issue with imposition
by Pablo Rodríguez 19 Jan '09

19 Jan '09

Hi there, I would like to use the imposition capabilities from ConTeXt to be able to print a PDF book in a standard laser printer. To save paper, I use the 2UP arranging option thanks to this code from the wiki: \definepapersize [filius][width=135.9mm, height=231.8mm] \setuppapersize [filius][A4,landscape] \setuparranging [2UP,doublesided] \setuplayout [backspace=0pt, topspace=0pt, width=middle, height=middle, location=middle, header=0pt, footer=0pt, grid=no, marking=off] \starttext \filterpages[ZittrainTheFutureoftheInternet.pdf][4:351][height=21cm] \stoptext The PDF file can be downloaded from http://futureoftheinternet.org/static/ZittrainTheFutureoftheInternet.pdf. The issue here is that I get a resulting paper size with the filius height and not with 21cm from A4. I have tried have the output in a standard A4 paper size, but all that I got is a scaled down PDF. I would like to avoid scaling the document if that were possible. Is there any way, given the example above, to impose the filius paper size on a real landscape A4 without having to scale down the PDF document? Thanks for your help, Pablo

Math align with \startcases
by Otared Kavian 19 Jan '09

19 Jan '09

Hi everyone, This question is primarily intended for Aditya… but I guess other fellows on the list can also help me solve the following alignment problem: Is it possible to have an alignment like the rsult of the following with \startcases...\stopcases? \starttext \startformula \startmatrix[align={right,left,right},distance=3pt,left={\left\{}, right={\right.}] \NC -\Delta u + g(u) \NC{} = f \NC \quad\mbox{in } \Omega\NR \NC \displaystyle {\partial u \over \partial {\bf n} } \NC{} = h(u) \NC \quad\mbox{on } \partial\Omega \NR \stopmatrix \stopformula \stoptext Actually I used to have such alignments with the following structure (in good old plain TeX...): \starttext \startformula \cases{ \eqalign{ -\Delta u + g(u) &= f \cr \displaystyle {\partial u \over \partial {\bf n} } &= h(u) \cr } \quad \eqalign{ &\hbox{in } \Omega \cr &\vphantom{{\partial u \over \partial {\bf n} }} \hbox{on } \partial \Omega \cr } } \stopformula \stoptext (which gives approximately the same result as the first example above, but clearly the math-alignment structure set up by Aditya and Hans is much more elegant. (Although I prefer the vertical distance between the lines obtained with my plain TeX structure: by the way is it possible to fine tune such things in ConTeXt). So my question is: whether one can use \startcases ...\stopcases instead of \startmatrix ... \stopmatrix in order to obtain the result of the plain TeX example? Thanks in advance: OK

A few questions about aligned maths
by Morgan Brassel 19 Jan '09

19 Jan '09

Hi everyone, I read carefully the two 'My Way' from Aditya regarding math alignment (thank you for those, they were extremely useful to me, and should maybe get even more visibility on the wiki), and I have some questions about it: 1) Is there a way to modify interline spacing in 'cases' environment? I find it a bit short when using the displaystyle option. 2) I noticed that the interline spacing is not the same in the 'align' and 'aligned' environment (it's larger in 'align'). Is there a way to make 'aligned' use the spacing of align? It looks better with displaystyle maths. 3) Aditya, I saw your remark in your 'My Way' concerning the 'multline' environment. I must admit I would really be glad to see it appear in ConTeXt! I'm afraid I'm not able to implement it myself... I use it a lot with amsmath: when a formula is just too long for one line, I put it on two with multline. The first part of the formula is left aligned on the first line, and the second part is right aligned on the second line. It seems impossible to get the same result with only 'align'. Would it be difficult to make it available in ConTeXt? Best regards, Morgan

If I run this minimal version of mtx-update.lua, I get the same error. > If I call the rsync ... command directly, it completes... What does locate libiconv.2.dylib return you? Do you have any other version apart from the one in /usr/lib? otool -L /usr/lib/libiconv.2.dylib probably gives you 7.0.0, right? My only explanation is that luatex shields some system libraries. I have this for example ... > otool -L /Developer/SDKs/MacOSX10.3.9.sdk/usr/lib/libiconv.2.dylib /Developer/SDKs/MacOSX10.3.9.sdk/usr/lib/libiconv.2.dylib: /usr/lib/libiconv.2.dylib (compatibility version 5.0.0, current version 5.0.0) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 71.0.0) Maybe, maybe, maybe ... the cross-compiled luatex binary includes /Developer/SDKs/MacOSX10[whatever]/usr/lib/ into library search path with bigger precedence and then luatex sees that library before the one in /usr/lib when rsync requests it? Taco - would that be possible? How could one check if that might be the case? Mojca

Hi, within the next 24 hours contextgarden.net will be on a new machine. Expect some broken things. If things keep being broken after one day from now, I'd be happy to receive bug reports. Warning: this also affects the update of the distribution (formally known as the "minimals"). I'll put a page on the wiki where I list the status of the transition: http://wiki.contextgarden.net/New_Server (not there yet) Thanks for your patience!

weird bug updating minimals
by Thomas A. Schmitz 18 Jan '09

18 Jan '09

Hi all, Mojca, after Taco resolved one issue with the latest luatex, I was trying to update on my osx-ppc box, and I am encountering a strange bug: when I run the ./first-setup.sh script, the rsync processes fail with this message: MtxRun | using script: ./bin/mtx-update.lua dyld: Library not loaded: /usr/lib/libiconv.2.dylib Referenced from: /bin/sh Reason: Incompatible library version: sh requires version 7.0.0 or later, but libiconv.2.dylib provides version 5.0.0 and so on. Now this box has several more or less abandoned installations of darwinports and fink, but this looks like it's trying to link to the library provided by the system (OS X 10.5.6) and complaining it's too old. Any pointers to this one? All best Thomas

Hallo! \setupcolors[state=start] \starttext \starttable[ o1 | \{C{red} |] \VL red \VL\SR \stoptable \stoptext This was an older example which worked some years ago (see: http://www.ntg.nl/pipermail/ntg-context/2006/020803.html) but is not working anymore. What is the problem here? Wolfgang

MPgraphic with rounded corners
by Duncan Hothersall 18 Jan '09

18 Jan '09

Hello all. I have adapted a bit of MP code from Aditya from a mailing list message dated 2006-05-19 (http://archive.contextgarden.net/message/20060519.214124.9174ac0e.en.html) to ensure that when a page break occurs in a textbackground there is a forced vertical space inside the box at the top of the new page. This code works fine for me (although interestingly not in the garden): \setupcolors[state=start] \startuseMPgraphic{mpos:par:myexample} path p; for i = 1 upto nofmultipars : p := multipars[1] topenlarged 8pt bottomenlarged 8pt; fill p withcolor 0.9white ; draw p withcolor black withpen pencircle scaled \MPvar{linewidth}; endfor; \stopuseMPgraphic \definetextbackground[ExampleBackground] [mp=mpos:par:myexample,location=paragraph,leftoffset=1em,rightoffset=1em,rulethickness=1pt] \starttext \input knuth \endgraf \starttextbackground[ExampleBackground] \dorecurse{13}{\input knuth \endgraf} \stoptextbackground \input knuth \endgraf \stoptext But now I need to make this box have rounded corners, and I am very confused when reading core-pgr.tex because that is a level of MP code I just don't understand. Would somebody please be able to tell me what to change in the above to make the corners of the box rounded (with a radius of 2mm)? Thank you very much! Duncan
