Comment #47 on issue 3560 by [email protected]: Completion_heads_engraver with
\scaleDurations
http://code.google.com/p/lilypond/issues/detail?id=3560
A music function has no notion of the starting time. You can do
{ r8 \scaleDuration ... }
In a somewhat better situation are music functions run at scorification
time. But this kind of job (labelling music expressions with factors or
whatever) would likely be best situated with an iterator: an iterator has
an authoritive notion of timing and works on music expression rather than
stream events. But iterators don't have scoped variables like contexts
have, so you probably have to copy the whole content before labelling it
and and iterating into it (iterators are not supposed to change music
expressions).
But you'd still want to use an _engraver_ for the actual splitting itself
since you often want to limit that kind of action to single contexts.
And then we get something that is nice as long as it works in its
envisioned use case, and unmaintainably complex to handle for the user when
it doesn't.
I don't see the point.
