  int listen_port = 21110;//listen tcp port for debugger interface

  lua_State* L = luaL_newstate();//create lua state

  lrdb::server debug_server(listen_port);
  debug_server.reset(L);//assign debug server to lua state(Required before script load)

  bool ret = luaL_dofile(L, luafilepath);

  debug_server.reset(); //unassign debug server (Required before lua_close )
  lua_close(L);

Lua module

If you using standalone Lua. you can use lua c mocule.

Build and Install with LuaRocks

luarocks install lrdb

Build module your self

mkdir build
cd build
cmake ../ -DLUA=lua-5.3
cmake --build --target lrdb_server

Generated lrdb_server.so or lrdb_server.dll

Use module

lrdb = require("lrdb_server")
lrdb.activate(21110) --21110 is using port number. waiting for connection by debug client.

--debuggee lua code
dofile("luascript.lua");

lrdb.deactivate() --deactivate debug server if you want.
