How to read from a file & store key:value pair in String Array?

Question

I have a coffee script file with the following data in it. I want to create a string array that will store the following data as key:value pair in it.

abTests:
    productRanking:
      version: 4
      groups: [
        ratio:
          default: 1
          us: 0.90
          me: 0.0
        value: "LessPopularityEPC"
      ,
        ratio:
          default: 0
          us: 0.1
        value: "CtrEpcJob"
      ,
        ratio:
          default: 0
          me: 1.0
        value: "RandomPerVisitor"
      ]
    sabt:
      version: 1
      groups: [
        ratio:
          default: 1
          us: 0.90
        value: "default"
      ,
        ratio:
          default: 0
          us: 0.05
        value: "colorBoost"
      ,
        ratio:
          default: 0
          us: 0.05
        value: "colorPriority"
      ,
        ratio:
          default: 0
          us: 0
        value: "noColorClause"
      ]

I want to create a String Array with these data in the following format

productRanking:LessPopularityEPC
productRanking:CtrEpcJob
productRanking:RandomPerVisitor
sabt:default
sabt:colorboost
sabt:colorPriority
sabt:nocolorClause

Is there any way to solve this problem??

Instead of trying to parse CoffeeScript in Ruby, why don't you do it in CoffeeScript? Or in Node.js with one of the CSON modules? — Jordan Running

@Jordan I have to generate all possible combinations of key:value pair in order to automate these tests. I need to get the solution in Ruby only. Thanks for your input. — Chints Vadgama

Why do you need a Ruby-only solution? If you're working in Rails then you almost certainly have access to a JavaScript interpreter so why not use it? Correctly parsing CSON is probably harder than you think. — mu is too short

If by String Array you mean this

['productRanking:LessPopularityEPC', 'productRanking:CtrEpcJob', 'productRanking:RandomPerVisitor']

You can do that with the following coffeescript code

data = abTests:
  ...

array = []
for testName,tests of data['abTests']
  for categoryName,categoryElems of tests['groups']
    array.push (testName + ':' + categoryElems['value'])

console.log array
#=> ['productRanking:LessPopularityEPC', 'productRanking:CtrEpcJob', 'productRanking:RandomPerVisitor']

Thank you for your solution. Appreciate it. But, I have multiple keys like that. I meant to say my data further scales like this

productRanking:LessPopularityEPC productRanking:CtrEpcJob productRanking:RandomPerVisitor sabt:helloworld sabt:goworld mouseenter:true mouseenter:false

Is there any way that will fetch the key ?

I have added further data from the file & the solution that I required. It would be great if you could help me with that
