The simple task of "require" in Ruby

Question

I follow the “Why Poignant Guide to Ruby” to learn Ruby, and I have problems when he first introduces the “require” (?) Method in his tutorial.

Essentially, I am making a file called "wordlist.rb" that contains:

code_words = { 'starmonkeys' => 'Phil and Pete, those prickly chancellors of the New Reich', 'catapult' => 'chucky go-go', 'firebomb' => 'Heat-Assisted Living', 'Nigeria' => "Ny and Jerry Dry Cleaning (with Donuts)", 'Put the kabosh on' => 'Put the cable box on' } 

Then I have another ruby ​​script called "files.rb":

 require 'wordlist' #Get evil idea and swap in code words print "Enter your new idea: " idea = gets #real will have the key and code will have the value #Method followed by ! (like gsub!) are known as destructive methods code_words.each do |real, code| safe_idea = idea.gsub!( real,code ) end #Save the jibberish to a new file print "File encoded. Please enter a name for this idea: " idea_name = gets.strip File::open( "idea-" + idea_name + ".txt", "w") do |f| f 

When I try to run the Ruby script i get:

  files.rb: 9: undefined local variable or method `code_words' for main: Object (NameError)

Any idea how to make the “require” work correctly to refer to a list of words?

There is a problem with the local variable. You can look here - there is exactly the same problem with the solution.
