Basic Ideas on Lua debugger Development

AboutLua DebuggerThe basic idea of development is the content to be introduced in this article. In the past, we had to createLuaRemoteDebuggerFor use by the task department. Here is a brief introduction.DebuggerThe server class is CLuaDebug!

CLuaDebug initialization:

Implement callback Hook Function

 
 

  
  
Static void LuaDebugCallBack (lua_State * L, lua_Debug * ar)
  
  
{
  
  
Lua_getinfo (L, "S", ar );
  
  
Switch (ar-> event)
  
  
{
  
  
Case LUA_HOOKRET:
  
  
M_iDeepFunc --;
  
  
Break;
  
  
Case LUA_HOOKCALL:
  
  
M_iDeepFunc ++;
  
  
Break;
  
  
Case LUA_HOOKLINE:
  
  
String strSource = ar-> source + 1;
  
  
ULONG ulLine = ar-> currentline;
  
  
// Print the global variable lua_pushvalue (state, LUA_GLOBALSINDEX), stack information (lua_getstack, lua_getinfo (, "nSlf", & d), and local variable (lua_getlocal ))
  
  
.......
  
  
Break;
  
  
Defalut:
  
  
Break;
  
  
}
  
  
}
 
 

Set the hook function:

 
 

  
  
lua_sethook(state, CLuaDebug::LuaDebugCallBack, LUA_MASKLINE|LUA_MASKCALL|LUA_MASKRET, 0); 
 
 

Summary: I have finished introducing the basic idea of Lua debugger development. I hope this article will be helpful to you!
