Sorry. I just explained all in the previous post, in reply to Aaron. Wrong topic/question. I think now all is clear. Best, Paolo

Thank you Aaron. I used a misleading topic, sorry. I wanted a set of layout
properties which is shared by all the scores I edit. So I can simply import
it with \include.
I thought that it was necessary to replicate these props in all the layout
blocks of all the scores. Then I asked for a "Scheme solution"
But this is not true:
%%%
\version "2.19.45"
\layout {
\context {
\Staff
\override StaffSymbol.color = #red
}
}
\layout {
\context {
\Staff
\override StaffSymbol.line-count = 3
}
}
<< \new Staff { b'4 } \new Staff { b'4 } >>
%%%
Re: Override a StaffSymbol property outside \new Staff { ... } context
Hi Paolo,
it seems like you have some very specific setup of lilypond files and
framework and need a solution that works within that, but you’re trying
to avoid explaining the whole setup either because it’s too much effort
or for privacy or similar. From my experience, when I get into that kind
of situation I have usually ended up in some kind of ‘rabbit hole’ and
the problem would be easier solved with a different setup in the first
place.
Can you describe the reason why you need this?
Best, Simon

To my knowledge, there is nothing more "global" than the top-level
\layout. (The same goes for \header, \paper, and \midi.)
If you are insistent on using Scheme, I believe the following is
functionally equivalent:
\version "2.19.83"
% LilyPond:
% \layout { \context { \Staff \override StaffSymbol.color = #red } }
% Scheme:
#(ly:output-def-set-variable! $defaultlayout 'Staff
(ly:context-def-modify
(ly:output-def-lookup $defaultlayout 'Staff)
#{ \with { \override StaffSymbol.color = #red } #}))
<< \new Staff { b'4 } \new Staff { b'4 } >>
Note that I still use LilyPond syntax to define the context-mod (i.e.
\with block), but even that could be completely done in Scheme:
\version "2.19.83"
#(ly:output-def-set-variable! $defaultlayout 'Staff
(ly:context-def-modify
(ly:output-def-lookup $defaultlayout 'Staff)
; LilyPond:
; #{ \with { \override StaffSymbol.color = #red } #}
; Scheme:
(ly:make-context-mod
`((assign StaffSymbol ,(ly:make-grob-properties
`((color . ,red
<< \new Staff { b'4 } \new Staff { b'4 } >>
However, why jump through such Scheme hoops when LilyPond syntax is more
direct?

Sorry Aaron, I was not precise in my question.
I need to override a property of StaffSymbol, for every staff, outside any
music expression/block context. Probably I'm not using the right words even
now.
But what I need is a sort of a "global" variable which is set for any staff
without having to put it into some music expression (like \layout {\context
{...}} , or \new Staff \with { ... } etc.).
This is why I asked if is there a Scheme solution

I would like to obtain something like:

Without needing to mess with Scheme, you can do this using the \layout
block providing you want to change all staves:
\version "2.19.83"
\layout {
\context {
\Staff
\override StaffSymbol.color = #red
}
}
\new Staff { b'4 }
\new Staff { b'4 }
\new Staff { b'4 }
(That is a top-level \layout block, but the same can be done within a
\score to scope the effect.)
If you only need to affect specific staves but want to avoid duplicating
the overrides, put them in a variable to reference as needed:
\version "2.19.83"
redLines = \with { \override StaffSymbol.color = #red }
\new Staff { b'4 }
\new Staff \with { \redLines } { b'4 }
\new Staff \with { \redLines } { b'4 }
Lastly, you could even define your own Staff-like context and embed the
property changes within it:
\version "2.19.83"
\layout {
\context {
\Staff
\type Engraver_group
\name RedStaff
\alias Staff
\override StaffSymbol.color = #red
}
\inherit-acceptability RedStaff Staff
}
\new Staff { b'4 }
\new RedStaff { b'4 }
\new RedStaff { b'4 }
