Get list of a class' instance methods

Question

I have a class:

class TestClass   def method1   end    def method2   end    def method3   end end 

How can I get a list of my methods in this class (method1, method2, method3)?

Answer 1

You actually want TestClass.instance_methods, unless you're interested in what TestClass itself can do.

class TestClass   def method1   end    def method2   end    def method3   end end  TestClass.methods.grep(/method1/) # => [] TestClass.instance_methods.grep(/method1/) # => ["method1"] TestClass.methods.grep(/new/) # => ["new"] 

Or you can call methods (not instance_methods) on the object:

test_object = TestClass.new test_object.methods.grep(/method1/) # => ["method1"]
