LilyPond Internals Reference: 3.1.111 SystemStartBrace

### 3.1.111 SystemStartBrace

SystemStartBrace 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`.

> `font-encoding` (symbol):

>   `'fetaBraces`

>   The font encoding is the broadest category for selecting a font. Currently, only lilypond’s system fonts (Emmentaler) are using this property. Available values are `fetaMusic` (Emmentaler), `fetaBraces`, `fetaText` (Emmentaler).

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

>   `0.3`

>   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):

>   `'brace`

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

> `X-offset` (number):

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

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

> `Y-extent` (pair of numbers)

>   Hard coded extent in Y direction.

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