#Parameters:
min = 1 #needle number of left edge
max = 20 #needle number of right edge
rows = 20 #number of rows to knit
carrier = "3" #carrier name

# ---- set up initial loops and yarn carrier ----
#Bring in carrier:
print(f"inhook {carrier}")
#Set stitch table entry for cast-on:
print(f"x-stitch-number 101")

#On SWGN2 machines, carriers start on the right,
#so will start tucking onto needles right-to-left,
#and will be sure to tuck the rightmost needle in the first pass:
for n in range(max, min-1, -1):
	#tuck alternating needles, making sure to do the right edge:
	if (max - n) % 2 == 0:
		print(f"tuck - f{n} {carrier}")
#now, moving left-to-right, tuck the needles that were not tucked on the first pass:
for n in range(min, max+1, 1):
	if (max - n) % 2 != 0:
		print(f"tuck + f{n} {carrier}")
#Set stitch table entry for knitting:
print(f"x-stitch-number 105")
#knit two plain rows to allow cast-on stitches to relax:
# two isn't set in stone here -- it's just convenient
# for this example code to have the carrier end up on the right.
for n in range(max, min-1, -1):
	print(f"knit - f{n} {carrier}")
#send out yarn inserting hook; it is no longer needed to hold the yarn in place:
print(f"releasehook {carrier}")
for n in range(min, max+1, 1):
	print(f"knit + f{n} {carrier}")

# ---- single jersey sheet ----
#Create a single-jersey (all knits) sheet by alternating left- and right-going rows of knits:
for r in range(0, rows+1, 1):
	if r % 2 == 0:
		#left-going row:
		for n in range(max, min-1, -1):
			print(f"knit - f{n} {carrier}")
	else:
		#right-going row:
		for n in range(min, max+1, 1):
			print(f"knit + f{n} {carrier}")

# ---- take carrier out and drop remaining loops ----
#Take carrier out with yarn inserting hook:
print(f"outhook {carrier}")

#drop loops:
for n in range(min, max+1, 1):
	print(f"drop f{n}")
