Presentation from document
by Matija Šuklje 28 Feb '10

28 Feb '10

Hullo, I was wondering the other day: since most people make "slides"/presentations basically by copy-pasting the chapter and subchapter titles into bulleted lists, would it be possible to make slides in ConTeXt by just loading a module in the original document and then when the PDF would be generated it would just take those titles and order them into a neat slide show? I know this is not how presentations should be made, but just sometimes such lazy person's slides would be a life saver.

Macro with variable number of arguments
by Otared Kavian 28 Feb '10

28 Feb '10

Hi all, I would like to write a macro which may have sometimes two, sometimes three arguments. The first and the last one are always present, but not necessarily the middle one. The unsatisfactory solution I have now is something like the example below: \define[2]\myMacroTwo{Name: #1\crlf Email: #2\crlf\thinrule\blank[small]} \define[3]\myMacroThree{Name: #1\crlf Address: #2 \crlf Email: #3\crlf\thinrule\blank[small]} \starttext \myMacroTwo{Hans}{hans(a)hagen.context.nl} \myMacroThree{Wolfgang}{Paradise of TeX, 2010}{wolfgang(a)schuster.context.de} \stoptext I think that (or rather I am certain…) in ConTeXt it is possible to define a unique macro called \myMacro which automatically tests the number of arguments: if there are only two of them the commands in \myMacroTwo are executed, while if three arguments are present, the commands in \myMacroThree are executed. Can anyone give a hint on this matter?

active chars in xml -- suggestions needed
by Philipp Gesang 28 Feb '10

28 Feb '10

Dear listmates, I need some suggestions on how to setup non breaking spaces in XML. I tried an empty element <nbsp/> to be processed as follows: \startxmlsetups xml:nbsp ~ \stopxmlsetups which was ignored by context. (I'll need something similar with \discretionary as well, I guess.) Thanks for any suggestions, Philipp -- () ascii ribbon campaign - against html e-mail /\ www.asciiribbon.org - against proprietary attachments

METAPOST -- specifying an unknown point coordinate by giving the angle from another known point
by James Fisher 27 Feb '10

27 Feb '10

This isn't specifically a ConTeXt question, but via it I've run into a seemingly simple problem in METAPOST that I just can't solve. I'm trying to draw a parallelogram by specifying: (1) the length of sides parallel to the x-axis; (2) the total height of the figure; (3) one of the interior angles. This is how I'm trying to solve it: ----------------- % Draw a parallelogram, like so: % % z3 z2 % +-----+ ^ % / / | % / / | % / / |10 units % /BL / | % +-----+ v % z0 z1 % <-----> % 5 units % % Interior angle BL = 87 degrees beginfig(1); z0 = origin; % bottom left z1 = (5,0); % bottom right y2 = y3 = 10; % shape is 10 units high x2 - x3 = x1 - x0; % top edge is the same length as bottom edge % We've completely specified z0 and z1; % We know that the top edge is the same length and angle as the bottom, but lies somewhere on y = 10; % all we have to do is specify one angle and we have a complete parallelogram. % % The following should work as it provides the following information: % the unit vector from z0 to z3 is at an angle 87 degrees anticlockwise from (0,0) -- (1,0). angle(z3-z0) = dir(87); endfig; end; -------------------- This doesn't work; using the angle() function gives the error: Not implemented: angle(unknown pair). Strictly speaking, yes, z3 has an unknown x-coordinate at that time in execution. But I am told that METAPOST is declarative, so I would expect my line of code to mean: "set the x-coordinate of z3 such that angle(z3-z0) = dir(87)". AFAICS that provides all the needed information to draw the shape. So, is there another way I can do what I want without falling into low-level trig? Best, James

PPCHTEX - questions and maybe buglet
by Bernhard Rosensteiner 26 Feb '10

26 Feb '10

Hi all, ppchtex is really nice. after experimenting with it i found some buglets: \starttext \setupchemical[axis=off,frame=on, option=test, size=medium, scale=medium, right=2000, left=3000, height=6000,textsize=medium]%textsize and option=test has no effect - why? \startchemical \chemical[SIX,SB135,DB246,SR6,Z,CRZ6][N,C,N,C,C,C,{\LC{\color[green]{NH}}}]%here color works \color[green]{\chemical[ADJ3,Five,SB235,DB4,Z345,SR3,CRZ3][N,C,H,H]}%color does not work here, manual says it should -why? \bottext{\offset[y=-\baselineskip]{Adenin}} \stopchemical \stoptext maybe someone can also explain how the OFF key works. the behaviour is strange in my opinion. i found nothing precise in the manual. on http://chneukirchen.org/blog/archive/2004/05/ppchtex.html i found following explanation: 18OFF1: do 18 small steps in direction 1 (right) but this don´t work - even with the example on the homepage. best regards Bernhard
