Overview

A node extension for ‘array` nodes. This will be used in place of a plain node when the builder constructs the AST, making its methods available to all `array` nodes within RuboCop.

Instance Method Details

#bracketed? ⇒ Boolean

Checks whether the ‘array` literal is delimited by either percent or square brackets

brackets

Returns:

  • (Boolean) —

    whether the array is enclosed in percent or square

def bracketed?
  square_brackets? || percent_literal?
end

#each_value {|node| ... } ⇒ self, Enumerator

Calls the given block for all values in the ‘array` literal.

Yield Parameters:

  • node (Node) —

    each node

Returns:

  • (self) —

    if a block is given

  • (Enumerator) —

    if no block is given

  self
end

#percent_literal? ⇒ Boolean #percent_literal?(type) ⇒ Boolean

Checks whether the ‘array` literal is delimited by percent brackets.

Overloads:

  • #percent_literal? ⇒ Boolean

    Check for any percent literal.

  • #percent_literal?(type) ⇒ Boolean

    Check for percent literal of type ‘type`.

    Parameters:

    • type (Symbol) —

      an optional percent literal type

Returns:

  • (Boolean) —

    whether the array is enclosed in percent brackets

end

#square_brackets? ⇒ Boolean

Checks whether the ‘array` literal is delimited by square brackets.

Returns:

  • (Boolean) —

#values ⇒ Array<Node>

Returns an array of all value nodes in the ‘array` literal.

Returns:

  • (Array<Node>) —

    an array of value nodes
