This is a OS X command line tool to create a permalink from a string

perma

#!/usr/bin/env ruby
options = Array.new
string = String.new
permalink = String.new
pbcopy = "cbcopy"

if RUBY_PLATFORM =~ /darwin/ then
  pbcopy = "pbcopy"
end

ARGV.each do|a|
  if a[0,1] == '-' then
    options << a
  else
    string = a
  end
end

if string.empty? then
  puts "You must provide a string to transform"
  exit
end

permalink = string.downcase.gsub(/\b+/, " ").gsub(/[^a-z0-9\s]+/i, '').strip.gsub(/\s+/, '-')

if !permalink.empty? then
  puts permalink
  IO.popen(pbcopy, 'w+') {|clipboard| clipboard.write(permalink)}
