Announcement: texutil.c
by Taco Hoekwater 19 Mar '04

19 Mar '04

Hi all, Not sure if any of you consider this useful, but: I have created a C port of the perl script texutil from the ConTeXt distribution. The Makefile supports two different targets: with and without direct linking to the kpathsea path search library (default is standalone). License: GPL version 2 (for the kpathsea version), or the ConTeXt license as defined in mreadme.pdf (for the standalone version) Index key remapping and perl module plugins are not supported (both features are actually unused in the current distribution of ConTeXt). All other differences from the 'standard' texutil are bugs, and even though I give no warranty whatsoever, I would still like to know about those so that I can fix the source. (17 mar 2004, based on texutil.pl 8.2) Downloal is available from http://tex.aanhet.net/context/texutil/texutil.htm Greetings, Taco

mouseover and other advanced knowledge
by Steffen Wolfrum 19 Mar '04

19 Mar '04

Hi Hans, I'm trying to learn more about mouseover and other PDF related ConTeXt features. In an older email you recommended to look at your tug2001 demo (pre-2001.pdf). Is there also the .tex code to be read or is this your companies secret? If so, do you have some other examples to be read (as .tex files)? Thank you, Steffen

A bug in location=hanging ?
by Steffen Wolfrum 12 Mar '04

12 Mar '04

Hi, Please have a look at the example below. "\setuphanging[distance=0cm]" does not seem to have an effect at all. If I set "margin=-0.0001cm" it is almost zero, but if I set "margin=0cm" it jumps an undefined step to the right. Why can't it be zero? Did I forget a "%" at the end of some line? Thank you, Steffen ******* Example: \definelist[MyNoteList] \setuphanging[distance=0cm] \definedescription [WhatANote] [style=bold,margin=-0.0001cm,width=5cm,before=,after={\blank[5pt]},location=hanging] \def\MyNoteList#1#2#3{\startWhatANote{#1}#2\stopWhatANote} \setuplist [MyNoteList] [criterium=text, alternative=command, command=\MyNoteList] \newcounter\MyNotes \long\def\MyNote#1% {\ifhmode\unskip\fi \doglobal\increment\MyNotes\relax \high{\MyNotes}% \expanded{\writetolist[MyNoteList]{\MyNotes}}{#1}} \starttext Text \dorecurse{2}{test \MyNote{Whow, {\it another} note \input tufte }\endgraf} \page Text \placelist[MyNoteList][criterium=text] Text \stoptext

[Q]�(newbie) typesetting to grid in layer with widgets
by Rolf Marvin B e Lindgren 12 Mar '04

12 Mar '04

[firt message still waits for moderator approval, here's a new and improved version] I'm giving ConTeXt a first go in typesetting a diploma. I've figured out that I'd like to try to typeset to a five-column grid. Most of the stuff should be centered against the third column, while some stuff should be centered to the second and fourth column. This makes for a very boring diploma, but that's beside the point at this stage. I want 1-inch borders throughout, so before \starttext, I have \setuplayout[paperheight=29.97cm,paperwidth=21cm,leftmargin=1cm,rightmargin=1cm,header=1cm,footer=1cm,textwidth=19cm,textheight=27.97cm] (I pretend that marginpars don't exist. I'm sure they'll come back and haunt me). Furthermore, before \starttext, I set up the layers I think I need with \setuplayout[grid=yes,columndistance=12pt,columns=5]\showgrid \definelayer [text] \setupbackgrounds [text] [background=text] (The showgrid is there because I like to see what I'm doing). Then I have, say, \setlayer[text][column=3,line=7,x=0.5\layoutcolumnwidth,location=c]{% Diploma awarded to} now, _is_ this the smartest way to do this? furthermore, I'd like to allow for input into fields from Acrobat. I have this: \definefield[CertID][text][CertIDSetup][] \setupfield[CertIDSetup][% readonly=no,printable=yes,width=4em,% frame=on,height=8mm,offset=5ex] \myCenter{3}{11}{Sertifikat Nr. DNV-2004-OSL-PERS-\field[CertID]} trouble is, the _field_ is aligned to the baseline, whereas I'd like the text _of_ the field to be thus aligned. any suggestiosn? (as a matter of fact, the problem with this approach is that text cannot ever be centered becaue TeX need to know the dimensions at typesetting time - which isn't known until the user has interacted. is there, say, JavaScript magic that could be done in order to have text centered after it has been input? and on a sitenote, I'd like to have a frame around the entire page. Preferably, I'd like to be able to place it using numerical coordinates (absolute or relative, set to a layer or not). Is this, or something close to it, possible? thank you, -- Rolf Lindgren http://www.roffe.com/ roffe(a)tag.uio.no

