Class Method Details

Config accessor for HtmlSlicer. Accepts argument as a style.

# File 'lib/html_slicer/config.rb', line 41

def self.config(style = nil)
  eval("@config#{"_#{style}" if style}") || raise("Config style '#{style}' is invalid.")
end

.configure(style = nil) {|eval("@config#{"_#{style}" if style} ||= #{style ? "@config.duplicate" : "Configuration.new"}")| ... } ⇒ Object

Configures global settings for HtmlSlicer

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
  config.param_name = :any_other_param_name
end

Passing an argument (:symbol) creates stylized configuration, which can be used like that:

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

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

  • Missing options are inherited from global one.
