This cop checks for non-ascii (non-English) characters in comments. You could set an array of allowed non-ascii chars in AllowedChars attribute (empty by default).
Example:

# Translates from English to Japanese
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
Wrap stabby lambda arguments with parentheses. Open

- Read upRead up
- Exclude checks
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 the lambda
method for multiline lambdas. Open
scope :by_token, -> text do
- Read upRead up
- Exclude checks
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
