full_message_loc ()

来源

# File lib/prism/node_ext.rb, line 331
def full_message_loc
  attribute_write? ? message_loc&.adjoin("=") : message_loc
end

当调用节点设置了 attribute_write 标志时，表示该调用正在使用属性写入语法。这要么是调用 []= 的方法调用，要么是调用以 = 结尾的方法。无论哪种方式，= 符号都出现在源代码中。

Prism 返回不带 = 符号的 message_loc，因为消息和 = 符号之间可能存在任意数量的空格。但是，有时您需要包含内部空格和 = 符号的完整消息的位置。此方法提供此功能。
