Re: \unset with modified default properties
Sure, define-music-function works fine. That part I just copied from the
earlier snippet. That's a side issue, though.

Why not define-music-function? This seems like asking for trouble
unnecessarily.

Re: \unset with modified default properties
Indeed, or StaffGroup level if I'm following correctly. My issue is that I
want to change the default keepAliveInterfaces for one staff within a
StaffGroup. (Probably should have just posted this as my initial example, I
suppose.)
\version "2.19.82"
targetstaff = #(define-scheme-function (ctx) (string?)
#{
\set Staff.keepAliveInterfaces = #'()
\context Staff = #ctx { \unset Staff.keepAliveInterfaces }
#})
music = {
\targetstaff "2"
c'1 d' e' d'
\break
\targetstaff "1"
R1*4
}
\new StaffGroup <<
\new Staff = "1" \with {
\override VerticalAxisGroup.remove-empty = ##t
\override VerticalAxisGroup.remove-first = ##t
instrumentName = "1"
shortInstrumentName = "1"
} \music
\new Staff = "2" \with {
\override VerticalAxisGroup.remove-empty = ##t
\override VerticalAxisGroup.remove-first = ##f
instrumentName = "2"
shortInstrumentName = "2"
keepAliveInterfaces = #'(
bass-figure-interface
chord-name-interface
cluster-beacon-interface
fret-diagram-interface
lyric-syllable-interface
note-head-interface
tab-note-head-interface
lyric-interface
percent-repeat-item-interface
percent-repeat-interface
;; need this, as stanza numbers are items,

} \music

This is adapted from a snippet posted a while ago on the mailing list:

Does this clarify what I'm trying to do with \unset?
Thanks!

Re: \unset with modified default properties
Interesting. So if the default property is set at the Staff level, for
instance, then changed and \unset at the Voice level, it goes back to the
default for the higher-level context. But if in the example \new Staff
\with... is changed to \new Voice \with... the original problem arises
where \unset reverts to the built-in default.
Didn't realize about the \tuplet syntax. That's quite useful. Thanks for
the tip!
Actually, I just used tupletSpannerDuration because it was convenient to
write a tiny example. My practical use case is changing the default
keepAliveInterfaces for certain staves.

There are several approaches. The tupletSpannerDuration is actually
interpreted at Voice level, so if you set/unset the Voice level value,
it remains dominant while set and can be unset nicely:
music = \relative c' {
\tuplet 3/2 {
c8 c c d d d e e e f f f |
}
\set tupletSpannerDuration = #(ly:make-moment 1/2)
\tuplet 3/2 {
c8 c c d d d e e e f f f |
}
\unset tupletSpannerDuration
\tuplet 3/2 {
c8 c c d d d e e e f f f |
}
}
\new Staff \with {
tupletSpannerDuration = #(ly:make-moment 1/4)
} \music
But of course for this functionality in particular, use the optional
tuplet spanner duration argument to the \tuplet music function:
music = \relative c' {
\tuplet 3/2 {
c8 c c d d d e e e f f f |
}
\tuplet 3/2 2 {
c8 c c d d d e e e f f f |
}
\tuplet 3/2 {
c8 c c d d d e e e f f f |
}
}
\new Staff \with {
tupletSpannerDuration = #(ly:make-moment 1/4)
} \music
In fact, I'd lean towards using it always and not even bother setting
tupletSpannerDuration at all. So basically:
music = \relative c' {
\tuplet 3/2 4 {
c8 c c d d d e e e f f f |
}
\tuplet 3/2 2 {
c8 c c d d d e e e f f f |
}
\tuplet 3/2 4 {
c8 c c d d d e e e f f f |
}
}
\music
It's minimal writing effort and keeps the information where it belongs.

Re: \unset with modified default properties
Unfortunately, for my use case, \once\set and \once\unset aren't enough.

Is

While not a completely general solution, you may be able to use \once:
music = \relative c' {
\tuplet 3/2 {
c8 c c d d d e e e f f f |
}
\once \set Staff.tupletSpannerDuration = #(ly:make-moment 1/2)

\tuplet 3/2 {

\unset with modified default properties
In both 2.18 and 2.19, \unset appears to set a context property to the
built-in default, rather than the default set in the \with {} block:
music = \relative c' {
\tuplet 3/2 {
c8 c c d d d e e e f f f |
}
\set Staff.tupletSpannerDuration = #(ly:make-moment 1/2)
\tuplet 3/2 {
c8 c c d d d e e e f f f |
}
\unset Staff.tupletSpannerDuration
\tuplet 3/2 {
c8 c c d d d e e e f f f |
}
}
\new Staff \with {
tupletSpannerDuration = #(ly:make-moment 1/4)
} \music
In cases like this, I would find it useful to reset the property to the
custom default value without having to explicitly \set it every time. Is
there a way to do this? Also, is this the most useful behavior of \unset?
