# actix-lua

[![Build Status](https://travis-ci.org/poga/actix-lua.svg?branch=master)](https://travis-ci.org/poga/actix-lua)
[![Latest Version](https://img.shields.io/crates/v/actix-lua.svg)](https://crates.io/crates/actix-lua)
[![API Documentation](https://docs.rs/actix-lua/badge.svg)](https://docs.rs/actix-lua)

A safe scripting environment for [actix](https://github.com/actix/actix) with the [Lua Programming Language](https://www.lua.org).

## Synopsis

```rust
extern crate actix_lua;
use actix_lua::{LuaActorBuilder, LuaMessage};

fn main () {
    let addr = LuaActorBuilder::new()
        .on_handle_with_lua(r#"return ctx.msg + 42"#)
        .build()
        .unwrap()
        .start();

    let res = addr.send(LuaMessage:from(100));
    // return: 142
}
```

## Install

Add `actix-lua` to your `Cargo.toml`:

```toml
[dependencies]
actix-lua = "0.3"
```

## Example

Check [examples](https://github.com/poga/actix-lua/tree/master/examples) directory.

## Lua Actor

Use [`LuaActor`](https://docs.rs/actix-lua/latest/actix_lua/struct.LuaActor.html) to integrate Lua scripts to your system with actor model.

### Message

In actor model, actors communicate with messages. `LuaMessage` is the only message type accepted by `LuaActor`:

* `LuaMessage` can be converted to/from primitive types with `LuaMessage::from()`.
* Lua types(e.g. number, table) will be convert to `LuaMessage` automatically.

### Lua API

#### `ctx.msg`

The message sent to Lua actor.

#### `ctx.notify(msg)`

Send message `msg` to self.

#### `ctx.notify_later(msg, seconds)`

Send message `msg` to self after specified period of time.

#### `local recipient = ctx.new_actor(script_path, [actor_name])`

Create a new actor with given lua script. returns a recipient which can be used in `ctx.send` and `ctx.do_send`.

#### `local result = ctx.send(recipient, msg)`

Send message `msg` to `recipient asynchronously and wait for response.

Equivalent to `actix::Recipient.send`.

#### `ctx.do_send(recipient, msg)`

Send message `msg` to `recipient`.

Equivalent to `actix::Recipient.do_send`.

#### `ctx.terminate()`

Terminate actor execution.
