A much cleaner way would be to change the format-metronome-markup function to
make the context argument optional. If it is not given, simply default to #f
for hide-note:
(define-public (format-metronome-markup text dur count . context)
(let* ((ctx (and (pair? context) (car context)))
(hide-note (and ctx (eq? #t (ly:context-property
ctx 'tempoHideNote))))
(note-mark (if (and (not hide-note) (ly:duration? dur))
...
I don't know how useful this might be in general, but since it's such an easy
feature (and I don't think it breaks anything), I prepared a patch:
http://codereview.appspot.com/7055
What do you think?
One can then simply call
\version "2.11.62"
\header{
piece = #(format-metronome-markup "Allegro" (ly:make-duration 2) 120)
}
\relative c' { c }
Cheers,
Reinhold
