Dear lilypond users,
I am trying to make a lilypond command for Roman numerals with a length
property that I can override. I have no idea what I'm doing when it comes
to scheme, and I can't seem to get a column to work properly. The function
I am trying to write is below. The problem is that the second #:line is
placed outside the column after it, instead of within it. My various
attempts to force it into the column all meet with errors. I tried using
the make-column-markup function as well to no avail. I can do it correctly
using ordinary markup commands, but then I can't seem to introduce the
property I want to be able to modify without causing errors. Any help would
be appreciated.
Kevin
#(define-markup-command (extender layout props) ()
#:properties ((xLength 4))
(interpret-markup layout props
(markup #:concat
("V" #:super #:column (#:line (#:number #:fontsize -2 "6"
#:raise 0.5 #:draw-line (cons xLength 0)
#:number #:fontsize -2 "5"))
(#:line (#:number #:fontsize -2 "4"
#:raise 0.5 #:draw-line (cons xLength 0)
#:number #:fontsize -2 "3"))))))
\relative c' {
c1_\markup { \extender }
}
