Got a couple of minutes:

Person = Struct.new :name,:last_name,:call_name,:age

class PersonList
 attr_reader :persons

 def initialize file
   @persons = {}
   File.foreach(file) do |line|
	   name, *rest_of_data = line.chomp.split(",")
     @persons[name] = Person.new(name, *rest_of_data)
   end
 end
end

person_list = PersonList.new("data2.txt")
p person_list.persons["name"]

I tried with this file:

name,lastname,callname,age
name2,lastname2,callname2,age2


and got:

$ ruby persons.rb
#<struct Person name="name", last_name="lastname",
call_name="callname", age="age">


Jesus.
