The call lua_rawseti (L, t, key) (again for t positive) is equivalent to. Note that both functions use raw operations

I am investigating a strange problem: on Windows, lua_rawgeti() does not return back the value to which I have created reference, but a nil. Code: lua_State *L = luaL_newstate(); luaL_requiref(L,. You can retrieve an object referred by reference r by calling lua_rawgeti(L, t, r). Function luaL_unref frees a reference and its associated object. If the object at the top of the stack is nil, luaL_ref returns the constant LUA_REFNIL. The constant LUA_NOREF is guaranteed to be different from any reference returned by luaL_ref In Lua API, the basic C int type is essentially used for stack indexes(why not) and for boolean values (since C89 does not have a booltype). The functions lua_rawgeti, lua_rawseti and lua_createtable somewhatcreate an exception, as they have a n argument of type int also :LUA_API void (lua_rawgeti) (lua_State *L, int idx, int n);LUA_API. printf(lua_rawgeti(%d)\n, n); 또한 writeln ()을 test.d에 추가하여 lua_rawgeti ()를 호출하는 시점을 알려줍니다.

쨋든 Lua C API로 루아 배열에서 정수 인덱스로 접근해서 값을 얻어와 보겠습니다. 그것을 가능케 하는 마법의 함수는 바로 . lua_rawgeti(lua_State*, int index, int n) 함수입니다. index 는 값을 얻어올 테이블이 있는 스택의 위치구요, n을 접근할 인덱스입니다 lua_rawgeti(L, LUA_REGISTRYINDEX, LUA_REFNIL); pushes a nil, as expected. The reference system also defines the constant LUA_NOREF, which is an integer different from any valid reference. It is useful to mark references as invalid. As with LUA_REFNIL, any attempt to retrieve LUA_NOREF returns nil and any attempt to release it has no effect

If possible, in your C functions, try and use lua_rawget() and lua_rawgeti() for table access, since it avoids the tag method checks. Be sure to use lua_rawgeti() for indexed access.

你可以通过调用 lua_rawgeti(L, t, r) 来找回由 r 引用的对象。 函数 luaL_unref 用来释放一个引用关联的对象. 如果栈顶的对象是 nil， luaL_ref 将返回常量 LUA_REFNIL。 常量 LUA_NOREF 可以保证和 luaL_ref 能返回的其它引用值不同。 luaL_Re Recently, I was using Lua [1] in one of my projects.

  2. Prefer lua_newtable() to lua_createtable() It has been observed that lua_newtable() is generally faster than lua_createtable() by a rather wide margin. This might seem counterintuitive, as lua_createtable() preallocates a known amount of memory in bulk to save steps, but it has a very negative effect on the cache for situations where the performance improvement would have otherwise made a.

Adventures in Lua stack overflows. Hammerspoon is heavily dependent on Lua - it's the true core of the application, so it's unavoidable that we have to interact with Lua's C API in a lot of places. If you've never used it before, Lua's C API is designed to be very simple to integrate with other code, but it also places a fairly high burden on.
