Event Support Mixin

1. Add this gem as a runtime dependency of your Logstash plugin's gemspec:

   Gem::Specification.new do |s|
     # ...
   
     s.add_runtime_dependency 'logstash-mixin-event_support'
   end

2. In your plugin code, require this library and include it into your plugin class that already inherits LogStash::Plugin:

   require 'logstash/plugin_mixins/event_support/event_factory_adapter'
   
   class LogStash::Codecs::Bar < Logstash::Codecs::Base
   
     include LogStash::PluginMixins::EventSupport::EventFactoryAdapter
   
     # an optional mixin to provide `events_from_json` using the factory :
     #include LogStash::PluginMixins::EventSupport::FromJsonHelper
   
     def decode(data, &block)
       payload = extract_bar(data) # ...
       yield event_factory.new_event(payload)
     end
   
     # def extract_bar(data) ...
   
   end

This gem:

• MUST remain API-stable at 1.x
• MUST NOT introduce additional runtime dependencies
