It is possible to embed C/C++/Objective-C code in JTransc. Using @HaxeMeta and using hxcpp tricks.
Example: https://github.com/jtransc/jtransc-examples/blob/master/cpp/src/example/Test.java
public class Test {
static public void main(String[] args) {
System.out.println(Demo.mysum(7, 3));
}
}
@HaxeMeta("@:cppInclude('./../test.c')")
@HaxeAddFilesTemplate("test.c")
class Demo {
@HaxeMeta("@:noStack")
@HaxeMethodBody(target = "cpp", value = "return untyped __cpp__('::sum({0}, {1})', p0, p1);")
static native public int mysum(int a, int b);
}
