LilyPond Internals Reference: 3.1.23 BreathingSign

### 3.1.23 BreathingSign

BreathingSign objects are created by: Breathing_sign_engraver.

Standard settings:

> `break-align-symbol` (symbol):

>   `'breathing-sign`

>   This key is used for aligning and spacing breakable items.

> `break-visibility` (vector):

>   `#(#t #t #f)`

>   A vector of 3 booleans, `#(end-of-line unbroken begin-of-line)`. `#t` means visible, `#f` means killed.

> `non-musical` (boolean):

>   `#t`

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

> `space-alist` (list):

>   `'((ambitus extra-space . 2.0) (custos minimum-space . 1.0) (key-signature minimum-space . 1.5) (time-signature minimum-space . 1.5) (staff-bar minimum-space . 1.5) (clef minimum-space . 2.0) (cue-clef minimum-space . 2.0) (cue-end-clef minimum-space . 2.0) (first-note fixed-space . 1.0) (right-edge extra-space . 0.1))`

>   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`.

> `stencil` (stencil):

>   `ly:text-interface::print`

>   The symbol to print.

> `text` (markup):

>   `'(#<procedure musicglyph-markup (layout props glyph-name)> scripts.rcomma)`

>   Text markup. See Formatting text.

> `Y-offset` (number):

>   `ly:breathing-sign::offset-callback`

>   The vertical amount that this object is moved relative to its Y-parent.

This object supports the following interface(s): break-aligned-interface, breathing-sign-interface, font-interface, grob-interface, item-interface and text-interface.
