Maybe something like this (but something that actually works LOL):
%%% SNIPPET BEGINS
\version "2.25.11"
omitt =
#(define-scheme-function (groblist) (grob-list?)
(for-each
(lambda (gr)
#{ \omit gr #})
groblist))
\omitt #'(TimeSignature NoteHead)
%%% SNIPPET ENDS
This snippet “works”, in that it iterates through the list and correctly
outputs the grob name:
%%% SNIPPET BEGINS
omitt =
#(define-scheme-function (groblist) (list?)
(for-each
(lambda (gr)
(ly:message
(format #f "~y" gr)))
groblist))
\omitt #'(TimeSignature NoteHead)
%%% SNIPPET ENDS
I’m just not sure the precise incantation to make the first snippet Do The
Right Thing™.
Hope this helps!
Kieren.
