LilyPond Internals Reference: 3.1.107 RepeatTie

### 3.1.107 `RepeatTie`

A repeat tie (i.e., a tie from nothing to a note). See also `RepeatTieColumn`, `LaissezVibrerTie`, and `Tie`.

`RepeatTie` objects are created by: `Repeat_tie_engraver`.

Standard settings:

`control-points` (list of number pairs):

  `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` (alist, with symbols as keys):

      '((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`

  For grobs made up of lines, this is the thickness of the line. For slurs and ties, this is the distance between the two arcs of the curve’s outline at its thickest point, not counting the diameter of the virtual “pen” that draws the arcs. This property is expressed as a multiple of the current staff-line thickness (i.e., the visual output is influenced by changes to `Staff.StaffSymbol.thickness`).

`vertical-skylines` (pair of skylines):

  `#<unpure-pure-container #<procedure ly:grob::vertical-skylines-from-stencil (_)> >`

  Two skylines, one above and one below this grob.

`Y-extent` (pair of numbers):

  `#<unpure-pure-container #<procedure ly:grob::stencil-height (_)> >`

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

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

This object is of class Item (characterized by `item-interface`).
