question about MPpositiongraphic
by Thomas A. Schmitz 04 Jan '09

04 Jan '09

Hi all, first, best wishes for the New Year to all of you - may 2009 bring peace and fortune and world domination for ConTeXt! And my little question - trivial for the resident experts, I guess, but I can't find a solution: I want to write a little macro that will allow me to place a thin curved line under letters (metrical symbol for synizesis). Now that metafun is so fast in mkiv, I thought I'd use a MPpositiongraphic for that purpose, but my problem is that I can't make the graphic really local - when it is used more than once in a document, Metafin uses the last values for all occurrences. I tried grouping and the "save" command, but to no avail. Here's an example that shows the problem: \startMPpositiongraphic{placesynizesis} StartPage ; begingroup ; save a ; initialize_box(\MPpos{\MPvar{self}}) ; numeric a ; a = ExHeight/6 ; z1 = llxy ; z2 = lrxy ; z3 = 1/2[z1,z2] ; z4 = ((x1 + 2a),(y1 - 2a)) ; z5 = (x3, (y3 - 4a)) ; z6 = ((x2 - 2a),(y2 - 2a)) ; path syn ; syn := z4 .. z5 .. z6 ; pickup pencircle scaled a ; draw syn ; anchor_box(\MPanchor{\MPvar{self}}) ; endgroup ; StopPage ; \stopMPpositiongraphic% \setMPpositiongraphic{POS}{placesynizesis} \define[1]\synizesis {\hpos{POS}{#1}} \starttext \switchtobodyfont[25pt] test: \synizesis{au} and \synizesis{aeiou} \stoptext Any solution to this conundrum? All best Thomas

New luatex mailing list announcement
by Taco Hoekwater 04 Jan '09

04 Jan '09

Hello everybody, The dev-luatex(a)ntg.nl list has seem more and more messages per day over the past months. We are of course very pleased with the growing interest in Luatex, and we believe the time has come to create a general usage mailing list. Karl Berry at TUG has set up a brand new mailing list for us that can be subscribed to via this URL: http://lists.tug.org/luatex or by sending an email message to luatex-subscribe(a)tug.org Of course questions about building and patching the Luatex engine should stay on dev-luatex, and questions regarding ConTeXt mkiv should stay on ntg-context. But the new list will be the best location for all general Luatex discussion and usage questions. A request for the people currently on the dev-luatex list: if you have an interest in Luatex but are not planning on becoming an active developer, please switch to the new list. Doing so will make life a bit easier for the active developers and packagers, not all of which are necessarily luatex users and interested in discussions. Have fun, Taco Hoekwater For the Luatex team

Hi all, I have the question how to put a (pure) colon into a figure or table caption. \let\floatcaptionsuffix=: \placefigure[fig:cow]{cow}{\externalfigure[cow]} produces: Figure 1.: cow What I want is: Figure 1: cow i.e. the colon without the additionally dot. Does somebody know a solution for this simple problem? With many thanks for any hint, Albrecht

