# Actors.jl

Concurrent computing in Julia with actors.

`Actors` implements the [Actor Model](https://en.wikipedia.org/wiki/Actor_model) of computation:

> An actor ... in response to a message it receives, can concurrently:
>
> - send a finite number of messages to other actors;
> - create a finite number of new actors;
> - designate the behavior to be used for the next message it receives.

`Actors` make(s) concurrency easy to understand and reason about and integrate(s) well with Julia's multi-threading and distributed computing. It provides an API for writing [reactive](https://www.reactivemanifesto.org) applications, that are:

- *responsive*: react to inputs and events,
- *message-driven*: rely on asynchronous message-passing,
- *resilient*: can cope with failures,
- *elastic*: can distribute load over multiple threads and  workers.

## Greeting Actors

The following example defines two behavior functions: `greet` and `hello` and spawns two actors with them. `sayhello` will forward a message to `greeter`, get a greeting string back and deliver it as a result:

```julia
julia> using Actors

julia> import Actors: spawn

julia> greet(greeting, msg) = greeting*", "*msg*"!" # a greetings server
greet (generic function with 1 method)

julia> hello(greeter, to) = request(greeter, to)    # a greetings client
hello (generic function with 1 method)

julia> greeter = spawn(greet, "Hello")              # start the server with a greet string
Link{Channel{Any}}(Channel{Any}(sz_max:32,sz_curr:0), 1, :default)

julia> sayhello = spawn(hello, greeter)             # start the client with a link to the server
Link{Channel{Any}}(Channel{Any}(sz_max:32,sz_curr:0), 1, :default)

julia> request(sayhello, "World")                   # request the client
"Hello, World!"

julia> request(sayhello, "Kermit")
"Hello, Kermit!"
```
