Hi,
I see in the LuaTeX the \Uoverdelimiter and \Uunderdelimiter commands.
Is there a sensible/peferred way to create a mathematics fraction that
uses a particular glyph for the horizontal rule between the numerator
and denominator?
(to be clear I am looking for a command that acts like \frac{a}{b} not
like the a/b that one can get with \Uskewed)
Thanks in advance!
Fractions are (tex) rule based. Using glyphs instead is possible in
luametatex (delimiter based), also for other constructs like radicals,
but then one also has to set up the fonts and add quite a bit of code
all over the place.
These kind of features are supported by ConTeXt so not that relevant for
this list. Adding features like this to LuaTeX is too tricky as it might
(temporary) break something out of our scope (which is why luatex is
basically frozen).
