Conflict with chapter definition and header
by Confused Scientist 04 Aug '06

04 Aug '06

Hello, I'm trying to put together a couple of examples I found in the ConTeXt manual, the wiki and the maling list archive. Unfortunately, I've broken my headers/footers in the process. What I am trying to do is have a double-sided layout where (at the beginning of each chapter) a famous quote is given on the left page and the chapter begins on the right. I do not want any header/footer on the left, but I would like the footer (page number) on the right. My problem is that I cannot seem to control the page headers and footers for the left/right chapter page. Also, I cannot seem to get the section name to reliably appear after using setupheadertexts? I am using: TeXExec 5.4.3 - ConTeXt / PRAGMA ADE 1997-2005 texexec : TeXExec 5.4.3 - ConTeXt / PRAGMA ADE 1997-2005 texutil : TeXUtil 9.0.0 - ConTeXt / PRAGMA ADE 1992-2004 tex : pdfeTeX, 3.141592-1.30.4-2.2 (Web2C 7.5.5) context : ver: 2006.02.03 21:03 cont-en : ver: 2006.02.03 21:03 fmt: 2006.2.10 mes: english cont-nl : ver: 2006.02.03 21:03 fmt: 2006.2.10 mes: dutch total run time : 9 seconds and below is an example of what I have.

A bug in character alignment?
by Nicolas Grilly 03 Aug '06

03 Aug '06

Hello, I use ConTeXt natural tables to produce reports, and I use character alignment to align numbers in these tables. For example: \setupTABLE[column][each][align={middle,lohi}, aligncharacter=yes, alignmentcharacter={.}] But I have a little issue with character alignment. I have several tables following each other. First and second tables are well aligned. But following tables have some columns mis-aligned. You can see the result in the attached file report_with_bug.pdf (look at column 4 of tables 3, 4, 5 and 6). If I comment table 2, then the problem disappears. You can see the result in the attached file report_without_bug.pdf. If I uncomment table 2, but move it to end of file, then the problem disappears too. It seems there is some side effect in code managing character alignment: perhaps a global variable is not reset each time a new table starts? The attached file character_alignment_bug.tex contains the code producing the first example, where the bug is visible. I looked through core-ntb.tex and supp-ali.tex but was unable to understand where is the problem. We have lot of tables like this in our production, and some are horribles because of this character alignment issue... Thanks for your help! Nicolas Grilly

Indentation bug ?
by Renaud AUBIN 02 Aug '06

Hi all, Considering the following example: %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \setupindenting[medium,yes] \setupformulas[indentnext=yes] \setupheads[indentnext=yes] \setupfloats[indentnext=yes] \starttext \startuseMPgraphic{mympgraph} numeric u; u:=2cm; draw (-u,-u)--(u,u); draw ((-u,-u)--(u,u)) rotated 90; \stopuseMPgraphic \section{A section} La liaison inter-modulaire conçue par TDA pour le prototype est une liaison pivot d'axe vertical. En effet, même si elle dispose de possibilités de débattements angulaires, ces débattements admissibles sont relativement faibles. De plus, seul la rotation suivant l'axe de la liaison pivot peut être actionné et, en l'état, les débattements ne peuvent en aucun cas être pilotés. Néanmoins, le problème posé par cette articulation ne se pose pas si l'on se restreint à des déplacements sur des surfaces planes ou régulières relativement aux grandeurs du robot. Nous ne présenterons pas ici la conception mécanique de cette liaison. \placefigure[bottom]{none}{\useMPgraphic{mymmpgraph}} La liaison inter-modulaire conçue par TDA pour le prototype est une liaison pivot d'axe vertical.

