Colliding method names

ruby-talk

Hi,

If I'm running irb and I run a method called `foo`, is there a way to find out which foo was called? I'm getting some strange results and wonder if there's more than one method with the same name out there.

Any help is much appreciated.

Regards,
Iain

You can use #method

begin
  method :foo # =>
rescue
  $! # => #<NameError: undefined method `foo' for class `Object'>
end

def foo
end
method :foo # => #<Method: Object#foo>

def self.foo
end
method :foo # => #<Method: main.foo>

"hello world".instance_eval do

  method :foo # => #<Method: String(Object)#foo>

  class String
    def foo
    end
  end
  method :foo # => #<Method: String#foo>

  def self.foo
  end
  method :foo # => #<Method: "hello world".foo>

end
