The +type is assumed to be string. If you want a required hash with default values +as option, you can use method_option which uses a more declarative style: + + method_option :attributes, :type => :hash, :default => {}, :required => true + +All arguments can be set to nil (except required arguments), by suppling a no or +skip variant. For example: + + thor app name --no-attributes + +In previous versions, aliases for options were created automatically, but now +they should be explicit. You can supply aliases in both short and declarative +styles: + + method_options %w( force -f ) => :boolean + +Or: + + method_option :force, :type => :boolean, :aliases => "-f" + +You can supply as many aliases as you want. + +NOTE: Type :optional available in Thor 0.9.0 was deprecated. Use :string or :boolean instead. + +== Namespaces + +By default, your Thor tasks are invoked using Ruby namespace. In the example +above, tasks are invoked as: + + thor app:install name --force + +However, you could namespace your class as: + + module Sinatra + class App < Thor + # tasks + end + end + +And then you should invoke your tasks as: + + thor sinatra:app:install name --force + +If desired, you can change the namespace: + + module Sinatra + class App < Thor + namespace :myapp + # tasks + end + end + +And then your tasks hould be invoked as: + + thor myapp:install name --force + +== Invocations + +Thor comes with a invocation-dependency system as well which allows a task to be +invoked only once. For example: + + class Counter < Thor + desc "one", "Prints 1, 2, 3" + def one + puts 1 + invoke :two + invoke :three + end + + desc "two", "Prints 2, 3" + def two + puts 2 + invoke :three + end + + desc "three", "Prints 3" + def three + puts 3 + end + end + +When invoking the task one: + + thor counter:one + +The output is "1 2 3", which means that the three task was invoked only once. +You can even invoke tasks from another class, so be sure to check the +documentation. + +== Thor::Group + +Thor has a special class called Thor::Group. The main difference to Thor class +is that it invokes all tasks at once. The example above could be rewritten in +Thor::Group as this: + + class Counter < Thor::Group + desc "Prints 1, 2, 3" + + def one + puts 1 + end + + def two + puts 2 + end + + def three + puts 3 + end + end + +When invoked: + + thor counter + +It prints "1 2 3" as well. Notice you should describe (using the method desc) +only the class and not each task anymore. Thor::Group is a great tool to create +generators, since you can define several steps which are invoked in the order they +are defined (Thor::Group is the tool use in generators in Rails 3.0). + +Besides, Thor::Group can parse arguments and options as Thor tasks: + + class Counter < Thor::Group + # number will be available as attr_accessor + argument :number, :type => :numeric, :desc => "The number to start counting" + desc "Prints the 'number' given upto 'number+2'" + + def one + puts number + 0 + end + + def two + puts number + 1 + end + + def three + puts number + 2 + end + end + +The counter above expects one parameter and has the folling outputs: + + thor counter 5 + # Prints "5 6 7" + + thor counter 11 + # Prints "11 12 13" + +You can also give options to Thor::Group, but instead of using method_option +and method_options, you should use class_option and class_options. +Both argument and class_options methods are available to Thor class as well. + +== Actions + +Thor comes with several actions which helps with script and generator tasks. You +might be familiar with them since some came from Rails Templates. They are: +say, ask, yes?, no?, add_file, +remove_file, copy_file, template, directory, +inside, run, inject_into_file and a couple more. + +To use them, you just need to include Thor::Actions in your Thor classes: + + class App < Thor + include Thor::Actions + # tasks + end + +Some actions like copy file requires that a class method called source_root is +defined in your class. This is the directory where your templates should be +placed.
