LaTeX array equivalence with multiline \lbrace
by Renaud AUBIN 27 Jan '06

27 Jan '06

Hi all, With LaTeX, I have $$ \left\lbrace \begin{array}{l} \dot{q}_i = 1 \quad\text{ if } i=k \\ \dot{q}_i = 0 \quad\text{ else} \end{array} \right $$ How to do this within a ConTeXt document ?

itemize[loose]
by Hans van der Meer 27 Jan '06

27 Jan '06

When typesetting an enumeration with a specified item text I encountered an error with the combination of [loose] with \sym{} and \mar{}. The hope was that "loose" will allow underfull filling of the lines without complaint (I don't like TeX complaining) An example follows: \starttext \setupitemize[loose] \startitemize \sym {xyz} 12345 \stopitemize \stoptext Error message: ! Undefined control sequence. <argument> \optimizeitemsfalse \p!compareprocessaction ...commalistelement {#3}#2 \expandafter \quitcommalis... etc. Is this expected behaviour? The manual does not give me an idea about that. yours sincerely, dr. H. van der Meer

SVG images
by Ville Voipio 26 Jan '06

26 Jan '06

I would need to embed some SVG images into a ConTeXt document. I have done some research on the topic, and the seemingly trivial task seems all but impossible. I found a few solutions, but none of them fits my needs: - I want to have my vector images in vector format (i.e., no Inkscape-to-PNG) - alpha-channel transparency is used in the images, and it should be present in the PDF file, as well (i.e., no Inkscape-to-EPS) - if I used commercial products, I would not use SVG (i.e., the converter should be open source) The images have been (will be) created with Inkscape. While being otherwise a surprisingly nice piece of software, Inkscape does not seem to export PDF for some reason or another (licencing, time, etc.). I have the impression I just ran out of luck. Did I? - Ville

color in before=
by Hans van der Meer 26 Jan '06

26 Jan '06

I want to put a color command in a "before" command, that command being inserted in a macro. Something like \setupxyz[before=\color[green]{whatever}] The problem is that the argument parser gets confused when []- expressions are found within the setup. It is not an option to reprogram everything with {}'s instead of []'s, because then I lose to much of ConTeXt's abilities (apart from the nuisance of having to reprogram something that has already been done). I suspect there is no way of sneaking in these []'s inside the command? That is the general solution. My eyes spotted something like \dowithcolor#1#2, but there TeX complains about not knowing \od. Is there a solution to this problem? yours sincerely, dr. H. van der Meer

lines and tables
by p.broschwitz＠freenet.de 26 Jan '06

26 Jan '06

Hi Forum, I need a little help to create lines and tables. I would like to positioning lines and tables exactly. So I think I must work with layers! Is it right? And could anybody show me an example for creating these lines and tables? Thanks very much!

embedding multipage pdf
by andrea valle 25 Jan '06

25 Jan '06

Hi to all, I'm preparing a (standard) musical score. I've scored the music with lilypond and I have as output an A3 pdf of many pages. My idea was to create the cover and the other information pages surrounding the music with Context. In fact, I happily prepared my A3 context pages and I was trying to include the music pdf in the resulting tex file . I simply put my pdf in \externalfigure: it works, but only for first page. How do I include all the pdf? I can solve printing the pages from the context and lilypond output files, and then gluing the resulting paper, but I'd like to have an integrated source file to be printed. Thanks a lot -a- Andrea Valle DAMS - Facoltà di Scienze della Formazione Università degli Studi di Torino http://www.semiotiche.it/andrea andrea.valle(a)unito.it

strange \v!on
by Hans van der Meer 25 Jan '06

25 Jan '06

Encountered something strange setting up the parameters of framed. This runs normal: \setupframed[frame=off,strut=\v!no, ... This gives an error: \setupframed[frame=\v!off,strut=\v!no, ... The same happens with \v!on as parameter. The difference is "off" vs. "\v!off" (of course running within \unprotect .. \protect pair). It seems to go wrong at the "frame" parameter only, because for example strut accepts \v!no. Is there perhaps a clash with another macro? I get this in the console (TeXShop): ! Missing \endcsname inserted. <to be read again> \let \dobuildtextaccent #1#2->{\let \char \normalaccent #1\let \char \normalchar #2} \dohandleaccent ...acterencoding #1\endcsname {#2} \fi \fi \fi \@@oiframe ->\v ! on <argument> t\@@frame@@ \framedparameter \c!frame \framedparameter \c! topframe \getvalue #1->\csname #1 \endcsname ... l.44 \stoptable }{first table} ? Process aborted yours sincerely, dr. H. van der Meer

Dropped caps, \startlines\stoplines, and indentation question
by Adrian Drury 25 Jan '06

25 Jan '06

Hello, I'm having trouble using dropped caps within \startlines\stoplines. I'm trying to typeset some poetry and I'm using \setuplines[space=yes]. I'd like to use dropped caps and have the indented lines be additionally indented by any space at the beginning of the lines. See the following example - the first part shows roughly the result I want (but with manual formatting/spacing), the second part shows the result of \DroppedCaps inside \startlines\stoplines, and the third part uses the lettrine module. The lettrine module comes close, but Nindent doesn't seem to affect the indented lines within \startlines\stoplines. \usemodule[lettrine] \def\MyDroppedCaps% { \DroppedCaps {} {Serif} {2\baselineskip} {2pt} {1\baselineskip} {2} } \setuplines[space=yes] \starttext \MyDroppedCaps S{\sc umer} is icumen in,\crlf \hbox to .6em{}Lhude sing cuccu!\crlf Groweth sed, and bloweth med,\crlf \hbox to .6em{}And springth the wude nu---\crlf \hbox to 3.3em{}Sing cuccu! \startlines \MyDroppedCaps S{\sc umer} is icumen in, Lhude sing cuccu! Groweth sed, and bloweth med, And springth the wude nu--- Sing cuccu! \stoplines \startlines \lettrine{S}{umer} is icumen in, Lhude sing cuccu! Groweth sed, and bloweth med, And springth the wude nu--- Sing cuccu! \stoplines \stoptext Any suggestions for how to do this? I'm a beginning ConTeXt user, so if there's a better/different way to do this, I'd be happy to hear it! Also, I read the list in digest form. For the benefit of people using threaded mail readers, is there a better way to reply to individual messages than replying to the digest message and editing the Subject line appropriately? Thanks very much, Adrian Drury

formula in itemlist
by Hans van der Meer 25 Jan '06

25 Jan '06

I want to place a math formula in the item of an itemlist, but I keep getting overfull hboxes. A minimal example follows: \starttext \startitemize \item dit is een \item dit is een formule \placeformula[-] \startformula n= 0 % this is line 7 \stopformula \stopitemize \stoptext in the log it says: Overfull \hbox (17.62474pt too wide) in paragraph at lines 7--7 [][] \hbox(10.41603+4.05064)x0.0 .\glue(\leftskip) 17.62474 .\hbox(0.0+0.0)x0.0 .\hbox(10.41603+4.05064)x0.0 ..\rule(10.41603+4.05064)x0.0 ..\glue 0.0 plus 1.0fil minus 1.0fil .\penalty 10000 .\glue(\parfillskip) 0.0 plus 1.0fil .etc. Removing the "\placeformula" makes no difference. Although a fallback to $$ n = 0 $$ makes the overfull hbox go away, it does not seem the "ConTeXt" way of doing. Is this something in formula about not changing a hbox-width inside the itemize? yours sincerely, dr. H. van der Meer
