Consistent Colors
by Devendra Ghate 29 Jan '13

29 Jan '13

I have been going through the concepts underlying pallet. I would like to define three basic colors in RGB. Then use various shades and tints of these basic three colors through out the document. Now the algorithm for getting various shades for RGB scheme is: Darker shades: Multiply each component by 1/4, 1/2, 3/4, etc. of its previous value, depending on how dark the color should be. Lighter tints: Calculate (1 - previous value), multiply that by 1/4, 1/2, 3/4, etc. and add that to the previous value. What I would like is a macro that is fed a color name and should define 3 shades above and below it. I have following problems: 1. How to get RGB values of an already defined color? If this is too involved then I can pass the RGB values to the macro as well. 2. How to create a loop and carry out the above arithmatic to create RGB values for various shades? Essentially the problem boils down to doing arithmetic calculations and creating loops in ConTeXt. Regards, Devendra MWE: -------------------------- \setupcolor[rgb] \definecolor[maroon][r=0.8, g=0.2, b=0.4] %\definecolorgroup %[maroon][rgb] %[0.9:0.6:0.7, %0.8:0.2:0.4, %0.4:0.1:0.2, %0.2:0.05:0.1] % A macro that generates three shades above and below the given color. % It is assumed here that the RGB values are also passed along with % the color name. \define[4]\generateColorGroup{ \definecolorgroup [#1] [#2:#3:#4] %\dimexpr#2/4:#3/4:#4/4] }% \generateColorGroup{maroon}{0.8}{0.2}{0.4} \starttext \showcolor \stoptext -------------------------------

arranging vs. \page[last]

latest beta of ConTeXt MkIv standalone If I use \page[last] with arranging, ConTeXt inserts additional pages and the page that’s meant to be last is not: \setuppapersize[A5][A4,landscape] \setuparranging[2UP] \starttext \chapter{One} \input tufte \chapter{Two} \input tufte \page[last] \chapter{Last} \input tufte \stoptext (Workaround: make a not-arranged PDF and arrange \copypages) Greetlings, Hraban --- http://www.fiee.net/texnique/ http://wiki.contextgarden.net https://www.cacert.org (I'm an assurer)

Coming back to ConTeXt
by Alain Delmotte 28 Jan '13

28 Jan '13

Hi, I decided to give another try to ConTeXt. I already did two years ago, I think, but I had problems mostly because of the lack of documentation for MkIV. Having a more or less strong knowledge and experience of LaTeX doesn't help!!! This time: I did not succeed to install a stand alone version. I have also TeX Live and I need it for LaTeX. I am using TeXworks (not the one from TeX Live). I use ConTeX from TeX Live 2012: This is LuaTeX, Version beta-0.70.2-2012080612 (TeX Live 2012/W32TeX) ConTeXt ver: 2012.05.30 11:26 MKIV fmt: 2013.1.20 int: english/english Following the discussions on ntg-context, there often is solution using one of hte latest version of ConTeXt, so I have a first question: is it possible to update the TeX Live ConTeXt and its associated files? I also have questions about typography (hyphenation, typographic rules,...) to have something according the French rules, and others... Other questions in another message. Thanks for your help, Alain Delmotte

Creating a folded meander book - imposition problem
by Mari Voipio 27 Jan '13

27 Jan '13

I would love to create a folded meander book, but as far as I can see, that means creating a new imposition scheme and that's beyond my skill. What I want is a cross between 2*16 and x=4, y=4 (I think). Here's an explanation and a nice graphic of a 16-page (4x4) meander book: http://stamphenge.wordpress.com/minibooks/meander-accordion-folded-book/ A 9-page version (3x3) would also be nice to have, to make slightly bigger pages when printed on A4. Thank you, Mari (Slowly brewing: an article on using ConTeXt and MetaPost in papercrafts.)

