Unreadable characters in embedded PDF file
by Jaroslav Hajtmar 10 Jan '11

10 Jan '11

Hello all, Often I include external PDF files into PDF document generated by ConTeXt. When I create a PDF document containing text in Scribus (or other application) and then I put it to my PDF file (generating by ConTeXt), then in final PDF document are unreadable characters. Is there a problem in Scribus character encoding or the fact that the fonts contained in the included PDF file ConTeXt unknown? Thanks for the advice. Jaroslav

Math delimiters too big in lucida in MKII
by Yue Wang 10 Jan '11

10 Jan '11

Hi, Hans: I dont know why you do this in math-lbr.mkii: \def\LBRbig {\@@dobig{8.20}} \def\LBRBig {\@@dobig{10.80}} \def\LBRbigg {\@@dobig{13.42}} \def\LBRBigg {\@@dobig{16.03}} \def\LBRbiggg{\@@dobig{17.72}} \def\LBRBiggg{\@@dobig{21.25}} % \def\LBRbig {\@@dobig{0.820}} % \def\LBRBig {\@@dobig{1.080}} % \def\LBRbigg {\@@dobig{1.342}} % \def\LBRBigg {\@@dobig{1.603}} % \def\LBRbiggg{\@@dobig{1.772}} % \def\LBRBiggg{\@@dobig{2.125}} I think the second set of parameters( the commented one) is correct. or \big,\bigg, etc will produce huge delimiters...

handling key=value sets with lua
by Philipp A. 09 Jan '11

09 Jan '11

hi list, skip to the many %%% if you just want to help me ;) i need to make a macro which consists of ten optional arguments. it wouldn’t be too ugly to require to write the following to use it, since it outputs a 3×3 matrix with an adjacent tenth item, but tex can’t handle ten arguments afaik. syntax idea: empty: \bigcrafting% {}{}{}% {}{}{}{}% {}{}{}% partly filled: \bigcrafting% {}{}{}% {planks}{planks}{}{workbench}% {planks}{planks}{}% how it should look: [image: CraftingWorkbenchIO.png] ok, since using empty “required” arguments aren’t elegent, either, i wanted to get into key=value sets, but ran into the next problem: i wanted to instead define bigcrafting to work like this: \bigcrafting [21=planks, 22=planks, 31=planks, 32=planks] [workbench] but \getparameters<http://wiki.contextgarden.net/Commands_with_KeyVal_arguments>can’t handle numerical values. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% and while points of the compass like NE, S and C (for center) would work, it sprang to my mind that a parser written in lua, whitch uses lua’s internal hashtables would meet my furter needs better (like looping over the matrix and testing if parameters are set) can somebody tell my how to access (and test if they exist) the arguments (#1,[#2],…) of a command definition in lua?

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

Hello there.

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
