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)

Source

# File lib/prism/node.rb, line 14696
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

Initialize a new RangeNode node.

type ()

Source

# File lib/prism/node.rb, line 14795
def self.type
  :range_node
end

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

Public Instance Methods

=== (other)

Source

# File lib/prism/node.rb, line 14801
def ===(other)
  other.is_a?(RangeNode) &&
    (flags === other.flags) &&
    (left === other.left) &&
    (right === other.right) &&
    (operator_loc.nil? == other.operator_loc.nil?)
end

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 14707
def accept(visitor)
  visitor.visit_range_node(self)
end

# File lib/prism/node.rb, line 14712

  [left, right]
end

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

Also aliased as: deconstruct

comment_targets ()

Source

# File lib/prism/node.rb, line 14725

Source

# File lib/prism/node.rb, line 14717
def compact_child_nodes
  compact = [] #: Array[Prism::node]
  compact << left if left
  compact << right if right
  compact

copy (node_id: self.node_id, location: self.location, flags: self.flags, left: self.left, right: self.right, operator_loc: self.operator_loc)

Source

def copy(node_id: self.node_id, location: self.location, flags: self.flags, left: self.left, right: self.right, operator_loc: self.operator_loc)
  RangeNode.new(source, node_id, location, flags, left, right, operator_loc)
end

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

deconstruct ()

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

Alias for: child_nodes

exclude_end? ()

Source

# File lib/prism/node.rb, line 14743
def exclude_end?
  flags.anybits?(RangeFlags::EXCLUDE_END)
end

operator_loc ()

Source

# File lib/prism/node.rb, line 14767
def operator_loc
  location = @operator_loc
  return location if location.is_a?(Location)
  @operator_loc = Location.new(source, location >> 32, location & 0xFFFFFFFF)
end

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

save_operator_loc (repository)

Source

# File lib/prism/node.rb, line 14775
def save_operator_loc(repository)
  repository.enter(node_id, :operator_loc)
end
