Possible users meeting?
by Taco Hoekwater 22 May '06

22 May '06

Hi all, On the trip to (and from) Bachotek, Hans and I have discussed a great many topics related to ConTeXt. One of the things we discussed was this: If there is sufficient interest, we could organize a ConTeXt (mini)conference. Tentative programme: friday night : arrivals saturday : talks sunday : talks/tutorials/workshops monday morning : early departures monday : developer meetings & more tutorials We are thinking about spring 2007 (March or April). The meeting place would be the south of the Netherlands, close to Maastricht Aachen Airport. We cannot say how much it would cost without a better idea of number of attendees/programme, but we will try to keep the costs low. Some stuff we really want to know, so we can make a final decision: * are you interested in such a meeting? ("no" is also an interesting answer!) * would you be willing to give a talk or tutorial? (Hans and I cannot talk for three days straight) * are you happy with planning/programme? (any special requests about topics?) NOTE: In the interest of email traffic control we request that if you only reply "yes" or "no", then please reply to me *personally*, and no to the entire list. Thanks in advance. Greetings, Taco (also talking for Hans)

Math encoding in XeTeX
by Ricard Roca 22 May '06

22 May '06

Hi, With ConTeXt and pdfTeX you can use \enableregime[utf] (utf8 encoding) with normal mode and math mode (no need to write \pm, \alpha or \times). But with ConTeXt and XeTeX you don't have to specify utf8 regime, because XeTeX can read utf8 directly. However, math mode in XeTeX is a different story ( 256 character tfm's are needed and so, and the encoding has to be ascii, so you have to write \pm, and ± doesn't work). It would be nice if utf8 regime (using uni-xxx files) could be enabled only for math mode when using XeTeX, and so you would be able to input unicode characters in all modes (normal and math). Thanks in advance, Ricard Roca

slithering captions
by Sanjoy Mahajan 22 May '06

22 May '06

One weekend years ago I studied tex's insertions and learnt enough to write (i.e. hack) macros to produce a layout that I'm trying to reproduce using ConTeXt. I've figured parts of it out, no doubt the easier parts. The layout has a 4in text column and a 2.3in right margin for figures and captions. Experiments with setuplayout got those blocks working. But figures are to be placed according to their width. Three natural widths appear in the layout: 1. margin (2.3in) 2. text (4in) 3. text + margin (+ gutter) = 6.5in You can see the results of the plain-TeX implementation in the book chapters at <http://www.inference.phy.cam.ac.uk/sanjoy/mit/>. A figure is then placed in one of three ways: 1. width <= margin: margin float, with caption below it. One example is p.8 of chapter 1. 2. width <= text: float to top of page, with caption in the right margin. One example is p.7 of chapter 1. 3. width <= text + margin + gutter: float to top of page, bleeding into the margin, with caption below it in the margin. One example is p. 11 of chapter 1. So the first step in doing the placement automatically is to get the width of the figure. Assuming that I've done \useexternalfigure[fig_a][f-1.pdf] is there an easy way to get fig_a's dimensions? After using the figure, e.g. with \placefigure[margin][]{some caption}{\externalfigure[fig_a]} then \wd\floatbox has the dimension I need. Will another macro fill in \floatbox without doing the work of using the figure? I tried \dogetfiguresizetex but probably with wrong arguments. Another option was \newdimen\a \newdimen\b \newdimen\c \newdimen\d \dogetPDFmediabox{f-1.pdf}{\a}{\b}{\c}{\d} and then \c has the width, but without any scaling and only for pdf figures. Once I have the width, I can define \autofig and use it like so: \autofig{L}{caption} and \autofig will look up the width of the figure labeled L and do roughly: \placefigure[margin][]{caption}{\externalfigure[L]} % margin figures OR {\setupcaptions[location=middle] % for text figures \placefigure[top][]{caption}{\externalfigure[L]} } OR {\setupcaptions[width=2.3in,align=right] % for even wider figures \placefigure[top][]{caption}{\externalfigure[L]} } The next problem after finding the figure width is to find the right alternative to location=middle (which puts the caption to the left, whereas I wanted it in the margin and to the right). And, but this is trying to do too much at once, the next problem is that margin caption below the widest figures (case 3 above) shouldn't overlap other floats in the margin and also shouldn't count toward the figure's height in the text block. But maybe that's done automatically -- I'll make some experiments. Any hints greatly appreciated, and, once I get it working, I'll wikify the layout if there's interest. -Sanjoy `A society of sheep must in time beget a government of wolves.' - Bertrand de Jouvenal

