Thanks Wolfgang, these are very valuable tips for me for the future. I put them to special document for later use. Thanks again for the valuable advice.

Hello Wolfgang, I like your solution and will take it.

OT: Problem with writing macros into variables in LuaTeX
by Jaroslav Hajtmar 18 Mar '12

18 Mar '12

Hello Gurus. Sorry for OT, but I solve one problem in parallel in ConTeXt and pure LuaTeX too and I got into trouble. I have a problem in LuaTEX with putting macro name into global variables and their re-listing. In ConTeXt, the problem is not with it. Here is my minimal LuaTeX example: \directlua{function put2globvar(parameter) globvar=parameter end} \directlua{function getglobvar() tex.print(globvar) end} \def\puttoglobvar#1{\directlua{put2globvar('#1')}} \def\globvar{\directlua{getglobvar()}} % OK Text -- \puttoglobvar{Text} \globvar % OK $\alpha$ -- \puttoglobvar{$alpha$} \globvar % not working $\alpha$ -- \puttoglobvar{$\alpha$} \globvar % Error ... %\puttoglobvar{$\\alpha$} %\globvar \bye Can you please advise? Thanx Jaroslav Hajtmar

Good morning :-) I am still not able to rotate the buttons without loosing the hyperlinks; see code at the bottom. And I have an extra question: How can I make a linebreak after each button.

Re: [NTG-context] Color Lost when Using 'texexec' vs 'context'
by Malte Stien 18 Mar '12

18 Mar '12

Mojca, Wolfgang, Thank you for explaining that. I had read about the two different versions MkII and MkIV, but did not realise that 'texexec' is the former while 'context' is the latter. > How old was the manual that you were reading? I got that from the "Context Manual" ("Context Manual (cont-eni).pdf"), Section 1.4, which I downloaded quite recently from the website (I have been using Context for less than 2 months). It is dated November 2001, so quite old, you're right. What should I be reading instead? Is there something newer? The reason I switched to "texexec" was this (from the "Context Manual": "During the processing of itemizations the number of items is counted. This is the case with all versions. The next pass this information is used to determine the optimal location to start a new page. So do not despair when at the first parse your itemizations do not look the way you expected. When using TEXexec this is all taken care of." Is this still a problem with "context" or is this problem somehow solved with MkIV anyway? Thank you for all your help; this mailing-list proves very helpful to a novice like me. Regards, Malte.

Hi Wolfgang, > Use also the "broad" keyword for align which makes ConTeXt more tolerant to break the line with ragged text. That did the trick. Thank you so much. Regards, Malte.

setupinterlinespace (exact setting, smaller than 1.0)
by Honza Hejzl 17 Mar '12

17 Mar '12

Hello, I am struggling with this for a very long time. I wish to know if there is any sure way how to work with setupinterlinespace when I am setting ON GRID. When bodyfont is, for my example, 9pt and I set up the interlinespace to 10.8 (i.e. 1.0 – small), there are strange line breaks in pages everywhere (as soon as the command \setupinterlinespace is used, doesn't matter how big the number of line is, the text is broken in that way (expecially when I am trying to use smaller distances). I need working on grid with the possibility to reach exact interlinespace (typically to be able to make linespacing tighter) – my editor has often very strict demands for the page range. The once result is the grid is tighter but the lines are not. According to my tests I think there is no possibility to set smaller interlinespace than 1.0, is it? Any ideas, please? Here is the result: http://dl.dropbox.com/u/4393365/interlinespace.png bodyfont 9pt interlinespace 10.8 (for test) Thanks, Honza

mathml question
by Meer, H. van der 17 Mar '12

17 Mar '12

There is something in the processing of mathml I do not understand. I keep the xml-node in a \startxmlsetups my:setup \def\mynode{#1} \stopxmlsetups Doing \xmlflush{\mynode} does typeset the contents of mynode, but not when mynode contains a mathml tree! Then the error is: Undefined control sequence ... \MMLhack ->\let \MMLpar \par \let \par \relax \everyvbox {\let \par \MMLpar } \12>:mml:math ...}} {\automathematics }}{\MMLhack \xmlflush {#1}}\endgroup Tested it with a simple: <math xmlns='http://www.w3c.org/mathml' version='2.0'> <apply><root/> <ci> x </ci> </apply> </math> The strange thing is, when putting the mathlml tree insize <text> mathml-content </text> where: \startxmlsetups xam:text \xmltrim{#1}\par \stopxmlsetups then typesetting goes without an error! Can someone explain this behaviour? Hans van der Meer
