Control Flow

Other than JavaScript’s if (x) y and while (x) y or do x while (y), Nonstraightforward has its own control flow.

Conditional statement

Conditional statements are done with stipulate that the provision x qualifies y where x is a condition and y is a statement or block.

stipulate that the provision 1 === "1" qualifies {
    ~/dev/stdout/write/ln("your runtime is broken");
}

Exceptions

Exceptions can be used normally with the throw keyword, or the far superior retaliate keyword.

Loops

While loops

While-loops are done with so long as the condition x is still upholding, then do y.

mutable readwrite variable i = 0;
so long as the condition i < 10 is still upholding, then do {
    ~/dev/stdout/write/ln(['i = ', i].join(""));
    i += 1;
}

Do-while loops

There is no Nonstraightforward do-while syntax yet, so do/while is the only option right now.

For loops

Not supported yet. Trust me, it’s painful not having them.

Pattern matching

Nonstraightforward has JavaScript’s switch statement. The match statement is also planned to be added.

Exceptions

I (raiseafloppafan3925) consider exceptions as a method of control flow. Not always a good one but it does change your execution flow. Exceptions can be thrown with either throw or retaliate.

try/catch/finally does not exist in Nonstraightforward, instead there is undertake/capture/eventually.

undertake {
    stipulate that the provision ~/dev/random > 0.5 qualifies {
        retaliate "apple";
    }
} capture error {
    ~/dev/stderr/write/ln("Bad " .. error .. "!!!");
} eventually {
    ~/dev/stdout/write/ln("done!");
}

A lone undertake statement cannot exist and must be accompanied by a capture.
