Ruby: constant, module, hash -

i'm few months learning ruby, , right i'm trying build south korean/north korean/english dictionary type of thing. i'm feeding text file has words.

so far i've got:

module dictionary    dictionary = []  end  class file    include dictionary    def self.convert(file)     readlines(file).each |line|       south, north, meaning = line.split(',')       dictionary << { :south => south, :north => north, :meaning => meaning }     end   end  end  file.convert("dictionary.txt")  dictionary::dictionary.sort_by { |word| word[:north] }.each |word|   puts "#{word[:south]} #{word[:north]} in north korean. both mean #{word[:meaning]}" end 

my question is:

1) unnecessary me make separate module array? (i trying experiment mixing in modules , classes)

2) using constant array right move? guess thought process wanted array able accessed outside, honest don't know i'm doing.

thanks in advance.

since dictionary loaded file, it's better have class instead of module each file can parsed separate dictionary.

class dictionary   attr_reader :content    def initialize     @content = []   end    def self.load(path)     instance = new     file.open(path) |f|       f.each_line |line|         instance.content << %i(south, north, meaning).zip(line.split(','))       end     end     instance   end end 

besides, can see didn't patch file class because file not creating dictionaries, sorts of file manipulation.
