Hi Michael,
Maybe something like this?
\version "2.21.80"
\layout {
indent = 5
}
#(define-markup-command (unit-height layout props arg) (markup?)
(let* ((stil (interpret-markup layout props arg))
(x (ly:stencil-extent stil 0)))
(interpret-markup layout props
(make-with-dimensions-markup x '(-0.5 . 0.5)
(markup #:general-align 1 0 arg)))))
Of course that's insane, because the same markup is interpreted twice,
and because 0.5 isn't an exact number. Hopefully better version:
\version "2.21.80"
\layout {
indent = 5
}
#(define-markup-command (force-unit-height layout props arg) (markup?)
(let* ((y-centered-arg (markup #:general-align 1 0 arg))
(stil (interpret-markup layout props y-centered-arg))
(x (ly:stencil-extent stil 0))
(y (cons -1/2 1/2)))
(ly:stencil-outline stil (make-filled-box-stencil x y))))
#(define-markup-command (unit-height-column layout props args)
(markup-list?)
(interpret-markup layout props #{
\markup {
\override #'(baseline-skip . 0)
\center-column \force-unit-height #args
} #} ))
\new Staff \with {
\override StaffSymbol.line-count = 12
instrumentName = \markup {
\override #'(font-size . -10)
\unit-height-column { First second third fourth fifth sixth seventh
eighth ninth tenth eleventh }
}
}
{ a'4 }
