Question

I’d like to detect the target language in Haxe so that I can change a function’s behavior depending on which language Haxe has been compiled to.

Example in Haxe-like pseudocode:

class Test() {
static function printStuff(toPrint) {
    if (the target language is Java) {
        System.out.println(toPrint);
    } else if (the target language is C++) {
        cout << toPrint;
    } else if (the target language is JavaScript) {
        alert(toPrint);
    }

}
}

Is it currently possible to achieve this in Haxe?

Answer 1

You can use conditional compilation along with Haxe Magic to achieve this. For example:

#if java
    untyped __java__("java.lang.System.out.println(toPrint);");
#elseif js
    untyped __js__("alert(toPrint);");
#elseif ...
    ...
#end
