and one with switches.
Receives an array of args and returns two arrays, one with arguments 
def self.split(args)
  arguments = []
  args.each do |item|
    break if item =~ /^-/
    arguments << item
  end
  return arguments, args[Range.new(arguments.size, -1)]

Raises an error if @non_assigned_required array is not empty.

      o.respond_to?(:switch_name) ? o.switch_name : o.human_name
    end.join("', '")

def initialize(arguments=[])


Takes an array of Thor::Argument objects. 
def initialize(arguments=[])
  @assigns, @non_assigned_required = {}, []
  @switches = arguments
  arguments.each do |argument|
    if argument.default
      @assigns[argument.human_name] = argument.default

def parse_array(name)


["a", "b", "c"]

And returns it as an array:

["a", "b", "c"]

found or a switch is found.
Runs through the argument array getting all strings until no string is 
def parse_array(name)
  return shift if peek.is_a?(Array)
  array = []
  while current_is_value?
    array << shift
  end
  array
end

def parse_hash(name)


{ "name" => "string", "age" => "integer" }

Becomes:

[ "name:string", "age:integer" ]

mark it as a hash:
Runs through the argument array getting strings that contains ":" and 
def parse_hash(name)
  return shift if peek.is_a?(Hash)
  hash = {}
  while current_is_value? && peek.include?(?:)
    key, value = shift.split(':')
    hash[key] = value
  end
  hash
end

def parse_numeric(name)


Otherwise raises an error.
Check if the peek is numeric format and return a Float or Integer. 
def parse_numeric(name)
  return shift if peek.is_a?(Numeric)
  unless peek =~ NUMERIC && $& == peek
    raise MalformattedArgumentError, "Expected numeric value for '#{name}'; got #{peek.inspect}"
  end
  $&.index('.') ? shift.to_f : shift.to_i
end

def parse_string(name)


for --no-string-arg, nil
for --string-arg, just return the current value in the pile
Parse string: 
def parse_string(name)
  if no_or_skip?(name)
    nil
  else
    shift
