Hi,2015-04-16 3:36 GMT+02:00 Trevor Bača <address@hidden>:Hi,Using the \shape command to length repeat ties works great between notes. But weird behavior seems to arise with lengthened repeat ties between chords:### BEGIN ###\version "2.19.17"\language "english"\new Staff \with {\shape #'((-2 . 0) (-1 . 0) (-0.5 . 0) (0 . 0)) RepeatTie\override RepeatTie.X-extent = ##f} {<c' g'>1<c' g'>1 \repeatTie<c' g'>1 \repeatTie<c' g'>1 \repeatTie}### END ###(Image attached.)Would anyone have any clues as to how to make the repeat ties all have the same length?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}%%%%%HTH,David
