Missing space between numbers in \showcolor (MkIV only)
by Vedran Miletić 26 Feb '11

\starttext \showcolor[rgb] \stoptext Numbers are next to each other. In MkII (with \setupcolors[state=start]) it looks OK. Regards. Vedran Miletić

how to make chapter starts from odd page always?
by Jeong Dalyoung 26 Feb '11

26 Feb '11

Dear all, I'd like to start every chapter starts from an odd page. page=right or page=left doesn't affect the page setting. I tried it using pagenumbering, but not succeed. I also want to put "counting" + pagenumber at the header of everypage. How to make it work? Here is my setting. Corrections for better shapes are welcomed. Thank you. Best regards, Dalyoung \definestructureconversionset[frontpart:pagenumber][][romannumerals] \definestructureconversionset[bodypart:pagenumber] [][numbers] \setupheadertexts[][{\tfx COUNTING}] \startstructureblockenvironment[frontpart] \setupuserpagenumber[numberconversion=romannumerals] \setuppagenumber[number=1] \setuphead[chapter][command=,number=no,page=right] \stopstructureblockenvironment \startstructureblockenvironment[bodypart] \setuppagenumber[number=1] \setuppagenumbering[alternative={singlesided,doublesided},location={header,left}]%singlesided,right] \setuphead[chapter][command=\Myheader, page=left] \stopstructureblockenvironment \startstructureblockenvironment[backpart] \setuphead[chapter][command=,number=no,page=left] \stopstructureblockenvironment

Please excuse my naive asking: Is there any way to continue using fontspec's setmainfont command (it is convenient for someone unexperienced like me) and at the same force luaotfload into using base mode? Thanks, - Till

Hyphenation patterns and adjusted kerning: ConTeXt vs. LuaTeX
by Heilmann, Till A. 25 Feb '11

25 Feb '11

Maybe the ConTeXt community can be of assistance to the LuaTeX bunch ... As a new LuaTeX user, I came across the following problem: Using Lua(La)TeX, customized kerning of letter pairs (via the FeatureFile capability of fontspec) is ignored when it coincides with a possible hyphenation of a word (e.g. between 'f' and 'h' in German words like 'aufhalten'; see first minimal example below). Ulrike Fischer was so kind to point out two things (http://tug.org/pipermail/luatex/2011-February/002569.html) First, the problem seems to be the break points between the adjusted kerning pairs. Second, ConTeXt seems to handle this case correctly (see second minimal example below; feature file bonum.fea from first example required). I am no expert in neither LuaTeX nor context, but Ulrike suggested I post here and ask if the (typographically correct) ConTeXt behavior or solution can be reproduced with Lua(La)TeX. Thanks, - Till 1. Lua(La)TeX \begin{filecontents*}{bonum.fea} languagesystem DFLT dflt; languagesystem latn dflt; feature kern { pos f h 100; } kern; \end{filecontents*} \documentclass{article} \usepackage[ngerman]{babel} \usepackage{fontspec} \setmainfont[FeatureFile=bonum.fea]{TeX Gyre Bonum} \begin{document} fh aufhalten \end{document} 2. ConTeXt \mainlanguage [de] \definefontfeature[test][featurefile=bonum,kern=yes] \definefont[test][name:texgyrebonum*test] \starttext \test fh aufhalten \stoptext

Thank you all, once again, for your help. It is much appreciated. (The downside: Now that I can, I have no choice but to actually fix all the terrible kerning mistakes in TeX Gyre Bonum. Hours and hours of work. Sigh...) - Till

post_linebreak_filter in context
by Patrick Gundlach 25 Feb '11

25 Feb '11

Hi, how do I install a custom post_linebreak_filter in ConTeXt? I have this LaTeX file: ------------------------------------------------------------------------------------ \documentclass[12pt,a4paper]{scrartcl} \usepackage[english]{babel} \usepackage{blindtext} \usepackage{fontspec} \directlua{ show_hyph = function(head) while head do if head.id == 0 or head.id == 1 then % hlist, vlist show_hyph(head.list) % should be head.head in a newer luatex than 0.64 elseif head.id == 7 then % disc local n = node.new("whatsit","pdf_literal") n.mode = 0 n.data = "q 0.3 w 0 2 m 0 7 l S Q" n.next = head.next n.prev = head head.next = n head = n end head = head.next end return true end luatexbase.add_to_callback("post_linebreak_filter",show_hyph,"show_hyph") } \begin{document} \begin{minipage}{5cm} \blindtext \end{minipage} \end{document} ------------------------------------------------------------------------------------ which registers a function "show_hyph" as the post_linebreak_filter (the rest is not really interesting). How would I do this in ConTeXt? (also asked on tex.se: http://tex.stackexchange.com/questions/11960/how-to-register-a-callback-in-…) Thanks Patrick

Float option “top” affects page break (on following pages)
by Andreas Harder 25 Feb '11

25 Feb '11

Hi all, consider the following example. \starttext \showgrid Try to comment the \tex{placefigure} command, there will be 40 lines on the second page. If you uncomment it again there are 41 lines! \placefigure[top,nonumber]{}{\externalfigure[dummy]} \page \dorecurse{30}{line \recurselevel\par} \blank[medium,small] \dostepwiserecurse{31}{50}{1}{line \recurselevel\par} \stoptext It's really a problem if compiling a component file which ends up with another page breaking than the corresponding product file. I hope there will be soon a fix for that … is there already one? Regards Andreas

btex and DeclareGraphicsRule question
by Rebecca Searls 25 Feb '11

Why does stmt, label(btex Au dessus etex, (0,0)); fail when using stmt, \DeclareGraphicsRule{*}{mps}{*}{} but works with stmt, \DeclareGraphicsRule{*}{eps}{*}{} I am running texlive/2010. Here is the error msg I get when using mps. >/usr/local/texlive/2010/bin/i386-linux/mpost xtest.mp This is MetaPost, version 1.211 (TeX Live 2010) (kpathsea version 6.0.0) (./xtest.mpfatal: Command failed: etex --parse-first-line --interaction=nonstopmode mpIYqrrH.tex; see mpxerr.log >> xtest.mp >> xtest.mpx !

I don't understand what in xstyle.sty can be having an affect on \DeclareGraphicsRule{*}{mps}{*}{}. Can anyone provide any helpful information? My preference is to use mps and not eps.
