Re: Define Music Function

[ctesta]

Thanks for the help everyone. I am getting closer. I have one other
question. How could I set the font-size of the first number to be bigger
that the numbers of the fraction?

This currently works, but I need the first number to be font-size = #6 and
the numerator and denominator to be font-size = #3 or so.

fractionRest = #(define-music-function (parser location string num denom)
(string-or-symbol? string-or-symbol? string-or-symbol?)
  #{
    \once \override Staff.Rest #'font-size = #3
    \once \override Staff.Rest #'stencil = #ly:text-interface::print
    \once \override Staff.Rest #'text = #(markup #:musicglyph $string
#:column (#:musicglyph $num #:musicglyph $denom))
    \once \override Dots #'transparent = ##t
    #}
)

This doesn't work.

fractionRest = #(define-music-function (parser location string num denom)
(string-or-symbol? string-or-symbol? string-or-symbol?)
  #{
    \once \override Staff.Rest #'font-size = #3
    \once \override Staff.Rest #'stencil = #ly:text-interface::print
    \once \override Staff.Rest #'text = #(markup #'font-size = #6
#:musicglyph $string #:column (#'font-size = #3 #:musicglyph $num
#:musicglyph $denom))
    \once \override Dots #'transparent = ##t
    #}
)

How would I do this?

Thanks so much,
Carl
