tuplet-bracket-interface

A bracket with a number in the middle, used for tuplets. When the bracket spans a line break, the value of break-overshoot determines how far it extends beyond the staff. At a line break, the markups in the edge-text are printed at the edges.

User settable properties:
bracket-flare (pair of numbers)
A pair of numbers specifying how much edges of brackets should slant outward. Value 0.0 means straight edges.
bracket-visibility (boolean or symbol)
This controls the visibility of the tuplet bracket. Setting it to false prevents printing of the bracket. Setting the property to if-no-beam makes it print only if there is no beam associated with this tuplet bracket.
break-overshoot (pair of numbers)
How much does a broken spanner stick out of its bounds?
connect-to-neighbor (pair)
Pair of booleans, indicating whether this grob looks as a continued break.
control-points (list)
List of offsets (number pairs) that form control points for the tie, slur, or bracket shape. For Béziers, this should list the control points of a third-order Bézier curve.
direction (direction)
If side-axis is 1 (or #X), then this property determines whether the object is placed #LEFT, #CENTER or #RIGHT with respect to the other object. Otherwise, it determines whether the object is placed #UP, #CENTER or #DOWN. Numerical values may also be used: #UP=1, #DOWN=-1, #LEFT=-1, #RIGHT=1, CENTER=0 but also other numerical values are permitted.
edge-height (pair)
A pair of numbers specifying the heights of the vertical edges: (left-height . right-height).
edge-text (pair)
A pair specifying the texts to be set at the edges: (left-text . right-text).
gap (dimension, in staff space)
Size of a gap in a variable symbol.
padding (dimension, in staff space)
Add this much extra space between objects that are next to each other.
positions (pair)
Pair of staff coordinates (left . right), where both left and right are in staff-space units of the current staff. LilyPond uses these values to select which slur candidate positions to use; if extreme positions are requested, LilyPond selects the closest positions.
shorten-pair (pair of numbers)
The lengths to shorten a text-spanner on both sides, for example a pedal bracket. Positive values shorten the text-spanner, while negative values lengthen it.
staff-padding (dimension, in staff space)
Maintain this much space between reference points and the staff. Its effect is to align objects of differing sizes (like the dynamic p and f) on their baselines.
thickness (number)
Line thickness, generally measured in line-thickness.
Internal properties:
note-columns (pair)
list of NoteColumn grobs.
tuplet-number (layout object)
the number for a bracket.
tuplets (unknown)
list of smaller tuplet brackets

This grob interface is used in the following graphical objects: LigatureBracket and TupletBracket
