Do not use space inside array brackets. Open
language_codes = [ context[:locales] ].flatten
- Read upRead up
- Exclude checks
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 ]]
Space inside parentheses detected. Open
.order( :describable_type )
- Read upRead up
- Exclude checks
Checks for spaces inside ordinary round parentheses.
Example:
# bad

# good

Redundant self
detected. Open
selector = self.select_values.dup
- Read upRead up
- Exclude checks
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

Check for parentheses around stabby lambda arguments.
There are two different styles. Defaults to require_parentheses
.
Example: EnforcedStyle: require_parentheses (default)

# good
->(a,b,c) { a + b + c}
Example: EnforcedStyle: requirenoparentheses
# bad
->(a,b,c) { a + b + c }
# good
->a,b,c { a + b + c}

at 33, 29 is not aligned with if
at 30, 9. Open
raise NameError ;end ;end ;end
- Read upRead up
- Exclude checks
This cop checks whether the end keywords are aligned properly.
Three modes are supported through the EnforcedStyleAlignWith
configuration parameter:
If it's set to keyword
(which is the default), the end
shall be aligned with the start of the keyword (if, class, etc.).
If it's set to variable
the end
shall be aligned with the
left-hand-side of the variable assignment, if there is one.
If it's set to start_of_line
, the end
shall be aligned with the
start of the line where the matching keyword appears.
Example: EnforcedStyleAlignWith: keyword (default)
# bad
variable = if true
end
# good
variable = if true
end
Example: EnforcedStyleAlignWith: variable
# bad
variable = if true
end
# good
variable = if true
end
Example: EnforcedStyleAlignWith: startofline
# bad
variable = if true
end
# good
puts(if true
end)

# bad
blah { |i|
foo(i) }
# good

Use the lambda
method for multiline lambdas. Open
scope :by_title, -> title do
- Read upRead up
