Howto fit text into a box
by Uwe Koloska 11 Jun '08

11 Jun '08

Hello, for a CD-Cover I have to fit a given text into a fixed box. I have tried to achieve this with the help of mag-0010 "Good looking shapes" but was not successful :-( Can you help me with this? The conditions: - the text is of fixed length - the area is of given size (has a given ratio) - the text has to fit completely inside this area - the last line must be justified, too - the fontsize of the text is the variable that can be changed - I have the current minimal context installation and as an addition: - if possible the words should not be hyphenated at all or hyphenated at an arbitrary character without a hyphenation mark (the text consists of names) A possible algorithm (similar to the one from mag-0010) 1 start with a small box with the given ratio 2 fill the text into the box 3 if all text fits in with a small penalty we are ready 4 make the box a bit larger 5 goto 2 Unfortunately, I'm not able to understand the code from the mag nor can I code the algorithm in context ... I would appreciate any input on this problem! Thank you Uwe Koloska

Hi, When I run the example below (current beta, pdftex, live.contextgarden.net) the generated pdf does not contain any pictures. Any suggestion how to solve this? Or is the command obsolete? Thanks, B. Vogel %test.tex \startstaticMPfigure{center} draw fullcircle scaled 2cm ; dotlabel.bot(textext("(0,0)"),origin) ; \stopstaticMPfigure \startstaticMPfigure{radius} draw fullcircle scaled 2cm ; drawarrow (0,0)--(1cm,0) ; label.bot(textext("$r$"),(5mm,0)) ; \stopstaticMPfigure \starttext Circle centered \usestaticMPfigure[center][width=1cm] at origin with radius \usestaticMPfigure[radius][width=1cm] $r=1\,\text{cm}$. \stoptext

experimental feature
by Hans Hagen 11 Jun '08

11 Jun '08

Hi, I uploaded a beta with an experimental mkiv feature: fallback fonts. \starttext \definefontfallback [whatever] [Slanted] [0x0060-0x007F] \definefontfallback [whatever] [Bold] [0x0080-0x00FF,0x00A0-0x00AF] \definefontfallback [whatever] [BoldSlanted] [0x00C0-0x00C7] \definefontsynonym[SerifPlus][Serif][fallbacks=whatever] \definefont[MySerif][SerifPlus] \MySerif \dostepwiserecurse{0}{255}{1}{% {\tttf\uchexnumbers\recurselevel:}\char\recurselevel\hskip10pt plus 5pt\relax } \stoptext specifications like [Bold sa 1.2] also work Future versions will provide multiple fallbacks, conditional fallbacks etc. For insiders ... no virtual fonts are used which means that that in principle features still work ok. BTW, In this beta OSFONTDIR is set automatically when unset, on windows (tested by me) and on macosx (tested by mojca); other platforms can be dealt with when we know what to set.

Re: [NTG-context] Problem with TSV tables

Time; Decay per second; Errorlimits To be honest - I do not understand a single line in the database module. A really dirty future-incompatible workaround is to duplicate the line. The first one will be swallowed and the lecond one will be typeset, but that's a bug in the module. Hans? Taco? Why is the first line ignored? It worked OK some time ago, and nothing has changed in the module itself, so it's a complete mystery. > Thanks for helping me! > > By the way... you did for a month ago send a working gnuplot module that > is working with Luatex. After a computercrash I lost it. Can you send > that once again?? I guess this is the file I have sent you some time ago, but it doesn't work any more. I suspect that this portion of code is "broken" (LuaTeX doesn't create a new file any more), but I need to test before saying anything; it might be some completely reason: \doifmode{*\v!first}{ \immediate\openout\scratchwrite=\GNUPLOTfile.plt \immediate\write\scratchwrite{set terminal \@@GNUPLOToutput\space\@@GNUPLOToptions}% \immediate\write\scratchwrite{load '\GNUPLOTfile.tmp'}% \immediate\closeout\scratchwrite } I wanted to say: "a dirty workaround is to run texexec with mkii before" since it does generate the file (mkiv doesn't) and then luaTeX would use that file, but even that seems to be broken now. Just in case that Hans can spot the reason of error, here it is, but I will try to find some minimal example to reproduce it. !

new beta
by Hans Hagen 10 Jun '08

10 Jun '08

Hi, There is a new beta; apart from a few fixes (mostly mkiv) the mathml interpreter now also mathml 3 (for as much as I could deduce it from the draft which is definitely a draft and not yet a reference). Provisional openmath is also part of the game but not that well tested. Something that we call 'calcmath' is available by default when the module is loaded. At the context conference Aditya has to plug some of the holes in my math knowledge in order to reach perfection. I also uploaded a new mmlprime.pdf document. Although I need to do a major cleanup x-mathml shows a bit how to deal with xml in mkiv.

Problem with '\ ' in math commands in current minimals
by Morgan Brassel 10 Jun '08

10 Jun '08

Hi everyone, In the following example: \define[1]\com{com\ #1} \starttext \com{1} $\com{1}$ \stoptext the second call to \com (the one in math mode) seems to stop the compilation of the file. Is it a bug? It wasn't happening before. I'm using the latest minimals. Best regards, Morgan

Updating minimals

In theory mtxtools --script update [options] should work and it might make sense to provide something like context --update in future. (where options need to be at least --update --force, but --make and --delete is also suggested) But there's a little problem - luatex cannot be updated if you use mtxtools --script update. At least on windows, that definitely reports an error. Mojca

Arabic with LuaTeX vs. XeTeX
by Otared Kavian 10 Jun '08

10 Jun '08

Dear all, I just read the thread started by Burak Emir about "Typesetting Arabic today", and tried to typeset the sample sent by Idris Samawi Hamid. One of the Arabic or Persian fonts that I have and LuaTeX can find is Nadeem (working on Mac OS X 10.5.3), but what I get after typesetting is the following attached PDF: all the characters are typeset with their isolated form. However typestting the same text with XeConTeXt or XeTeX gives a nice result. So my question is, what should I add or subtract from the font features parameters to get a correct result? The source file is as follows: % engine=luatex \starttext \definefontfeature [test] [analyze=yes, mode=node, language=dflt, script=arab, aalt=yes, init=yes, medi=yes, fina=yes, isol=yes, liga=yes, mset=yes] \font\TradArabic = Nadeem*test at 18pt \startbuffer[paragraph] الحمدلله حمد معترف بحمده، مغترف من بحار مجده، بلسان الثناۤء شاكرا، ولحسن الاۤئه ناشرا؛ الذي خلق الموت والحيوة، والخير والشر، والنفع والضر، والسكون والحركة، والأرواح والأجسام، والذكر والنسيان. \blank اَلْحَمْدُ لِلّٰهِ حَمْدَ مُعْتَرِفٍ بِحَمْدِهٖ، مُغْتَرِفٌ مِنْ بِحَارِ مَجْدِهٖ، بِلِسَانِ الثَّنَاۤءِ شَاكِرًا، وَلِحُسْنِ اٰلاۤئِهٖ نَاشِرًا؛ اَلَّذِيْ خَلَقَ الْمَوْتَ وَالْحَيٰوةَ، وَالْخَيْرَ وَالشَّرَّ، وَالنَّفْعَ وَالضَّرَّ، وَالسُّكُوْنَ وَالْحَرَكَةَ، وَالْأَرْوَاحَ وَالْأَجْسَامَ، وَالذِّكْرَ وَالنِّسْيَانَ. \stopbuffer \start \TradArabic \pardir TRT \textdir TRT \getbuffer[paragraph] \stop \stoptext
