Dear LilyPond experts,
I would like to draw a text spanner between two notes across a system
break, with the letter 'x' at either end of the spanner. When I try
to do this, the cloning process creates an extra letter at the end of
the first system and the beginning of the next. I need to remove
these, but I don't know how. I tried copying the after-line-break
expression from the difficult tweaks section of the manuals (and
substituting the desired bound-details property and value) but it
didn't have any effect when I tried to call it.
Here is a pared-down version of what I am trying to do:
\version "2.16"
\relative c'' {
\override TextSpanner #'(bound-details left text) = x
\override TextSpanner #'(bound-details right text) = x
c1 \startTextSpan \break
c \stopTextSpan
}
...and here is the modified scheme expression. I know nothing about
scheme, so maybe my attempt to alter this is ridiculous, but I
appreciate if anyone could look/help:
#(define (my-callback grob)
(let* (
;; have we been split?
(orig (ly:grob-original grob))
;; if yes, get the split pieces (our siblings)
(siblings (if (ly:grob? orig)
(ly:spanner-broken-into orig)
'())))
(if (and (>= (length siblings) 2)
(eq? (car (last-pair siblings)) grob))
(ly:grob-set-property! grob '(bound-details right text) 'x ))))
...\override TextSpanner #'after-line-breaking = #my-callback has no effect.
Thanks in advance,
Kevin
