Don't forget you can store all the formatting as a music-function:
timestamp =
#(define-music-function (parser location minutes seconds) (number?
number?)
(let ((min (number->string minutes)) (sec (number->string
seconds)))
#{ \mark \markup \rounded-box \small \concat { $min ′ $sec
″ } #}))
{ c'1 \timestamp #4 #33 c' }
And solely out of paranoia, here's a version that doesn't rely on
the special utf-8 characters -- in case my prime and double-prime
characters above get corrupted on the way to your mailbox/browser:
timestamp =
#(define-music-function (parser location minutes seconds) (number?
number?)
(let ((min (number->string minutes)) (sec (number->string
seconds)))
#{ \mark \markup \rounded-box \small \concat
{ $min \char ##x2032 $sec \char ##x2033 } #}))
{ c'1 \timestamp #4 #33 c' }
