Accessing "timecode" of notes or bars

[Boris Lau]

Hi all,

I'm trying to provide id-values to noteheads or barlines for use with 
the SVG output so I can access them using JavaScript. In the archive I 
found the snipped below.

1. Is there a property that gives me a timecode-like value for a 
notehead with a bar and beat number of a note?

2. I also tried to assign a string id to a BarLine, but that doesn't 
appear in the svg. Is there a workaround for that?

Best, Boris

#(define (note-number grob)
(string-concatenate
 (list
  "NoteHead/"
  (number->string
    (ly:beam-score-count)))))
      (ly:event-property (ly:grob-property grob 'cause)'pitch))))))
      (number->string


\override NoteHead #'id = #note-number


\relative c' {
  c8 d e f
}
