Comment:
It is now supported with MacRuby. You can check with the nightlies.
However, please be aware that for notifications to work as expected, you
will have to call #framework at least once:
{{{
# /tmp/kvn.rb
framework 'Foundation'
class Notifier
attr_accessor :value
end
class Observer
def observeValueForKeyPath(path, ofObject:object, change:change,
context:context) puts change end
end
n = Notifier.new
n.addObserver(Observer.new, forKeyPath:'value', options:0, context:nil)
n.value = 42
n.setValue 42
}}}
{{{
$> macruby /tmp/kvn.rb
{"kind"=>1}
{"kind"=>1}
$>
}}}
