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.

glyph (string):
|

a string determining what (style) of glyph is typeset. Valid choices depend on the function that is reading this property.

break-glyph-function (procedure):
default-break-barline

This function determines the appearance of a bar line at the line break. It takes a glyph and break-direction and returns the glyph at a line break.

bar-size-procedure (procedure):
Bar_line::get_staff_bar_size

Procedure that computes the size of a bar line.

print-function (procedure):
Bar_line::print

Function taking grob as argument, returning a Stencil object.

break-visibility (procedure):
all-visible

A function that takes the break direction and returns a cons of booleans containing (transparent . empty). The following variables are predefined: all-visible, begin-of-line-visible, end-of-line-visible, begin-of-line-invisible, end-of-line-invisible, all-invisible.

breakable (boolean):
#t

Can this object appear at a line break, like clefs and bar lines?

before-line-breaking-callback (procedure):
Bar_line::before_line_breaking

This procedure is called before line breaking, but after splitting breakable items at potential line breaks.

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) (first-note fixed-space . 1.3) (next-note semi-fixed-space . 1.3) (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 line, 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):
1.6

Thickness of the thin line in a bar line.

thick-thickness (number):
6.0

Bar line thickness, measured in linethickness.

This object supports the following interfaces: font-interface, break-aligned-interface, item-interface, bar-line-interface and grob-interface
