LilyPond Internals Reference: 3.1.87 RepeatTie

### 3.1.87 RepeatTie

RepeatTie objects are created by: Repeat_tie_engraver.

Standard settings:

> `control-points` (list):

>   `ly:semi-tie::calc-control-points`

>   List of offsets (number pairs) that form control points for the tie, slur, or bracket shape. For Béziers, this should list the control points of a third-order Bézier curve.

> `details` (list):

>   `'((ratio . 0.333) (height-limit . 1.0))`

>   Alist of parameters for detailed grob behavior. More information on the allowed parameters for a grob can be found by looking at the top of the Internals Reference page for each interface having a `details` property.

> `direction` (direction):

>   `ly:tie::calc-direction`

>   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`.

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

>   `'(-0.5 . 0.5)`

>   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)`.

> `head-direction` (direction):

>   `1`

>   Are the note heads left or right in a semitie?

> `stencil` (stencil):

>   `ly:tie::print`

>   The symbol to print.

> `thickness` (number):

>   `1.0`

>   Line thickness, generally measured in `line-thickness`.

This object supports the following interface(s): grob-interface, item-interface and semi-tie-interface.