Hi all, Is among you somebody who has used text with footnotes, where the footnotes would be numbered according to the line number where the reference resides? In other words how to use line numbers for the numbering of the footnotes? Any hint would be great! Kind regards Willi

PDF Bookmarks
by Troy Henderson 27 Jan '13

27 Jan '13

I would like to create PDF bookmarks in my ConTeXt document, but I do not want my document arranged in "normal" chapter/sections. I know that I can do \setupinteraction[state=start] \placebookmarks[chapter,section,subsection][chapter,section] \setupinteractionscreen[option=bookmark] and then in my document I can do \chapter{Foo} In this case, my PDF bookmark appears as "1 Foo". Furthermore, in the document itself, the chapter heading shows as "1 Foo". I would like the bookmark to just appear as "Foo" and I do not want ANY chapter/section headings when I issue the \chapter{Foo} or \section{Bar} commands. That is, in the document, I would like those commands to basically JUST create the bookmarks and have the bookmarks omit the chapter/section number. Troy

Some questions
by Alain Delmotte 26 Jan '13

26 Jan '13

Hi, Now some questions to solve the problems I have when I try to follow the "tutorial" "ConTeXt an excursion". I think it is for mkII and I use mkIV and that there has been many changes in between. - The example at the bottom of page 11 and page 12 gives me an error: ! Argument of \head has an extra }. system > tex > error on line 52 in file travail.tex: Argument of ... 42 Hasselt lies in the province of Overijssel and there are a number of customs that are typical of this province. 43 \startitemize 44 \head kraamschudden \hfill (child welcoming) 45 When a child is born the neighbours come to visit the new parents. The women come to admire the baby and the men come to judge the baby (if it is a boy) if he will become a strong man. 46 The neighbours will bring a {\em krentenwegge} along. A krentenwegge is a loaf of currant bread of about 1 \Meter\ long. Of course the birth is celebrated with {\em jenever}. 47 \head nabuurschap (naberschop) \hfill (neighbourship) 48 Smaller communities used to be very dependent on the cooperation among the members for their well being. Members of the {\em nabuurschap} helped each other in difficult times during harvest times, funerals or any hardship that fell upon the community. 49 \head Abraham \& Sarah \hfill (identical) 50 When people turn 50 in Hasselt it is said that they see Abraham or Sarah. The custom is to give these people a {\em speculaas} Abraham or a Sarah. Speculaas is a kind of hard spiced biscuit. 51 \stopitemize 52 >> - The tables pages 30-31-32-35 are not at the right position on the page, mostly they are to the right and not centered. - The chemical formulae give an error (pages 37-38), but I'll come back to that later on, but what is the manual about it? - The boxes on page 45, second example are not at the right position, particularly the second is on the same line as the first. \leftaligned {\inframed[width=fit]{People in Hasselt}} \midaligned {\inframed[height=1.5cm,frame=off]{have a}} \rightaligned {\inframed[background=screen]{historic background}} What are the up todate manuals for MkIV? OK It's enough bothering you for the moment. Thanks in advance, Alain Delmotte

Hello ConTeXist. I use the \processcommalist command and at this point I would like to see if there is any possibility of using a similar command but with the custom separator. Not to me to use a comma as a separator, because I need to have a comma as a character in the processed item list.

Paragraph indentation after float
by Marco Patzer 23 Jan '13

23 Jan '13

Hi, sometimes I get a paragraph indentation after a float and sometimes I don't. Example: \ctxlua{structures.lists.autoreorder = true} \setupindenting [yes, medium] \setupfloats [default=auto] \starttext \startchapter [title=Foo] \startplacefigure \externalfigure [cow] %% [height=21cm] \stopplacefigure \startplacefigure \externalfigure [cow] [height=11cm] \stopplacefigure \input knuth \stopchapter \stoptext Why does this chapter start with an indentation? I always avoid placing floats at the beginning of sections, since I can never predict what will happen. If the first float is moved to the second page (uncomment height=21cm) the indentation vanishes. Why? Is there a reliable way to place floats at the beginning of sections and ensure that the following paragraph will not be indented? Marco

Bug in reference to sections

Hi Hans, I noticed that with the latest mkiv (version 2013.01.22 18:33 MKIV fmt: 2013.1.22) when the sections have no numbers two « ! » are printed and this behavior is new: with previous versions when invoking for instance \in{other section}[sec:other] there used to be a link to the "other section" and no « ! ! ». I understand that there has been a change in this behavior, but is there a way to suppress the two « ! ! »?
