lwes_pure

LWES - Light Weight Event System protocol implemented in pure ruby. The original lwes gem is a thin wrapper around the c library, and does not handle data types for dynamic LWES events. This gem allows users to define the data type of attributes in an clear way, so that your LWES event listeners will be happy. This library includes the following components:

Lwes::Event for reading from and writing to IO objects.
Lwes::Emitter for emitting LWES events through UDP socket.

Installation

gem install lwes_pure

Initialization

If only Lwes::Event is needed, require like this:

require 'lwes/event'

If both Lwes::Event and Lwes::Emitter are needed, require like this:

require 'lwes'

Usage

Here is a short example to create an event and send it off using udp

# requiring lwes_pure gem
require 'lwes'

# create a LWES emitter
emitter = Lwes::Emitter.new({
  :host => "127.0.0.1",
  :port => "12345"
})

# create a LWES event with 3 attributes of type int16, string, and ip array
event = Lwes::Event.new({
  :name => "Test::Event",
  :attributes => {
    'int_attribute' => [:int16, 123],
    'string_attribute' => [:attr_str, "test string"],
    'ip_attribute' => [:ip_v4_array, ["1.2.3.4", "5.6.7.8", "192.168.0.255"]]
  }
})

# send it off with the emitter
emitter.emit event

Future works

Implement Listener
Better error handling
