Something like
#(define (moment->string mom)
(if (zero? (ly:moment-grace mom))
(number->string (ly:moment-main mom))
(format "~sG~a" (ly:moment-main mom) (ly:moment-grace mom))))
currentmom =
-\tweak text
#(lambda (grob)
(let* ((loc (grob::rhythmic-location grob)))
(if (pair? loc)
#{ \markup \with-color #red #(format "~a@~a" (car loc)
(moment->string (cdr loc))) #}
"")))
-""
{ c d\currentmom f g }
I would have used rhythmic-location->string but it relies on
ly:moment->string that never ever was defined over the history of
LilyPond. Cough cough.
