resolving and instantiating non imported packages with --run and --macro include

Question

I've been using the --run command, and have been trying to include some packages when running it, using --macro include like this:

haxe -lib nape --macro include('nape.geom.Vec2') --run Main 'nape.geom.Vec2'

and then use Type.resolve so I can instantiate them with Type.createInstance like so:

class Main 
{
  static function main() 
  {
    trace("hello", Sys.args());
    var c = Type.resolveClass(StringTools.replace(Sys.args()[0], "'", ""));
    trace(c);
    Type.createInstance(c, []);
  }
}

I've also tried to use --interp with this command:

haxe -lib nape --macro include('nape.geom.Vec2') -main Main --interp -D nape.geom.Vec2

They both run, trace, and receive the Sys.args as expected for --run (with a small code change to accommodate '-D nape.geom.Vec2' for interp), but resolveClass always returns null, so I cant pass it to creatInstance without an error.

I'm using haxe 3.4.2 stable

What am I doing wrong? Is this possible with the --run command or --interp commands?

Id really love some more complete documentation on some of these features

Answer 1

Ok, so I got it working by linking the individual classes I require, and disabling dead code elimination (as suggested above by Jonas Malaco)

Using the code from the original post, and this build command:

haxe -lib nape nape.geom.Vec2 -dce no --run Main 'nape.geom.Vec2'
