Conditionals¶

Ooga Booga's IFF statement allows programs to take different paths based on a condition.

Basic if¶

IFF condition
    OOF body executes when condition is truthy
    SAY "condition was true"
UGHA

The condition can be any expression. UGHA closes the block.

If / else¶

IFF x BIGGR 0
    SAY "positive"
NOPE
    SAY "zero or negative"
UGHA

NOPE introduces the else branch. There is still only one UGHA for the whole if/else construct.

If / else-if / else¶

Chain multiple conditions with NOPE IFF:

IFF score BIGGR IS 90
    SAY "A"
NOPE IFF score BIGGR IS 80
    SAY "B"
NOPE IFF score BIGGR IS 70
    SAY "C"
NOPE
    SAY "F"
UGHA

Any number of NOPE IFF branches may be chained before the final NOPE.

Truthy and falsy¶

Ooga Booga is strongly typed — conditions must be GRUNT (bool) expressions. Use comparison operators to produce boolean values:

Expression	Result
`x BIGGR 0`	`YEAH` if x > 0, else `NAH`
`x IS 0`	`YEAH` if x equals 0
`YEAH`	Always `YEAH`
`NAH`	Always `NAH`

Non-boolean expressions used directly as conditions will produce a type error.

Nested conditionals¶

IFF x BIGGR 0
    IFF x SMALLR 100
        SAY "between 1 and 99"
    NOPE
        SAY "100 or more"
    UGHA
NOPE
    SAY "zero or negative"
UGHA

Each nested IFF has its own UGHA.

Compound conditions¶

Use AND, OR, and NOT to build compound conditions:

IFF x BIGGR 0 AND x SMALLR 10
    SAY "single digit positive"
UGHA

IFF x IS 0 OR x IS VOID
    SAY "nothing here"
UGHA

IFF NOT (x IS 0)
    SAY "x has a value"
UGHA
