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

Public Class Methods

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

Source

# File lib/prism/node.rb, line 16419
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.

Public Instance Methods

depth → Integer

Source

# File lib/prism/node.rb, line 16521
def depth
  @depth
end

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 → Symbol

Source

# File lib/prism/node.rb, line 16507
def name
  @name
end

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`
