This cop is designed to help upgrade to 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
in 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: when_needed (default)
# The `when_needed` style will add the frozen string literal comment
# to files only when the `TargetRubyVersion` is set to 2.3+.
# bad
module Foo
# ...
end
# good
# frozen_string_literal: true
module Foo
# ...
end
Example: EnforcedStyle: always
# 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

Example: EnforcedStyle: never

Missing top-level class documentation comment. Open

This cop checks for missing top-level documentation of classes and modules. Classes with no body are exempt from the check and so are namespace modules - modules that have nothing in their bodies except classes, other modules, or constant definitions.
The documentation requirement is annulled if the class or module has a "#:nodoc:" comment next to it. Likewise, "#:nodoc: all" does the same for all its children.
Example:
# bad
class Person
# ...
end
# good
# Description/Explanation of Person class

This cop makes sure that all methods use the configured style, snake_case or camelCase, for their names.
Example: EnforcedStyle: snake_case (default)
# bad
def fooBar; end
# good
def foo_bar; end
Example: EnforcedStyle: camelCase
# bad

Use warn
instead of $stderr.puts
to allow such output to be disabled. Open
$stderr.puts(*args) if debug?
- Read upRead up
- Create a ticketCreate a ticket
- Exclude checks
This cop identifies places where $stderr.puts
can be replaced by
warn
. The latter has the advantage of easily being disabled by,
e.g. the -W0 interpreter flag, or setting $VERBOSE to nil.
Example:
# bad
$stderr.puts('hello')
# good
warn('hello')
Avoid rescuing without specifying an error class. Open
rescue => e

- Exclude checks
This cop checks for rescuing StandardError
. There are two supported
styles implicit
and explicit
. This cop will not register an offense
if any error other than StandardError
is specified.
Example: EnforcedStyle: implicit
# `implicit` will enforce using `rescue` instead of
# `rescue StandardError`.
# bad
begin
foo
rescue StandardError
bar
end
# good
begin
foo
rescue
bar
end
# good
begin
foo
rescue OtherError
bar
end
# good
begin
foo
rescue StandardError, SecurityError

end
Example: EnforcedStyle: explicit (default)
# `explicit` will enforce using `rescue StandardError`
# instead of `rescue`.
# bad
begin
foo
rescue
bar
end
# good
begin
foo

This cop checks for parentheses in the definition of a method, that does not take any arguments. Both instance and class/singleton methods are checked.
Example:
