Tofu while and for loops

While loops

On Tofu, you can define the start and end of a while loop block with the keywords while and endwhile. A while loop runs a block of code until a condition is no longer met:

int num, 0

while num < 10
  print $num
  calcint num, $num + 1
endwhile
print It's done!

In this piece of code, the variable num will be printed and then incremented by one until its value reaches 10.

You can interrupt and cancel a loop execution with the keyword break:

int c, 0
while $c < 3
  print C: $c
  calcint c, $c + 1
  break
endwhile

Only one instance of this loop runs because the keyword break cancels futher executions, including any lines inside the loop block that are below it.

For loops

A foor loop lets you iterate through the elements of an array to process them from start to finish. You can use the for keyword and pass an array to it to begin processing your whole array:

array a1
arradd a1, text1
arradd a1, text2
arradd a1, text3

for i in a1
  print $i
endfor

This script will print "text1", "text2" and "text3".
