Build a Custom Trigger

Let's make a simple time interval trigger for a hello world sublayer agent

• # bash
  mkdir hello_world_agent
  cd hello_world_agent
  touch Gemfile
  touch hello_world_agent.rb
  touch time_interval.rb
  

• # Gemfile
  source 'https://rubygems.org'
  gem 'sublayer', '~>0.1.0'
  

• # bash
  bundle install
  

• Build a sublayer generator with the following description:

  • "A Time Interval Trigger that takes an integer for seconds to wait"

• Paste the result from above into time_interval.rb (rename and adjust arguments if needed)

• Write the following code in hello_world_agent.rb:

  # hello_world_agent.rb
  require "sublayer"
  require "./time_interval.rb"
  
  class HelloWorldAgent < Sublayer::Agents::Base
    trigger TimeInterval.new(2)
  
    goal_condition { false }
  
    check_status {}
  
    step do
      puts "hello world"
    end
  end
  
  HelloWorldAgent.new.run
  

  Adjust the name of the TimeInterval class and the arguments as needed!

• Run your code:

  ruby hello_world_agent.rb
