Weird texexec hang
by nico 19 May '06

19 May '06

Hello, I took me quite some time to extract the following sequence from a 300p book, that makes the compilation hang. It looks like if it's in an infinite loop, but I don't know what happens. It seems related to the interaction of float, verbatim, and background stuff. I thought it was a local resource problem (few memory on my machine) but trying the code in live context never gave something either (i hope it is not still running!). What's wrong in my definitions/setups to have such a behaviour? \setuplayout[middle] \setupcolors[state=start] \setupinteraction[state=start] \definefloat[dbsidebar] \setupfloat [dbsidebar] [criterium=0.7\textwidth, leftmargindistance=-\outercombitotal, rightmargindistance=-\outercombitotal, default={outer,middle}] \setupcaption[dbsidebar][location=bottom,number=no] \defineframedtext [framesidebar] [width=.9\textwidth,bodyfont=small, corner=round,background=screen,backgroundscreen=.95] \setupbackground [background=screen, frame=on, strut=yes, topoffset=2mm, width=broad, before=\blank, after={\blank[small]}, align=right] % Verbatim environment for programlisting \definetyping[code] \setuptyping[code] [bodyfont=small, before={\startbackground}, after={\stopbackground}] \starttext \input tufte \input tufte \placedbsidebar{joke} {\startframesidebar \startcode some code \stopcode \stopframesidebar} \input tufte \input tufte \placedbsidebar{joke} {\startframesidebar \startcode some code \stopcode \stopframesidebar} \stoptext Regards, BG

definitions local to a component
by Sanjoy Mahajan 18 May '06

What's the safe way to make \def's local to a component? I could wrap each component in a \begingroup..\endgroup but that might do bad things to the output routine. -Sanjoy `Never underestimate the evil of which men of power are capable.' --Bertrand Russell, _War Crimes in Vietnam_, chapter 1.

When I regenerate the formats on my linux box with the latest release, I get this error: language : patterns pl for pl loaded (n=13,e=pl0,m=pl0) (/usr/share/texmf/tex/generic/hyphen/plhyph.tex !Improper alphabetic constant. <to be read again> \else \utffouruniglph ...tf@c *(#1-\utf@f )+\utf@b *(`#2 -\utf@g )+\utf@a *(`#3-\ut... l.189 ./sr/o 2d5 Since nobody else complains, I guess this must be a misconfiguration on my side, but what could it be?

Wrong image size evaluation
by nico 18 May '06

18 May '06

Hello, I have some troubles with a PNG image, that is not correctly rendered by context (too small). The difference I've found with another correctly displayed image is that the file does not contain any resolution unit (but a pixels/inch default seems reasonable). Is there a workaround or specific setup to make this work (without explicit width setting)? Here is the test file I use. If you wish I can send the images, or find the troublesome PNG image at: http://svnbook.red-bean.com/trac/browser/trunk/src/en/book/images/ch01dia1.… Thanks for your help. \starttext \startyping identify -verbose images/ch02dia1.png images/ch02dia1.png PNG 146x168 146x168+0+0 PseudoClass 135c 2kb 0.008u 0:01 Image: images/ch02dia1.png Format: PNG (Portable Network Graphics) Geometry: 146x168 Resolution: 28.34x28.34 Units: PixelsPerCentimeter \stoptyping \externalfigure[images/ch02dia1.png] \startyping identify -verbose images/ch01dia1.png images/ch01dia1.png PNG 511x585 511x585+0+0 DirectClass 54kb 0.094u 0:01 Image: images/ch01dia1.png Format: PNG (Portable Network Graphics) Geometry: 511x585 Resolution: 72x72 Units: Undefined \stoptyping \externalfigure[images/ch01dia1.png] \stoptext Regards, BG

Dense encoding, part II ???
by Mojca Miklavec 18 May '06

18 May '06

Hello, on the [tex-fonts] mailing list there was a recent discussion of people putting effort into enabling proper encoding to support typesetting of Lithuanian (in LaTeX). Before they start creating and using yet another encoding (incompatible with others and not shipped with any standard TeX distribution): is there any chance to finish the companion encoding in some reasonable time? Even if they keep using LaTeX, I think that the same mechanism can be used in LaTeX as the one which combined EC (T1) with TS1. There is probably not that much left to be done. The letter part of the encoding is finished (and the Polish fonts already ship with those metric files) and quite some ideas for the companion font are already there. The major part left is to create ConTeXt support for combining two encodings, but from the past experiance with Hans that is probably a matter of not even a couple of hours. Or should we wait for Oriental TeX first? Mojca

vertically centered aligment of different sized texts
by frantisek holop 18 May '06

18 May '06

hi there, another question to which shamefully i cannot find the answer. perhaps it's just too late... consider the following example: \definefont[BigFont][Regular sa 3] \starttext {\tfc The {\BigFont 7}\high{th} Seal} \stoptext how can i make that line vertically centered, like --, the /th seal / :) is \startalignment used for this? -f -- every great journey begins with a single step.

