Use the lambda method for multiline lambdas.
Open

   scope :with_memory_binds, -> do
Severity: Minor
Found in app/models/memory.rb by rubocop

This cop (by default) checks for uses of the lambda literal syntax for single line lambdas, and the method call syntax for multiline lambdas. It is configurable to enforce one of the styles for both single line and multiline lambdas as well.

Example: EnforcedStyle: linecountdependent (default)

# bad
f = lambda { |x| x }
f = ->(x) do
      x
    end

# good
f = ->(x) { x }
f = lambda do |x|
      x
    end

Example: EnforcedStyle: lambda

# bad
f = ->(x) { x }
f = ->(x) do
      x
    end

# good
f = lambda { |x| x }
f = lambda do |x|
      x
    end

Example: EnforcedStyle: literal

# bad
f = lambda { |x| x }
f = lambda do |x|
      x
    end

# good
f = ->(x) { x }
f = ->(x) do
      x
    end

Avoid the use of Perl-style backrefs.

            $1
Severity: Minor
Found in app/models/memory.rb by rubocop

This cop looks for uses of Perl-style regexp match backreferences like $1, $2, etc.

Example:

# bad
puts $1

# good
puts Regexp.last_match(1)

Redundant self detected.
Open

      if self.select_values.dup.empty?
Severity: Minor
Found in app/models/memory.rb by rubocop

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

Wrap stabby lambda arguments with parentheses.
Open

   scope :in_calendaries, -> calendaries_in do
Severity: Minor
Found in app/models/memory.rb by rubocop

Check for parentheses around stabby lambda arguments. There are two different styles. Defaults to require_parentheses.

Example: EnforcedStyle: require_parentheses (default)

# bad
->a,b,c { a + b + c }

# good
->(a,b,c) { a + b + c}

Example: EnforcedStyle: requirenoparentheses

# bad
->(a,b,c) { a + b + c }

# good
->a,b,c { a + b + c}

Use 3 (not 2) spaces for indentation.
Open

        selector.unshift("#{join_name}.*")
Severity: Minor
Found in app/models/reading.rb by rubocop

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'

Do not use spaces between -> and opening brace in lambda literals

Severity: Minor
Found in app/models/calendary.rb by rubocop

This cop checks for spaces between -> and opening parameter brace in lambda literals.

Example: EnforcedStyle: requirenospace (default)

# bad
  a = -> (x, y) { x + y }

  # good
  a = ->(x, y) { x + y }

Example: EnforcedStyle: require_space

Do not use space inside array brackets.
Open

      selector = [ 'descriptions.text AS _value' ]
Severity: Minor
Found in app/models/calendary.rb by rubocop

Checks that brackets used for array literals have or don't have surrounding space depending on configuration.

Example: EnforcedStyle: space

# The `space` style enforces that array literals have
# surrounding space.

# bad
array = [a, b, c, d]

# good
array = [ a, b, c, d ]

Example: EnforcedStyle: no_space

# The `no_space` style enforces that array literals have
# no surrounding space.

# bad
array = [ a, b, c, d ]

# good
array = [a, b, c, d]

Example: EnforcedStyle: compact

# The `compact` style normally requires a space inside
# array brackets, with the exception that successive left
# or right brackets are collapsed together in nested arrays.

# bad
array = [ a, [ b, c ] ]

# good
array = [ a, [ b, c ]]

%w-literals should be delimited by [ and ].
Open

      types = %w(Resurrection Repose Writing Appearance Translation Sanctification)
Severity: Minor
Found in app/models/memory.rb by rubocop

This cop enforces the consistent usage of %-literal delimiters.

Specify the 'default' key to set all preferred delimiters at once. You can continue to specify individual preferred delimiters to override the default.

Example:

# Style/PercentLiteralDelimiters:

#     default: '[]'
#     '%i':    '()'

# good
%w[alpha beta] + %i(gamma delta)
