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.

Constructor Details

This class inherits a constructor from RuboCop::AST::Node

Instance Method Details

#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 literaly of type ‘type`.

Parameters:

  • type (Symbol) (defaults to: nil) —

    an optional percent literal type

Returns:

  • (Boolean) —

    whether the array is enclosed in percent brackets

  else

  end
end

#square_brackets? ⇒ Boolean

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

Returns:

  • (Boolean) —

    whether the array is enclosed in square brackets

#values ⇒ Array<Node>

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

Returns:

  • (Array<Node>) —

    an array of value nodes
