Re: Barres and enclose-bounds

[paulxiii]

Thanks. I changed the version number a few times until I got some meaningful
output from convert-ly. It couldn't do the whole job, but it gave an
indication as to what needed to be changed. I've ended up with the
following, which may be of help to others:

barre = #(define-music-function (parser location str)(string?)
    #{
       \once \override Voice . TextSpanner #'direction = #1
       \once \override Voice . TextSpanner #'style = #'line
       \once \override Voice . TextSpanner #'(bound-details right text) =
\markup { \draw-line #'(0 . -0.5) }
       \once \override Voice . TextSpanner #'(bound-details left text) =
#(markup (format "c~a" $str))
    #})

This works.

<< { <e''-4>4 <dis''-4> <cis''-4> | } \\                                        
     \override StringNumber #'extra-offset = #'(0.0 . -2.5)
     \once \override Voice.TextSpanner #'padding = #'5.5
   { \barre #"IX" <cis'-3\4>8\startTextSpan <e'-1\3> <b-1\4> e'\stopTextSpan
     \once \override Voice.TextSpanner #'padding = #'4.0
     \barre #"VII" <a-1\4>\startTextSpan <fis'-1\2>\stopTextSpan | } >>

My next exercise will be to see if I can adjust the width of the barre, as I
would like it to span to the outside edge of the note head, and not the
centre line, but I'll try figure that out before asking the question here.

P.S. I seem to have a different username now. Oh well. Getting the hang of
things.
