Actor initialization with parameters about comedy HOT 7 CLOSED

Custom actor parameters are not yet implemented in Comedy, but this feature should certainly be present.

There is, however, a resource injection mechanism in Comedy. It's not yet documented, but you can see examples in test/test-system.js ("should properly inject resources defined in contexts" and the like).

If shared resource is not what you need, you can try to get away with initialization message.

Yes but you have the same problem when you define your context:

class MyContext {
      initialize() {
        this.resource = myVariable;
      }

      getResource() {
        return this.resource;
      }
    }

myVariable is unknown

Yes, the context with all it's resources is supposed to be self-contained.

In your case, the initialization message would work. Custom actor parameters will be implemented shortly.

from comedy.

Implemented in v0.1.0. Here is an example test:

it('should be able to pass custom parameters to child actor', P.coroutine(function*() {
  class MyActor {
    initialize(selfActor) {
      this.helloResponse = selfActor.getCustomParameters().helloResponse;
    }

    hello() {
      return this.helloResponse;
    }
  }

  // Create child actor with custom parameter.
  var childActor = yield rootActor.createChild(MyActor, {
    mode: 'forked',
    customParameters: { helloResponse: 'Hi there!' }
  });

  var response = yield childActor.sendAndReceive('hello');

  expect(response).to.be.equal('Hi there!');
}));

Enjoy!

Works perfectly THANKS.

It seems that if I put a function in the parameters it works for non-forked actor but that functions are filtered out of the parameters when the actor is forked.
Any idea how to pass functions as parameters for forked actors ?

from comedy.

Well, yeah, for now I've just added support for plain objects in custom parameters. Class and function passing will be done in a next step (you can create an issue for that).
