Since none of this works properly (I suspect it will require more than
Scheme hacking to get everything working), I don't think it's suitable
for inclusion.
Hm, I guess you're right - but as a compromise, how about letting the
\clearTabTieBreaks as a default, because it is working most of the time, and
when someone needs a more sophisticated tab staff, he has to write a
separate
score for the tablature?
I would propose to rename it as
#(define (tie::handle-tied-fret-numbers grob)
(let* ((tied-fret-nr (ly:spanner-bound grob RIGHT)))
(ly:grob-set-property! tied-fret-nr 'transparent #t)))
make it default by
\override Tie #'after-line-breaking = #tie::handle-tied-fret-numbers
and use this as a kind of starting point for future improvements?
Marc,
Have you explored the possibility of calling parentheses-item::print on your
tied fret number?
I don't know if it will work, but it appears it may be possible. It may
need to be defined public in order to call it.
It's found in scm/output-lib.scm.
