Re: Setting font-features globally?

Hello John,

you can do this by setting this in the default props:

\paper {
    #(define fonts
        (set-global-fonts
            #:roman      "Linux Libertine"
            #:factor (/ staff-height pt 20)
        ))
    text-font-defaults = #(assoc-set! text-font-defaults 'font-features
'("smcp"))

assoc-set! here is a bad idea imho because it will mutate the original. You can see this in

\version "2.24.1"

\paper {
    text-font-defaults = #(assoc-set! text-font-defaults 'font-features '("smcp"))
    #(define fonts
        (set-global-fonts
            #:roman      "Linux Libertine"
            #:factor (/ staff-height pt 20)
        ))
}

\bookpart {
  \markup "abc" % no small caps because of bleedover from next \bookpart
}

\bookpart {
  \paper {
    text-font-defaults = #(assoc-set! text-font-defaults 'font-features #f)
 }
  \markup "abc"
}

You could use (assoc-set! (alist-copy text-font-defaults) ...), but LilyPond's nested assignment syntax text-font-defaults.font-features = ... is just as convenient (as in my first reply shortly before yours).