linecorrection and paragraph spacing
by Nigel King 10 Mar '04

10 Mar '04

Some time ago Hans recommended the use of \startlinecorrection...\stoplinecorrection surrounding a figure. Typically I write a paragraph and then have a double carriagereturn and then a floating figure and then a double carriagereturn. The normal paragraph space does not always appear so I surround the figure by linecorrection and then find that the paragraph spacing is slightly larger than usual. Are there any rules for this. If necessary I will try to produce a minimal example although I tend to notice the problem once a document has become fairly long. TIA -- Nigel

(no subject)
by Adam Tee 09 Mar '04

Hi all, Is it possible to place some text in two columns into either the table or figure environments without the columns getting ignored. I have some data which I do not want to put in table form but require it in two columns with either a figure ot table label at the bottom. For example a c b d Table x: foo Will this have to be done manually ?? Also, I'm having some problems with using columns, what is happening is that whenever the columns finish the text afterwards runs off the end of the page. I'm using \startcolumns[n=2, tolerance=verytolerant] Thanks Adam

Hi all, We need your help in tracking down a possible bug with the Apple Preview.app when printing the Metafun manual (pdf) <http://www.pragma-ade.com/general/manuals/metafun-p.pdf> from page 37 onward. We (and Apple) would appreciate it very much if some of you would do tests on different printers and submit a report on the survey form posted at <http://latex.yauh.de/survey/survey.php?SURVEY_ID=14> Josh Carter made the original discovery and did tests on the following: ----------- HP Color LaserJet 4600dn - Printing page 1-100ish (my original print job), A4 paper scaled to letter: fuzzy pages from page 37 (physical 41) on. - Page 37 only (scaled): fuzzy. - Page 37 only (A4 cropped to letter): fuzzy. HP LaserJet 4050n: - Page 37 only (scaled): fuzzy. - Page 37 only (cropped): fuzzy. Epson Stylus Photo 2000P (note: NOT a PostScript printer): - Page 37 only (cropped): fuzzy. All were printed from my PowerBook G4/550; 512MB/30GB; MacOS X 10.3.2; latest available drivers for Color LaserJet 4600 and Epson 2000P, built-in system driver for LaserJet 4050.

Update problems: TOC
by Mari Voipio 08 Mar '04

08 Mar '04

Hello, all ConTeXters! I finally got around to trying TeXLive2003 and the ConTeXt there. The good news is that it installs into Windows2000 like a charm and all the old font woes are now past worries, the fonts worked the first try. After installing TeXLive I downloaded the newest ConTeXt from Pragma's pages and it seems to be a working installation, too. However, I have a problem to which I didn't find a solution in the mailing list archives: The Table of Contents doesn't work and that hangs the whole thing. If I get rid of the command \placecontent, everything works perfectly, but once I try to compile the file(s) with a TOC, this is what I get: myContents : - Table of contents (./pr-03.tuo ! Undefined control sequence. \exitloop ->\let \endofloop \nodoloop <argument> ...>\zeropoint \unskip \else \exitloop \fi \doloop ...@@arecurse \recursedepth \endcsname {#1 }\global \@EA \let \csname... \removeunwantedspaces ...kip \else \exitloop \fi } \fi \endstrut ...trut \fi \else \removeunwantedspaces \normalpenalty \@M \normal... <argument> ...tentry {\v!hoofdstuk }{Introduction} } ... l.7 ...1}{1}{Introduction}{2::0:1:0:0:0:0:0::1}{5} ? --- Below you'll find a simplified version of my setups etc, maybe that will help to pinpoint the problem.

