trap("SIGINT") { exit }

if ARGV.length < 2
  puts "Usage: #{$0} watch_folder sync_folder"
  puts "Example: #{$0} web keepInSync"
  exit
end

dev_extension = 'dev'
filetypes = ['css','html','htm','less','js', 'dart']

watch_folder = ARGV[0]
sync_folder = ARGV[1]

puts "Watching #{watch_folder} and subfolders for changes in project files..."
puts "Syncing with #{sync_folder}..."

while true do
  files = []
  filetypes.each {|type|
    files += Dir.glob( File.join( watch_folder, "**", "*.#{type}" ) )
  }
  new_hash = files.collect {|f| [ f, File.stat(f).mtime.to_i ] }
  hash ||= new_hash
  diff_hash = new_hash - hash

  unless diff_hash.empty?
    hash = new_hash

    diff_hash.each do |df|
      puts "Detected change in #{df[0]}, syncing..."
      system("rsync -avzh #{watch_folder} #{sync_folder}")
    end
  end

  sleep 1
end
