Hi Hans,
Thanks for the new feature in \setupmathematics.
I did some testing of the feature on a several documents, , and followed the discussions you had with Aditya and Wolfgang.
Everything works fine, except that when one tries to modify, for instance the definition of \liminf (in order to have it as an underlined lim), ConTeXt reports an error.
Please see below the minimal example and the error message.
In the minimal example if you uncomment the lines modifying the definition of \liminf on gets an error message.
%%%% begin test-functionstyle.tex
\setupmathematics
[functionstyle=\ss,
functioncolor=red]
%\unprotect
%\definemathcommand [liminf] [limop] {\underline\mfunctionlabeltext{lim}}
%\protect
\starttext
\startformula
f = \sin i\omega x^{\sin(x^{\sin(y)})}
\stopformula
Fatou's lemma implies
\startformula
\int_{\Omega}\liminf_{n\to\infty} (1+\cos(n|x|))dx \leq \liminf_{n\to\infty}\int_{\Omega}(1+\cos(n|x|))dx.
\stopformula
\stoptext
%%%% end test-functionstyle.tex
The error message is:
\begingroup
\mfunctionlabeltext #1->\begingroup
\math_tags_mfunctionlab {#1}\c_apply_fun...
\483>limop #1->\mathop {#1
}
l.45 \int_{\Omega}\liminf
_{n\to\infty} (1+\cos(n|x|))dx \leq \liminf_{n\to\inf...
Best regards: OK
