    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"

    # == Schema Information
    Severity: Minor
    Found in app/models/project.rb by rubocop

    This cop is designed to help upgrade to Ruby 3.0. It will add the comment # frozen_string_literal: true to the top of files to enable frozen string literals. Frozen string literals may be default in Ruby 3.0. The comment will be added below a shebang and encoding comment. The frozen string literal comment is only valid in Ruby 2.3+.

    Example: EnforcedStyle: when_needed (default)

    # The `when_needed` style will add the frozen string literal comment
# to files only when the `TargetRubyVersion` is set to 2.3+.
# bad
module Foo
  # ...
end

# good
# frozen_string_literal: true

module Foo
  # ...
end

    Example: EnforcedStyle: always

    # The `always` style will always add the frozen string literal comment
# to a file, regardless of the Ruby version or if `freeze` or `<<` are
# called on a string literal.
# bad
module Bar
  # ...
end

# good
# frozen_string_literal: true

module Bar

    Example: EnforcedStyle: never

    # The `never` will enforce that the frozen string literal comment does
# not exist in a file.

    Provide an exception class and message as arguments to fail.

        fail ActiveRecord::RecordInvalid.new(self) if Author.count > 0
    Severity: Minor
    Found in app/models/author.rb by rubocop

    This cop checks the args passed to fail and raise. For exploded style (default), it recommends passing the exception class and message to raise, rather than construct an instance of the error. It will still allow passing just a message, or the construction of an error with more than one argument.

    The exploded style works identically, but with the addition that it will also suggest constructing error objects when the exception is passed multiple arguments.

    Example: EnforcedStyle: exploded (default)

    # bad
raise StandardError.new("message")

# good
raise StandardError, "message"
fail "message"
raise MyCustomError.new(arg1, arg2, arg3)
raise MyKwArgError.new(key1: val1, key2: val2)

    Example: EnforcedStyle: compact

    # bad
raise StandardError, "message"
raise RuntimeError, arg1, arg2, arg3

# good
raise StandardError.new("message")
raise MyCustomError.new(arg1, arg2, arg3)
fail "message"

    Favor modifier if usage when having a single-line body. Another good alternative is the usage of control flow &&/||.

    Found in app/models/item_image.rb by rubocop

    Checks for if and unless statements that would fit on one line if written as a modifier if/unless. The maximum line length is configured in the Metrics/LineLength cop.

    Example:

    # bad
if condition
  do_stuff(bar)
end

unless qux.empty?
  Foo.do_something
end

# good
do_stuff(bar) if condition
Foo.do_something unless qux.empty?

    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 of3` 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]
