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 https://github.com/ibilon/MonoExport.git
.
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++ files with -D monoexport-out=filename
.
You can also configure the name used in the include statement of the cpp file with -D monoexport-include=filename
.
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.
@:monoExport
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
, or optionally haxe MyHaxeClass -lib monoexport -cs output -D monoexport-out=custom
.
#include "MonoExport.hpp"
int main() {
MonoExport::init("output/bin/output.dll");
MonoExport::MyHaxeClass::sayHello("John");
MonoExport::MyHaxeClass::sayHello("John");
MonoExport::clean();
}
If you used a custom output filename change the include to "custom.hpp"
Compile it (on linux) with g++ MonoExport.cpp main.cpp $(pkg-config --cflags --libs mono-2) -o host
.
Adapt the first cpp filename to custom.cpp
in case of custom output filename.
Running it, ./host
, will print:
MyHaxeClass.hx:5: Hello John!
MyHaxeClass.hx:5: Hello again John!
