Ergo: Erlang-inspired event driven actor framework in Go

> ... a command-line utility designed to simplify the process of generating boilerplate code for your project based on the Ergo Framework

Why is there any boiler plate code at all? Why isn't hello world just a five line programme that spawns and sends hello world somewhere 5 times?

I've been thinking for years that if a project existed like this for Python it would take over the world. Golang is close, I guess.

It looks like a close copy of Erlang APIs, albeit with the usual golang language limitations and corresponding boilerplate and some additional stuff.

Most interesting to me is it has integration with actual Erlang processes. That could fill a nice gap as Erlang lacks in some areas like media processing - so you could use this to handle those kind of CPU bound / native tasks.

  func (a *actorA) HandleMessage(from gen.PID, message any) error {
    switch message.(type) {
      case doCallLocal:
        local := gen.Atom("b")
        a.Log().Info("making request to local process %s", local)
        if result, err := a.Call(local, MyRequest{MyString: "abc"}); err == nil {
          a.Log().Info("received result from local process %s: %#v", local, result)
        } else {
          a.Log().Error("call local process failed: %s", err)
        }
        a.SendAfter(a.PID(), doCallRemote{}, time.Second)
        return nil

That golang is a mess, and demonstrates just what a huge conceptual gap there really is between the two. Erlang relies on many tricks to end up greater than the sum of its parts, like how receiving messages is actually pattern matching over a mailbox, and using a tail recursive pattern to return the next handling state. You could conceivably do that in golang syntax but it will be horrible and absolutely not play nicely with the golang runtime.
