I sent the following to Jaime E Oliver so I wanted to post it here also.
It's my code for special glissandi.
It's still personal code so naturally it can't be guaranteed to work for all use cases; all I can is that it works well for my needs.
With a view to making these functions more effecient I was wondering if the fact that I've used a lot of embedded postscript code is a bad thing? Postscript has some nice functionality for looping and repeating drawing commands which is one of the reasons I was drawn to it.
The main thing to watch out for is that this code doesn't behave across line-breaks; I imagine this wouldn't be trivial to implement and so haven't been too concerned by it. It would be amazing to have this, especially if working on scores involving large groups of instruments.
I plan to have some down time in February/March when I can get around to tidying up some other code and putting it out there for those who might be interested.
all the best,
piaras
