class RuboCop::Cop::Style::RedundantSelf

Checks for redundant uses of ‘self`.

The usage of ‘self` is only needed when:

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. Also allows the use of `self.it` without arguments in blocks, as in `0.times { self.it }`, following `Lint/ItWithoutArgumentsInBlock` cop.

@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
