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].

But the second between #1 and #2 is NEEDED. A last blank after #2 is not needed and not eaten. Wolfgang

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

context mkiv metafun
by Martin 'golodhrim' Scholz 06 Feb '10

06 Feb '10

Hi list, another problem I encountered while installing and testing context- minimals is that the context command is not willing in my case to autobuild the metafun graphics I included in the document. Would be nice if someone has an advice to me on to fix that, got it working under texexec by creating a cont-sys.tex and linking it to the directory where cont-sys.ori is located. Greetings Martin 'golodhrim' Scholz

overlay at given position: help needed
by Peter Münster 05 Feb '10

05 Feb '10

Hello, Below is a test file, to show a bit what I'm looking for: a background-image behind a text-area at a given position relative to the center of this area. I'm not yet satisfied with the result. Here my questions: 1.) Is \startframedtext a good choice for placing the background, or is there something better? 2.) Is \framed[loffset=..., toffset=...]{} a good choice for specifying the position, or is there something better? 3.) When "left=1", why is the image completely outside the frame and not only 50%? 4.) How do I make a step between text and background according to http://wiki.contextgarden.net/Presentation_effects ? I would like to show first the text, and after a mouse-click the background image. Thanks in advance for any help! Cheers, Peter The test-file: % Begins a text-area with a background-image: \def\startBGimg[#1]{% \getparameters[BGimg][top=0, left=0, width=2cm, #1]% \start \newdimen\TopOffset \newdimen\LeftOffset \setupframedtexts[before=, after=] \defineoverlay[myBG][{% \TopOffset=\overlayheight \LeftOffset=\overlaywidth \TopOffset=\BGimgtop\TopOffset \LeftOffset=\BGimgleft\LeftOffset \framed[frame=on, width=\overlaywidth, height=\overlayheight, offset=overlay, toffset=\TopOffset, loffset=\LeftOffset]{% \externalfigure[\BGimgimg][width=\BGimgwidth]}}] \startframedtext[background=myBG, frame=off, offset=overlay, width=\textwidth]} % Stops the text-area with a background-image: \def\stopBGimg{\stopframedtext\stop} \starttext \startBGimg[img=hacker.jpg, top=-1, left=-1] \input tufte \stopBGimg \startBGimg[img=hacker.jpg, top=-1, left=1] \input tufte \stopBGimg \startBGimg[img=hacker.jpg, top=1, left=-1] \input tufte \stopBGimg \startBGimg[img=hacker.jpg, top=1, left=1] \input tufte \stopBGimg \stoptext -- Contact information: http://pmrb.free.fr/contact/

Any syntax highlighter for C++ MKIV?
by seasoul 05 Feb '10

05 Feb '10

The verbatim function in MKIV is really powerful, and pretty printing of progamming language is easy. But unfortuantely, I do not know how to modify the php, or lua pretty printing formatter to what I want --- C++ formatter. After laboriously searching, I failed to find any working formatter. Is this really really easy, nobody wants to post it? Or there is no person in need of such a formatter, but only me? I tried vim highlighting module in the wiki, but it always complains cannot find "xxx-vimsyntax.tmp" and something, in both windows and unbuntu. I know it is something about mtxrun curruent version. But I still cannot fix it after I did following the posts in this mailing list.
