In fact we can do this with quite little effort:
%%%%%
#(define (outside-staff-collecting-engraver context)
(let* ((span_up #f) (span_down #f))
(make-engraver
((initialize engraver)
(set! span_up (ly:engraver-make-grob engraver 'TextSpanner '()))
(ly:grob-set-property! span_up 'transparent #t)
(ly:grob-set-property! span_up 'direction UP)
(set! span_down (ly:engraver-make-grob engraver 'TextSpanner '()))
(ly:grob-set-property! span_down 'transparent #t)
(ly:grob-set-property! span_down 'direction DOWN))
(acknowledgers
((outside-staff-interface engraver grob source-engraver)
(display grob)
(if (assoc-get 'align (ly:grob-property grob 'details))
(let* ((d (ly:grob-property grob 'direction))
(span (if (= d UP) span_up span_down)))
(ly:grob-set-parent! grob Y span)
(if (null? (ly:spanner-bound span LEFT))
(ly:spanner-set-bound! span LEFT grob))
(ly:spanner-set-bound! span RIGHT grob)
(ly:grob-set-property! grob 'outside-staff-priority #f)
(ly:grob-set-property! grob 'Y-offset 0))))))))
\layout {
\context {
\Staff
\consists #outside-staff-collecting-engraver
}
}
\relative c'' {
\override TextScript.details.align = ##t
c_"I"^"a" c'_"II"^^ c,,_"III"^+ c'_"IV"^"d"\break
g_"A"^"e" g'_"B"^"f" g,,_"C"^"g" g'_"D"^"h"
}
\relative c'' {
\override TextScript.details.align = ##t
\override Script.details.align = ##t
c_"I"^"a" c'_"II"^^ c,,_"III"^+ c'_"IV"^"d"\break
g_"A"^"e" g'_"B"^"f" g,,_"C"^"g" g'_"D"^"h"
}
%%%%%
This will create an invisible TextSpanner above and below the staff and set Y
parent of oos grobs with details.align set to #t to the spanner corresponding
with it’s direction.
