You can have repeated "attributes" calls count as a single "branch".
For this purpose, attributes are any method with no argument; no attempt
is meant to distinguish actual attr_reader
from other methods.
Example: CountRepeatedAttributes: false (default is true)
# `model` and `current_user`, referenced 3 times each,
# are each counted as only 1 branch each if
# `CountRepeatedAttributes` is set to 'false'
def search
@posts = model.active.visible_by(current_user)
.search(params[:q])
@posts = model.some_process(@posts, current_user)
@posts = model.another_process(@posts, current_user)
render 'pages/search/page'

Group together all attr_accessor
attributes. Open
attr_accessor :data
- Read upRead up
- Exclude checks
Checks for grouping of accessors in class
and module
bodies.
By default it enforces accessors to be placed in grouped declarations,
but it can be configured to enforce separating them in multiple declarations.
NOTE: If there is a method call before the accessor method it is always allowed as it might be intended like Sorbet.
Example: EnforcedStyle: grouped (default)
# bad
class Foo
attr_reader :bar
attr_reader :bax
attr_reader :baz
end
# good
class Foo
attr_reader :bar, :bax, :baz
end
# good
class Foo
# may be intended comment for bar.
attr_reader :bar
sig { returns(String) }
attr_reader :bax
may_be_intended_annotation :baz
attr_reader :baz
end
Example: EnforcedStyle: separated
# bad
class Foo
attr_reader :bar, :baz
end
# good
class Foo

Checks for if

The maximum line length is configured in the Layout/LineLength
cop. The tab size is configured in the IndentationWidth
of the
Layout/IndentationStyle
cop.
One-line pattern matching is always allowed. To ensure that there are few cases
where the match variable is not used, and to prevent oversights. The variable x
becomes undefined and raises NameError
when the following example is changed to
the modifier form:

NOTE: It is allowed when defined?

Checks for usage of comparison operators (==
,
>
, <
) to test numbers as zero, positive, or negative.
These can be replaced by their respective predicate methods.
This cop can also be configured to do the reverse.
This cop can be customized allowed methods with AllowedMethods
.
By default, there are no methods to allowed.
This cop disregards #nonzero?
as its value is truthy or falsey,
but not true
and false
, and thus not always interchangeable with
!= 0
.
This cop allows comparisons to global variables, since they are often
populated with objects which can be compared with integers, but are
not themselves Integer
polymorphic.
Safety:
This cop is unsafe because it cannot be guaranteed that the receiver defines the predicates or can be compared to a number, which may lead to a false positive for non-standard classes.
Example: EnforcedStyle: predicate (default)
# bad
foo == 0
0 > foo
bar.baz > 0
# good

Example: EnforcedStyle: comparison

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, constant definitions or constant visibility declarations.
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.
