That's the answer I sought. The mechanism is called \attachment and it is in a working state - fine! Any pointers to usage examples? BTW it is not just matter of taste. Many tools produce not just models for 3D PDF (U3D or PRC), but complete PDF documents with additional JavaScript-programmed actions linked to proprietary toolbars etc. If this extended surrounding of the model is to bee preserved attachfile instead of embedfile approach is a must.

Ampersand in Metapost
by Marco 14 May '10

14 May '10

Hi, I have a problem producing an ampersand in metapost. In ConTeXt it works as expected. Have a look at the following example. \starttext \& % OK \startMPcode label(textext("\&"),origin); % produces error \stopMPcode \stoptext The compile time error message is as follows: ! Misplaced alignment tab character &. l.1 \MPLIBsettext{1}{& Marco

Problem with the loading cid fonts in luatex-plain format
by Li Yanrui (李延瑞) 14 May '10

14 May '10

Hi, The following is my test file for Adobe OTF fonts loading. \font\cidfont=file:AdobeSongStd-Light \cidfont 测试 \bye I have put the Adobe-GB1-4.cidmap file into the directory which contains the test file. As a result, luatex gives this waring: LuaTeX warning: lua-loaded font [51] (file:AdobeSongStd-Light) has no characters! I remember it could work before. My environment: linux x86 / context minimals 2010.05.08 13:33 / luatex 0.60.1-2010050821 -- Best regards, Li Yanrui (李延瑞)

Context 2010.05.08
by Taco Hoekwater 14 May '10

14 May '10

As Hans wrote already, there is a new context current. The short news summary: * Many of the stubs for the ruby tools have gone away. If you want one of the old command names back, just create a link from mtxrun to the required name, e.g. copy mtxrun.exe to mptopdf.exe on windows. Eventually all perl and ruby scripts will be gone. Most functionality is already provided by lua variants. * The hyphenation patterns for German, German (old), Hungarian and Spanish have been updated from the tex-hyphen project. * New versions of the ancientgreek, letter, and simplefont modules are included. * New modules (mkiv only): barcodes and punk * Support for shockwave flash has been updated (mkiv only). The backend code has been rewritten and currently only pdf is supported. * The split between mkii and mkiv is getting more complete. Only a few mkii bug fixes have taken place. * Typescripts are now split completely and no definitions are shared; loading of a mkio/mkiv file takes precedence over a tex file. As always, there is a detailed changes file on the wiki: http://wiki.contextgarden.net/Context_2010.05.08 This current context is meant for texlive 2010, but there is a little time before the final freeze of the texlive repository, so there will be a bugfix update in a week or so. If you have pending urgent bugs (especially in mkii) this would be an excellent time to report them. You could try the mailing list, but a better approach to bug reporting is to simultaneously create a tracker item at this url: http://tracker.luatex.org/search.php?project_id=2 Best wishes, Taco