Problem Passing \starttabulate into Lua
by Tad Ashlock 01 Jan '09

01 Jan '09

I'm trying to create a ConTeXt macro (mkiv) that will manipulate the macro argument's text with Lua and then feed it back into ConTeXt with tex.print(). My approach worked correctly until I called the macro with \starttabulate ... \stoptabulate in the macro's argument. So I started reducing the problem down to a minimum example which surprisingly turned out to have nothing to do with the manipulations I was performing. Here is the working example (without \starttabulate): \long\def\testmacro#1{\directlua0{d='\luaescapestring{#1}'}} \starttext Hello, world! \testmacro{% testing} \stoptext Here is the broken example: \long\def\testmacro#1{\directlua0{d='\luaescapestring{#1}'}} \starttext Hello, world! \testmacro{% testing \starttabulate \NC 0 \NC testing tabulate. \NC \NR \stoptabulate} \stoptext Here's the output: ===================================== MtxRun | loading configuration for C:/context/tex/texmf/web2c from C:/context/tex/texmf-cache/luatex-cache/context/2fea56f92e5267d7cc9662e4d5f52e1e/trees/53ad5f8b88994bdd02baa17501789699 MtxRun | run 1: luatex --fmt="C:/context/tex/texmf-cache/luatex-cache/context/2fea56f92e5267d7cc9662e4d5f52e1e/formats/cont-en" --lua="C:/context/tex/texmf-cache/luatex-cache/context/2fea56f92e5267d7cc9662e4d5f52e1e/formats/cont-en.lua" "./test.tex" (test.tex ConTeXt ver: 2008.10.31 13:58 MKIV fmt: 2008.12.24 int: english/english language : language en is active system : cont-new loaded (C:/context/tex/texmf-context/tex/context/base/cont-new.tex systems : beware: some patches loaded from cont-new.tex (C:/context/tex/texmf-context/tex/context/base/cont-new.mkiv) (C:/context/tex/texmf-context/tex/context/base/cont-mtx.tex)) system : cont-fil loaded (C:/context/tex/texmf-context/tex/context/base/cont-fil.tex loading : Context File Synonyms ) system : cont-sys.rme loaded (C:/context/tex/texmf-context/tex/context/user/cont-sys.rme (C:/context/tex/texmf-context/tex/context/base/type-tmf.tex) (C:/context/tex/texmf-context/tex/context/base/type-siz.tex) (C:/context/tex/texmf-context/tex/context/base/type-otf.tex)) bodyfont : 12pt rm is loaded specials : pdftex loaded system : test.top loaded (test.top) (test.tuo) (test.tuo) systems : begin file test at line 2 !

I tried \def with and without \long. I tried other \start* ... \stop* commands (different errors, but still broken). Plus many more variations. At this point I'm convinced that there's something fundamental that I'm not understanding. What is the general method for taking any chunk of ConTeXt code and passing it into Lua so that it can be written back out with tex.print()? Info: running on Windows XP, SP3 -- ConTeXt: 2008.10.31 -- LuaTeX, Version snapshot-0.31.2-2008121200, build 1659 (The older versions of ConTeXt and LuaTeX are necessary because of the problem the latest Windows versions are having. See the "Serious Bug?" thread.) Thank you, Tad Ashlock

embedding 3d pdf
by Michail Vidiassov 01 Jan '09

01 Jan '09

Dear All, since ConTeXt lacks support for embedding 3D models (U3D or PRC) into PDF (btw, is pdf annotations support in context/luatex combination fit for end-user or is "in transition"?) I have tried to embed some 3D PDFs from http://asymptote.sourceforge.net/gallery/3D%20graphs/ and http://www.iaas.msu.ru/tmp/u3d/pdf/ using \externalfigure[3dpf.pdf] \startpagefigure[3dpdf.pdf]\stoppagefigure \copypages[3dpdf.pdf][n=1] but only the preview (flat) images show up, not the 3D model, that must appear after clicking on it in Adobe Reader. File size shows that the 3D annotation data was not taken from the 3D PDF file into ConTeXt output. Any advice on possible workarounds? Any hope for ConTeXt fixes? Or making a link to an external PDF file is the only option for now? Sincerely, Michail PS. I have seen the code from Renaud AUBIN in the "U3D (embedded 3D objects)" thread, http://www.ntg.nl/pipermail/ntg-context/2006/020220.html but it is too ugly and old a hack to start any work from.

PDF bookmarks appear twice
by Andrey Riabushenko 31 Dec '08

31 Dec '08

I have found similar issue was discussed in this list, but it doesn't contain a suitable solution for me These command work just fine to add bookmark for every part, chapter and etc. \setupinteraction [state=start] \setupinteractionscreen [option=bookmark] \placebookmarks [part,chapter,section,subsection] [chapter] But I want to add three additional bookmarks (without adding them to the contents): title page, resume(second page), contents. I have defined it the following way: \definemakeup[Titlepage][pagestate=start, page=right] \definemakeup[Resume][pagestate=start, page=right] \definestartstop[Abstract][before={\page[blank,right] \midaligned{\bf Abstract}\startnarrower[2*middle]}, after={\stopnarrower\blank[big] }] \starttext \startTitlepagemakeup \bookmark[chapter]{Title page} \tfd Title page \\ \stopTitlepagemakeup \startResumemakeup \bookmark[chapter]{Resume} \startAbstract Abstract paragraph full of text \stopAbstract Author name \stopResumemakeup \title{Contents} \bookmark[chapter]{Contents} \placecontent[interaction=all] \stoptext In this case bookmarks appear twice in the bookmark menu. If I use \bookmark{} without [chapter] the bookmarks do not appear at all. I have tried to put bookmarks out of start/stop environments but it didn't help. How to work around this issue?

