attach

!!!TODO: attaches to FoscComponents and FoscSelections? can this method be moved lower in the tree? !!! if not, then add a test for a valid receiver type to the top of the method.

    a = FoscHairpin('p < f'); // FIXME class not defined 
b = FoscLilypondTweakManager();

    b = a.selectLogicalTies(nontrivial: true);
b.do { |each| each.items.collect { |each| each.cs }.postln };
    FoscSelection([ FoscLogicalTie([ FoscNote(FoscPitch("C4"), FoscDuration(1, 4)), FoscNote(FoscPitch("C4"), FoscDuration(1, 16)) ]), FoscLogicalTie([ FoscNote(FoscPitch("E4"), FoscDuration(1, 4)), FoscNote(FoscPitch("E4"), FoscDuration(1, 4)) ]) ])

  6. Select trivial logicalTies

    b = a.selectLogicalTies(nontrivial: false);
b.do { |each| each.items.collect { |each| each.cs }.postln };
    FoscSelection([ FoscLogicalTie([ FoscNote(FoscPitch("D4"), FoscDuration(1, 8)) ]), FoscLogicalTie([ FoscRest(FoscDuration(1, 8)) ]) ])

  7. Select logicalTies in reverse order

    b = a.selectLogicalTies(reverse: true);
b.do { |each| each.items.collect { |each| each.cs }.postln };
    FoscSelection([ FoscLogicalTie([ FoscNote(FoscPitch("E4"), FoscDuration(1, 4)), FoscNote(FoscPitch("E4"), FoscDuration(1, 4)) ]), FoscLogicalTie([ FoscRest(FoscDuration(1, 8)) ]), FoscLogicalTie([ FoscNote(FoscPitch("D4"), FoscDuration(1, 8)) ]), FoscLogicalTie([ FoscNote(FoscPitch("C4"), FoscDuration(1, 4)), FoscNote(FoscPitch("C4"), FoscDuration(1, 16)) ]) ])


selectRuns

Select runs.

  1. Attach horizontal bracket to each run.

    a = FoscStaff(FoscLeafMaker().(#[60,60,62,nil,64,64], [1/4,1/24,1/12,1/8,1/4,1/4]));
a.consistsCommands.add('Horizontal_bracket_engraver');
m = a.selectLeaves;
tie(m[0..1]);
tie(m[4..]);
a.selectRuns.do { |each| each.horizontalBracket(tweaks: #[['direction', 'up']]) };
a.show;
