Dynamically creating class in Ruby

Question

I have a class that should look something like this:

class Family_Type1
    @people = Array.new(3)
    @people[0] = Policeman.new(\'Peter\', 0)
    @people[1         


        

Answer 1

From what I understand, you need meta-programming. Here is a snippet of code for creating classes dynamically (on the fly) with initialize method that initializes instance variables-

class_name = 'foo'.capitalize
klass = Object.const_set(class_name,Class.new)

names = ['instance1', 'instance2'] # Array of instance vars

klass.class_eval do
  attr_accessor *names

  define_method(:initialize) do |*values|
    names.each_with_index do |name,i|
      instance_variable_set("@"+name, values[i])
    end
  end
  # more...
end

Hope you can tweak it to suit your requirements.
