Checks if the length of a method exceeds some maximum value. Comment lines can optionally be allowed. The maximum allowed length is configurable.

You can set constructs you want to fold with CountAsOne. Available are: 'array', 'hash', 'heredoc', and 'method_call'. Each construct will be counted as one line regardless of its actual size.

NOTE: The ExcludedMethods and IgnoredMethods configuration is deprecated and only kept for backwards compatibility. Please use AllowedMethods and AllowedPatterns instead. By default, there are no methods to allowed.

Example: CountAsOne: ['array', 'heredoc', 'method_call']

def m
  array = [       # +1
    1,
    2
  ]

  hash = {        # +3
    key: 'value'
  }

  <<~HEREDOC      # +1
    Heredoc
    content.
  HEREDOC

  foo(            # +1
    1,
    2
  )
end               # 6 points

Access modifiers should be surrounded by blank lines.

Example: EnforcedStyle: around (default)

# bad
class Foo
  def bar; end
  private
  def baz; end
end

# good
class Foo
  def bar; end

  private

  def baz; end
end

Example: EnforcedStyle: only_before

# bad
class Foo
  def bar; end
  private
  def baz; end
end

# good
class Foo
  def bar; end

  private
  def baz; end
end

Looks for uses of Perl-style regexp match backreferences and their English versions like $1, $2, $&, &+, $MATCH, $PREMATCH, etc.

Example:

# bad
puts $1

# good
puts Regexp.last_match(1)

    @stripped_query = @query.gsub(/\(?(-?site:\S+)\b\/?\)?/i) do

Enforces using // or %r around regular expressions.

Example: EnforcedStyle: slashes (default)

# bad
snake_case = %r{^[\dA-Z_]+$}

# bad
regex = %r{
  foo
  (bar)
  (baz)
}x

# good
snake_case = /^[\dA-Z_]+$/

# good
regex = /
  foo
  (bar)
  (baz)
/x

Example: EnforcedStyle: percent_r

# bad
snake_case = /^[\dA-Z_]+$/

# bad
regex = /
  foo
  (bar)
  (baz)
/x

# good
snake_case = %r{^[\dA-Z_]+$}

# good
regex = %r{
  foo
  (bar)
  (baz)
}x

Example: EnforcedStyle: mixed

# bad
snake_case = %r{^[\dA-Z_]+$}

# bad
regex = /
  foo
  (bar)
  (baz)
/x

# good
snake_case = /^[\dA-Z_]+$/

# good
regex = %r{
  foo
  (bar)
  (baz)
}x

Example: AllowInnerSlashes: false (default)

# If `false`, the cop will always recommend using `%r` if one or more
# slashes are found in the regexp string.

# bad
x =~ /home\//

# good
x =~ %r{home/}

Example: AllowInnerSlashes: true

# good
x =~ /home\//

Helps you transition from mutable string literals to frozen string literals. It will add the # frozen_string_literal: true magic comment to the top of files to enable frozen string literals. Frozen string literals may be default in future Ruby. The comment will be added below a shebang and encoding comment. The frozen string literal comment is only valid in Ruby 2.3+.

Note that the cop will accept files where the comment exists but is set to false instead of true.

To require a blank line after this comment, please see Layout/EmptyLineAfterMagicComment cop.

Safety:

This cop's autocorrection is unsafe since any strings mutations will change from being accepted to raising FrozenError, as all strings will become frozen by default, and will need to be manually refactored.

Example: EnforcedStyle: always (default)

# 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
  # ...
end

# good
# frozen_string_literal: false

module Bar
  # ...
end

Example: EnforcedStyle: never

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

module Baz
  # ...
end

# good
module Baz
  # ...
end

Example: EnforcedStyle: always_true

# The `always_true` style enforces that the frozen string literal
# comment is set to `true`. This is a stricter option than `always`
# and forces projects to use frozen string literals.
# bad
# frozen_string_literal: false

module Baz
  # ...
end

# bad
module Baz
  # ...
end

# good
# frozen_string_literal: true

module Bar
  # ...
end

Enforces the presence (default) or absence of parentheses in method calls containing parameters.

