not defined at all (yet) (see end of math-vfu for how to do that; you can
give lucida a try)
I tried that, but it seems not enough to define:
mathematics.make_font ( lucida-math, {
{ name = lucidabright, features = virtualmath, main = true },
{ name = lucidanewmathroman, vector = traditional-mr } ,
{ name = lucidanewmathitalic, vector = traditional-mi, skewchar=0x7F
},
{ name = lucidanewmathsymbol, vector = traditional-sy,
skewchar=0x30, parameters = true } ,
{ name = lucidanewmathextension, vector = traditional-ex, extension
= true } ,
{ name = msam10, vector = traditional-ma },
{ name = msbm10, vector = traditional-mb },
} )
(I don't know in which of the lucida fontfiles the symbols a and b are
located.)
I would be glad to test math for the good old LucidaBright fonts.
I'm not smart enough to prepare this myself.
Cambria has a very ugly spacing.
hm, do you have the latest cambria? there might be problems with some otf
math parameters but we need examples before we can act on that
I had an old version of cambria cached in
C:\contextminimal\texmf-cache\luatex-cache\context\...\fonts
After deleting them spacing is ok. But the \bigotimes operator from my
example file now disappeared.
btw. in the wiki is described a ConTeXt command \showmathcharacters.
This seems not to work anymore. The related file math-run.tex is not
input at the time of format generation.
in mkiv we wil use modules for that ... s-fnt-25 is for math
Should I send the output of:
\usetypescript[cambria]
\setupbodyfont[cambria]
\usemodule[fnt-25]
\starttext
\showmathfontcharacters
\stoptext
to somebody? (130 pages, 458 kB)
P.S. will the key [texnansi] (or [ec]) remain necessary to switch to
LucidaBright?
no

Hi Hans, hi Taco, hi all,
testing math with the latest ConTeXt beta i found some problems.
My test file is:
\usetypescriptfile[type-buy]
\def\currentfontname
{\ctxlua{tex.print(font.getfont(font.current()).fullname)}}
\starttext
\startbuffer[mathbuffer]
\currentfontname
$a^2 + b^2 = c^2$
$E = mc^2 \bigotimes \sum$
$α^2 + β^2 = γ^2$
\blank[big]
\stopbuffer
\getbuffer[mathbuffer]
\usetypescript[lucida][texnansi]
\setupbodyfont[lucida]
\getbuffer[mathbuffer]
\usetypescript[cambria]
\switchtotypeface[cambria]
\getbuffer[mathbuffer]
\usetypescript[palatino]
\switchtotypeface[palatino]
\getbuffer[mathbuffer]
\stoptext
For using old type-1 math fonts, you need to create virtual fonts.
Latin Modern and Palatino/px work very fine.
For LM, Palatino, and Times, the virtual fonts are created in math-vfu.lua
Lucida lacks greek and some operators. I found no embedded LucidaNewMath
fonts
in the resulting pdf.
There are no virtual fonts for Lucida math. In principle, one just needs
to translate math-lbr to lua syntax. I will try to do that, but I need
someone to test the results, since I do not have Lucida fonts myself.
Cambria has a very ugly spacing.
Luatex does not do kerning for utf math right now. This will be handled
correcrly in the future.
btw. in the wiki is described a ConTeXt command \showmathcharacters.
This seems not to work anymore. The related file math-run.tex is not
input at the time of format generation.
\ShowCompleteFont{name:Cambria-Math}{10pt}{1}
P.S. will the key [texnansi] (or [ec]) remain necessary to switch to
LucidaBright?
For text fonts, yes. Normally math fonts use an independent encoding.

Re: [NTG-context] math problems
fairly recently as in, say, 2 months ago, i could typeset that file without changing anything, that is, it worked with luatex and pdftex from the minimals and pdtex from texlive 2008. is this because of the recent addition of the math stuff?
