Haxe WebIDL
This library allows to access any C++ library from Haxe/JS (using Emscripten or Web Assembly) and Haxe/HashLink by simply defining an idl file.
For a complete example, see the sample
Installing
git clone https://github.com/ncannasse/webidl.git # Clone the repo
haxelib dev webidl webidl # Set the webidl package install directory to the cloned repoUsage
Given the following IDL file describing a C++ library:
interface Point {
attribute long x;
attribute long y;
void Point();
void Point( long x, long y );
[Operator="*",Ref] Point op_add( [Const,Ref] Point p );
double length();
};And the following Haxe code (strictly typed thanks to IDL definitions):
class Sample {
public static function main() {
var p1 = new Point();
p1.x = 4;
p1.y = 5;
var p2 = new Point(7,8);
var p = p1.op_add(p2);
trace('Result = ${p.x},${p.y} len=${p.length()}');
p1.delete();
p2.delete();
p.delete();
}
}This compiles to the following Javascript:
// Generated by Haxe 4.0.0
(function () { "use strict";
var Sample = function() { };
Sample.main = function() {
var this1 = _eb_Point_new0();
var p1 = this1;
_eb_Point_set_x(p1,4);
_eb_Point_set_y(p1,5);
var this2 = _eb_Point_new2(7,8);
var p2 = this2;
var p = _eb_Point_op_add1(p1,p2);
console.log("Result = " + _eb_Point_get_x(p) + "," + _eb_Point_get_y(p) + " len=" + _eb_Point_length0(p));
_eb_Point_delete(p1);
_eb_Point_delete(p2);
_eb_Point_delete(p);
};
Sample.main();
})();Haxe webidl can be used for both Haxe/JS and Haxe/HashLink, the cpp bindings generated are the same for both platforms.
