Hi,

Does anyone know how to create a ruby class in runtime?

ex:
class Parent
   def...
   def...
end

in runtime, we want to create a class "child" inherited from "parent",
it is possible?

thanks you very much

Yup, it is:

child = Class.new(parent) do
   def method(arg)
     ...
   end

   define_method(dynamic_name) do |arg|
     ...
   end

   # There's a gotcha, though:
   # Constant = 5 doesn't work as expected. Use this instead:
   const_set(:Constant, 5)
end
