Hello

I need to find a classe when I have its name in a string like this

module Tutu
class Toto
end
end

module Popo
class Pupu
def truc
toto_class=FIND(‘Tutu::Toto’)
toto=toto_class.new
end
end
end

Someone have an idea ?

Bye

your FIND is Module#const_get

irb(main):001:0> Object::const_get ‘Class’
=> Class
irb(main):002:0> class Mia; end
=> nil
irb(main):003:0> Object::const_get(‘Mia’).new
=> #Mia:0x27cb920

Ok thank but with old messages I make this method

module Introspection

class ClassNotFound < Exception ; end

class Find
def self.find_class(class_name)
ObjectSpace.each_object(Module) do |n|
if n.name==class_name then
return n
end
end
raise ClassNotFound
end
end

end
