Passing variables into context
by Matthijs Kooijman 30 Sep '09

30 Sep '09

Hi all, I've been trying to make a metapost graphic, based on the \textwidth. However, it seems I can't just pass in \textwidth as an option. For example, the following breaks: \startuniqueMPgraphic{HLine} draw origin -- (\MPvar{width}, 0mm); \stopuniqueMPgraphic \starttext \setupMPvariables[HLine][width=\textwidth] \uniqueMPgraphic{HLine} \stoptext with the following error: mplib | mp terminal: >> textwidth ! Undefined x coordinate has been replaced by 0. <to be read again> ; <*> ...d:=3441; draw origin -- (\textwidth , 0mm); It seems that the \textwidth option is not expanded before being passed to MP. Is there any way to force this expansion? I've tried \expandafter (without really understanding what that does), but that didn't help. I've tried putting this graphic as an overlay under an \framed, which allows me to use the \overlaywidth macro in metapost (which I assume is expanded specially by context?). This worked, but is not very elegant. Is there something more straightforward possible? Gr. Matthijs

References like wikipedia
by Xan 29 Sep '09

29 Sep '09

Hi, I just want to define a reference like like wikipedia reference entries. Something like Text\wikiref[\from[this] it's best like that] text \listofwikiref and show wikirefs like "^[number]". I'm sure it's possible ;-) but how to define it?. Any helps? Xan.

What does hangsidefloat do?
by Matthijs Kooijman 29 Sep '09

29 Sep '09

Hi all, I've been fiddling around with floats a bit, and seeing a lot of references to "hangsidefloat". It seems to be the solution to all sorts of floating problems, but I can't really see what it _does_. Looking around the source doesn't really tell me either, so anyone care to tell me what it does and what its numeric argument means? Gr. Matthijs

bibtex referencelist doesn't show up with mkiv

continued itemize
by Jerónimo Alaminos Prats 28 Sep '09

28 Sep '09

Dear all, it seems that \sub don't get along very well with the option "continue". At least, the behavior is different in mkii and mkiv. Check the following example. \starttext \startitemize[n] \dorecurse{3}{\item prueba} \sub prueba \dorecurse{3}{\item prueba} \stopitemize \input tufte \startitemize[continue,n] \dorecurse{3}{\item prueba} \stopitemize \stoptext Jerónimo.

end footnotes before new chapter starts?
by Steffen Wolfrum 28 Sep '09

28 Sep '09

Hi, is there a way to end ("flush") footnotes of a chapter before the next chapters starts? Please have a look at this double-page spread below, please: http://werksatz.com/attachments/spread.pdf Footnote no. 37 should be the first footnote that is printed under the footnote line of the first page of the new chapter (right). This is even more important/annoying when footnote numbering starts at "1" with a new chapter!! Steffen (at MkII)

\pagereference changes spacing in displayed formula
by Sanjoy Mahajan 26 Sep '09

26 Sep '09

Using a \pagereference in a displayed formula slightly changes the horizontal spacing. The shift is small, roughly the thickness of an integral sign. I don't know whether that's considered a bug. Here is the test file. The control test file is the same but without the \pagereference line. \starttext \startformula \pagereference[one]% \int \stopformula \stoptext I noticed the problem on my laptop (Debian, TeXLive 2007, ConTeXt 2008.10.31 13:58) and on the live ConTeXt just now. I found the deviation using the pdf-compare.sh script included below. Run it as follows: pdf-compare.sh file1.pdf file2.pdf It displays an image with light gray where the pages are pixel identical, and red where they differ. (It requires the ImageMagick tools and ghostscript.) #! /bin/bash # Usage: $0 file1.pdf file2.pdf # compares file1.pdf and file2.pdf by converting each page to bitmaps using # ghostscript and then using the 'compare' ImageMagick utility # # Copyright 2007 Sanjoy Mahajan.

Metafun problem

All, I've got the context minimals installed and I'm compiling the following (from the new Metafun manual) using MKIV: \startuniqueMPgraphic{name} path p; p:=unitsquare xscaled OverlayWidth yscaled OverlayHeight; fill p withcolor .625yellow; draw p withcolor .625red; \stopuniqueMPgraphic \starttext Hello, World! \defineoverlay[my graphic][\uniqueMPgraphic{name}] \button[background=my graphic,frame=off]{Go Home}[firstpage] \stoptext No button shows up. Am I missing something? David
