How can I create a ruby class in runtime

[sayoyo]

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_setConstant, 5)
end
