Hmm ... and to think I just got by with:
void dumpstack_lua(lua_State *L)
{
int max = max = lua_gettop(L);
int i;
/*----------------------------------------------------------
; however you want to handle the output---I normally go for
; syslog, but for this example, I'm using printf()
;---------------------------------------------------------*/
printf("----LUA STACK DUMP----\n");
for (i = 1 ; i <= max ; i++)
{
const char *name;
const char *type;
int ri;
lua_getglobal(L,"tostring");
lua_pushvalue(L,i);
lua_call(L,1,1);
name = lua_tostring(L,-1);
type = luaL_typename(L,i);
ri = i - max - 1;
printf("Stack: %d %d - %s %s",i,ri,type,name);
lua_pop(L,1);
}
}
I could probably do more with functions, table and userdata, but for my
own use, this has been good enough. Also, you could take advantage of Lua
(like I did by calling tostring()) and provide a Lua function to dump
tables, function names, etc.
