hollaback gem to add callbacks to

class CLI < Thor class_before :say_hello class_after :say_goodbye desc 'first_test', 'First test command' around :say def first_test puts 'How are you?' end desc 'second_test', 'Second test command' def second_test puts 'How are you?' end no_commands do def say_hello puts 'Hello!' end def say_goodbye puts 'Goodbye!' end def say puts 'Speaking...' yield puts '...done.' end end end
When invoked, the above CLI results with:
irb(main):001:0> CLI.start(['first_test']) Hello! Speaking... How are you? ...done. Goodbye! => nil