In the default style (require_parentheses), macro methods are allowed. Additional methods can be added to the AllowedMethods or AllowedPatterns list. These options are valid only in the default style. Macros can be included by either setting IgnoreMacros to false or adding specific macros to the IncludedMacros list.

Precedence of options is all follows:

1. AllowedMethods
2. AllowedPatterns
3. IncludedMacros

eg. If a method is listed in both IncludedMacros and AllowedMethods, then the latter takes precedence (that is, the method is allowed).

In the alternative style (omit_parentheses), there are three additional options.

1. AllowParenthesesInChaining is false by default. Setting it to true allows the presence of parentheses in the last call during method chaining.

2. AllowParenthesesInMultilineCall is false by default. Setting it to true allows the presence of parentheses in multi-line method calls.

3. AllowParenthesesInCamelCaseMethod is false by default. This allows the presence of parentheses when calling a method whose name begins with a capital letter and which has no arguments. Setting it to true allows the presence of parentheses in such a method call even with arguments.

NOTE: Parentheses are still allowed in cases where omitting them results in ambiguous or syntactically incorrect code. For example, parentheses are required around a method with arguments when inside an endless method definition introduced in Ruby 3.0. Parentheses are also allowed when forwarding arguments with the triple-dot syntax introduced in Ruby 2.7 as omitting them starts an endless range. And Ruby 3.1's hash omission syntax has a case that requires parentheses because of the following issue: https://bugs.ruby-lang.org/issues/18396.

Example: EnforcedStyle: require_parentheses (default)

# bad
array.delete e

# good
array.delete(e)

# good
# Operators don't need parens
foo == bar

# good
# Setter methods don't need parens
foo.bar = baz

# okay with `puts` listed in `AllowedMethods`
puts 'test'

# okay with `^assert` listed in `AllowedPatterns`
assert_equal 'test', x

Example: EnforcedStyle: omit_parentheses

# bad
array.delete(e)

# good
array.delete e

# bad
foo.enforce(strict: true)

# good
foo.enforce strict: true

# good
# Allows parens for calls that won't produce valid Ruby or be ambiguous.
model.validate strict(true)

# good
# Allows parens for calls that won't produce valid Ruby or be ambiguous.
yield path, File.basename(path)

# good
# Operators methods calls with parens
array&.[](index)

# good
# Operators methods without parens, if you prefer
array.[] index

# good
# Operators methods calls with parens
array&.[](index)

# good
# Operators methods without parens, if you prefer
array.[] index

Example: IgnoreMacros: true (default)

# good
class Foo
  bar :baz
end

Example: IgnoreMacros: false

# bad
class Foo
  bar :baz
end

Example: AllowParenthesesInMultilineCall: false (default)

# bad
foo.enforce(
  strict: true
)

# good
foo.enforce \
  strict: true

Example: AllowParenthesesInMultilineCall: true

# good
foo.enforce(
  strict: true
)

# good
foo.enforce \
  strict: true

Example: AllowParenthesesInChaining: false (default)

# bad
foo().bar(1)

# good
foo().bar 1

Example: AllowParenthesesInChaining: true

# good
foo().bar(1)

# good
foo().bar 1

Example: AllowParenthesesInCamelCaseMethod: false (default)

# bad
Array(1)

# good
Array 1

Example: AllowParenthesesInCamelCaseMethod: true

# good
Array(1)

# good
Array 1

Example: AllowParenthesesInStringInterpolation: false (default)

# bad
"#{t('this.is.bad')}"

# good
"#{t 'this.is.better'}"

Example: AllowParenthesesInStringInterpolation: true

# good
"#{t('this.is.good')}"

# good
