Control Flow Statements¶

Basically, you can control the flow of your Pineapple code with any of the following:

if , elif and else
for loop
while loop
break , continue or return

If-elif-else statements¶

Similar to Python, all you need is indentation (tab), you don't need those curly brackets. For example:

if he.isCrazy
    you.callAmbulance

elif he.isInDanger
    you.goHelp(he)

else
    you.doNothing

Note

Every test expression must have type of Boolean.

Tips

.isCrazy and other similar construct are just functions.

Test expression chaining¶

Sometimes, a single test expression is not enough to express what you really wanted. In such situation, you can use the following functions:

.and
.or
.not

For example:

if he.isYoung.and(he.isNaughty)
    "He is a kid".show

elif sky.isBlue.or(air.isFresh)
    "I am happy!".show

elif current.isLunchTime.not
    "Continue working . . .".show

For statements¶

For statements is used to iterate over a list.
For example:

1 2	for x in [1,2,3,4] x.show

While loop¶

While loop is use to loop some code until certain condition is met.

1 2	while not file.atEOF file.readline.show
