Module: Webgen::SourceHandler::Base::OutputPathHelpers

Included in:
Webgen::SourceHandler::Base
Defined in:
lib/webgen/sourcehandler/base.rb

Overview

This module is used for defining all methods that can be used for creating output paths.

All public methods of this module are considered to be output path creation methods and must have the following parameters:

parent

the parent node

path

the path for which the output name should be created

use_lang_part

controls whether the output path name has to include the language part

Instance Method Details

#standard_output_path(parent, path, use_lang_part, style = path.meta_info['output_path_style']) ⇒ Object

Default method for creating an output path for parent and source path.

The automatically set parameter style (which uses the meta information output_path_style from the path’s meta information hash) defines how the output name should be built (more information about this in the user documentation).
