shiftOut command missing

[eadmaster]

i've seen it is commented in the code, is there a fork/branch with this command implemented?

I'd like to use a bunch of these common 74HC595 Shift Registers in my code.

UPDATE: i've managed to port this piece of code from Johnny Five ,seems to work correctly, so no need to add a command:

def pyfirmata_shift_out(board, data_pin, clock_pin, value, is_big_endian=False):
	# derived from https://github.com/rwaldron/johnny-five/blob/main/lib/board.js#L560
	for i in range(8):
		board.digital[clock_pin].write(0)
		if is_big_endian:
			b = int(bool(value & (1 << (7 - i))))
		else:
			b = int(bool(value & (1 << i)))
		board.digital[data_pin].write(b)
		board.digital[clock_pin].write(1)
        

def update_bar_display(value):
	# open latch to fill register with data
	board.digital[LEDBAR_SHIFTREG_LATCH_PIN].write(0)
	
	def convert_to_bits_on(num):
		result = 0
		for i in range(num):
			result |= 1 << i
		return result
	
	#print("real value", value)
	value = int(value/9)
	if value>7:
		value=7
	#print("real value", value)
	value = convert_to_bits_on(value)
	
	pyfirmata_shift_out(board, LEDBAR_SHIFTREG_DATA_PIN, LEDBAR_SHIFTREG_CLOCK_PIN, value, True)
	
	# close latch to commit bits into register.
	board.digital[LEDBAR_SHIFTREG_LATCH_PIN].write(1)
