grace_corner_cases¶
CORNER CASE 1.
Before-grace-to-on-beat-grace works correctly when before-grace container is attached first:
>>> music_voice = abjad.Voice("c'4 d' e' f'", name="MusicVoice")
>>> container = abjad.BeforeGraceContainer("gs'16")
>>> abjad.attach(container, music_voice[1])
>>> container = abjad.on_beat_grace_container(
... "a'8 b' c'' b'", music_voice[1:3], grace_leaf_duration=(1, 24)
... )
>>> abjad.attach(abjad.Articulation(">"), container[0])
>>> staff = abjad.Staff([music_voice])
>>> lilypond_file = abjad.LilyPondFile([r'\include "abjad.ily"', staff])
>>> abjad.show(lilypond_file)
Before-grace-to-on-beat-grace works correctly when on-beat grace container is attached first:
