class Prism::RangeNode

Represents the use of the ‘..` or `…` operators.

1..2
^^^^

c if a =~ /left/ ... b =~ /right/
     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Attributes

left[R]

The left-hand side of the range, if present. It can be either ‘nil` or any [non-void expression](github.com/ruby/prism/blob/main/docs/parsing_rules.md#non-void-expression).

1...
^

hello...goodbye
^^^^^

right[R]

The right-hand side of the range, if present. It can be either ‘nil` or any [non-void expression](github.com/ruby/prism/blob/main/docs/parsing_rules.md#non-void-expression).

..5
  ^

1...foo
    ^^^

If neither right-hand or left-hand side was included, this will be a MissingNode.

Public Class Methods

new(source, node_id, location, flags, left, right, operator_loc) click to toggle source

Initialize a new RangeNode node.

# File lib/prism/node.rb, line 13224
def initialize(source, node_id, location, flags, left, right, operator_loc)
  @source = source
  @node_id = node_id
  @location = location
  @flags = flags
  @left = left
  @right = right
  @operator_loc = operator_loc
end

type() click to toggle source

Return a symbol representation of this node type. See ‘Node::type`.

def self.type
  :range_node
end

Public Instance Methods

===(other) click to toggle source

Implements case-equality for the node. This is effectively == but without comparing the value of locations. Locations are checked only for presence.

# File lib/prism/node.rb, line 13321
def ===(other)
  other.is_a?(RangeNode) &&
    (flags === other.flags) &&
    (left === other.left) &&
    (right === other.right) &&
    (operator_loc.nil? == other.operator_loc.nil?)
end

accept(visitor) click to toggle source

def accept: (Visitor visitor) -> void

# File lib/prism/node.rb, line 13235
def accept(visitor)
  visitor.visit_range_node(self)
end

child_nodes() click to toggle source

def child_nodes: () -> Array[nil | Node]

# File lib/prism/node.rb, line 13240
def child_nodes
  [left, right]
end

Also aliased as: deconstruct

comment_targets() click to toggle source

def comment_targets: () -> Array[Node | Location]

# File lib/prism/node.rb, line 13253
def comment_targets
  [*left, *right, operator_loc] #: Array[Prism::node | Location]
end

compact_child_nodes() click to toggle source

def compact_child_nodes: () -> Array

# File lib/prism/node.rb, line 13245
def compact_child_nodes
  compact = [] #: Array[Prism::node]
  compact << left if left
  compact << right if right
  compact
end

copy(node_id: self.node_id, location: self.location, flags: self.flags, left: self.left, right: self.right, operator_loc: self.operator_loc) click to toggle source

def copy: (?node_id: Integer, ?location: Location, ?flags: Integer, ?left: Prism::node?, ?right: Prism::node?, ?operator_loc: Location) -> RangeNode

# File lib/prism/node.rb, line 13258

  RangeNode.new(source, node_id, location, flags, left, right, operator_loc)
end

deconstruct()

def deconstruct: () -> Array[nil | Node]

Alias for: child_nodes

deconstruct_keys(keys) click to toggle source

def deconstruct_keys: (Array keys) -> { node_id: Integer, location: Location, left: Prism::node?, right: Prism::node?, operator_loc: Location }

# File lib/prism/node.rb, line 13266
def deconstruct_keys(keys)
  { node_id: node_id, location: location, left: left, right: right, operator_loc: operator_loc }
end

end

operator() click to toggle source

def operator: () -> String

# File lib/prism/node.rb, line 13300

end

operator_loc() click to toggle source

The location of the ‘..` or `…` operator.

# File lib/prism/node.rb, line 13293
