#Write header:

#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}")

#On SWGN2 machines, carriers start on the right,
#so will start tucking onto needles right-to-left:
for n in range(max, min-1, -1):
	#tuck alternating needles starting at the right edge:
	if (max - n) % 2 == 0:
		print(f"tuck - f{n} {carrier}")

#...continue clockwise around the tube to the back bed:
for n in range(min, max+1, 1):
	#note that adding 1+max-min preserves the alternating-needles pattern:
	if (1+max-min + n - min) % 2 == 0:
		print(f"tuck + b{n} {carrier}")

#...continue clockwise around the tube to the front bed and fill in needles missed the first time:
for n in range(max, min-1, -1):
	if (max - n) % 2 != 0:
		print(f"tuck - f{n} {carrier}")

#...finally, fill in the rest of the back bed:
for n in range(min, max+1, 1):
	if (1+max-min + n - min) % 2 != 0:
		print(f"tuck + b{n} {carrier}")

#now knit a row of plain knitting to let the cast-on stitches relax:
for n in range(max, min-1, -1):
	print(f"knit - f{n} {carrier}")
#send the yarn inserting hook out -- yarn should be well-enough held by the needles at this point.
print(f"releasehook {carrier}")
#finish the back of the row of plain knitting:
for n in range(min, max+1, 1):
	print(f"knit + b{n} {carrier}")

# ---- single jersey tube ----
#Create a single-jersey (all knits) tube:
for r in range(0, rows+1, 1):
	#knit front of tube going left:
	for n in range(max, min-1, -1):
		print(f"knit - f{n} {carrier}")
	#knit back of tube going right:
	for n in range(min, max+1, 1):
		print(f"knit + b{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}")
for n in range(min, max+1, 1):
	print(f"drop b{n}")
