Ugly bug with TikZ in recent ConTeXt MKIV
by Mojca Miklavec 18 Nov '10

18 Nov '10

Dear Hans, The following example worked perfectly fine with the version of ConTeXt MKIV I was using one hour ago (no idea which version, but something less than two weeks old). It still works OK with MKII and it works much worse in the real document that I'm using. In my document both images are completely screwed up. Here it's only the second one and if I comment out the first one, the second figure comes out fine, so I'm a bit clueless about what magic is going on inbetween. Nothing in TikZ has changed (I'm still using the "frozen" version from November 2009 from minimals), so it must have something to do with ConTeXt MKIV. It just messes up with some boxes on the page in some unpredictable way. \usemodule[tikz] \starttext \placefigure[force][BCl3 sigma]{x}{ \hbox to .9\textwidth{\hss\starttikzpicture \node[circle,inner sep=0pt] (B) at (0,0) {B}; \node[circle,inner sep=0pt] (a1) at ( 90:0.9cm) {Cl}; \node[circle,inner sep=0pt] (a2) at (210:0.9cm) {Cl}; \node[circle,inner sep=0pt] (a3) at (330:0.9cm) {Cl}; \draw (B)--(a1); \draw (B)--(a2); \draw (B)--(a3); \stoptikzpicture \hbox to 2cm{} \starttikzpicture[>=stealth,very thick] % \node[label=above:$a_1$] (a1) at ( 90:1cm) {$a_1$}; \node[circle,inner sep=0pt] (a1) at ( 90:1.2cm) {$a_1$}; \node[circle,inner sep=0pt] (a2) at (210:1.2cm) {$a_2$}; \node[circle,inner sep=0pt] (a3) at (330:1.2cm) {$a_3$}; % \draw[->] (0,0)--(-30:1cm); % \draw[->] (0,0)--( 90:1cm); % \draw[->] (0,0)--(210:1cm); \draw[->] (0,0)--(a1); \draw[->] (0,0)--(a2); \draw[->] (0,0)--(a3); \stoptikzpicture\hss} } \stoptext Thanks, Mojca

MetaPost version of the Gantt chart module
by Reviczky, Adam 18 Nov '10

18 Nov '10

Hi, I've made a MetaPost version for creating Gantt charts. Florian: The label alignments are fixed in this module. Further, it should be trivial to place the names into the ganttbars, for both versions. For more information see the wiki entry: http://wiki.contextgarden.net/Gantt_charts Adam

Help Winedt 6.0 MikTeX 2.9 ConTeXt
by barney schwartz 18 Nov '10

18 Nov '10

MikTeX 2.9 says ConTeXt is once more available. Winedt 6.0 provides a drop-down menu However, ConTeXt fails to execute. I having been waiting sin MikTeX dropped ConteXt support and was SO happy to see it included once again. Anyone got any ideas how to make ConTeXt functional using MikTeX 2.9 and Winedt 6.0??

Choosing TeX um ... stuff
by Peter Davis 18 Nov '10

18 Nov '10

I've been on the periphery of TeX for years, as a casual user of LaTeX and also as an implementer of publishing software. However, I'm afraid I haven't kept in as close touch as I'd like, and now I find myself trying to absorb a lot in a short time. I'm trying to choose what software to use in building an XML->TeX workflow. I'd appreciate any help with the following questions: 1. True or False: TeX can be categorized along three orthogonal axes: 1. by format (plain TeX, LaTeX, ConTeXt, others?) 2. by implementation (web2c, pdfTeX/pdfLaTeX, LuaTeX, others?) 3. by distribution (MikTeX, TeXLive, MacTeX, others?) 2. True or False: plain TeX and LaTeX(2e) are warhorses ... been around for decades, quirks well known, lots of documentation, etc. 3. True or False: ConTeXt is newer, with a lot of built-in features, but still changing quite a bit from build to build. Other comments welcome vis. picking which software to use. One point is that since the actual TeX input files will be generated programmatically, readability or ease-of-coding is not a factor. I was going to use plain TeX, but it seems a lot of features like placing text boxes and graphics anywhere, using system fonts, etc. are more available for LaTeX and ConTeXt. Thank you for any comments! -pd

ppchtex questions
by Jörg Hagmann 18 Nov '10

18 Nov '10

I just started using (and liking) ppchtex, and I have a few questions: 1. Is there a way to define a frame offset (there is "fit" and there are dimensions, but an offset would be more convenient)? 2. Is it possible to move the "\bottext" further down? It gets too close to the formula, especially with larger fontsize and smaller formula structures, see example)? \starttext \usemodule[chemic] \startchemical[width=fit,scale=small,size=big] \bottext{α-Glycerophosphate} \chemical[ONE,SB1357,Z0357][\TL{α}{C},\SL{OPO\lohi{3}{2-}},H,H] \chemical[MOV1,SB137,Z037][C,\SL{OH},H] \chemical[MOV1,SB137,Z0137][C,H,\SL{OH},H] \stopchemical \stoptext By the way: X_subscript and X^superscript don't work within \SL{...}. 3. How can I get \ss for *all* the atoms in the formulae and in the bottom text (I tried a few things within \setupchemical)? Thanks, Jörg

Horizontal & vertical shift when inserting multipage PDF
by Procházka Lukáš Ing. - Pontex s. r. o. 18 Nov '10

18 Nov '10

Hello, just a brief question. How to avoid the horizontal and vertical shift which appears when inserting another PDF, both PDFs created "with the same options"? You can see page numbers and also the left "edge" shifted. (I'd need this to insert multipage scanned documents into the main PDF.) See the code (and result in the attachments): --- 1.mkiv \starttext \dorecurse{8}{\input tufte\par} \stoptext --- 2.mkiv \starttext AAA\page \copypages[1.pdf]\page BBB \stoptext --- Cheers, Lukas -- Ing.

displaystyle switched off?
by Mojca Miklavec 17 Nov '10

17 Nov '10

Dear Hans, in a recent version of ConTeXt the \displaystyle seems to be "switched off" inside \startformula in MKIV (\sum has no subscript): \starttext \startformula P^{(α)} = \sum_{a\in{\cal G}} χ_a^{(α)}T(G_a), \stopformula \stoptext In current version (tlcontrib's update to TL) and in MKII it works fine.

Stepping mechanism in MkIV
by Aditya Mahajan 17 Nov '10

17 Nov '10

Hi Hans, The current stepping mechanism (s-pre-60) is not too convinient because you have to click the screen to go to next screen. It will be nice if one could go to next screen using page down (and to previous screen using page up). Another annoyance is that it only works with acroread and does not work with evince (I don't know how well it works with preview). Are there any plans to have a mkiv based stepping mechanism? If so, it will be nice to have an option to be able to create multiple pages, one for each step. Thanks, Aditya

Zooming in to a specific part of the page
by Aditya Mahajan 17 Nov '10

17 Nov '10

Hi, Is it possible to zoom into a specific part of the page? I am thinking of the following scenario. Suppose I have the following document \setuppapersize[S6][S6] \starttext \placefigure[right,none]{\externalfigure[dummy][width=0.3\textwidth]} \input knuth \page \input tufte \stoptext I want that when I click on the image, the pdf is zoomed in so that the image occupies the full screen[1], and when I click on the zoomed in image, it zooms out and I get the previous page view. How do I achieve this? I am guessing that some javascript magic might be needed, but I do not understand the interaction code at all. This feature will be pretty handy for presentations. Thanks Aditya [1]: I do not know if the pdf reader knows the screen size. Assuming that the screen aspect ratio is the same as the page aspect ratio might be a good approximation (at least for presentations).
