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"

Checks that block braces have or don't have surrounding space inside them on configuration. For blocks taking parameters, it checks that the left brace has or doesn't have trailing space depending on configuration.
Example: EnforcedStyle: space (default)
# The `space` style enforces that block braces have
# surrounding space.
# bad
some_array.each {puts e}
# good
some_array.each { puts e }
Example: EnforcedStyle: no_space
# The `no_space` style enforces that block braces don't
# have surrounding space.
# bad
some_array.each { puts e }
# good
some_array.each {puts e}
Example: EnforcedStyleForEmptyBraces: no_space (default)
# The `no_space` EnforcedStyleForEmptyBraces style enforces that
# block braces don't have a space in between when empty.
# bad
some_array.each { }
some_array.each { }
some_array.each { }

Example: EnforcedStyleForEmptyBraces: space

This cop checks whether the end keywords are aligned properly.
Three modes are supported through the EnforcedStyleAlignWith
configuration parameter:
If it's set to keyword
(which is the default), the end
shall be aligned with the start of the keyword (if, class, etc.).
If it's set to variable
the end
shall be aligned with the
left-hand-side of the variable assignment, if there is one.
If it's set to start_of_line
, the end
shall be aligned with the
start of the line where the matching keyword appears.
Example: EnforcedStyleAlignWith: keyword (default)
# bad
variable = if true
end
# good
variable = if true
end
Example: EnforcedStyleAlignWith: variable
# bad
variable = if true
end
# good
