Defined in:
lib/rubocop/cop/style/copyright.rb

Overview

Check that a copyright notice was given in each source file.

The default regexp for an acceptable copyright notice can be found in config/default.yml. The default can be changed as follows:

Style/Copyright: Notice: '^Copyright ((c) )?2\d3 Acme Inc'

This regex string is treated as an unanchored regex. For each file that RuboCop scans, a comment that matches this regex must be found or an offense is reported.
