Given the following code,
{{{
module Foo
module Baz
def initialize(a, b)
end
end
end
module Foo
module Bar
module Baz
include Foo::Baz
def initialize(a, b, c, d)
super(a, b)
end
end
end
end
module Foo
module Bar
module Quux
include Baz
end
end
end
module Foo
module Bar
module Baz
class Bat
include Foo::Bar::Baz
include Foo::Bar::Quux
end
end
end
end
}}}
There are two related errors associated with this piece of code.
1.
{{{Foo::Bar::Baz::Bat.new}}}
'''Expected result (Ruby 1.9.1)'''
ArgumentError: wrong number of arguments (0 for 4)
'''Actual result (MacRuby 0.5b2)'''
=> #<Foo::Bar::Baz::Bat:0x200252380>
Note the difference in response from #512!
2.
{{{Foo::Bar::Baz::Bat.new(nil, nil, nil, nil)}}}
'''Expected result (Ruby 1.9.1)'''
=> #<Foo::Bar::Baz::Bat:0x913598>
'''Actual result (MacRuby 0.5b2)'''
ArgumentError: wrong number of arguments (4 for 2)
It seems that MacRuby is becoming confused. Here are a few ways to make
it understand that Foo::Bar::Baz::Bat#initialize should accept 4
arguments.
- Comment out Foo::Bar::Baz::Bat's second include statement (line
33)[[BR]]
- Comment out Foo::Bar::Quux's include statement (line 23)[[BR]]
- Comment out Foo::Bar::Baz's include statement (line 11) and
Foo::Bar::Baz#initialize's super call (line 14)
Of course, for my application I need the original functionality, so none
of those will work for me. :-) If you find a workaround while
investigating, please let me know.
