In order to use a shape-like command with repeat ties in a chord, we have
to get at the individual ties organized by the RepeatTieColumn.
Here's a variant of \shapeTieColumn (at
https://github.com/openlilylib/openlilylib/tree/master/notation-snippets/shaping-bezier-curves/shape-tie-column)
which achieves that. Each tie within the chord is represented with its own
list of offsets.
%%%%
\version "2.19.17"
\language "english"
shapeRepeatTieColumn =
#(define-music-function (parser location all-offsets) (list?)
#{
\override RepeatTieColumn #'before-line-breaking =
#(lambda (grob)
(let ((ties (ly:grob-array->list (ly:grob-object grob 'ties))))
(for-each
(lambda (tie offsets-for-tie)
(if (number-pair-list? offsets-for-tie)
(set! (ly:grob-property tie 'control-points)
(map
(lambda (x y) (coord-translate x y))
(ly:semi-tie::calc-control-points tie)
offsets-for-tie))))
ties all-offsets)))
#})
\new Staff \with {
\shapeRepeatTieColumn #'(
((-2 . 0) (-1 . 0) (-0.5 . 0) (0 . 0))
((-2 . 0) (-1 . 0) (-0.5 . 0) (0 . 0))
)
\override RepeatTie.X-extent = ##f
} {
<c' g'>1
<c' g'>1 \repeatTie
<c' g'>1 \repeatTie
<c' g'>1 \repeatTie
}
