Class Methods

register(type#parse, #default, *classes::Class*)self#⚙

Registers type for parsing command-line arguments for Ruby values whose class is any of classes. The type should respond to #parse(String), which should convert its String argument into a Ruby value, and may optionally respond to #default, which should return the default value of the type, if any.

Example: Registering a New Type 
require 'pathname'

module My::Pathname
  Ame::Types.register self, Pathname

  def parse(argument)
    Pathname(argument)
  end
end
Example: Using a New Type as a Type 
class Rm < Ame::Root
  …
  splus 'FILE', My::Pathname, 'File to remove'
  def rm(pathnames)
    pathnames.each do |e| e.rmtree end
  end
end
Example: Using a New Types as a Default 
class My < Ame::Root
  optional 'CONFIG', Pathname('/etc/my/config'), 'Configuration file to use'
