# repeater.rb : Implements repeated page elements.

module Prawn

    # A list of all repeaters in the document.

# @group Experimental API

# Provides a way to execute a block of code repeatedly based on
    # a page_filter.  Since Stamp is used under the hood, this method is very
    # space efficient.
    #
    # Available page filters are:
    #   :all        -- repeats on every page
    #   :odd        -- repeats on odd pages
    #   :even       -- repeats on even pages
    #   some_array  -- repeats on every page listed in the array
    #   some_range  -- repeats on every page included in the range
    #   some_lambda -- yields page number and repeats for true return values
    #
    # Also accepts an optional second argument for dynamic content which
    # executes the code in the context of the filtered pages without using
    # a Stamp.
    #
    # Example:
    #
    #   Prawn::Document.generate("repeat.pdf", :skip_page_creation => true) do
    #
    #     repeat :all do
    #       draw_text "ALLLLLL", :at => bounds.top_left
    #     end
    #
    #     repeat :odd do
    #       draw_text "ODD", :at => [0,0]
    #     end
    #
    #     repeat :even do
    #       draw_text "EVEN", :at => [0,0]
    #     end
    #
    #     repeat [1,2] do
    #       draw_text "[1,2]", :at => [100,0]
    #     end
    #
    #     repeat 2..4 do
    #       draw_text "2..4", :at => [200,0]
    #     end
    #
    #     repeat(lambda { |pg| pg % 3 == 0 }) do
    #       draw_text "Every third", :at => [250, 20]
    #     end
    #
    #     10.times do
    #       start_new_page
    #       draw_text "A wonderful page", :at => [400,400]
    #     end
    #
    #     repeat(:all, :dynamic => true) do
    #       text page_number, :at => [500, 0]
    #     end
    #
    #   end
