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)
