[NTG-context] Mixing math and text font
Dear list, in my math, I would like one font (the text font) to be used for letters and digits and another font (the math font) to be used for mathematical symbols. I have tried it like that: % Example 1 \usemodule[simplefonts][size=40pt] \setmathfont[termes] \setmainfont[latinmodernroman] \starttext 123\\$ 123 \coprod \leftrightarrow $ \stoptext % Example 2 \definetypeface [fonttest] [rm][serif] [modern] \definetypeface [fonttest] [mm][math] [termes] \setupbodyfont[fonttest, 40pt] \starttext 123\\$ 123 \coprod \leftrightarrow $ \stoptext In both examples, the math font is used for the whole formula. How can I mix the fonts? Kind regards and best wishes for 2014, Joshua Krämer ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___

Can you elaborate what do you mean by 'mix the fonts'? What output do you want to get. For the text font I use (it's a commercial typeface), a matching math font doesn't exist. Now if I use for example Termes as the math font, the formulae don't match the regular text, because the letters and digits differ. That's why I want in the formulae math symbols like special arrows and operators to be taken from Termes, but regular alphanumeric characters from my text font. So in my minimal examples, 123 should look the same in the text and the formula.

Thanks for your answer. I already use context standalone, but even after
an update (first-setup.sh), the fonts are not mixed. What are the
additional steps to do?
You have to switch from the simplefonts module to the new fontfamily
command (a new built-in system which replaces simplefonts) to set
the fonts for your document.
The fourth argument specifies which part of the font you want to replace
(you could also have written [preset=math:lowercaseitalic] instead of
[math:lowercaseitalic]).
\definefontfamily [mainface] [rm] [Latin Modern Roman]
\definefallbackfamily [mainface] [mm] [Latin Modern Roman]
[math:lowercaseitalic]
\definefontfamily [mainface] [mm] [TeX Gyre Termes Math]
\setupbodyfont[mainface]
\starttext
TeX uses different fonts for text and math, e.g. \math{f(x)=x^2+2x+4} but it
possible to replace certain characters in the math font with glyphs from a text
font.

[NTG-context] Malayalam shaping with mkiv/LuaTeX
Hello, especially Hans and Kai,
I have succeeded to an extent in adding Malayalam shaping to the
existing Devanagari shaping. Being a complete novice in Lua and mkiv,
I'm at a point where your expertise is needed to proceed further.
Please find the attached patch, test case listed below and expected
rendering for comparison. Additionally needed to support:
1. Decomposing 2 part Matras (dependent vowels) - 0D4A, 0D4B, 0D4C
for Malayalam [Test cases 2 4]. This is needed (at least) for Tamil
also. I guess it is as simple as replacing one code point with 2
others - example: replace 0D4A with 0D46, 0D3E. See page 3 of this
Unicode standard: http://www.unicode.org/charts/PDF/U0D00.pdf
2. Handling pref opentype feature for v2 opentype spec (script tag
mlm2). This is required for Malayalam Ra ligature, the glyph is
formed correctly but it needs to be reordered as pre-base to the base
syllable [Test case 1]. (Note that the old spec mlym handles Ra
form as pstf and no reordering required). You can observe the
difference in Test case 5 - Ra form should be attached to first
consonant instead of second one (mlm2 needs glyph formed by
Virama+Ra to be reordered as pre-base to first consonant, while mlym
doesn't need to).
3. Handling pstf opentype feature. It works mostly [Test case 8],
except when a post-base Matra follows [Test case 9].
4. Test cases 6 7 shows an example where glyph formation fails when
a pstf Ya follows. This works correctly with some other conjuncts,
though.
4. font-odv.lua hard coded Devanagari Virama (094D) and Ra (0930) in
certain places, which needs to use table values to handle other
scripts.
5. I had to change methods.deva to methods.mlym and methods.dev2
to methods.mlm2 to get this working, not sure how best to handle
multiple scripts.
6. There are other cases like Dot-reph (0D4E) which uses GPOS table
and requires reordering as post-base to the syllable follows it, but I
haven't looked into them yet.
i) The font used is Rachana, which supports both mlm2 and mlym
specs, can be downloaded from here:
http://download.savannah.gnu.org/releases/smc/fonts/malayalam-fonts-6.0/Rachana/Rachana.ttf
You can switch to mlm2 and mlym in test case.
