3.1.53 LeftEdge
LeftEdge objects are created by: Break_align_engraver.
Standard settings:
break-align-symbol
(symbol):
'left-edge
This key is used for aligning and spacing breakable items.
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.
X-extent
(pair of numbers):
'(0 . 0)
Hard coded extent in X direction.
non-musical
(boolean):
#t
True if the grob belongs to a
NonMusicalPaperColumn
.break-visibility
(vector):
#(#t #f #t)
A vector of 3 booleans,
#(end-of-line unbroken begin-of-line)
.#t
means visible,#f
means killed.space-alist
(list):
'((custos extra-space . 0.0) (ambitus extra-space . 2.0) (time-signature extra-space . 1.0) (staff-bar extra-space . 0.0) (breathing-sign minimum-space . 0.0) (clef extra-space . 0.8) (first-note fixed-space . 2.0) (right-edge extra-space . 0.0) (key-signature extra-space . 0.0) (key-cancellation 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 symbolsminimum-space
orextra-space
.
This object supports the following interface(s): item-interface, break-aligned-interface and grob-interface.
