I was recently asked to write a fizzbuzz solution in a technical interview. To make this challenge more interesting, I wrote a little script that scrapes RosettaCode for Ruby solutions to FizzBuzz. This is nice, but not very useable. So, I packaged it as a gem that will take any query and any language to scrape RosettaCode for.
run gem install rosettacode from your terminal. also, add require 'rosetta' to your gemfile. Now you're ready to go - the gem is namespaced in a module called Lazy (because that's what I am), so you can use it by doing Lazy::Rosetta.search(query, language). If no language is given, it defaults to Ruby. For example, try the query of FizzBuzz - you will see the first solution printed out to the terminal, and a FizzBuzz.rb file is written that contains all the ruby solutions to FizzBuzz from RosettaCode. Another example - try the query of "Fibonacci_sequence" with the language of "javascript".
There is also a CLI version which can be found here.
