Simple Ruby mad lib w/ external include (intro programming tips)

Ah ha, so here we’ll use server-side Ruby to create a “Mad Lib” type program where we’ll pass prompted user input to dynamic placeholders through an external .txt include file. Neato!

filename = "story.txt" 

puts "Enter a noun: "

puts "Enter a verb: "

puts "Enter an adjective: "

puts "Enter an adverb: "

if contents.include?('NOUN')
  { "\[NOUN\]" => noun,
    "\[VERB\]" => verb,
    "\[ADJ\]" => adj,
    "\[ADV\]" => adv
  }.each do |key, value|
    contents.gsub!(key, value)
  end, "w") { |f| f << contents }


Fyi, my /story.txt for this example, originally looks like this:

\n\nOnce upon a time on the internet...\n\n
	  At a very reluctant [NOUN] I would sometimes [VERB] while being [ADJ] and [ADV] very fast (in Canada).

So, the above ‘story’ will be populated with the user inputs; i.e. [NOUN] will have the user inputted ‘[NOUN]‘ and so on and so forth. We now have a little program that prompts the user to input ‘nouns’, ‘adjectives’, and ‘adverbs’ and then invokes the user input into our story.txt include ‘mad lib’ story.
