Moving Elements in a Ruby Array by Name

Wed, 11/19/2008 - 12:36 by snuxoll   Tags:

    This is an extension to my previous tip about moving elements in ruby arrays around. In fact, this is yet another mixin that only has one line of real code, and even though it's quite obvious I thought I'd post it here.

# Adds the ability to reoder elements by name,
# it requires the object extended
# to support the Reorderable module and have
# a #index_of method
module NameReorderable
  # Moves an element around an orderable
  # list by its name
  def move_by_name(name, to)
    move(index(name), to)
  end
end
