switching to a different math font (with alternatives) in the middle of document
Hello, I'm just wonderding if there is a way to switch to an OpenType Math font (referred to by name or filename, without any predefined typescript) with some stylistic alternative in the middle of the document, like in the LaTeX example: running text ... \setmathfont[Scale=0.86,StylisticSet=4]{Lucida Bright Math OT} $\mathcal{ABC XYZ}$~(StylisticSet=4) ... running text ... \setmathfont{Asana Math} $\mathfrak{ABC XYZ\,abc xyz}$ or do I always need to provide a predefined typescript? How does one switch between stylistic alternatives for math? I have a problem with {\switchtobodyfont[asana] $\mathscript ABC XYZ\,abc xyz$} and I also need to figure out how to get "math bold italic sans serif greek alphabet". Any hints welcome. Thank you, Mojca

You must not be using the same editor (and TeX) as Mojca :) Alan

Sure, when Khaled added alternates to xits we also added support for it to mkiv. \setupbodyfont[xits] \starttext \unexpanded\def\mathaltcal{\mathalternate{cal}\cal} $ABC$ $\cal ABC$ $\mathalternate{cal}\cal ABC$ $\mathaltcal ABC$ \stoptext As this can differ per font, we use symbolic names, and these are defined in the lfg files. This functionality is there already for some time but probably not wikified (there are examples in the test suite).

\setupbodyfont[xits]
But this requires a whole typescript. So there is no way to say something equivalent to \font\a=Asana-Math.otf \a without the need to create a lfg file & so on? Anyway, your example with Asana broke a compilation, so at least I was able to realize that I was missing the otf font, whereas yesterday it was simply ignoring the fact that the font was missing and has typeset everything in TeX Gyre I think.
\starttext
\unexpanded\def\mathaltcal{\mathalternate{cal}\cal}
And how do I know what is an equivalent of StylisticSet=4 in Lucida? Would this be something like italic = { feature = 'ss01', value = 1, comment = "Mathematical Alternative Italic" }, where \mathalternate{italic} works as +ss01, but the ss04 not because it has not been defined in lucida-opentype-math.lfg?
$ABC$ $\cal ABC$ $\mathalternate{cal}\cal ABC$ $\mathaltcal ABC$

Why? It's a dynamic feature. It's just that we use nicer names than ss01 and such.

I'm not sure what you mean here. You can use \font directly but it has no benefits as it's not part of a proper math setup then.
Anyway, your example with Asana broke a compilation, so at least I was able to realize that I was missing the otf font, whereas yesterday it was simply ignoring the fact that the font was missing and has typeset everything in TeX Gyre I think.
I never used Asana.
\starttext
\unexpanded\def\mathaltcal{\mathalternate{cal}\cal}

Well, that's just ss04 but referring to a stylistic set at the user level is a bad idea as that's not standardized
Would this be something like italic = { feature = 'ss01', value = 1, comment = "Mathematical Alternative Italic" },
Indeed.
where \mathalternate{italic} works as +ss01, but the ss04 not because it has not been defined in lucida-opentype-math.lfg?
Indeed, although of course I could make it honor the fuzzy ss01 etc variants too but no one can guarantee that these ss's always stay the same. In principle we can even define commands automatically if needed but then switching to a different font setup in a document can result in unknown commands. After all, there can be 10 different alternate scripts in one font and zero in another.
$ABC$ $\cal ABC$ $\mathalternate{cal}\cal ABC$ $\mathaltcal ABC$
\stoptext
Once the dust around math fonts has settled we might end up with some standardization in mkiv with respect to the tags used in the lfg files.
