lua-mosquitto

=============

Lua bindings to the [libmosquitto](http://www.mosquitto.org/) client library.

The parameters to all functions are as per [libmosquitto's api](http://mosquitto.org/api)

only with sensible defaults for optional values, and return values directly

rather than via pointers.

Generated API documentation for the lua functions [is also available](docs/)

([Direct link if you are within github](https://flukso.github.io/lua-mosquitto/docs))

Compile

-------

You need Lua and mosquitto development packages (headers and libs) to

build lua-mosquitto.

Compile with

    make

You can override the pkg-config package name to set a specific Lua version.

For example:

    make LUAPKG=lua5.2

Example usage

-------------

Here is a very simple example that subscribes to the broker $SYS topic tree

and prints out the resulting messages:

```Lua

mqtt = require("mosquitto")

client = mqtt.new()

client.ON_CONNECT = function()

        print("connected")

        client:subscribe("$SYS/#")

        local mid = client:subscribe("complicated/topic", 2)

end

client.ON_MESSAGE = function(mid, topic, payload)

        print(topic, payload)

end

broker = arg[1] -- defaults to "localhost" if arg not set

client:connect(broker)

client:loop_forever()

```

Here is another simple example that will just publish a single message,

"hello", to the topic "world" and then disconnect.

```Lua

mqtt = require("mosquitto")

client = mqtt.new()

client.ON_CONNECT = function()

        client:publish("world", "hello")

        local qos = 1

        local retain = true

        local mid = client:publish("my/topic/", "my payload", qos, retain)

end

client.ON_PUBLISH = function()

	client:disconnect()

end

broker = arg[1] -- defaults to "localhost" if arg not set

client:connect(broker)

client:loop_forever()

```
