I just had an idea. Why not make afterGraceFraction a context property
for Score? Wouldn't that solve all of these problems?
I'm actually not sure -- let me know.
No, afterGrace does not work like that. It's music function, so it
runs before contexts are created.
Bummer.
Sorry if I'm being dim here, Han-Wen, but I thought after
afterGraceFraction was a way of over-riding the default spacing for
grace notes if you want the the grace notes to appear at some point
other than the spacing of 3/4 of the value of the note to which the
\aftergrace expression is attached. So it's basically a parameter
setting for afterGrace.
At the moment it looks like we're setting the equivalent of a global
static variable to do this - bad news for such a specific function.
Is there a way of do this sort of thing sometime in the future?
\afterGrace {d1 {c16[ d] }} % works as now - except extra braces
\afterGrace {d1 {c16[ d] } 15 16} % extra two optional parameter does
the biz currently done by
#(define afterGraceFraction (cons 15 16))
c1 \afterGrace d1 { c16[ d] } c1
We get the parser to throw a fit if there are any other than two
optional parameters or none, or if they are both there and they aren't
both numeric.
Does the same restriction re contexts apply to output-suffix? Could we
make *that* a property setting for a \book block?
Cheers,
Ian