reverse order sorting
by Vit Zyka 06 Mar '04

06 Mar '04

Dear Hans and ConTeXters, I go back to this question since it was not answered: > is possible to change sorting order (e.g. sort in reverse order: not A, B, C but C, B, A) in the > mechanism: > > ----- > \definesorting[address][addressbook] > \setupsorting[address][criterium=all] > \address{A} > \address{C} > \address{B} > \placelistofaddressbook > ----- I was looking for something like 'reverse=yes' in \setupsorting definition and texexec perl sort function calling, but it seemed to me, it has not been implemented yet. Am I right? I still do not have insign to setup option passing and parsing mechanism in ConTeXt macros, but who knows, the implementation might be very easy. I would need it for sorting simple scoring points. Using external (Perl or XSLT) engine ia like a hammer to mosquitos. I can solve to problem by forward sorting and TeX macro language but Perl solution is more effective. Thank you Vit Zyka

Installing 3rd-party metapost macros
by SebastianSturm＠t-online.de 05 Mar '04

05 Mar '04

Hello all, I'm still new to ConTeXt, so this might seem trivial to you... As I would like to create circuit diagrams without leaving TeXShop, I downloaded and installed the mpcirc Metapost macro package. When trying to compile, however (using \startMPinclusions input mpcirc; \stopMPinclusions), ConTeXt fails with an error message saying " TeXExec 4.0 - ConTeXt / PRAGMA ADE 1997-2003 metapost : mpgraph format : metafun This is MetaPost, Version 0.641 (Web2C 7.5.2) (/usr/local/teTeX/share/texmf.tetex/web2c/cp8bit.tcx) (mpgraph.mp (mpcirc.mp (ttex.mp) (circlib.mp >> circlib.mp >> circlib.mpx ! Unable to make mpx file. l.39 def Eplus_ = btex $+$etex enddef; Transcript written on mpgraph.log. error in metapost run : mpgraph.mp:39" Enabling \write18 and changing the MPXcommand to texexec --mptex didn't help. I would be very grateful if someone could tell me how to get mpcirc (and maybe even featpost) up and running. I'd also like to know how to enable margin kerning (I tried \setupalign[hanging], didn't work). BTW, I'm running the latest i-installer version of teTeX (including the ConTeXt updater, stable version) on OS X 10.3.2. Best regards, Sebastian

another question about itemize
by R. Ermers 04 Mar '04

04 Mar '04

Hi Contex'ers, As we are considering itemize, does anyone by any chance know how to tackle this problem? Kind regards, Robert Ermers As you know, the itemize blok can be stopped and resumed by means of [continue]: \startitemize[n] \item abc \item def \stopitemize bla bla \startitemize[continue] \item ghijk \item klmnop \stopitemize I wonder if it is possible to have an itemize block resumed, and have the numbers continue, if another set of items precedes the continuation. Like this: \starttext \section{Personalia} \startitemize[n,packed,joinedup] \item name \item surname \item place of birth \stopitemize \section{Fruits} \startitemize[A] \item appel / apple \item peer / pear \item mango \item kersen / cherries \stopitemize \section{Personalia cont.} \startitemize[n,packed,joinedup] \item Sofi-nummer / social sec. number \item Huwelijksdatum /date of marriage \item Meisjesnaam moeder / maiden name mother \stopitemize \stoptext

Problem with \startitemize
by Nikolai Weibull 04 Mar '04

04 Mar '04

I'm having a problem with \startitemize. My code is \startitemize[n,columns,four] \item $ S \rightarrow ACaB$ \item $Ca \rightarrow aaC$ \item $CB \rightarrow DB$ \item $CB \rightarrow E$ \item $aD \rightarrow Da$ \item $AD \rightarrow AC$ \item $aE \rightarrow Ea$ \item $AE \rightarrow \epsilon$ \stopitemize and for some reason the rest of the section and the next section continues of the page that the above list is rendered upon. It syncs up on the following section, but it's kind of unacceptable as you may have figured. I have not tried to find a small example that reproduces this as I figured I'd ask if this has happend anyone else before delving into a debugging session (I really don't have the time necessary), nikolai P.S. My first guess was that the math was messing it up somhow, but it fails for simple A, B, C replacements for the above \item's.

