a quck'n'dirty prototype for chaining more than one command to a key/modifier combination for the zephyros window manager.

zephyros.rb

require '/Applications/Zephyros.app/Contents/Resources/libs/zephyros.rb'
require 'time'

@last_time = Time.now - 10
@times = 0

##
# Simply returns a Proc instance with the passed block.
def command
  Proc.new
end

##
# Binds a list of Proc objects to a specific key/modifier combination. You can
# iterate over them by pressing the key/modifier combination repeatedly.
def bind_chained_commands(key, modifiers, chained_commands=[])
	API.bind key, modifiers do
		index_in_chain = index_in_chain chained_commands.size
		chained_commands[index_in_chain].call
	end
end

##
# Returns an increasing index number when called continously with a delay <= 1s.
#
# Pass number_of_commands to limit the maximum index returned.
def index_in_chain(number_of_commands=0)
	now = Time.now

	if @last_time >= now - 1
		# Iterate through the chain
		@times += 1
		@times = 0 if number_of_commands <= @times
	else 
		# Begin a new chain iteration
		@times = 0
	end

	@last_time = now

	return @times
end


bind_chained_commands 'D', ['Cmd', 'Shift'], [
	command {
		API.alert 'proc 1'
	}, command {
		API.alert 'proc 2'
	}, command {
		API.alert 'proc 3'
	}
]