More Feature Requests for math
by Aditya Mahajan 18 May '06

18 May '06

Hi Hans, Can you provide some more features to \definematrix and \definemathcases. 1. Allow \definematrix and \definemathcases to have a parameter displaystyle or textstyle. Right now, everything is in textstyle. Consider \startformula a = \startcases \NC E = mc^2 \NC nothing interesting to see here \NR \NC \int_0^1 x - 3 d\,x \NC Integral is in text mode \NR \stopcases \stopformula \startformula \startmatrix[n=2] \NC x \NC y \NR \NC \int_0^1 x - 3 d\,x \NC 20 \NR \stopmatrix \stopformula Both integrals are in textstyle. It will be nice if one had a configuration like \definemathcases[displaycases][displaystyle] and \definemathmatrix[displaymatrix][displaystyle] so that \startdisplaymatrix \NC a \NC b \NR \NC d \NC e \NR \stopdisplaymatrix is equivalent to \startmatrix \NC \displaystyle a \NC \displaystyle b \NR \NC \displaystyle d \NC \displaystyle e \NR \stopmatrix and similar for startdisplaycases. I don't know which syntax is better displaystyle=on|off (yes|no) or [mathstyle=display|text]. 2. Allow location=top|center|bottom for \definemathmatrix. Right now, inside \dostartmathmatrix there is a \vcenter. Can this be changed to \vtop or \vbottom depending on the value of location. With these features, it will be straightforward to emulate the behaviour of aligned and gathered environments of amsmath. 3. Can pagebreak inside \startalign be restored. This used to work, but broke while ensuring compatibility with \setupformulas[align=??] \placeformula \startformula \startalign \dorecurse{50} { \NC a \EQ b \NR[+] } \stopalign \stopformula Thanks, Aditya -- Aditya Mahajan, EECS Systems, University of Michigan http://www.eecs.umich.edu/~adityam || Ph: 7342624008

First hack at new ruby-aware texexec script for linux/unix
by gnwiii＠gmail.com 18 May '06

18 May '06

There are two classes of users: 1) most error messages are ignored up to and including the ones that promise global thermonuclear war if you click on "Yes", or 2) minor warnings bring all work to a halt until explained. In honor of the latter class, who ask about the suggestion to use "texstart texexec.rb ..." when running context, the following script may be helpful. TeX Live on linux runs texexec, etc. via a shell script that is linked to the names of various perl utilities. Here is my first cut at a version that tries to use the ruby scripts: ------------------------------------------------------------------ #!/bin/sh # use ruby and texmfstart.rb or perl # to use: link to the names of ConTeXt scripts what=`echo $0 | sed 's@.*/@@'` case $what in texmfstart|texexec|pstopdf|textools|texutil) p=`kpsewhich -format=texmfscripts $what.rb` { test -n "$p" && test -f "$p"; } \ || { echo "\`$what.rb' not found."; exit 1; } RUBYLIB="${RUBYLIB:-${p%/*}}" export RUBYLIB exec ruby "$p" ${1+"$@"} ;; *) p=`kpsewhich -format=texmfscripts $what.pl` { test -n "$p" && test -f "$p"; } \ || { echo "\`$what.pl' not found."; exit 1; } exec perl "$p" ${1+"$@"} ;; esac ------------------------------------------------------- This version runs the ruby scripts directly, rather than the suggested form, e.g., "texfmstart pstopdf.rb file.ps". I have no idea if that is intended to work -- it did in my very simple tests . I'm not sure the RUBYLIB line is needed. -- George N.

The line in scripts/context/ruby/graphics/gs.rb with -dSAFER needs a <space> before the closing quote. The corrected line is: arguments << "-q -sDEVICE=pdfwrite -dNOPAUSE -dNOCACHE -dBATCH -dSAFER " -- George N. White III <aa056(a)chebucto.ns.ca> Head of St. Margarets Bay, Nova Scotia
