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"

Unused method argument - options. If it's necessary, use _ or _options as an argument name to indicate that it won't be used.

This cop checks for unused method arguments.

Example:

# bad

def some_method(used, unused, _unused_but_allowed)
  puts used
end

Example:

# good

def some_method(used, _unused, _unused_but_allowed)
  puts used
end

Unused method argument - options. If it's necessary, use _ or _options as an argument name to indicate that it won't be used. You can also write as list(*) if you want the method to accept any arguments but don't care about them.

Put one space between the method name and the first argument.
Open

      if servers.include?alias_name
Severity: Minor
Found in lib/sshez/exec.rb by rubocop

Checks that exactly one space is used between a method name and the first argument for method calls without parentheses.

Alternatively, extra spaces can be added to align the argument with something on a preceding or following line, if the AllowForAlignment config parameter is true.

Example:

# bad
something  x
something   y, z
something'hello'

# good
something x
something y, z
something 'hello'

Put one space between the method name and the first argument.

Unused block argument - key. If it's necessary, use _ or _key as an argument name to indicate that it won't be used.
Open

      options.file_content.each_pair do |key, value|
Severity: Minor

do_something do |bar|
  puts :foo
end

define_method(:foo) do |bar|

Example:

#good

do_something do |used, _unused|
