module Webgen::PathHandler::PageUtils

This module should be used by path handlers that need to work with paths in Webgen Page Format.

Note that this modules provides an implementation for the parse_meta_info! method. If you also include the Base module, make sure that you include it before this module! Also make sure to override this method if you need custom behaviour!

Public Instance Methods

parse_meta_info!(path) click to toggle source

Calls parse_as_page! to update the meta information hash of path. Returns the found blocks which will be passed as second parameter to the create_nodes method.

# File lib/webgen/path_handler/page_utils.rb, line 134
def parse_meta_info!(path)
  parse_as_page!(path)
end

Private Instance Methods

parse_as_page!(path) click to toggle source

Assume that the content of the given path is in Webgen Page Format and parse it. Updates 'path.meta_info' with the meta info from the page and returns the content blocks.

# File lib/webgen/path_handler/page_utils.rb, line 140
def parse_as_page!(path)
  begin
    page = Webgen::Page.from_data(path.data)
  rescue Webgen::Page::FormatError => e
    raise Webgen::Error.new("Error reading source path: #{e.message}", nil, path)
  end
  blocks = page.meta_info.delete('blocks') || {}
  path.meta_info.merge!(page.meta_info)
  blocks.each {|key, val| ((path.meta_info['blocks'] ||= {})[key] ||= {}).merge!(val)}
  page.blocks
end

set_blocks(node, blocks) click to toggle source

Set the blocks (see parse_as_page!) for the node.

# File lib/webgen/path_handler/page_utils.rb, line 154
def set_blocks(node, blocks)
  node.node_info[:blocks] = blocks
end
