It avoids creating all those grobs and killing most of them in the
end. Instead a preexisting RehearsalMark (or more of them) is taken
and 'text is reset.
Some other changes for better usability.
Hi Harm, Nice work! I'd say this is a good candidate for the LSR,
particularly because it demonstrates listeners, acknowledgers, and
finalize in one engraver.
One little thing I noticed is that
(if duration-marks
should be something like
(if (not (null? duration-marks))
Because:
\version "2.19.42"
#(define empty-list '())
#(display (if empty-list #t #f))
% --> #t
#(display (if (not (null? empty-list)) #t #f))
% --> #f
Also, I wonder, where you clear out these variables at the end of the
finalize stage:
(set! evts '())
(set! last-evt #f)
(set! tempo-change-evts '())
(set! duration-marks '())
Of course, it doesn't hurt, but is it necessary? If so I need to do
that in my code.
