class Prism::LocalVariableReadNode

Represents reading a local variable. Note that this requires that a local variable of the same name has already been written to in the same scope, otherwise it is parsed as a method call.

foo
^^^

Attributes

depth [R]

The number of visible scopes that should be searched to find the origin of this local variable.

foo = 1; foo # depth 0

bar = 2; tap { bar } # depth 1

The specific rules for calculating the depth may differ from individual Ruby implementations, as they are not specified by the language. For more information, see the Prism documentation.

name [R]

The name of the local variable, which is an identifier.

x      # name `:x`

_Test  # name `:_Test`

Note that this can also be an underscore followed by a number for the default block parameters.

_1     # name `:_1`

Public Class Methods

new (source, node_id, location, flags, name, depth)

Source

# File lib/prism/node.rb, line 12882
def initialize(source, node_id, location, flags, name, depth)
  @source = source
  @node_id = node_id
  @location = location
  @flags = flags
  @name = name
  @depth = depth
end

Initialize a new LocalVariableReadNode node.

type ()

Source

# File lib/prism/node.rb, line 12961
def self.type
  :local_variable_read_node
end

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

Public Instance Methods

=== (other)

Source

# File lib/prism/node.rb, line 12967
def ===(other)
  other.is_a?(LocalVariableReadNode) &&
    (name === other.name) &&
    (depth === other.depth)
end

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