### 3.1.22 BreakAlignment

BreakAlignment objects are created by: Break_align_engraver.

Standard settings:

> `axes` (list):

>   `'(0)`

>   List of axis numbers. In the case of alignment grobs, this should contain only one number.

> `break-align-orders` (vector):

>   `#((left-edge cue-end-clef ambitus breathing-sign clef cue-clef staff-bar key-cancellation key-signature time-signature custos) (left-edge cue-end-clef ambitus breathing-sign clef cue-clef staff-bar key-cancellation key-signature time-signature custos) (left-edge ambitus breathing-sign clef key-cancellation key-signature time-signature staff-bar cue-clef custos))`

>   Defines the order in which prefatory matter (clefs, key signatures) appears. The format is a vector of length 3, where each element is one order for end-of-line, middle of line, and start-of-line, respectively. An order is a list of symbols.

>   For example, clefs are put after key signatures by setting

> `non-musical` (boolean):

>   `#t`

>   True if the grob belongs to a `NonMusicalPaperColumn`.

> `stacking-dir` (direction):

>   `1`

>   Stack objects in which direction?

> `X-extent` (pair of numbers):

>   `ly:axis-group-interface::width`

>   Extent (size) in the X direction, measured in staff-space units, relative to object’s reference point.

This object supports the following interface(s): axis-group-interface, break-alignment-interface, grob-interface and item-interface.
