class RuboCop::Cop::Style::Copyright
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\d{3} 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.
Constants
