构建Lua解释器:虚拟机的基础 在本篇,我们正式进入到Lua解释器的开发阶段(这是一个遵循Lua 5.3标准的项目)。本篇并不直接接入到设计和实现语法分析器和词法分析器的阶段,而是先设计和实现Lua虚拟机的基础数据结构(包括Lua最基本的数据结构,如基本数据类型、表示虚拟机状态的global_State和lua_State结构、在函数调用中...

假设script.lua中有一个函数myfunction: function myfunction(a, b) return a + b end 六、Lua 脚本的调试技巧 (一)打印调试信息 在Lua 脚本中,可以使用print函数来输出调试信息。这是一种简单而有效的调试方法,可以帮助你了解脚本的执行流程和变量的值。
Note that this method does not wait for a pong frame from the remote end. Back to TOC send_pong syntax: bytes, err = wb:send_pong() syntax: bytes, err = wb:send_pong(msg) Sends out apongframe with an optional message specified by themsgargument. Returns the number of bytes that ha...

相等判断JavaScript提供三种不同的值比较操作:严格相等("triple equals" 或 "identity"),使用 === ,宽松相等("double equals") ,使用 ==以及 Object.is (ECMAScript 2015/ ES6 新特性)简而言之,在比较两件事情时,双等号将执行类型转换; 三等号将进 ...
