《Lua设计与实现》读书笔记2

lua.h

开头有定义版本号，这里用的5.4.6

#define LUA_VERSION_MAJOR	"5"
#define LUA_VERSION_MINOR	"4"
#define LUA_VERSION_RELEASE	"6"

#define LUA_VERSION_NUM			504
#define LUA_VERSION_RELEASE_NUM		(LUA_VERSION_NUM * 100 + 6)

#define LUA_VERSION	"Lua " LUA_VERSION_MAJOR "." LUA_VERSION_MINOR
#define LUA_RELEASE	LUA_VERSION "." LUA_VERSION_RELEASE
#define LUA_COPYRIGHT	LUA_RELEASE "  Copyright (C) 1994-2023 Lua.org, PUC-Rio"
#define LUA_AUTHORS	"R. Ierusalimschy, L. H. de Figueiredo, W. Celes"

Lua数据结构类型定义

/*
** basic types
*/
#define LUA_TNONE		(-1)		//无类型

#define LUA_TNIL		0			//空类型
#define LUA_TBOOLEAN		1		//布尔类型
#define LUA_TLIGHTUSERDATA	2		//指针				//void *
#define LUA_TNUMBER		3			//数据				//lua_Number
#define LUA_TSTRING		4			//字符串				//TString
#define LUA_TTABLE		5			//表				//Table
#define LUA_TFUNCTION		6		//函数				//CClosure、LClosure
#define LUA_TUSERDATA		7		//Lua内部指针		//void *
#define LUA_TTHREAD		8			//Lua虚拟机、协程	//lua_State

#define LUA_NUMTYPES		9		//类型数目

lobject.h

存储数据结构文件
数据类型扩展

/*
** Extra types for collectable non-values
*/
#define LUA_TUPVAL	LUA_NUMTYPES  /* upvalues */
#define LUA_TPROTO	(LUA_NUMTYPES+
