Hello! How can I have a "framed text" that can cross page boundaries? Cheers, André Caldas.

Odd /externalfigure behavior
by Guy Stalnaker 21 Dec '12

21 Dec '12

All, I've been working on a document for weeks and it's been compiling fine. I have a pdf copy from yesterday afternoon at 4p local time, the last time it compiled successfully. I was doing a search/replace on some /crlf to add space between text and an image. The search/replace with Gnome's gedit included \n in both search and replace string. Suddenly context will no longer successfully compile the document! What's very, very odd, is that the context document is an output file from pandoc of a markdown document that has had no issues until now. If I go back now to the original markdown doc and regenerate the context document the issue persists with or without subsequent edit!! Damned peculiar. Here's the workflow: pandoc -s -f markdown -t context <file.md> -o <file.context.tex> gedit <file.context.tex> to add: \defineexternalfigure[screenshot][frame=on] and then add [screenshot] to all of the \externalfigure directives. Then find the /crlf that appear immediate before *all* of the \externalfigure directives and double them (unless someone who reads this can tell me how to easily modify the padding of an image when it's placed to increase the spacing between the image and the text above it). I've been doing this for many days. Until late yesterday afternoon. Now context spits out this: <quote> structure > sectioning > subsubsubsection @ level 6 : 0.0.0.1.3.1 -> One URL for All Projects !

I can successfully use display from the commandline in the same dir as the context file on that path shown in the quoted output and it opens the image.

problems with units
by Andreas Mang 21 Dec '12

21 Dec '12

Hi there, I encountered some problems with the built in units command in MKIV. I provide a minimal example which should demonstrate my problems. Maybe I am doing something wrong... Cheers, Andreas %%%%%MINIMAL EXAMPLE%%%%% \setupbodyfont[pagella] \starttext % this is just my default setting - if I comment the next line I get the same behaviour \setupunits[method=3,order=reverse,separator=small] \unit{11,1e-1 micro mol per second} \par %no effect if I change the separator (holds also for cdot) $\unit{11,1e-1 micro mol per second}$ \par %wrong spacing \unit{11,1e-1 per second} \par % one over is not working (no unit displayed) \unit{11,1e-1 / second} \par % one over not working (no unit displayed) \stoptext %%%%%MINIMAL EXAMPLE%%%%%

Balanced parenthesis.
by Andre Caldas 20 Dec '12

20 Dec '12

Instead of writing $\left( x+y \right)$, I'd like to simply write $(x + y)$. For unmatched parenthesis, I would like to write $:-\unmatched)$. How can I accomplish that in context? Cheeers, André Caldas.

Broken footnote-numbering in the latest beta
by Jannik Voges 19 Dec '12

19 Dec '12

Hello, When I use \setupnotation[footnote][way=bypage] in the latest beta to reset the footnote counter on each page, that doesn't work anymore. Minimal example: \setupnotation[foonote][way=bypage] \starttext Text\footnote{a footnote}, Text\footnote{another footnote} \page Text\footnote{a footnote with wrong number}, Text\footnote{another footnote with wrong number} \stoptext Jannik

Is there a way to for ConTeXt to do basic arithmetic operations? For example, \calc{1+2} and have it return 3 or \calc{1/3.8} and have it return 0.263157894736842 (or rounded) Troy

Wrong float numbering with default=top
by Marco Patzer 19 Dec '12

19 Dec '12

Hi, The setting \setupfloat [figure] [default=top] not only places the figures at the top of the page, but also messes up the float numbering (the float placement is fine). In the following example “Figure 2” comes after “Figure 3”. How to fix that? \useMPlibrary [dum] \setupfloat [figure] [default=top] \starttext \input knuth \startplacefigure \externalfigure [dummy] \stopplacefigure \startplacefigure \externalfigure [dummy] [width=10cm, height=16cm] \stopplacefigure \startplacefigure \externalfigure [dummy] \stopplacefigure \stoptext Marco

Hi Philipp, thanks alot! It works, one question left: What is the --silent flag, what is its effect, I tried it but could not see the difference. Thanks alot again, very kindly :) Best Regards Huseyin

one small remark and one broad question
by Thomas A. Schmitz 19 Dec '12

19 Dec '12

Hi all, small remark first: archive.contextgarden.net has been down for a few days now; I suppose because of the new server? And now for the overly broad question: I'm embarking on what could become a long project. One part of it is typesetting a book (with many graphics). On the one hand, it would be wonderful to use the project structure and break it down into several components to make things manageable. On the other hand, it would be great to code in xml (because I might want to publish this as a website too). can these things be combined? Does the xml engine handle xinclude (or could this be added to it)? Or would another approach be better? Thanks for your insights! All best Thomas
