Thanks Leo, very interesting!
I report here, for other users, your same example adding the
command displayLilyMusic at the end.
When compiled, lilypond outputs (in the standard output) the resulting
music expression. For example for the following code:
\version "2.25.4"
%%%%%%%%%%%%%%%%%%
convertToSkips =
#(define-music-function (music) (ly:music?)
(music-map
(lambda (m)
(if (or (music-is-of-type? m 'rest-event)
(music-is-of-type? m 'note-event))
(make-music 'SkipEvent m)
m))
music))
%%%%%%%%%%%%%%%%%%
music = { r2\p <e' d'> c'4( d')\ff s4 r4 }
music = { r2\p <e' d'> c'4( d')\ff s4 r4 }
\score {\music}
\displayLilyMusic \convertToSkips \music
this is lilypond output:
