[NTG-Context] How to compute correct page number for handout
by Pierre-François Bonnefoi 03 Oct '10

03 Oct '10

Hello, I'use extensively context to write my lecture notes and for all of my printing needs. For my students, I've made some lecture presentations in color, and I print them in black&white, with four pages on one page for the handout. I would like to compute a correct Table of contents according to the handout : so to divide the current page number by four to get a correct page number for the handout. \def\ChapterPrefix#1{\the\numexpr#1/4 \relax} \setupcombinedlist[content][level=1] \setuplist[chapter][after=,before=,numbercolor=yellow,numbercommand=\underbar,pagecommand=\ChapterPrefix] That doesn't work, and I've some difficulties to figure how computation is performed in e-TeX... Could you help me to resolve this issue ? Kind regards, Pierre-François Bonnefoi. -- Bonnefoi Pierre-Francois | E-mail : bonnefoi(a)unilim.fr Universite de Limoges, Laboratoire XLIM | Tel : 06 28 18 03 38 83, rue d'Isle | Mrs. Peel, we're needed... 87000 Limoges - FRANCE | The Avengers.

Consolas
by Patrick Gundlach 01 Oct '10

01 Oct '10

Hi, several days ago I asked about companions to Cambria, and Wolfgang kindly gave me this: \definetypeface [mainface] [rm] [serif] [cambria] [default] \definetypeface [mainface] [ss] [sans] [corbel] [default] [rscale=auto] \definetypeface [mainface] [tt] [mono] [consolas] [default] [rscale=auto] \definetypeface [mainface] [mm] [math] [cambria] [default] which works fine, except for consolas. Shouldn't consolas be defined like \starttypescript [mono] [consolas] [name] \setups[\s!font:\s!fallback:\s!sans] \definefontsynonym [\s!Mono] [\s!file:consola] [\s!features=\s!default] \definefontsynonym [\s!MonoBold] [\s!file:consolab] [\s!features=\s!default] \definefontsynonym [\s!MonoItalic] [\s!file:consolai] [\s!features=\s!default] \definefontsynonym [\s!MonoBoldItalic] [\s!file:consolaz] [\s!features=\s!default] \stoptypescript instead of Sans.... ? It's much more a monospace font then a Sans. Thanks Patrick

Two layer in a document
by Daniel Grycman 01 Oct '10

01 Oct '10

Hi list, I am typesetting a template for internal documentation. In the header of the document I want to put two different figure. One on the left side and the other on the right side. When I compile the source the output shows only the figure on the left side. \enableregime[utf-8] \mainlanguage[de] \setupcolors [state=start] \setupoutput[pdftex] \setuppapersize[A4][A4] \usemodule [simplefonts,r,tikz,edtsnc,chart] \setmainfont [rubscalatz] \setsansfont [rubflama] \setuphead [chapter][number=no, style=bold, textcommand=\ss] \setuphead [section][number=no, style=bold, textcommand=\ss] \setuphead [subsection][number=no] \setuphead [subsubsection][number=no] \setuplayout [top=0cm,rightmargin=2.3cm,footer=1.0cm,header=5cm,topspace=0mm,height=29.9 577cm,width=16.25cm,leftmargindistance=0cm,rightmargindistance=0cm] \setupbackgrounds[footer][background=color,backgroundcolor=gray] \setupbackgrounds[text][rightmargin][background=color,backgroundcolor=gray] \setupbackgrounds[header][rightmargin][background=color,backgroundcolor=gra y] \definelayer[logo][width=\paperwidth,height=\paperheight,state=repeat] \setupbackgrounds[page][righttop][background={foreground,logo}] \setlayer[logo][preset=righttop,hoffset=1cm,state=start] {\externalfigure[label][height=4cm,3.5cm]} \definelayer[marke][width=6.5cm,height=0.3cm,state=repeat] \setupbackgrounds[page][lefttop][background={foreground,marke}] \setlayer[marke][preset=lefttop,hoffset=1.3cm,voffset=1.4cm,state=repeat] {\externalfigure[wortmarke][height=0.3cm,width=6.5cm]} \setuppagenumbering[state=stop] \starttext Bla Bla \page Bla Bla \page Bla \stoptext Can anybody find the possible mistake I did?

Computer Modern Unicode fonts
by Vladimir Lomov 01 Oct '10

01 Oct '10

Hi. I want to use Computer Modern Unicode fonts in my document. I made a link from $TEXLIVE2010/texmf-dist/fonts/opentype/public/cm-unicode to $CONTEXT_MINIMAL/tex/texmf-fonts/opentype/public but couldn't get CM-U font in the document. What should I do to use them? I'm using MkIV. --- WBR, Vladimir Lomov

