Re: context id

[Milan van der Meer]

the code (frescobaldi):

#(define (format-note engraver event)
  (let* (
          (context (ly:translator-context engraver))
          (ID (ly:context-id context))
          (parent (ly:context-parent context))
          (name (ly:context-name context) )


          )
    (display ID)

    (make-eventlist engraver event)
   )
 )



\layout {
  \context {
  \Score
  \consists #(make-engraver
              (listeners

         (note-event . format-note)

  ))

\new Staff <<
  \new Voice = "first"
    { \voiceOne a }
  \new Voice= "second"
    { \voiceTwo d }
>>
