LilyPond Internals Reference: 3.1.121 SystemStartBar

### 3.1.121 SystemStartBar

SystemStartBar objects are created by: System_start_delimiter_engraver.

Standard settings:

> `collapse-height` (dimension, in staff space):

>   `5.0`

>   Minimum height of system start delimiter. If equal or smaller, the bracket/brace/line is removed.

> `direction` (direction):

>   `-1`

>   If `side-axis` is `0` (or `X`), then this property determines whether the object is placed `LEFT`, `CENTER` or `RIGHT` with respect to the other object. Otherwise, it determines whether the object is placed `UP`, `CENTER` or `DOWN`. Numerical values may also be used: `UP`=`1`, `DOWN`=`-1`, `LEFT`=`-1`, `RIGHT`=`1`, `CENTER`=`0`.

> `padding` (dimension, in staff space):

>   `-0.1`

>   Add this much extra space between objects that are next to each other.

> `stencil` (stencil):

>   `ly:system-start-delimiter::print`

>   The symbol to print.

> `style` (symbol):

>   `'bar-line`

>   This setting determines in what style a grob is typeset. Valid choices depend on the `stencil` callback reading this property.

> `thickness` (number):

>   `1.6`

>   For grobs made up of lines, this is the thickness of the line. For slurs and ties, this is the distance between the two arcs of the curve’s outline at its thickest point, not counting the diameter of the virtual “pen” that draws the arcs. This property is expressed as a multiple of the current staff-line thickness (i.e. the visual output is influenced by changes to `Staff.StaffSymbol.thickness`).

> `X-offset` (number):

>   `ly:side-position-interface::x-aligned-side`

>   The horizontal amount that this object is moved relative to its X-parent.

This object supports the following interface(s): grob-interface, side-position-interface, spanner-interface and system-start-delimiter-interface.
