Tag parsing in ruby

tag_parser.rb

#!/usr/bin/env ruby

tag_samples = [ 'foo bar', 'foo, bar, baz', 'foo "fun times" stuff', '"fail", "foo times"', "foo 'this is fun' bar" ]

tag_samples.each do |tag_str|
  tags = tag_str.scan(/(\w+)|("([^"]+)")|('([^']+)')/).map { |a, _, b, _, c| (a or b or c).strip }
  puts "#{tag_str}:"
  puts tags
end

I'd like it to work for single quotes as well as double quote.

'big balls' is equivalent to "big balls"

It does now.
