class Prism::GlobalVariableWriteNode

Represents writing to a global variable.

$foo = 1
^^^^^^^^

Attributes

name[R]

The name of the global variable, which is a ‘$` followed by an [identifier](github.com/ruby/prism/blob/main/docs/parsing_rules.md#identifier). Alternatively, it can be one of the special global variables designated by a symbol.

$foo = :bar  # name `:$foo`

$_Test = 123 # name `:$_Test`

value[R]

The value to write to the global variable. It can be any [non-void expression](github.com/ruby/prism/blob/main/docs/parsing_rules.md#non-void-expression).

$foo = :bar
       ^^^^

$-xyz = 123

Public Class Methods

new(source, node_id, location, flags, name, name_loc, value, operator_loc) click to toggle source

Initialize a new GlobalVariableWriteNode node.

# File lib/prism/node.rb, line 6944
def initialize(source, node_id, location, flags, name, name_loc, value, operator_loc)
  @source = source
  @node_id = node_id
  @location = location
  @flags = flags
  @name = name
  @name_loc = name_loc
  @value = value
  @operator_loc = operator_loc
end

type() click to toggle source

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

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 7044
def ===(other)
  other.is_a?(GlobalVariableWriteNode) &&
    (name === other.name) &&
    (name_loc.nil? == other.name_loc.nil?) &&
    (value === other.value) &&
    (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 6956
def accept(visitor)
  visitor.visit_global_variable_write_node(self)
end

child_nodes() click to toggle source

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

Also aliased as: deconstruct

comment_targets() click to toggle source

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

# File lib/prism/node.rb, line 6971
def comment_targets
  [name_loc, value, operator_loc] #: Array[Prism::node | Location]
end

end

deconstruct()

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

Alias for: child_nodes

deconstruct_keys(keys) click to toggle source

def name_loc
  location = @name_loc
  return location if location.is_a?(Location)
  @name_loc = Location.new(source, location >> 32, location & 0xFFFFFFFF)
