Move parentage, children and spanners from components to empty container:
abjad> voice = Voice(Container("c'8 c'8") * 3)
abjad> pitchtools.set_ascending_named_diatonic_pitches_on_nontied_pitched_components_in_expr(voice)
abjad> spannertools.BeamSpanner(voice.leaves)
BeamSpanner(c'8, d'8, e'8, f'8, g'8, a'8)
abjad> f(voice)
\new Voice {
{
c'8 [
d'8
}
{
e'8
f'8
}
{
g'8
a'8 ]
}
}
abjad> tuplet = Tuplet(Fraction(3, 4), [])
abjad> containertools.move_parentage_children_and_spanners_from_components_to_empty_container(voice[:2], tuplet)
abjad> f(voice)
\new Voice {
\fraction \times 3/4 {
c'8 [
d'8
e'8
f'8
}
{
g'8
a'8 ]
}
}
Return none.
Changed in version 2.0: renamed scoretools.donate() to containertools.move_parentage_children_and_spanners_from_components_to_empty_container().