Looks like a bug in \typefile[option=LANG]
by Andrey Riabushenko 31 Dec '08

31 Dec '08

I have defined a new float environment for source file listings. \definefloat [listing] [listings] \definetyping[listing][numbering=file] \placelisting[lst:set]{Example of set tree} { \typefile[listing][option=C]{set.cpp} } It works just as expected. Then I have tried to change standard color palet with my own palet. \definepalet[corp-pretty][prettyone=corp-color-darkblue, prettytwo=corp-color-blue, prettythree=corp-color-lightblue, prettytwoone=corp-color-grey, prettyfour=corp-color-green, prettyfourone=corp-color-green, prettyfourtwo=corp-color-green, prettyfourthree=corp-color-green, prettyfourfour=corp-color-orange, prettysixone=corp-color-orange, prettysixtwo=corp-color-orange prettyeight=corp-color-orange, prettynine=corp-color-orange] \definefloat [listing] [listings] \definetyping[listing][numbering=file, palet=corp-pretty] \placelisting[lst:set]{Example of set tree} { \typefile[listing][option=C]{set.cpp} } The colors did not appear, in the texexec output I got lots of errors like color : TEXcorp-pretty:prettythree is not defined color : TEXcorp-pretty:prettythree is not defined color : TEXcorp-pretty:prettyone is not defined color : TEXcorp-pretty:prettytwo is not defined color : TEXcorp-pretty:prettythree is not defined color : TEXcorp-pretty:prettyfour is not defined NOTICE \typefile LOOKS FOR PALET "TEXcorp-pretty" and not "corp-pretty" as I have defined. There is some bug or "feature" that makes an implicit assumption of the palet prefix name - TEX. I have managed to make it work by definition a palet with name TEXcorp-pretty and still passing as palet option of \definetyping the name corp-pretty, but it is a ugly hack.

create and grade multiple choice exams with MUCH an ConTeXT
by batela 31 Dec '08

31 Dec '08

Dear Sirs, For create and grade my MCQ (multiple choice quiz) I use the MUCH command that in had found at http://fourier.math.uoc.gr/~mk/much/. this is a very useful command for create and grade quizzes. Actually my main propose is use MUCH with context (or luatext). I prepare my exams in this way: Each question = one file Question example: """"" Today is: . 31 December --- the true question is the first . 25 December . 13 Mars . """"""""""""""""" In the test-description I include my specifications. And them I do: much create test-description A mc-outfile.tex is created. Now I do: pdflatex exam.tex for making the pdf file with all exams. If you can help I would use ConTeXT to prepare the pdf file. The migration should be very easy. I think there is necessary to define in context several commands like: \newcommand{\mcglobalheader} \newcommand{\mcpaperheader} \newcommand{\mcpaperfooter} \newcommand{\mcquestionheader}{\noindent{\bf Question \mcquestionnumber}: } \newcommand{\mcquestionfooter}{} In the file questions (mc-output.tex). """""""" mc-output.tex """""""""""" \mcglobalheader \def\mcserialnumber{500} \mcpaperheader \def\mcquestionnumber{1} \mcquestionheader How many circular orderings of the numbers $0,1,\ldots,10$ are there? (Two circular orderings which differ only by a rotation are not considered different.) \\ {$A$}: $10!$ \ \ {$B$}: $3^{11}$ \ \ {$C$}: $11!$ \ \ {$D$}: $9!$ \ \ \mcquestionfooter \mcpaperfooter %%%%% another exam \def\mcserialnumber{501} \mcpaperheader \def\mcquestionnumber{1} \mcquestionheader In how many ways can we select, from a set of 20 people, a committee of 3 different persons with a chair, secretary and member? \\ {$A$}: $20\cdot19\cdot18$ \ \ {$B$}: $\frac{20!}{3!}$ \ \ {$C$}: $20^3$ \ \ {$D$}: $3^{20}$ \ \ \mcquestionfooter \mcpaperfooter %%%%%%%%%%% Thanks a lot for your support. Happy New Year to all Jorge
