Hi Urs, I've had good luck creating custom grob properties, which sounds like what you're looking for. Here's how I do it, with some example custom properties that I use: %% CUSTOM GROB PROPERTIES %% I use "cn-" to keep my functions separate from standard %% LilyPond functions (like a poor man's namespace). % function from "scm/define-grob-properties.scm" (modified) #(define (cn-define-grob-property symbol type?) (set-object-property! symbol 'backend-type? type?) (set-object-property! symbol 'backend-doc "custom grob property") symbol) #(cn-define-grob-property 'cn-is-clairnote-staff boolean?) #(cn-define-grob-property 'cn-vscale-staff number?) Once they are defined I can use the custom properties with any grob (e.g. StaffSymbol): \override StaffSymbol.cn-is-clairnote-staff = ##t \override StaffSymbol.cn-vscale-staff = #1.2 I suppose for an alist you would just use list? as the type predicate (or maybe there's one for alists?).