updating context on Ubuntu 6.06
by Sanjoy Mahajan 01 Aug '06

01 Aug '06

Here's what I had to do to update to the latest Context (2006.07.14) on Ubuntu 6.06 (i.e. 2006.06) distribution of Linux. It comes with tetex 3.0. The commands below assume a working Context already installed in your ~/texmf, and the commands use bash syntax, which is almost like 'sh' but has the ~ idiom for $HOME. Beforehand I had been using the 2006.04.17 beta and had put off upgrading because I was scared of the change from perl texexec to ruby texexec. 1. (optional cleanup) Delete the old Context-installed files in ~/texmf/. This step is optional, but I do it so that I can track the versions using an SCM. I use mercurial (hg is the program name), but it could have been svn, cvs, etc. The command (done in ~/texmf): hg locate -0 | xargs rm -0 2. (download, unpack) Download cont-tmf.zip, cont-fnt.zip, and cont-img.zip. Probably you need only the first zip file, but I'm reporting exactly what I did just in case any substep is the crucial one. The command: cd /tmp/ # no need to save them long-term wget http://www.pragma-ade.nl/context/current/cont-{tmf,fnt,img}.zip Unzip the zip archives into ~/texmf, appending the giant list of files to /tmp/a.log: cd ~/texmf for f in /tmp/cont-{tmf,fnt,img}.zip ; do unzip $f >> /tmp/a.log ;done 3. (stubs, part 1) Create ~/bin/texmfstart containing two lines: #!/bin/bash ~/texmf/scripts/context/ruby/texmfstart.rb "$@" Then make it executable with chmod +x ~/bin/texmfstart From what I can tell from reading the ruby code, using the full path to texmfstart.rb helps texmfstart.rb find the other .rb programs, like texexec.rb. (texmfstart.rb uses the path it was called with and looks in that directory, but Hans can correct me if I'm wrong here.) 4. (stubs, part 2) texmfstart will run texexec, so create texexec as a symlink to ~/texmf/scripts/context/stubs/unix/texexec: cd ~/bin ln -s ~/texmf/scripts/context/stubs/unix/texexec chmod +x texexec Hans: Could texexec be made executable in the distribution's zip file, to avoid the chmod? 5. (test 1) A first check is that texexec works. So change to a random directory, e.g. where you keep some Context files: cd ~/tmp/xy ; texexec --version That produces: TeXExec | version 6.2.0 - 1997-2006 - PRAGMA ADE/POD which looks good 6. (formats) Remake the formats with texexec --make --all 7. (test 2) Try a simple file. I use ~/tmp/xy/t.tex containing one line, "\starttext abc \stoptext". Here goes: texexec t fails with ! Font \*12ptrmtf*=ec-lmr12 not loadable: Metric (TFM) file not found. 8. (dreaded lmodern) Ack, it's the dreaded lmodern problem. I thought I had avoided this issue on my previous laptop, which ran Debian testing/unstable and got reincarnated as an Ubuntu laptop. And I had fixed it, by installing the 'lmodern' package. But Ubuntu lmodern is v0.92, at least as of Ubuntu 6.06, and Debian unstable uses v1.00, which includes the necessary .tfm files for ec-lmr*. The beta Ubuntu ('edgy eft') uses the new version, so I downloaded its .deb via http://packages.ubuntu.com, which eventually pointed me to a monster url and I did: cd /tmp wget http://ubuntu.mirrors.tds.net/ubuntu/pool/universe/l/lmodern/lmodern_1.00-2… Note that the package version may change, so the easiest way is to download the latest .deb from http://ubuntu.mirrors.tds.net/ubuntu/pool/universe/l/lmodern/ Installing it is a bit painful. The first try (done as root) of dpkg -i /tmp/lmodern_1.00-2_all.deb complains with Usage error: unrecognized option Usage: update-fonts-dir DIRECTORY ... 'update-fonts-dir' is some X program that updates X's ideas of where its fonts are, and the package isn't calling it correctly. But I don't care whether X knows about the lmodern fonts, since I'm using them for documents viewed with gv or xpdf, not directly as an X font. So I shut up update-fonts-dir for the moment, installed, and undid the shutting up (all as root): chmod -x /usr/bin/update-fonts-dir dpkg -i /tmp/lmodern_1.00-2_all.deb chmod +x /usr/bin/update-fonts-dir 9. (test 2 again, not as root) Now 'texexec t' works fine, as does 'texexec --check' So I think all is well, and I didn't need to set RUBYLIB. Let me know of any corrections or improvements; if there's interest I'll wikifi. >From now on, I hope I can update using texmfstart ctxtools --updatecontext -Sanjoy `A society of sheep must in time beget a government of wolves.' - Bertrand de Jouvenal

