Method: Thor::Base::ClassMethods#start

Defined in:
lib/thor/base.rb

#start(given_args = ARGV, config = {}) ⇒ Object

Parses the command and options from the given args, instantiate the class and invoke the command. This method is used when the arguments must be parsed from an array. If you are inside Ruby and want to use a Thor class, you can simply initialize it:

script = MyScript.new(args, options, config)
script.invoke(:command, first_arg, second_arg, third_arg)
