require 'console'

## reopen the String class and add #display_width and
## #display_slice methods directly to strings.
##
## If you include "console/string", you can call
##   "能吞a".display_width
## instead of
##   Console.display_width "能吞a"
##
## and
##
##   "能吞a".display_slice 0, 2
## instead of
##   Console.display_slice "能吞a", 0, 2
##

class String
  ## Returns the display width of the string. See Console.display_width for details.
  def display_width; Console.display_width self end

  ## Returns a substring according to display-based start and offset values. See
  ## Console.display_slice for what this means.
  ##
  ## :call-seq:
  ##   display_slice(start, offset=1, pad_string=" ")
  ##
  ## (rdoc fail)
  def display_slice(*a); Console.display_slice self, *a end
