Webgen::SourceHandler::Copy

Simple source handler for copying files from the source tree, either verbatim or by applying a content processor.

Public Instance Methods

content(node) click to toggle source

Return either the preprocessed content of the node or the IO object for the node's source path depending on the node type.

# File lib/webgen/sourcehandler/copy.rb, line 29
def content(node)
  io = website.blackboard.invoke(:source_paths)[node.node_info[:src]].io
  if node.node_info[:preprocessor]
    is_binary = website.blackboard.invoke(:content_processor_binary?, node.node_info[:preprocessor])
    context = Webgen::Context.new(:content => io.data(is_binary ? 'rb' : 'r'), :chain => [node])
    website.blackboard.invoke(:content_processor, node.node_info[:preprocessor]).call(context)
    context.content
  else
    io
  end
end
create_node(path) click to toggle source

Create the node for path. If the path has the name of a content processor as the first part in the extension, it is preprocessed.

# File lib/webgen/sourcehandler/copy.rb, line 13
def create_node(path)
  if path.ext.index('.')
    processor, *rest = path.ext.split('.')
    if website.blackboard.invoke(:content_processor_names).include?(processor)
      path.ext = rest.join('.')
    else
      processor = nil
    end
  end
  super(path) do |node|
    node.node_info[:preprocessor] = processor
  end
end