Text style in bookmarks
by nico 22 May '06

22 May '06

Hello, Is there a trick so that I can put styles like {\bf ...} or {\tt ...} in the headings without having any weird text in the bookmarks? Adding \bf or \tt as empty macros to the simplifiedcommands doesn't avoid the curly braces to appear (which is normal). Do I need to use something like \def\textbf#1{\def\textbf#1{\bgroup\bf #1\egroup} to have this working? Thanks for any hint. Regards, BG

texmfstart problem
by Richard Gabriel 22 May '06

22 May '06

Hello Hans and others, I've got the following problem... I used to use such a command to compile my documents: texexec --format=cont-cz --mode=print file.tex After upgrade to latest ConTeXt (2006-05-17), I got a warning "Use 'texmfstart texexec' instead!". So I've changed my batch to call: texmfstart texexec --format=cont-cz --mode=print file.tex But it seems the --format switch is not processed correctly because the cont-en format is always used. On the other hand, the mode is passed correctly. Where's the problem? Thanks, Richard

open math
by Hans Hagen 21 May '06

21 May '06

Hi, For those interested in mathml/openmath ... i've added some support for openmath -> mathml conversion to the distribution (there is some stuff in the manual svn repos as well). I dunno how many of you actually have used openmath. Anyhow, it makes a nice demo of applying ctx job description files (used for automatic preprocessing of the xml files to content mathml and such). http://www.pragma-ade.com/general/manuals/mmoexamp.pdf Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

Problems when using columnset and certain fonts
by ME 21 May '06

21 May '06

Hi all, I'm currently playing with context columns / columnsets and several fonts. I've come across a strange problem with columnsets when using certain fonts. I first noticed it when I tried to use one of the Windows TTF fonts, Times New Roman. That's the one I've mainly used in the past with Latex. I've been through all the steps described in the wiki, the practex 2005/2 issue or Bill McClain's context/pdftex beginner's page to embed TTF into context. The problem I encountered was that typesetting with some fonts goes terribly berserk when switching between \tf and \it and back. I thought this was just 'me' because I don't know much about context yet, and integrating ttf is complicated. So I looked at http://www.fiee.net/texnique/?menu=0-1-4 (it was mentioned in January in the 'Problems installing Gentium TTF' thread) which has some font definitions for context. I tested all of them and guess what, one of them shows the same problem. It's the phosphorus font, which I used to cook up a minimal example, just that anybody can test it without my own local font definitions, which may be wrong anyway. So here's my questions regarding this phenomenon. 1) Is it a problem with the font being used? (In this case there's probably no workaround and certain fonts simply can't be used). 2) Is it a problem with the font/typescript definition files? If so, how can it be fixed? (This would be my favourite, it would mean it can be fixed locally, althogh this also means I made a mistake somewhere :-)) 3) Is it a problem within the context columnset? (This I wouldn't like much since I couldn't fix it myself...) It would be nice if one of the wizards could look into this, because it puzzles me no end... I'm using miktex on windows xp sp2. For version information, the log file says: TeXExec 5.4.3 - ConTeXt / PRAGMA ADE 1997-2005 ConTeXt ver: 2006.04.24 23:37 fmt: 2006.5.16 TeXUtil 9.0.1 - ConTeXt / PRAGMA ADE 1992-2006 Find the minimal example below.

This is on Suse 10.1. by default, it ships with a cont-usr.tex in /etc/texmf/tex/context/config/ which takes precedence over everything else.

Margin definition trouble.
by Johannes Graumann 20 May '06

20 May '06

Hello, I define my margins like so: % Papersize is 'letter' \setuppapersize[letter][letter] % CIT thesis regulations: 1 in margins, 1.5 in on the binding side % Johannes: no footer \setuplayout[ margin=1in, backspace=1.5in, footer=0in ] but the margins on top, bottom and right differ significantly from 1 in (ca. 1 in 3/16) and on the left from 1.5 in (ca. 1 in 11/16). This is in the printout. Do I have to go adjusting this arbitrarily, printing it and checking manually? Can anybody tell me what I'm doing wrong? Joh
