Hi Ursus,
I have run the code through convert-ly, no changes were needed. I
compiled on an older pc with an older version of lilypond without
problems. So it seems there is some difference between 2.20.0 and
2.22.0 that breaks the code.
The markup command \note has changed: Now it expects a duration, not a
string anymore. But you can use the internal function \note-by-number
instead:
\version "2.22.0"
#(use-modules (srfi srfi-60))
#(define-public (format-time-sig-note grob)
(let* ((frac (ly:grob-property grob 'fraction))
(num (if (pair? frac) (car frac) 4))
(den (if (pair? frac) (cdr frac) 4))
(m (markup #:override '(baseline-skip . 0.5)
#:center-column (#:number (number->string num)
#:override '(style .
default)
#:note-by-number
(log2-binary-factors den) 0 DOWN))))
(grob-interpret-markup grob m)))
{
\override Staff.TimeSignature.stencil = #format-time-sig-note
\time 4/2
a4
}
Anyway, it seems to me that, even before that change, you had no
possibility of writing something like "4 dotted quarter notes". Do you
need that functionality?
