Does a function like pythons dir() excist for ruby ?

[Asbjørn Reglund Thorsen]

I am using interactive Ruby for quick testing my swigged c++ module. In
python i can write down the command dir(), and I will get what`s inside
the module. Is there a similar function for Ruby ?

$ ri instance_methods
------------------------------------------------ Module#instance_methods
mod.instance_methods(include_super=false) => array
------------------------------------------------------------------------
Returns an array containing the names of public instance methods in
the receiver. For a module, these are the public methods; for a
class, they are the instance (not singleton) methods. With no
argument, or with an argument that is +false+, the instance methods
in _mod_ are returned, otherwise the methods in _mod_ and _mod_'s
superclasses are returned.

module A
def method1() end
end
class B
def method2() end
end
class C < B
def method3() end
end

A.instance_methods #=> ["method1"]
B.instance_methods #=> ["method2"]
C.instance_methods #=> ["method3"]
C.instance_methods(true).length #=> 43

A.instance_methods #=> ["method1"]
B.instance_methods #=> ["method2"]
C.instance_methods #=> ["method3"]
C.instance_methods(true).length #=> 43
