在LUA库中添加自己的函数库总结

1.首先下载基于VS的LUA源码，地址为https://luabinaries.luaforge.net/download.html

2.在LIB工程中添加mylib.c文件

3.在文件当中添加如下的代码

#include "lua.h" #include "lauxlib.h" #include "lualib.h" static int myfun(lua_State* L) { printf("myfun is succeed!"); return 0; } static const struct luaL_Reg mylib[] = { {"myfun",myfun}, {NULL,NULL} }; LUALIB_API int luaopen_mylib(lua_State* L) { luaL_register(L,"mylib",mylib); }

4。在lualib.h中增加如下定义

#define LUA_MYLIBNAME "mylib" LUALIB_API int (luaopen_mylib) (lua_State *L);

5.在linit.c，中将

static const luaL_Reg lualibs[] = { {"", luaopen_base}, {LUA_LOADLIBNAME, luaopen_package}, {LUA_TABLIBNAME, luaopen_table}, {LUA_IOLIBNAME, luaopen_io}, {LUA_OSLIBNAME, luaopen_os}, {LUA_STRLIBNAME, luaopen_string}, {LUA_MATHLIBNAME, luaopen_math}, {LUA_DBLIBNAME, luaopen_debug}, {LUA_MYLIBNAME,luaopen_mylib}, {NULL, NULL} };

最后增加一行，如上图所示

6.更新include目录的lualib.h文件

7.测试如下

#include "stdafx.h" extern "C" { #include "lua.h" #include "lualib.h" #include "lauxlib.h" } int main() { lua_State *L = luaL_newstate(); lua_cpcall(L, luaopen_base, 0); lua_cpcall(L, luaopen_io, 0); lua_cpcall(L, luaopen_string, 0); lua_cpcall(L,luaopen_mylib,0); const char *buf = "mylib.myfun()";//注意调用规则 //luaL_loadstring(L, buf); int s = luaL_loadstring(L, buf); if ( s==0 ) { s = lua_pcall(L, 0, LUA_MULTRET, 0); } lua_close(L); getchar(); return 0; }
