Overview

Use RUBY for heredoc delimiter of example Ruby code.

Some editors may apply better syntax highlighting by using appropriate language names for the delimiter.

Examples:

# bad
expect_offense(<<~CODE)
  example_ruby_code
CODE

# good
expect_offense(<<~RUBY)
  example_ruby_code
RUBY

#add_global_offense	Adds an offense that has no particular location.
#add_offense	Adds an offense on the specified range (or node with an expression) Unless that offense is disabled for this range, a corrector will be yielded to provide the cop the opportunity to autocorrect the offense.
#begin_investigation	Called before any investigation.
#callbacks_needed,
#cop_config	Configuration Helpers.
#cop_name, #excluded_file?,
#external_dependency_checksum	This method should be overridden when a cop’s behavior depends on state that lives outside of these locations:
#inspect,
#message	Gets called if no message is specified when calling `add_offense` or `add_global_offense` Cops are discouraged to override this; instead pass your message directly.
