# 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.
