xpdf segmentation fault
by Peter Münster 08 Feb '10

08 Feb '10

Hello, I don't know, if this is a ConTeXt problem (wrong PDF) or an xpdf problem. Here the test-file, whose pdf-result xpdf cannot read: \setupinteraction[state=start] \placebookmarks[chapter] \starttext \chapter{bla} \stoptext Should I report this to the xpdf-authors?

colors without \definecolor
by Philipp Gesang 08 Feb '10

08 Feb '10

Hi all, I understand that in order to use a color with \color[somecolor]{colored text} I first have to \definecolor[somecolor][r=.4,g=0,b=1]. Currently I'm trying to do automated colorizing with the help of some lua code and I'd like to make up rgb vectors on the spot without having to \definecolor them first, e.g. something like \color[r=.4,g=0,b=1] {colored text}. Is there a way to achieve this in mkiv? (Right now I'm assigning new rgb values to the same color "name" whenever the function is called that concatenates the next \color[]{} statement. This seems a bit verbose and hacky to me.) Thanks in advance, Philipp -- () ascii ribbon campaign - against html e-mail /\ www.asciiribbon.org - against proprietary attachments

blanks with glue in mkiv

Hi, Blanks with glue do not work with MkIV. For example, \defineblank[test][3pt plus 1pt minus 1pt] \starttext some text \blank[test] some text \stoptext gives ! Missing number, treated as zero. <to be read again> p <argument> p lus \addaskedblankskip ...nce \blankskip #1\dimexpr #2 \relax l.11 } \dovspacingyes ...ument #1\else \s!default \fi ")} \fi l.5 \blank[test] Aditya

DIY toc (or similar list)
by Thomas A. Schmitz 08 Feb '10

08 Feb '10

Hi experts, I'm thinking about a new presentation style and need some general advice from the TeXperts. I would like to have a list of topics on some area of the slide (similar to s-pre-19.tex). However, if at all possible, I would like it to be a bit fancier. Let's say I want the list of topics typeset in gray frames in a black font, but the current topic in a blue frame with a white font. Would this be possible with something like \definelist? Is there any notion of "currentlistitem" or "currentmarking" in such lists? Or, even better: would it be possible to have access to the single members of a list and maybe compare them to a current value and then typeset them accordingly? Something like this pseudocode: for member in topiclist do if member == currentvalue <some fancy framing and metapost stuff with member> else <less fancy but still nice-looking metapost stuff> end end Or am I trying to reinvent the wheel here? I would be happy to hear any ideas on that. All best Thomas

simple usage of \hpos
by Peter Münster 07 Feb '10

07 Feb '10

Hello, How can I place an element as background at a previously defined position? Here a test-file to show what I'm looking for: \definelayer[graphics][position=yes] \setupbackgrounds[page][background=graphics] \starttext Here is some text. I would like to appear a graphics exactly behind \hpos{XXX}{HERE}. How can I do this, without measuring by hand the x- and y-offsets, and perhaps also without using metapost? Such a command would be fine: \type{\placeatpos[XXX]{my background figure}}, or \type{\setlayer[graphics][location=XXX]{...}}. \setlayer[graphics][dx=128mm, dy=-27mm]{\externalfigure[hacker.jpg][width=1cm]} \stoptext TIA for any help!

Changing Index Format
by Tom 07 Feb '10

07 Feb '10

Could someone point me to documentation that describes how to change the format of the index created by \placeindex and \completeindex? In particular, I want to get rid of the entries created for the letters of the alphabet because I find them an unnecessary use of space.

texshow-web (was: colors without \definecolor)
by Mikael Persson 06 Feb '10

06 Feb '10

Dear list and Patrick, from texshow-web page ( http://texshow.contextgarden.net/ ) I read "texshow-web is a web application for all user-commands that can be used in ConTeXt." However, I see that \colored is not inthere. This is also true for some other commands appearing at this list occasionally (usually dug from source by Wolfgang). Is this because 1) the texshow is not updated? 2) these commands are "not meant" for users? 3) any other reason? I think the texshow-web is a very useful source of information. An updated version would be really wonderful! /Mikael ---------- Forwarded message ---------- From: Wolfgang Schuster <schuster.wolfgang(a)googlemail.com> Date: Fri, Feb 5, 2010 at 8:31 AM Subject: Re: [NTG-context] colors without \definecolor To: mailing list for ConTeXt users <ntg-context(a)ntg.nl> Am 04.02.10 21:41, schrieb Philipp Gesang: > > Hi all, > > > I understand that in order to use a color with \color[somecolor]{colored > text} I first have to \definecolor[somecolor][r=.4,g=0,b=1].

context minimals
by Martin 'golodhrim' Scholz 06 Feb '10

06 Feb '10

Hi Hans, hi list, some questions for the minimals, used the texlive version up to now and then found out that the 2k9 version of texlive has problems using context mkii and mkiv. so now I will start to use context from the minimals. so would be nice to have some infos before starting. Is the howto in the contextgarden-wiki still up to date or something needed to be changed in there? Is the repository for the minimals only available via rsync or as git too? And if there is no git version available is it planed to get a git repo, or can one simply add one, as I would write an ebuild for funtoo afterwards it would be easier for me to sync it that way, because it is faster and only updates changes, compared to rsync. If wished I could first make my github-account available for a git repo. Greetings Martin 'golodhrim' Scholz
