Overview

This class represents the configuration of the RuboCop application and all its cops. A Config is associated with a YAML configuration file from which it was read. Several different Configs can be used during a run of the rubocop program, if files in several directories are inspected.

#base_dir_for_path_parametersObject

Paths specified in configuration files starting with .rubocop are relative to the directory where that file is. Paths in other config files are relative to the current directory. This is so that paths in config/default.yml, for example, are not relative to RuboCop’s config directory since that wouldn’t work.
