A quick ruby script that takes a series of player names as command line arguments and pairs them up with each other in random fashion. Example usage: > ruby player_selector.rb Bob John Jim Billy George

player_selector.rb

require 'active_support/core_ext/string/inflections'
require 'colorize'

players = ARGV.clone

raise 'You must specify players (separated by spaces) as parameters.' and exit(1) unless players.count > 0

until players.count == 0
  player1, player2 = players.shuffle!.slice!(0,2)
  player2 ||= "Bot(AI)"
  puts player1.titleize.blue + " is paired with ".light_white + player2.titleize.blue
