Controls Flow

In ocypode we will have this controls flow:

• if - The if statement is used to execute a block of code if a condition is true.
• else if - The else if statement is used to execute a block if the condition is false and its condition is true.
• else - The else statement is used to execute a block if all the conditions (if/else if) is false.
• switch - The switch statement is used to execute a block of code depending on the value of a variable.
• for - The for statement is used to execute a block of code a certain number of times.
• while - The while statement is used to execute a block of code while a condition is true.
• loop - The loop statement is used to execute a block of code until is breaked.
• break - The break statement is used to break a loop.

All the control flow statements are expressions, so they can be used as values. (the last expression of the block will be the value of the expression)

All the syntaxes are subject to change. Until the first release.

The examples may be contain a unimplemented function, but they will be implemented in the future.

if/else if/else

This example shows how to use the if/else if/else statements.

~get_stage<age>{<
    return if<lt<age><12>>{<
        "You are a child"
    >}
    else if<lt<age><20>>{<
        "You are a teenager"
    >}
    else{<
        "You are an adult"
    >};
>}

~main<argc><argv>{<
    println<foo<10>>; // prints: You are a child
    println<foo<19>>; // prints: You are a teenager
    println<foo<30>>; // prints: You are an adult
>}

You can also print it directly:

~main<argc><argv>{<
    age = 23;
    println<
        if<lt<age><12>>{<
            "You are a child"
        >}
        else if<lt<age><20>>{<
            "You are a teenager"
        >}
        else{<
            "You are an adult"
        >}
    >;
>}

while

This example shows how to use the while statement.

~main<argc><argv>{<
    counter = 0;
    while<lt<counter.copy<>><10>>{<
        println<counter.copy<>>;
        counter = add<counter><1>;
    >}
>}

loop/break

This example shows how to use the loop and break statement.

~main<argc><argv>{<
    counter = 0;
    // prints 1, 2, 3, 4, 6, 7, 8, 9, 10
    loop{<
        counter = add<counter><1>;
        if<eq<counter.copy<>><10>>{<
            break;
        >} else if<ne<counter.copy<>><5>>{<
            println<counter.copy<>>;
        >};
    >}
>}
