Hi Harm,
Thanks for taking a look at it and for the tip on using a $-sign for 2.14.2. I
was also thinking about the best way to correct the 'stem-attachment values.
It would be nice if that could be automatic.
I had emailed David Nalesnik to ask about posting his code to the LSR, and he
also had the concern about the hard-coded 1.251178. He sent me the following
which automatically calculates the offset amount based on the width of the
NoteHead, so I will update the snippet with this revision.
#(define ((shift offsets) grob)
(let* ((note-heads (ly:grob-array->list (ly:grob-object grob 'note-heads)))
(stem (ly:grob-object grob 'stem))
(stem-ext (ly:grob-property stem 'X-extent)))
(for-each
(lambda (p q)
(let ((head-ext (interval-length (ly:grob-property p 'X-extent))))
(ly:grob-translate-axis! p (* q (- head-ext (cdr stem-ext))) X)))
note-heads offsets)))
displaceHeads =
#(define-music-function (parser location offsets) (list?)
#{
\once \override NoteColumn #'before-line-breaking = #(shift offsets)
#}
)
Regards,
-Paul
