Control Flow

Control flow is trivial and easy to get a handle on in Scar, is it is much like Python or any other imperative programming language.

if

var x = 10

if x == 10:
    print "Will print."

while

while x < 10:
    print "Do some action..."

for .. to

for i = 0 to 10:
    print "%d" | i

for |options|

for i32 x = 1; x < 20; x += 2:
    print "odd: %d" | x

foreach

Currently only applicable to iteration through map types, for example a type of map[string: string]

map[int: string] x = [1: "hello", 2: "world"]

put!(x, 3, "new value")
put!(y, "new key", "new value")
put!(y, "2", "some other value value")

foreach (string z in x.values):
    print "Value: %s" | z

reverse

reverse for i = 10 to 1:
    print "Countdown: %d" | i

break

reverse for i = 10 to 1:
    if i == 5:
        break
    print "Countdown: %d" | i

continue

reverse for i = 10 to 1:
    if i == 5:
        continue
    print "Countdown: %d" | i

try, catch and throw

try:
    some_risky_thing()
catch:
    throw 1
