New in version 2.0.
Get composite offset difference series from leaves in expr:
abjad> staff_1 = Staff([tuplettools.FixedDurationTuplet(Duration(4, 8), notetools.make_repeated_notes(3))])
abjad> staff_2 = Staff(notetools.make_repeated_notes(4))
abjad> score = Score([staff_1, staff_2])
abjad> pitchtools.set_ascending_named_diatonic_pitches_on_nontied_pitched_components_in_expr(score)
abjad> f(score)
\new Score <<
\new Staff {
\fraction \times 4/3 {
c'8
d'8
e'8
}
}
\new Staff {
f'8
g'8
a'8
b'8
}
>>
abjad> leaftools.get_composite_offset_difference_series_from_leaves_in_expr(score)
[Offset(1, 8), Offset(1, 24), Offset(1, 12), Offset(1, 12), Offset(1, 24), Offset(1, 8)]
Composite offset difference series defined equal to time intervals between unique start and stop offsets of leaves in expr.
Return list of fractions.