font sizes (again)
by Florian Wobbe 01 Oct '10

01 Oct '10

Hi, please regard this minimal example: \setupbodyfont[10pt] \starttext \title{Title} \section{Section} {\switchtobodyfont[big] big} {\switchtobodyfont[small] small} {\tfxx tfxx} {\tfx tfx} {\tfa tfa} {\tfb tfb} {\tfc tfc} {\tfd tfd} \stoptext Latin Modern Regular is available in different optical sizes - lmroman{5,6,7,8,9,10,12,17}-regular.otf - and as context is aware of these sizes (configured in typescripts) I wonder why they are not correctly assigned. This table indicates what happens instead: \tfxx 6pt -> lmroman6 (as expected) \tfx 8pt -> lmroman8 (as expected) \tftf 10pt -> lmroman10 (as expected) \tfa 12.0pt -> lmroman10 (instead of lmroman12) \tfb 14.4pt -> lmroman10 (instead of lmroman12) \tfc 17.3pt -> lmroman10 (instead of lmroman17) \tfd 20.7pt -> lmroman10 (instead of lmroman17) \switchtobodyfont[small] 8pt -> lmroman8 (as expected) \switchtobodyfont[big] 12pt -> lmroman12 (as expected) \title 17.3pt -> lmroman10 (instead of lmroman17) \section 12pt -> lmroman10 (instead of lmroman12) The commands \title and \section and the font size switches \tfa, b, c, and d scale the font to the correct size, however, the wrong optical size is assigned. Note, this is not the case for \tfx, xx and \switchtobodyfont. Tested in MKIV and MKII (current beta). Is this a bug or a feature? Cheers Florian

Modules, namespaces, Luacode etc..
by Jaroslav Hajtmar 01 Oct '10

01 Oct '10

Hello my wise masters of the Force and teachers of Jedi... It seems that my first module (SCANCSV of scancsv.lua library of CTM in Brejlov) work without any visible errors (without documentation and with a junkyard yet), but I'm not sure whether is there a hidden problem or future collisions. Therefore I have a few of questions for modules namespaces, luacode namespaces etc. I want to ask how relates a namespace ConTeXt module with namespace of Lua code, which is listed within this module and others questions. 1. Is the namespace of Lua code independent of the namespace module? 2. If are ConTeXt macros defined in the module, are automatically in its namespace? 3. Can both namespaces (module and Luacode) somehow connected? 4. What happens when I have two macros with the same name in two different modules? 5. Can I call the macros of the same names in different namespaces (diferent modules)? 6. Can I read about somewhere more? 7. I enclose below a minimal example of the module (I do not know why there are some things) to comment or write yours comments and suggestions, etc. I'd like to start with something simpler, but this is the reality of our Empire.... Thanks everyone for the advice or recommendations for the study.

Lua & MP
by Procházka Lukáš Ing. - Pontex s. r. o. 30 Sep '10

30 Sep '10

Hello, is it possible that Lua gets value of a MetaPost variable? Let's have MetaPost code: z11=(0,0) z12=(1,1) z21=(0,1) z22=(1,0) aa[z11,z12]=bb[21,z22] So now aa = bb = 0.5. And I'd need to access MetaPost values 'aa' and 'bb' from Lua (e.g. in Lua: "local a = mpost.aa, b = mpost.bb"). Is it possible somehow? Regards, Lukas

composing characters in MKIV
by Mojca Miklavec 30 Sep '10

30 Sep '10

Dear Hans (or anyone else), There are some fonts (including Lucida) that don't have all the needed character. A font feature "compose=yes" has been added to MKIV, but that one doesn't work for Lucida or any other Type1 font. My current fallback is to use: % this doesn't help % \definefontfeature % [compose] % [liga=yes,kern=yes,tlig=yes,compose=yes] \beginNEWTEX \catcode`č=\active \catcode`Č=\active \defč{\buildtextaccent\textcaron c} \defČ{\buildtextaccent\textcaron C} \endNEWTEX But nevertheless a few questions: - Is there some "accessible" method to compose a few characters in the font (not too low-level) as opposed to using active characters? The code must be there already since this is supposed to work for OpenType fonts. - Is there any way to fix horizontal and vertical position of accents (on glyph-per-glyph basis; that one probably needs to be slightly more low-level; maybe using lfg files)? - Do lfg files work for non-opentype (Type1) fonts? Thanks a lot, Mojca

wrong sign or spacing in math/mkiv (at least in Lucida)
by Mojca Miklavec 30 Sep '10

30 Sep '10

Dear Hans, I'm not sure if the same problem would occur with other fonts as well (it is probably worth trying), but at least it happens with Lucida. Something is wrong with the spacing around the plus sign or maybe the wrong plus sign is taken (I suspect that). In MKII the formula is nicely aligned, while it looks ugly in MKIV. Here's the source: \beginOLDTEX \usetypescript[lucida][ec] \endOLDTEX \setupbodyfont[lucida] \starttext \startformula\startalign[align={left,left}] \NC m_{A_1'} \NC = (3+0+3+3+0+3) = 1 \NR \NC m_{A_2'} \NC = (3+0-3+3+0-3) = 0 \NR \NC m_{E'} \NC = (6+0+0+6+0+0) = 1 \NR \NC m_{A_1''} \NC = (3+0+3-3+0-3) = 0 \NR \NC m_{A_2''} \NC = (3+0-3-3+0+3) = 0 \NR \NC m_{E''} \NC = (6+0+0-6+0+0) = 0 \NR \stopalign\stopformula \stoptext Mojca
