Instance Attribute Details

#name ⇒ Object (readonly)

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`

def name
  @name
end

#value ⇒ Object (readonly)

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

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

Instance Method Details

#===(other) ⇒ Object

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