No idea why Frescobaldi complains about ly:Prob-property, i.e. with
upcase "P", afaict, it's not in the code...
Anyway, there were some internal changes in the relationship of
MultiMeasureRest and MultiMeasureRestNumber.
convert-ly can't be expected to cope with them.
Here a fixed version:
\version "2.22.0"
\layout {
\override Score.BarNumber.break-visibility = ##(#t #t #t)
}
fancyMultiMeasureRestNumber = {
\applyOutput Voice.MultiMeasureRestNumber
#(lambda (g c p)
(let* ((currentBarNumber (ly:context-property c 'currentBarNumber))
(mmr (ly:grob-parent g X))
(mmr-length
(ly:moment-main
(ly:prob-property (ly:grob-property mmr 'cause) 'length))))
(ly:grob-set-property! g 'text
#{
\markup
\center-column {
#(number->string mmr-length)
%% value found by try and error
\translate #'(0 . -7.5)
\with-dimensions #empty-interval #empty-interval
\halign #CENTER
\line
#(list (number->string currentBarNumber)
" - "
(number->string (1- (+ currentBarNumber mmr-length))))
}
#})))
\compressEmptyMeasures
}
{
c'1
\fancyMultiMeasureRestNumber R1*14
c'1
}
Cheers,
