Ruby Anomaly

Postby DaveyBoy » Wed Nov 13, 2019 12:42 am

Hi Guys

Just noticed the following Ruby anomaly:

Image

.to_a works for a range but not for midi
and
.to_array works for midi but not for a range.

Does anybody know why this is?

There is no #to_b in Ruby

Yes, because DSPR did a dirty work while programming the method.

Ruby knows two (and only two) array conversion methods: to_a (explicit conversion) and to_ary (implicit conversion).

When you create your own class, you are encouraged to hook into those. But DSPR ignored it and created a non-ruby-compatible method called to_array. Unfortunately it is confusing (as your post proves) and nothing we can change. We have to live with it, which triggers my perfection OCD. I'm sure, there are more of those language breaking lazy DSPR methods around.
