mkiv: bug in processMPbuffer
by Otared Kavian 24 Oct '08

24 Oct '08

Hi Hans and Taco, The latest beta solves the problems metioned by Thomas Schmitz and myself concerning \uniqueMPgraphic: many thanks for your attention. However, I observed the following regarding \processMPbuffer: some grahpics don't show up when tyepset with mkiv, while they are fine with mkii. (This with mkiv, LuaTeX revision 2, (LuaTeX date stamp 2008102016), ConTeXt version 2008.10.23 17:32). (For the Chief of Rumour Control: it is not crucial to address the reported bug urgently…).

new beta
by Hans Hagen 24 Oct '08

24 Oct '08

Hi, this time a beta that is more beta than usual (mkiv) - it needs a recent luatex (no surprise) - there are some speedups, but it might break things (should not happen) - the memory footprint should be a bit smaller (esp fonts) - font fallbacks etc have some fixes a major change is that now all multipass data goes into the jobname.tuc file (only lists are still in the tuo file); a next release will have sectioning redone and for mkiv the tuo file will be gone Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

Some questions about TeX Gyre support in minimals
by Oleg Kolosov 24 Oct '08

24 Oct '08

Hello Everyone! I've started to experiment with MkIV in ConTeXt minimals recently trying to make TeX Gyre fonts work with as few definitions as possible. Here is the list of problems I've encountered: 1. No small-caps in any font (gyre fonts doesn't have that yet?) 2. adventor have italic but slanted displays as normal (roman) 3. cursor have only roman script (no bold, slanted, etc.) Is this due to lack of fonts in Gyre package, some omissions in type-otf.tex or my typescript definitions are not complete? Here is the test file which I've used (some cyrillic text also): ------------------------ \starttypescript[mygyre] % change font last arg according to definitions in type-otf.tex % pagella, termes, bonum, schola \definetypeface [mygyre] [rm] [serif] [pagella] % heros, adventor \definetypeface [mygyre] [ss] [sans] [adventor] \definetypeface [mygyre] [tt] [sans] [cursor] \definetypeface [mygyre] [mm] [math] [palatino] \stoptypescript \startbuffer[tests] \starttabulate \NC \tf tf \NC \tf Нормальный текст \NC\AR \NC \bf bf \NC \bf Полужирный текст \NC\AR \NC \it it \NC \it Курсивный текст \NC\AR \NC \sl sl \NC \sl Наклонный текст \NC\AR \NC \bi bi \NC \bi Полужирный курсив \NC\AR \NC \bs bs \NC \bs Полужирынй наклонный \NC\AR \NC \sc sc \NC \sc Пробный текст \NC\AR \stoptabulate \stopbuffer \usetypescript[mygyre] \setupbodyfont[mygyre] \starttext \section{roman (rm)} {\rm \getbuffer[tests]} \section{sans-serif (ss)} {\ss \getbuffer[tests]} \section{teletype (tt)} {\tt \getbuffer[tests]} \stoptext ------------------------ I'll update Russian section in the wiki, once these points are clarified. -- Regards, Oleg Kolosov

Invalid UTF-8 sequence in bbl file
by Oleg Kolosov 23 Oct '08

23 Oct '08

Hi all, Taco! I was experimenting with bib module and discovered something which looks like a bug. 'texexec' ('texexec bibtest') runs fine but typesets references ('s' key) incorrectly. As MkIV does not run bibtex on input files automatically, I run 'bibtex' manually once ('bibtex bibtest'), then 'context' ('context bibtest') gives 'Invalid UTF-8 sequence' error. The resulting .bbl is the same in both cases. It seems that 'author' field and 's' key in bbl file are generated incorrectly, while others like 'title', 'city', etc. are fine. See the attached files. I'm using just updated minimals. t-bib version 2008.04.17. -- Regards, Oleg Kolosov \setuppublicationlist[samplesize={ÐÐ02},totalnumber=1] \startpublication[k=parintro,t=book, a={{ÐÐœÑÐŸÐœÐŸÐ²}},y=2002, n=1,s=ÐÐ02] \author[]{Ð.~Ð¡.}[Ð.~Ð.]{}{ÐÐœÑÐŸÐœÐŸÐ²} \pubyear{2002} \title{ÐÐ²ÐµÐŽÐµÐœÐžÐµ Ð² Ð¿Ð°ÑÐ°Ð»Ð»ÐµÐ»ÑÐœÑÐµ Ð²ÑÑÐžÑÐ»ÐµÐœÐžÑ} \city{ÐÐŸÑÐºÐ²Ð°} \pubname{ÐÐÐ£ ÐžÐŒ.

Re: [NTG-context] PhD Thesis in ConTeXt
by Piotr 23 Oct '08

23 Oct '08

Hello, thank You (!) for the many responses - I am surprised about how many people answered with suggestions, opinions, useful information and templates. I think I will give context a try - if it will run on my Vista-64 System. I will check that out in the next day(s). It sounds as a good alternative to Latex if it is really superior when it comes to image inclusion with descriptive text. Jeff, would it be allright for You to publish the source of Your very useful python Endnote-Bibtex conversion program? Marcin, it seems the link to the polish article is defunct. But the summary was very good, thanks for it :) Regards,

Hi everyone, Sorry for posting this message again: I am not sure it went through… The following doesn't show the "swelled rule" defined below in mkiv, while on mkii it is fine?

project structure simplification ?
by Steffen Wolfrum 23 Oct '08

23 Oct '08

Hi, when there is only one product, only one environment-style (but lots of component) in a project, is it necessary to start the files with these respective lines ... \startproject the_project \startproduct the_product \startenvironment the_style ... or is it sufficient for referencing to call only the file the_project.tex, the_product, the_style ? [asking for both, MkII and MkIV] Steffen

picture before \chapter breaking \header \footer setup
by Jelle Huisman 23 Oct '08

23 Oct '08

Hi all, Another question, this time about \headers and \footers. On the first page of the chapter I have the page number in the footer and on all other pages they are in the header. This works fine, as expected. However I have to include an \externalfigure *before* the \chapter command and I discovered that I have to use \startcombination because otherwise the \chapter moves to the next page. However, when I use \startcombination ... etc \chapter is not longer the first thing on the page and the special header/footer setup is not triggered (apparently \chapter has to come first for that to happen). See sample code: % sample \definetext[mychapter][footer][pagenumber] \setuphead[chapter][header=high,footer=mychapter] \showframe \starttext %\startcombination[1*1]{\externalfigure}{ % uncomment to see problem \chapter{first} %}\stopcombination % uncomment to see problem \dorecurse{20}{\input tufte \relax} \chapter{second} \dorecurse{20}{\input tufte \relax} % this works as expected \stoptext % sample Is it possible to make this work? (maybe an extra \chapter command before the combination that triggers the header-footer setup, but that is not printed after all?) Thanks for any help. Jelle
