# = generator.rb: convert an internal iterator to an external one
#
# Copyright (c) 2001,2003 Akinori MUSHA <knu@iDaemons.org>

#
# == Overview
#
# This library provides the Generator class, which converts an
# internal iterator (i.e. an Enumerable object) to an external
# iterator.  In that form, you can roll many iterators independently.
#
# The SyncEnumerator class, which is implemented using Generator,
# makes it easy to roll many Enumerable objects synchronously.
#
# See the respective classes for examples of usage.


#
# Generator converts an internal iterator (i.e. an Enumerable object)
# to an external iterator.
#
# Note that it is not very fast since it is implemented using
# continuations, which are currently slow.
#
# == Example
#
#   require 'generator'
#
#   # Generator from an Enumerable object
#   g = Generator.new(['A', 'B', 'C', 'Z'])
#
#   while g.next?
#     puts g.next
#   end
#
#   # Generator from a block
#   g = Generator.new { |g|
#     for i in 'A'..'C'
#       g.yield i
#     end
#
#     g.yield 'Z'
#   }
#
#   # The same result as above
#   while g.next?
#     puts g.next
#   end
#   
class Generator
  include Enumerable

  # Creates a new generator either from an Enumerable object or from a
  # block.
  #
  # In the former, block is ignored even if given.
  #
  # In the latter, the given block is called with the generator
  # itself, and expected to call the +yield+ method for each element.
  def initialize(enum = nil, &block)
    if enum
      @block = proc { |g|

  # Returns the element at the current position.

  # Note that enumeration sequence by next method does not affect other
  # non-external enumeration methods, unless underlying iteration
  # methods itself has side-effect, e.g. IO#each_line.
