Splits container in two at given index position. Compare with split.container_fractured( )().
Both functions break container just before index. However, split.container_unfractured( ) preserves spanners. And split.container_fractured( ) fractures spanners.
Both functions create two new copies of container. Both functions empty original container of contents.
Return split parts.
Example of splitting a beamed triplet in voice:
t = Voice(FixedDurationTuplet((2, 8), construct.run(3)) * 2)
tuplet = t[1]
pitchtools.diatonicize(t)
Beam(t[:])
\new Voice {
\times 2/3 {
c'8 [
d'8
e'8
}
\times 2/3 {
f'8
g'8
a'8 ]
}
}
left, right = split.container_fractured(tuplet, 1)
\new Voice {
\times 2/3 {
c'8 [
d'8
e'8
}
\times 2/3 {
f'8 ]
}
\times 2/3 {
g'8 [
a'8 ]
}
}
