# 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
            ^^^

new (source, node_id, location, flags, name, name_loc, value, operator_loc)
Source

    # File lib/prism/node.rb, line 8043
    def initialize(source, node_id, location, flags, name, name_loc, value, operator_loc)
      @source = source

      @name = name
      @name_loc = name_loc
      @value = value
      @operator_loc = operator_loc
    end

Initialize a new `GlobalVariableWriteNode` node.

type ()
Source

    # File lib/prism/node.rb, line 8151
    def self.type
      :global_variable_write_node
    end

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

### Public Instance Methods

=== (other)
Source

    # File lib/prism/node.rb, line 8157
    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.
