Here's how you could add an argument for 'font-size to your function:
\version "2.18.2"
music = \relative c' {c2 d e f g a b c c b a g f e d c}
newnames =
#`(("c" . "S")
("d" . "R")
("e" . "G")
("f" . "M")
("g" . "P")
("a" . "D")
("b" . "N")
)
myNoteNames =
#(lambda (size)
(lambda (grob)
(let* (
;; bindings
(default-name (ly:grob-property grob 'text))
(new-name (assoc-get default-name newnames))
)
;; body
(ly:grob-set-property! grob 'text new-name)
(ly:grob-set-property! grob 'font-size size)
(ly:text-interface::print grob)
)
))
#(define (myNoteNames size)
(lambda (grob)
(let* (
;; bindings
(default-name (ly:grob-property grob 'text))
(new-name (assoc-get default-name newnames))
)
;; body
(ly:grob-set-property! grob 'text new-name)
(ly:grob-set-property! grob 'font-size size)
(ly:text-interface::print grob)
)
))
\new Staff {
<<
\new Voice {
\music
\shiftDurations #1 #0 {\music }
\shiftDurations #2 #0 {\music \music }
}
\context NoteNames {
\override NoteName.stencil = #(myNoteNames 1)
\music
\override NoteName.stencil = #(myNoteNames -2)
\shiftDurations #1 #0 {\music }
\override NoteName.stencil = #(myNoteNames -4)
\shiftDurations #2 #0 {\music \music }
}
>>
}
%%%%%%%%%%%%%%
Notice that I've given two versions of myNoteNames. They are equivalent.
(I find the second easier to use, but maybe that's just me.)
Now, if you want to have LilyPond detect the note durations and make the
fontsize decisions for you, I don't believe you'll be able to use the
NoteNames grob as it stands. It would be nice if a NoteNames object had a
pointer to a NoteHead, from which information like duration could be
gleaned, but it doesn't.
Hope this helps.
David
