[ ]

Usage

1. Example

   a = FoscStaff(FoscLeafMaker().(#[60,62,64,65], 1/4));
   x = FoscStartTextSpan(
       leftText: FoscMarkup('pont.').upright,
       rightText: FoscMarkup('tasto').upright,
       style: 'solidLineWithArrow'
   );
   a[0..].textSpanner(x);
   a.show;

   

2. Strings are automatically wrapped as markups.

   a = FoscStaff(FoscLeafMaker().(#[60,62,64,65], 1/4));
   x = FoscStartTextSpan("pont.", "tasto", 'solidLineWithArrow');
   a[0..].textSpanner(x);
   override(a).textSpanner.staffPadding = 4;
   a.show;

   

3. Enchained spanners.

   a = FoscStaff(FoscLeafMaker().(#[60,62,64,65,nil], 2/4));
   x = FoscStartTextSpan("pont.", style: 'solidLineWithArrow');
   a[..2].textSpanner(x);
   x = FoscStartTextSpan("tasto", "pont.", 'solidLineWithArrow');
   a[2..].textSpanner(x);
   override(a).textSpanner.staffPadding = 4;
   a.show;

   

   a.format;
