent> <itemgroup> <item> ... Has anyone solved conversion of such a file to an [arbitrary] .(x)html? I have only slight knowledge about XML transformations - the task is just about converting the Context XML to XHTML - and I would be hardly able to write a XSLT from scratch. Moreover, I don't have personal experience with any XML processor/converter. It wouldn't be so important how the resulting .html would be "perfect"; the main goal is to convert Context File.export to File.html with working hyperlinks to view it in a web page viewer. Could anyone describe his experience? - Processor, support file(s) (XSLT?); any demos of such support files (their "minimals") or "complex solutions" would be welcome; whatever working solution. I'm WinXP (32b) user, so demos for Windows are preferred but any hints are welcome. Kind regards, Lukas -- Ing. Lukáš Procházka [mailto:LPr@pontex.cz] Pontex s. r. o.

bib module (again)
by Steffen Wolfrum 15 Jul '11

15 Jul '11

Hi, I have a basic problem with the very first step of using bibliographies in ConTeXt: converting BBI to BBL files. And, as far as I have understood, the only thing that ".bst" files do is sorting. This means that a plain run of bibtex like this ... \setupbibtex[database=mytry_x.bib] \starttext Test \completepublications \stoptext ... should convert the entire database (eg. from a ".bib" file) in TeX-parsable records, written in a ".bbl" file. If I want to shorten many authors to just one followed by "et al." there is the otion "authoretallimit" that specifies the number needed to trigger 'et al.' handling. This can be set *later* in setuppublicationlist. But when I run the minimal exmaple above against this database "mytry_x.bib": @BOOK{daunerliebkonzenschmidt, author = {Peter Schlechtriem and Horst Konzen}, } @BOOK{schlechtriemschmidtkessel, author = {Peter Schlechtriem and Horst Konzen and Karsten Schmidt}, } ... the resulting bbl lookes like this: \setuppublicationlist[samplesize={SKS},totalnumber=2] \startpublication[k=daunerliebkonzenschmidt,t=book, a={{Schlechtriem},{Konzen}},y=, n=1,s=SK] \author[]{Peter}[P.]{}{Schlechtriem} \author[]{Horst}[H.]{}{Konzen} \stoppublication \startpublication[k=schlechtriemschmidtkessel,t=book, a={{Schlechtriem},{}},y=, n=2,s=SKS] \author[]{Peter}[P.]{}{Schlechtriem} \author[]{Horst}[H.]{}{Konzen} \author[]{Karsten}[K.]{}{Schmidt} \stoppublication So the three authors *are* already shortened to "a={{Schlechtriem},{}}" only! Is this a bug or a hidden preset that I just didn't found yet? Any help would be appreciated Steffen

UTF8 / TeXUtils parsing error

The culprit is "\enableregime[utf]". It works fine with TeXLive2010 on Linux, but not on a ConTeXt Minimals (stable) installation on FreeBSD. I'm assuming I haven't installed something correctly. \contextversion outputs "2010.07.30 11:35" Any thoughts? This one is over my head. Thanks! Your help is very much appreciated
