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 checks that the cyclomatic complexity of methods is not higher than the configured maximum. The cyclomatic complexity is the number of linearly independent paths through a method. The algorithm counts decision points and adds one.
An if statement (or unless or ?:) increases the complexity by one. An else branch does not, since it doesn't add a decision point. The && operator (or keyword and) can be converted to a nested if statement, and ||/or is shorthand for a sequence of ifs, so they also add one. Loops can be said to have an exit condition, so they add one.

case kind
- Read upRead up
- Exclude checks
This cops checks for indentation that doesn't use the specified number of spaces.
See also the IndentationConsistency cop which is the companion to this one.
Example:
# bad
class A
def test
puts 'hello'
end
end
# good
class A
def test
puts 'hello'
end
end
Example: IgnoredPatterns: ['^\s*module']
# bad
module A
class B
def test
puts 'hello'
end
end
end
# good
module A
class B
def test
puts 'hello'

- Read upRead up
- Exclude checks
This cop checks for chaining of a block after another block that spans multiple lines.
Example:
Thread.list.find_all do |t|

Prefer annotated tokens (like %<foo>s</foo>

Use a consistent style for named format string tokens.
Note:
unannotated
style cop only works for strings
which are passed as arguments to those methods:
sprintf
, format
, %
.
The reason is that unannotated format is very similar
to encoded URLs or Date/Time formatting strings.
Example: EnforcedStyle: annotated (default)
# bad
format('%{greeting}', greeting: 'Hello')
format('%s', 'Hello')
# good
format('%<greeting>s', greeting: 'Hello')</greeting>
Example: EnforcedStyle: template
# bad
format('%<greeting>s', greeting: 'Hello')
format('%s', 'Hello')
# good
format('%{greeting}', greeting: 'Hello')</greeting>
Example: EnforcedStyle: unannotated
# bad
format('%<greeting>s', greeting: 'Hello')
format('%{greeting}', 'Hello')
# good
format('%s', 'Hello')</greeting>

Prefer the use of lambda.call(...)
over lambda.(...)
. Open
H.path_matcher(path).(key, value) ? [k, λ.(value)] : [k, value]
- Read upRead up
- Exclude checks
This cop checks for use of the lambda.(args) syntax.

# bad lambda.(x, y)
# good lambda.call(x, y)
Example: EnforcedStyle: braces
# bad lambda.call(x, y)

Redundant self
detected. Open
self.tap { |this| this[key.first] = value }
- Read upRead up
- Exclude checks
This cop checks for redundant uses of self
.
The usage of self
is only needed when:
Sending a message to same object with zero arguments in presence of a method name clash with an argument or a local variable.
Calling an attribute writer to prevent an local variable assignment.
Note, with using explicit self you can only send messages with public or protected scope, you cannot send private messages this way.
Note we allow uses of self
with operators because it would be awkward
otherwise.
Example:
# bad
def foo(bar)
self.baz
end
# good
def foo(bar)
self.bar # Resolves name clash with the argument.
end
def foo
bar = 1
self.bar # Resolves name clash with the local variable.
end
def foo
%w[x y z].select do |bar|
self.bar == bar # Resolves name clash with argument of the block.
end
end
