Multiplication table (with lines) in ConTeXt?
by Alasdair McAndrew 04 May '11

04 May '11

I want to typeset a multiplication table, where there will be a horizontal line after the first row, and a vertical line after the first column. In LaTeX, I can use: \[ \begin{array}{c|ccccccc} \times&0&1&2&3&4&5&6\\ \hline 0&0&0&0&0&0&0&0\\ 1&0&1&2&3&4&5&6\\ 2&0&2&4&6&1&3&5\\ 3&0&3&6&2&5&1&4\\ 4&0&4&1&5&2&6&3\\ 5&0&5&3&1&6&4&2\\ 6&0&6&5&4&3&2&1 \end{array} \] What is the canonical way of including lines in a mathematical array in ConTeXt? Thanks, Alasdair

Bibliography question: one list of references per chapter and one overall list
by Renald Buter 04 May '11

04 May '11

Hello all, I am currently making up my thesis in ConTeXt. And I am thoroughly impressed with the professional looking result I already have, although I have only recently started using ConTeXt. Now, I have a question regarding reference lists: I would like to have one list per chapter (which are original research papers), but also one big list at the end of the thesis, as a separate chapter, containing all unique references in whole thesis. At the moment, I'm using the bib module. This works perfectly if I compile every single chapter separately (i.e. 'texexec chapter01.tex', for example). However, if I compile the whole component (i.e. 'texexec thesis.tex'), I obviously get at every chapter the same reference list, regardless whether the references were cited in that particular chapter. Does anyone have suggestions on how to accomplish this (if at all possible)? With kind regards, Renald

modules or packages for abbreviations for common math commands
by Paul Menzel 04 May '11

04 May '11

Dear ConTeXt folks, is there a module or a package people have created for common things used in mathematics. `\set{ a, b, c }` for a set. `\EV{X}` for the expected value. `\P{ X = ½ }` for the probability. … If not, maybe a module could be created and maintained together to not reinvent the wheel. Thanks, Paul

Re: [NTG-context] Too much spacing in math mode between 'f' and 'l' (MkIV only)
by S Barmeier 04 May '11

Is it a bug? > Spacing between letters when treated as individual variables is always a bit fishy. In this case the math mode suppresses the fl ligature, which seems to be present in the font, whence the spacing is off. Something like \starttext \math{{\it flow}_1} \stoptext will help ConTeXt treat it as text and improve the spacing (and in this case make use of the fl ligature). Define \def\flow{\text{\it flow}} if you just want to say \starttext \math{\flow_1} \stoptext Severin

tikz picture is placed align left-upper corner
by Gao Ya'nan 03 May '11

03 May '11

I draw a figure by tikz but found it is not in the middle but a little left of the page, and then I wrote a piece code and impoved my view. And I tried to add some parameters to put the figure in the middle but failed. Thanks for any tips and test code is below. \usemodule[tikz] \usetikzlibrary[positioning, shapes, shadows, arrows] \usetikzlibrary[backgrounds] \starttext \placefigure[here][fig:pci]{PCI System}{ \framed{ \hbox{ \tikzstyle{abstract}=[rectangle, draw=black, rounded corners, fill=blue!40, drop shadow, text=white, font=\small] \tikzstyle{cache}=[rectangle, draw=black, rounded corners, fill=green, drop shadow, text=white, font=\small] \starttikzpicture[background rectangle/.style={draw=blue}, framed] \draw[help lines] (-5, -4) grid (5, 1); \node (Processor) [abstract, rectangle split, rectangle split parts=2] { {Processor} \nodepart{second}Cache }; \node (AuxNode01) [below=of Processor] {}; \node (Coherency) [cache, left=of AuxNode01] { {Cache Coherency} }; \node (L2-Cache) [cache, right=of AuxNode01] { {Cache} }; \stoptikzpicture } } } \stoptext

Re: [NTG-context] modules with no author

Positional graphics (MetaFun)!
by Verhaag, G.C.H.M. 03 May '11

03 May '11

Hi, Inspired by the examples given in the MetaFun manual (Oct. 2010) I tried a few, but I can't get them working! I'm specially interested in the 'Anchors and layers' (p.257, screen version!) feature. I typed in the MetaPost code as given on page 260, defined the anchors, but no circles and lines appear in the resulting pdf-file. Well I assume it must be something trivial. Anybody any idea? P.S. I use ConTeXt ver: 2011.03.30 11:21 MKIV fmt: 2011.3.30 int: english/english Regards, Gerard Verhaag

Line break in verbatim
by Aditya Mahajan 03 May '11

03 May '11

Hi, Why does verbatim text not line break properly. \setuppapersize[A5] \showframe \starttext % hyphenate is not the right word here; but illustrates the problem \type{a very very long line to see if it hyphenates or not, that can require a lot oftyping phew}. \stoptext Also, it is possible to completely prevent line breaks for \type.

I was indeed using the system's libpng, my bad. Strange though, that this comes out just now. Anyhow, thanks. Adam
