For that particular problem, I use a function that transform a figured
bass expression, ie:
\figuremode { <_>4 <5> <4-> }
to a regular voice with skips and markups, ie (approximatively):
{ s4 s-\markup \number 5 s-\markup { \number 4 \flat } }
I still have problems with it, but here is a function which might
be a starting point:
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%% Custom figured bass
#(define (fig-seq->markup-seq seq-music)
;;
(define (alteration->markup alteration)
(make-raise-markup
(if (= alteration FLAT)
0.3
0.6)
(make-musicglyph-markup
(string-append "accidentals-" (number->string alteration)))))
;; BassFigureEvent --> TextScriptEvent and SkipEvent
(define (fig->markup fig-music)
(let* ((fig (ly:music-property fig-music 'figure))
(acc (ly:music-property fig-music 'alteration))
(acc-markup #f)
(fig-markup (if (markup? fig)
fig
(if (not (eq? acc '()))
(make-simple-markup "")
(make-strut-markup)))))
(list
(make-music 'TextScriptEvent
'direction -1
'text (markup #:teeny (if (number? acc)
(markup fig-markup
(alteration->markup acc))
fig-markup)))
(make-music 'SkipEvent
'duration (ly:music-property fig-music 'duration)))))
;;
(if (not (null? seq-music))
(begin
(if (ly:music-property seq-music 'element)
(set! (ly:music-property seq-music 'element)
(fig-seq->markup-seq (ly:music-property seq-music 'element))))
(set! (ly:music-property seq-music 'elements)
(let ((elements (list)))
(for-each (lambda (mus)
(if (eqv? (ly:music-property mus 'name) 'BassFigureEvent)
(set! elements (append (fig->markup mus) elements))
(set! elements (cons (fig-seq->markup-seq mus) elements))))
(ly:music-property seq-music 'elements))
(if (eqv? (ly:music-property seq-music 'name) 'EventChord)
elements
(reverse! elements))))))
seq-music)
markupfigures=#(def-music-function (location music) (ly:music?)
(fig-seq->markup-seq music))
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
It can be used like this:
\new Staff <<
\clef bass
\notemode { c2 d4 }
\markupfigures \figuremode { <_>4 <5> <4-> }
>>
