Ruby symbol and attribute -

when i'm creating attributes, can use symbols this:

class someclass   attr_reader :variable1, :variable2 end  

when i'm using keyword attr_reader (or attr_writer) , use same name instance variable, ruby automatically associate attribute (or say, property) instance variable same name?

you need understand attr_reader does. when do:

attr_reader :variable1, :variable2 

it gets translated into:

def variable1   @variable1 end def variable2   @variable2 end 

as can see variable1 instance variable @variable1 value setting within initialize method.

so yes, ruby associate attribute instance variable same name.
