Dynamic Class Definition WITH a Class Name

Question

How do I dynamically define a class in Ruby WITH a name?

I know how to create a class dynamically without a name using something li

Answer 1

The name of a class is simply the name of the first constant that refers to it.

I.e. if I do myclass = Class.new and then MyClass = myclass, the name of the class will become MyClass. However I can't do MyClass = if I don't know the name of the class until runtime.

So instead you can use Module#const_set, which dynamically sets the value of a const. Example:

dynamic_name = "ClassName"
Object.const_set(dynamic_name, Class.new { def method1() 42 end })
ClassName.new.method1 #=> 42
