BarLine objects are created by: Bar_engraver
Standard settings:
break-align-symbol(symbol):'staff-barThis key is used for aligning and spacing breakable items.
break-align-anchor(number):ly:bar-line::calc-anchorGrobs aligned to this break-align grob will have their X-offsets shifted by this number. In barlines, for example, this is used to position grobs relative to the (visual) center of the barline.
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):0.4Size of a gap in a variable symbol.
layer(number):0The 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-visibilityA vector of 3 booleans,
#(end-of-line unbroken begin-of-line).#tmeans visible,#fmeans killed.non-musical(boolean):#tTrue if the grob belongs to a
NonMusicalPaperColumn.stencil(unknown):ly:bar-line::printThe symbol to print.
bar-size(dimension, in staff space):ly:bar-line::calc-bar-sizeThe size of a 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:

thin-kern(number):3.0The space after a hair-line in a bar line.
hair-thickness(number):1.9Thickness of the thin line in a bar line.
thick-thickness(number):6.0Bar line thickness, measured in
line-thickness.
This object supports the following interfaces:
item-interface, font-interface, break-aligned-interface, bar-line-interface and grob-interface
