Ruby dynamic variable name

Question

is there any way to create variables in Ruby with dynamic names?

I'm reading a file and when I find a string, generates a hash.

e.g.

file = File.new("games.log", "r")  file.lines do |l|   l.split do |p|     if p[1] == "InitGame"       Game_# = Hash.new     end   end end 

How could I change # in Game_# to numbers (Game_1, Game_2, ...)

You can do it with instance variables like

i = 0 file.lines do |l|   l.split do |p|     if p[1] == "InitGame"       instance_variable_set("@Game_#{i += 1}", Hash.new)     end   end end 

but you should use an array as viraptor says. Since you seem to have just a new hash as the value, it can be simply

i = 0 file.lines do |l|   l.split do |p|     if p[1] == "InitGame"       i += 1     end   end end Games = Array.new(i){{}} Games[0] # => {} Games[1] # => {} ...
