A.20 Context modification identifiers
=====================================
The following commands are defined for use as context modifications
within a ‘\layout’ or ‘\with’ block.
‘RemoveAllEmptyStaves’
Remove staves which are considered to be empty according to the
list of interfaces set by ‘keepAliveInterfaces’, including those in
the first system.
• Sets grob property ‘remove-empty’ in ‘*note
(lilypond-internals)VerticalAxisGroup::’ to ‘#t’.
• Sets grob property ‘remove-first’ in ‘*note
(lilypond-internals)VerticalAxisGroup::’ to ‘#t’.
‘RemoveEmptyStaves’
Remove staves which are considered to be empty according to the
list of interfaces set by ‘keepAliveInterfaces’.
• Sets grob property ‘remove-empty’ in ‘*note
(lilypond-internals)VerticalAxisGroup::’ to ‘#t’.
[IR:]
2.2.5 Axis_group_engraver
-------------------------
Group all objects created in this context in a ‘VerticalAxisGroup’
spanner.
Properties (read)
‘currentCommandColumn’ (graphical (layout) object)
Grob that is X-parent to all current breakable (clef, key
signature, etc.) items.
‘hasAxisGroup’ (boolean)
True if the current context is contained in an axis group.
‘keepAliveInterfaces’ (list)
A list of symbols, signifying grob interfaces that are worth
keeping a staff with ‘remove-empty’ set around for.
Properties (write)
‘hasAxisGroup’ (boolean)
True if the current context is contained in an axis group.
This engraver creates the following layout object(s):
*note VerticalAxisGroup::.
‘Axis_group_engraver’ is part of the following context(s): *note
ChordNames::, *note DrumStaff::, *note Dynamics::, *note FiguredBass::,
*note FretBoards::, *note GregorianTranscriptionStaff::, *note
KievanStaff::, *note Lyrics::, *note MensuralStaff::, *note NoteNames::,
*note OneStaff::, *note PetrucciStaff::, *note RhythmicStaff::, *note
Staff::, *note TabStaff:: and *note VaticanaStaff::.
[ly/engraver-init.ly in definition of Score]
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, and appear only once.
stanza-number-interface
)
So probably you likely want to add the rest-interface to that list of
interfaces, probably in Staff context.