colums
by Hans van der Meer 01 Aug '06

01 Aug '06

When I do: \setupcolumns[n=2,balance=no,tolerance=verytolerant,rule=on] % and variations \startext \startcolumns abc \column def \stopcolumns \stoptext This produces two columns when typeset on the upper half of the page. Suddenly about halfway the page the columns are not put side by side but below each other! Is this something known are am I becoming mad? Hans van der Meer

grid and \textrule
by wwl＠musensturm.de 01 Aug '06

01 Aug '06

Hallo! I use \setuplayout[grid=yes] and a chapterdefinition which looks like: Author ------------------------------------------------- Title Text text text ... The hor. Line above is a \textrule and the vert. spacing between author and line and line and Title resp. should not depent on the grid. So I can not use \placeongrid{textrule} in my chapterdefinition. I have to do this afterwards. \blank[force,3.9pt] In short: \setuplayout[grid=yes] \def\Sync{...} \showgrid \starttext Bla Blub \textrule \Sync Bla Blub \stoptext How should \Sync be defined to snap on the next gridline? My solution is \def\Sync{\blank[force,7.4pt]}% try and error isn't there a better solution? Wolfgang

Rule under length of last line
by Duncan Hothersall 01 Aug '06

01 Aug '06

I've had a last-minute impossible request for a typesetting style, and having already told the person it can't be done in the time available, wondered whether it can actually be done at all. The request is for a subsection heading to have a continuous horizontal rule under both its number and title, at a distance of about 6pt from the baseline (i.e. not underlining), extending just the length of the heading. I can do that by setting both number and title in a TABLE, setting the offsets and specifying the bottom frame to be on - no problem. However, the tricky part is that where a longer title runs beyond one line, the line should only appear under the last line, and only to the length of the last line of text. In other words, for viewers with fixed width fonts: 1.1.1 Short title ----------------- 1.1.2 Longer title which wraps onto a second line like this --------------------------- We generate the ConTeXt code from XML, so ideally a solution wouldn't require the last line to be set separately, but would just work whether the heading was single or multiple line. What I'm really looking for is a subsection setup that will automatically do this whatever length of title. I have to say I think it's quite ugly, but can anyone give me a pointer as to how it could be done? Is there a box left at the end of a par which shows the width of the last line? As I say, I've already said no, so this is just out of interest, no urgency. Thanks, Duncan

Lucida Bright Font Problem
by Helin Gai 31 Jul '06

31 Jul '06

Hi all, I'm trying to set up ConTeXt to use the Lucida Bright Font. I've already installed the font in the "LaTeX way" and it works pretty well in LaTeX. But when I use the following: \usetypescriptfile [type-buy] \loadmapfile[texnansi-bh-lucida.map] \usetypescript[lbr]%[texnansi] \setupbodyfont[lbr,11pt] The font used in the document is still computer Modern. Does ConTeXt require special setup? Any help will be greatly appreciated! Thanks! Sincerely, Colin

column overflow at times
by David Arnold 31 Jul '06

31 Jul '06

Hans, We are using: \setupcolumns [tolerance=stretch, balance=yes, blank=flexible, rule=off, distance=2.5em] However, once in a while we get column overflow. See page 55 on: http://msenux.redwoods.edu/IntAlgText/chapter0/chapter0.pdf Are we doing this correctly? Any suggestions?
