Cognitive Complexity
Cognitive Complexity is a measure of how difficult a unit of code is to intuitively understand. Unlike Cyclomatic Complexity, which determines how difficult your code will be to test, Cognitive Complexity tells you how difficult your code will be to read and comprehend.
A method's cognitive complexity is based on a few simple rules:
- Code is not considered more complex when it uses shorthand that the language provides for collapsing multiple statements into one
- Code is considered more complex for each "break in the linear flow of the code"
- Code is considered more complex when "flow breaking structures are nested"

This cop identifies places where a case-insensitive string comparison
can better be implemented using casecmp

'ABC'.eql? str.upcase
str.downcase == str.downcase

This cop checks for the formatting of empty method definitions.
By default it enforces empty method definitions to go on a single
line (compact style), but it can be configured to enforce the end
to go on its own line (expanded style).
Note: A method definition is not considered empty if it contains comments.
Example: EnforcedStyle: compact (default)
# bad

end
def self.foo(bar)
end
# good
def foo(bar); end
def foo(bar)
# baz
end
def self.foo(bar); end

This cop can check for array literals made up of symbols that are not using the %i() syntax.
Alternatively, it checks for symbol arrays using the %i() syntax on projects which do not want to use that syntax.
Configuration option: MinSize
If set, arrays with fewer elements than this value will not trigger the
cop. For example, a MinSize of
3` will not enforce a style on an array
of 2 or fewer elements.
Example: EnforcedStyle: percent (default)
# good
%i[foo bar baz]
# bad
[:foo, :bar, :baz]
Example: EnforcedStyle: brackets
# good
[:foo, :bar, :baz]
# bad

This cop checks for the presence of parentheses around ternary
conditions. It is configurable to enforce inclusion or omission of
parentheses using EnforcedStyle
. Omission is only enforced when
removing the parentheses won't cause a different behavior.
Example: EnforcedStyle: requirenoparentheses (default)
# bad
foo = (bar?) ? a : b
foo = (bar.baz?) ? a : b
foo = (bar && baz) ? a : b
# good
foo = bar? ? a : b
foo = bar.baz? ? a : b
foo = bar && baz ? a : b
Example: EnforcedStyle: require_parentheses
# bad
foo = bar? ? a : b
foo = bar.baz? ? a : b
foo = bar && baz ? a : b
# good
foo = (bar?) ? a : b
foo = (bar.baz?) ? a : b
foo = (bar && baz) ? a : b
Example: EnforcedStyle: requireparentheseswhen_complex
# bad
foo = (bar?) ? a : b
foo = (bar.baz?) ? a : b
foo = bar && baz ? a : b
# good
foo = bar? ? a : b
foo = bar.baz? ? a : b
