Heading with linebreaks in pdf bookmarks: linebreak sign stays
by Peter Schorsch 17 Jul '11

17 Jul '11

Hi, as soon I have a linebreak inside a heading via \\ I get this \\ also in the text of that heading in the pdf-bookmarks: \setupinteraction[state=start] \placebookmarks[chapter,section,subsection][chapter,section] \starttext \completecontent[criterium=all] \chapter{A very,\\very long long title} \chapter{A very, very long long title} \stoptext What did I forgot to get rid of the linebreak sign in the pdf bookmarks?

Re: [NTG-context] about suppressing prefix in section number

Dear Wolfgang, > \setupitemgroup[ltxitm][3][circlednumber,packed][stopper=] It is working. It depends on the fonts. Also, \def\circlednum#1{\uchar{36}{95+#1}} \defineconversion[cnum][\circlednum] \defineitemgroup[txitm][levels=5] % \setupitemgroup[txitm][1][R] \setupitemgroup[txitm][2][a] \setupitemgroup[txitm][3][cnum,packed][stopper=] is working too. Thank you so much. Best regards, Dalyoung

Finding values of the context macros inside Lua functions (=expansion inside Lua functions?)
by Jaroslav Hajtmar 17 Jul '11

17 Jul '11

Hello all, For several hours trying to find solutions of problem. My minimal example (I mention it at the end of email) for clear reasons show, that : 7 is not number. 7 is number. 7is not number. 7is not number. In the first is argument '\value' negotiable to the value, in second it is not possible (but for clear reasons too). I would need to find from argument ie macro '\\value' in the LUA function its numerical value. Is there any function that would do that? I need something as a function of context (...), which would, however, its output is not located into ConTeXt, but its result get to back to a Lua function or into variable. It is something like the expansion of an existing ConTeXt macro to its value. Thanx Jaroslav Here is my minimal example: \startluacode function test(arg) if type(arg)=='number' then context(arg.." is number.\\par ") else context(arg.." is not number.\\par") end if type(tonumber(arg))=='number' then context(arg.." is number.\\par ") else context(arg.." is not number.\\par") end end \stopluacode \starttext \def\value{7} \ctxlua{test('\value');} \blank[big] \ctxlua{test('\\value');} \stoptext

Dear Wolfgang, Thank you for the solutions. But for the question 2, I didn't explain well what I want to. Actually, the codes >> >> \def\circlednum#1{\uchar{36}{95+#1}} >> \defineconversion[cnum][\circlednum] > working well by saying that \startitemize[cnum][stopper=] ... And, your suggested method works well, too. My question is that is it able to define new itemize header, for example, circled number using \defineitemgroup so that I got circled number in the 3rd level automatically without saying that \startitemize[cnum]. In the wiki, \defineitemgroup[ltxitm][levels=5] % \setupitemgroup[ltxitm][1][1] \setupitemgroup[ltxitm][2][2] \setupitemgroup[ltxitm][3][3,packed] \setupitemgroup[ltxitm][4][4,packed] \setupitemgroup[ltxitm][5][5,packed] % I tried to define the third level with "cnum", but it is not working. Some official documents has their own numbering system. In that case, it is very convenient to define new itemgroup following its rule and forget defining the symbol for each level every time. There is no problem to use predefined symbols but I couldn't succeed to insert my defined symbol for some level. Is there a way to do that? Thank you again. Best regards, Dalyoung

Turn Off Header and Footer
by Bene dikt 17 Jul '11

17 Jul '11

Hi, I'm writing a report about my internship at the moment with ConTeXt. There's one problem: I would like to turn off the header and footer on the page with the table of contents. I've found the command "\page[header,footer]" but it has no effect. :( Command reference for "\page" command: http://wiki.contextgarden.net/Reference/en/page Here you can see my present code: http://pastebin.com/JNtXji1i I placed the "\page" command before "\completecontent" to turn off header and footer, however they are typeset. Maybe somebody has a tip how to solve this problem. Thank you. Benedikt

about suppressing prefix in section number
by Jeong Dalyoung 16 Jul '11

16 Jul '11

Hi, Here are a few questions. 1. The output of \section{one} \section{two} is 1.1 one 1.2 two But is it possible to suppress the prefix chapter number like 1 one 2 two ? 2. When defining custom itemgroup, we can set each level using the predefined item headers, like n, r, 1, 2, ...., and it works fine. I am trying to use newly defined conversion, but I couldn't succeed. Is it possible to set an itemgroup using predefined item and custom made item head like \def\circlednum#1{\uchar{36}{95+#1}} \defineconversion[cnum][\circlednum] ? Thank you and Have a nice weekend. Best regards, Dalyoung

\environment before vs. after \startproduct

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
