The whole reason for exchanging the stencil seems to be getting sort
of superscript of "va" in "8va" and to have the spanning line starting
at top right edge.
If so, consider the code below.
Not that nice to mess around with \with-dimensions, but
`details.stencil-align-dir-y' had to be found manually before as well.
\version "2.19.32"
#(define eightva
#{
\markup
%% messing around with \with-dimensions, because OttavaBracket has no
%% possibility to set details.stencil-align-dir-y
%% :((
\with-dimensions #'(0 . 4) #'(0 . 2.8)
\italic \concat { "8" \raise #0.5 { \hspace #0.25 "va" } \hspace #0.5 }
#})
ottavaBracketNewText =
%% Not sure why a direct 'text-override does not work
\override Staff.OttavaBracket.after-line-breaking =
#(lambda (grob) (ly:grob-set-property! grob 'text eightva))
%% 1
{
\ottava #1
c''''1^"untouched original"
}
%% 2
{
\once \override Staff.OttavaBracket.shorten-pair = #'(-10 . -10)
\ottava #1
c''''1^"original, 'shorten-pair applied"
}
%% 3
{
\ottavaBracketNewText
\ottava #1
c''''1^"text changed"
}
%% 4
{
\once \override Staff.OttavaBracket.shorten-pair = #'(-10 . -10)
\ottavaBracketNewText
\ottava #1
c''''1^"text changed, 'shorten-pair applied"
}
HTH,
Harm
