Instance Attribute Details



  

    #name   (readonly)
  



  

    
The name of the global variable, which is a $ followed by anidentifier. Alternatively, it can be one of the special global variables designated by a symbol.


$foo = :bar  # name {:$foo}

$_Test = 123 # name `:$_Test`

# File 'lib/prism/node.rb', line 6993



attr_reader :name


  








  

    #value   (readonly)
  



  

    
The value to write to the global variable. It can be anynon-void expression.


$foo = :bar
       ^^^^

$-xyz = 123

Instance Method Details



  

    #===(other)  
  



  

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