imposition 2UP = empty pages
by Henning Hraban Ramm 18 May '12

18 May '12

Hi there, like in January (see mail by Mari), the latest beta produces only empty pages with 2UP imposition schema; others work (tested 2SIDE and 2DOWN). e.g. \setuppapersize [A5][A4,landscape] \setuppagenumbering [alternative=doublesided,location=footer] \setuplayout [margin=0pt,width=fit] \setupbackgrounds [text][text][background=screen,backgroundscreen=0.7] \setupcolors [state=start] \setuplayout [location=middle,marking=on] \setuparranging [2UP] %[2*2*4,doublesided] \startbuffer[Fakepage] \strut \blank[force] \midaligned{2UP} \vfill \midaligned{This is page \recurselevel} \vfill \stopbuffer \setupheadertexts[\CONTEXT] \starttext \dorecurse{16}{\getbuffer[Fakepage]\page} \stoptext Greetlings, Hraban --- http://www.fiee.net/texnique/ http://wiki.contextgarden.net https://www.cacert.org (I'm an assurer)

hvdm-exm module fails
by Martin 14 May '12

14 May '12

Hi, I am trying to make use of the "hvdm-exm" module for a series of tests and that fails. Below is the basic code I am using. As I could not find a usage sample, I might have it wrong. It fails with \startexam as "undefined" and an internal message that it seems to have a language problem (WARNING ? unknown -- current language en tried). Looking into the file hvdm-exm.tex I can find the source of the error message, but it's beyond me to really understand what's going on. My ConTeXt is updated as of today (30.4.2012). I updated the core file "hvdm-exm.tex" to the 2010-11-17 version but that has no obvious influence. Also checked permissions (just to be sure, folders 755, files 644) and fixed them with no impact. Afterall, the files are all loaded. http://archive.contextgarden.net/message/20101212.154453.528d5fd7.en.html Help would be much appreciated.

FLOWcharts - connector line length?
by Mari Voipio 08 May '12

08 May '12

Hi, I've just fallen in love with the chart module, my first flowchart is almost done. I'll never draw these "by hand" again... Besides, it seems that the chart module forces me to do flowcharts "right", that should help with consistency and legibility. Now I just have to read a bit on how to do charts properly! I've figured out about text font and box sizes and making connections and all that, but there's one important question that I just can't seem to find the answer for: how do I adjust the connector line length? My labels just don't fit between the boxes and I'd have a whole A4 for a ny=5 flowchart, so I'd have space... (Oh, the other question is: is there a way to span a cell across several slots on the grid? If not, I can deal with *that*, the line is a lot more of a problem.) Thank you in advance, Mari (apparently in the "expand your ConTeXt skills" mode this week)

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...

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

Should command `\setnumber' print number in text?
by Vladimir Lomov 01 May '12

01 May '12

Hello, I faced with following behavior of `\setnumber' command, consider the example: <example file="ex1.tex"> \setupbodyfont[computer-modern-unicode,12pt] \definenumber[course] \setnumber[course]{3} \starttext Hello. \stoptext </example> Processing by context (ConTeXt ver: 2012.04.26 22:27 MKIV fmt: 2012.4.28 int: english/english) I get PDF with number 3 typeset on line above Hello. Is it expected behavior? If yes, how can I increase/set value for "number"-command (counter) then? P.S. I tried with commented `\setupbodyfont', all is ok. Is it mean that command is deprecated? --- WBR, Vladimir Lomov -- You worry too much about your job. Stop it. You are not paid enough to worry.

LuaTeX error after update to ubuntu 12.04
by S Barmeier 29 Apr '12

29 Apr '12

After updating to ubuntu 12.04, my shouts of joy were smothered by the following !LuaTeX error: cannot find OpenType font file for reading () ==> Fatal error occurred, no output PDF file produced! mtx-context | fatal error: return code: 70 I ran mtxrun --script fonts --reload, updated to the latest context version, ran luatools --generate and context --make and still am presented with the above error message after 10-15 minutes of paralysing processing. The compiling seems to run as always, until it reaches the last page, at which point the computer freezes and takes about 10 minutes to present me with the error. The following is another snapshot of the output which I noticed for the first time: system > logs > lua: compiling /home/user/texmf-cache/luatex-cache/context/2448223e6631addb83df348d74153606/fonts/otf/andika-r.tma into /home/user/texmf-cache/luatex-cache/context/2448223e6631addb83df348d74153606/fonts/otf/andika-r.tmc fonts > otf loading > preprocessing and caching took 73.009 seconds Any ideas where to start? Many thanks, Severin

Uncovering Slides in a Presentation with Progress Meter
by Troy Henderson 29 Apr '12

29 Apr '12

I am trying to uncover content within an itemized list, and I am using \phantom to get the desired effect. However, I would like to tweak the progress meter to consider these "pages" as the same instead of separate. I am pasting a minimal example below, and I would like to know if (1) there is a more "standard" way (instead of using \phantom) of uncovering the second item in the itemized list (2) the progress meter can be modified to illustrate 3 (instead of 4) total pages AND not have the progress meter change between pages 2 and 3 (since I want to view them as the same "page") Troy Henderson -- \setuppapersize[S6][S6] \setuppagenumbering[state=stop] \setupinteraction[page=yes,menu=on,state=start] \setupsubpagenumber[state=start] \setuplayout[bottom=12pt] \startinteractionmenu[bottom] \interactionbar[alternative=f] \stopinteractionmenu \starttext First page \page \startitemize \item Foo \phantom{ \item Bar } \stopitemize \page \startitemize \item Foo \item Bar \stopitemize \page Last page \stoptext

Units module and unbowed letters ..
by Jaroslav Hajtmar 29 Apr '12

29 Apr '12

Hello ConTeXist. When I work with Units module, I gain at the output of the greek "mi" letter an italic font. It seems strange. It is so in terms of typography correctly or not? Can also be used for typing (with units module) unbowed letters? Thanx Jaroslav Hajtmar Here is my example: \usemodule[units] \usetypescript[times][texnansi] \setupbodyfont[times,12pt] \starttext 5\,\Micro\Meter 5\,\uMeter 5\,μm \stoptext
