Hi Hans,
Thank you for the new upload and the rewriting of the math fonts stuff, thanks also to Mikael S. I did several tests on real size math projects and did not notice important issues.
The two issues I noticed, show up mainly with LucidaOT, and are explained in the following example:
\setupbodyfont[lucidaot]
\definemathstackers[MySymbol]
[voffset=-1.4\mathexheight, % -.8\mathexheight
hoffset=\zeropoint,
mathclass=ord,
topoffset=.3\mathemwidth, % poor man's italic correction
middlecommand=\mathematics]
\define[1]\interior{\mathover[MySymbol]{176}{#1}} %2218 U+00B0
\definemathcommand [Argmin] [limop] {\mfunctionlabeltext{ArgMin}}
\definemathcommand [liminfbar] [limop] {\underline{\mfunctionlabeltext{lim}}}
\definemathcommand [limsupbar] [limop] {\overline{\mfunctionlabeltext{lim}}}
\starttext
If $A \subset {\Bbb R}$ is a set, its interior is denoted by $\interior{A}$. Can one have the circle over $A$ slightly bigger (probbaly this is font dependent)?
The built-in commands $\liminf$ and $\limsup$ do not work properly with LucidaOT (I tried other fonts and there they are fine):
\startformula
x_{n} := (-1)^n, \quad\mbox{then} \quad \liminf_{n \geq 0}x_{n} = -1, \quad \limsup_{n\geq 0} x_{n}= +1.
\stopformula
The commands defined above, \type{\liminfbar} and \type{\limsupbar}, behave correctly in all fonts I tested:
\startformula
x_{n} := (-1)^n, \quad\mbox{then} \quad \liminfbar_{n \geq 0}x_{n} = -1, \quad \limsupbar_{n\geq 0}x_{n} = +1,
\stopformula
but not the command \type{\Argmin} (which does not show Argmin in any font…)
\startformula
\Argmin_{x\in {\Bbb R}} (x^2 - x + 1) = {1 \over 2}.
\stopformula
