def format_subsystem(s)
- Read upRead up
- Exclude checks
This cop checks whether method definitions are separated by one empty line.
NumberOfEmptyLines
can be and integer (e.g. 1 by default) or
an array (e.g. [1, 2]) to specificy a minimum and a maximum of
empty lines.
AllowAdjacentOneLineDefs
can be used to configure is adjacent
one line methods definitions are an offense
Example:
# bad
def a
end
def b
end
Example:
# good
def a
end
def b

Redundant return

- Exclude checks
This cop checks for redundant return
expressions.
Example:
def test
return something
end
def test

return something
end
It should be extended to handle methods whose body is if/else or a case expression with a default branch.
Surrounding space missing in default value assignment. Open
def hardware(severity=nil, msg=nil, &block)
- Read upRead up
- Exclude checks
Checks that the equals signs in parameter default assignments have or don't have surrounding space depending on configuration.
Example:
# bad
def some_method(arg1=:default, arg2=nil, arg3=[])
# do something...
end
# good
def some_method(arg1 = :default, arg2 = nil, arg3 = [])
# do something...
end
Do not use space inside array brackets. Open
transition from: :fanning, to: [ :idle ]
- Read upRead up
- Exclude checks
Checks that brackets used for array literals have or don't have surrounding space depending on configuration.
Example: EnforcedStyle: space
# The `space` style enforces that array literals have
# surrounding space.
# bad
array = [a, b, c, d]
# good
array = [ a, b, c, d ]
Example: EnforcedStyle: no_space
# The `no_space` style enforces that array literals have
# no surrounding space.
# bad
array = [ a, b, c, d ]
# good
array = [a, b, c, d]
Example: EnforcedStyle: compact
# The `compact` style normally requires a space inside
# array brackets, with the exception that successive left
# or right brackets are collapsed together in nested arrays.
# bad
array = [ a, [ b, c ] ]
# good
array = [ a, [ b, c ]]

Missing top-level class documentation comment. Open
class Controller
- Read upRead up
- Exclude checks
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
class Person
# ...

def toggle(switch)
- Read upRead up
- Exclude checks
This cops checks for two or more consecutive blank lines.

some_method
# good

# one empty line

Use &&

. Open
if @logdev.nil? or (severity < @level and subsystem < @subsystem)
- Read upRead up
- Exclude checks
This cop checks for uses of and
and or
, and suggests using &&
and
|| instead
. It can be configured to check only in conditions, or in
all contexts.
Example: EnforcedStyle: always (default)
# bad
foo.save and return
# bad
if foo and bar
end
# good
foo.save && return
# good
if foo && bar
end
Example: EnforcedStyle: conditionals
# bad
if foo and bar
end
# good
foo.save && return
# good
foo.save and return
# good
if foo && bar

Favor modifier if
usage when having a single-line body. Another good alternative is the usage of control flow &&
/||
. Open
if message.nil? && block_given?
- Read upRead up
- Exclude checks
Checks for if and unless statements that would fit on one line
if written as a modifier if/unless. The maximum line length is
configured in the Metrics/LineLength
cop.
Example:
# bad
if condition
do_stuff(bar)
end
unless qux.empty?
Foo.do_something
end
# good
do_stuff(bar) if condition
Foo.do_something unless qux.empty?
%w
-literals should be delimited by [
and ]
. Open
SUBSYSTEM_LABEL = %w(HARDWARE STATE_MACHINE CONTROLLER SENSOR THERMOSTAT NONE QUIET).each(&:freeze).freeze
- Read upRead up
- Exclude checks
This cop enforces the consistent usage of %
-literal delimiters.
Specify the 'default' key to set all preferred delimiters at once. You can continue to specify individual preferred delimiters to override the default.
Example:
# Style/PercentLiteralDelimiters:
# PreferredDelimiters:
# default: '[]'
# '%i': '()'
# good
%w[alpha beta] + %i(gamma delta)
# bad
%W(alpha #{beta})
# bad
%I(alpha beta)
Pass __FILE__
and __LINE__
to eval
method, as they are used by backtraces. Open
mod.module_eval %Q-
def #{state}?
current_state == "#{state}"
end
-
- Read upRead up
- Exclude checks
This cop checks eval
method usage. eval
can receive source location
metadata, that are filename and line number. The metadata is used by
backtraces. This cop recommends to pass the metadata to eval
method.
Example:
# bad
eval <<-RUBY
def do_something
end
RUBY
# bad
C.class_eval <<-RUBY
def do_something
end
RUBY
# good
eval <<-RUBY, binding, __FILE__, __LINE__ + 1
def do_something
end
RUBY
# good
C.class_eval <<-RUBY, __FILE__, __LINE__ + 1
def do_something
end

This cop checks for single-line method definitions that contain a body. It will accept single-line methods with no body.
