Hi Pierre & David, These solutions are quite amazing, and I've been able to make both work perfectly for what I want.
I'll document my understanding below for later readers of thread trying to finesse results. First I had to go read about the \shape command from David's solution ... http://lilypond.org/doc/v2.19/Documentation/notation/modifying-shapes#index-_005cshape ... which is easier to use than I would've imagined. The four pairs in ... \shape #'((-1.5 . 0) (-1 . 0) (-0.5 . 0) (0 . 0)) RepeatTie ... set the four control points that govern, er, shape the repeat-tie. And changing just the negative size of the leftmost value ... \shape #'((-2.5 . 0) (-1 . 0) (-0.5 . 0) (0 . 0)) RepeatTie ... gives exact control over the graphic length of the repeat. Then I digested Pierre's successive refinements to his repeatTieExtend function ... repeatTieExtend = #(define-music-function (parser location arg-repeat-tie-extend) (number?) #{ -\tweak X-extent #(cons (/ (+ arg-repeat-tie-extend 4) -1) 0) -\tweak details.note-head-gap #(/ arg-repeat-tie-extend -1) -\tweak extra-offset #(cons (/ arg-repeat-tie-extend -1) 0) -\tweak head-direction #1 \laissezVibrer #}) ... which made me realize that everything I'm wanting to do can be controlled by overrides to the RepeatTie (or, equivalently, LaissezVibrer) grob. After some experimentation, I found that just these three overrides ... \override RepeatTie.details.note-head-gap = -0.5 \override RepeatTie.extra-offset = #'(-0.5 . 0) \override RepeatTie.X-extent = ##f ... do exactly what I want. (Turning off X-extent makes repeat-ties work nicely with complex rhythms and proportional spacing.) Equivalently, these two overrides ... \shape #'((-1.5 . 0) (-1 . 0) (-0.5 . 0) (0 . 0)) RepeatTie \override RepeatTie.X-extent = ##f ... also do exactly what I want. (These settings are now inserted in a global stylesheet for the score.) The only mystery in any of these settings are the negative values ... \override RepeatTie.details.note-head-gap = -0.5 \override RepeatTie.extra-offset = #'(-0.5 . 0) ... which don't function exactly the way you might expect when you start changing them from, say, -0.25 to -0.5 to -1.5 to -2.5 and so on. But, happily, the values of -0.25 and -0.5 work very well. Thank you both very much. Both solutions give me what I was looking for and are producing beautiful output. Trevor.
