This cop checks for tabs inside the source code.

Example:

# bad
# This example uses a tab to indent bar.
def foo
  bar
end

# good
# This example uses spaces to indent bar.
def foo
  bar
end

This cop checks whether the end keywords are aligned properly for do end blocks.

Three modes are supported through the EnforcedStyleAlignWith configuration parameter:

start_of_block : the end shall be aligned with the start of the line where the do appeared.

start_of_line : the end shall be aligned with the start of the line where the expression started.

either (which is the default) : the end is allowed to be in either location. The autofixer will default to start_of_line.

Example: EnforcedStyleAlignWith: either (default)

# bad

foo.bar
   .each do
     baz
       end

# good

variable = lambda do |i|
  i
end

Example: EnforcedStyleAlignWith: startofblock

# bad

foo.bar
   .each do
     baz
       end

# good

foo.bar
  .each do
     baz
   end

Example: EnforcedStyleAlignWith: startofline

# bad

foo.bar
   .each do
     baz
       end

# good

foo.bar
  .each do
     baz
end

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'
  end
end
end

Here we check if the parameters on a multi-line method call or definition are aligned.

Example: EnforcedStyle: withfirstparameter (default)

# good

foo :bar,
    :baz

# bad

foo :bar,
  :baz

Example: EnforcedStyle: withfixedindentation

# good

foo :bar,
  :baz

# bad

foo :bar,
    :baz

This cop checks for tabs inside the source code.

Example:

# bad
# This example uses a tab to indent bar.
def foo
  bar
end

# good
# This example uses spaces to indent bar.
def foo
  bar
end

This cop checks for unwanted parentheses in parameterless method calls.

Example:

# bad
object.some_method()

# good
object.some_method

This cop checks whether the end keywords are aligned properly for do end blocks.

Three modes are supported through the EnforcedStyleAlignWith configuration parameter:

start_of_block : the end shall be aligned with the start of the line where the do appeared.

start_of_line : the end shall be aligned with the start of the line where the expression started.

either (which is the default) : the end is allowed to be in either location. The autofixer will default to start_of_line.

Example: EnforcedStyleAlignWith: either (default)

# bad

foo.bar
   .each do
     baz
       end

# good

variable = lambda do |i|
  i
end

Example: EnforcedStyleAlignWith: startofblock

# bad

foo.bar
   .each do
     baz
       end

# good

foo.bar
  .each do
     baz
   end

Example: EnforcedStyleAlignWith: startofline

# bad

foo.bar
   .each do
     baz
       end

# good

foo.bar
  .each do
     baz
end

This cop checks for tabs inside the source code.

Example:

# bad
# This example uses a tab to indent bar.
def foo
  bar
end

# good
# This example uses spaces to indent bar.
def foo
  bar
end

Checks if uses of quotes match the configured preference.

Example: EnforcedStyle: single_quotes (default)

# bad
"No special symbols"
"No string interpolation"
"Just text"

# good
'No special symbols'
'No string interpolation'
'Just text'
"Wait! What's #{this}!"

Example: EnforcedStyle: double_quotes

# bad
'Just some text'
'No special chars or interpolation'

# good
"Just some text"
"No special chars or interpolation"
"Every string in #{project} uses double_quotes"

This cops checks for inconsistent indentation.

The difference between rails and normal is that the rails style prescribes that in classes and modules the protected and private modifier keywords shall be indented the same as public methods and that protected and private members shall be indented one step more than the modifiers. Other than that, both styles mean that entities on the same logical depth shall have the same indentation.

Example: EnforcedStyle: normal (default)

# bad
class A
  def test
    puts 'hello'
     puts 'world'
  end
end

# bad
class A
  def test
    puts 'hello'
    puts 'world'
  end

  protected

    def foo
    end

  private

    def bar
    end
end

# good
class A
  def test
    puts 'hello'
    puts 'world'
  end
end

# good
class A
  def test
    puts 'hello'
    puts 'world'
  end

  protected

  def foo
  end

  private

  def bar
  end
end

Example: EnforcedStyle: rails

# bad
class A
  def test
    puts 'hello'
     puts 'world'
  end
end

# bad
class A
  def test
    puts 'hello'
    puts 'world'
  end

  protected

  def foo
  end

  private

  def bar
  end
end

# good
class A
  def test
    puts 'hello'
    puts 'world'
  end
end

# good
class A
  def test
    puts 'hello'
    puts 'world'
  end

  protected

    def foo
    end

  private

    def bar
    end
end

This cops checks if empty lines around the bodies of blocks match the configuration.

Example: EnforcedStyle: empty_lines

# good

foo do |bar|

  # ...

end

Example: EnforcedStyle: noemptylines (default)

# good

foo do |bar|
  # ...
end

This cops checks for indentation that doesn't use the specified number of spaces.

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'
