Thor::Hollaback

Build Status Gem Version

Adds callbacks to thor commands.

Installation

Add this line to your application's Gemfile:

gem 'thor-hollaback'

And then execute:

$ bundle

Or install it yourself as:

$ gem install thor-hollaback

Usage

Uses the hollaback gem to add callbacks to thor commands. You can set CLI-level callbacks with the macros class_before, class_after, and class_around. You can set command-level callbacks with before, after, and around. Example below.

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

and

irb(main):001:0> CLI.start(['second_test'])
Hello!
How are you?
Goodbye!
=> nil

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.
