This cop checks for unused method arguments.

Example:

# bad
 
def some_method(used, unused, _unused_but_allowed)
  puts used
end

Example:

# good
 
def some_method(used, _unused, _unused_but_allowed)
  puts used
end

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:
#   PreferredDelimiters:
#     default: '[]'
#     '%i':    '()'
 
# good
%w[alpha beta] + %i(gamma delta)
 
# bad
%W(alpha #{beta})
 
# bad
%I(alpha beta)

This cop checks for the use of JSON class methods which have potential security issues.

Autocorrect is disabled by default because it's potentially dangerous. If using a stream, like JSON.load(open('file')), it will need to call #read manually, like JSON.parse(open('file').read). If reading single values (rather than proper JSON objects), like JSON.load('false'), it will need to pass the quirks_mode: true option, like JSON.parse('false', quirks_mode: true). Other similar issues may apply.

Example:

# always offense
JSON.load("{}")
JSON.restore("{}")
 
# no offense
JSON.parse("{}")

This cop checks for unused method arguments.

Example:

# bad
 
def some_method(used, unused, _unused_but_allowed)
  puts used
end

Example:

# good
 
def some_method(used, _unused, _unused_but_allowed)
  puts used
end

Example:

# Style/PercentLiteralDelimiters:
#   PreferredDelimiters:

# good
%w[alpha beta] + %i(gamma delta)
 
# bad
%W(alpha #{beta})
 
# bad
%I(alpha beta)

This cop checks for the formatting of empty method definitions. By default it enforces empty method definitions to go on a single line (compact style), but it can be configured to enforce the end to go on its own line (expanded style).

Note: A method definition is not considered empty if it contains comments.

Example: EnforcedStyle: compact (default)

# bad
def foo(bar)
end
 
def self.foo(bar)
end
 
# good
def foo(bar); end
 
def foo(bar)
  # baz
end
 
def self.foo(bar); end

Example: EnforcedStyle: expanded

# bad
def foo(bar); end
 
def self.foo(bar); end
 
# good
def foo(bar)
end
 
def self.foo(bar)
end

This cop checks for interpolation in a single quoted string.

Example:

# bad
 
foo = 'something with #{interpolation} inside'

Example:

# good
 
foo = "something with #{interpolation} inside"

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.

# Style/PercentLiteralDelimiters:
#   PreferredDelimiters:

end

end
 
# good

def foo(bar)

end
 
def self.foo(bar); end

Example: EnforcedStyle: expanded

# bad
def foo(bar); end
 
def self.foo(bar); end
 
# good
def foo(bar)
end
 
def self.foo(bar)
end

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?

Use a guard clause instead of wrapping the code inside a conditional expression

Example:

# bad
def test
  if something
    work
  end
end
 
# good
def test
  return unless something
  work
end
 
# also good
def test
  work if something
end
 
# bad
if something
  raise 'exception'
else
  ok
end
 
# good
raise 'exception' if something
ok

This cop checks for identical lines at the beginning or end of each branch of a conditional statement.

Example:

# bad
if condition
  do_x
  do_z
else
  do_y
  do_z
end
 
# good
if condition
  do_x
else
  do_y
end
do_z
 
# bad
if condition
  do_z
  do_x
else
  do_z
  do_y
end
 
# good
do_z
if condition
  do_x
else
  do_y
end
 
# bad
case foo
when 1
  do_x
when 2
  do_x
else
  do_x
end
 
# good
case foo
when 1
  do_x
  do_y
when 2
  # nothing
else
  do_x
  do_z
end

This cop checks for unused method arguments.

Example:

# bad
 
def some_method(used, unused, _unused_but_allowed)
  puts used
end

Example:

# good
 
def some_method(used, _unused, _unused_but_allowed)
  puts used
end

This cop checks for extra/unnecessary whitespace.

Example:

# good if AllowForAlignment is true
name      = "RuboCop"
# Some comment and an empty line
 
website  += "/bbatsov/rubocop" unless cond
puts        "rubocop"          if     debug
 
# bad for any configuration
set_app("RuboCop")
website  = "https://github.com/bbatsov/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:
#   PreferredDelimiters:
#     default: '[]'
#     '%i':    '()'
 
# good
%w[alpha beta] + %i(gamma delta)
 
# bad
%W(alpha #{beta})
 
# bad
%I(alpha beta)

Example: EnforcedStyle: compact (default)

# bad
def foo(bar)
end
 
def self.foo(bar)
end
 
# good
def foo(bar); end
 
def foo(bar)
  # baz
end
 
def self.foo(bar); end

# bad
def foo(bar); end
 
def self.foo(bar); end
