3.1.11 BarLine
BarLine objects are created by: Bar_engraver.
Standard settings:
break-align-symbol
(symbol):
'staff-bar
This key is used for aligning and spacing breakable items.
break-align-anchor
(number):
ly:bar-line::calc-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.
glyph
(string):
"|"
A string determining what ‘style’ of glyph is typeset. Valid choices depend on the function that is reading this property.
gap
(dimension, in staff space):
0.4
Size of a gap in a variable symbol.
layer
(integer):
0
The output layer (a value between 0 and 2): Layers define the order of printing objects. Objects in lower layers are overprinted by objects in higher layers.
break-visibility
(vector):
bar-line::calc-break-visibility
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
.stencil
(unknown):
ly:bar-line::print
The symbol to print.
bar-size
(dimension, in staff space):
ly:bar-line::calc-bar-size
The size of a bar line.
allow-span-bar
(boolean):
#t
If false, no inter-staff bar line will be created below this bar line.
space-alist
(list):
'((time-signature extra-space . 0.75) (custos minimum-space . 2.0) (clef minimum-space . 1.0) (key-signature extra-space . 1.0) (key-cancellation extra-space . 1.0) (first-note fixed-space . 1.3) (next-note semi-fixed-space . 0.9) (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 symbolsminimum-space
orextra-space
.kern
(dimension, in staff space):
3.0
Amount of extra white space to add. For bar lines, this is the amount of space after a thick line.
thin-kern
(number):
3.0
The space after a hair-line in a bar line.
hair-thickness
(number):
1.9
Thickness of the thin line in a bar line.
thick-thickness
(number):
6.0
Bar line thickness, measured in
line-thickness
.
This object supports the following interface(s): item-interface, font-interface, break-aligned-interface, bar-line-interface and grob-interface.
