layouttools.set_line_breaks_cyclically_by_line_duration_ge

abjad.tools.layouttools.set_line_breaks_cyclically_by_line_duration_ge.set_line_breaks_cyclically_by_line_duration_ge(expr, line_duration, klass=<class 'abjad.tools.measuretools.Measure.Measure.Measure'>, adjust_eol=False, add_empty_bars=False)

Iterate klass instances in expr and accumulate prolated duration. Add line break after every total less than or equal to line_duration:

abjad> from abjad.tools import layouttools

abjad> t = Staff(Measure((2, 8), notetools.make_repeated_notes(2)) * 4)
abjad> pitchtools.set_ascending_named_diatonic_pitches_on_nontied_pitched_components_in_expr(t)
abjad> f(t)
\new Staff {
    {
        \time 2/8
        c'8
        d'8
    }
    {
        \time 2/8
        e'8
        f'8
    }
    {
        \time 2/8
        g'8
        a'8
    }
    {
        \time 2/8
        b'8
        c''8
    }
}

abjad> layouttools.set_line_breaks_cyclically_by_line_duration_ge(t, Duration(4, 8))
abjad> f(t)
\new Staff {
    {
        \time 2/8
        c'8
        d'8
    }
    {
        \time 2/8
        e'8
        f'8
        \break
    }
    {
        \time 2/8
        g'8
        a'8
    }
    {
        \time 2/8
        b'8
        c''8
        \break
    }
}

Set adjust_eol to True to include a magic Scheme incantation to move end-of-line LilyPond TimeSignature and BarLine grobs to the right.

Changed in version 2.0: renamed layout.line_break_every_prolated() to layout.set_line_breaks_cyclically_by_line_duration_ge().
