Table of Contents Spacing
by Troy Henderson 29 Jan '13

29 Jan '13

How do I change the vertical spacing between chapter/section list items in the Table of Contents? It appears that the spacing between chapter items is about 2ex (or so) and perhaps 1ex (or so) between section items. Troy

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]
by Henning Hraban Ramm 29 Jan '13

29 Jan '13

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

Some more question, ex "Context an excursion"
by Alain Delmotte 27 Jan '13

27 Jan '13

Hi, Using MkIV and the latest(?) standalone version. Continuing "Context an excursion"! Thanks for your help, Alain 1) How to force line jump to avoid overfull \hbox, particularly with more or less narrow columns? 2) I did insert \showlayout just before \stoptext and I get 4 pages with the same information!!! 3) On page 77, I get an error: \defineparagraphs[city][n=2,before=,after=] \city Hasselt (Ov) \\ Overijssel \\ \city Hasselt (Li) \\ Limburg \\ \startpacked \city Hasselt (Ov) \\ The Netherlands \\ \city Hasselt (Li) \\ Belgium \\ \stoppacked ------------------error message ! Undefined control sequence. system > tex > error on line 868 in file travail.tex: Undefined control sequence ... 858 \blank 859 The affix is a leftover from the times that the Netherlands and 860 Belgium were one country under the reign of King Philip II of Spain. 861 \blank[2*big] 862 Hasselt in Belgium lies in the province of Limburg.

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.)

Footnotes numbering
by Willi Egger 27 Jan '13

27 Jan '13

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
