something I’m working on right now

def shrink():
	mov (r8, 0)   # index
	mov (r9, r1)  # input -> hold
	geti (r9, 0)  # last character
	mov (r10, 0)  # count
	mov (r2, "")  # result
	push (r1)
	call (len)
	pop (r11)     # length

	def add_char():
		# convert it into a character first
		add (r10, 32)
		push (r10)
		call (chr)
		pop (r10)
		# add it to the result
		add (r2, r9)
		add (r2, r10)
		# reset everything
		mov (r9, r3)
		mov (r10, 0)

	while true:
		mov (r3, r1)
		geti (r3, r8)
		cmp (r9, r3)
		if neql:
			goto (add_char)
		# increment
		add (r10, 1)
		add (r8, 1)
		# check if it's the right size
		cmp (r8, r11)
		if eql:
			goto (add_char)
			break
