I've been trying to set up a score where all empty staves _except one_ are
removed, and so have been experimenting with \RemoveEmptyStaves \override
VerticalAxisGroup #'remove-xxx. It's thrown up a few oddities which I
thought were worth pointing out, and it may be what I've found could be used
in the documentation.
First, trying this:
\layout {
\context {
\Staff
\override VerticalAxisGroup #'remove-first = ##t
\override VerticalAxisGroup #'remove-empty = ##t
}
}
which I thought might work, simply removes all staves from the score,
whether they're empty or not. I thought override VerticalAxisGroup
#'remove-empty = ##t might be a synonym for \RemoveEmptyStaves and so this
surprised me. It looks like a bug, although the usage isn't used in the
docs.
\layout {
\context {
\Staff
\RemoveEmptyStaves
\override VerticalAxisGroup #'remove-first = ##t
}
}
as expected, removes all empty staves correctly. To ensure that one staff
is not removed, code like this works well:
\new Staff {
\override Staff.VerticalAxisGroup #'remove-first = ##f
\override Staff.VerticalAxisGroup #'remove-empty = ##f
\clef "bass" R1*35
}
I think this could be documented in the docs. I don't think it's in the
LSR, but that's down at present and I can't check. The basic model that
seems to work best is to globally remove all empty staves, and then locally
turn that option back on in the staff definition.
