Generate code used to launch a haxe executable from a c++ application

To install, run:

haxelib install monoexport 1.0.0 

See using Haxelib in Haxelib documentation for more information.


Generate code used to launch a haxe executable from a c++ application, using the mono runtime.

Annoted classes will have their static functions made available to c++.

The haxe "world" is not reset between calls, so you can store data in static variables, see the example for more details.


You can do either haxelib install monoexport or haxelib git monoexport



Add -lib monoexport to you hxml, and annotate the classes that should be exported with @:monoExport.

You can configure the name of the generated c++ file with -D monoexport-out=filename.hpp.

The following types are supported in argument/return values:

  • Bool
  • Int
  • Float
  • String
  • Array<Bool>
  • Array<Int>
  • Array<Float>
  • Array<String>


You need to compile with the mono runtime, you can find the required flags on linux with pkg-config --cflags --libs mono-2.

You just need to include the generated c++ file, init with MonoExport::init("path/to/haxe/cs.dll"); (Note: the dll will be named cs-Debug.dll when doing a debug build) and you can call haxe functions using the following syntax: MonoExport::HaxeClassName::functionname();.

Don't forget to clean the mono runtime at the end MonoExport::clean();.


You can find this example in the example/ folder.

class MyHaxeClass {
	static var first:Bool = true;
	public static function sayHello(name:String) {
		trace("Hello" + (first ? " " : " again ") + name + "!");
		first = false;

Compile it with haxe MyHaxeClass -lib monoexport -cs output.


include "MonoExport.hpp"

int main() {



Compile it (on linux) with `g++ main.cpp $(pkg-config --cflags --libs mono-2) -o host`.

Running it, `./host`, will print:

MyHaxeClass.hx:5: Hello John! MyHaxeClass.hx:5: Hello again John!
