Compile IF / ELSE

IF / ELSE is a compile-time expression that allows you to conditionally include or exclude code from the final output.

IF <js-condition> {
    <...>
}

Examples

Basic

Code

IF 1 == 1 {
    say "Hello, world!"
}

Output

say "Hello, world!"

You can also use ELSE IF and ELSE to chain multiple conditions together.

IF <js-condition> {
    <...>
} ELSE IF <js-condition> {
    <...>
} ELSE {
    <...>
}

Examples

With ELSE IF

Code

IF 1 == 2 {
    say "Hello, world!"
} ELSE IF 1 == 1 {
    say "Goodbye, world!"
}

Output

say "Goodbye, world!"

With ELSE

Code

IF 1 == 2 {
    say "Hello, world!"
} ELSE {
    say "Goodbye, world!"
}

Output

say "Goodbye, world!"

With ELSE IF and ELSE

Code

IF 1 == 2 {
    say "Hello, world!"
} ELSE IF 1 == 3 {
    say "Goodbye, world!"
} ELSE {
    say "See you later, world!"
}

Output

say "See you later, world!"

IF / ELSE can be used in any context. So you can conditionally include functions, directories, and JSON files in the compiled output.

IF (config.debug) {
    dir debug {
        function do_debug_stuff {
            say "Debugging!"
        }

        loot_table debug_loot {
            ...
        }
    }
}
