3.1.62 LeftEdge

LeftEdge objects are created by: Break_align_engraver.

Standard settings:

break-align-anchor (number):

ly:break-aligned-interface::calc-extent-aligned-anchor

Grobs aligned to this break-align grob will have their X-offsets shifted by this number. In bar lines, for example, this is used to position grobs relative to the (visual) center of the bar line.

break-align-symbol (symbol):

'left-edge

This key is used for aligning and spacing breakable items.

break-visibility (vector):
#(#f #f #t)

A vector of 3 booleans, #(end-of-line unbroken begin-of-line). #t means visible, #f means killed.

non-musical (boolean):

#t

True if the grob belongs to a NonMusicalPaperColumn.

space-alist (list):
'((ambitus extra-space . 2.0)
  (breathing-sign minimum-space . 0.0)
  (cue-end-clef extra-space . 0.8)
  (clef extra-space . 0.8)
  (cue-clef extra-space . 0.8)
  (staff-bar extra-space . 0.0)
  (key-cancellation extra-space . 0.0)
  (key-signature extra-space . 0.8)
  (time-signature extra-space . 1.0)
  (custos extra-space . 0.0)
  (first-note fixed-space . 2.0)
  (right-edge extra-space . 0.0))

A table that specifies distances between prefatory items, like clef and time-signature. The format is an alist of spacing tuples: (break-align-symbol type . distance), where type can be the symbols minimum-space or extra-space.

X-extent (pair of numbers):
'(0 . 0)

Extent (size) in the X direction, measured in staff-space units, relative to object’s reference point.

Y-extent (pair of numbers):
'(0 . 0)

Extent (size) in the Y direction, measured in staff-space units, relative to object’s reference point.

This object supports the following interface(s): break-aligned-interface, grob-interface and item-interface.