A (not so good) solution for presentations by steps
by Otared Kavian 01 Mar '04

01 Mar '04

Hi all, Sometime ago a few of us (including me) bothered Hans in order to obtain from him a step by step presentation command. He cooked up very quickly the macros contained in "s-pre-50.tex", and that was enough for most of the things. However when one uses more sophisticated styles, the overlays in "s-pre-50.tex" do not work quite good. I wrote a few macros in plain TeX and used them in ConTeXt in order to have step by step presentations with the styles "s-pre-xx.tex". (For those who know the "Prosper" macro packages for LaTeX, I got actually my inspiration from "prosper"). I admit that someone can write better and more elegant macros using the hidden power of ConTeXt, but at this point I am unable to do this... So could anyone try the following macros and tell if the steps are satisfactory for them? Thanks: Otared K. %%%% Beginning of the macros %%K s-pre-steps.tex %%K %%K Here we use the plain \TeX\ command \phantom{} in order to have %%K some material appear step by step. %%K The structure is quite simple, but since I am not very %%K familiar with ConTeXt, I cannot write elegant code as does %%K Hans Hagen... %%K %%K An advantage is that the code can be used also in %%K plain TeX, in LaTeX and other macro-packages. %%K %%K Otared Kavian <otared.kavian(a)wanadoo.fr> %%K last modified March 1, 2004 %%K \newif\ifSteppingSlide \SteppingSlidetrue %%K this is when you want a step by step presentation %\SteppingSlidefalse %%K this is when you want to print the slides % \newcount\StepsCounter \StepsCounter=0 % \newcount\NumberOfSteps \NumberOfSteps=10 % \newcount\BeforeStepNumber \BeforeStepNumber=0 % %%K StepBetween[number1,number2]{material} will make "material" %%K appear between steps "number1" and "number2" \def\StepBetween[#1,#2]#3{% \ifSteppingSlide \ifnum#1>\StepsCounter \phantom{#3} \else \ifnum#2<\StepsCounter \phantom{#3} \else \relax #3 \fi \fi \else {#3} \fi} % %%K Step{number}{material} will make "material" %%K appear beginning with step "number" until "NumberOfSteps" \def\Step#1#2{\StepBetween[#1,\NumberOfSteps]{#2}} % %%K OnlyStep{number}{material} will make "material" %%K appear only on step "number" \def\OnlyStep#1#2{\StepBetween[#1,#1]{#2}} % %%K StepBefore{number}{material} will make "material" %%K appear only on all steps before "number" \def\StepBefore#1#2{ \global\BeforeStepNumber=#1\global\advance\BeforeStepNumber by -1 \StepBetween[0,\BeforeStepNumber]{#2}} % \long\def\SlideWithSteps#1#2{ \ifSteppingSlide \global\StepsCounter=0 \global\NumberOfSteps=#1 \MakeSteps{#2} \else #2 \fi} % \long\def\MakeSteps#1{\loop #1 \ifnum\StepsCounter<\NumberOfSteps \global\advance\StepsCounter by 1\vfill\eject \repeat \vfill\eject} % %%K This is the end of the macros %%K End of the macros "s-pre-steps.tex" %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% %%K Here is an example to test the above macros % \input s-pre-steps.tex \usemodule[pre-general] %%K I tried the macros for step by step presentation %%K with the following styles: \input s-pre-04.tex %\input s-pre-09.tex %\input s-pre-16.tex %\input s-pre-19.tex %\setupbodyfont[ss, 14.4pt] %% because I can't use other fonts %% due to a local problem on my Mac OS X, I guess \starttext \TitlePage {A simple presentation} \Topics {Today's talk} \Topic {First item} \input knuth \Topic {Second item} \input tufte \Subject {A subitem} \input knuth \Subject {Another subitem} \input tufte \Subject {Here are some steps} In the next slide we show some material appearing step by step.