10+ reasons why I still use MKII
by Mojca Miklavec 14 May '10

14 May '10

Dear Hans, since you have promissed another hotfix release for TL 2010, here's a list of issues that I had with my thesis and MKIV (some have already been fixed in the due time, but many remained). I probably wouldn't have had those "problems" if I was designing my document in MKIV from scratch, but just recompiling in MKIV didn't work out for several reasons listed below. 1.) Minimal example: \usetypescript[iwona] \setupbodyfont[iwona] \starttext $a+b$ \stoptext Output: !define font : font with name Iwona-Math-Letters-Regular is not found !define font : unknown font Iwona-Math-Letters-Regular, loading aborted !define font : unable to define Iwona-Math-Letters-Regular as \*iwona6ptmmmr33* !define font : font with name Iwona-Math-Letters-Regular is not found !define font : unknown font Iwona-Math-Letters-Regular, loading aborted !define font : unable to define Iwona-Math-Letters-Regular as \*iwona8ptmmmr22* !define font : font with name Iwona-Math-Letters-Regular is not found !define font : unknown font Iwona-Math-Letters-Regular, loading aborted !define font : unable to define Iwona-Math-Letters-Regular as \*iwona11ptmmmr11* !define font : font with name Iwona-Math-Letters-Regular is not found etc. I need to figure out why, though it works (I don't see deficiencies in output yet). 2.) Recently discussed on the mailing list - stopper has no influence in MKIV: \setupcaptions[stopper={:}] \starttext \placefigure{title}{\framed{bla}} \stoptext 3.) Bibliography citations give different result with the same setup (different numbers and different spacing in \placepublication - might be also worth testing with grid typesetting as I wasn't able to set up the alignment properly in MKII last time when I have tried). I'm not sure which one is right, but there's probably no reason to produce different results. \usemodule [bib] \setuppublications [alternative=num, criterium=all, sorttype=cite] \starttext \startpublication[k=a,t=article]\arttitle{a}\stoppublication \startpublication[k=b,t=article]\arttitle{b}\stoppublication \startpublication[k=c,t=article]\arttitle{c}\stoppublication x\cite[a,b,c] \placepublications \stoptext 4.) The following problem must have appeared recently (it was working ok in September): in MKII the encoding is completely screwed up: \usemodule[gnuplot] \enableregime[utf-8] \starttext \startGNUPLOTscript[integrated risetime] plot sin(x) t 'šin(čix)' \stopGNUPLOTscript \useGNUPLOTgraphic[integrated risetime][1] \stoptext A slightly more basic example: \enableregime[utf-8] \starttext \startbuffer[gnu] \startMPcode draw \sometxt{čšž}; \stopMPcode \stopbuffer čšž \getbuffer[gnu] \stoptext 5.) Weird formula number placement when long equations are used in MKIV \def\oklepaj#1{\left(#1\right)} \starttext \placeformula \startformula {\dot N}(t)= A\oklepaj{\exp\oklepaj{-\frac{t-t_0}{τ_{\text{eksp.}}}}-\exp\oklepaj{-\frac{t-t_0}{τ_{\text{fast}}}}}+ B\oklepaj{\exp\oklepaj{-\frac{t-t_0}{τ_{\text{eksp.}}}}-\exp\oklepaj{-\frac{t-t_0}{τ_{\text{slow}}}}} \stopformula \stoptext 6.) I know that \NR is not the most appropriate way to go into next row, but the following gives considerably different results in MKII and MKIV: \starttable[|l|] \NC \type{a} \NC\NR \NC \type{a} \NC\NR \NC \type{a} \NC\NR \stoptable 7.) I know that there's a longstanding left vs. right bug, but flushleft is no solution in the following case (compare MKII and MKIV again): \definedescription [latexdesc] [headstyle={\ss\bf},style=normal,align=left,location=hanging,width=fit,margin=0cm] \latexdesc{step E (expectation):} \input tufte \latexdesc{step M (maximization):} \input tufte 8.) \definetypeface [boldmath] [mm] [boldmath] [latin-modern] [default] \starttext $\boldsymbol{\theta}$ \stoptext 9.) Note the big difference of when the formula starts vertically on page: \starttext \startformula a+b \stopformula \stoptext 10.) Different square root shape/variant used: $\frac{1}{\sqrt{2πσ_i^2}}$ Original formula: \startformula \startcases \NC ρ_0, \NC for $i=0$, \NR \NC ρ_i\,\frac{1}{\sqrt{2πσ_i^2}}\exp\biggl(-\frac{\left(x_j-μ_i\right)^2}{2σ_i^2}\biggr), \NC for $i\in\left\{1,2\right\}$. \NR \stopcases \stopformula but I cannot reproduce the big difference it makes in original document on a smaller scale. 11.) Missing bibliography entries: \usemodule[bib] % this line spoils the show \setuppublications[alternative=num] \setuppublicationlayout[webpage]{% \inserttitle{\bgroup\it }{\egroup. }{}% \inserturl{}{}{}% } \startpublication [k=FAIR,t=webpage,u=http://www.gsi.de/fair/] \biburl{http://www.gsi.de/fair/} \title{FAIR -- Facility for Antiproton and Ion Research} \stoppublication \starttext \cite[FAIR]\par \placepublications \stoptext 12.) \nocite[nonexistent] generates an empty [n] in bibliography in MKII, while it has zero effect in MKIV (it should at least generate an error). 13.) Different spacing \setupwhitespace[big] \def\dictentry#1#2{\hbox{\bf#1}\hbox{\hbox to 1em{}\hbox{#2}}\blank[4mm]} \starttext \dictentry{clipping}{preboj} \dictentry{clustering}{gručenje} \stoptext 14.) Two very weird issues with section alignments, but I'll continue later - I need some fresh air now. ------ What's the following BEWARE useful for? systems : BEWARE: syntex functionality is enabled!

How to achieve transparency?
by Marco 14 May '10

14 May '10

Hi, I wonder how transparency works in ConTeXt. I expect in the following example the text to be transparent. That's not the case. \definecolor [myI] [r=1, g=.9, b=.7, a=.8] \definecolor [myII] [r=0, g=.9, b=0, a=.8] \setupbodyfont [sans, 36pt] \def\t{Test} \starttext \bf \hbox{\color [myI] {\hbox to 0pt{\t}} \color [myII] {\t}} \stoptext Thanks in advance Marco

does expandaparameters work
by Erik Margraf 14 May '10

14 May '10

Hello, I use "\expandparameters" in a macro definition. -- \expandparameters\setupbackgrounds[page][background={\currentvalue,#1}] -- This works in MkII (texexec), but doesn't work in MkIV (context). If I define all layers in a single declaration, the results with MkII and MkIV are identical. Should this work? Or do I have to add something for MkIV? Thanks and kind regards Erik

Two questions about a mysterious behavior of ConTeXt
by Marius 14 May '10

14 May '10

Hello, I encountered two mysterious behaviours of ConTeXt mkvi and can't resolve them by my self. So. The first one is: why does ConTeXt behaves differently then I use environment ant then I don't. There are two versions of the same code in the attached files. The test.tex uses environment test-env and test2.tex does not. Then why test.tex compiles while test2.tex does not? The second question is: why in the test-env.tex file ver2 of code compiles while ver1 does not? Thank you, Marius
