Page Break Events
by Andreas Schneider 01 Jul '09

01 Jul '09

Hello, since that question has probably gone by unnoticed in my other posting, I'll ask more directly here: How can I react on page breaks (in MkII)? More specifcally: I need to reset a variable whenever a pagebreak occurs (atleast when automatic page breaks occur ... but it would be nice, if it also works for manually broken pages). The only thing that I was able to find was \insertpagebreakhandler ... but it seems as if this can only be triggered manually with \page. Thanks in advance! Andreas.

How to Determine the Current File Name and Line Number in the ConTeXt Source?
by Tad Ashlock 01 Jul '09

01 Jul '09

Is there a convenient way within a Lua block to determine the current file name and line number of the source file being processed by ConTeXt? For example: (test.tex) --------------------------------- \def\ShowLineNumber{% \ctxlua{print('current line number:', tex.current_line_number()) print('current file:', tex.current_file_name())}} \starttext a line \ShowLineNumber another line \ShowLineNumber \stoptext --------------------------------- With the following displayed: --------------------------------- current line number: 6 current file: test.tex current line number: 9 current file: test.tex --------------------------------- I've considered hooking into the open_read_file callback and tracking the file name and line number (via reader) myself. But that seems a bit heavy handed if the file name and line number information are available more directly. And since that information is needed for error reporting, I'm thinking there's a good chance it is accessible. (Just in case you're interested, the purpose of this is to be able to assemble code segments during the ConTeXt processing into external files with #line directives ala the C preprocessor. That way if the subsequent compilation of the external file results in an error, the error message can refer back to the line of code in the ConTeXt source file. This is part of the literate programming module that Kevin Robbins has been describing in another thread.) Thanks, Tad

Turning slides in unattended presentation
by Vyatcheslav Yatskovsky 30 Jun '09

30 Jun '09

Hello, Is it possible to make slides (i.e., PDF pages) to turn automatically, say, every 10 seconds (and start again, in loop)? I suppose that Reader is in full-screen mode (Ctrl+L). I already have nice transitions between slides, making the presentation unattended is the main thing I lank now. Vyatcheslav

Conditional commands
by Andreas Schneider 30 Jun '09

30 Jun '09

Hi, I'm currently trying to make a command that outputs different text depending on the situation it has been called, but I'm absolutely stuck there (I'm not very familiar with TeX, so it's probably obvious to most of you :-/). It currently looks like this: \doassign[mycite][last=] \def\mycite[#1]{% \footnote{% \doifelse{\mycitelast}{#1}{Ebenda}{\cite[alternative=data][#1]}% } \doassign[mycite][last=#1] } The idea is as follow: if I cite the same citation two or more times in a row (e.g. Some text\mycite[chan_genetic_2005] ... more text\mycite[chan_genetic_2005]) it should only output the whole quotation the first time, and "Ebenda" all the other times. But as it seems, the \doifelse always evaluates to false and therefore outputs the whole citation every time. Does someone see what I might be doing wrong? Or is there even a better way to do this? Thanks, Andreas.

Example of passing unexpanded text between \startfoo ... \stopfoo into Lua?
by Kevin D. Robbins 30 Jun '09

30 Jun '09

Hi Hans and others, I've been searching the mailing list and source code for one or more examples of passing unexpanded text appearing between a \startfoo ... \stopfoo block into Lua, but without luck. Is there such an example you could point me to? A colleague and I are experimenting with strategies to implement a literate programming module for ConTeXt, and we'd like to have something like \startcodeblock[language=c,file=foo.c, etc.][blockname] // This is the main routine... int main() { return 0; } \stopcodeblock We would appreciate any thoughts you have about how to implement such a module. Thanks, Kevin

Re: [NTG-context] figure captions in the margin
by Richard Weickelt 30 Jun '09

30 Jun '09

Hello, I want to have captions for figures, listings and other stuff inside the document margin. I saw that somone asked a very similar question 3 years ago: http://archive.contextgarden.net/message/20061025.211202.c2e04f8c.en.html > > Does somebody know whether it is possible and how it is possible to > > place the caption of a figure in the margin? > > > yes, actually i implemented this last week but i need to update the details manual; captions can go in margins, hang in centered figures, there is support for all kind of inner/outer alignments etc Hans said, that he had already implemented that feature, but in fact it still doesn't work. So the code \setupcaptions[location=outermargin] \starttext \placefigure{Caption}{\framed{Figuur}} \stoptext still prints no caption at all. Am I missing something? Thank You. Best regards Richard

Can't change typeface without type size
by Maurício 29 Jun '09

29 Jun '09

This seems to be a small bug. This works well: %%%% \usetypescript[pagella] \usetypescript[chorus] \setupbodyfont[pagella,22pt] \starttext Text on body font. { \switchtobodyfont[chorus,21pt] Text on special typeface. } \stoptext %%%% However, if I either remove '21pt' from \switchtobodyfont or just change it to '22pt' (i.e., no change from body font size) I don't get text for the other font. (This is not specific to pagella and chorus, I've checked this same problem with all other combinations I tried. I'm using latest version in minimals, i.e., did 'sh first-setup.hs' just half an hour ago.) Best, Maurício

spanish tilde-n lost
by Ciro Soto 29 Jun '09

29 Jun '09

Hi all, I finally got around the intallation of context minimals. Thank you for those who helped. I ran my old tex files (in spanish) and found that \~n is not working now. It should create an n with a tilde on top, but what happens is that there is no letter printed at all. What is the fix for this? Any switch? (I know I could use \char but I am looking for a more elegant solution) thank you Ciro

Footnotes in multiple columns broken
by Khaled Hosny 28 Jun '09

28 Jun '09

The 'n=' option to \setupnote doesn't have any effect, more ever 'n=0' will give an "Arithmetic overflow" error. Minimal example: \setupnote[footnote][n=0] \starttext This\footnote{one} and this\footnote{two} and this\footnote{three}. \stoptext Regards, Khaled -- Khaled Hosny Arabic localiser and member of Arabeyes.org team Free font developer
