and one with switches.
Receives an array of args and returns two arrays, one with arguments

  arguments = []

    arguments << item

Raises an error if @non_assigned_required array is not empty.

Takes an array of Thor::Argument objects.

  @switches = arguments
  arguments.each do |argument|

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 = []
  array << shift while current_is_value?
  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(":", 2)
    raise MalformattedArgumentError, "You can't specify '#{key}' more than once in option '#{name}'; got #{key}:#{hash[key]} and #{key}:#{value}" if hash.include? key
    hash[key] = value
  end
  hash
end

def parse_numeric(name)


Otherwise raises an error.
Check if the peek is included in enum if enum is provided.
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
  value = $&.index(".") ? shift.to_f : shift.to_i
  if @switches.is_a?(Hash) && switch = @switches[name]
    if switch.enum && !switch.enum.include?(value)
      raise MalformattedArgumentError, "Expected '#{name}' to be one of #{switch.enum.join(', ')}; got #{value}"
    end
  end
  value
end

def parse_string(name)


Check if the peek is included in enum if enum is provided. Otherwise raises an error.
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
    value = shift
    if @switches.is_a?(Hash) && switch = @switches[name]
      if switch.enum && !switch.enum.include?(value)
        raise MalformattedArgumentError, "Expected '#{name}' to be one of #{switch.enum.join(', ')}; got #{value}"
