Wrote a ruby script for the lan at xijio::blog

Basically it takes a number of teams and a number of players (or alternatively a comma seperated list of names (no spaces)) and prints out random teams. I wrote it in about an hour so if it has bugs, tell me and I might fix them but it seems to work for my purposes. Use it however you like but I’d prefer if you left the junk on top

#!/usr/bin/env ruby
#This script takes a number of teams and a number of players and makes random teams.
#It was created on Friday August 24, 2007 by Marshall Bjerke for a LAN Party
#It is licensed under the Creative Commoons License
#Usage is like this:
def print_usage()
puts "./teamgen.rb <number> ([<number>]|[PlayerName1, PlayerName2])"
puts "or"
puts ""
puts "ex1: ./teamgen.rb 3 10"
puts "ex2: ./teamgen.rb 3 jon,bob,RAUL4LIFE,frank,J1mmi3,will,,sam,poppaj,SaMbY"</number></number>

end

case ARGV.length

when 0, 1 #not enough args, send help
print_usage()

when 2
num_teams = ARGV[0]
players = ARGV[1]
if num_teams.match('^\d*$') then #num_teams is a number, continue
if players.match('^\d*$') then #use player numbers
arr_players = []
players.to_i.times do |number|
arr_players.push("Player" + number.to_s)
end

else #use passed player names
arr_players = ARGV[1].split(',')
end
num_players = arr_players.length
puts "There are #{num_players} players and #{num_teams} teams."
small_team_size = num_players.to_i / num_teams.to_i
big_team_size = small_team_size.to_i + 1
num_big_teams = num_players % num_teams.to_i
num_small_teams = num_teams.to_i - num_big_teams

# Print a few stats for the user
if (num_big_teams != 0) then
puts "That means there will be #{num_big_teams} team(s) of #{big_team_size} player(s) each and #{num_small_teams} team(s) of #{small_team_size} player(s) each."
else
puts "That means there will be #{num_small_teams} team(s) of #{small_team_size} player(s) each."
end

#initialize the teams array with empty arrays

end

#figure out the current team size
if (remaining_big_teams > 0) then
cur_team_size = big_team_size
remaining_big_teams -= 1
else
cur_team_size = small_team_size
end

#Build the team arrays by popping players off of the player array randomly
cur_team_size.times do |i|
teams[team_number].push(arr_players.delete_at(rand(arr_players.length)))#cool huh?
end
end

team_num = 0 #initialize it so we can keep count
teams.each do |team|
#Print the team number
team_info = "Team #{team_num} (#{team.length} players): \n"
player_num = 0 #initialize so we can keep count
team.each do |player|
#add the player name
team_info << "#{player}"
#then add a comma if they're not the last one
if (player_num < (team.size - 1)) then
team_info << ", "
end
player_num += 1 #increment for next player
end
#everyone loves linebreaks <img src='http://xijio.com/blog/wp-includes/images/smilies/icon_smile.gif' alt=':)' class='wp-smiley' /> 
team_info << "\n\n"

#output the team info
puts team_info
team_num += 1 #increment for next team
end

else #Oops, help the user out
puts "Number of teams not valid: #{num_teams}"
print_usage()
end

else #they passed a goofy number of arguments
print_usage()
end

edit: This script I used to display the code is really cool! Check it out here.

That code looks really badly formatted in your rss feed. It looks about 95 lines too long :P
