multitone color problem
by Peter Rolf 07 May '12

07 May '12

Hi, just playing around with spot colors and run into this problem. tested with 23.04.2012 and ??.11.2011, same result. the color definition leads to an invalid pdf. % multitone.tex---- \nopdfcompression \setuppagenumber[state=stop] \definemultitonecolor[combicolor] [blue=.12,yellow=.28] [c=.1,m=.1,y=.3,k=.1] \starttext \null \stoptext %------------------ I also attached the original example (spot.tex). Best wishes, Peter

Complexeslide module
by Romain Diss 07 May '12

07 May '12

Hi all, In some of the lasts Aditya's posts, one can understand that some work is already done on a new module: complexeslide. Is there any information about this new module: goal (beamer like?), actual state, roadmap... Thanks. -- Romain Diss <romain.diss(a)yahoo.fr>

References to floats.
by Robert Blackstone 07 May '12

07 May '12

Dear list, Presently I am working on a book that contains many musical examples, some of them rather large (even page-filling). It is difficult to predict where they will finally be placed, at least when I do not want to spoil the layout too much by forcing every example to be placed at the point where it occurs in the .tex-file. So when dicussing an example I always refer to it with \in{ex.}{ref} and \at{page}[ref]. Sometimes however the example is placed at the same page as the text discussing it. Is there any trick to adapt the reference to this situation, so that, instead of saying, for instance, "ex. 3.4 on page 12", it just says "ex. 3.4", or "ex. 3.4 below" or even "ex. 3.4 on this page"? (One imagines that in the last stage of typesetting the file ConTeXt "knows" that the reference and the referenced float will be on the same page, but I have no clue how I could use this knowledge.) Thanks in advance for any help. Robert Blackstone

Before I re-invent the wheel and write my own, has anybody written Mk IV-compatible typescripts for the Venturis ADF/VenturisSans ADF typefaces they wish to make available? -- Bill Meahan K8QN Cat: n; A purr-bearing mammal

missing pagebreak using vim-module for typing
by Xenia 07 May '12

07 May '12

Dear context folks, since Aditya recommended I am using the vim module for including MATLAB-files in my TeX-files. But for longer code snippets there is no pagebreak, so that the code is cuttet at the end of the page. What do I have to do? current version: 2012.04.19 23:18 Thanks, Xenia

Metapost/Metafun Q: using variables and "building blocks"?
by Mari Voipio 06 May '12

06 May '12

Hello all, any graphic experts around who can bump me past a stupid hinder on my way to understanding MPgraphics? I'm trying to create a system of describing certain type of braiding patterns (fingerloop braiding), based on what has been used in the field before me - but they did it all manually either by pen or computer, and I just do not fancy doing 40+ patterns by hand in Inkscape, especially as my pattern recipe book keeps expanding and I'm planning on that, too. I think Metapost could be the solution, because I need simple shapes and sometimes complicated but well-regulated paths/arrows to go between them; I'm just being a clueless newbie, too much in the WYSIWYG vector graphics mode to really know what to do. Mostly with the examples in the Metafun manual I've managed to get as far as to my basic building block, two circles joined by a curve: \startMPpage path p, q, r ; p := fullcircle scaled 8mm ; q := p shifted (0cm,24mm) ; r := center p .. (12mm,12mm) .. center q ; pair pr, qr ; pr := p intersectionpoint r ; qr := q intersectionpoint r ; r := r cutbefore pr cutafter qr ; r := r cutends 0.2mm ; draw r withpen pencircle scaled 0.2mm withcolor black ; draw p withpen pencircle scaled 0.2mm withcolor black ; fill p withcolor white; draw q withpen pencircle scaled 0.2mm withcolor black ; fill q withcolor black; \stopMPpage However, I don't seem to be able to find the answers to the next questions: a) I need to be able to stack four of these on top of each other and then four mirrored ones next to them (all-in-all a 2 x 4 grid/block), and probably a 1-block space between the two columns. I realize I can do that with "shift", but should I make my single 'building block' a group, a buffer or overlay or something else? Keeping in mind that I will have to be able to draw a path/arrow on top, so I need to know where they are. (At some point I need to expand to more columns, but the number of rows is still 4 as we have humans have just four aligned fingers per hand - thumbs aren't counted - but one can add hands i.e. people to work wider braids.) b) The circles p and q can be filled with the same colour or two different colours, and each of the blocks in a pattern can have different fill colour (e.g. two totally black, two totally white, two half-and-half with either black or white on top). The pen/outline colour should stay as black, which means that I can't implement the symbol example in the Metafun manual (the smiley that is totally switched from black to red). I don't mind having different blocks for monocoloured and bicoloured versions, but it would be nice to be able to say something like \usesloop[lh,blue] for 'take a single-coloured left-hand loop in blue' instead of having to dig deeper into the MP code every time. I assume the answer is "use variables", but how? I used millimeters here because it just feels more natural to me, that's what textile crafts does (when not based on inches like quilting and scrapbooking...). The measurements won't be shown anywhere - these are graphs or pictograms, not real pictures - so I can still switch to using something else. Besides, if the "building block" approach works, there isn't that much to be changed, get the first block right and the rest can be calculated from there. Any ideas on how I can achieve the ease that surely exists somewhere there? I'll take plain Metapost or a combination of Metapost and Metafun + ConTeXt as I'll use ConTeXt anyway to achieve multi-format output with a minimum of fuss. Help thankfully received, as always, Mari PS. Today's craft related metaphor: I feel just like I was staring at a messed up skein of yarn: I know that I'm now holding one of the ends, I thus can start to untangle the knot - and the more I pry loose, the less there's left to sort out. However, in the beginning the process tends to be very slow and awkward...

bug with \setupnotation[number=no] and sectioning commands
by Pablo Rodríguez 06 May '12

06 May '12

Hi there, I'm afraid that note numbering in body text is wrong in latest beta (the bug was also in previous beta). Here you have a sample that shows the bug: \setupnotation[footnote][number=no] \setuphead[chapter][number=no] \starttext \chapter{First chapter} one\footnote{two} \section{First section} three\footnote{four} \stoptext There should be no note numbering, but the body text takes the sectioning command number for the footnote references (which is obviously wrong). Many thanks for your help, Pablo -- http://www.ousia.tk

Cross-document referencing not working!
by Verhaag, G.C.H.M. 05 May '12

05 May '12

Hi ConTeXt User's, I'm struggling with cross-document referencing, but can't get it working! When I for example use \useexternaldocument[tst][test][A test external] together with \from[tst] the test.pdf file is correctly opened in Acrobat Reader. But the \in{section}[tst::crossref] doesn't open the test.pdf file at all?! The jump to the 'crossref' section doesn't seem to work! Please take a look at the two included test files. I first compile test.tex followed by the compilation of crossref.tex. Currently I use: ConTeXt ver: 2012.01.25 14:16 MKIV fmt: 2012.2.7 int: english/english. Regards, Gerard Verhaag
