class Prism::LocalVariableWriteNode

表示对局部变量的写入。

foo = 1
^^^^^^^

属性

depth [R]

为了找到该变量的声明，我们需要遍历的语义作用域的数量。

foo = 1         # depth 0

tap { foo = 1 } # depth 1

计算深度的具体规则可能因 Ruby 实现的不同而有所差异，因为它们并未在语言中指定。有关更多信息，请参阅 Prism 文档。

name [R]

局部变量的名称，这是一个标识符。

foo = :bar # name `:foo`

abc = 123  # name `:abc`

value [R]

要写入局部变量的值。它可以是任何非空表达式。

foo = :bar
      ^^^^

abc = 1234
      ^^^^

请注意，由于局部变量的名称在解析其值之前就已经知道，因此局部变量可以出现在其自身写入的值中是有效的。

foo = foo

初始化一个新的 LocalVariableWriteNode 节点。

=== (other)

Source

# File lib/prism/node.rb, line 12477
def ===(other)
  other.is_a?(LocalVariableWriteNode) &&
    (name === other.name) &&
    (depth === other.depth) &&
    (name_loc.nil? == other.name_loc.nil?) &&
    (value === other.value) &&
    (operator_loc.nil? == other.operator_loc.nil?)
end

实现节点的相等性判断。这实际上是 ==，但不比较 location 的值。仅检查 location 是否存在。
