#title: Sheet All-Needle Cast-On (python with knitout module)
# Casts on a sheet by knitting all needles and then stacking front and back stitches to produce a decorative welt.

import knitout
K = knitout.Writer('1 2 3 4 5 6');
K.addHeader('Machine', 'Kniterate');

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

#Bring in carrier:
K.ingripper(carrier)

#On Kniterate machines, carriers start on the left,
#so will start by tucking all needles left-to-right,
#and will be sure to tuck the rightmost back-bed needle last.

#Need to use quarter-pitch racking to tuck all needles in one pass:
K.rack(0.5)

for n in range(min, max+1, 1):
	K.tuck("+", 'f' + str(n), carrier)
	K.tuck("+", 'b' + str(n), carrier)

#Return to aligned racking:
K.rack(0)

#Do a row of plain knitting on the front and back:
for n in range(max, min-1, -1):
	K.knit("-", 'f' + str(n), carrier)
for n in range(min, max+1, 1):
	K.knit("+", 'b' + str(n), carrier)
#One can knit more on the front or back beds here to make a larger "welt" at the edge.

#Stack back-bed stitches with front-bed stitches:
for n in range(min, max+1, 1):
	K.xfer('b' + str(n), 'f' + str(n))

#knit two plain rows through the stacked stitches to return carrier to the right edge:
for n in range(max, min-1, -1):
	K.knit("-", 'f' + str(n), carrier)
for n in range(min, max+1, 1):
	K.knit("+", 'f' + str(n), carrier)


#...now can knit on [min,max].
