Hi Hans,
Thanks for the quick fix of today's upload.
I could typeset your examples with \mathopen, \mathclose and these are great
features in order to fine tune the spacing in math mode.
Regarding the new command \Uover, I thought maybe it would be more consistent
to have the usual structure
${1} \Uover {2}$
like the more friendly ${1} \over {2}$ instead of having
That would involve backtracking and be a psin in the butt wrt control.
One can't have it all.
$\Uover{1}{2}$
which is more like the \frac structure.
Watch out: these are low level primitives (it is actually a set of
primitives that put stuff on top of each other). The \frac is the
interfaced variant.
Also a structure like
$\Uover style \textstyle{1}{2}$
seems a little bit far from the usual ConTeXt atmposphere… Would it not be
possible to have
${1} \Uover[style=textstyle] {2}$
instead?
That is what we have frac for (and one can define veriants that have set
styles).
In any case, thanks a lot for the constant addition of cute features…
Some of these engine level extensions have been on my list for a while
and eventually make implementing the user interfaced wrappers nicer (and
sometimes more robust). Some is actually possible because some engine
internals are a bit reorganized.
