Also, all math related data is collected in tables in such a way that we can at some point add more advanced support, like domain specific rendering (and symbols) which is currently seldom part of tex math implementations. Feel free to ask for all you have been missing in math so far. We're not that bound to traditional approaches.

error with footnotes blackrule
by Steffen Wolfrum 21 Feb '10

21 Feb '10

Hi, todays minimal gives an error: Runaway argument? \letvalue {\??vn \c!rule :c:\currentnote }\normalnoterule , \v!normal \ETC. ! File ended while scanning use of \p!compareprocessactionD. <inserted text> \par <*> ./notetext.tex ? The cause is "\blank[2mm]" in this example: \def\MyRule{\blackrule[width=18mm,height=0.4pt]\blank[2mm]} \setupfootnotes [rule=\MyRule] This harmless vertical space did it up to now. What's the phrase that should be chosen instead? Steffen

Hi, The latest beta has a few more fonts defined in type-otf.mkiv. YOu can do things like \setupbodyfont[mscore,ss,10pt] \setupbodyfont[liberation,rm,10pt] as mscore and liberations are yet unknown the related typescript will be loaded automatically (new feature).

Left, right, top, bottom margins in a \framed box
by Oliver Buerschaper 21 Feb '10

Dear all, I'm wondering how I can get different margins between the contents of a framed box and its left, right, top or bottom border. Somehow "offset" affects all margins simultaneously ... Best wishes, Oliver

type-loc.tex
by Hans van der Meer 20 Feb '10

20 Feb '10

For some reason running mkiv-beta needs the presence of a file ..tex/context/user/type-loc.tex If I remove the file I get a complaint of not being able to find this file. Is the file absolutely required or could it be some remnant in some cache that causes the request? Hans van der Meer

Thanks, Wolfgang! This works really fine \setupinterlinespace[height=0.55,depth=0.45,line=38pt] \definedelimitedtext [example] [spacebefore={\strutdepth,none}, spaceafter=none, style=\tfx, before={\setupinterlinespace[line=16pt]}] B.R. Vyatcheslav

I have now manually downloaded the mathdesign fonts (and the charter fonts, not available on the server it seems) The fonts gets used, but I get upright math letters instead of italic ones. My test file is given by \definetypeface[charter][rm][serif][charter] [default] \definetypeface[charter][mm][math] [charter] [default] \setupbodyfont[charter,10pt] \starttext We define, for real $x$, the absolute value of $x$ as \startformula |x|= \startcases \NC \hphantom{-}x \MC x\geq 0,\NR \NC -x \MC x<0.\NR \stopcases \stopformula Also let $\alpha$, $\beta$ and $\Gamma$ be\dots \stoptext The output can be found at http://home.imf.au.dk/mickep/mdesign.pdf Typesetting a similar document with LaTeX I get italic math (note also that the \Gamma is upright, I guess that this is an option that is turned on by default by LaTeX) http://home.imf.au.dk/mickep/lmdesign.pdf I guess this has something to do with the following lines in math-vfu.lua mathematics.make_font ( "charter-math", { { name = "file:bchr8a", features = "virtualmath", main = true }, -- { name = "md-chr7m.tfm", vector = "tex-mr" }, { name = "md-chri7m.tfm", vector = "tex-mi", skewchar=0x7F }, { name = "md-chri7m.tfm", vector = "tex-it", skewchar=0x7F }, { name = "md-chr7y.tfm", vector = "tex-sy", skewchar=0x30, parameters = true }, { name = "md-chr7v.tfm", vector = "tex-ex", extension = true }, { name = "msam10.tfm", vector = "tex-ma" }, { name = "msbm10.tfm", vector = "tex-mb" }, } ) However, I am not able guess what to change (I tried different things available in mdbch.map). Any help is appreciated. Mikael
