External figures in section headings
by Felix Ingram 09 Jan '11

09 Jan '11

Hello all, I need to have an image as part of my section headings. I've read through an example in the "It's in the details" manual and came up with the following example: \definelayer[chapterstart][width=\paperwidth,height=\paperheight] \definelayerpreset[lefttop][corner={left,top},location={right,bottom}] \setlayer[chapterstart][preset=lefttop]{\externalfigure[hacker.jpg]} \setuphead[chapter][before={\setupbackgrounds[page][background=chapterstart]}] \starttext \chapter{First chapter} \chapter{Second chapter} \stoptext This works very well for the first chapter: the picture is inserted behind the text as I want but nothing is inserted behind the second chapter heading. I've been able to add extra details to the setuphead; these are repeated but the picture is not. Can anyone see what I'm doing wrong? I get the same behaviour whether I use version II or IV. Many thanks in advance, Felix

Passing and retrieveing a variable
by Procházka Lukáš 09 Jan '11

09 Jan '11

Hello, I'd need to pass a variable to Ctx and to retrieve it inside a compiled document - via Ctx itself and also by Lua. Something like modes; but modes allow just to check whether they are on or off. I'd need something like this: Calling context.exe: --- call context.exe test.mkiv --mode:MyMode --variable MyVariable=AAA --- And test.mkiv: --- \starttext Hello \doifmode{MyMode}{Being in MyMode} \ifvariableequal{MyVariable}{AAA}{MyVariable is \MyVariable} % Something like this \startluacode if context.variables.MyVariable == "AAA" then context("MyVariable is defined.") -- Something like this end \stopluacode \stoptext --- Simply said, I'd need to provide a conditional (or: dependent) compilation of the input file. How to handle this? Best regards, Lukas

Natural tables (split) + setupinteraction = fail? (latest mkiv)
by Marco Pessotto 09 Jan '11

Hello there. See the following minimal example: %%%% begin %%%% \setupinteraction[state=start,color=black,contrastcolor=black] \starttext \placetable[split]{Test} {\bTABLE[split=yes] \dorecurse{60}{ \bTR \bTD hello \eTD \eTR } \eTABLE} \stoptext %%%% end %%%%% If I try to compile it, I get the following error: pages > flushing realpage 1, userpage 1, subpage 1 ! Missing number, treated as zero. <to be read again> { \docompletefloat ...\vbox \floatcaptionattribute { \doifelsemainfloatbody \cu... <argument> ...loat {table}{}{split}{Test}\nextbox \else \docompletefloat {ta... \thirdofthreearguments #1#2#3->#3 \xdocompletefloat ...afloat ,#3}{#4}\nextbox \fi } \else \docompletefloat {#1... \dodowithnextbox ...tefloat {table}{}{split}{Test} \doifnotinset \v!text {spl... ... l.11 \eTABLE } ? The same source compiles as expected with version 2010.12.15 (ok, there was the bug for the numbering, but it compiled). Bests -- Marco

I can easily get ♪ just by copy-pasting, but I cannot get ♩ ! Even when the font is specified. When I paste ♩ symbol into TeXWorks, it disappears. That's why I want how to call it by name. -- Best Regards, Vyatcheslav Yatskovsky

How to invoke Unicode symbols?
by Vyatcheslav Yatskovsky 09 Jan '11

09 Jan '11

Hi, How to invoke pre-defined Unicode symbols? E.g., in "symb-uni.tex" I see \startsymbolset[Unicode Musical] % 0x2600: Requires UnicodeRegular26 \definesymbol[QuarterNote][\USymbChar{38}{105}] % QUARTER NOTE \definesymbol[EighthNote][\USymbChar{38}{106}] % EIGHTH NOTE ... \symbol[QuarterNote] gives me words "QuarterNote", and \QuarterNote is an invalid sequence. P.S. http://wiki.contextgarden.net/Reference/en/symbol is empty :( -- Best Regards, Vyatcheslav Yatskovsky
