[NTG-context] \everymath problem
Hi,
I use luatex 0.43 with yesterday's beta. Running
\everymath = {\displaystyle}
\starttext
${a\over b}$
\stoptext
results in
! Use of \dospecialabout doesn't match its definition.
l.4 ${a\over b
}$
Plain format under luatex has no problem here.
If I change \over to \times it runs with fonts changed
to roman (i.e, not math italics).
Thank you.
Eythan

taco and i looked into it (fearing big problems) but it's actually
normal; use
\everymath = \expandafter{\the\everymath \displaystyle}
or
\appendtoks \displaystyle \to \everymath
as (among other important things) \everymath does initialize \over

And with \frac it can be configured at context low level (why no key
for \setupmathematics?)
\chardef\mathfracmode=1 % 0=auto, 1=displaystyle, 2=textstyle,
3=scriptstyle, 4=scriptscriptstyle, 5=mathstyle
$\frac{a}{b}$
