LilyPond program-reference: 3.1.114 TimeSignature

### 3.1.114 TimeSignature

TimeSignature objects are created by: Time_signature_engraver.

Standard settings:

> `stencil` (unknown):

>   `ly:time-signature::print`

>   The symbol to print.

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

>   `'time-signature`

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

> `break-align-anchor` (number):

>   `ly:break-aligned-interface::calc-extent-aligned-anchor`

>   Grobs aligned to this break-align grob will have their X-offsets shifted by this number. In bar lines, for example, this is used to position grobs relative to the (visual) center of the bar line.

> `break-visibility` (vector):

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

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

> `avoid-slur` (symbol):

>   `'inside`

>   Method of handling slur collisions. Choices are `around`, `inside`, `outside`. If unset, scripts and slurs ignore each other. `around` only moves the script if there is a collision; `outside` always moves the script.

> `extra-spacing-height` (pair of numbers):

>   `'(-1.0 . 1.0)`

>   In the horizontal spacing problem, we increase the height of each item by this amount (by adding the ‘car’ to the bottom of the item and adding the ‘cdr’ to the top of the item). In order to make a grob infinitely high (to prevent the horizontal spacing problem from placing any other grobs above or below this grob), set this to `(-inf.0 . +inf.0)`.

> `space-alist` (list):

>   `'((first-note fixed-space . 2.0) (right-edge extra-space . 0.5) (staff-bar minimum-space . 2.0))`

>   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`.

> `non-musical` (boolean):

>   `#t`

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

> `style` (symbol):

>   `'C`

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

This object supports the following interface(s): time-signature-interface, item-interface, font-interface, break-aligned-interface and grob-interface.
