This cop checks for extra/unnecessary whitespace.
Example:
# good if AllowForAlignment is true
name = "RuboCop"
# Some comment and an empty line
website += "/rubocop-hq/rubocop" unless cond
puts "rubocop" if debug
# bad for any configuration
set_app("RuboCop")
website = "https://github.com/rubocop-hq/rubocop"
# good only if AllowBeforeTrailingComments is true
object.method(arg) # this is a comment
# good even if AllowBeforeTrailingComments is false or not set
object.method(arg) # this is a comment
# good with either AllowBeforeTrailingComments or AllowForAlignment
object.method(arg) # this is a comment
another_object.method(arg) # this is another comment
some_object.method(arg) # this is some comment

This cop is designed to help upgrade to after Ruby 3.0. It will add the
comment # frozen_string_literal: true
to the top of files to
enable frozen string literals. Frozen string literals may be default
after Ruby 3.0. The comment will be added below a shebang and encoding
comment. The frozen string literal comment is only valid in Ruby 2.3+.
Example: EnforcedStyle: always (default)
# The `always` style will always add the frozen string literal comment
# to a file, regardless of the Ruby version or if `freeze` or `<<` are
# called on a string literal.
# bad
module Bar
# ...
end
# good
# frozen_string_literal: true
module Bar
# ...
end
Example: EnforcedStyle: never
# The `never` will enforce that the frozen string literal comment does
# not exist in a file.
# bad
# frozen_string_literal: true
module Baz
# ...
end
# good
module Baz
# ...
