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 symbols minimum-space or extra-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.
