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
        ^^^

Source

# File lib/prism/node.rb, line 7785
def initialize(source, node_id, location, flags, name, name_loc, value, operator_loc)
  @source = source
  @node_id = node_id
  @location = location

Public Instance Methods

=== (other)

Source

# File lib/prism/node.rb, line 7899
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

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