Constructor Details

#initialize(opts = {}, &block) ⇒ Interpreter

Call with a block to evaluate a dynamic config. The only method exposed for you is ‘add` to add a link to the sitemap object attached to this interpreter.

Options

  • link_set - a LinkSet instance to use. Default is SitemapGenerator::Sitemap.

All other options are passed to the LinkSet by setting them using accessor methods.

def initialize(opts={}, &block)
  opts = SitemapGenerator::Utilities.reverse_merge(opts, :link_set => SitemapGenerator::Sitemap)
  @linkset = opts.delete :link_set
  @linkset.send(:set_options, opts)
  eval(&block) if block_given?
end

Class Method Details

.run(opts = {}, &block) ⇒ Object

Run the interpreter on a config file using the default SitemapGenerator::Sitemap sitemap object.

Options

  • :config_file - full path to the config file to evaluate. Default is config/sitemap.rb in your application’s root directory.

All other options are passed to new.

      instance_eval(&block)
    end
  end
end

#group(*args, &block) ⇒ Object

Start a new group of sitemaps. Any of the options to SitemapGenerator.new may be passed. Pass a block with calls to add to add links to the sitemaps.

All groups use the same sitemap index.

#sitemap ⇒ Object
