2.3.6 Functions without arguments
In most cases a function without arguments should be written with a variable,
dolce = \markup{ \italic \bold dolce }
However, in rare cases it may be useful to create a music function without arguments,
displayBarNum =
#(define-music-function
(parser location)
()
(if (eq? #t (ly:get-option 'display-bar-numbers))
#{ \once \override Score.BarNumber.break-visibility = ##f #}
#{#}))
To actually display bar numbers where this function is called,
invoke lilypond with
lilypond -d display-bar-numbers FILENAME.ly
