Default global configuration options ↑

window = 4
outer_window = 0
left = 0
right = 0
param_name = :slice

Override/complete global configuration ↑

HtmlSlicer.configure do |config|
  config.slice = {:complete => /\s+|\z/, :maximum => 2000}
  config.resize = {:width => 300, :only => {:tag => 'iframe'}}
  config.window = 5

HtmlSlicer.configure(:paged) do |config|
  config.as = :page
  config.param_name = :page
end

class Post < ActiveRecord::Base
  slice :content, :config => :paged
end
