This is a spanner with an end 'hook' - I use it for telling in which cello
position a passage should be played:
\version "2.16.1"
% Allows to draw a dashed text spanner for highlighting sections with a
given playng position in a score
stringNumberSpanner =
#(define-music-function (parser location stringNumber) (string?)
#{
\override TextSpanner #'style = #'dashed-line
\override TextSpanner #'dash-period = #1.5
\override TextSpanner #'dash-fraction = #0.5
\override TextSpanner #'font-size = #-5
\override TextSpanner #'font-shape = #'upright
\override TextSpanner #'(bound-details left stencil-align-dir-y) =
#CENTER
\override TextSpanner #'(bound-details left text) = \markup { \number
$stringNumber }
% \override TextSpanner #'(bound-details right text) = \markup {
\draw-line #'(0 . -1) }
\override TextSpanner #'outside-staff-priority = 500
#}
)
Hope this helps.
Best regards,
Olivier
