Hey all,
I am working on a piece now where I need certain events to transmogrify into
other events. Specifically, whole-measure rests need to turn into
multi-measure rests, and given the way that the piece is algorithmically
generated, it would take a lot of time for me to change all of the `r' to `R'
when this is the case. I'd like to add a bit to rest-engraver.cc in the spirit
of :
if (to_boolean (get_property ("lazyMultiMeasureRests"))
&& (unsmob_moment (get_property ("measurePosition"))->main_part_ ==
Rational(0,0))
&& (unsmob_moment (get_property ("measureLength"))->main_part_ ==
unsmob_moment (rest_event_->get_property ("length"))->main_part_))
{
Stream_event *mmrest_event_ = new Stream_event (ly_symbol2scm
("multi-measure-rest-event"));
mmrest_event_->set_property ("duration", rest_event_->get_property
("duration"));
mmrest_event_->set_property ("length", rest_event_->get_property
("length"));
mmrest_event_->set_property ("duration-log", rest_event_->get_property
("duration-log"));
mmrest_event_->unprotect ();
context ()->event_source ()->broadcast (mmrest_event_);
return;
}
However, when I do this, it does not seem that the multi-measure-rest-engraver
hears the broadcast info.
I'm guessing this has something to do with how/when/where events are broadcasts
in the grand scheme of things, but I'm not sure. I see things called iterators
in the source that may be valuable for this type of hack, but I have no clue
how they work. Any ideas on how to accomplish this sorta thing?
Cheers,
MS
