5.23 inline

since Haxe 4.0.0

The inline keyword can be used before a function call or a constructor call. This allows a finer-grained control of inlining, unlike the inline access modifier.

class Main {
  static function mid(s1:Int, s2:Int) {
    return (s1 + s2) / 2;
  }

  static public function main() {
    var a = 1;
    var b = 2;
    var c = mid(a, b);
    var d = inline mid(a, b);
  }
}

The generated JavaScript output is:

(function ($global) { "use strict";
var Test = function() { };
Test.mid = function(s1,s2) {
    return (s1 + s2) / 2;
};
Test.main = function() {
    var a = 1;
    var b = 2;
    var c = Test.mid(a,b);
    var d = (a + b) / 2;
};
Test.main();
})({});

Note that c produces a call to the function, whereas d does not. The usual warnings about what makes a good candidate for inlining still hold (see Inline).

An inline new call can be used to avoid creating a local class instance. See Inline Constructors for more details.
