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 19 Dec '12

19 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

Transparency without colors.
by Andre Caldas 18 Dec '12

18 Dec '12

Hello! In my "simplesteps" module, I'd like to adjust the transparency of the foreground color. The file tex/context/base/colo-ini.mkiv suggests that there is a way to do that: % Currently in mkiv transparency is implemented independent of color. This costs % a bit more processing time but gives the possibility to apply transparency % independently in the future. Is this useful? If not we may as well combine them % again in the future. By coupling we are downward compatible. When we decouple we [...] How can I define the transparency of some text? André Caldas.
