Public Instance Methods

formatted_usage(klass, namespace = true, subcommand = false) click to toggle source

Returns the formatted usage by injecting given required arguments and required options into the given usage.

# File bundler/vendor/thor/lib/thor/command.rb, line 41
def formatted_usage(klass, namespace = true, subcommand = false)
  if ancestor_name
    formatted = "#{ancestor_name} ".dup # add space

  end
  formatted ||= "#{klass.namespace.split(':').last} ".dup if subcommand

  formatted ||= "".dup

  Array(usage).map do |specific_usage|
    formatted_specific_usage = formatted

    formatted_specific_usage += required_arguments_for(klass, specific_usage)

    # Add required options
    formatted_specific_usage += " #{required_options}"

    # Strip and go!

run(instance, args = []) click to toggle source

By default, a command invokes a method in the thor class. You can change this implementation to create custom commands.

def run(instance, args = [])
  arity = nil

  if private_method?(instance)
    instance.class.handle_no_command_error(name)
  elsif public_method?(instance)
    arity = instance.method(name).arity
    instance.__send__(name, *args)
  elsif local_method?(instance, :method_missing)
    instance.__send__(:method_missing, name.to_sym, *args)
  else
    instance.class.handle_no_command_error(name)
  end
rescue ArgumentError => e
  handle_argument_error?(instance, e, caller) ? instance.class.handle_argument_error(self, e, args, arity) : (raise e)
